である。[Detailed description of the invention] This invention relates to an assembled fish nest structure in concrete sheet piles. Conventionally, this type of river revetment involves constructing waterway wall revetments by placing concrete sheet piles of the same shape in parallel into the ground, and the reality is that fish and shellfish habitats are being lost due to river improvements. be.

矢板３の突縁部５に貫通穴６を設ける。 An embodiment of this invention shown in the drawings will be described below. Concrete sheet piles 1 have protruding edges 5 on both sides of the flat plate part 4 at right angles to the flat plate part 4, and are poured into the ground in parallel in succession, and are optionally placed in the river bed at the location where a habitat for fish and shellfish is to be created. A sheet pile 2 with a through hole 6 provided in an upper flat plate part 4 is installed together, and the flange part 5 of the sheet pile 2 which becomes a fish nest is abutted against the flange part 5 of the sheet pile 3, and is driven into the ground. The space above the combined sheet piles 2 and 3 facing each other is covered with a top plate 7. In addition, the top plate has protrusions 8 as shown in the example of Fig. 4. In Fig. 5, there is a stepped plate 9.
A tightening bolt through hole 10 is provided in the sheet pile and bolt 11.
It was fixed at. In this embodiment shown in Fig. 6, a through hole 6 is provided in the ridge 5 of the sheet pile 3.

来るなどの諸効果がある。 This invention has the above-mentioned structure and is easy to assemble, reduces construction costs through standardization, maintains the finished appearance, and can be constructed rationally. By providing a protrusion on the top slab, it is possible to prevent the top slab from shifting, and by using a stepped slab, it can partially serve as the formwork for the on-site cast concrete. Further, by providing a through hole in the ridge, there are various effects such as increasing the volume of the fish nest and making it possible for fish to swim.
