基于大直径高压旋喷桩施工技术的深基坑防渗方法研究——以某地块工程项目为例

Study on Anti-seepage Method of Deep Foundation Pit based on Large-diameter Highpressure Jet Grouting Pile Construction Technology——Take a block project as an example

此次研究以杭政储出[2005]70号地块工程项目为例,开展实例应用分析。为避免深基坑在施工中渗漏影响工程进度问题,基于大直径高压旋喷桩施工技术的应用,设计一种针对深基坑的防渗方法,以此提高基坑工程质量。

In order to avoid the leakage in the construction of deep foundation pit that will affect the project progress, this study takes the Hangzheng Reservoir [2005]No. 70 block engineering project as an example to carry out a case application analysis. Based on the application of large-diameter high-pressure jet grouting pile construction technology, a seepage control method for deep foundation pit is designed, which can improve the quality of foundation pit engineering.
