基坑井点式排水在汪祠排涝站施工中的应用

Application of Well-point Foundation Pit Drainage in the Wangci Drainage Pump Station Construction

汪祠排涝泵站改造工程施工导流与基坑排水是整个工程施工的重点与难点,施工导流对施工过程中降雨、圩内排水发挥有重要影响,同时,基坑排水对基坑开挖、水下工程的施工起到关键作用。主要介绍宣州区汪祠排涝站技改工程井点式基坑排水的施工方法与经验,为类似中小型排涝站工程施工中引以借鉴。

Construction diversion and foundation pit drainage is the most difficult and important of the entire technical innovation project for Wangci drainage pump station, construction diversion plays an important impact on the drainage of rainfall in the constructing process, and foundation pit drainage has an critical effect on foundation pit excavation and underwater engineering construction simultaneously. The paper describes the methods and experience of well-point foundation pit drainage, which can be borrowed in the similar technical innovation project for drainage pump station.
