摘要
结合某塔式起重机基坑止水+封底帷幕工程,介绍DJP工法止水+封底帷幕在高水位、高渗透性砂层中的成功应用,并对其工艺进行了机理分析。通过分析和本工程基坑开挖效果,证明DJP工法在类似地层条件下施工止水及封底帷幕的可靠性。
This paper introduces the successful application of DJP method waterproof wall and bottomsealing curtain in the sand layer of high water level and high permeability,and it also analyzes the mechanism through tower crane foundation project.Through the analysis of the excavation effect of foundation excavation of this project,the reliability of the DJP method in the construction of water stop and back curtain under similar stratigraphic condition is proved.
