Description

Radiation transmission reducing component base material for relatively high concentrations of land, gardens, schoolyards, stadium grounds or lawns, on farmland, concrete, asphalt, road slopes, building walls, roofs Above, around and around the waste accumulated by decontamination work, installed as a free-standing wall structure, construction and garden, school ground, stadium ground or lawn, on farmland, forest, building wall, roof Planted by installing walls on the top and surrounding areas of land with relatively high concentrations of radiation, borders of neighboring land facing buildings, and waste accumulated in decontamination work, which is installed on the top surface to make green spaces Further, the present invention relates to a radiation protective green space and a radioactive material diffusion prevention green space structure using the radiation transmission reducing component base material suitable for being installed in a gutter inside a rainwater infiltration basin.

The nuclear power plant and its surrounding area or the radioactive material handling business facility and its surrounding area are polluted by radioactive materials scattered in the natural environment due to an accident at the nuclear power plant and an accident at the radioactive material handling business facility. In addition, radioactive materials are decontaminated in the event of an accident. However, the ground, soil, turf, etc. that are contaminated with radioactive materials are peeled off by surface, concrete, asphalt, Decontamination work is carried out by methods such as peeling or high-pressure washing at contaminated parts such as surfaces and roofs. However, there are concerns about the re-scattering of radioactive materials and the sedimentation of the water stream due to the movement leading to storage of decontaminated materials and washing. In addition, radiation from radioactive materials remains in the place after decontamination. In addition, radiation remains on the ground surface even though decontaminated materials are buried underground. In addition, it is difficult to secure land for storing decontaminated materials. Moreover, a high concentration of radiation is emitted when a large amount of decontaminated material is concentrated. In addition, if radiation remains in the land or building next to the decontaminated land, the radioactive material that adheres to or penetrates the adjacent land or building is scattered by the wind, or the radioactive material that rainwater adheres to or penetrates the building surface is allowed to flow. There are not a few places where high-concentration radiation radiates in the drainage facility, on the ground, or in the ground.

In addition, radioactive materials adhering to the ground due to strong winds, driving, etc. float in the surrounding area and adhere to the ground and buildings again. There are challenges to radiation.

All of the harmful effects of radiation caused by the existence of radioactive materials on humans, animals, and various other ecology have not been elucidated. In addition, it is more dangerous to orally dispose of radioactive materials floating from a location contaminated with radioactive materials, but it is not easy to remove radioactive materials from a contaminated living environment area.
At present, as a solution for such problems, a plurality of sheets such as iron plates, sheets and mats in which heavy metal powders and particles are integrated as additives in rubber and resin are obtained in order to obtain a radiation shielding effect (for example, patents) Reference 4). In addition, heavy metal plates, heavy concrete plates, concrete blocks, and heavy objects such as large amounts of soil that are not contaminated with radioactive materials have been selected and installed on a place where radiation radiates. It is also known to reduce the radiation by installing a heavy structure as a wall around the place where the radiation radiates.

On the other hand, the greening technology which contains 90% of soil volume ratio already exists (for example, refer patent documents 1, 2, and 3). This patent document technology verifies the amount of evapotranspiration comparable to forests and provides a heat island mitigation effect (verifies that the outdoor temperature of 50 cm above the rooftop grass in midsummer is reduced by 1 ° C.). In addition, the storage effect of heavy rain that occurs frequently due to the amount of water stored in green spaces is remarkable. Furthermore, a lawn in which water does not bleed onto the lawn surface when the soil is saturated with soil water is suitable for a stadium. In addition, wood, herbs and crops can all be produced by forcing cultivation. For example, Yae red weeping cherry tree is planted on a ship and grown with stable growth. In addition, for example, spinach grown without agrochemicals has grown to a height of 150 cm. As described above, it is clear that the above-mentioned patent document technique is a special technique. In this greening technology, the water consumption of plants can be reduced by combining the aeration environment, carbon environment, trace element fertilizer environment, and drainage environment suitable for the growth of plant roots in the soil structure. Absent. The soil water content is also affected by the evapotranspiration of the leaves, and the amount of water content in the soil decreases significantly in summer. Considering the effect of reducing radiation transmission, due to the water content of the greening technology, for example, when the soil thickness is 12 cm, the mass of the soil and underdrain basement and activated carbon adhering permeable sheet, turfgrass sod mass and water retention The turfgrass greenery structure can be designed with a combined weight of water saturation of soil of 167 kg / m ² (100 l water saturation). It is a common value for those skilled in the art that the radiation transmittance estimated from this weight is reduced by about 75%. However, for example, at least about 5 to 7 l / day of m ² is consumed by evapotranspiration on a midsummer day, that is, when the water content of the above-described culture soil excellent in water retention is saturated, Turf grass will consume soil moisture in 20 days, if there is rainfall during this water consumption, water will increase in the soil, but if there is no precipitation, the moisture content in the soil will decrease every day. The water consumption of the turf will reduce the load on the soil and increase the radiation transmission rate. It is essential to replenish the turf with water in order to keep the transmission constant and to prevent the turf grass from wilting and dying. Become. In addition, it is possible to introduce general land other than the water-retaining soil described in the patent document and create it to increase the thickness of the soil and increase the weight. However, it is impractical to bring in a large amount of soil material that is not contaminated with radioactive materials from a remote area free of contamination. In addition, the transportation cost is high and the introduction is difficult. In addition, since the water content and soil load increase by using a large amount of water-retaining soil described in the patent document, the radiation transmittance is reflected in the total load of the soil structure, but a sufficient reduction effect is obtained. However, in order to maintain the radiation transmission reduction rate at a value as close to 100% as possible, it is indispensable to maintain the soil weight and water content at a constant level. is there. As explained above, the factors that increase or decrease the weight of green soil are affected by the amount of water consumed by the plant and the weather conditions on the top surface of the soil. It is to be lost. In addition, in order to obtain a radiation transmission reduction effect that should correspond to radiation of cesium with a long physical half-life of 30 years, it is necessary to reduce the dose transmission that should cope with the dose emitted by cesium over at least the half-life period. Requires an effective soil moisture content and a substrate and soil structure with physical functions to prevent radioactive material scattering and flow movement,
However, it is difficult for those skilled in the art to create inexpensive soil that has a high water content required for reducing radiation transmission and that maintains a constant amount of water that is necessary for the stable growth of plants. It was. Moreover, it has been difficult for those skilled in the art to create a structure including a liquid phase part and a gas phase part that maintain a static state without being affected by external force. Furthermore, it is not easy to predict that a reduction effect excellent in fixation and shielding of radioactive materials, which is a physics area, will be obtained, and also because the fields related to plant growth and radioactive materials are different, Such creation of new soil was not easily conceivable.

As described above, according to the radiation transmission reduction component base material and the radiation transmission reduction component base material of the present invention, the radiation protection green space and the radioactive substance diffusion prevention green space structure according to the present invention can be used for water content. Water can be stored in the space, and the radiation transmission reduction effect can be stably exhibited. And the effect which prevents scattering by the function in which a fine substance carbon physically adsorbs a radioactive substance is also acquired. The factor of this effect is that the water retention base material is filled in the water-containing space created from the structure of the front and rear thin plates, the plurality of ribs, and the peripheral closing member, so that the water retention base material is affected by the external force due to the load. Without changing the static state, the water content can be maintained permanently. Furthermore, the water retention base material is not affected by changes in water content caused by evaporation due to the surrounding high-temperature thermal environment, changes in degradation of the water retention base material due to microorganisms, and changes in soil water content due to evapotranspiration of plants. There is no change in the water content present.
With this configuration, the weight of the hollow plate-like member, the weight of the water retention base material, and the weight of the initial moisture content contained in the water retention base material can be maintained, so that the radiation transmission reduction effect can be continuously exhibited. Moreover, since water can be poured into the water-containing space at or near the installation site, the burden of transportation is reduced. Furthermore, the burden of the operator who carries the heavy article which exhibits the radiation shielding effect which has been conventionally used can be reduced.

Further, the shielding factor of the invention that can be estimated apart from the above-mentioned radiation transmission reduction effect factor is that radiation electromagnetic waves are suppressed by a high-density resin and a molded resin.

Insulation and heat resistance resin materials, rubber sheets with pressure-bonded resin and rubber, and fiber molded bodies made of inorganic blast furnace slag, which is generated when iron is the main raw material, have heat resistance. It is possible to suppress radiation electromagnetic waves.

The fact that the gas phase part derived from the density of the thermoplastic resin, the fiber made from mineral and the carbon, and the carbon is formed in a special shape can maintain the static state without being affected by the external force. A factor for maintaining the static state is to suppress the heat conduction of radiation.
Furthermore, a large amount of water or a liquid with a high specific gravity, which is a compound of hydrogen and oxygen present in a static state on a water retention substrate (liquid phase part) that is an aggregate of fibers made from minerals with a high water content, is in the gas phase part. It is conceivable to suppress the electromagnetic wave and heat conduction of radiation based on the structure integrated with.

In addition to the property of not allowing electricity and heat to pass through in this way, a single compound that maintains water and oxygen in a static state or a liquid phase part and a gas phase part of the present invention that are configured at appropriate positions are formed in each structure. As a result, it was predicted that the radiation shielding effect, which is different from the radiation shielding effect caused by the load, will increase significantly. Moreover, although the hollow plate-shaped member and each base material which have an air layer of the said invention show a radiation transmission reduction effect exceptionally, they can be manufactured cheaply.

Since the water-containing space 5 is sealed by providing the member 10, the water content is good.

The water retention substrate 7 is a sheet in which fibers are impregnated with a superabsorbent polymer. By filling this sheet into the water-containing space 5 and pouring water, the superabsorbent polymer impregnated in the sheet of the water retention substrate 7 quickly absorbs water and penetrates the entire sheet. The amount of water absorption varies depending on the nature of the water to be poured and the amount of the superabsorbent polymer contained in the sheet, but approximately 8 to 12 times the weight of the sheet containing the superabsorbent polymer is absorbed by the sheet. Therefore, water injection work becomes easy.

Moreover, according to the structure of FIG. 5, since it is the structure which closed the peripheral part of the water-containing space 5, it can store water so that the static state of the water 6 in the water retention base material may be stabilized. In addition, the water injected into the water retaining substrate 6 in the state where the band-like through hole 11 and the through hole 12 are closed by the closing member 10 shown in the upper part (a) and the peripheral part is closed. Since there is almost no loss of eyes, the radiation transmission reduction effect can be exhibited stably.

In addition, as shown to the upper figure (a) of FIG. 5, the strip | belt-shaped through-hole 11 for the purpose of making the through-hole 12 and the water-containing space 5 communicate with the surface thin plate 2 of the hollow plate-shaped body with which the water retention base material 6 was filled.

After cutting and cutting, or applying heat to the inverted triangular metal bar and applying pressure to the hollow plate from the surface of the thin plate 2 at the end of the hollow plate, It is the figure by which the part which bends a part surface in the direction of the through-hole 12, and welded the surface which faces is closed. It is preferable to close the end portion by this closing method because the strength of the water-containing space 5 increases because the end portion is firmly closed. However, although it is recommended that the water-retaining substrate 6 be filled before it is closed, this end closing method is shown as an example method and is not limited thereto.

However, the plate-like body made of the material constituting the front thin plate 2, the back thin plate 3 and the rib 4 of the radiation transmission reducing component base material is closed using a waterproof airtight tape, an aluminum foil tape, a water shielding sheet or the like, or It is preferably closed with concave or convex rubber, cement, welded resin rod, anticorrosion metal plate, concave anticorrosion metal plate and the like.

