ねるなどの問題を生じることがあつた。 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.

ことがあつた。 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.

It is characterized by being arranged towards the
[実施例]
以下、本考案の実施例を図面に基づいて詳細に
説明する。[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

金網面11cを略平坦面としている。なお、第3
図は、横素線11aに凹部14を形成した場合を
示している。 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.
上記凹部14の深さは、それを一方の素線のみ

の深さにするのが良い。 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 .

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.

ことがない。 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.
