Description

  The present invention relates to a connecting device for connecting adjacently arranged gabions to each other.

  For example, as described in Patent Document 1, gabion is generally used when building a revetment wall on the shore such as a coast, a river bank, a lake shore, or building a reinforcement wall on a slope. These gabions are formed into a rectangular container shape or cylindrical shape with a rhombus wire mesh, and are lined up and down, left and right along the shoreline and slope, and stacked up and down, with the chestnut filled inside. Accordingly, retaining walls such as the revetment wall and the reinforcing wall are constructed. At that time, in order to prevent the position shift of the gabions and increase the strength of the retaining wall, the adjacent gabions are connected to each other by an appropriate method.

  The connection between the gabions is generally performed by a method of binding the frame lines attached to the edges of the gabions with a wire, or bundling the rhombus metal mesh row lines with a wire. .

  However, the method of binding the frame lines or the column lines with the wire in this way has to be performed by inserting the wire into the gabion mesh and winding it around the frame line or the column line. It takes time and effort. In addition, when a force in the direction of relative displacement is applied between the gabions that have become heavy due to the stuffing of stone, a strong force acts locally on the frame line and the row line bound by the wire. The frame line and the column line are greatly deformed or broken, and the gabion is easily damaged.

On the other hand, in Patent Document 2, a connecting rod is inserted into a stone-padded gabion so that both ends protrude across the gabion and both ends protrude outside the gabion, and the coupling rods of adjacent gabions are connected to each other. Are disclosed in which the gabions are connected to each other by being connected to each other.
However, this is to hold the connecting rod between the chestnuts filled in the gabion, so that the position of the connecting rod may change due to the displacement of the chestnuts. There is a problem that the connected state is not stable.