Moreover, although the front thin plate 2 and the back thin plate 3 are the hollow plate-shaped bodies laminated | stacked via the some rib 4, when the thickness of a hollow plate-shaped body becomes thin, the area | region of a water-containing space 5 and a water-containing volume ratio will decrease. Therefore, the thickness is preferably 3 mm to 100 mm, more preferably 15 mm to 200 mm. Then, its weight varies depending on the amount of resin and additives amount required hollow plate-like body shaped generally preferably ^{0.5kg / m 2 ~25kg / m 2} , more preferably 1.5kg ^/ m 2 ~15kg / M ² .

<Third Embodiment>
This embodiment is based on the second invention and comprises a hollow plate-like body in which a back thin plate and a front thin plate in which a large number of through-holes are formed are stacked via a large number of ribs. The rib includes a plurality of plate-like ribs arranged substantially parallel to each other, and at least one end portion of the water-containing space located at a longitudinal end of the plurality of plate-like ribs is closed, This through-hole corresponds to a specific example of a configuration characterized in that it includes a belt-like through-hole drilled so as to intersect the plurality of plate-like ribs.

This embodiment will be described with reference to the drawings.
In the perspective view shown in the upper diagram (a) of FIG. 6 (refer to the lower diagram (b) for the inside), the end surfaces are closed by the ribs 4 positioned on the left and right end surfaces of the hollow plate-like body 1. And the state where the both end surfaces of the plate-shaped rib 4 in the longitudinal direction are also closed as the closed end surfaces 9 is shown. However, the interior of the hollow plate-like body has a water-containing space 5 between the plurality of plate-like ribs and the plate-like ribs, and is filled with the water retaining substrate 6. This closing method is the closing welding 18 by thermal processing described in the above embodiment. A strip-shaped through hole 11 is formed in the front thin plate 2 shown on the upper surface of the perspective view.

The formation of the band-like through-holes 11 formed so as to intersect with the plurality of plate-like ribs 4 makes it easy to inject water, and the rain from the band-like through-holes 11 formed in a plurality of planes.

Since it will be less, water resources will be used effectively.

Moreover, since the water | moisture content contained in the water retention base material 6 has closed the peripheral part of the hollow plate-like body 1, it can maintain a static state and can hold | maintain a water content. In addition, although the water leak from the strip | belt-shaped through-hole 11 generate | occur | produces in the water amount where the amount of rainfall or water injection exceeds the water content of the water retention base material 6, it does not affect the maximum water content of the water retention base material 6. Moreover, even if the hollow plate-like body 1 is installed on a flat surface or an inclined surface in a stationary state, water hardly leaks from the through-hole 11 due to factors other than those described above, so that the radiation transmission reduction effect is permanent.

Although the width | variety of the strip | belt-shaped through-hole 11 is not specifically limited, If a width | variety becomes narrow, it will affect the water flow. On the other hand, if the width becomes too wide, the water content will be affected by the environment outside the hollow plate-like body and the water content will be reduced. Therefore, the width may be 1 mm to 15 mm, but preferably 1 mm to 8 mm. In addition, the distance between the belt-like through hole 11 and the belt-like through hole 11 may be 10 cm or more, but even a narrower space does not affect water injection or the like.
Further, the cross-sectional shape of the belt-like through hole 11 is not particularly limited, and examples thereof include a rectangular shape, a U shape, a V shape, and a dovetail shape. The shape of the band-shaped through hole 11 is not particularly limited, and examples thereof include a band such as a straight line, a curve, and a meandering line, a polygon such as a triangle, a quadrangle, and a hexagon, a circle, an ellipse, a geometric pattern, and a spiral pattern.

FIG. 11 is a perspective view showing an example of this embodiment. First, the closing member 10 is erected on the periphery of the front thin plate 2 and the back thin plate 3 to close the peripheral edge. Two front closure members are shown removed to facilitate unraveling the spatial elements inside the hollow plate. Cylindrical ribs 4 are dotted on the upper surface of the back thin plate 3, the periphery thereof is a water-containing space 5, and the surface thin plate 2 shown above the water-containing space 5 and the rib 4 penetrates in a strip shape.

In this way, it is recommended to produce a thick hollow plate that can secure the water content necessary for reducing radiation transmission and the water content necessary for the growth of plants when using it as a greening wall. In addition, although a plant seed | species can be selected according to the magnitude | size of the planting hole 13, if the planting hole 13 is 15 cm in diameter, a plant of a tree is possible.

Further, a water retention base material that fills the water-containing space inside the hollow plate-like body can be recommended because rock wool is suitable for growing plants. In addition, in order to separate the water-containing region necessary for reducing radiation transmission and the water-containing region necessary for the growth of the plant, a hollow rib formed by forming a through-hole or a notch in the hollow plate-like body is configured, For example, it is desirable to make the area for planting the area inside the hollow rib.

This embodiment will be described with reference to the drawings.

The upper figure (a) of FIG. 12 includes a water retaining substrate 6 between the water shielding plate 19 and the water shielding plate 19 (or 22), and the two right and left water shielding plates and the water retaining substrate 6 are integrated. It is a perspective view of an example of a radiation transmission reduction constituent substrate in which a through hole 12 into which a bolt screw that is a fixing member 16 intended to be inserted is opened. Moreover, the lower figure (b) is sectional drawing which showed the partially fixed location of the upper figure (a). In the example shown in the figure, the water retaining substrate 6 is sandwiched between the left and right water shielding plates 19 and 22, and by using bolt screws and nuts as the fixing member 16, the water shielding plates 19 and 22 and the water retaining substrate 6 are separated. It is a fixed specification that keeps the gap at regular intervals. In this fixing method, although it depends on the shape of the water shielding plates 19 and 22, it is preferable to integrate at least four places using bolt screws and nuts.

In addition, the water shielding plate 22 shown on the right side of the figure uses a hollow undercover plate 22 having a water shielding function on the back thin plate as a water shielding plate. According to this configuration, the total weight of the ^two water-impervious plates combined with a weight of 10 kg / m ² and a water-containing saturated weight of the water-retaining base material 6 made of rock wool with a thickness of 7 cm is 100 kg / m ^2, which causes It is estimated that the transmission reduction rate can be about 50%. Further, when the thickness of the water-retaining substrate 6 is 16 cm, the total weight is 240 kg / m ² and the radiation transmission reduction rate is about 80%. Since it is estimated that it can be made, it is further useful.
For this specification, it is desirable to fix with bolts, nuts, and washers as fixing members that match the thickness of the water retaining substrate 6 and the water shielding plate 22, but the fixing members and fixing methods are arbitrary fixing members and fixing means. It is possible to make the structure.

It is also useful for shielding a high-concentration dose because a radiation transmission reducing component base material in the form of 450 kg of granular cotton and 2600 kg of saturated water content can be produced. In order to withstand the water-impregnated weight 2600 kg pressure, the joint surface of each main surface is selected to make use of connecting members such as I-type joints having strength and right-angle hollow L-type joints. It is preferable to do.

FIG. 13A shows a peripheral edge of the left and right water shielding plates 19 and 22 in such a manner that the water retaining substrate 6 is sandwiched between the water shielding plates 19 and 22 and the formation is maintained using the fixture 16. The outer thin plate between the ribs in the bent portion of the hollow plate 21 which is a single water shielding plate is cut so that the inner thin plate is cut at a substantially right angle. It is a perspective view of an example before attaching the water shielding board frame 10 made into the shape to the edge part of the periphery formed by the water retention base material 6 being pinched | interposed by the water shielding boards 19 and 22. FIG.
In addition, the L shape which fixes the water shielding board frame 10 was shown in the figure. It is preferable to use rivets or screws and nuts for joining the L shape and the water shielding plate frame.
The water shielding plates 19 and 22 have water injection through holes 12. The through-hole 12 is formed by cutting the front thin plate, the back thin plate, and the rib of the hollow culvert plate 22 into a circle with an electric tool. The round hollow undercut of the cut-out part can be fitted into the through-hole after water injection, and the through-hole can be closed, thereby returning to the original shape of the water shielding plate. Means are preferred. The number of through holes may be plural in consideration of the water injection time.

Each of the methods for fixing the water shielding plate is performed by using, for example, a binding band made of resin, metal, or fiber woven material in addition to the bolt, nut, and washer of the fixing member 16 shown in the figure. What is necessary is just to manufacture the structure which consists of structures.
In this configuration, since the entire periphery of the water retaining substrate 6 is shielded by the water shielding plates 10 and 19, there is no movement of water, and the initial water injection amount is permanently retained, so that the radiation transmission reduction rate is further stabilized. become. Further, it is also possible to configure the water shielding plate 22 by stacking several sheets in multiple layers.

The lower view (b) of FIG. 13 shows the water shielding plates 19a and 19b having a shape different from the smooth water shielding plate shown in FIGS. 12 and 13 (a). . The water shielding plates 19a and 19b have a convex surface 97 in which the surfaces of the water shielding plates 19a and 19b are formed in a convex shape. The position having a plurality of convex shapes is a checkered convex surface 97 (see the right diagram) shown in the right diagram of FIG. A structure in which a water retaining base material is provided in a region space around the convex portion of the water shielding plate and the upper surface of the convex portion 97 is overlapped with each other so as to be in contact with each other is also useful. In addition, the peripheral edge of the plate having a plurality of shapes of the convex portions 97 is provided with a side wall in the same manner as the thickness of the convex portion 97, and the water retaining base 5 is placed in the water-containing space 5 between the two impermeable box shaped plates. A structure in which the structures stacked with 6 sandwiched therebetween are integrated by the fixing member 16 is also useful for radiation shielding, and the shape of the convex portion 97 may be formed with unevenness.

(C) of FIG. 13 is the shielding of the radioactive material contaminant 71 which has accumulated in the bottom of the side groove 113 where the gutter 114 and the side groove 113 which were shown by the perspective view of (f) are connected, and the rain which flows in the inside of a side groove, etc. It is the perspective view and sectional drawing (g) of a radiation transmission reduction structure base material which have the water flow function of the waste_water | drain. All of the water shielding plates 19 shown in the perspective view are PVC resin plates. The water retaining substrate 6 is filled with the water shielding plate 19. A water conduit 108 is provided on a part of the water retaining substrate 6. This water pipe 108 is a vinyl chloride pipe. In addition, a through-hole 12 that matches the size of the end surface of the water conduit 108 is formed in the water shielding plate 19 shown in a lower part different from the perspective view at substantially the same position as the end surface of the water conduit 108. The water shielding plate 19 in which the through hole is opened is fixed to the end surface of the water conduit 108 by using the screw of the fixing member 16. Also on the back surface not shown in the perspective view, a water shielding plate 19 having a through hole 12 of a size matching the end surface of the same water pipe 108 is fixed by using a screw of the fixing member 16.

In addition, the water shielding plate 19 on the upper surface of the perspective view is provided with a through hole 12 of a water injection port 25 for water injection. The through hole 12 is formed by cutting a water shielding plate 19 formed of a vinyl chloride resin into a circle with an electric tool. Since the circular plate of the cut-out hollowed portion can be fitted into the through hole after water injection and the through hole can be closed, thereby returning to the original shape of the water shielding plate, the means for opening and closing the water inlet is preferable. The number of through holes may be plural in consideration of the water injection time.

