Device and method for improving bottom scouring and silting efficiency of underground storage pond
The device comprises a water storage channel, a water retaining weir plate is arranged on the water outlet side of the water storage channel, a water outlet is formed in the bottom of the water storage channel and is opened and closed through a water outlet gate, and the water outlet side of the water storage channel directly faces the side wall of the storage tank and is of a curved surface structure so as to reduce the hydraulic loss of flushing water flow. The bottom of the storage pond is divided into a plurality of flow passing channels through the partition walls with the trapezoidal cross sections so that the flow speed of flushing water flow can be increased, and sediment at the bottom can be subjected to hydraulic flushing in the water inlet stage and the emptying stage of the storage pond. According to the invention, the regulation and storage tank can be utilized for inflow without additionally introducing an external water source, the bottom scouring and silting efficiency of the regulation and storage tank can be effectively improved to prevent the problem of silting, and the method has important engineering application value for improving the operation efficiency of an urban drainage system. Safe, energy-saving and efficient operation of the underground storage pond can be effectively guaranteed, the desilting cost is remarkably reduced, and the method is suitable for being popularized and used in design and transformation projects of the underground storage pond of an urban drainage system.
本发明公开了一种提升地下调蓄池底部冲淤效率的装置及方法，包括储水渠，储水渠出水侧采用挡水堰板，底部设有出水口且通过出水闸门进行启闭，储水渠出水侧正对调蓄池边壁采用曲面结构以减少冲洗水流的水力损失，通过采用梯形截面的隔墙将调蓄池底部分隔成多个过流通道以提高冲洗水流流速，在调蓄池进水和排空两个阶段均可对底部淤积物进行水力冲洗。本发明能利用调蓄池进流而无需额外引用外部水源，并且可有效提升调蓄池底部冲淤效率而防止其产生淤积问题，对于提高城市排水系统的运行效率具有重要的工程应用价值。本发明能够有效保障地下调蓄池的安全节能高效运行并显著降低清淤成本，适于在城市排水系统地下调蓄池的设计与改造工程中推广使用。
