Abstract

The invention discloses an energy dissipation and erosion control dam. The energy dissipation and erosion control dam comprises a dam body. The dam body is provided with a bypass wall, a buffering impeller set, a flow blocking wall and a closure wall. The bypass wall and the buffering impeller set are arranged in a spaced mode. The bypass wall is provided with a plurality of bypass channels used for dividing water flow. The buffering impeller set comprises an impeller frame and at least one impeller arranged on the impeller frame. The flow blocking wall is provided with a plurality of flow guiding holes. The closure wall is provided with a plurality of flow guiding holes perpendicular to the flow guiding holes in the flow blocking wall. According to the energy dissipation and erosion control dam, a multi-layer combined energy dissipation and erosion control structure is adopted in the dam body, efficient energy dissipation and erosion control can be achieved, and huge damage to the dam body and a river channel due to scouring of large-flow water flow is avoided.

Description

technical field [0001] The invention relates to a dam, in particular to an energy dissipation and scour prevention dam, which belongs to the technical field of water conservancy engineering. Background technique [0002] In order to develop and utilize the hydraulic resources of the river, the water conservancy project takes engineering measures on the river course, builds hydraulic structures that control and control the water flow in accordance with relevant national regulations, and arranges them in reasonable positions to cooperate and coordinate with each other. Thus realizing an organic complex composed of hydraulic and water conservancy tasks. A dam is a representative form of water retaining and releasing structures. [0003] In recent years, with the implementation of the national western development strategy and the strategy of power transmission from west to east, many dams need to be built. These dams all have the characteristics of high water head and large flo...
