Combined flood discharge and energy dissipation structure suitable for narrow deepwater cushion pond
The invention belongs to the technical field of flood discharge and energy dissipation in water conservancy and hydropower engineering, and particularly discloses a combined flood discharge and energy dissipation structure suitable for a narrow deepwater cushion pond, which comprises a release structure body, and the release structure body comprises a surface hole side wall, a common side wall and a bottom hole side wall; the bottom of the surface hole comprises a surface hole reverse arc curve section and a surface hole bottom plate straight line section, the surface hole reverse arc curve section is smoothly connected with the flip bucket after reaching the lowest point, the flip bucket part of the surface hole reverse arc curve section is provided with a surface hole inclined surface section inclined towards the bottom hole direction, the surface hole inclined surface section forms a straight line low ridge, and the surface hole inclined surface section is located on the side close to the bottom hole; the bottom of the bottom hole comprises a bottom hole bottom plate linear section and a bottom hole reverse arc curved surface section, and the two sides of the bottom hole reverse arc curved surface section are turned over towards one side of the surface hole to form a height difference so that the bottom hole ejection nappe can be turned over inwards. The nappe can be dispersed as much as possible, scouring damage of the nappe to a downstream riverbed and a bank slope is reduced, emergent water flows do not affect one another, and a good nappe dispersing effect is achieved during independent operation.
本发明属于水利水电工程中泄洪消能技术领域，具体公开了一种适用于窄深水垫塘内的联合泄洪消能结构，包括泄水建筑物本体，泄水建筑物本体包括表孔边墙、共用边墙和底孔边墙；表孔的底部包括表孔反弧曲线段和表孔底板直线段，孔反弧曲线段达到最低点后平顺衔接挑坎，表孔反弧曲线段的挑坎部分设有向底孔方向倾斜的表孔斜面段，表孔斜面段形成直线低坎，表孔斜面段位于靠近于底孔一侧；底孔的底部包括底孔底板直线段和底孔反弧曲面段，底孔反弧曲面段的两侧向表孔一侧翻转形成高差使底孔出射水舌向内翻转。本发明能够尽可能的分散水舌，减小水舌对下游河床及岸坡的冲刷破坏，而且出射水流互不影响，单独运行时也有很好的分散水舌效果。
