Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a legal framework used mainly in cold regions and a vegetation construction method using the same.

(Prior art) Traditionally, slope frames are made of concrete or iron frames that are pre-fabricated at a factory and are shaped into square, rectangular, or diamond-shaped lattice shapes, or hexagonal or circular shapes on the construction slope surface. formed by joining together.

In this type of vegetation construction method using a legal framework, it is common to add soil within the framework and then cover the surface of the soil with vegetation, such as with grass.

In addition, for steep rock slopes, etc., we construct formwork so that it is in close contact with the construction slope, arrange reinforcing bars within this formwork, then pour concrete and cast the frame on-site. form a frame. Usually, vegetation sandbags are placed within such legal frameworks to promote vegetation.

(Problems to be Solved by the Invention) However, in the above-mentioned slope made of factory-produced frames and the construction method using the same, since the frame is a continuous rigid body, the slope This makes it difficult to install in close contact with the slope because it does not adhere to the slope or uneven surface.

As a result, a gap is created between the slope surface and the bottom surface of the slope frame, and even a small amount of water on the slope surface causes the soil inside the frame to wash out, and this phenomenon occurs because the surface is covered with turf. They cannot be easily detected, leading to collapse during heavy rains. In addition, in areas such as cold regions where frost heave and frost pillars occur and are subject to repeated freezing and thawing, the slope foundation is repeatedly lifted up by frost heave and frost pillars and restored by freezing and thawing. Because the body lacks restoring force, once lifted, it maintains that state, creating a larger space between the frame and the slope than described above.

Although the legal framework made of cast-in-place concrete and the construction method using the same do not cause the above-mentioned problems, the construction takes time and effort, and construction costs are high. In addition, the vegetation sandbags placed and fixed within the frame are stacked along the slope, so the lower the vegetation sandbags are, the more the weight they receive is doubled.
Within a short period of time, the pieces settle while being consolidated in the direction of the foot of the slope, creating gaps and spaces at the top of the frame, while the lower part of the frame becomes overlapping and may fall out of the frame.

In view of the problems faced by the prior art, the present invention
It can be constructed in close contact with the slope, and it follows the slope and does not create any gaps between it and the slope, even during frost heaving, frost pillars, and restoration. The purpose of this invention is to provide a method of constructing a legal framework and vegetation that can reduce construction costs.

In addition to the above-mentioned objects, it is another object of the present invention to provide a vegetation construction method that can provide reliable, highly permanent, and stable vegetation in cold regions.

(Means for Solving the Problems 1-) In order to achieve the above-mentioned object, the legal frame of the present invention is constructed by connecting five or more block members in series at required intervals by flexible connecting members. form a frame of
The feature is that this frame is arranged and fixed on a slope in an arbitrary frame shape.

The frame has cross-blocking members that cross-engage each other at intersections of the frame.

In the above-mentioned vegetation construction method using a slope frame, a soil storage bag filled with soil is placed in the frame so that the top surface is almost flat, and the peripheral edge of this soil storage bag is placed on the top surface of the block member. Either fix the vegetation bag filled with vegetation base material to the top surface of the soil storage bag, or lay a base sheet within the frame so as to cover the inner surface of the frame and the slope, and After the peripheral portion is fixed to the upper surface of the block member, soil is piled up on the base sheet while being compacted, and the upper surface of the soil is made substantially flat and grass or the like is directly planted thereon. Further, the soil is further covered with a net, and the seeds are sprayed onto this net.

The vegetation bag has a covering layer made of a material that does not impede germination and growth, and which has a larger surface area than the base layer, on the top surface of a base layer made of a material woven into a mesh pattern, and on this covering layer. By sewing a predetermined position to the base layer while providing slack, a vegetation base material storage space is formed that communicates vertically and horizontally between the covering layer and the base layer and bulges out when the interior is filled with the vegetation base material. Preferably, the periphery of the integrated base layer and coating layer where they overlap is fixed with a belt or the like, and an injection port is provided at a desired position for filling the space with the vegetation base material.

(Function) When this frame is placed on a slope and fixed by driving anchor bolts into predetermined positions, each block member will
Since it can be bent vertically and horizontally by the connecting member, it adheres closely to the unevenness of the slope and maintains its adhesion even when the slope base moves vertically due to frost heaving or frost pillars. .

