Gas lift reverse circulation cutter suction type underground diaphragm wall construction method and underground diaphragm wall
The invention relates to a gas lift reverse circulation cutter suction type underground diaphragm wall construction method and an underground diaphragm wall; a grooving drilling machine with a submersible drilling machine is utilized, grooves are formed in a construction path of the underground diaphragm wall in a gas lift reverse circulation cutter suction mode, and a cable box is constructed and manufactured in advance so as to protect the section of a pipeline in the construction path; the guide wall on the side edge of the cable box is fixed together with the working track through the embedded part, the pipeline section is in suspended connection through the chain block for protecting the truss to be vertically placed, the pipeline section cannot be affected even if force is accidentally applied to the guide wall during movement and operation of the grooving drilling machine on the working track, and the pipeline cannot droop and deform in the grooving process, so that damage to the pipeline section in the underground diaphragm wall in the construction process is reduced to the minimum, the underground diaphragm wall without pipeline migration is finally completed, and application of the gas lift reverse circulation cutter suction type construction method in underground diaphragm wall construction is achieved.
本发明涉及一种气举反循环绞吸式地下连续墙施工工法与地下连续墙，利用具有潜水钻机的成槽钻机并以气举反循环绞吸方式在地下连续墙施工路径开设成槽，此前先预先施工制作出电缆箱，以保护管道在施工路径中的区段，电缆箱侧边的导墙经由预埋件与工作轨道固定一起，管道区段另以保护桁架垂放的倒链悬吊连接，成槽钻机在工作轨道上的移动与作业即使意外施力于导墙也不会影响管道区段，在成槽过程中管道也不会下垂变形，施工过程对在地下连续墙内管道区段的破坏损害降到最低，最终完成不需要迁移管道的地下连续墙，实现了气举反循环绞吸式工法在地下连续墙施工中的应用。
