In this way, an earth-retaining wall for a shore, having a protruded or recessed shape with a small radius can be freely constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basket mat for constructing a retaining wall on the shore of a lake or river.

[0002]

2. Description of the Related Art As a conventional basket mat of this kind, for example, as shown in Japanese Patent Laid-Open No. Hei 7-189229,
It has a flat rectangular shape, and the individual basket mats are arranged along the shore, and are sequentially retracted so as to be stacked in a stepwise manner.

[0003]

Since the conventional cage mat has a flat rectangular shape, it is convenient to construct a straight retaining wall, but it is inconvenient to construct a curved portion. . In other words, when constructing a retaining wall whose shore is curved concavely or convexly, the adjacent cage mats are curved concavely or convexly with a gap at the rear or front side between adjacent cage mats. I am trying to do it.

[0004] In this case, there is no problem if the shore has a gentle curvature. However, when the shore is constructed in a small arc shape, a large gap is generated between adjacent cage mats, and it is difficult to construct the shore. It turned out to be bad for the scenery.

[0005] When the shore is constructed in a straight line, the construction is simple as described above, and the shore is literally straight. And it had to be a shore that was not appreciated by underwater creatures.

The present invention has been made in consideration of the above, and it is possible to easily form a retaining wall of a shore having a small uneven shape with a small radius. It is an object of the present invention to provide a basket mat that can be made to recharge the natural environment on an artificial shore.

[0007]

In order to achieve the above object, a basket mat according to the present invention comprises a front wall, left and right side walls and a rear side wall, each of which is formed in a net shape, and a space formed by these. By connecting the bottom wall and the top wall that closes up and down,
In the basket mat in which the filling material is inserted, the front wall has a convex arc shape, the length of the rear wall is shorter than the length of the front wall, and the plane shape is a convex arc on the front surface, and both side surfaces are formed. Has a configuration tapered toward the rear end.

In the basket mat described above, the left and right side walls are bent, and parallel portions facing each other are provided in a front portion connected to the front side wall. The length of the basket mat in the front-rear direction is smaller than the width of the front surface.

[0009]

[Operation] Retaining walls on the banks of lakes and rivers are constructed by arranging each cage mat adjacent to each other. At this time, a triangular gap is formed on the rear side of the adjacent cage mats, and the gap is filled with miscellaneous stones and earth and sand and fixed. In this part, the plants are grown and are easily greened. In addition, a straight retaining wall is constructed by arranging the tops of the front side walls of each basket mat in a straight line, but the shore at this time has irregularities due to the convex arc shape of the front surface of each basket mat, Water stagnation is formed in each recess.

[0010] In addition, each cage mat is arranged so as to have a convex arcuate curvature on the front surface thereof, whereby a convex retaining wall having a smooth arc is constructed. Also, the convex arcuate retaining wall larger than the curvature of the front surface has a convex arc shape on the front surface of each cage mat, so that a retaining wall that can give a substantially arcuate impression is constructed.

[0011]