In addition, a top soil base material is disposed within the frame, and the storage bag or the peripheral edge of the base layer sheet that receives this top layer sheet is fixed to the top surface of the block member, so that the weight of the top layer blocks the base material. This is to press the member against the slope and maintain the above-mentioned close contact state even more firmly.

The frame body may be placed at a position corresponding to the shape and size of the storage bag, vegetation bag, etc. placed within the frame by utilizing its flexibility. The shape of the frame can be changed and reinforced easily.

In addition, in the vegetation construction method according to the present invention, soil is filled into a storage bag or wrapped in a base sheet and placed and fixed within a frame, making it possible to grow vegetation even on soilless slopes and bare land. do.

In addition, even if the above-mentioned top soil becomes excessively water-containing during spring water generation or heavy rain, the storage bag or base layer sheet gently dehydrates the soil, and not only does the top soil not flow out, but also Ensuring vegetation on the top surface of the soil with sufficient water retention.

The vegetation bag fixed to the top surface of the soil is formed so that the space filled with the vegetation base material, which communicates vertically and horizontally inside the top surface, bulges out in the shape of an enemy or lump, but the bottom surface is almost flat.
It is fixed in close contact with the soil to effectively grow vegetation.

(Examples) Hereinafter, the present invention will be described in detail based on illustrated examples.

FIG. 1 shows a legal frame according to an embodiment of the present invention.

This legal frame is formed by intersecting a normal length direction frame 1 and a normal width direction frame 2 at a predetermined interval in the shape of a rectangular lattice frame. Both frame bodies 1.2 are a chain consisting of a large number of rectangular parallelepiped block members 3.3' and a belt member 4.4' that connects the block members 3.3' in series at a required interval. It has a 3n shape.

The block members 3, 3' are made of a rectangular parallelepiped material that has a certain degree of rigidity and is lightweight, for example, made of deciduous pine wood, which is sufficiently dried, soaked in preservative straw material CCA and dried, or made of a resin material. is formed. The block members 3, 3' adhere closely to the undulations and irregularities of the slope, have the length necessary to maintain the shape of the slope, and provide stability in the width direction of the frame, as well as vegetation bags, storage bags, etc., which will be described later. The height is selected in consideration of the width required to secure the storage sheet and the thickness of the soil layer to be piled up within the frame. The thickness of the soil layer is determined based on the soil quality of the slope base, water veins, direction of the slope, sunlight hours, etc. By the way, in this example, the block member 3.3° has a length of 150+++a+ and a width of 50II1m.
It forms a rectangular parallelepiped shape with a height of 80 mm+. Further, it is preferable that the block members 3 and 3° have projections and depressions formed on their bottom surfaces to prevent slipping.

In addition, the reference numeral 5 in the figure is a through hole that passes through the block members 3, 3' in the vertical direction, into which an auxiliary anchor bolt is driven. A normal anchor bolt with an L-shaped head is used as the auxiliary anchor bolt.

The belt member 4.4' is formed of a weather-resistant and durable synthetic fiber material, for example, into a long belt shape with a width of about half the height of the block member 3. , 3゛ are fixed on both sides with appropriate clasps. The interval connecting block members 3 and 3° is
Even if the belt member 4.4° is slightly loosened, the block member 3.3
゜ is the length that does not collide. In this embodiment, the above-mentioned block members 3.3 degrees are connected with an interval of 1100 Ua.

A portion of this belt member 4.4° extends outwardly to form a loop and is stopped by the main anchor bolt 6. For the main anchor port 6, it is preferable to use an anchor bolt whose head has a T-shape or a hairpin shape, for example, to prevent it from coming off.

The block members 3A and 3°B at the intersection of the legal width direction frame 1 and the legal width direction frame 2 are formed in shapes that engage with each other. As shown in FIG. 2, the cross block 3A of the memorial service frame 1 has a portion of its lower surface 3a cut out at one end.
In addition, as shown in FIG. 3, the cross block 3'B of the legal direction frame 2 has a central upper surface 3°b that is large enough to receive the above-mentioned one end of the cross block of the legal direction frame 1. It is cut away by a small amount. And both intersection blocks 3A,
At 3°B, the top surfaces are flush when stacked as shown in FIG. In order to adopt such an engagement structure, the belt member 4 of the legal width direction frame 1 is fixed to the upper half of the side surface of the block member 3, and the belt member 4 of the legal width direction frame 2
' is fixed to the lower half of the side surface of the block member 3' to prevent the two belt members 4, 4' from intersecting at the intersection.

