Description

[Detailed Description of the Invention] A. INDUSTRIAL APPLICATION FIELD The present invention relates to equipment for collecting and utilizing rainwater, etc. B. Conventional technology (B1) Permeable pavements such as permeable concrete, permeable asphalt, and sand grains hardened with resin have been put into practical use. The water that permeated through the pipes seeped underground. (B2) Conventional rainwater collection equipment collects water that falls on the ground or roofs into water collection ditches, water tanks, etc.

(B3) In cultivation agriculture, farm roads (farming paths) are generally used.
and agricultural waterways (ditches or pipes) are required. C. Problem to be Solved by the Invention (CI) In the Bl section above, 81F could not be used for household water, agricultural water, fire prevention water, etc. (C2) Paragraph 82 includes garbage, sediment, etc., and if you want to obtain clean water, separate facilities such as filtering, de-sinking, and settling ponds are required, and the garbage, sediment, etc. collected by these must be disposed of. It was necessary to either remove it or return it to the place where it occurred. In addition, on the ground surface, during and immediately after rainfall, walking was likely to be difficult due to puddles and slipping. In addition, a separate site for water collection facilities was required from the rainfall area. <C3> In the above item 83, land was required for each of the farm roads and waterways, and a correspondingly larger land was required. (C4) For fire prevention reasons, it is ideal to install fire prevention water tanks all around important buildings, but in the past, it has been difficult to install fire prevention water tanks in areas other than specific hidden areas for reasons of easy access and aesthetics. [C5] With conventional rainwater collection equipment, if the collected rainwater is stored for several days, microorganisms and algae will grow in the water, which will cause the water intake pump and intake pipes to become clogged, and the collected water will not be purified. It was difficult to use it as water. (C6) Rainwater is effective for planting crops in farmlands, etc. during and immediately after rainfall, but it continues to damage the soil in planting areas, such as farmlands, even after several days after rainfall. It has been difficult to automatically maintain an appropriate moist state. D.

and a relay pipe that is bent and penetrates the wall of the stand and is introduced into the water collection groove material or the water storage tank. Here, in the highly water permeable ceramic pavement board, the diameter is 0.
．． Dense ceramic substrates manufactured from raw materials containing 60% by weight or more of inorganic powder of 1 mm or less have greater fracture resistance even though they are thinner than JIS sidewalk concrete slabs.
Most of the breaking load is borne by this, and the diameter is 2 mm to 7 m.
A porous ceramic base made from a raw material containing 50% by weight or more of inorganic coarse particles of 50% by weight has stable water permeability over a long period of time, and by integrally molding these two bases, it is thinner and lighter than JIS sidewalk concrete slabs, and , it is possible to obtain a pavement board with stable water permeability over a long period of time. As described above, the present invention installs a highly permeable paving board on the top surface of a water collection lubricant or a water storage tank, and collects rainwater, melted snow, etc. at the place where it falls and collects garbage. Relating to equipment for filtering soil, etc., collecting it in water catchment ditches or water storage tanks, and using it for household water, agricultural water, etc. As a highly water permeable ceramic pavement board, for example, one of the applicants of the present invention developed the patent application No. 63-262406
The surface is porous, dense and beautiful, has high strength to withstand walking and vehicular traffic, and has a water permeability of ordinary water permeable pavement materials, as shown in No. 1 (see the Examples section for details). (1
Use paving boards that have a water permeability several times higher than 0-2 cm/sec. The underside of these high-strength, highly permeable pavement plates is made of concrete and steel. By installing water catchment grooves or water storage tanks made of impermeable materials such as asphalt and stone, rain, melted snow, and other precipitation that flows onto the paving slabs, or sprinkled water, can be removed.
Almost the entire amount of car wash water, etc. can be received in the gutter or water tank without solids or sediment. The received water is collected and used through intake pipes installed in ditches or at appropriate locations in the water tank, depending on the purpose.

