顶进工作坑高压旋喷桩止水帷幕设计

On waterproof curtain design of high-pressure jet grouting pile at thrust pits

结合工程实例,介绍了高压旋喷桩止水帷幕在框架桥顶进工作坑中的应用,从参数设置及渗透稳定性等技术要求出发,提出止水帷幕的技术措施,并总结了施工中应注意的具体事项,以确保基坑的整体稳定。

Combining with the engineering examples,the paper introduces the application of the high-pressure jet grouting pile at thrust pits,points out the waterproof curtain＇s technical measures from the parameter allocation and permeability stability,and sums up some precautions in the construction,so as to ensure the integrated stability of the foundation pit.
