The invention relates to the technical field of tunnel waterproofing, in particular to a subway tunnel grouting, leaking stoppage and reinforcement construction method and system.The tunnel terrain is positioned, the punching position is determined, holes are distributed based on the punching position, cement, water glass, latex, a micro-expanding agent and concrete are prepared according to a preset proportion, and grouting liquid is obtained; according to the construction method, the watertightness and the bearing capacity of the foundation are improved, it is guaranteed that the tunnel wall is not impacted by water pressure, after construction is completed, no water seeps out of the tunnel wall after observation is conducted for 36-72 hours, the water seepage problem can be solved from the source, the construction period is shortened, and the construction efficiency is improved. The problem of water seepage is solved, meanwhile, the inner wall of the tunnel is reinforced, the non-seepage and non-leakage effect can be completely achieved, and therefore the problem that an existing tunnel wall injection grouting method is low in practicability is solved.
本发明涉及隧道防水技术领域，具体涉及一种地铁隧道灌浆堵漏加固施工的方法及系统，对隧道地形进行定位，确定打孔位置，基于打孔位置进行布孔，按预设比例配置水泥、水玻璃、乳胶、微膨胀剂和混泥土，得到灌浆液，使用灌浆机将灌浆液注入灌浆孔内，待灌浆液凝固完成堵漏加固施工，本发明提高地基的不透水性和承载力，确保隧道墙体不受水压的冲击，施工完成后，经过36小时至72小时观察隧道墙体无水渗出，能够从根源上解决渗水问题，在解决渗水问题的同时对隧道内壁起到加固作用，能够完全达到不渗不漏的效果，从而解决了现有的隧道墙体打针注浆方法实用性较低的问题。
