After that, the baffle 44 is no longer limited by the limiting rod 42. The force storage spring 45 will change from a compressed state to an extended state, thereby driving the pressure rod 43 to move to the side close to the water stop plate 23, so that the other side of the water stop plate 23 can be lifted, thereby increasing the distance between the water stop plate 23 and the two ground connection walls. The joint area between them is further improved; the water-stopping effect is further improved; when the pressure rod 43 moves toward the side of the waterstop plate 23, the pressure rod 43 will simultaneously drive the expansion plate 5 to move, and then the expansion plate 5 will be pressed against the side of the waterstop plate 23, and since the expansion plate 5 is semicircular in shape and made of rubber, the pressure rod 43 will drive the expansion plate 5 to expand, further improving the lifting degree of the waterstop plate 23, which is beneficial to the water-stopping of the ground-connected wall; in the process of the pressure rod 43 driving the expansion plate 5 to expand, the expansion plate 5 will simultaneously drive the expansion columns 51 on both sides thereof to rotate, and the expansion column 51 will undergo a certain degree of deflection.
