Rectangular steel sleeve vertical pipe sinking combined horizontal drilling coring obstacle removing construction method
The invention relates to the technical field of building construction, in particular to a rectangular steel sleeve vertical pipe sinking combined horizontal drilling coring obstacle removing construction method. The method specifically comprises the following steps of field hardening, drilling and soil taking, horizontal drilling equipment preparation, horizontal drilling operation, completion of pile (wall) hole site breaking, taking out of construction waste generated in the breaking process, upward pulling of a pipe out of a rectangular steel sleeve, backfilling of cemented soil, drilling operation of a next hole site and completion of breaking of the next hole site. Building rubbish generated in the breaking process is taken out, the steps are repeated till breaking of all the hole sites is completed, all the building rubbish is taken out, and the backfill cement soil hole sites are subjected to grouting reinforcement; according to the method, vertical pipe sinking of the rectangular steel sleeve and horizontal drilling coring are combined, meanwhile, special tool rectangular steel sleeve pipe sinking (pulling) equipment is adopted, assembly type transportation and installation are achieved, and efficient and accurate obstacle clearing of the underground of an existing subway is achieved.
本发明涉及建筑施工技术领域，具体涉及一种矩形钢套管垂直沉管结合水平钻取芯清障工法；本发明具体包括以下步骤：场地硬化，钻孔取土，水平钻进设备准备，水平钻孔作业，完成桩（墙）孔位的破除，取出破除过程中产生的建筑垃圾，管向上拔出矩形钢套管，同时回填水泥土，下一孔位进行钻孔作业，完成下一个孔位的破除，取出破除过程中产生的建筑垃圾，重复直至完成所有孔位的破除，并且取出所有的建筑垃圾，对回填水泥土孔位注浆加固；本发明通过矩形钢套管垂直沉管与水平钻取芯相结合，同时采用专有工装矩形钢套管沉（拔）管设备，实现了装配式运输安装，实现了现有地铁地下高效、精准清障。