Both frames 1.2 are assembled in a lattice shape at required intervals, and are fixed on the construction slope using anchor bolts to form a slope. In this slope frame, the block members of the frame body are connected by a belt member, so that the frame body can be flexibly bent vertically and horizontally, and is fixed in close contact with the unevenness of the slope surface (see Fig. 5).

Next, an example of the construction of vegetation within a legal framework will be described with reference to FIG. 6. This figure mainly shows the case where it is applied to a long slope of a memorial service.

In this example, the storage bag 7 is arranged and fixed within the frame. The storage bag 7 is formed into a bag slightly larger than the vegetation area within the legal framework by sewing synthetic fibers woven into a mesh shape through which grassroot threads can easily pass. The lower surface 8 of the storage bag, which comes into close contact with the slope, has slack (see Figure 7), and the upper surface 9, which does not have any slack, and the lower surface 8 are divided into a plurality of chambers with internal spaces that can communicate with each other at predetermined positions. It is sutured in a linear manner. This partitioned chamber prevents the soil base material 10 inside from being biased toward the foot of the slope.

Further, at an appropriate position on the upper surface 9 of the storage bag 7, an injection port (not shown) is provided for filling the inside with the soil base material 1O.

Before the storage bag 7 is filled with soil, the peripheral edge thereof is fixed to the frame 1.2 with a clasp or the like, and the soil base material 10 is poured through pouring [1]. At this time, the upper surface 9 of the storage bag 7 should preferably be flat, and the lower surface 8 should be brought into close contact with the slope. If one aspect of the memorial service frame is large, the belt 11 may be passed between the frames 1 in the direction of the memorial service.

Furthermore, instead of pouring the soil base material 10 into the storage bag 7 at the site, the soil base material 10 may be poured in advance at a factory and carried onto the construction slope. In this case, as shown in FIG. 8, the storage bag 7° is formed to a size suitable for transportation.

Each storage bag 7° is fixed to the frame in the same manner as in the above example.

The soil base material 10 filled in the storage bags 7 and 7' is made of soil produced at the construction site mixed with permanent organic fertilizer.

The vegetation bag 12 is fixed to the flat upper surface of the storage bag 7.7° configured as described above. This vegetation bag 12 is
It may be similar to the conventional one in which synthetic fibers are woven into a mesh shape and sewn into a bag shape, but if the one shown in Figs. It can be fixed tightly to the above-mentioned flat upper surface without receiving it.

To specifically explain the vegetation bag 12, first, the vegetation bag 1
2 has a surface layer 13 on top, a base layer 14 on the bottom, and a covering layer 15 between the surface layer 13 and the base layer 14, and the peripheral edges of these are sewn together with belts 16 and 17 to form a rectangular bag. It is formed in the shape of

The surface layer 13 is made of a lightweight, water-permeable sheet, for example, a sheet woven with coarse chemical iam. This surface layer 13 protects the vegetation base material 18 filled in the bag from cold air, frost,
This is to shield from wind and direct sunlight, and to prevent the surface vegetation base material 18 from being washed away by the impact force of raindrops during rain, promoting seed germination and growth, protecting young grass, When the plant reaches a certain height, it is peeled off from the vegetation cover.
It is a temporary protective sheet.

The base layer 14 is made of cloth woven with chemical fibers, and has strong durability, elasticity at low temperatures, and minute gaps.
It forms the base of this vegetation bag 12. Grass root threads develop and extend their roots deep through the interstices of this substratum 14, forming a vegetation bag 12.
is closely and stably attached to the soil base material 10 in the storage bag 7.

The covering layer 15 has a three-layer structure, and the first covering layer 15a, which is in contact with the surface layer 13, has a gap for the grass stems to pass through, is rich in heat retention, and is good for the growth of grass stems. It is composed of a sheet body that deteriorates and collapses over time, such as a cloth woven from natural plant fibers or a nonwoven fabric made of continuous filaments made of chemical fibers. The second coating layer 15b is the third coating layer 15
This layer, together with c, permanently holds and supports the vegetation base material, lush stems and leaves, and grown roots, and prevents them from flowing out.This layer is made of a highly durable net material. Third coating layer 1
The layer 5c is the lowest layer of the covering layer 15 and is in contact with the base layer 14, and is made of a cloth woven from chemical fibers, which is durable and has a small space through which grass stems can pass. Therefore, since the intermediate second covering layer 15b has voids, the covering layer 15 forms a thin layer of gas in this part, and plays the role of a heat insulating layer that gently transmits solar radiation and blocks cold air. .