In addition, in order to prevent excess water from being received in the gutter or water tank, weirs with a height lower than the bottom surface of the permeable paving plates are installed at one or more locations, and by connecting to drains, sewer pipes, rainwater ditches, etc. Prevents water from overflowing onto the top surface of permeable pavement boards. By installing rainwater collection equipment that combines highly permeable paving boards and groove materials or water storage tanks around commercial buildings or on approaches from gates to entrances of general houses, balconies, garden passages, etc. The upper surface is easy to pass during and after rain, and can be used as a beautiful passage. Furthermore, large amounts of precipitation can be collected by directing rainwater from roofs and highways to such rainwater collection equipment via eaves gutters and vertical gutters. Since the collected water does not contain solid matter such as sand and garbage, it can be pumped up as needed and used for miscellaneous purposes such as flushing toilets, laundry, car washing, cleaning walkway buildings, watering, watering animals and plants, etc. It can be used. When using it, install a level gauge in an appropriate location in the trench or water tank, and link the pump switch and three-way water tap. If there is drug-collecting water above a predetermined liquid level in the trench material or water storage tank, the drug-collecting water is pumped up and used, and when the liquid level drops to a predetermined height, the water is measured from the liquid level gauge. By stopping the pump switch in response to a signal and automatically switching the hydrant to the water supply side, the collected water can be used without any problem on the water supply side. Furthermore, the device of the present invention is installed over the entire area or over a wide area around important buildings such as national treasures and buildings where it is difficult to obtain fire prevention water. Paving boards usually contribute to the scenery and traffic of buildings as a beautiful walkway or paving stone-like surface, but in an emergency,
One of the paving slabs can be easily removed by hand through a hole in it, and a fire hose can be inserted to draw water, making it possible to obtain water for fire extinguishing from any part of the surrounding area of the building. The equipment of the present invention can be installed and used in fields and tree cultivation areas. For example, the equipment of the present invention can be used on a farm road. By installing it on agricultural waterways, furrows, working roads in fields, etc., it is possible to effectively use land as a working road that also serves as an agricultural waterway. By connecting an agricultural water supply pipe to the equipment of the present invention via a hydrant, and by providing a liquid level gauge within the equipment of the present invention and linking it with the hydrant, a predetermined amount of water can be stored in the equipment at all times. ．． Therefore, move a hand pump with a watering hose or a pump mounted on a handcart over the paving slabs of this equipment, remove one of the paving slabs near the area where water supply is required, and connect the water intake port of the pump to a ditch or water storage area. By plunging into the tank, water can be taken as needed from any location where this equipment is installed. E. Rainwater, etc., passes through the paving plates and is collected in the water collection grooves, from where it is stored in the water tank. In addition, rainwater, etc. reaches the water tank directly through the paving plates. When the water storage level rises above the specified height, water is drained from the overflow port. Rainwater collected in permeable drainage ditches and water storage tanks buried in farmland etc. gradually permeates into the ground through the walls of the ditch material or through the permeable pipe bodies. As exemplified in Formulation P in Table 1, as a porous ceramic base, a diameter of 2 m
Inorganic raw material coarse particles of m to 7 mm (particle size of 3 mm in formulation example P)
Using a material containing 50% by weight or more of cervene with a diameter of ~5 mm, this is mixed with a small amount of a material that has a heat-sealing effect (Hata feldspar in Formulation Example P), which is then molded into a plate shape and heated to an appropriate temperature. When fired, many penetrating pores are created in the grain boundaries of the coarse grains, resulting in almost uniform water permeability over the entire surface of the plate.Increasing the particle size of the raw material coarse grains improves water permeability, but the product The smoothness of the board surface decreases, and the required thickness of the porous ceramic base increases when laminated with a dense ceramic base. Particle size is 2mm to 7m
m is appropriate. Furthermore, if the coarse particles in the raw material are less than 50% by weight, it is difficult to obtain sufficient water permeability. When two or more types of coarse grains are used, it is possible to obtain a board with a beautiful pattern on the surface that is naturally formed by the coarse grains during molding. By using this porous ceramic base for the surface layer and the dense ceramic base for the lower layer, the overall thickness is reduced to J.
