Concave special-shaped stilling pool
The invention discloses a concave special-shaped stilling pool, belongs to the technical field of flood discharge and energy dissipation in water conservancy and hydropower engineering, and solves the problem of insufficient energy dissipation of an existing stilling pool. The side walls on the four sides of the stilling pool are an upper side wall on the upstream side, a lower side wall on the downstream side, a left side wall on the left bank side and a right side wall on the right bank side respectively, the top of the upper side wall is a differential flip bucket, and the upper side wall, the left side wall and the right side wall are each provided with at least one A-shaped groove protruding in the upstream direction, the left bank direction and the right bank direction. The top of the lower side wall is provided with a water outlet inclined face inclining upwards in the water flow direction, the lower side wall is further provided with at least one stage of B-type groove protruding towards the downstream direction, and a water falling area of a bottom plate of the stilling pool is provided with at least one stage of C-type groove. The energy of water flow in the stilling pool is weakened, the pulsating pressure of a bottom plate and the flow speed near the bottom are reduced, the scouring effect of the water flow is relieved, and the phenomena of secondary hydraulic jump of the water flow out of the pool, uneven transverse flushing water flow and the like are eliminated.
本发明公开了一种内凹式异型消力池，属于水利水电工程中的泄洪消能技术领域，解决现有消力池消能不充分的问题，采用的技术方案是：内凹式异型消力池，消力池四侧的边墙分别为上游侧的上边墙、下游侧的下边墙、左岸侧的左边墙和右岸侧的右边墙，上边墙的顶部为差动式挑坎，上边墙、左边墙和右边墙均设置至少一级分别凸向上游方向、左岸方向和右岸方向的A型凹槽，下边墙的顶部设置沿水流方向倾斜向上的出水斜面，下边墙还设置至少一级凸向下游方向的B型凹槽，消力池的底板的落水区设置至少一级C型凹槽。本发明削弱了消力池内水流能量，降低了底板脉动压力和临底流速，减轻了水流的淘刷作用，消除了出池水流二次水跃及不均匀横向折冲水流等现象。