And these first to third coating layers 15a to 15c
, the surface area is larger than the surface area of base layer 4,
When placed on the base layer 14 with its periphery aligned with the base layer 14, it is formed in a size that has a considerable amount of room. A space 19 is formed between the covering layer 15 and the base layer 14 to accommodate the vegetation base material 18 . This space 19 communicates with the surface of the base layer 14 in the form of vertical and horizontal base lines. The horizontal space f9a and the vertical space 19b bulge out when filled with the vegetation base material 18 because the covering layer 15 is sutured with slack to the base layer 14, respectively. do.

Further, these spaces 19 are generally formed to be wider than either the horizontal space 19a or the vertical space 19b.

Further, in the lateral space adjacent to the joint 20 shown in Figure 9, a heat-insulating and water-retaining sheet 21 is installed along the inner surface of the seamed end of the covering layer, as shown in Figure 7tX12. The heat-retaining and water-retaining sheet 21 is made of a nonwoven mat made of corrosion-resistant and flexible chemical fibers.

In addition, 22 is the soil population of the vegetation base material 18 provided on the upper part of the vegetation bag 12.

The vegetation bag 12 constructed in this way is placed on the upper surface of the storage bag 7, and fixed by twisting the left and right suspension belts 23 by 90 degrees in the width direction and driving the main anchor through the loops. At locations where the hanging belt 23 is not provided, a main anchor or an auxiliary anchor is driven into a predetermined position of the vertical belt 16 or the horizontal belt 17. By using the hanging heald 23, the weight of the vegetation bag 12 is reliably transmitted to the anchor, unlike the case where the belt 16, 17 is simply drilled and passed through, resulting in excellent durability.

The vegetation base material 18 is poured into the fixed vegetation bag 12 from the injection port 22.
When filled, the vegetation base material 18 flows down through the vertical space 19b, stays there, and fills the lowermost horizontal space 19.
It gradually fills the upper lateral space 19a from point a, forming an enemy-like bulge. At this time, since the path flowing into the space 19 moves from the vertical direction to the horizontal direction, the density of the vegetation base material 18 in the vertical space increases. Further, as described above, since the joint portion 20 between the covering layer 15 and the base layer 14 has a horizontally long rectangular shape, the vertical space portion 1
9b, a portion surrounded by the ends of the four joint portions 20 bulges out from other portions of the vertical space 19b and the horizontal space 19a, and a hemispherical bulge is formed in this portion (10th (see figure). As a result, the vegetation density of the vegetation bag 12 increases by several tens of percent or more in the longitudinal direction, and deformation after dehydration is reduced. In addition, in the lateral direction, since it is perpendicular to the slope, the flow velocity when surface water flows down is suppressed, and the residence time of water is increased.
0 will be supplied with water.

Evaporation of this water is suppressed at the joint portion 20, which is located between the bulging vertical and horizontal spaces 19.

In this way, in the above-mentioned vegetation bag 12, the covering layer 15 is sewn to the base layer 14 with slack, and the vegetation base material 18 is filled in the vertically and horizontally connected spaces 19 formed by this slack. The back surface of the soil base material 1 does not swell.
0 (see Figure 15). By fixing such a vegetation bag 12 on the top surface of the storage bag 7, the storage bag 7 can prevent depletion and provide a permanent plant when the slope base is bedrock or hard soil with poor water veins, sunshine hours are long, and there is no rainfall. vegetation is achieved.

FIG. 16 shows another example of a vegetation bag, in which the upper surface is made to have more room in the length direction (in the direction in the figure) than the lower surface, and the peripheral edges are aligned leaving one side that will be the injection opening 23. It sticks to the surface.

Further, the upper surface and the lower surface are sewn together in the width direction at appropriate intervals in the length direction, and a plurality of independent bag bodies 24 are formed in parallel. These main bodies are provided with an intermediate suture line 26 in the center that is approximately parallel to the dividing suture line 25 and does not extend to both ends.

