生じて土留機能を消失し易い。[Prior Art] In recent years, with the increase in land development, the demand for earth retaining construction has rapidly increased. In such layered construction, multiple box-shaped gabions 1 are used in a stacked manner, as shown in Figure 4, but this is not suitable for use on soft ground where there is a risk of undue subsidence, or on ground that is likely to be washed away due to water damage. In this case, each gabion 1 is relatively moved or tilted due to changes in the ground, causing displacement, deformation, damage, etc. of the upper and lower gabions, and the earth retaining function is likely to be lost.

損ねることになる。 In addition, the impact force when filling the gabion 1 with earth and stones,
The side surfaces of each gabion tend to bulge and deform due to earth pressure after filling, which may lead to damage to the gabion. Moreover, since the front surface 2 of each gabion 1 is exposed to the outside, deformation of the front surface 2 will significantly impair the appearance.

［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.

第１図に示す蛇籠組立体は、箱形をなす複数の
蛇籠１１によつて構成されている。 The gabion assembly shown in FIG. 1 is composed of a plurality of box-shaped gabions 11.

上記蛇籠１１は、第２図に詳細に示すように、
底面網１２と前面網１３、後面網１４、及び左右

に応じて上面網（図示せず）が取付けられる。 As shown in detail in FIG. 2, the gabion 11 has the following features:
It includes a bottom screen 12, a front screen 13, a rear screen 14, and left and right side screens 15, 15, to which a top screen (not shown) is attached as necessary.

同士が適宜方法によつて互いに連結されている。 Each of the above-mentioned surface meshes 12 to 15 is formed independently of a welded wire mesh formed by welding the vertical strands 17 and the horizontal strands 18 at their intersections, and the adjacent surface meshes are connected in an appropriate manner. Therefore, they are connected to each other.

ない。 At least the vertical meshes of the gabion 11, that is, the front mesh 13, the rear mesh 14, and the left and right side meshes 15, 15, are made of welded wire meshes made of vertical strands, as shown in FIG. A recess 19 is provided in the recess 17 by bending, and the horizontal wire 18 is inserted into the recess 19.
If the structure is such that the horizontal strands 18 are welded and integrated with the vertical strands 17 in a state where they are fitted together, the impact force that acts downward or diagonally downward on the lateral strands 18 during or after filling with earth and stone can be avoided. For acting forces such as earth pressure, etc.
It is possible to increase the engagement force of the horizontal strands 18 and prevent their separation. In this case, by locating the horizontal strands 18 inside the gabion, the above peeling prevention effect can be further enhanced. Of course, bottom net 1
It goes without saying that 2 may be constructed of a similar wire mesh.

補強線２１が張設される。 As shown in FIG. 1, the above-mentioned gabions 11 are stacked up and down in multiple stages with their positions slightly shifted back and forth, and the upper end of the front mesh 13 in the upper gabion 11 and the rear mesh in the lower gabion 14 are connected to each other by a reinforcing wire 20 made of wire or the like. In this case, in the lowermost gabion 11, a similar reinforcing wire 21 is stretched between its own front net 13 and bottom net 12 as necessary.

と鎖線で示す補強線とを両方取付けてもよい。 These reinforcing wires 20 and 21 can be easily connected by forming a ring at both ends or at a predetermined position on each surface mesh, and using this ring.
An appropriate number of reinforcing wires 20 and 21 can be attached at intermediate positions or both ends in the length direction of the front net 13, and the tips of the reinforcing wires 20 and 21 are connected to the height of the front net 13, as shown by chain lines in FIG. The reinforcing line shown in solid lines and the reinforcing line shown in dashed lines may both be connected at an intermediate position in the direction.

立体が設置される。 In constructing the gabion assembly, the lower gabion 11 is first placed in a predetermined position, and earth and sand, stones, etc. are filled therein. Subsequently, the upper gabion 11 is stacked on top of it with shifted positions back and forth, and after the upper and lower gabions 11, 11 are connected to each other by the reinforcing wire 20, the upper gabion 11 is similarly filled with earth and stones. be done. Then, the gabion assembly described above is installed by repeating the same operation and stacking each gabion 11 in layers.

好に保持される。 In addition, if movement of the slope or erosion occurs, each gabion 11 will move or tilt accordingly, but since the upper and lower gabions are connected by the reinforcing wire 20, each gabion 11 will not come apart. There is no large relative movement, and the earth retaining function is maintained well.
