Flood control structure for hydropower station
The invention discloses a flood control structure for a hydropower station, and relates to the technical field of hydropower station flood control. A flood control structure for a hydropower station comprises a flood control dam, a buffer dam is arranged on the flood control dam in the upstream direction of a river channel, an energy dissipation embankment is arranged on the side, facing the upstream, of the buffer dam, the energy dissipation embankment is arranged in a riverbed through a plurality of reinforcing piles arranged at the bottom, and the energy dissipation embankment and the buffer dam are connected through a connecting bridge. A deceleration protruding block is laid on the top of the connecting bridge. The influence of the flood on the downstream is reduced through three modes of overflowing, energy dissipation and water potential impact energy dissipation, the impact of the water potential on the downstream is reduced through gradual energy dissipation, the influence of the flood on the downstream is reduced, and the impact of the water potential on the flood control dam is reduced through double-layer energy dissipation and blocking of the flood control dam; damage of the flood to the flood control structure can be reduced, impact of the flood to the downstream can be reduced, and flood harm can be reduced through multiple insurance measures.
本发明公开了一种水电站用防洪结构，涉及水电站防洪技术领域。一种水电站用防洪结构，包括防洪坝，所述防洪坝朝向河道上游方向设置有缓冲坝，缓冲坝朝向上游一侧设置有消能堤，消能堤通过底部设置的多个加固桩设置于河床之内，消能堤与缓冲坝之间通过连接桥相连接，连接桥顶部铺设有一面减速凸块。本发明通过溢流、消能和水势冲击消能三种方式减少洪水对下游造成的影响，通过逐步的消能，减少水势对下游的冲击，降低洪水对下游的影响，以双层消能和防洪坝的阻拦降低水势对防洪坝的冲击，既能够减少洪水对该防洪结构的损伤也能够降低洪水对下游的冲击，也能够以多重的保险措施，减少洪水危害。
