临近地铁的TRD水泥土搅拌墙防渗漏施工质量控制

Construction Quality Control of the TRD Cement Soil Mixing Wall Adjacent to the Subway

通过对杭州一个临近地铁项目的 TRD水泥土搅拌墙防渗漏施工质量采取的一系列控制措施,阐述了在已运营的地铁旁深基坑施工中如何保护地铁站房和隧道结构及基坑自身的安全,针对设计采取的TRD工法墙工艺,对每道工序进行了严格的管控,最终此项目深基坑的TRD工法墙实现了"零渗漏"的质量控制目标。

Through a subway project TRD soil-cement mixing wall seepage prevention construction quality of a series of control measures in Hangzhou,this article expounds upon the subway operation is how to protect the subway station in the deep foundation pit construction and tunnel structure and the security of foundation pit,in view of the design adopts the methods of TRD wall process,for each working procedure has carried on the strict control,finally the project of deep foundation pit TRD method realizes zero leakage wall quality control target.
