Flood discharge channel and fishway combined system
The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a flood discharge channel and fishway combined system which is arranged on a side bank of a river sluice dam and comprises an upstream combined section, a middle connecting section and a downstream separation section. The upstream joint section is provided with a trapezoid joint water channel, and a flow slowing stop block used for semi-shielding water flow is arranged in the trapezoid joint water channel. The trapezoidal combined water channel is used for flood discharge and fish migration; the middle connection section comprises a water inlet transition section, a connection section, a lock chamber section and an overflow transition section which are sequentially arranged in the water flow direction. The downstream separation section comprises a downstream flood discharge channel and a downstream fishway; and the downstream flood discharge channel and the downstream fishway are respectively communicated with the flood discharge open channel and the migration open channel. According to the scheme, the flood discharge channel and the fishway are arranged in a combined mode, integrated design or separated design is carried out according to terrain, geological conditions, functional requirements and the like, the middle part is connected through the connecting section, and the functional requirements of the flood discharge channel and the fishway are synchronously guaranteed.
本发明属于水利水电工程技术领域，具体涉及一种泄洪渠与鱼道联合系统，设置于拦河闸坝的侧岸处，并包括上游联合段、中部联结段和下游分离段；所述上游联合段具有梯形联合水道，该梯形联合水道内设置有用于对水流进行半遮挡的缓流挡块；该梯形联合水道用于泄洪和鱼类的洄游；所述中部联结段包括沿水流方向依次设置的进水渐变段、衔接段、闸室段和溢流渐变段；所述下游分离段包括下游泄洪渠和下游鱼道；下游泄洪渠和下游鱼道分别连通于泄洪明渠和洄游明渠。本方案将泄洪渠和鱼道进行联合布置，根据地形、地质条件及功能需求等进行一体式设计或分离式设计，中间部分采用联结段进行衔接，以同步保障泄洪渠和鱼道功能需求。
