针对上海肇嘉浜雨水污水合建式泵站原设计进水系统排沙情况进行模型试验分析,根据模型试验提出了排沙廊道改造方案。经试验,排沙廊道方案可以有效解决进水系统中的推移质泥沙淤积问题。该方案对类似泵站进水系统的排沙问题有一定的借鉴作用。
According to the model test and analysis of the sediment discharge of the original design intake system of Zhaojiabang rainwater and sewage combined construction pump station in Shanghai, a plan of desertification corridor reconstruction is proposed according to the model test. After testing, sediment removal corridor program can effectively solve the problem of pumped sediment deposition in the water system. This scheme has certain reference function for the sediment discharge problem of similar pumping station water system.
