超深基坑止水帷幕TRD与防渗墙工法对比分析

Comparison Analysis on Water-stop Curtain Methods of TRD and Cut-off Wall for Ultra Deep Foundation Pit

摘要:

重点从成本、工效、抗渗质量、环保、耗材等方面对TRD工法墙和成槽机施工的防渗墙做了详细的对比分析论证，认为在相同条件下防渗墙整体优于TRD工法墙，是一种先进可靠的防渗工艺，值得在超深基坑侧壁及坑底止水方面大力推广使用。

Abstract:

The comparison analysis is made in detail on the wall by TRD method and cut-off wall by slot machine in construction cost, work efficiency, anti-seepage quality, environmental protection and consumptive material. The results show that cut-off wall is better than TRD method wall under the same conditions, which is an advanced and feasible waterproof construction technology and deserves popularization and application in the ultra deep foundation pit waterproof.
