MULTI-PACKER FOR REPAIRING CRACKS OR BACKSIDE WATER BARRIER AND METHOD FOR REPAIRING CONCRETE STRUCTURE USING SAME

摘要

The present invention relates to a multi-packer for repairing cracks or a backside water barrier and a method for repairing a concrete structure using the same. The purpose of the present invention is to provide the common multi-packer for repairing the cracks or the backside water barrier and the method for repairing the concrete structure using the same capable of capable of supplying a differential-liquid repairing solution after uniformly mixing the differential-liquid repairing solution with a screw inserted therein while supplying the differential-liquid repairing solution at a low pressure or a high pressure depending on a degree of the cracks of the concrete structure. A configuration of the present invention includes: a packer body wherein a compressing unit and a repairing solution transferring pipe are integrally formed; an injection pipe or an extended injection pipe joined to the packer body and inserted into an insertion hole formed in a concrete surface to supply the repairing solution to the cracks or a damaged part of the backside water barrier; the screw inserted into the repairing solution transferring pipe of the packer body; a ball positioned in a rear end of the screw and blocking one end of a nipple in case of a backflow of the repairing solution; and the nipple having one end coupled to the other end of the solution transferring pipe and the other end wherein a repairing solution supply pipe is inserted. The multi-packer for repairing the cracks or the backside water barrier made of an injection-molded synthetic resin material and capable of being applied to cases in various crack degrees and repairing solution supply pressures and the method for repairing the concrete structure using the same.;COPYRIGHT KIPO 2017
