摘　　要：高压旋喷防渗墙在堤坝的地基防渗处理中被广泛应用,它能够有效有效地加强基础的防渗能力。本文以江都区高水河东堤除险加固工程为例,分析了高压旋喷防渗墙在水利工程堤防地基处理中的应用,介绍了工程概况、二重管高压旋喷桩施工流程、试桩试验概况,并根据选定的三根试桩的试验结果,拟定了最优施工方案以及施工技术参数,并提出了质量控制措施,为该地区高压旋喷防渗墙结构的设计与施工提供了参考依据,对同类工程实施具有很好的借鉴意义。The high-pressure rotary jet grouting anti-seepage wall is widely used in the foundation anti-seepage treatment of embankments,which can effectively strengthen the anti-seepage capacity of the foundation.Taking the east embankment of Gaoshui River in Jiangdu District as an example,this paper analyzes the application of highpressure rotary jet grouting anti-seepage wall in embankment foundation treatment of water conservancy projects,introduces the general situation of the project,the construction process of double pipe high-pressure rotary jet grouting piles,and the general situation of pile test.Based on the test results of three selected test piles,the optimal construction scheme and construction technical parameters are drawn up,and quality control measures are proposed,which provides a reference basis for the design and construction of high-pressure rotary jet grouting antiseepage wall structures in the region,and has good reference significance for the implementation of similar projects.
