WATERPROOF METHOD IN JOINTING POINT OF CONCRETE STRUCTURE

摘要

A joint water proofing method is provided to extend the lifespan of the structure since simple process makes efficient waterproofing possible. A joint water proofing method comprises following processes: an injection hole boring process punched in the outer side of structure to the water stop(S1); an injection nozzle inserting process putting the casing in which the polyurethane foam is formed in the outer circumference into the injection hole(S2); an injection device mounting process mounting packer to the backend of casing(S3); a sealant charge process filling sealant with packer in the injection hole(S4).
