摘　　要：在水利工程建设中,基坑属于临时性工程,作用是提供一个施工空间,其基坑的防渗既是工程的重点也是难点,高压旋喷桩防渗围封方案,施工方便,适应性好,具有良好的防渗效果。本文以东江水源工程西枝江泵站取水口改造工程为例,该工程建基面所处的地层为中粗砂层,属强透水层,工程利用高压旋喷桩进行防渗止水,有效地解决了施工难题。In the construction of water conservancy projects,the foundation pit is a temporary project,which is used to provide a construction space.The anti-seepage of the foundation pit is not only the focus but also the diff iculty of the project.The anti-seepage enclosure scheme of high-pressure jet grouting pile has the advantages of convenient construction,good adaptability and good anti-seepage effect.Taking the water intake reconstruction project of Xizhijiang Pump Station of Dong jiang water source project as an example,the formation of the foundation surface of the project is medium coarse sand layer,which belongs to strong permeable layer.The project uses high-pressure jetting pile for anti-seepage and water stop,which effectively solves the construction problem.
