Abstract
The invention discloses an expansion joint seepage treatment structure, constructed through a waterstop strip, of an underground concrete structure and a construction method of the expansion joint seepage treatment structure. Firstly, a slant grouting pipe is buried in one side of the seeping expansion joint to below the original buried waterstop strip, and foaming waterstop agents are injected for temporary water stopping; secondly, horizontal galvanized grouting pipes used subsequently are buried on the surface of the other side of the seeping expansion joint at intervals; thirdly, a galvanized steel plate and a sealing rubber plate which each correspond to an opening and are each provided with a V-shaped folding notch are customized, the waterstop sealing rubber plate, the galvanized steel plate and a gasket and a nut of a chemical bolt are sequentially installed, and the steel plate and the rubber plate are fixed in a screwed mode so that the expansion joint can be sealed; and finally, high-viscosity non-cured rubber liquid is injected into the expansion joint with high pressure, and a high-viscosity large-deformation waterproof layer is formed. According to the treatment method, three waterproof layers are formed, the structural design is scientific and ingenious, the construction process is simple, and the cost low. Therefore leakage can be completely prevented, the deformation function of the expansion joint is reserved, and the existing problem of seepage of the expansion joint is effectively solved.