The size of the radiation transmission reducing component base material having the function of shielding the radioactive substance contaminants 71 present in the vicinity of the bottom of the side groove and having a water passage function may be a size matching the inner dimension of the side groove. Moreover, although it is an example, in the inner area | region of the inner bottom of the radiation transmission reduction structure base material in which the water shielding board 19 was formed in the side groove | channel of width 45cm by width 40cm which consists of green resin, height 65cm, and length 102cm. A water retention substrate made by mixing nine pieces of vinyl chloride pipes with an outer diameter of 114 mm and a length of 100 cm in three rows of three horizontal rows and mixing rock wool and activated carbon in the outer region of the vinyl chloride pipes. The radiation transmission reduction rate of the filled structure is such that the thickness of the water retention base material filled in the upper surface region of the vinyl chloride tube is 30 cm, the saturation load of water poured into the water retention base material is 225 kg, Since it is estimated that the transmission reduction rate can be about 75%, it is useful. Further, since the saturated load of water 225 kg including the load of the water retention base material is a static load without movement, it is useful for fixing the radioactive substance existing between the outer bottom surface and the side groove of the base material for reducing radiation transmission. preferable. Moreover, what added the pigment in any one of the bitumen, green, blue, black, gray, and red to the raw material of the water-shielding board 19 which comprises a radiation transmission reduction structure base material is more preferable for shielding. In addition, since the weight before water content of this radiation transmission reduction component base material is as light as about 45 kg, it is useful because it can be installed by 1 to 3 workers in the side groove.
In addition, the number of water pipes configured in this way may be determined in consideration of the number that does not hinder the drainage function of the side grooves as much as possible and the outer diameter of the PVC pipe. If the outer diameter of the vinyl chloride tube is large, one may be used. In addition, it is preferable to calculate the thickness and filling amount of the water-retaining substrate 6 so as to be considered to be most effective in reducing the transmission of radiation in consideration of the dose value emitted by the radioactive substance. Moreover, the water retention base material 6 which mixed activated carbon, a resin pellet, and powder rubber is useful.

The cross-sectional view shown in Fig. (D) is an example of a radiation transmission reducing component base material. According to this structure, the water-impervious plate 19 is a water retaining substrate shown in the drawing with the hollow plate 21 provided with a plurality of ribs between the front thin plate and the back thin plate as the upper surface, the bottom surface, the side surface, the front surface, and the rear surface. 19 and a water pipe 108 (a horizontal row of vinyl chloride pipes). It should be noted that the water shielding plates 19 may not be provided on both end surfaces of the water flow pipe 108 in the longitudinal direction. However, it is preferable to fix each water pipe 108 to the water shielding plate 19 using a fixing tool such as an adhesive tape, heat welding, a screw, a bolt, or a nut. In addition, a water injection port 25 for water injection is shown on the upper surface. The water injection port 25 is a rectangular water injection port 25 in which the front and rear thin plates and the ribs of the hollow plate 21 that is the water shielding plate 19 are not cut. It is preferable to close the water injection port 25 by fitting the hollow plate 21 in which the water injection port 25 is opened after pouring water into the water retaining substrate.

FIG. 4E shows a hollow plate 21 in which a plurality of ribs are provided between a front thin plate and a back thin plate in the same manner as FIG. 96 region), the rear surface (excluding the drainage channel 96 region), the left and right side walls of the drainage channel 96 shown in the figure, and a middle plate on the side walls. In the cross-sectional view shown, the water retaining substrate 6 is filled between the upper water shielding plate 19 and the middle water shielding plate 19. Further, the water retaining base material 6 is filled in the space between the side wall (water shielding plate 19 and hollow plate 21) of the drainage channel 96 from the outer region, the side surface, the bottom surface water shielding plate 19, and the middle water shielding plate 19. . In addition, a water inlet 25 for pouring water into the water retaining substrate 6 is provided in the upper water shielding plate 19. When water is poured from the water filling port, the water is submerged from the water filling port provided in the water shielding plate 19 provided in the middle stage to the lower water retention base 6. According to this structure, even if it does not comprise a polyvinyl chloride pipe, it is preferable because it has a function of passing water to the rear surface reaching the front surface of the radiation transmission reducing component base material. Further, fixing member 16 nuts for attaching the front and rear water shielding plates to the top, bottom and side water shielding plates are shown respectively.

The outer shape of the present embodiment is a circular pipe shape, a square pipe shape, a square bar shape, a round bar shape, a quadrangular column, a cylindrical shape, a pyramid shape, a square trapezoidal shape, a rectangular parallelepiped, a cube, an ellipse, a hemisphere, a sphere, etc. It may be formed.

Moreover, the water shielding board material of this structure is not specifically limited, It is preferable to select the material demonstrated between [0111] and [0124] described in Embodiment of 1st invention. The molding method is preferably a thermoplastic resin and is preferably molded by extrusion molding, injection molding or the like, but is not limited thereto. In addition, precast concrete, resin concrete, concrete plate, reinforced concrete, and metal plate may be configured as a water shielding plate. In addition, as for the molding method of concrete, it is also preferable to form the water shielding plate by mold forming, mold compacting, or mold compression forming. In addition, a molded form (filled with water-retaining base material) formed into a box shape made of at least one polypropylene resin or polyethylene resin having durability that is free from deterioration of rust and corrosion separate from the water shielding plate of the base material for reducing radiation transmission It is also preferable to select and use a container having a region and a water passage.

<Ninth embodiment>
In the ninth embodiment of the radiation transmission reducing component substrate of FIG. 9B, a plate body formed from a thermoplastic resin, or the back thin plate 3 and the front thin plate 2 are arranged via a plurality of plate-like body ribs 4. A hollow plate-like body 22 in which the plate-like bodies are installed substantially in parallel and a drainage channel 96 is formed, or a front thin plate 2 in which a back thin plate 3 and a plurality of through holes are formed. Is composed of a hollow plate-like body 22 laminated via a plurality of ribs, and the rib is the plate-like body 4, and the plurality of plate-like bodies are installed substantially in parallel to form a drainage channel 96, The through-hole is a band-shaped through-hole 11, and is a base material for reducing radiation transmission, characterized in that it has a culvert plate structure in which a plurality of band-shaped through-holes 11 are formed by crossing the plate-like body.

According to this configuration, it is preferable to manufacture the plate body and the culvert plate structure with reference to the description of the material constituting the hollow plate-like member specified in the first embodiment. In addition, as a specific example of opening the band-shaped through hole, it is specified according to the embodiment of the third invention, so that it is preferably carried out according to the reference. Further, in order to increase the mechanical strength and the radiation transmission reducing effect on the plate body and the undergrowth plate of the ninth embodiment, the plate body, the front thin plate 2, the back thin plate 3, and the plurality of plate-like ribs 4 are provided. It is better to make the thickness thicker, and when the plate body is manufactured by resin molding and when the material constituting the hollow plate member is manufactured by resin molding, adding an antistatic agent and a pigment has an effect of reducing radiation transmission. It is preferable because it can be estimated that the level will be higher. The color of the pigment to be added is preferably dark blue, blue, green, black, gray, brown, purple, or yellow.

That is, the color of a molded product manufactured in general resin molding is, for example, that a finished product is translucent when a polypropylene resin is molded. The translucent plate made by molding a polypropylene resin and the dark culvert plate are preferable for obtaining a radiation transmission reducing effect, but the shielding effect of the translucent resin molded plate and the antistatic agent, bitumen or green pigment are added. It can be predicted that the radiation transmission reduction rate of the resin molded product added and molded is different even if the mass of the resin used for molding is the same. Of course, the plate formed by adding an antistatic agent and a pigment, the foamed plate, the hollow plate and the hollow undercut plate are more useful because the radiation transmission reduction rate can be predicted to be higher. The principle that an antistatic agent is effective for shielding radioactive substances is considered to suppress radiation electromagnetic waves. It is also conceivable that the density of the translucent polypropylene resin suppresses radiation electromagnetic waves and heat. A translucent polypropylene resin is preferable because it does not require the addition of a pigment and is inexpensive. In addition to the thermoplastic resin, a specification in which a thermosetting resin, an FRP resin, or the like is replaced with a thermoplastic resin may be selected. Moreover, although it depends on the mass and thickness of the plate body, hollow plate, and hollow culvert plate, it is preferable to use a plurality of the plates, since the shielding effect appears remarkably.
In addition, the principle that the pigment adsorbs the radioactive substance is that the radioactive substance is adsorbed in the pores of the pigment if, for example, the pore size of the pigment manufactured from mineral or ceramic is approximately the same as the radioactive substance size. Can be guessed. Further, since the density and shape of the molding resin can be presumed to be a factor for reducing the transmission of radioactive substances, the hollow plate-like body is useful as a lightweight base material for reducing the radiation transmission because the drainage channel is an air layer.

In order to provide reinforcement, weather resistance, light resistance, heat resistance, electric resistance, insulation, etc., to the plate body, the front thin plate 2 and the back thin plate 3 constituting the hollow plate, which are configured as a base material for reducing radiation transmission Polyolefin resin such as polyethylene resin and polypropylene resin, polyvinyl chloride resin, polystyrene resin, polyacrylic resin, ABS resin, polyfluorine resin, polycarbonate resin, polyester resin, polyarate resin, polyimide A synthetic resin film or an aluminum foil of a base resin may be laminated by selecting a bonding method such as adhesion, adhesion, vapor deposition, thermal fusion, and a tacker needle. Moreover, it is also preferable to apply an epoxy resin, an acrylic resin, a fluororesin, or a phenol resin on the upper surface of each of the aforementioned resins or aluminum foil. Moreover, a picture pattern, a photograph, a character, etc. may be printed on the synthetic resin film for imparting design properties and the like. In addition, you may select laminating | stacking rubber-coated cloth sheets other than the above specified by the explanatory note of the material which comprises the hollow plate-shaped member of 1st invention. By laminating such materials, the insulating and heat resistance effects increase, which is preferable for reducing radiation transmission.

The front thin plate 2, the back thin plate 3 and the rib 4 formed of a thermoplastic resin may be transparent, translucent or opaque, and are thermoplastic to improve weather resistance, light resistance, heat resistance, moldability and the like. Addition of heat stabilizers, stabilization aids, bone agents, processing aids, antioxidants, light stabilizers, pigments, antistatic agents, inorganic fillers, plasticizers, etc. that are commonly used in resin molding May be.
In order to obtain the effect of adsorbing the radioactive substance, it is preferable to select any one of bitumen, blue, green, black, gray, red, brown, purple and yellow as a pigment and add it at the time of molding the resin.
Alternatively, a paint may be applied to the surface of the formed plate or hollow plate member, or a paint may be applied to the upper surface where a binder such as an acrylic resin is applied. Moreover, it is also preferable to apply a fluororesin or a phenol resin.
In addition, ultrafine activated carbon having pores that match the size of the radioactive substance, or zeolite, ultrafine activated carbon and zeolite may be added to the resin to obtain the radioactive substance adsorption effect. The ultrafine-grained activated carbon and zeolite having a particle size of 980 μm or less are preferable for molding and also suitable for adsorption of radioactive substances.

In addition, the hollow plate-like body of the culvert plate structure in which the belt-like through-holes 11 are formed has a function of smoothly draining rain regardless of a plane or a slope, so that, for example, the ground contaminated with radioactive substances If it is used by laying it on the top surface of soil or agricultural land, the drainage effect of rain, the transmission of radiation released from the ground or soil, and the radioactive material adsorbed on the back thin plate in contact with the ground or soil, fixing the radioactive material Useful for. In addition, it is useful because it is easy to cultivate plants such as crops by creating a soil with good water retention on the upper surface of the surface plate 2 of a hollow plate-like body with a culvert plate structure in which the belt-like through-holes 11 are formed. It is. In addition, the space | gap which has the drainage channel 96 function exists between the upper surface area | region of the surface thin plate 2, and the bottom back surface area | region of the back thin plate 3 which can estimate that a radioactive substance is adsorb | sucked. Due to this void structure, the radioactive material present on the bottom back surface is not touched even if the roots of the plant planted on the top surface of the surface thin plate 2 are elongated. That is, a hollow plate-like body with a culvert plate structure is useful because it prevents the radioactive material contained in the water absorbed by the plant roots.

