The invention belongs to the technical field of building construction processes and equipment, and relates to a method for plugging water in a double-liquid grouting hole, which is mainly suitable for foundation pit engineering with a bed rock fracture water gushing risk and is used for plugging bed rock fracture water in a drill hole in a grouting manner. According to the technical scheme, the grouting technology and grouting equipment are included, double-liquid grouting can be achieved through a conventional grouting pump, double-liquid reaches the fracture position in the shortest time through the in-hole grouting device, and meanwhile the pipe blocking risk extremely prone to occurring in conventional double-liquid grouting is avoided.

    本发明属于建筑施工工艺及设备技术领域,涉及一种双液注浆孔内堵水方法,主要适用于有基岩裂隙水涌水风险的基坑工程,采用注浆方式在钻孔内对基岩裂隙水进行堵漏。本发明的技术方案包括注浆工艺和注浆设备,采用常规注浆泵也可以实现双液注浆,通过孔内注浆装置使双浆液以最短的时间到达裂隙位置,同时避免常规双液注浆极易出现的堵管风险。