Thinner and lighter than IS concrete slab, JIS
It is possible to obtain a breaking strength that exceeds that of a concrete slab. As for the dense raw material composition, as exemplified in Table 1, Formulation B, inorganic powder with a diameter of 0.1 mm or less (in the case of Formulation B, granulated slag, Mikuni pottery stone, and Motoyama Honbushi clay)
It is necessary to contain 0% by weight or more, and the particle size of the main component is 0%.
．． If it is larger than 1 mm or less than 60% by weight, sufficient breaking strength cannot be obtained. F6 Example Hereinafter, embodiments of the present invention will be explained based on an example shown in the drawings. In Fig. K1, a highly permeable ceramic pavement board M is placed on the top surface of a water collection groove material 31 that is buried underground. A water storage tank (not shown) buried underground is connected to one end of the water collection trench material, and the other end is closed off by a wall. Part 1a. Figure lb shows a first embodiment of the pavement board M, which is composed of a porous ceramic base 1 provided as an upper layer and a dense ceramic base 2 provided as a lower layer, and the A large number of drainage holes H are provided that reach the inside of the porous ceramic base. The method for manufacturing this paving board (first manufacturing method) is as follows. Table 1 The first mixed material corresponding to the substrate 1 and the substrate 2 are prepared according to the formulation shown in Table 1 (column P and column B indicate the raw materials for the porous ceramic substrate 1 and the dense ceramic substrate 2, respectively). Create a second mixed substance corresponding to . That is, in the first step, coarse particles made of an inorganic raw material, fine inorganic heat-fusible particles, and a room-temperature sticky substance are mixed.
Next, in the second step, fine particles made of an inorganic raw material, heat-fusible inorganic fine particles, and a room-temperature sticky substance are mixed. Here, as shown in Table 1, the heat-fusible fine particles include pottery stone,
It corresponds to feldspar and granulated slag, and the room-temperature sticky substance corresponds to clay and water glass. Other coarse particles of inorganic raw materials correspond to Cerben (crushed waste from sanitary ware). These mixed substances are powders, aggregates, or a mixture thereof. Next, in the third step, a template C (Fig. 3) having a large number of protrusions C1 is placed on the lower mold A2 of the press molding die with the protrusions facing upward. In the fourth step, the second mixed substance is filled on the template C in the side mold A3 to a thickness of about 40 mm. In a fifth step, the first mixed material is filled on the second mixed material to a thickness of about 15 mm. In the sixth step, in the upper mold A1 of the press molding machine, the molding pressure is 2
50 kg/cm" and then pressure molded. In the 7th step, the molded product was demolded and the template C was removed to obtain a molded product of 300L x 300B x 30mmT. In the 7a step, this The molded product is heated and dried at 150° C. In the eighth step, the molded product is fired at 1.100° C. for 1 hour. As another manufacturing method (second manufacturing method) for the product of the first example, a template Attach C to the upper mold A1 with its protrusions facing down, and reverse the filling order of the mixed material.Figure 2 shows product No. 2 of paving board M.
An example is shown. In contrast to the first embodiment, the substrates 1.2 are arranged upside down, and a large number of drainage holes H are provided which penetrate at least the dense substrate 2 in the upper layer. The manufacturing method for this is described in the above-mentioned 1.
