Stepped grading spillway with energy dissipation effect
The invention discloses a stepped graded spillway with an energy dissipation effect, and belongs to the technical field of water conservancy and hydropower building engineering. The spillway comprises a first-stage stilling pool, a first-stage chute, a second-stage stilling pool, a third-stage stilling pool, a second-stage chute, a fourth-stage stilling pool and an apron which are sequentially arranged from upstream to downstream, the upstream side of the first-stage stilling pool is connected with a flood discharge tunnel, and the downstream side of the apron is smoothly connected with an original river channel. The spillway is arranged at an outlet of the spillway tunnel, and spillway water flows through the multi-stage stilling pool and the multi-stage chute to fully dissipate energy and then is discharged into an original river channel, so that scouring to the original river channel is relieved, and the safety of downstream buildings is guaranteed; meanwhile, due to the fact that the first-stage stilling pool, the first-stage chute, the second-stage stilling pool, the third-stage stilling pool, the second-stage chute and the fourth-stage stilling pool are each of a closed structure in the transverse direction, flood discharge atomization can be prevented from being caused in the energy dissipation process.
本发明公开了一种具有消能效果的阶梯形分级溢洪道，属于水利水电建筑工程技术领域。该溢洪道包括从上游至下游依次设置的一级消力池、一级陡槽、二级消力池、三级消力池、二级陡槽、四级消力池和海漫，所述一级消力池的上游侧与泄洪洞相接，所述海漫的下游侧与原河道平顺相接。溢洪道设置于泄洪洞的出口，泄洪水流经多级消力池和多级陡槽充分消能后排入原河道，以减轻对原河道的冲刷，并保证下游建筑物安全；同时，由于一级消力池、一级陡槽、二级消力池、三级消力池、二级陡槽、四级消力池的横向为封闭结构，能够防止在消能过程中引起泄洪雾化。
