等厚度水泥土搅拌墙技术(TRD工法)目前在国内工程实践中还刚刚起步,其在各种复杂地质条件下的成墙施工参数和成墙质量仍处于摸索阶段,必须要采用可靠的施工质量控制手段和方法来保证成墙质量。以上海虹桥商务区某工程为背景,介绍了TRD工法超深止水帷幕的施工及质量控制措施,实施效果表明:TRD工法对周边环境影响小,成墙质量好,满足了深大基坑长期大面积降压的安全与环境保护要求。
The technology of equal thickness cement soil mixing wall (TRD method) is still just beginning in domestic engineering practice. Its construction parameters and wall quality under various complicated geological conditions are still at a groping stage, so it is necessary to adopt reliable construction quality Control methods and methods to ensure the quality of the wall. Taking the project of Shanghai Hongqiao Business District as a background, the construction and quality control measures of TRD ultra-deep water curtain are introduced. The results show that: the TRD method has little impact on the surrounding environment and has good wall quality, satisfying the long-term deep foundation pit Large area buck safety and environmental protection requirements.
