Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a retaining cage used for retaining earthworks and the like.

[Prior Art] In recent years, with the increase in land development, demand for earth retaining construction has rapidly increased. In such earth retaining work, earth retaining baskets called gabions are generally used, which are filled with natural stones, earth and sand, gravel, etc., and installed at predetermined locations.

Conventionally, such earth retention baskets were generally formed using diamond-shaped wire mesh, but because earth retention baskets made of diamond-shaped wire mesh are flexible, the surrounding surfaces may bulge and deform when filled with soil and stones. and the earth retaining function deteriorates,
Problems such as a large number of earth retaining baskets becoming irregularly arranged and spoiling the appearance of the slope occurred.

Therefore, recently, highly rigid welded wire mesh has been used to form earth retaining cages.
In the above-mentioned welded wire mesh, the vertical strands and the horizontal strands are not in the same plane, and one of them protrudes from the front side of the wire mesh and the other from the back side, which causes various inconveniences when configured as a retaining cage. was occurring. In other words, since the outer surface of the retaining basket is not flat, there is a risk that foreign objects such as materials may get caught in the protruding wires during installation, causing the wires to peel off and cause damage or deformation of the basket. It was hot. In addition, if multiple earth retaining baskets are installed side by side, if one of the earth retaining baskets is displaced due to changes in the ground, the vertical strands and vertical strands or horizontal strands that protrude between it and the adjacent earth retaining basket will be damaged. The strands and the horizontal strands engage with each other,
In some cases, the earth retaining baskets moved together, and the interlocking strands were peeled off or deformed, resulting in damage to the earth retaining baskets.

[Problems to be solved by the invention] The problem of the present invention is to make the outer surface of the retaining cage made of welded wire mesh flat so that foreign matter does not get stuck to the strands and the retaining baskets do not stick to each other. The purpose is to prevent the basket from being damaged by preventing entanglement and the like.

[Means for Solving the Problems] In order to solve the above problems, the present invention is formed by a welded wire mesh formed by welding vertical strands and horizontal strands to each other at their intersection points, and the welded wire mesh has the following features: A recess is provided at the intersection of at least one of the vertical strands or the horizontal strands, and by fitting the other strand into the recess, one of the wire mesh surfaces becomes a flat surface, and the flat wire mesh surface is turned outward. It is characterized by being arranged towards the

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

The retaining basket 10 shown in FIG. 1 includes a bottom net 10a,
Front net 10b, rear net 10c, left and right side nets 10
d, 10d, and a top mesh 10e, and each of the surface meshes 10a to 10e is constructed so as to be easily assembled by a wire mesh panel 11 made of welded wire mesh as shown in FIG. ing.

That is, the wire mesh panel 11 is made by welding vertical and horizontal strands 11a and 11b arranged in a lattice pattern together at their intersection points, and bending a ring 12 at the end of each strand 11a and 11b. At the intersection of both strands 11a and 11b, as shown in detail in FIG. 3, a recess 14 is provided in at least one of the strands, and the other strand is fitted into the recess 14. Both strands 11a and 11b are welded together in this state, thereby making one wire mesh surface 11c of the wire mesh panel 11 a substantially flat surface. In addition, the third
The figure shows a case where a recess 14 is formed in the horizontal strand 11a.

The depth of the recess 14 is preferably approximately the same as the diameter of the other wire when it is provided on only one wire, but it may be slightly shallower or deeper than that, and If the recess 14 is provided in both wires, it should be approximately 1/2 the diameter of the other wire.
It is best to set the depth to .

When forming the retaining basket 10 as shown in FIG. 1 using the wire mesh panels 11, a plurality of wire mesh panels 11 are placed on the flat wire mesh surface
1c facing outward in a box shape, and rings 12 formed on corresponding sides of adjacent wire mesh panels 11.
are positioned coaxially and a common connecting bone line 13 is inserted through these rings 12 to connect each wire mesh panel 11. Thereby, the wire mesh panels 11 can be connected only by using one connecting bone line 13 for each ridge. In this case, the mesh size can be changed for each surface mesh, for example, the front mesh 1
It is also possible to form the mesh of 0b larger than the mesh of the other surface meshes.

The earth retaining basket 10 is assembled and placed on a slope or the like as described above, and is installed in one or more stages by filling it with chestnut stone, gravel, earth and sand, etc. by an appropriate means. However, since the outer surface is formed as a flat surface, foreign objects such as materials and tools do not get stuck to the wire and cause it to peel or deform during installation work. Furthermore, even when a plurality of retaining cages are installed, adjacent cages will not become entangled with each other due to engagement of the strands.

In addition, when the material to be filled in the retaining basket 10 is smaller than the mesh of each surface mesh, especially the mesh of the front mesh 10b, such as gravel or earth, as shown in FIG. 4, at least the inside of the front mesh 10b is It is desirable to provide a support member 15 made of a material such as a wire mesh such as a crimp wire mesh with a small mesh, a synthetic resin net, wood, or bamboo to receive the filling material. in this case,
It is desirable that the lower end of the support member 15 be bent inward.

In addition, in order to prevent the front mesh 10b from bulging and deforming due to earth pressure, as shown in FIG.
and the rear screen 10c, between the front screen 10b and the bottom screen 1
Reinforcement wires A to C can also be stretched between each of the reinforcing wires A and 0a, and these reinforcing wires can be stretched alone or in combination.

Although the retaining basket of the above embodiment has the upper surface net 10e, this upper surface net 10e may be omitted depending on the installation conditions.

In the above embodiment, the earth retaining basket is constructed in such a manner that a surface mesh made of wire mesh panels is assembled using rings formed at the ends of the wires.
As shown in the figure, it goes without saying that surface meshes 20a to 20d made of wire mesh panels having no rings at the ends of the strands may be connected by appropriate connecting fittings 21.

[Effects of the invention] As described above, according to the present invention, the outer surface of the retaining basket made of welded wire mesh is made flat so that the wires constituting the wire mesh do not protrude outward. During the installation work of the soil retaining basket, foreign objects such as materials and tools do not get caught in the wire and cause it to peel or deform, and the installation work is very easy. Even if multiple earth retaining cages are installed, adjacent cages will not become entangled with each other due to the engagement of the wires, so even if one of the earth retaining baskets is displaced due to changes in the ground, etc. There is no possibility that adjacent earth retaining baskets will become entangled with each other and move together, or that interlocking strands will not peel off or deform, causing damage to the earth retaining baskets.
