摘　　要：针对传统的排涝泵站围堰结构防渗效果差的问题,本文提出大型排涝泵站围堰结构及不停水施工技术。通过布置排涝泵站内外围堰、选择使用高压喷射防渗墙围堰、对排涝泵站的地基进行加固处理、安装进出水管,以确保泵站在使用过程中的稳定性和安全性,实现泵站在运行和维护时达到不停水的目的。实验证明,该技术的围堰结构防渗效果好,可以保证围堰结构的防渗性能,具有较高的实用性。In view of the poor anti-seepage effect of the traditional cofferdam structure of the drainage pumping station,this paper puts forward the cofferdam structure of the large-scale drainage pumping station and the construction technology of non-stop water.By arranging the inside and outside cofferdams of the drainage pumping station,choosing to use the high pressure jet cutoff wall cofferdam,strengthening the foundation of the drainage pumping station,installing the inlet and outlet water pipes,to ensure the stability and safety of the pumping station in the use process,and to achieve the purpose of uninterrupted water in the operation and maintenance of the pumping station.The experiment shows that the technology has good anti-seepage effect,can guarantee the anti-seepage performance of the cofferdam structure,and has high practicability.
