Spur dike with multiple ecological functions
The invention provides a spur dike with multiple ecological functions, and relates to the technical field of water conservancy and hydropower ecological protection, the spur dike comprises a river channel, a branch dam is arranged in the river channel, a fishway is arranged on one side of the branch dam, and a plurality of rows of parallel ecological spur dikes are arranged on a bank slope on the same side of the downstream end of the fishway; the ecological spur dike is arranged in the range of the return water change line and comprises a dam root connected with the bank slope, a dam body is arranged on the side, away from the bank slope, of the dam root and evenly divided into a plurality of layers in the water flow height direction, each layer is arranged in a turning plate mode, and ecological matrixes are arranged on the surfaces of the turning plates. In the fish breeding period, the turnover structure is opened to form a migration channel, fishes are assisted in finding a proper migration route and a fishway inlet in the downstream river reach close to the fishway side, and the fish migration dam passing efficiency is improved; in the non-fish breeding period, the overturning structure is closed, the water blocking, water controlling and flow adjusting effects of the spur dike continue to be achieved, and the inhabiting conditions with rich and diversified water flow are provided for the fishes in the local space.
本发明提供了一种具备多生态功能的丁坝，涉及水利水电生态保护技术领域，技术包括河道，河道内设置有支流大坝，支流大坝的一侧设置有鱼道，所述鱼道下游端同侧的岸坡上设置有若干排平行设置的生态丁坝，且生态丁坝布置在回水变动线范围内，生态丁坝包括与岸坡连接的坝根，坝根远离岸坡的一侧设置有坝身，坝身沿水流高度方向均匀划分为若干层，每层呈翻板设置，翻板的表面设置有生态基质。当鱼类繁殖期间，打开翻转结构形成洄游通道，辅助鱼类在靠鱼道侧的下游河段找到适宜的洄游路线和鱼道进口，增加鱼类洄游过坝的效率；当非鱼类繁殖期间，关闭翻转结构，继续发挥丁坝的阻水控水调流作用，在局部空间为鱼类提供水流丰富多样的栖息条件。
