TRD止水帷幕成墙质量控制

TRD WATER CURTAIN WALL FORMING QUALITY CONTROL

随着当今建设项目越来越复杂,对深基坑围护、地下水控制采用的施工工艺要求日益提高。TRD止水帷幕有着止水效果好、垂直度高、施工深度大等优点,但此工艺在北方地区可以借鉴的实例不多。本项目通过TRD试验段施工,进一步进行试验确定TRD试验段的成墙质量,以保证TRD止水帷幕正式施工。

With more and more complex construction projects nowadays,the construction technology requirements for deep foundation pit retaining and groundwater control are increasing day by day.TRD water stop curtain has the advantages of good water stop effect,high verticality and large construction depth,but there are few examples of this process in northern China.In this project,through the construction of TRD test section,further tests are carried out to determine the wall forming quality of TRD test section,so as to ensure the formal construction of TRD water stop curtain.