Or follow the second manufacturing method. This second embodiment has a frequency of 10
00 to 5000 Vpm and vibration press molding at a pressure of 2.5 T without vibration. Section 4a. Figure 4b shows the third embodiment of the paving board M. That is, in addition to the first base 11 made of porous ceramic and the dense ceramic base 2 similar to those in the first embodiment, the dense ceramic base 2 is vertically penetrated at multiple locations to form the first base 11. It consists of a second continuous porous ceramic matrix 12. And, in this manufacturing method (third manufacturing method), instead of the third step,
As a third step, as shown in FIG. 5, a plurality of right cylindrical baffle members D1 are placed on the penetrating piece A4 of the lower die A2 with its axis vertical, leaving gaps from the side wall of the side die A3. (5 pieces shown) are arranged at equal intervals from each other. As a fourth step, the second mixture is filled between the mold side mold A3 and the columnar body D1 up to the height of this columnar body (40 mm). As a fifth step, the column D1 is extracted downward via the lifting support member E and the piston cylinder machine ellipse F until its upper surface is flush with the upper surface of the lower mold A2. As a sixth step, the first mixed substance is applied 55 m from the bottom of the mold, covering the second mixture and into the space where the baffle member was.
Fill to a height of m. In the seventh step, the product is press-formed at a pressure of 2501 g/cm. As another manufacturing method (fourth manufacturing method) for the product of the third example, a plate having through-holes corresponding to the direct-obstruction member is used. Using a body baffle member, reverse the filling order of the mixed substance.Next, a fourth example of the product of the paving board M is shown in Fig. 6.That is,
It consists of a flat porous ceramic base 1 and a dense ceramic base 2 provided on its peripheral side. How to make this《
The fifth manufacturing method is as follows. As shown in FIG. 7, in the third step, a simple baffle member D2 with a rectangular cross section that is in contact with the entire side wall of the side mold is formed into an elevating member that penetrates the lower mold A2 with its axis vertical. Place it on E. In the fourth step, the first mixed substance is filled into the cylindrical body D2 up to its upper end. In the fifth step, the straight cylindrical body D2 is pulled out downward by the piston cylinder mechanism F until its upper surface is flush with the upper surface of the lower mold A2. In the sixth step, the space where the straight cylindrical body D2 was located is filled with the second mixed substance. In the seventh step, the upper die is pressed and pressure molded. At this time, the lower die A2 and the baffle member D2 are supported by the lower die pedestal G to withstand the load.

As another manufacturing method (sixth manufacturing method) of the fourth example of the product, a straight cylindrical body obstruction member placed with a gap corresponding to the straight cylindrical body obstruction member left between the side mold A3 and the side mold A3 is used, and mixing is performed. Reverse the filling order of substances. Next, Fig. 8 shows a fifth example of the paving board M product. That is, in addition to what is shown in FIG. 6, in addition to the peripheral first element 21, a second dense ceramic base 2 is provided that vertically penetrates the porous ceramic base 1.
1 is provided. This manufacturing method (seventh manufacturing method) includes the seventh manufacturing method in the third step.
9.10 instead of the straight cylindrical baffle member D2 shown in the figure.
As shown in the figure, a plate baffle member D3 having a plurality of mold holes (four in the figure) uniformly distributed is arranged. The rest is the same as the fifth manufacturing method above. As another manufacturing method (eighth manufacturing method) of the fifth example of the product, four straight cylindrical bodies corresponding to the mold hole and the thick wall portion of the baffle member D3 are placed in contact with each other, and the order of filling the mixed substance is reversed. ．． Here, the test results of Product Examples 1 to 5 of Paving Board M are shown in Table 2. As shown in Figures 1a and 1b, for example, if 18 holes are made in a 30cm x 30cm square pavement board through the underlying dense ceramic base, the result will be as shown in Table 2. With a thickness of 30 mm, it has a breaking strength of 1.313 kgf, which exceeds that of a 60 mm thick JIS concrete slab. The amount of water permeation in Example 1 corresponds to a rainfall of 270 mm/hour, which sufficiently exceeds the maximum rainfall in urban areas in Japan. When manufactured using vibration molding, the strength is slightly lower than when press molding is used, but since there is less clogging of the porous ceramic substrate than when press molding is used, it is possible to manufacture a good paving board with good water permeability. ．． In order to maintain uniform water permeability on the surface of the pavement board, the appropriate thickness of the surface layer is about 5 mm to 10 mm. By mixing pigments into only the surface layer material in a thin surface layer, it is possible to effectively use pigments, which are much more expensive than the main raw material, even in small amounts. Even when used for long periods of time, there is almost no fading due to wear.

