Reinforcing construction method for groove wall of underground diaphragm wall of subway station near lake complex geology
The invention provides a reinforcing construction method for a groove wall of an underground diaphragm wall of a lake-near complex geology subway station, and belongs to the technical field of underground foundation pit support structure construction of civil engineering. The lake-near complex geological subway station underground diaphragm wall groove wall reinforcing construction method comprises the following steps that a construction pile position is marked according to a control point of jet grouting pile construction measured by a total station; a mortar discharging groove is dug according to the position of the pile position mark point, and a mortar mixing system is erected; the geological drilling rig is moved to the designated pile position mark point position, and drilling is conducted on the pile position mark point position; the jet grouting pile machine is moved to the corresponding hole-forming pile position, a drill bit is aligned with the center of the hole-forming pile position, and jet grouting operation is conducted on the interior of the hole-forming pile position; cleaning back-spraying slurry at the top of the jet grouting pile, and introducing the back-spraying slurry into a sedimentation tank; the grouting pipe and other machine tools and equipment are washed with clean water; the problems that during three-shaft stirring pile construction, the grouting direction range is uncontrollable, and the underground diaphragm wall reinforcing effect is poor can be solved.
本发明提供了一种临湖复杂地质地铁车站地下连续墙槽壁加固施工方法，属于土木工程地下基坑围护结构施工技术领域，该临湖复杂地质地铁车站地下连续墙槽壁加固施工方法包括以下步骤：根据全站仪测定旋喷桩施工的控制点进行施工桩位的标记；根据桩位标记点位置挖设排浆槽，并架设灰浆拌制系统；移动地质钻机到指定桩位标记点位置，并对桩位标记点位置进行钻孔；移动旋喷桩机至相应的成孔桩位位置，使钻头对准成孔桩位中心，对成孔桩位内部进行旋喷作业；对旋喷桩柱顶部的返喷浆液进行清理，并引入沉淀池；将注浆管等机具设备用清水进行冲洗；本发明能够解决三轴搅拌桩施工时，注浆方向范围不可控，对地下连续墙加固效果差的问题。
