Control method of flow direction of slot sill nappe shock wave streams and slot sill
The invention discloses a control method of the flow direction of slot sill nappe shock wave streams and a slot sill. The slot sill comprises a slot sill bottom plate and side walls arranged on the two sides of the slot sill bottom plate respectively. The side walls comprise shrinking side wall bodies. A triangular pyramid frustum body is arranged on the side wall on the weak slot sill nappe shock wave side, the bottom surface of the triangular pyramid frustum body is located on the slot sill bottom plate, the top surface of the triangular pyramid frustum body is flush with the top of the corresponding side wall, and a pair of adjacent side faces of the triangular pyramid frustum body overlap the corresponding shrinking side wall body and the cross section of the outlet of the slot sill respectively. The triangular pyramid frustum body on the weak slot sill nappe shock wave side is used for improving the intensity of slot sill nappe shock waves on the weak slot sill nappe shock wave side so that the slot sill nappe shock waves on the two sides of the slot sill can be opposite in intensity, and the two shock wave streams can flow straight downwards after converging. According to the control method and the slot sill, the adverse flow state of deviating to the bank side of the slot sill shock wave streams can be reduced under different incoming flow conditions, and the problem that nappe shocks the bank slope is solved.
