地连墙穿越微承压水粉砂层预降水防坍成槽

摘要

Taking the No.2 track diaphragm wall project in Ningbo as the example,the study depicts the construction methods for the diaphragm wall across micro-artesian silt layer for beforehand rainfalls anti-dumping and trenching formation,analyzes its construction technique,and cancels the three-shaft stirring pile to consolidate the soil,so as to reach the energy-saving and emission reduction and reduce the cost to some extent.%以宁波轨道交通2号线地下连续墙工程施工为例,对地下连续墙穿越微承压水粉砂层防坍成槽施工方法进行描述,针对地下连续墙穿越微承压水粉砂层预降水防坍成槽施工技术进行分析,取消三轴搅拌桩加固土体,从而在一定程度上达到节能减排、降低造价的目的。
