Step type and spiral reverse rotation bottom sill type combined energy dissipation facility and energy dissipation method
The invention discloses a step type and spiral reverse rotation bottom sill type combined energy dissipation facility and an energy dissipation method and relates to the technical field of dam flood discharge and energy dissipation. A step type and spiral reverse rotation bottom sill type combined energy dissipation facility body comprises an overflow weir, a step structure, a spiral impeller structure and a plunge pool; the step structure comprises multiple step units and is fixed on a straight line section of the overflow weir, and each step unit comprises a step curved surface, a step vertical surface and pier structures; the spiral impeller structure comprises multiple double-spiral impeller units, and each double-spiral impeller unit comprises impellers, rotating shafts, ball bearings and fixing parts; the spiral impeller structure is fixed on a reverse curve section of the overflow weir through a base. The step structure and the spiral impeller structure are assembled on the overflow weir, the energy dissipation mode of the overflow weir is improved, higher energy dissipation and erosion control efficiency and prominent engineering practical value are realized, and the application prospect is broad.
