Diversion tunnel outlet vertical shaft energy dissipation structure
The invention relates to a diversion tunnel outlet vertical shaft energy dissipation structure which comprises a vertical shaft, a flow inlet section and a diversion tunnel, a bottom plate is arranged at the bottom of the vertical shaft, the bottom of the vertical shaft is of a closed structure, a flow inlet and an overflow opening are formed in the shaft wall of the vertical shaft, one end of the flow inlet section is communicated with the flow inlet, and the other end of the flow inlet section is communicated with the diversion tunnel. The center line of the flow inlet in the width direction and the vertical axis of the vertical shaft have an eccentric distance, and the bottom elevation of the overflow port is between the elevation of a bottom plate of the flow inlet section and the elevation of a top plate of the flow inlet section. The structure is simple, construction is convenient, kinetic energy of drainage water flow of the diversion tunnel can be fully eliminated, the unit width flow of the drainage water flow can be reduced, complementary energy can be dispersed, the water flow is guided to the middle of a downstream river channel, and the load of a bank slope and the bank side flow speed are reduced.
本发明涉及一种导流洞出口竖井消能结构，包括竖井、进流段、导流洞，所述竖井的底部设置有底板，竖井的底部为封闭结构，所述竖井的井壁上设置有进流口和溢流口，所述进流段的一端与进流口连通，进流段的另一端与导流洞连通，进流口宽度方向的中心线与竖井的竖向轴心线有偏心距，所述溢流口的底部高程介于进流段底板高程与进流段顶板高程之间。本发明结构简单，施工方便，能够充分消除导流洞下泄水流的动能，且可以降低下泄水流的单宽流量，分散余能，将水流导向下游河道的中部，减小岸坡的荷载和岸边流速。
