Flip bucket for flood discharge of dam body of gravity dam
The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a flip bucket for gravity dam body flood discharge. The flip bucket comprises a side wall, a reverse arc curve section, a flip bucket body and a bottom plate. The two groups of side walls are arranged in parallel; the reverse arc curve section and the bottom plate are both arranged between the two sets of side walls and are sequentially connected to the water outlet end of the gravity dam. The working face of the flip bucket body is in a trapezoid shape, the flip bucket body is arranged in the middle of the bottom plate, the large end of the flip bucket body is connected with the water outlet end of the reverse arc curve section, and the working face of the flip bucket body is a downwards-sunken arc face. The flip bucket body in the flip bucket enables the nappe to have a good diffusion effect in the longitudinal direction and the transverse direction, and the nappe ejected from the bottom plate in advance and the nappe ejected from the flip bucket body to the far end form an approximately rectangular area, so that the water falling range of the nappe is increased, energy carried by discharged water flow in a water discharging building is fully eliminated, and the water discharging effect of the water discharging building is improved. Therefore, the threat to the stability of the release building is reduced.
本发明属于水利水电工程技术领域，具体涉及一种用于重力坝坝身泄洪的挑坎；其包括边墙、反弧曲线段、挑坎本体和底板；边墙有两组，两组边墙平行设置；反弧曲线段和底板均设置在两组边墙之间，反弧曲线段和底板依次衔接在重力坝的出水端；挑坎本体的工作面的形状为梯形，挑坎本体设置在底板的中部，挑坎本体的大端与反弧曲线段的出水端衔接，且挑坎本体的工作面为向下凹陷的弧面。该挑坎中的挑坎本体使水舌在纵向方向和横向方向均具有良好的扩散效果，且由底板提前出射的水舌与由挑坎本体向远端出射的水舌形成一个近似矩形的区域，使水舌的落水范围增加，以充分的消除泄水建筑中下泄水流携带的能量，从而减小对泄水建筑的稳定性的威胁。
