step two: installing the buried water stop (7), closely attaching the polyphenyl plates (4) on the upper side and the lower side of the buried water stop (7) to a ring in the middle of the buried water stop (7) to form certain extrusion, and then bonding the polyphenyl plates (4) on the upper side and the lower side with a steel plate (8) welded on the stirrup by using a building adhesive to firmly fix the buried water stop (7);
step three: after the reinforcement of the other side of the expansion joint of the bottom plate or the top plate is bound, a steel plate (8) on a buried water stop hoop (7) on the other side is tightly attached to a polystyrene board (4) to form certain extrusion, and then spot welding is carried out on the water stop hoop (6) on the other side and a second longitudinal reinforcement (10) on the other side, so that the position of the water stop hoop is firmly fixed.