As other useful uses of the hollow plate-like body of this culvert plate structure, for example, in the soil of farmland where crop production is impossible due to salt damage due to the influence of the tsunami, having the above-described functions, It is useful and preferable in the agricultural field because it can be presumed to have an effect of preventing secondary salt damage on the soil top surface, etc., and on farmland where salt removal work has been performed. Furthermore, it is also useful to lay a hollow plate-shaped body of a culvert plate structure on the upper surface of land contaminated with harmful substances. If this hollow plate is manufactured using an extrusion molding machine with additives such as pigments added to the resin raw material, it can be manufactured endlessly with a width of 130 cm. It is good to manufacture to the magnitude | size which matches the shape and area. The culvert plate having the hollow plate-like body and the band-like through-holes 11 is excellent in rigidity. For example, since the drainage channel 96 has a strength that is not destroyed even by the load of the outrigger of a large vehicle, it is preferable in the field of civil engineering drainage work such as a construction site construction that requires a permanent drainage function. It should be noted that a plate, a hollow plate, and a hollow plate formed by forming the belt-like through-holes 11 are useful because they are provided as a constituent substrate of the present invention.

<Tenth Embodiment>
In the base material for reducing radiation transmission according to the tenth aspect of the invention, the back thin plate 3 shown in FIG. 10A and the front thin plate 2 in which a plurality of through holes are formed have a large number of cylindrical ribs 4. It is comprised in the hollow plate-shaped body 21 before being laminated | stacked through. A drainage channel 96 is formed between the cylindrical ribs, and the belt-like through-hole 11 of the twelfth invention is formed in a perspective view. The front thin plate 2, the back thin plate 3, and a plurality of ribs are integrally formed.
Fig. A shows an annulus-shaped rib, Fig. I shows a square hourglass rib, Fig. C shows a cylindrical rib, and Fig. D shows a plate-like body inside the cylindrical rib. The shape is shown. It is preferable to select one of such rib shapes to manufacture this radiation transmission reducing component base material. Moreover, according to this structure, in order to manufacture the hollow plate-shaped body 22, it is preferable to manufacture based on the description of the material which comprises the hollow plate-shaped member specified in 1st Embodiment. Further, a specific example of opening the belt-like through hole 11 is specified in the third embodiment, and is preferably carried out in accordance with reference. Further, in order to increase the mechanical strength and the radiation transmission reduction effect of the undercut plate of the tenth embodiment, the thickness of the front thin plate 2, the back thin plate 3 and the plurality of ribs 4 may be increased, and the number of ribs is increased. Good.

Moreover, as for the color of the molded product manufactured in general resin molding, for example, when a polypropylene resin is molded, the finished product is translucent. The translucent front and rear thin plates 2 and the back thin plate 3 formed by molding a polypropylene resin which is an insulating polymer are preferable for obtaining a radiation transmission reducing effect. Further, when the polypropylene resin is produced by molding, It is considered that the addition of an antistatic agent and a pigment further enhances the radiation transmission reducing effect. Moreover, it is preferable to add activated carbon and zeolite because it is considered that the radiation transmission reduction effect is further enhanced. The color of the pigment added when the polypropylene resin is produced by molding is preferably dark blue, blue, green, black, gray, or red. Radiation transmission reduction rate is generally the same as the resin mass of the material of the translucent resin molded product that is generally molded and the molded product that is molded by adding antistatic agent, bitumen and green pigment, and further adding activated carbon and zeolite. But I can guess it is different. In addition, the hollow plate-like body of the culvert plate structure in which the belt-like through-holes 11 according to the twelfth invention are formed has a function of smoothly draining rain regardless of a plane or a slope. When laid on the surface of soil contaminated with a substance or soil on a farmland, the radioactive material is adsorbed by the drainage effect of rainfall, the reduction of the transmission of radiation emitted from the ground or the soil, and the back thin plate in contact with the ground or the soil. Therefore, it is useful for fixing radioactive materials. The hollow plate-like body 22 has a structure in which the peripheral side surface of the plate-like body is a drainage port. The advantage that the peripheral side surface becomes a drainage port is preferable for workability because it is possible to omit the direction of the drainage channels when connecting and laying a plurality of pieces on the sloped land.

In order to provide reinforcement, weather resistance, light resistance, heat resistance, electric resistance, insulation, etc., to the plate body, the front thin plate 2 and the back thin plate 3 constituting the hollow plate, which are configured as a base material for reducing radiation transmission Polyolefin resin such as polyethylene resin and polypropylene resin, polyvinyl chloride resin, polystyrene resin, polyacrylic resin, ABS resin, polyfluorine resin, polycarbonate resin, polyester resin, polyarate resin, polyimide A synthetic resin film of aluminum resin or an aluminum foil may be laminated by selecting a bonding method such as adhesion, adhesion, or vapor deposition.

In the configuration of this cross-sectional view, the water retention base 6 is filled in the drainage channel 96. Since the water retention base material is filled, for example, even if this radiation transmission reducing component base material is provided on the inclined surface, only the excess water 58 moves and water is contained in the water retention base material. The water will remain stationary. That is, although there is an effect of switching the water content and the incoming water, it is preferable to keep certain water in a stationary state in the water retention base material of the drainage channel 96 because the radiation transmission reducing effect is continued.

That is, the ribs 4 having different shapes on the left and right sides of the two hollow plate-like bodies 1 are fitted to each other as shown in the center portion of the lower figure (b). For example, the thickness of the front thin plate 2 and the back thin plate 3 of the hollow plate-like body 1 is 3 mm, the thickness of the plurality of ribs 4 is 2 mm, and the ribs 4 having fitting shapes at both ends are also 2 mm. The ribs 4 are 30 mm apart, the hollow plate-like body 1 is 35 mm thick, and the ribs 4 can be manufactured with a length in the longitudinal direction of 6 m. The weight of the water-saturated state of the hollow plate-like body 1 is about 50 to 70 kg / m ² depending on the content of the water-retaining substrate 6, and the radiation shielding rate is about 25% to 35%. Can be estimated. The hollow plate-like body 1 is preferably manufactured by extrusion molding using a vinyl chloride resin as a main material.

Further, when a plurality of hollow plate-like bodies 1 formed with the fitting-shaped ribs 4 are fitted, a wall having a large area can be easily constructed, which is useful for locations that require radiation shielding. In addition, since decomposition is easy, if the hollow plate-like body 1 is composed of four layers, the radiation shielding rate is about 75% (the radiation dose is reduced to about 25%), and the portion that needs to be shielded. It is suitable for. The standard of each member, the front thin plate 2, the back thin plate 3, and the plurality of ribs 4 of the hollow plate-like body 1 described is an example.

It is a radiation protection green space and a radioactive material diffusion prevention green space structure using the radiation transmission reducing component substrate of the 31st or 32nd invention. Providing such a soil layer is preferable because the thermal environment in the soil layer is stabilized. This structure is useful because it can be assumed that the myriad microscopic voids and water content prevent the heat of the soil from increasing, that is, the present invention suppresses the action related to the heat of radiation.

<Thirty-fourth embodiment>
In the thirty-fourth aspect of the invention, a number of through-holes or belt-like through-holes are formed between the rock wool fiber or its molded product and the soil layer, or in the rock wool fiber or its molded product or the soil layer.

According to a fifty-fifth aspect of the invention related to radiation transmission reduction, the front thin plate 2 and the back thin plate 3 are any of a plurality of plates, cylinders, truncated cones, honeycombs, prisms, truncated pyramids, and lattices. The hollow plate-like body 21 laminated through the ribs, the resin plate, the resin sheet, or the rubber sheet is selected, or the upper surface of the radiation transmission reducing component base material according to any one of the first to seventeenth inventions The shape of the culvert is plate-shaped, box-shaped, bowl-shaped, slatted, rugged, sponge-shaped or corrugated-shaped, and has a thickness of 0.03 mm or more on the upper surface of the substrate on which a plurality of through holes are formed, Non-woven fabric with a basis weight of 10 g / m ² or more / or a non-woven fabric on which activated carbon is adhered or impregnated, two non-woven fabrics are joined in a lattice pattern, and fertilizer or a mixture of fertilizer and activated carbon is formed between the upper and lower nonwoven fabrics of the resulting lattice. At least one of the plant-growing sheets encapsulated with A particle-shaped formed body made of rock wool fibers and having a density of 25 kg / m ³ or more is laminated on the upper surface of the material, and a soil layer 33 is laminated on the upper surface of the rock wool fibers. This is a radiation protection green space using the reduced configuration substrate and a greening structure for preventing radioactive material diffusion.

FIG. 55 (a) is a bottom view showing the box body 37 formed of polypropylene resin.
The sectional view (b) in the middle stage is placed on the upper surface of the hollow plate 21 so that the bottom surface of the box 37 shown in FIG. An activated carbon-attached water-permeable sheet 17 is laminated on the upper surface of the bottom surface. It is sectional drawing on which the rock wool cotton-like body 101 with a density of 25 kg / m3 or more and the soil 33 are laminated | stacked on the upper surface of the activated carbon adhesion water-permeable sheet 17. FIG. When the soil structure configured in this way is installed on a location where the radiation dose shows a relatively high value, the dose transmitted through the soil structure is reduced. In order to increase the reduction rate, it is preferable to increase the mass of the soil 33 and the rock wool fluff 101 so that the water content of the soil 33 and the rock wool fluff 101 increases. Further, when forming a box body 37 with a resin, if pigments such as bitumen, blue, green, black, gray, brown are added to polypropylene resin as a thermoplastic resin, the pores of the pigment and the ultrafine particles having a large surface area of the pores It is preferable because it can be presumed that the dose permeated through the soil structure is reduced due to the voids and water content of the activated carbon and the mineral rock wool fibers. That is, the shielding factor other than the load of the structure is that the electromagnetic wave of radiation is suppressed by the polypropylene resin having an insulator. And it is possible that the fine space | gap which consists of a fiber-shaped mineral and carbon suppresses the heat conduction of a radiation. Furthermore, it is thought that it is based on the fact that water, which is a compound of hydrogen and oxygen, is integrated in large quantities. Furthermore, it is also preferable to replace the hollow plate 21 with the hollow plate 21 by selecting any one of the first to seventeenth inventions so that the radiation dose can be estimated to be reduced. A configuration in which one or more of the first to seventeenth inventions are selected is also preferable. The box 37 is an example of the present invention and is not limited thereto.