When a dense ceramic base is used for the surface layer, various patterns can be drawn on the paving board by changing the shape, number, and arrangement of circular, elliptical, etc. through holes.

(In this case, the drainage hole may penetrate to the lower layer.) In this case, the width of the hole (minor axis) should preferably be 5 mm or less to prevent accidents such as high heels, umbrellas, etc. Even when a beautiful glaze is applied, the number and arrangement of holes has the effect of preventing pedestrians and cars from slipping.Furthermore, by using a dense ceramic material for the lower layer around the periphery of the paving board, the interior of the lower layer is more stable. A coarse-grained, inexpensive material can be used as the main raw material.As shown in Product Examples 4 and 5, a dense ceramic base is used for the periphery and a porous ceramic base is used for part or most of the inside. When used, it is possible to manufacture a water-permeable pavement board that is thin, lightweight, has sufficient breaking strength, and has good workability, depending on the ratio and arrangement of the dense ceramic base.According to these examples, porous Since the porous ceramic matrix occupies a considerable portion of the surface layer, it is necessary to use a porous ceramic matrix material that has excellent wear resistance and considerable strength, as in the case of Example 1. Compared to this, the amount of porous ceramic base material used is larger. Therefore, the cost of porous ceramic material is lower than that of Example 1 or Example 2.
It will be more expensive than in the case of However, since the porous ceramic material penetrates from the surface to the back of the paving board,
As shown in Table 2, a pavement board with far better water permeability than those of Examples 1 and 2 can be obtained. In addition, by creating various straight lines and curves as the boundary between the dense ceramic base and the porous ceramic base, it is possible to draw letters, figures, etc. on the surface of the paving board. The cross-sectional shape of the drainage hole can be selected from various shapes such as circular, oval, and rectangular, but the width (diameter) of the hole must be 2 mm or more in order to resist the surface tension of water and obtain sufficient water permeability. In addition, in order for the dense ceramic base to have sufficient fracture resistance as a paving board, it is desirable that the thickness be 30 mm or less.

As shown in Figure 6.8, when arranging dense ceramic substrates and porous ceramic substrates in multiple layers (multilayers) in the horizontal direction (vertical and horizontal directions of the paving board), inexpensive materials are used and the molded product is It is desirable to place a dense ceramic base around the periphery of the molded product to prevent damage to the periphery of the paving board during handling such as removal from the mold, firing, transportation, and paving. In any of the above cases, the inorganic raw materials that are the main components of porous and dense ceramic base materials include natural raw materials such as silica, feldspar, pottery stone, clay, and shirasu, or tiles, sanitary ware, ceramic pipes, etc. Shredded ceramic products such as shelves and glass, defective ceramic products, used scraps, etc., synthetic raw materials such as alumina, mullite, cordierite, etc. that are normally used as raw materials for ceramics, and slag. Wastes such as , fly ash, red mud, garbage incineration ash, sewage/human waste sludge incineration ash, and rice husk incineration ash are used. The firing temperature of the molded product needs to be selected at a temperature that does not cause the main component to lose its shape due to softening, and at the same time, a temperature that appropriately softens and melts the heat-sealing component in the raw material and causes the main component to stick. Although it varies depending on the type and composition of the raw materials used, a temperature of 800°C is required to obtain sufficient fracture resistance as a paving board.
A higher firing temperature is required. Next, in Fig. K2, a highly permeable ceramic pavement board M is placed on the top surface of a water tank 3 that is buried underground and has an overflow port 33a on its side wall. A drain pipe 34 is connected to the overflow port 33a. Here, near the lower surface of the highly permeable ceramic pavement board M,
Alternatively, a far-infrared ceramic layer made of alumina, cordierite, or the like that emits far-infrared rays at a temperature of 0 to 50°C is arranged near the inner surface of the water collecting groove material 31 or the water storage tank 33.
