Novel spillway energy dissipation system with arc-shaped cylindrical side wall
The invention discloses a novel spillway energy dissipation system with an arc-shaped cylindrical side wall. The novel spillway energy dissipation system slightly scours downstream riverways and bank slopes, has a low cost, a simple and compact structure and high flood discharge capacity, is free from flood atomization, shortens the length of a downstream stilling pool, has a long service life, is resistant to impact, is high in durability, and organically combines energy dissipation by trajectory jet, ladder energy dissipation, arc-shaped cylindrical side wall energy dissipation, energy dissipation by surface flow and energy dissipation by underflow into a whole. The novel spillway energy dissipation system consists of a transition section, a step, an arc-shaped cylindrical side wall, a flip bucket, sawteeth and an energy dissipation ridge. A water flow reaches the step and the arc-shaped cylindrical side wall section through the transition section, the flip bucket is connected to the tail end of the step to pick the water flow to the downstream sawtooth section, the energy dissipation ridge is connected behind the sawtooth section, and the water flow finally enters the riverway through the energy dissipation ridge.
本发明公开了一种优化水流条件，对下游河道、岸坡冲刷小，造价低廉，结构简单紧凑，泄洪能力强，洪水没有雾化，减短了下游消力池长度，使用寿命长，抗冲击、耐用性高的，集挑流、阶梯、弧形圆柱边墙、面流、底流消能有机地结合在一起地新型弧形圆柱边墙溢洪道消能系统。它由过渡段、阶梯及弧形圆柱边墙、挑坎、锯齿、消能坎组成；水流经过过渡段到达阶梯和弧形圆柱边墙段，在阶梯末端接挑坎，将水流挑至下游锯齿段，锯齿段后接消能坎，水流最后通过消能坎进入河道。
