摘要
结合工程实例论述了帷幕注浆的设计要点、施工工艺以及判定止水效果的原位测试方法。工程实践表明:采用帷幕注浆对不同地层均能取得强度增加、渗透系数减小的工程效果,保证了桩基的顺利施工。
The key points, construction technology and test method of water proof in situ were discussed in this paper. The result of a practical engineering demonstrated that the strengths of all kinds of strata soil treated by this method had a great increment and the curtain grouting technology could prevent water very well when holes were dug.
