Energy dissipation structure giving consideration to water level change and flow change and construction method
The invention discloses an energy dissipation structure giving consideration to water level change and flow change and a construction method, and belongs to the technical field of flood discharge and energy dissipation and hydraulic building construction. The flood drainage channel section, the energy dissipation step section, the smooth connection section and the flip flow energy dissipation reverse arc section are sequentially arranged between the two side walls in the water flow flowing direction; the flip flow energy dissipation base is anchored below the flip flow energy dissipation reverse arc section; the crest elevation of the flip bucket energy dissipation base is larger than the low-level water level of the water storage reservoir in the flood season and smaller than the high-level water level of the water storage reservoir in the flood season, and the downstream end elevation of the energy dissipation step section is larger than the low-level water level of the water storage reservoir in the non-flood season and smaller than the high-level water level of the water storage reservoir in the non-flood season. Through sequential energy dissipation of water flow through the energy dissipation step section and the flip flow energy dissipation reverse arc section, mutual cooperation of multiple energy dissipation modes is achieved, and the energy dissipation effect is improved.
本发明公开了泄洪消能与水工建筑施工技术领域的一种兼顾水位变化和流量变化的消能结构及施工方法，包括边墙；沿水流流动方向顺序设置在两个边墙之间的排洪渠道段、消能台阶段、平顺连接段、和挑流消能反弧段挑流消能鼻坎；锚固在挑流消能反弧段下方的挑流消能基座；挑流消能基座的顶高程大于蓄水库的汛期低位水位并小于蓄水库的汛期高位水位，消能台阶段的下游端高程大于蓄水库的非汛期低位水位并小于蓄水库的非汛期高位水位。本发明通过消能台阶段和挑流消能反弧段对水流的先后消能，实现了多种消能方式的相互配合，提高了消能效果。
