A sealing cover layer is installed on the upper surface of the rubber water stop belt, a jacking column is installed on the lower surface of the sealing cover layer, a water separation groove is formed in the upper surface of the installation groove, an oil immersion cushion layer is installed in the water separation groove, and water stop belt clamping grooves are formed in the positions, located on the upper surface of the installation groove, of the two sides of the water separation groove. Through the action of the jacking columns arranged below the sealing cover layer, the center position of the rubber water-stop belt can be integrally pressurized to deform under the action of downward pressing force, the deformed rubber water-stop belt can be integrally and tightly contacted with the asphalt hemp threads, and gaps at the connecting position are reduced.
