【摘要】：提供了一种通过RJP工法封底加固替代抽降承压水的新思路及工艺方法。该方法通过RJP满堂加固与工程桩紧密咬合形成整体以解决承压水抗突涌稳定问题,可以减少止水帷幕的插入深度,并避免抽降承压水对环境设施的扰动。该方法在邻近地铁设施的深基坑工程中取得了良好的实践效果。
[Abstract]:In this paper, a new idea and technological method of replacing pumping confined water by RJP method is provided. This method can solve the problem of resisting surge and stability of confined water by RJP reinforcement and close bite of engineering pile. It can reduce the insertion depth of waterproof curtain and avoid the disturbance of pumping confined water to environmental facilities. The method has obtained good practical effect in the deep foundation pit engineering near subway facilities.