Rock wool flocculent body 101 is shown in FIG. 1 (a) so that the bottom surface of box 37 faces upward, and rock wool flocculent body 101 is activated carbon-adhered to a position close to the bottom surface of box 37 (FIG. A). The sheet 17 is laminated on the inner region of the box 37 from the upper surface of the sheet 17. And the soil 33 is laminated | stacked on the upper surface of the rock wool cotton-like body 101. FIG. A plant 95 is planted in the soil 33 in the circular inner region of the box 37. The thickness of the box 37 is 18 cm. The total weight of the water 33 and the weight of the hollow culvert plate 22 combined with the soil 33 and the rock wool flocculent body 101 formed in this thickness region is about 240 kg / m ² , and the radiation transmission reduction rate is about 80 % Is estimated to be possible. It should be noted that the addition of a pigment should be selected because it can be predicted that the addition of dark pigments such as blue, green, and black to a polypropylene resin, which is a thermoplastic resin, will improve the radiation transmission reduction rate. As a shielding factor other than the load of the structure, the electromagnetic wave of radiation is suppressed by a polypropylene resin having an insulator. Then, it is conceivable to suppress heat conduction of radiation by the action of oxygen present in the pores of the activated carbon having numerous pores and fiber-shaped slag composed of numerous voids. Furthermore, it is thought that it is based on the fact that water, which is a compound of hydrogen and oxygen, is integrated in large quantities. In addition, the disaster prevention nonwoven fabric sheet made mainly of aramid fiber is laminated on the soil upper surface of the soil structure with this structure, and the structure is integrated with bolts, nuts, etc. of a plurality of fixing members, and the shielding wall of radioactive material is greened Since it can manufacture and provide as a structure, it is preferable. Therefore, this 50th invention is useful.

An upper view (b) of FIG. 15 is a diagram showing a partial cross section of the structure of the lower right view (a), and bolts of the fixing member 16 are attached to the mesh 20 and the water shielding plate 19 shown on the right side. It shows a state in which the nut of the fixing member 16 is tightened by being inserted into a hole provided as a through hole for inserting the fixing member 16 and penetrating the left water shielding plate 19 and the net 20. Note that nuts for preventing external pressure from being applied to the water retention base 6 located inside the right and left water shielding plates 19 are provided on the inner side surfaces of both the water shielding plates 19.
In addition, as shown in the perspective view of FIG. 5A, this structure is a hollow structure in which a back thin plate and a front thin plate having a large number of through-holes are stacked via a plurality of plate-like ribs. The plate-like body is a water shielding plate 19. Then, the left and right surfaces of the water retaining substrate 6 are sandwiched between the water shielding plates 21, the net 20 is laminated on the surface of the water shielding plate 19, and the water retaining substrate 6, the water shielding plate 19 and the net 20 are fixed by the fixing member 16. Is fixed and integrated.
It is preferable to make the water shielding plate into a hollow plate shape as well as a heat insulating effect and increase the strength of the structure. And the heat | fever load with respect to the water content of the water retention base material 6 can be reduced, and the high heat | fever of a structure can be suppressed. That is, it is preferable for the growth environment of plants because water evaporation and high heat are suppressed.

For example, if the thickness of the hollow plate-like body 1 is 10 cm, the combined weight of the water-containing and water-retaining base 6 is 100 to 130 kg / m ^{2. With} this weight, the radiation shielding rate is approximately 50%. It is estimated. This weight can be maintained permanently without being affected by the surrounding environment. Furthermore, the soil laminated on the upper surface is laminated with a lot of mineral fibers excellent in water retention, and depending on the thickness of the soil, for example, if it is 10 cm, it becomes about 140 kg in the soil water saturated state.

That is, the total weight of the weight of the lower hollow plate-like body 1 and the weight of the soil is 240 to 270 kg / m ² , and this load (mass) load structure is formed on the ground contaminated with radioactive substances. Since it is provided on the top surface, radiation shielding is possible approximately 75%, but the soil weight is not always constant because the plant consumes the water content of the soil. Therefore, the minimum load (mass) load of the soil weight is a fixed load of only the soil and the culvert plate when water content is set to 0. Therefore, if the soil weight is 50 kg, the hollow plate 1 A load obtained by adding a soil weight of 50 kg to a weight of 100 to 130 kg is a fixed load according to this configuration. That is, 150 to 180 kg is a fixed load. At this load, the radiation shielding rate is estimated to be approximately 60%. However, this numerical value is a numerical value based on a soil water content of 0, and it is more appropriate to obtain the radiation shielding rate by estimating that the water content weight is added to this numerical value. As described above, this configuration is useful for radiation shielding.
In this configuration, the activated carbon adhering water-permeable sheet 17 is laminated, but since this activated carbon is an ultrafine activated carbon having a particle size of 990 μm or less, it is possible to sufficiently expect the effect of adsorbing radioactive substances, and, Zeolite, which is a porous desiccant and also a fertilizer, may be mixed with the soil. The activated carbon and the desiccant are expected to adsorb the radioactive material released from the lowermost ground contaminated with the radioactive material when passing through the hollow plate-like body 1 and the hollow culvert plate 22. .

FIG. 18 shows a hollow plate shape in which a hollow plate-like body 1 corresponding to a specific example of the configuration of the third invention is provided on the upper surface of the ground 49 contaminated with the lowermost radioactive substance, and the water retention substrate 6 is filled. Activated carbon-permeable water-permeable sheet 17 is laminated on the upper surface of the surface thin plate in which band-shaped through-holes 11 are formed in body 1, soil 33 containing a large amount of mineral fibers is formed on the upper surface, and turf grass 57 is planted on the uppermost surface. A structure is shown. This cross-sectional view shows that the ultrafine activated carbon adhering water-permeable sheet 17 having a particle size of 990 μm or less is permeated so that the rain 92 reaches the soil from the lawn surface, and falls into the hollow plate-like body 1. It shows a state in which the water is drained as surplus water 58 from a portion where the partially closed end portion is not closed and is immersed in the hollow underdrain plate 22. An edge material 55 is provided on the side surface of the soil 33. In this configuration, the effect of reducing the transmission of radiation emitted from the ground contaminated with radioactive material is obtained, and drainage treatment in the event of heavy rain is facilitated. This is useful for rehabilitation and greening. It is also useful because it enables crop production on farmland in areas contaminated with radioactive materials.

In the configuration shown in the cross-sectional view of FIG. 19, the hollow plate-like body 1 corresponding to a specific example of the configuration of the third invention is provided on the upper surface of the ground 49 contaminated with the lowermost radioactive material. A plurality of strip-shaped through holes 11 are formed in the surface thin plate 2 of the hollow plate-like body 1. A hollow culvert plate 22 having a back thin plate 3 formed with a plurality of strip-shaped through holes 11 and a front thin plate 2 formed with a plurality of strip-shaped through holes 11 is laminated on the upper surface. On the upper surface of the hollow culvert plate 22, an ultrafine activated carbon-adhered permeable sheet 17 having a particle size of 990 μm or less is laminated. On the upper surface, a soil 33 containing a lot of mineral fibers is formed. Turf grass 57 is planted in the soil 33. The rain water 92 passes through the ultrafine-grain activated carbon-attached water-permeable sheet 17 having a particle size of 990 μm or less so as to reach the soil from the lawn surface, and falls into the hollow undergrowth plate 22 and the hollow plate-like body 1 laminated in two layers. The surplus water from the soil 33 is contained in the hollow plate 1. The hollow undercover 22 of the two layers is a hollow undercover corresponding to a specific example of the structure of the fourteenth aspect of the invention, and the peripheral edge of the hollow undercover 22 is all closed. It has become a structure. Therefore, water such as rainfall 92 penetrates into the soil 33, and surplus water that cannot be retained by the soil 33 is further stored in the hollow culvert plate 22 present in the lower layer. And when the hollow culvert plate 22 becomes saturated with water storage, it is drained as surplus water from the strip-shaped through hole 11 formed in the thin plate 2 to the outside of the hollow culvert plate 22 beyond the ribs of the hollow culvert plate 22. Although the structure is such that the amount of water stored in the hollow culvert plate 22 is once retained.

Further, the amount of water stored in the hollow culvert plate 22 can be calculated from the hollow volume of the hollow culvert plate 22. That is, if the size of the hollow culvert plate 22 is 10 cm and the width of the rib 4 excluding the thickness of the front thin plate 2 and the back thin plate 3 is 10 cm and the width is 1 m square, the hollow culvert plate has a size of 0.1 m ^3. Water can be retained. That is, since the weight of this water is 100 kg / m ² , the transmission of radiation can be reduced to about 50%. According to this configuration, since the hollow culvert plate 2 is stacked in two layers, the transmission of radiation can be reduced to about 25%. In addition, when the soil moisture content is added to the water retention weight retained in the hollow undergrowth plate, it is considered that the transmission of radiation is 20% or less. This configuration, which enables plant cultivation and reduced radiation transmission, is useful for rehabilitating greenery in areas contaminated with radioactive materials. In addition, considering the selection of plant species that cannot reach the roots of the hollow undergrowth 22 and the thickness and water content of the soil 33, a plant with relatively low water consumption other than turfgrass is selected and applied to the soil 33. It is also preferable to plant. Of course, it is also useful for farmland in areas contaminated with radioactive materials.

FIG. 20 is a diagram showing an example of a configuration in which the radiation emission of the decontaminated material contaminated with the radioactive material is reduced and simultaneously green.
As shown in the sectional view of the upper figure (a), in this configuration, the hollow plate-like body 1 is provided in the lowermost layer, and the hollow culvert plate 22 is provided on the upper surface thereof. A radiation emission waste 59 (a plurality of bags) is piled up in the inner area from the peripheral edge of the flat surface of the hollow undercover 22. The hollow plate-like body 1 is provided on the upper surface of the radiation emission waste 59 placed in a pile, and the hollow culvert plate 22 is laminated on the upper surface. Furthermore, an ultrafine activated carbon-adhered water-permeable sheet 17 having a particle size of 990 μm or less is laid on the upper surface of the hollow undercover 22. On the upper surface, a soil 33 containing a lot of rock wool made of blast furnace slag is formed. The created soil 33 is sown with turfgrass 57 seeds to form a lawn. Or plants other than turfgrass 57 are planted in soil 33 and greening is completed. The greening of the upper surface of the radiation emitting waste can reduce or completely shield the radiation emission and prevent the radiation emitting waste from being exposed to the general public. That is, the storage location can be returned to a safe natural environment. In order to prevent the surface of the green space from being adversely affected by the radiation emitting waste 59, the green space on the upper surface of the radiation emitting waste should be changed in consideration of the weight of the soil 33 and the weight of the hollow plate-like body 1 having a water-containing function. It is good to carry out.

In the configuration of this figure, the substrate weight on the upper surface of the radiation emission waste is designed to be 250 kg to 300 kg per square meter. This load is estimated to shield approximately 90% of the dose from radiation-emitting waste. In addition, because this rock has a lot of rock wool fibers in the soil, it has a feature that the soil is integrated and suppresses the occurrence of the separation phenomenon, and prevents the soil from collapsing and has good drainage. In addition, since the hollow culvert plate 22 that is not destroyed by the load of a large vehicle is provided in the lower layer, it can withstand the load of soil that becomes heavy due to moisture, and excess water is also drained from the drainage channel. Compared with the embankment green land with a large gradient angle only for general customer soil, the green land surface is hardly collapsed or washed away by heavy rain, etc., so this structure of the green space is useful.
Further, FIG. (A) is a cross-sectional view showing a state in which the radiation emission waste is placed in a pile, but this configuration is also useful for a storage place where the radiation emission waste is not piled up. In this green space configuration, it is also preferable to provide the lowermost hollow plate-like body 1 on the upper surface such as the ground contaminated with radioactive substances.

