【摘要】：在服务区域内地下水位较高或存在雨污水管道混接的情况下,管渠系统预抽空成为雨水泵站运行的重要模式。为探讨如何发挥雨水管渠系统在小降雨事件下的蓄水功能,改善强降雨条件下雨水管渠系统的排水能力,从资料收集需求、水泵控制策略和蓄水容积计算方面论述,借以构建雨水管渠系统预抽空运行模式水力模型。通过案例定量分析了雨水泵站不同预抽空运行方案下的水泵开启次数、提升水量和运行时间。研究结果对于城市排水防涝系统结合降雨天气预报响应具有理论意义和应用价值。
[Abstract]:In the case of high groundwater level in the service area or the existence of mixed connection of rain sewer pipes. Pre-pumping of pipe and canal system has become an important mode of operation of rainwater pumping station. In order to explore how to bring into play the function of stormwater pipe system storage under small rainfall events and improve the drainage capacity of stormwater pipe canal system under heavy rainfall conditions. From the data collection requirements, pump control strategy and volume calculation of water storage discussed. In order to construct the hydraulic model of pre-pumping operation mode of rainwater pipe canal system, the pump opening times under different pre-pumping operation schemes of Rain Water pumping station were quantitatively analyzed through a case study. The results are of theoretical significance and application value for urban drainage and waterlogging prevention system combined with rainfall weather forecast response.
