Discontinuous convex type step energy dissipater

The utility model discloses a discontinuous convex type step energy dissipater, which comprises a plurality of steps of convex type ladder step-down floors arranged on a spillway chute section and distributed on the spillway chute section discontinuously. The discontinuous convex type step energy dissipater can be applied to the hydraulic engineering, particularly suitable to terrain with a gentle slope and has the advantages of being simple in shape, convenient in construction, high in energy dissipation ratio, strong in practical applicability, wide in application, good in safety, and capable of shortening construction period and saving project investment and the like. In addition, the discontinuous convex type step energy dissipater can effectively increase aerial drainage friction drag of the chute surface, turbulent fluctuation aeration and roll swirl energy dissipation, reduces flow speed and eliminates aerial drainage energy of the chute section, thereby having good energy dissipation and erosion control effects.
