Multi-stage reciprocating flow weir type energy dissipation vertical shaft
The invention discloses a multistage reciprocating flow weir type energy dissipation vertical shaft which comprises an outer shaft, an inner shaft, a first-layer partition plate, a first-layer weir plate, a plurality of partition plates and a plurality of weir plates, a water inlet communicated with a shallow drainage system is formed in the upper portion of the outer shaft, and a water outlet communicated with a deep drainage system is formed in the lower portion of the outer shaft. Incoming flow of a shallow drainage system enters the drop chamber through the water inlet, falls into the lower water tank formed by the partition plate and the weir plate in the drop chamber through the upper water tank formed by the first-layer partition plate and the first-layer weir plate and then falls into the lower water tank formed by the partition plate and the weir plate from the upper-stage lower water tank, and stable outflow is ensured by arranging the weir plate, creating a water cushion layer and reducing the flowing speed of the discharged incoming flow; and finally, incoming flow is fed into a deep drainage system, kinetic energy and potential energy of the incoming flow are eliminated as much as possible in the process, gas entrained by the incoming flow is exhausted during falling, and the problems that due to existing vertical shaft design, poor hydraulic conditions are caused, and structural damage of the vertical shaft and the deep drainage system is caused by insufficient energy dissipation are solved.
本发明公开了一种多级往复流堰式消能竖井，其包括外井筒、内井筒、首层隔板、首层堰板、多个隔板和多个堰板，外井筒的上部设有与浅层排水系统相连通的进水口，外井筒的下部设有与深层排水系统相连通的出水口。浅层排水系统的来流经过进水口进入跌水室，在跌水室内由首层隔板和首层堰板形成的上水槽跌落至隔板和堰板形成的下水槽内，再由上一级下水槽跌落至下一级下水槽，通过设置堰板，创造水垫层并降低下泄来流流速，确保出流稳定，最终将来流送入深层排水系统中，在此过程中尽量消除来流的动能和势能，并在跌落时排出来流夹带的气体，解决现有竖井设计导致不良水力条件，消能不充分造成竖井和深层排水系统的结构破坏的问题。
