受限空间内地道泵站集约型升级改造设计

Design of Intensive Upgrading and Renovation of Underground Pumping Stations in Confined Spaces

地道泵站作为城市基础设施生命线安全工程之一,多数城市现有地道泵站标准偏低,无法满足排水排涝要求,存在风险隐患。以莲池南大街地道泵站为例,分析地道泵站的特点,针对空间受限的情况下,介绍泵站规模、工艺设计及运行模式等改造要点。泵站集约化改造后,排水能力明显提升,增设的初雨调蓄池能有效应对地表径流污染。

As one of the safety engineering of the lifeline of urban infrastructure,the existing tunnel pump stations in most cities have low standards,which cannot meet the requirements of drainage and waterlogging,and there are potential risks.This article took Lianchi South Street underground pump station as an example,analyzed the characteristics of the underground pump station and introduced the key points of transformation such as pump station scale,process design,and operation mode in the case of limited space.After the intensive transformation of the pump station,the drainage capacity had been significantly improved,and the addition of the initial rainwater storage tank could effectively cope with surface runoff pollution.
