However, although the structure using sandbags is suitable for temporary construction, there is a concern that the sandbags will be damaged due to deterioration over time and the internal earth and sand will leak, making it unsuitable for long-term use, and when it is no longer needed. , It was also difficult to remove.

On the other hand, a futon basket that can be used for a long period of time is known to be used for filling stones inside, but there is a drawback that the stone filling work at the site is complicated and cannot be used for curved parts. ..

There are also cylindrical stone baskets (for example, Patent Documents 2 and 3) for the box-shaped futon basket. Further, a columnar wire mesh cage (for example, Patent Document 4) having improved workability by dividing the members has been proposed. In this columnar wire mesh cage, the columnar wire mesh body is composed of a pair of semi-cylindrical wire mesh bodies, and the columnar wire mesh body is formed. One end of the wire mesh is closed with a metal lid, and a connecting coil metal wire is wound around the vertical metal wires of the pair of semi-cylindrical wire mesh bodies to connect the semi-cylindrical wire mesh bodies.