The intermediate view (b) is a cross-sectional view showing a form related to the upper view (a). In this configuration, the hollow culvert plate 22 is connected to the through hole of the drain pipe 23 in which at least one belt-like through hole is formed, and is installed on the upper surface of the soil 33. The radiation emission waste 59 (a plurality of bags) is piled up in a region on the inner side from the periphery of the upper surface of the installed hollow culvert plate 22. The hollow plate-like body 1 is provided on the upper surface of the radiation emission waste 59 placed in a pile, and the hollow culvert plate 22 is laminated on the upper surface. Furthermore, an ultrafine activated carbon-adhered water-permeable sheet 17 having a particle size of 990 μm or less is laid on the upper surface of the hollow culvert plate 22. On the upper surface, a soil 33 containing a lot of mineral fibers is created. The created soil 33 is seeded with turfgrass 57 to form a lawn, or plants other than turfgrass 57 are planted in the soil to complete greening. Since the band-shaped through-hole forming drain pipe 23 is provided in this configuration, drainage of rainwater or the like from the green ground to the lower layer soil 33 and further from the hollow underdrain plate 22 to the band-shaped through-hole forming drain pipe 23 becomes smoother. It is preferable because the drainage water is guided to the drainage pipe connected to the belt-shaped through-hole forming drainage pipe 23.

The lower figure (c) is a cross-sectional view showing the form related to the upper figure (a) and the intermediate figure (b). In this configuration, the hollow culvert plate 22 is connected to the through hole of the drain pipe 23 in which at least one band-shaped through hole is formed, and is installed on the upper surface of the radioactive material contaminated ground 48. The radiation emission waste 59 (a plurality of bags) is piled up in a region on the inner side from the periphery of the upper surface of the installed hollow culvert plate 22. The hollow plate-like body 1 is provided on the upper surface of the radiation emission waste 59 placed in a pile, and the hollow culvert plate 22 is laminated on the upper surface. Furthermore, an ultrafine activated carbon-adhered water-permeable sheet 17 having a particle size of 990 μm or less is laid on the upper surface of the hollow culvert plate 22. On the upper surface, a soil 33 containing a lot of mineral fibers is created. The created soil 33 is planted with turfgrass seeds to form a lawn, or plants other than turfgrass are planted in the soil to complete greening. This configuration makes it possible to greenen the upper surface of the radioactive material contaminated ground 48 and further reduce the transmission of radiation emitted from the ground and waste, and in addition to fixing radioactive materials contained in the land.

An upper diagram (a) of FIG. 21 is a perspective view showing an example of the configuration of the twenty-first invention. Reference numeral 17 is a polyester spunbonded non-woven fabric having a width of 45 cm and a length of 158 cm (weight per unit area: 40 g / m 2). This is a polyester spunbonded nonwoven fabric (weight per unit area 80 g / m 2). The two nonwoven fabrics 17 and 17 are heat-welded so that the size of the lattice 99 is 60 mm in length and 36 mm in width. The number of lattices is 230, and 20 g of zeolite having a particle size of 990 μm or less is enclosed in each lattice.
A polymer water-absorbing resin and ultrafine activated carbon having a particle size of 990 μm or less may be mixed with zeolite in this lattice, or zeolite may be replaced with a polymer water-absorbing resin and ultrafine activated carbon having a particle size of 990 μm or less. Good.

Moreover, the middle figure (b) is also a top view showing an example of the structure of the forty-first invention. The upper surface turtle-shaped lattice 99 is a biodegradable sheet 87 having a width of 200 cm and a length of 200 cm. Plant seeds 34 are bonded together with the biodegradable sheet 87 and the wafer sheet 88 at a low temperature between the sheet 87 and the wafer sheet 88 on the back surface. On the lower surface, there is a sheet 17 attached with ultrafine activated carbon having a particle size of 990 μm or less. The nonwoven fabric 17 and the sheets 87 and 88 are heat-welded so that the size of the lattice 99 is 300 mm in length and 300 mm in width. As shown in the sectional view of FIG. (C), 200 g of zeolite 90 having a particle size of 990 μm or less, 10 g of the polymer water-absorbent resin 100 of the water-retaining substrate 6, and 500 g of rockwool granular cotton 101, It is enclosed.
The number of lattices in which the biodegradable sheet 87 having the seeds 34, the wafer sheet 88 and the nonwoven fabric 17 are bonded is 36. The weight of the constituent sheet is 29 kg in the dry state, and 54 kg / m ² in the water-containing saturated state. This dry weight has no problem in workability. Further, the sheet can be cut into a plurality of sheets for use.
This sheet constitutes a water-retaining substrate that combines the shielding effect of radioactive substances present in forests, highway slopes, and the like with water content and porous materials that are useful for fixing, thereby steadily germinating plant seeds. It is preferable because it can be grown.
In addition, the biodegradable sheet 87 and the wafer sheet 88 have a high rate of decomposition by microorganisms and are dissolved in water and converted into soil, so that they do not adversely affect the environment.

The configuration of FIG. 22 is related to FIG. As shown in the cross-sectional view of the upper diagram (a), in this configuration, the nonwoven fabric sheet 28 having a resin fiber amount of 12 to 20 g / m ² is on the upper surface, and ultrafine activated carbon having a particle size of 990 μm or less is attached. Sheet 17 is at the bottom. The nonwoven fabric sheet 28 and the lowermost sheet 17 are sewn at the joint portion 29 to form a bag body 32. From the lower layer inside the bag body 32, the soil 33 mainly composed of humus is filled, and the water retaining substrate 6 composed mainly of rock wool is laminated on the upper surface, and the humus is mainly composed on the upper surface. The soil 33 is laminated, and a sheet 17 to which ultrafine activated carbon having a particle size of 990 μm or less is attached is further laminated on the upper surface. A plurality of plant seeds 34 are placed on the upper surface of the sheet 17 in several places.
The bag body 32 has a width of 70 cm, a width of 55 cm, and a thickness of 25 cm, and its weight is 21 kg in a dry matter state. And if water is poured into the nonwoven fabric sheet 17 on the upper surface of this bag body, the water retaining substrate 6 and the soil 33 will contain water. The weight of the water-containing bag is 120 kg in a saturated state of water. It is estimated that placing this bag on green areas contaminated with radioactive materials, the ground of forests, and the top of deciduous leaves will reduce the radiation shielding rate to 50%, and the seeds of the bag will grow. This is also preferable as it is a green restoration.

Moreover, in the structural example shown to the perspective view of a middle stage figure (b), the notch 36 is formed in the nonwoven fabric sheet 28 of the upper surface of the bag body 32 of the upper figure (a) with cutters, such as a cutter knife. In the figure, a portion where the nonwoven fabric sheet 28 is cut out and a joint portion 29 which is sewn with a sewing machine or the like are shown. When plant seedlings are planted in the notches 36, the seeds placed in the bag body 32 grow and become grassland, and trees can be grown together in the grassland. For this reason, this structure is suitable for restoration of a variety of green spaces.
In addition, when the seedling planted in the bag body 32 grows, the root penetrates the activated carbon adhesion sheet on the lower surface of the bag body 32 and extends to the lower layer of the ground, and the above-ground part grows along with the elongation of the root.
The structure of the bag body 32 is characterized in that it has a thickness, and since there is sufficient ventilation and drainage from the peripheral side wall having the thickness, root rot due to a large amount of water content does not occur.

In addition to soil elements, carbon, oxygen, and nutrients where plant roots grow, mineral fiber soils are not affected by microbial degradation and maintain moisture content for many years. It is preferable to place this bag 32 on the upper surface of the leaf fall surface.
The planting bag body 32 having this configuration can also be used on road slopes that are not contaminated with radioactive materials, green spaces, forest grounds, and top surfaces of deciduous surfaces.
Moreover, the lower figure (c) is a perspective view of the structure which formed the planting hole 13 by replacing the bag body 32 of the upper figure (a) and the middle figure (b) with the packaging body 35. FIG. In addition, this package 35 is packaged with a nonwoven fabric sheet having a resin fiber amount of 12 to 20 g / m ² . The closing part of the package 35 may be closed with a known adhesive, double-sided tape, single-sided tape, or the like. The package base material having this configuration is preferable because it can be inexpensive.

FIGS. 23A and 23B are cross-sectional views showing an example of the bag body 32 related to FIG. Plant seeds 34 are placed between the nonwoven fabric sheet 28 and the soil 33, which are the material of the bag. A water retaining substrate 6 is laminated on the lower layer of the soil. This water retaining substrate is a rock wool fiber granular cotton 101 and has a thickness of 15 cm. And the nonwoven fabric sheet 28 of a bag is shown in the lower layer of a water retention base material.
In the figure shown in (b), plant seeds 34 are sandwiched between two non-woven sheets 28 that are the material of the bag. And the through-hole 13 for planting a plant seedling is opened in the two nonwoven fabric sheets. The lower layer is laminated with soil that is useful for germinating plant seeds. The layer below the soil layer is laminated with a water retention substrate 6 for storing a lot of rainfall. This water retention substrate is a rock wool fiber granular cotton 101, and its thickness is 20 cm. And the nonwoven fabric sheet 28 of a bag is shown in the lower layer of a water retention base material. This bag has a width of 50 cm, a width of 50 cm, a dry weight of 18 kg, and a water content of about 90 l.

That is, the weight of the bag body is 118 kg (water saturation). This weight is useful because it is estimated that the radiation shielding rate is suppressed to 50%. Moreover, since the nonwoven fabric sheet 28 of an upper surface layer is two layers, it is preferable from the water content evaporation amount of a water retention base material being also suppressed. In addition, since this bag can implement | achieve cost reduction, it can provide widely and is preferable. In addition, the feature of this configuration is useful for restoring “green” because the seeds and seedlings of plants can be grown. Further, an ultrafine-grained activated carbon adhering nonwoven fabric sheet having a particle size of 990 μm or less is laid on the place where the bag body 32 is placed on a soil contaminated with radioactive substances, and an ultrafine-zeolite adhering kneaded paper sheet having a particle size of 990 μm or less is provided. It is preferable to select a method of laying or sowing either ultrafine activated carbon having a particle size of 990 μm or less, a mixture of zeolite, ultrafine activated carbon having a particle size of 990 μm or less, or zeolite. By this method, it can be predicted that activated carbon and zeolite will adsorb the radioactive material, and that the radioactive material adsorbed by the moisture content of the bag body will be prevented from being scattered and separated by water, and a radiation shielding effect can also be obtained. It is useful because it can. In addition, if the method of placing the culvert plate of the ninth invention at the place where the activated carbon and zeolite are seeded and arranging the bag body 32 on the upper surface thereof is adopted, the fixing effect of the radioactive material and the radiation shielding effect are further enhanced. preferable. In addition, the bag 32 formed by laminating and laminating the culvert plate or plate of the ninth invention made of a thermoplastic resin having a thickness of 1 mm to 15 mm between the water retention substrate 6 and the nonwoven fabric sheet 28 was contaminated with a radioactive substance. Placement on land is also useful as another embodiment.

In the configuration shown in the top perspective view of FIG. 24, the bag body 32 is formed by closing and welding the joint portion 29 at the peripheral portion of the resin fiber fabric 68 whose surface is woven unevenly and has water permeability. A water injection port 25 is provided at a part of the peripheral weld 18 at the peripheral edge, and a lid 8 for closing the water injection port after water injection is provided. The bag body 32 is filled with rock wool fibers made from blast furnace slag as a raw material. Rock wool is generally provided on the market for the purpose of heat insulation, and has a structure in which at least 95% of air essential for heat insulation exists in the volume of rock wool. That is, when water is poured into rock wool, it is contained in this void. Thus, for example, 1 m ³ of rock wool generally contains a single amount of water. Further, the fiber fabric of the bag body 32 is a fabric made of polyethylene, and the shape of the bag fabric is woven in an uneven shape. If seeds of plants mixed with soil or sand are sown in this uneven shape, or seeds, stabilizers, curing materials, and fertilizers are mixed and sprayed with soil, the seeds are uneven and difficult to move. That is, the seeds are less likely to be washed away by precipitation, and the seeds can easily use the water contained in the water-holding base material filled in the gaps between the fibers of the bag body 32. Preferably, the bag body 32 is useful for greening. Further, since a large amount of rainfall permeates into the bag body 32 due to unevenness can be expected, this uneven fabric is preferable for collecting rainfall and water spray.