This far-infrared ceramic layer may be placed on the inner surface of the groove material or water tank itself, or may be coated with oil-based, water-based, synthetic resin, or other paint mixed with powdered ceramic, or polyethylene, polypropylene, ABS, etc., on the inner surface. It is coated with a resin-like substance. Alternatively, it is constructed by adhering a far-infrared ceramic plate to the inner surface, and is buried in a planted area such as farmland, as shown in Figure K1 above, and has a water permeability of 10 cm/sec in part or in whole. A highly permeable ceramic paving board M is placed on the upper surface of a water collection groove material made of a porous ceramic body with a porous ceramic body of ~10-'cm/sec. A highly permeable ceramic pavement board M is placed on the upper surface of the water collection groove material 31. The base end of the tube body 33 is connected to the lower side wall of the water collection groove body.The tip of the tube body 33 is closed. , water permeability 1
It is made of porous ceramic with a permeability of 0-"cm/sec to 10'cm/sec. Here, the porous ceramic tube having the above-mentioned water permeability is manufactured as follows.Wollastonite 5 is used as a raw material.
0%, Honbushi clay 35%, and talc 15% granules are mixed. Since wollastonite has a flat plate or needle shape with a high aspect ratio, the product is porous and has high bending strength.Water is added to the raw material with the above composition by 15 to 20%,
Extrusion molded using a vacuum forming machine, cut into appropriate lengths (1 to 2 m), and dried (natural drying for 1 to 3 days or far infrared drying for 2 to 3 days)
After 4 hours), the product was baked at 1150°C.By changing the water addition rate and extrusion pressure during molding, the porosity of the product can be changed, making it possible to create products with different water permeability. ．． By this method, 101~10-'cm
/second water permeability can be made, 10-2
A water permeability of ~10-'cm/sec can be achieved by drilling a large number of holes with a diameter of 0.2-1 mm in the above product. Note that if the water permeability is less than 10-'cm/sec, the underground humidity is too low, and if it is greater than 10-2, the underground humidity is too high, both of which are inappropriate as a planting environment. Although this tube body is made of ceramic, it is machinable (easily machined) and can be processed by drilling, cutting, threading, etc. using commercially available carbide tools. In addition, a water storage tank with water permeability is also manufactured in the manner described above. Figures K4 and K5 show an embodiment of a portion where water collected from the roof, highway, etc. is guided to the water collecting groove material 31 and the water storage tank 33 through the stand R. That is, in Fig. K4, there is a filter box 41 that is provided facing the lower end of the bucket R and filters out foreign substances such as rainwater, and a filter box 41 that is housed inside to temporarily retain rainwater and the like. A relay box 42 and a relay pipe 43 connected to the side wall of the relay box and introduced into the water collecting groove material or the water storage tank are provided. The filtration box 41 consists of an upper mesh cylinder and a lower part for collecting foreign matter. In Fig. K5, a filter body 44 consisting of a wide conical net at the bottom is provided inside the lower part of the stand R to filter out foreign substances such as rainwater, and a filter body 44 is fixed to the upper end to receive rainwater etc. Upper wide conical cylinder 45
and a relay pipe 46 connected to the lower end of the conical cylinder, bent and penetrating the wall of the stand, and introduced into the water collecting groove material or the water storage tank. In addition, 47 is the filter body 4

In addition, even if the surface is covered with a beautiful glaze, the number and arrangement of holes can prevent pedestrians and cars from slipping. With the ninth configuration, in addition to the effects of the seventh configuration, a cheaper product can be obtained by using a coarse-grained, inexpensive material for the lower layer. The 10th configuration provides extremely good water permeability in addition to the effects of the 7th configuration. In addition to the effects of the 10th configuration, the 11th horizontal formation allows characters, figures, etc. to be drawn on the board surface by making the boundaries of each substrate into various straight lines and curves.

With the 12th and 13th configurations, in addition to the effects of any one of the 1st to 1l elliptical configurations, a large amount of water collected from roofs and highways can be efficiently collected without foreign matter.
