Single-outlet fishway utilizing tail water of ecological unit and fish passing method
The invention provides a single-outlet fishway utilizing tail water of an ecological unit and a fish passing method. A fishway downstream shallow water section, a fishway overflow section and a fishway upstream deep water section which are communicated are sequentially arranged from downstream to upstream; a fishway inlet rectification building is installed in the outer side area of the fishway inlet; the fishway overflow section is a transition section of the fishway upstream deep water section and the fishway downstream shallow water section and used for adjusting the water level of the fishway upstream deep water section and the water level of the fishway downstream shallow water section so that water flow of the fishway upstream deep water section and water flow of the fishway downstream shallow water section can be smoothly connected and transited. The fishway inlet uses the tail water of the ecological unit and the abandoned water of the fishway overflow section to attract fishes; the fishway outlet is a single outlet, the problem that a plurality of fishway outlets need to be arranged when a fishway inlet complex water supplementing system is constructed and the upstream high water level amplitude changes is solved, gate-free control over fishway operation is achieved, meanwhile, the shallow water section fishway adopts the low side wall, fishway construction investment is further saved, and the construction cost is reduced. And the fishway operation management level and the fish passing efficiency are improved.
本发明提供一种利用生态机组尾水的单出口鱼道及过鱼方法，自下游至上游依次设置连通的鱼道下游浅水段、鱼道溢流段和鱼道上游深水段；在鱼道进口的外侧区域安装鱼道进口整流建筑物；鱼道溢流段为鱼道上游深水段和鱼道下游浅水段的过渡段，用于调整鱼道上游深水段和鱼道下游浅水段的水位，使鱼道上游深水段与鱼道下游浅水段水流平顺衔接过渡。本发明鱼道进口利用生态机组尾水和鱼道溢流段的弃水诱鱼；鱼道出口采用单一出口，解决了鱼道进口复杂补水系统建设和在上游高水位变幅时必须设置多个鱼道出口的难题，实现了鱼道运行的无闸门控制，同时浅水段鱼道采用矮边墙，进一步节省了鱼道建设投资，提高鱼道运行管理水平和过鱼效率。
