摘　　要：在泥质粉砂岩地层地下连续墙施工中,因为泥质软岩有一定塑性,又在一定深度中风化岩层具有较硬的强度,在连续墙施工机械越来越丰富的今天,研究如何在冲孔桩、旋挖钻、液压抓斗和双轮铣槽机之间选择和配置并采用适当的成槽工艺,以提高连续墙的成槽效率,是一个值得研究的课题。During the construction of underground diaphragm walls in argillaceous siltstone strata,due to certain plasticity of the argillaceous soft rock and relatively hard strength of the weathered rock strata at a certain depth,with the increasingly abundant construction machinery for diaphragm walls at present,it is necessary to study how to select and configure punching piles,rotary drilling machine,hydraulic grab buckets and double-wheel slotters and the use of appropriate groove forming technology to improve the groove formation efficiency of diaphragm wall,which is a research topic of concern.
