Energy dissipation device and energy dissipation method for siphon pressure flow rainwater drainage pipeline outlet
The invention provides an energy dissipation device and an energy dissipation method for a siphon pressure flow rainwater drainage pipeline outlet. The energy dissipation device comprises an upstream rainwater pipeline, a downstream rainwater pipeline and an anti-scouring cushion layer, wherein the upstream rainwater pipeline is arranged on the upstream side of the energy dissipation device and is arranged to receive transmitted roof rainwater; the downstream rainwater pipeline is arranged on the downstream side of the energy dissipation device and is arranged to discharge rainwater in the energy dissipation device; the anti-scouring cushion layer is arranged at the bottom of the energy dissipation device and is used for buffering impact of the roof rainwater entering the energy dissipation device through the upstream rainwater pipeline. The energy dissipation device and the energy dissipation method have the beneficial effects that energy carried by water flow at the siphon pressure flow rainwater drainage pipeline outlet is safely dissipated in a relatively small space and a relatively short distance, so that upstream and downstream water flow is properly joined, and overflow is avoided; meanwhile, destructive effects such as cavitation erosion, pulsation, vibration, abrasion and scouring caused by the water flow are weakened, and safe and stable work of a drainage inspection well and a drainage pipeline is guaranteed.
本发明提供一种虹吸压力流雨水排水管道出口的消能装置及消能方法，包括：上游雨水管道、下游雨水管道和防冲刷垫层，所述上游雨水管道设置于消能装置的上游侧，被设置于接收经传输过来的屋面雨水；所述下游雨水管道设置于所述消能装置的下游侧，被设置于排出所述消能装置中的雨水；所述防冲刷垫层设置于所述消能装置的底部，用于缓冲经所述上游雨水管道进入所述消能装置的所述屋面雨水的冲击。本发明的有益效果是在较小空间和较短距离内，将虹吸压力流雨水排水管道出口水流挟带的能量安全的泄散，使上下游水流获得妥善衔接，避免溢流，同时，减弱水流引起的空蚀、脉动、振动、磨损以及冲刷等破坏作用，保证排水检查井和排水管道的安全稳定工作。
