含水砂层中地下连续墙的施工技术

Underground continual wall construction technology in water-bearing sand

在含水砂层中确保围护地下连续墙既挡土又止水防渗是较为复杂的施工技术。结合广州地铁三号线赤岗塔站工程实践,详细叙述了含水砂层地下连续墙的施工技术,并提出了具体的防备措施。

To make sure underground continual walls in the water-bearing sand prevent both the soil and water seepage is a complex construction technology.Taking the Guangzhou metro three lines Chigang Pagoda station project practice as an example,we will discuss underground continual wall construction technology in the water-bearing sand, and proposed the concrete protection measures.
