富水砂层中地下连续墙施工技术

On construction technique for underground continuous wall at rich water sand layer

以某城际快速轨道交通车站工程为例,结合该项目场地地质条件,介绍了富水砂层中地下连续墙施工技术,着重阐述了围护结构选型时应考虑因素,保障成槽顺利实施措施及连续墙接头选型三方面内容,以指导实践。

Taking the station project of some interurban express rail communication as the example, the study introduces the construction tech- nique of underground continuous wall at rich water sand layer by combining with the geological condition of the construction site, and illustrates the factors should be considered in the enclosure structure type selection process, the implementation of measures to ensure the groove formation and the selection for the joint of the underground continuous wall, so as to direct the practice.