In addition, when the bag body 32 increases in weight by water injection or precipitation, the transmission of radiation can be reduced by the load. The bag body 32 has an average thickness of 10 cm, a width of 60 cm, and a width of 150 cm, and a water-containing saturated weight of about 120 kg. At this weight, the radiation transmittance is estimated to be about 50%, but in order to further reduce the transmittance, it is desirable to use a plurality of bags. This example is an example of a form for the purpose of shielding radioactivity and restoring greenery. If it is only used for radioactivity shielding, other water-retaining base materials instead of rock wool, which is good for growing plants, 32 may be filled.
Further, in the middle sectional view (b) and the lower sectional perspective view (c), the water retaining base material layer 6 is laminated from the lower layer inside the bag body 32, and the soil layer 33 is laminated on the upper surface layer, and the soil layer The structure which put the seed 34 of the plant between 33 and the back of the upper surface fabric 68 is shown. In the case of this configuration example, since the seed 34 is inside the bag body 32, it is not necessary to sow the seed at the site where it is used. This is preferable because it does not require seed sowing.

In the configuration shown in FIG. 25, the drainage pipe 23 is embedded in a part of the contaminated soil 93, and a belt-like through hole is opened on the upper surface of the drainage pipe 23, and the end of the hollow culvert plate 22 is formed in the opening. Leave the back thin plate, and insert the bent end by cutting the front thin plate and the rib. The left and right hollow culvert plates 22 are connected to the drainage pipe 23, and the hollow plate 21 is provided at a position on the upper surface where excess water of the rain 92 falls from the drainage channel 43 to the drainage pipe 23. And the water-permeable sheet 17 to which activated carbon was attached was laid on the upper surface of the hollow plate 21 and the upper and lower hollow culvert plates 22, and the soil 33 was created on the upper surface of the sheet, and the plant 95 was planted. Yes. In addition, a water permeable sheet 17 to which activated carbon is attached is bonded to the outer surface of the drain pipe 23 for the purpose of preventing the radioactive material from entering the drain pipe 23. The upper figure (a) is a sectional view of this configuration.

According to this configuration, since the hollow culvert plate 22 is embedded in a planar shape, even if there is a rainfall amount such as guerrilla heavy rain that falls in a short time, the water surface is not stagnated. Smoothly drain excess water from the soil. For this reason, this configuration is useful for urban infrastructure development because it can prevent the puddle phenomenon on the ground surface.
And, it is possible to reduce the transmission of the radiation radiated from the soil contaminated with the radioactive material on the lower surface of the hollow undercover 22 to the ground due to the load of the soil having water retention and the load of the undercover of the hollow undercover. Is even more useful. In addition, the lower figure (b) is a perspective view which shows a mode that the hollow culvert board 22 with which the water-permeable sheet 17 with which the activated carbon was adhered was bonded on the surface is inserted vertically into the drain pipe.

  According to this structure, the radioactive substance which floats in the air, the radioactive substance adhering to the rain, and other pollutants can be adsorbed. Moreover, since the radiation of a radioactive substance permeate | transmits the back surface of the hollow culvert board 22 can be reduced by the adsorption effect, it is useful. Moreover, in this structure, the belt-like through-holes 11 are formed, and in some places of the natural or flame-retardant sheet 17 provided on the upper surface of the hollow undercover plate 22 to which the water-permeable sheet 17 to which the activated carbon is attached is bonded. The sheet 17 is formed on the upper surface of the hollow culvert plate 22 using a fixing member, by providing a cutout portion in a lateral direction or an oblique direction, leaving a region filled with soil in a part below the cutout portion. When the plant is planted by pasting and filling the notch with soil, the plant grows due to the drainage effect and aeration effect of the hollow undergrowth plate 22, the adsorption effect of activated carbon on the gases released from the roots Therefore, it is useful including the effect of adsorbing contaminants described above. In this configuration for planting a plant, it is more preferable that the water-permeable sheet 17 to which the activated carbon is attached is bonded to the back surface where the band-shaped through-holes 11 are not formed.

FIG. 26 is a perspective view showing a configuration example in which the irrigation pipe 15 is provided between the front thin plate 2 and the back thin plate 3 on the upper surface of the hollow undercover plate 22 in the drawing. In this figure, the form before the cover 8 which covers the upper part of the irrigation pipe | tube 15 is provided in the upper part of the surface thin plate 2 and the back thin plate 3 is shown. This configuration is such that water discharged from the irrigation pipe 15 does not leak to the outside. Further, the water discharged from the irrigation pipe 15 passes through each of the belt-like through holes 11 formed in the hollow culvert plate 22 at regular intervals, and falls to cover the surface of the substantially hollow culvert plate 22. To do. This configuration, in which water is distributed in a plane, falls in preparation for when the amount of water contained in the water retention base is reduced, and is also for facilitating water injection into the water retention base. Useful. The wall structure greening having this configuration is useful because it can supplement the water consumed by plants when rain cannot be expected.

In the configuration shown in the cross-sectional view of FIG. 27, the water-containing hollow plate 1 having no through-holes is provided on the back surface, and the hollow undercover plate 22, activated carbon adhering sheet 17, soil 33, and water-repellent heat insulating material are provided on the front side surface. Forty-two rock wool plates are provided on each side. On the front surface of the rock wool plate, a non-combustible material 41 having a through hole 12 for planting the plant is provided at the same position as the through hole 12 of the rock wool plate. Further, in order to fix the base material of each layer, the bolts that are the fixing members 16 are communicated with the water-containing hollow plate 1 on the back side from the non-combustible material 41 arranged on the forefront, respectively, with a washer and a nut. Attach to the location of.
The hollow plate 21 is provided between the activated carbon adhering sheet 17 and the water repellent heat insulating material 42, and the base material of each layer is fixed using a washer and a nut through the hollow of the hollow plate 21 by a bolt of a fixing member. Has been.
The greening body having a wall structure according to this configuration can reduce the transmission of radiation due to the water content of the water-containing hollow body 1, the weight of the hollow culvert plate 22, and the weight of the soil containing water. In addition, since the activated carbon adhesion sheet 17 is provided, it is also useful for shielding radioactive substances. In addition, activated carbon is mixed in the soil. Moreover, since the color pigment is added to the hollow undercover plate 22 and the water-containing hollow plate-like body 1, it is useful because a shielding effect of the radioactive substance can be desired.

FIG. 28 is a cross-sectional view of a configuration in which the hollow undercover plate 22 shown in FIG. 27 is omitted.
On the soil side surface of the water-containing hollow plate 1 shown in this configuration, a base material having a belt-like through hole 11 is selected. For this reason, this structure is preferable because it constitutes a soil structure that requires drainage and air permeability, which are indispensable for growing plants.

FIG. 29 is an exploded perspective view showing a part (a) shown in FIG. In this partial view, as described with reference to FIG. 27, a plurality of through holes 12 for planting are opened in a non-combustible material 41 placed on the front surface. In this example, five planting through holes are provided, but the number is not limited to this. Moreover, although the fixing member 16 is provided in four places, this number and position may be arbitrary. And the through-hole 12 for planting is opened also in the heat insulating material 42 put on a back surface in the same position as a front surface.

Invented is a radioactive gas ventilation adsorption pipe in which the gaps at both ends are closed with a lid or the like and a bolt, nut, washer or the like as a closing member. The size of the radioactive gas ventilation adsorption pipe is preferably designed in consideration of the gas adsorption capacity of activated carbon, the amount of gas to be vented inside the pipe, the adsorption rate, the mass of activated carbon, and the like. When the radioactive gas ventilation adsorption pipe is put into practical use, it is preferable to provide an opening provided by connecting a pipe for venting gas to the lid. This pipe structure is useful for adsorbing various types of gases and is useful because it can be manufactured at low cost. Even in the gas adsorption described above, water may be added to the fiber molded body having no water repellency which is the main raw material of the blast furnace slag in the pipe. As an advantage of water content, activated carbon is accompanied by heat generation due to the adsorption phenomenon. Since it can be predicted that it is theoretically possible to cool and relax the heat of adsorption related to the calorific value, water content is preferable.

In addition, after a lid that matches the size of both ends of the radioactive gas ventilation adsorption pipe is prepared, and the gap is filled with any one of the water-retaining base materials described in the 71st, 72nd, or 74th inventions An embodiment in which a substance contaminated with a radioactive substance is housed inside the inner container and then sealed by providing lids at both ends is also useful for reducing the radiation of the radioactive substance.

In addition, it is also preferable that a water-containing inlet is provided in the outer container (pipe) to inject water into the water retaining substrate.

In the configuration shown in the cross-sectional view of FIG. 35, a resin bag in which a radioactive substance contaminant 71 that is contaminated with a radioactive substance and emits radiation is contained inside an outer container 65 that is formed into a cylindrical shape with concrete. A body 68 (radiation emission storage bag) is placed on a hollow pedestal 67 formed by forming a hollow resin plate into a ring shape. Under the hollow pedestal 67 and the outer container 65, a hollow resin plate is provided as an outer and inner lower pedestal 73, and a resin loading platform 75 is disposed below the hollow resin plate. Further, the gap between the entire outer container 65 and the pedestal 73 and the bag body 68 inside thereof forms a water-containing space including the inner region of the hollow pedestal 67 formed in an annular band, and this water-containing space. In addition, the water-retaining substrate 6 is filled without any gaps. A lid 69 is placed thereon.
The cross-sectional thickness of the water retention substrate 6 disposed in the water-containing space is 40 cm on average. The water-retaining substrate 6 is a water-retaining substrate in which rock wool granular cotton and ultrafine activated carbon having a particle size of 990 μm or less are mixed, and its weight when saturated with water is about 280 kg / m ² . With this weight (mass), it is possible to prevent the radiation emitted from the radioactive substance 71 stored in the radioactive substance storage space 70 from passing through the outer container 65. The reason why activated carbon, which is generally known for its physical and chemical adsorption functions, is added to the water retention substrate 6 is that carbon is at least useful for shielding radiation. Then, it was speculated that among the activated carbons, ultrafine activated carbon having a particle size of 990 μm or less was effective in reducing the dose. A material having an adsorption function may be selected from the microscopic carbon containing activated carbon and mixed with the water retention base material, and it is also preferable to increase the mixing ratio of the activated carbon.

This hollow pedestal is a hollow plate having a plurality of plate-like ribs between the front and rear thin plates, and a water retaining substrate 6 containing activated carbon is filled in a space surrounded by the front and rear thin plates and the plate-like ribs. Thus, it is useful for reducing transmission of radiation emitted downward from the radioactive substance 71 accommodated in the radioactive substance accommodating space 70 when it is hydrated. A resin-made hollow plate having weather resistance is preferable because it is lightweight and inexpensive.
Since the thickness of the water retaining substrate of the large outer container and the inner container can be 50 cm or more on average, the radiation emitted from the radioactive substance 71 stored in the radioactive substance storage space 70 after hydration is contained in the outer container 65. Can be prevented. That is, the basis for preventing permeation is that when a water-retaining base material of a dry matter designed with a thickness of 50 cm is hydrated, the total load of the water-retaining base material and the water-containing saturation load is 600 kg. Also, using any one of the radiation transmission reducing constituent substrates of the first to fifteenth inventions having the fitting of the sixteenth invention shown in FIG. 16 and the joint of the seventeenth invention shown in FIG.

