Energy dissipation and flow state adjustment structure for water flow to flow into river channel

The invention discloses an energy dissipation and flow state adjustment structure for water flow converging into a river channel. The energy dissipation and flow state adjustment structure comprises a tunnel water outlet, a slope connecting section, a stilling pool and a plurality of flow guide piers. One end of the tunnel water outlet is connected with the tunnel, the other end of the tunnel water outlet is connected with the slope top of the slope connecting section, and the slope bottom of the slope connecting section is connected with the stilling pool; the plurality of flow guide piers are arranged in the stilling pool; the stilling pool is a deep digging type stilling pool. After flowing out of the tunnel through the tunnel water outlet, water flow enters the deep digging type stilling pool in the river channel for energy dissipation, and the flow guide pier is arranged in the stilling pool for further energy dissipation of the water flow; besides, in order to avoid the situation that high-speed water f
