Grouting plugging method suitable for large karst cave under high-flow-speed flowing water condition
The invention relates to a grouting plugging method suitable for a large karst cave under a high-flow-rate flowing water condition, which comprises the following steps: 1, forming a grouting hole, namely drilling by using drilling equipment to form the grouting hole and a mounting hole. 2, mounting a cloth bag device, arranging the lower end of the cloth bag device in the mounting hole, and arranging the upper end of the cloth bag device in the grouting hole; 3, conducting grouting and pre-plugging, and injecting grout into the geotechnical cloth bag; 4, conducting feeding hole forming, specifically, conducting drilling on the upstream of the high-flow-speed flowing water through drilling equipment, and forming a feeding hole; 5, putting soft and hard aggregates, and putting the soft and hard aggregates into the karst cave through a feeding pipe; 6, grouting and plugging a feeding hole, and injecting cement-water glass double slurry into the feeding hole; 7, conducting high-pressure grouting hole forming, specifically, drilling the solidified grout in the geotechnical cloth bag through to form the high-pressure grouting hole; and 8, conducting high-pressure grouting, specifically, conducting high-pressure grouting in the high-pressure grouting holes. The method has the advantages of reasonable step design, good construction, good plugging effect, good plugging reliability and the like.
本发明涉及适用于大溶洞高流速动水条件下的注浆封堵方法，包括以下步骤：步骤一：注浆孔成孔，用钻孔设备钻孔，形成注浆孔和安装孔；步骤二，安装布袋装置，将布袋装置下端设置在安装孔内，上端设置在注浆孔内；步骤三，注浆预封堵，将浆液注入土工布袋内；步骤四，投料孔成孔，在高流速动水上游用钻孔设备钻孔，形成投料孔；步骤五，投放软硬骨料，将软硬骨料通过投料管向溶洞内投放；步骤六，投料孔注浆封堵，将水泥‑水玻璃双浆液注入投料孔；步骤七，高压注浆孔成孔，将土工布袋内凝固的浆液钻穿形成高压注浆孔；步骤八，高压注浆，向高压注浆孔内高压注浆。具有步骤设计合理、好施工、封堵效果好、封堵可靠性好等优点。
