Technology for repairing floodplain fish habitat through channel improvement spur dike
The invention discloses a technology for repairing a fish habitat on a floodplain by utilizing a channel improvement spur dike, ecological spur dikes are built at the upstream and the downward moving position of a river channel, each ecological spur dike comprises a dike foundation, the dike foundation is built at the bottom of the river channel, the upper side of each dike foundation is fixedly connected with a dike body, and the lower side of each dike foundation is fixedly connected with a dam body. A first baffle and two second baffles are fixedly connected to the upper side of the dam foundation, one sides of the two second baffles are fixedly connected to the side walls of the two ends of the first baffle correspondingly, and the other sides of the two second baffles are fixedly connected to the side wall of the dam body. A gravel layer, a gravel layer and a sludge layer are sequentially and obliquely laid at the connecting corner of the dam foundation and the dam body from bottom to top. The ecological spur dike is reasonable in design and ingenious in conception, the inhabitation of the fishes on the floodplain can be better facilitated by building the ecological spur dike, and the inhabitation environment of the fishes on the floodplain in a channel river is improved.
本发明公开了一种利用航道整治丁坝修复河漫滩鱼类栖息地的技术，将生态丁坝建造在河道的上游和下移处，其中所述生态丁坝包括坝地基，所述坝地基建造在河道的河底，所述坝地基的上侧固定连接有坝体，所述坝地基的上侧固定连接有第一挡板和两个第二挡板，两个所述第二挡板一侧分别固定连接在第一挡板的两端侧壁上，两个所述第二挡板的另一侧固定连接在坝体的侧壁上，所述坝地基与坝体的连接拐角处从下往上依次呈倾斜状铺设有碎石层、砂砾层和淤泥层。本发明设计合理，构思巧妙，通过建造生态丁坝，可以更加有利于河漫滩鱼类的栖息，改善了航道河流中河漫滩鱼类栖息环境。
