Differential mixed energy dissipation structure for slope diffusion

Abstract

The invention provides a differential mixed energy dissipation structure for slope diffusion. The differential mixed energy dissipation structure comprises an arc-shaped sluice chamber section, a differential mixed energy dissipation station, slope diffusion structures and lateral joining sections. The head end of the differential mixed energy dissipation station is connected with the outlet end of the arc-shaped sluice chamber section, and the lateral joining sections are arranged on the two sides of the arc-shaped sluice chamber section. The slope diffusion structures are arranged on the twosides of the differential mixed energy dissipation station and connected with the downstream ends of the lateral joining sections. According to the differential mixed energy dissipation structure, the structure is simple and practical, construction is convenient and rapid, and the effect is remarkable by combining free diffusion energy dissipation with differential mixed energy dissipation; and compared with a conventional energy dissipation station, wing walls and other foundation treatment structures thereof can be omitted, overall arrangement is concise and elegant, and the engineering construction time and investment are saved greatly.

Description

technical field [0001] The invention relates to an energy dissipation structure, in particular to a slope diffusion differential hybrid energy dissipation structure, which can combine the differential hybrid energy dissipation with the slope diffusion free outflow. Background technique [0002] The energy dissipation structure is one of the main structures of the sluice. The function of the energy dissipation structure is often through the turbulent diffusion and friction inside the water flow, the diffusion of the water flow in the air and the strong mixing with the air, the friction and collision between the water flow and the side wall, etc. The physical effect is realized. At present, the energy dissipation structure usually adopts the ordinary deep excavation type energy dissipation structure. Both sides of the stilling pool adopt high wing wall structure, which is difficult to construct, and the foundation treatment of the high vertical wing wall bored pile foundation ...

AI Technical Summary

Problems solved by technology

At present, the energy dissipation structure usually adopts the ordinary deep excavation type energy dissipation structure. Both sides of the stilling pool adopt high wing wall structure, which is difficult to construct, and the foundation treatment of the high vertical wing wall bored pile foundation is expensive, and the water flow in the pool cannot be free. Diffusion energy dissipation often severely scours the downstream riverbed behind the pool, and even affects the stability and safety of nearby buildings