Moreover, the shape of the container of the outer side and an inner side may be a container of the shape where the wall of the both ends of the U-shaped side groove currently generally used was closed. The material forming the lid 69 is not limited to metal, concrete, resin, or the like. It is also preferable to configure a plurality of water retention bases for the outer container and the inner container. In order to produce a large lid, it is also preferable to divide the lid and connect it in the same manner as the divided outer inner container wall 111. Further, it is preferable to provide at least one water inlet in the large lid. Further, the shape of the lid 69 may be anything that matches the shape of the outer container 65. The size of the radiation transmission reducing container is a moisture content that is a gap between the radioactive substance contained in the bag body 68 or a substance contaminated with the radioactive substance and the bag body 68 and the outer container 65 and the pedestal 73. It may be arbitrarily determined in consideration of the size matching the space.

The shapes of the outer container 65, the inner container 66, and the container lid 69 are merely examples, and are not limited, and any shape such as a polygon, a circle, or an ellipse may be selected. In addition, the shape of the container lid 69 may be anything that matches the shape of the outer container 65. The size of the radiation transmission reducing container is determined by the capacity of the radioactive substance stored inside the inner container, the substance contaminated with the radioactive substance, and the gap between the inner container 66 and the inner container lower pedestal 72 and the outer container 65. What is necessary is just to determine arbitrarily considering the size matched with a certain water-containing space.

The cross-sectional thickness of the water retaining substrate 6 in the gap between the outer container 65 and the inner container 66 and between the outer container 65 and the pedestal 72 is 40 cm.

This weight can prevent the radiation emitted from the radioactive substance stored in the radioactive substance storage space from passing through the outer container. Moreover, the cross-sectional thickness of the water retention substrate 6 provided on the container lid 69 is 35 cm / m ² . The combined weight of the water retaining substrate 6 having this thickness and the water content saturation amount is about 240 kg / m ² . This weight is useful because the radiation emitted from the radioactive substance stored in the radioactive substance storage space 70 can be prevented from passing through the container lid 69. The reason why activated carbon, which is generally known to have a physical adsorption function, is added to the water retention substrate 6 is that carbon is at least useful for shielding radiation. Of the activated carbons, ultrafine activated carbon having a particle size of 990 μm or less is expected to be particularly effective for shielding the dose.

Furthermore, a plurality of radioactive substance contaminant storage bags can be stacked in this container, and a form in which the radiation transmission reducing container shown in each figure is laid down and a lid is provided at both ends is also preferable. In addition, when using a radiation transmission reducing container lying on its side, it is preferable to provide a water inlet on the upper surface of the outer container. The example shown in FIG. 61, which is a perspective view, is recommended. Further, if the outer container is cylindrical, it can be expected to move from side to side, so it is recommended to provide a pedestal or the like for fixing the outer container.

In the configuration of FIG. 41, the water retaining substrate 6 is filled inside a block-like body 24 which is a kind of container, and the water filling port 25 provided for pouring water into the water retaining substrate 6 is a block. It is formed into a body 24. The water injection port 25 is provided with a lid, and the water injection port can be closed with the lid after the water injection to the water retaining substrate 6 is completed. Further, a configuration in which the block-like body 24 is stacked by providing a foundation like a concrete block wall is shown in FIG. As shown in the perspective view of FIG. (C), a concrete foundation 27 incorporating a reinforcing bar is provided on the ground from the ground, and another reinforcing bar 26 is tied to the reinforcing bar 26 incorporated in the concrete foundation 27 with a wire or the like. . Then, the reinforcing bars 26 are inserted into the hollow portions of the block-like body 24. Thus, the block-like body 24 piled up by the same construction method as that of the concrete block wall can be useful in a place where it is prevented from being collapsed and radiation shielding is required. Further, the weight of the block-like body 24 in the water-containing saturated state is 17 to 20 kg. That is, when this block-like body 24 becomes a wall structure, it is useful for shielding radiation. The cavities of the block-like body 24 are filled with mortar. Thereby, the load of the wall structure increases. Further, it is preferable that the block-like body 24 is made of a fiber reinforced plastic, or manufactured by a vinyl chloride resin molding or a polycarbonate resin molding because of good weather resistance and strength.
Further, the block-like body 24 is provided with a lid on the water injection port 25. FIG. 2B is a sectional view taken along the dotted line shown in FIG. As shown in this cross-sectional view, the chamber filled with the water retention substrate 6 is divided into three by the rib wall 4, and each of the chambers is filled with the water retention substrate 6. The rib wall 4 increases the strength of the block-like body 24. However, such a structure is an example, and the block-like body 24 is not limited to this structure.

The box body 37 shown in the development view is constructed, and the water-retaining substrate 6 is filled therein. According to this configuration, in the manufacturing stage of the hollow plate 21 in which polypropylene resin is used as a forming raw material, a black pigment is selected as the resin raw material as an additive in order to obtain weather resistance. And the aluminum foil is further bonded to the surface of the black hollow plate 21 which has a weather resistance, and the weather resistance is improved further. One through hole 12 is provided at the center of the hollow plate 21. This through-hole 12 is established for the purpose of water injection, and the through-hole-shaped hollow plate 21 that has been perforated with an electric tool is fitted into the hollowed-out portion when the water-holding substrate 6 is filled with water, and from above It is advisable to bond the punched portion and its peripheral surface with tape. Further, as shown in FIG. 2B, the hollow plate 21 is folded, and the closing member 10 to which the adhesive tape is bonded is attached between the side wall and the flat portion, whereby the box-shaped body 37 is obtained. .

Before the hollow plate 21 is formed in the box-shaped body 37, the water-retaining base material 6 filled in the bag 34 is placed in the box-shaped body 37, and the box-shaped body 37 is folded at each folding position. The upper surface end portion (joining portion 29) is adhered to the box-shaped body 37 with an adhesive tape.
Since the water contained in the water retaining substrate 6 inside the hollow plate 21 does not easily leak from the sealed hollow plate 21, it is useful as a radiation transmission reducing substrate. Further, the hollow plate 21 is preferable because the front thin plate, the back thin plate, and the rib are integrally formed, and can withstand an external pressure such as a load. In general, the finished color of a molded product using polypropylene resin as a molding material is translucent, so the effect of reducing the transmission of radiation cannot be expected, but the additive pigment is a dark color such as black, green, or blue. This is useful for reducing the transmission of radiation. Further, in this configuration, the box-shaped material for housing the water retaining substrate 6 is the hollow plate 21, but this is merely an example, and is not limited to the hollow plate 21. The number of through-holes 12 is configured, but this number may be plural. Moreover, the form which excluded the through-hole 21 may be sufficient. In addition to the adhesive tape that forms the box-shaped body 37, the box-shaped body 37 may be formed by joining a hollow plate by heat welding or rivets.

By integrating the water shield provided in the container, a gas phase state without movement can be maintained in the upper and lower structural layers of the integrated packing structure. In the middle layer, a structure that can hold a non-moving water layer is formed. That is, it is useful because it can be assumed that the invention reduces the transmission of radioactive material by the present invention that holds a gas cuboid having a slight water vapor and a water-containing layer having oxygen. In addition, a total load of 133 kg, which is a combination of the upper layer and lower layer impermeable body loads of 16 kg, the middle layer dry water retention base material load of 20 kg and the water content saturation load of 97 kg, is useful for increasing the permeation reduction rate of radioactive materials. The combined size of the three water shields is 60 cm wide, 90 cm wide, and 60 cm high. It is theoretically predicted that the transmittance of gamma rays, which are highly transmissive radiation, can be suppressed to about 50% when the weight of the water shielding bodies shown in the figure is 133 kg. Furthermore, it has a shielding element such as a gas phase layer, a heat insulating layer, and an insulating layer other than the shielding factor caused by the load, so it is estimated that the transmission of the gamma ray is suppressed more than the effect of reducing the transmission of the gamma ray caused by the general load. Is done.

Further, according to the configuration of the cross-sectional view shown in FIG. (C), the water shield disposed in the lower layer is the same as the water shield formed in the upper layer and the lower layer shown in the upper diagrams (a) and (b). However, a sheet 17 in which ultrafine activated carbon having a particle size of 990 μm or less is attached inside a rock wool molded cuboid in which mineral fibers are subjected to water repellent processing is arranged and provided in a planar shape.
Further, the water shield disposed in the upper layer is the same as the middle layer water shield shown in the upper diagrams (a) and (b). The two water shields are fixed and packed with dedicated wire clips, screw screws or the like for fixing the wire rope using a stainless steel wire rope as shown in the figure. The water shields may be individually attached to the surfaces of the water shields facing each other when fixed and packed with the wire rope, wire clips, screw screws, and the like, using an adhesive, a pressure sensitive adhesive, and a front and back adhesive tape. In addition, as another means for fixing the multi-layer impermeable body, one of the plate, the hollow plate, and the hollow culvert plate of the ninth invention is applied to the outer surface of the multi-layer impermeable body. It is preferable to form a unitary structure by using a fixing member that is made to lean. By selecting this fixing means, it is preferable that the transmission reduction effect of the radioactive substance of the ninth invention is synergistic and useful for increasing the transmission reduction rate of the radioactive substance of the invention.

Note that a total load of 125 kg, which is a combination of the lower layer water shield load 8 kg, the middle layer dry water retention substrate load 20 kg, and the hydrous saturation load 97 kg, is useful for increasing the permeation reduction rate of the radioactive substance. Further, it is theoretically predicted that the load due to the two-layer water shield structure in the figure can suppress the transmittance of gamma rays, which are highly transmissive radiation, to about 50%. In addition, since the shielding composite elements such as the gas phase layer, heat insulation layer, insulation layer, and carbon layer other than the shielding factor caused by the load have gamma ray transmission more than the gamma ray transmission reduction effect caused by the general load. I guess that.

When the vapor phase structure according to the 87th invention is selected and replaced with a vapor phase body or a liquid phase body packaged with the water shielding sheet of the invention or packed with a bag made of the water shielding sheet, the radioactive material This is preferable because it is thought that the effect of reducing the permeation of substances is increased.

Moreover, the material which comprises is not specifically limited, For example, the bag body which consists of a waterproofing sheet for packaging and a waterproofing sheet, a rubber-cloth cloth sheet | seat formed by crimping | bonding fluororubber and an aramid fiber base fabric, fluorine Rubberized cloth sheet made by press-bonding rubber, aramid fiber base fabric and aluminum foil base fabric, glass fiber fabric, aluminum foil, aluminum fluororesin sheet formed by pressing aluminum foil base fabric and fluororesin film, rubber and aluminum Rubberized cloth glass fiber fabric formed by pressure bonding a foil base cloth, a rubberized cloth sheet formed by pressure bonding a nylon base cloth and rubber, a rubber cloth sheet formed by pressure bonding a nylon base cloth, a thermoplastic polyurethane elastomer, and rubber, Rubber base cloth sheet made by pressure-bonding polyester base cloth, thermoplastic polyurethane elastomer and rubber, rubber sheet made by pressure-bonding aramid fiber and silicon rubber It is recommended to select one of a stretched sheet, a rubber base sheet formed by pressure-bonding a polyester base cloth and polyethylene rubber or chloroprene rubber, and a polyethylene resin sheet. The present invention in a form of overlapping is also preferable.
The shape of the present invention may be selected from a method of manufacturing and stacking arbitrary shapes such as a cube, a rectangular parallelepiped, a triangular pyramid, a quadrangular pyramid, a cylinder, a disk, and a plate.
