Hedging type flood discharging and energy dissipation structure and method
The invention discloses a hedging type flood discharging and energy dissipation structure and method. The hedging type flood discharging and energy dissipation structure comprises a stilling basin, atunnel is arranged on the periphery of the stilling basin, one end of the tunnel communicates with a reservoir, and the other end of the tunnel correspondingly communicates with two opposite inner side walls of the stilling basin through branched pipes. By adopting the technical scheme of the hedging type flood discharging and energy dissipation structure, during the flood discharging of the reservoir, a valve A and a valve B are opened, so that water flow in the reservoir flows into the stilling basin sequentially through the tunnel, the branched pipes and the two opposite inner side walls ofthe stilling basin, the water flow mutually hedges and collides a flood discharging water tongue in the stilling basin, energy of the flood discharging water tongue and own jet flow is dissipated inthe collision process, and then the water flow falls to the bottom of the stilling basin. A water cushion is arranged at the bottom of the stilling basin to eliminate the rest energy in the water flow, so that the energy in the water flow is sufficiently dissipated, the washing of an underwater bed, a bank slope and other buildings is reduced, the energy dissipation efficiency is improved, the safety of the downstream buildings is ensured, and the washing action force of the water cushion is reduced.
本发明公开了一种对冲式泄洪消能结构及方法，包括消力池，消力池外围布置有隧洞，隧洞的一端与水库连通，隧洞的另一端分别通过支管连通于消力池彼此相对的两个内侧壁。采用本发明的技术方案，在水库泄洪时，通过开启阀门A和阀门B，使水库中的水流依次通过隧洞、支管、消力池彼此相对的两个内侧壁流入消力池以内，使水流在消力池内与泄洪水舌形成相互对冲碰撞，在碰撞过程中消散泄洪水舌及自身射流中的能量，再跌落至消力池底部，通过消力池底部设置的水垫消除水流中剩余能量，使水流中的能量能够充分消散，减轻了对下游河床、岸坡以及其他建筑物的冲刷，提升了消能效率，保障了下游建筑物的安全，减少了对水垫的冲刷作用力。
