超深地下连续墙施工中几个问题的探讨

Discussion of Several Problems in Ultra-deep Underground Continuous Wall Construction

摘要:

结合武汉某地下连续墙工程，探讨了超深嵌岩地下连续墙施工过程中出现的因三轴搅拌桩施工造成成槽困难的问题，以及超深地下连续墙接头管安装和起拔问题，并提出了相应的解决措施。实践证明，这些措施是有效的，可以为武汉地区的类似工程提供参考。

Abstract:

Based on an underground continuous wall construction project in Wuhan, this paper discusses difficulties caused by three-axis mixing pile construction in the ultra-deep rock-socketed underground continuous wall and in the joint pipe installation and drawing with corresponding solution measures. The practice proves that these measures are effective and can be reference for similar engineering in wuhan.
