Grouting leaking stoppage construction method for underground open cut structure
The invention discloses a grouting leaking stoppage construction method for an underground open cut structure, which realizes all-directional leaking stoppage and can effectively solve the problem of leakage. The grouting leaking stoppage construction method comprises the following construction processes of construction preparation, wherein equipment is arranged on the ground of a top plate; hole site design and lofting are carried out, and grouting holes are formed in a bottom plate, a side wall, an open cut structure and an entrance and exit of the main body structure; scanning and positioning are conducted, specifically, the hole sites subjected to lofting are scanned, and if the grouting holes are distributed in the steel bars, the positions of the grouting holes are adjusted; drilling and mounting a grouting pipe, drilling a grouting hole and an observation hole, mounting the grouting pipe in the grouting hole, and arranging a ball valve switch; grouting is conducted according to the sequence of the water collecting well, the entrance of the entrance, the bottom plate, the side wall of the bottommost layer and the side wall of the upper layer, and operation is cyclically conducted to the negative layer; secondary grouting is conducted, and if water leakage exists in the reinforced concrete structure, secondary grouting is conducted for blocking; and the structure is repaired, after the cement paste is solidified, the grouting pipe is pulled out, and the grouting holes are filled with the cement paste.
本申请公开了一种地下明挖结构的注浆堵漏施工方法，实现全方位堵漏，能够有效解决渗漏问题。注浆堵漏施工方法包括如下施工流程：施工准备，在顶板地面布置设备；孔位设计及放样，在主体结构底板、侧墙、明挖结构及出入口的洞口出布置注浆孔；扫描定位，对已做好放样的孔位进行扫描，若注浆孔布设在钢筋上，则调整注浆孔的位置；钻孔及安装注浆管，钻设注浆孔和观察孔，在注浆孔安装注浆管并设置球阀开关；注浆，注浆顺序为：集水井、出入口的洞口、底板、最底层侧墙、往上一层侧墙，并循环操作至负一层；二次补浆，若钢筋混凝土结构存在渗漏水，则进行第二次注浆进行封堵；结构修复，水泥浆凝固后拔除注浆管并用水泥浆灌满注浆孔。
