る。[Means for Solving the Problems] Therefore, the present invention has been proposed in order to solve the above-mentioned drawbacks, and has a structure in which a bottom plate, a back plate, and an upper plate are formed in a U-shaped cross section. A plate with a narrower width than the back plate is provided at a certain distance from the plate, and a large number of long holes are formed in this.
A partition plate is provided toward the front from both sides thereof, and a large number of insertion holes are provided in front of the partition plate, and these insertion holes are provided at the same horizontal position on the left and right. In order to construct this, side surfaces are butted against each other on the foundation of the shore of the river, and the rod is inserted into the insertion hole, and stones such as rocks and cobblestones are filled inside. By doing so, at the same time as protecting the shore, relatively large fish can live in the space between the backboard and the partition, and small fish can live between the stones, making it a good evacuation site and breeding. Is also effective.

ものである等の効果を奏するものである。"Effect of the Invention" The present invention is installed on the shore of a river, protects the shore, and forms a space (6) between the back plate (2) and the partition plate (4). A relatively large fish inhabits this part, and the gap between the partition plate (4) and the stone (13) filled between the rods (12) inserted in the insertion holes (8) is relatively large. A small space is formed in which small fish live, and small fish are not attacked by large fish.
In addition, the space becomes a shaded area, and it also serves as an evacuation site, so that it can be safely inhabited without being attacked by external enemies, and it is also useful for breeding. Further, by using wood for the rod (12), the surface of the concrete can be covered up, and a landscape close to nature can be created, which is an effect of environmental conservation.
