摘　　要：总结液压抓斗纯抓法造槽建造嵌岩混凝土防渗墙施工技术在多个混凝土防渗墙工程造槽施工中的应用情况和控制松散地层槽孔壁坍塌的造槽施工经验,形成了嵌岩混凝土防渗墙液压抓斗纯抓法造槽施工技术;该项造槽施工技术创新了松散填筑土层、砂质地层、砂卵石地层等槽孔壁易坍塌的松散地层造槽时有效控制槽孔壁坍塌的操作工艺技术,经工程实践验证,松散地层造槽时的槽孔壁坍塌得到了有效的控制,有较好的推广应用前景。This paper summarizes the application of the construction technology of rock socket concrete cut-off wall with hydraulic grab and pure grab method in the construction of many concrete cut-off wall projects and the construction experience of controlling the collapse of slot wall in loose stratum,forming the construction technology for rock socket concrete cut-off wall with hydraulic grab and pure grab method,This slotting construction technology innovates the operation technology to effectively control the slotting hole wall collapse when slotting in loose stratum such as loose fill soil layer,sandy stratum and sandy cobble stratum,etc and the collapse of channel wall in slotting of loose formation can be effectively controlled in the engjneering practice,whose application prospect is promising.
