Core-pulling hole plugging method
The invention discloses a core-pulling hole plugging method. The method comprises the following steps that S1, a plugging groove is formed in the periphery of an opening of a core-pulling hole; S2, a plugging sleeve is inserted into the core pulling hole, the upper portion of the plugging sleeve protrudes out of the exterior of the plugging groove, and a gate valve is installed on the upper portion of the plugging sleeve; S3, a water glass solution and a cement paste solution are injected into a gap between the plugging sleeve and the core-pulling hole, and after the water glass solution and the cement paste solution are glued into silica gel and calcium silicate gel, plugging agents are injected into the plugging groove to plug the surfaces of the silica gel and the calcium silicate gel; S4, a grouting pipe is inserted into the plugging sleeve, the water glass solution, the cement paste solution and an expanding agent are injected along the grouting pipe, and a gate valve is closed after the grouting pipe is filled; and S5, after preset time, the gate valve is opened and the core-pulling hole is observed, and if the core-pulling hole does not have the phenomenon of water overflowing or water gushing, the parts, protruding out of the plugging groove, of the plugging sleeve and the grouting pipe are cut off, and the plugging groove is filled with the plugging agents.
本发明公开了一种抽芯孔封堵方法，包括以下步骤：S1、沿抽芯孔的开口外周开设有封堵凹槽；S2、在抽芯孔中插入封堵套管，并使封闭套管的上部突出于封堵凹槽的外部，在封堵套管的上部安装闸阀；S3、沿封堵套管与抽芯孔之间的间隙注入水玻璃溶液和水泥浆溶液，待水玻璃溶液和水泥浆溶液胶粘成硅胶和硅酸钙凝胶后，向封堵凹槽内注入堵漏灵以封堵硅胶和硅酸钙凝胶的表面；S4、在封堵套管中插入注浆管，沿注浆管注入水玻璃溶液、水泥浆溶液及膨胀剂，待注浆管注满后关闭闸阀；S5、待预定时间后打开闸阀并观察抽芯孔；若抽芯孔不出现溢水或涌水现象，则截断封堵套管及注浆管突出于封堵凹槽的部分，并采用堵漏灵填充封堵凹槽。
