[0053] Example 1:
[0054] A high-pressure grouting method for plugging the settlement joints of buildings includes the following steps:
[0055] 1) First, clean the surface of the settlement joint to be repaired, and determine the position and length of the settlement joint;
[0056] 2) According to the width and depth of the settlement joint, first insert the polystyrene foam board and the water-swellable water-stop strip into the settlement joint, and then insert the polystyrene particles into the remaining gap after the first insertion in the settlement joint;
[0057] 3) Use thin wood, hard rubber or plastic strips to seal the leakage opening of the settlement joint. The width of the thin wood, hard rubber or plastic strip is 6cm wider than the width of the settlement joint. Thin wood boards, hard rubber strips or plastic strips are sealed and glued on the wall on both sides of the settlement joint;
[0058] 4) Drill a grouting hole on the wall near the settlement joint, and embed...
