TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a gabion gabion used for revetment work on rivers, coasts, and the like, residential land construction work, playground construction work, and the like.

[Prior art]
2. Description of the Related Art Conventionally, this kind of assembled gabion is formed entirely of a diamond-shaped wire mesh, and is installed at a site in a state where the inside is packed with stones. However, since this prefabricated gabion is entirely made of diamond-shaped wire mesh, its flexibility is great, and the surrounding surface is greatly swelled and deformed by stuffing, so that many gabions are exposed on the slope formed on the front surface. When it is installed in such a way that it does not deform, it is most easily deformed because its front surface is not supported from the outside. For this reason, many gabions are irregular, the height of the gabion is reduced by the amount of deformation, and the upper gabion sinks or tilts, so that the slope is easily cluttered, and the appearance of the created slope is significantly impaired. There was a problem.
[0003]
On the other hand, as shown in Patent Literature 1, for example, there is known an assembled gabion having a trunk net formed of a flexible diamond-shaped net and a lid net formed of a rigid welded net. . According to this gabion, since the trunk net is formed of a flexible diamond-shaped net, it is easily deformed according to the unevenness of the ground, so that the installation is stably performed, and the lid net is made of a rigid net. Because it is formed by a certain welding wire net, it is difficult for the swelling deformation of the lid net due to the filling of earth and sand or rubble to occur. However, in the case of this gabion, although the lid mesh on the front and rear surfaces is higher in rigidity due to the welded wire mesh, the bulging deformation on the side face is still not eliminated because the side face is a flexible rhombus wire mesh, and the above-described problem remains. It is. Furthermore, since this gabion uses a lot of expensive diamond-shaped wire nets, there is a problem that the cost of the gabion increases accordingly.
[0004]
Further, as another gabion, for example, as shown in Patent Document 2, the bottom net and the top net are formed by a rigid wire net such as a welded wire net, and at least one of the front, rear, left and right side nets is a diamond wire net or the like. 2. Description of the Related Art It is known that a flexible wire mesh is formed and the remainder is formed by a rigid wire mesh. According to this gabion, it is good if the installation surface is flat, but if the installation surface has some bumps or small rocks, there is a problem that the installation becomes unstable because the bottom surface is not flexible. .
[0005]
Further, the gabion shown in Patent Document 1 described above is provided with a ring at each of the striated ends of the corresponding sides in the connection of the welding wire mesh and the diamond wire mesh, and the two are connected by inserting a common connecting bone line into each ring. are doing. However, according to this connection method, it is necessary to provide a ring on both the welded wire mesh and the diamond wire mesh.In particular, providing a ring on the diamond wire mesh as compared with the welded wire mesh takes time and, therefore, reduces the cost of the diamond wire mesh. There is a problem that it is more expensive. Further, the welding wire mesh has high rigidity and very low flexibility, so that it may be difficult to handle it.

FIG. 1 is a partially exploded perspective view of an assembled gabion, and FIG. 2 is a partially enlarged view of a connecting portion of a welded gauze and a diamond-shaped gauze of the assembled gabion. The assembling gabion 10 is a rectangular parallelepiped basket in which front and rear and left and right side nets 11 to 14, a bottom net 15 and a top net 16 are combined, and is used by being filled with earth and sand or gravels. The side nets 11 to 14 are formed of a welded wire netting in which steel wires arranged in a row are fixed by welding, and the bottom net 15 and the top net 16 are formed of a rhomboidal net obtained by knitting steel wires into a rhombus. I have. As the steel wire, for example, a zinc aluminum alloy-plated iron wire that is a round wire having a circular cross section is used.
