FISH REEF BLOCK FOR RIVERSIDE PROTECTION
To provide a fish reef block for riverside protection that can be installed as a part of a riverside protection block, and can create an optimal living space according to the type of an aquatic organism.SOLUTION: A fish reef block for riverside protection has a fish reef block body 11 of an oblong shape, assembled to a part of a riverside protection block 3 installed on a river 1. The fish reef block body 11 has a flowing water guide block 16 disposed inside from a front-side opening 11b, and a lid part 12 is attached to the opening 11b with a bolt 18. In the flowing water guide block 16, into the front part of the internal space of the fish reef block body 11, a flowing water is guided from the upstream side of the river, to from a living space S1 for an aquatic organism that likes the environment of flowing water. Behind the flowing water guide block 16, formed is a living space S2 for an aquatic organism that likes an environment of stagnant water. In the living spaces S1, S2, aquatic plants T and the like are disposed with a fixing member 17. On the upstream side of the lid part 12, a take-in channel 14 and a take-in guide 20 are provided to take in the flowing water W of the river, while on the downstream side of lid part 12, a take-out channel 15 and a take-out guide 21 are provided to take out the water inside to the downstream side of the river.SELECTED DRAWING: Figure 1
【課題】河川の護岸ブロックの一部として設置可能であり、水生生物の種類に応じて最適な棲み処空間を創出可能な護岸用魚礁ブロックを提供する。【解決手段】河川1に設置される護岸ブロック3の一部に組付けられる横長形状の魚礁ブロック本体11を備える。魚礁ブロック本体11は、前面の開口部11bから流水ガイドブロック16を内部に配置し、開口部11bにはボルト18で蓋部12を取り付ける。流水ガイドブロック16は魚礁ブロック本体11の内部空間の前部に河川の上流側から流水を導入して流水環境を好む水生生物の棲み処空間S1を形成する。流水ガイドブロック16の背後にはよどみ環境を好む水生生物の棲み処空間S2を形成する。棲み処空間S1,S2には固定部材17により水生植物T等を配置する。蓋部12の上流側に河川の流水Wを内部に導入する導水路14および導水ガイド20、蓋部12の下流側に内部の水を河川の下流側に導出する導出路15および導出ガイド21を設ける。【選択図】図１