Then, in use, the above-mentioned opening 23 is filled with dry vegetation base material that is not mixed with water until the upper surface is sufficiently swollen, and the opening 2 is closed by an appropriate means. As shown in FIG. 17, this vegetation bag 27 has a shape in which each bag body 24 is swollen into a flat donut shape, and the bag bodies are independent from each other. Since it is divided in the length direction of the bag, even if it is fixed to the upper surface of the storage bag 7, the vegetation base material inside will not be omnipresent in the direction of the foot of the slope.

In addition, since the vegetation base material filled inside is dry, the overall weight is reduced, making it easier to transport. The vegetation bag 27 fixed on the storage bag 7 germinates when it rains, but a surface layer may be provided to prevent it from heating and protect the young grass. The vegetation bag according to the embodiment shown in FIG. 9 may also be filled with dried vegetation base material.

Fig. 18 shows another example of the above-mentioned method of constructing a 7148 slope, which is mainly used on slopes with gentle slopes. In this construction method, a base layer sheet 28 made of durable synthetic fibers is laid on the inner surface and slope of the frame 1.2, and on top of that, soil 29 is piled up while being compacted, and the top surface is made flat. Finish. The base sheet 28 prevents the soil 29 from flowing out. In order to prevent the base layer sheet 2 from moving the soil 29 toward the foot of the slope, it is preferable to add a frame 2 in the slope direction. Vegetation such as turf grass is grown directly on the surface of the soil, but the 19th
As shown in the figure, if a net 30 made of durable synthetic fibers is stretched and vegetation is sprayed onto the net 30, it can be applied to steep slopes.

Further, in such a vegetation work, the vegetation bag described above may be fixed on the top surface of the soil or on the net.

Next, construction examples 1 to 1 using the slope frame and its construction method according to the present invention will be explained.

[Construction Results] (Regarding germination, the date on which sprouts appeared on the coating surface layer was used as a reference) As is clear from the above results, good results were obtained in all construction examples. In construction example 4, subsidence of soil was observed within the frame, but it was not significant enough to affect vegetation.

Note that the block member used in the present invention is not limited to the rectangular parallelepiped shape shown in the above embodiment, but may have any other shape that forms a legal frame. Further, as the member for connecting the block members, even if it is other than the belt member shown in the above embodiment, as long as it connects the block members flexibly in the vertical and horizontal directions,
It does not matter what material it is made of, such as wire or strip material.

(Effects of the Invention) As described above, according to the legal frame according to the present invention, the frame forming the legal frame forms a chain in which a plurality of block members are connected by flexible connecting members, and the block members are interconnected. Since it can be bent horizontally and vertically, the frame itself can follow the vertical movement of the slope base due to frost heaving, frost pillars, etc. and maintain its adhesion.

In addition, because the slope is bendable as mentioned above, it can be laid as is without smoothing the existing slope if it is slightly uneven, and the frame shape can be easily changed on the slope. ,
For example, it can be laid so as to match the shape and size of a storage bag or a vegetation bag to be fixed within the frame.

Furthermore, the frame body is economical in its constituent members, and can be easily fixed to a slope by using anchor bolts, so construction is easy and the construction costs are not high.

In addition, in the vegetation construction method according to the present invention, the above-mentioned slope frame is used, and the soil in the frame is covered with a soil storage bag or a base layer sheet from the contact surface with the frame.
The soil will not flow out from the bottom of the frame, and even if the soil becomes overly hydrated due to spring water on the slope, filtration and dewatering will be carried out gently by the storage bag or base sheet.
Similarly, it is possible to effectively prevent soil from flowing out.

The soil base material constructed in this way permanently provides a stable environment for plant growth, allowing effective vegetation growth, especially on soilless slopes and bare areas where it is difficult to grow vegetation. It is what makes vegetation possible.

Furthermore, as a vegetation bag used in the construction method of the present invention, a covering layer is sewn to the -L side of the five base layers with slack, thereby creating vertical and horizontal communication between the covering layer and the base layer, and filling the inside with vegetation base material. nlL, \, which forms a vegetation base material accommodation space that bulges out in an enemy-like manner when
Even when filled with vegetation base material, the back of the vegetation bag, which is the back side of the layer, does not bulge and can be fixed tightly to the construction surface.
Since the roots are also firmly fixed in the ground, the risk of collapse can be eliminated, and vegetation can be planted effectively by being closely connected to the soil.
