Flood discharge and energy dissipation structure for high dam
The flood discharge and energy dissipation structure for the high dam comprises at least three surface hole flow channels arranged side by side and a plunge pool arranged at the downstream positions of the surface hole flow channels, and partition walls are arranged on the two sides of each surface hole flow channel; the tail ends of the two surface hole flow channels located on the outermost side are each provided with a first depression angle section inclining downwards, and the tail ends of the surface hole flow channels located on the inner side are each provided with a second depression angle section inclining downwards. The two sides of the first depression angle section are each provided with a first side wall, and the first side walls are obliquely arranged outwards in the water flow direction. Second side walls are arranged on the two sides of the second depression angle section, and the second side walls are obliquely arranged towards the inner side in the water flow direction; the first side wall and the second side wall are connected with the partition wall corresponding to the upstream position. According to the flood discharge and energy dissipation structure, the technical problems that the engineering cost is high and arrangement is limited in underflow energy dissipation and the flood discharge atomization influence range and degree are large and the fluctuation of tail water of a power station is large in common flip flow energy dissipation arrangement are solved.
本发明公开了一种用于高坝的泄洪消能结构，其包括至少三条并排设置的表孔流道以及设置在表孔流道下游处的水垫塘，表孔流道两侧均设置隔墙；位于最外侧的两条表孔流道的末端处均设有向下倾斜的第一俯角段，位于内侧的表孔流道的末端处均设有向下倾斜的第二俯角段；第一俯角段的两侧均设有第一侧边墙，该第一侧边墙均沿水流方向向外倾斜设置；第二俯角段的两侧均设有第二侧边墙，该第二侧边墙均沿水流方向向内侧倾斜设置；第一侧边墙和第二侧边墙均与上游处所对应的隔墙相连。本发明的泄洪消能结构解决了底流消能存在的工程造价高、布置受限的不足及常用挑流消能布置存在的泄洪雾化影响范围及程度大、对电站尾水波动大的技术问题。
