The storage body (10) is obtained, for example, as follows. That is, a plurality of vertical strips extending in parallel at a predetermined interval and a plurality of horizontal strips extending in parallel at a predetermined interval are entwined and woven, and then sprayed, rolled, or dipped. The surface finishing treatment is performed with a synthetic resin such as an acrylic resin by the method described above, and the crossing point between the vertical strip and the horizontal strip is fixed by the adhesive force of the synthetic resin. Naturally, the portions other than the intersection points in the vertical strips and the horizontal strips are covered with the synthetic resin, whereby the vertical strips and the horizontal strips are reinforced, and they have a strong elasticity (shape retention). An excellent) storage body (10) can be obtained. By the way, the storage body (10)
The tensile strength is preferably 2 to 15 tf / m, and the flexural modulus (tensile modulus) is 1.0 × 10 ² k.
It is preferably gf / cm ² or more.

The above-mentioned longitudinal / horizontal strips are made of synthetic fibers such as polyester fibers, polyolefin fibers and nylon fibers, and their thickness is, for example, 300 to 3,000 denier.

The size of the mesh of the storage body (10) is 2 to
It is 55 mm. If the size of the mesh is less than 2 mm, water permeability may be impaired when the finally obtained mesh-like container is used as a water permeable member for civil engineering, and if it exceeds 55 mm, a filling material such as crushed stone is used. Is more likely to get out of the mesh.

On the back surface side of the one lid portion (16) of the storage body (10), five male surface fasteners (18) extending in the longitudinal direction of the storage body (10) are arranged at a predetermined interval. It is set up. On the surface side of the other lid (16),
At its free end, the hook-and-loop fastener male part (1
One surface fastener female part (20) is provided in a direction orthogonal to 8).

Further, connecting belts (22) are attached to the storage body (10) by sewing at the free ends of the side surfaces (14) (four places in total). Each connection belt (22) has a plurality of connection holes (24) arranged side by side in the longitudinal direction of the storage body by weaving or heat processing. The connecting belt (22) is made of, for example, polyester woven cloth and has a weaving width of 100 to 200 m.

The net-like storage body (A) of the present invention is formed by using two storage main bodies (10) having the above-mentioned structure. That is, the two storage main bodies (10) are placed in contact with the bottom lower surface of one storage main body (10) and the bottom upper surface of the other storage main body (10), and the respective bottom portions (12) (12) are Align them and make them orthogonal to each other (see the chain double-dashed line in FIG. 1) (in both cases, the surface on which the hanging belt (26) is present is the lower side).

In this state, as shown in FIG.
Parts other than 2), that is, side part (14) and lid part (16)
Is lifted upward with the boundary between the bottom portion (12) and the side surface portion (14) as a folding curve. Then, the two connecting belts (22) adjacent to each other by lifting the side surface part (14) are connected to the connecting holes (24) of the ropes (30) (wire diameters 4 to 4) as shown in FIG.
8 mmφ and strength of 400 to 800 kgf / piece) to connect the side surface portions (14) adjacent to each other.

By fixing the ropes (30) at all four corners, the two storage main bodies (10) can be molded into an upper open type rectangular parallelepiped shape (the upper open portion is for filling). It becomes an opening (32)). For each corner, use one rope (four as a whole) like a shoelace for connecting belt (2
2) may be connected, or one rope may be used for a pair of adjacent holes at one corner. Further, instead of the rope (30), a belt, a tape, a metal fitting, a plastic fixing jig, a metal ring, a coil (inner diameter 10 to 30 mmφ, length 50 to 150).
0 mm) can also be used.

In the above embodiment, the net-like storage body (A) is composed of two storage main bodies (10), but the present invention is not limited to this. As shown in FIG. 4, the storage body (10) may be formed in a cross shape from the beginning.

In any case, the net-shaped container (A) formed in a rectangular parallelepiped shape is housed in a hollow rectangular parallelepiped frame receiver (B) opened upward as shown in FIG. In this state, for example, crushed stones (not shown) are filled inside the net-like storage body (A), but at this time, the lid portion (16) and the hanging belt (26) are frame receiving bodies (B). After filling the inside of the reticulated container (A) with crushed stones almost completely, the filling opening (32) is closed by the lid (16).
At this time, first, the lid portion (1
6) is closed, and then, the lid portion (16) at the position opposite to the lid portion (16) (this lid portion (16) is a female fastener (2).
2) having two opposing parts can be firmly fixed (Fig. 6).
reference). This operation is performed by another pair of the lids (16) facing each other.
Repeat (16).

The closing of the filling opening (32) was performed by the surface fasteners arranged orthogonal to each other. By doing so, the height of the storage main body can be changed by changing the volume of the filling. It can cope with the fluctuation of.

In this way, the upper filling opening (32)
After closing the, close the net-like storage (A) to the belt (2
6), remove from the frame receiver (B), lay it down at the appropriate place (see Fig. 7),
Furthermore, it loads on it. In other words, for example, a riverbank protection and greening construction site (see FIG. 8), a sheet pile revetment protection construction site (see FIG. 9), a harbor revetment protection construction site (see FIG. 1).
No. 0), pier protection construction site (see FIG. 11), or landfill construction site, etc., and load them appropriately. In this case, since the net-like container (A) of the present invention is excellent in water permeability, it is preferable to lay it on site taking this point into consideration. It is also possible to fill a large amount of activated carbon in the interior and use it for water regeneration in a sewage treatment plant, a water treatment plant, or the like.

The water permeability can be improved by filling the inside of the net-like container (A) with a member having water permeability itself, instead of filling the crushed stone.

The net-like container (A) of the present invention is not only excellent in water permeability but also excellent in shape retention, and unlike the conventional net-like container, the shape after installation is when crushed stones are enclosed inside. However, since it is constant, that is, after installation, any of them has a rectangular parallelepiped shape, the work efficiency of laying and laying can be dramatically improved, and a series of laying and laying work can be performed uniformly.

Further, as described above, since the net-like storage body of the present invention has a constant shape after installation, it is possible to grasp in advance approximately exactly how many net-like storage bodies (A) are necessary in one construction. Therefore, it is possible to minimize the cost for preparing the extra net-like container (A).

Further, the net-like container (A) is installed in an unstable place, so that even if the packed crushed stones or earth and sand cause internal flow, the net-like container (A) of the present invention is as described above. Since the shape retention is excellent, there is no concern that the shape will be greatly collapsed, and there is no risk of causing partial collapse (collapse). In the above embodiment, the connection belt (22) is replaced by the following configuration. You can also do it. That is, columns made of synthetic resin or metal are erected at four corners (ridges formed by one side and another side adjacent to the side), and the columns are provided with It is also possible to fix the bottom part, the four side parts and the lid part.

[0031]

The net-like container of the present invention has a high strength, a particularly high flexural modulus, and an excellent shape-retaining property such as maintaining a box shape.

With this net-like container, the efficiency of the laying and arranging work can be improved, and a series of laying and laying work can be performed uniformly (uniformly). Further, in one construction, how many net-like containers are required can be grasped almost accurately in advance, and the cost for preparing extra net-like containers can be minimized.

Since the main body has a mesh shape, it can be folded. Further, for example, since it has excellent water permeability, it can be suitably used as a water-permeable civil engineering material, and can also be used as a civil engineering filter material.

When crushed stones are packed in a conventional net-like container,
The limit was 4 m ³ at most, but with the container of the present invention, it is possible to pack 6 m ³ or more.
