摘　　要：为实现更有效的防渗防漏效果,在SMW工法桩的基础上,结合工具式双道钢管斜抛撑进行联合应用,形成一种新型的围护体系。阐述了该新型防渗防漏围护体系的工艺原理、特点以及施工工艺要点。该工艺在实践中得到了成功应用,证明其适用于城市施工场地狭窄、紧邻用地红线、周边建筑物群多、且地下水位较高等复杂环境下的深基坑围护体系施工。To achieve more effective anti-seepage and leak proof effect, a new type of support system is formed on the basis of SMW construction method piles and combined with tool type double steel pipe inclined strut. The technological principle, characteristics and key points of construction technology of the new anti-seepage and leak proof support system are described in detail. The technology has been successfully applied in practice, which proves that it is applicable to the construction of deep foundation pit support system in the complex environment of narrow urban construction site, close to the red line of land, many surrounding buildings, and high groundwater level.
