The invention relates to an emergency treatment method for grout bursting in a connected cavity at the bottom of a prefabricated concrete shear wall. The grout bursting situation is divided into two states according to the position and the degree of damage of the sealing strip, wherein: the inner side of the prefabricated outer wall or the prefabricated On any side of the inner wall, when the sealing strip is completely or partially disengaged, follow the steps below: S1. Reset the disengaged connecting cavity sealing strip to achieve effective connection with the part that has not been disengaged; S2. Select at least one point on the sealing strip, move back to set the distance and fix a point on the floor, nail a steel drill bit vertically to the floor at the fixed point, insert a wooden strip between the steel drill bit and the sealing strip, and the position of the wooden strip passes through the steel drill bit Provide counter force, tighten the sealing strip, and apply an appropriate amount of quick plugging material on both ends of the reset and tightened sealing strip; S3, implement secondary grouting. The invention can handle emergency and quickly restore grouting, and improve the work efficiency and emergency response ability of the construction site.
