REPAIRING METHOD OF LINEAR CRACKING SECTION OF CONCRETE WALL AND JOINT SEALING METHOD IN JOINT OF CONCRETE WALL

摘要

PROBLEM TO BE SOLVED: To repair a cracking section of a concrete structure by a strong method, or to seal the joint forming part of the concrete structure by a method having high endurance.;SOLUTION: After forming a linear scraped groove 3 which is constituted by forming a narrow scraped groove 3A placed on the entrance side having a predetermined width A and a predetermined depth B and a wide scraped groove 3B having a width C larger than that of the narrow scraped groove 3A continuously with each other in the depth direction in the linear cracking 2 part of the concrete wall 1, repairs are made by filling a sealing material 11 such as mortar, resin or the like into the linear scraped groove 3. Alternatively, after forming a linear scraped groove 23 which is constituted by forming a narrow scraped groove 23A placed on the entrance side having a predetermined width A and a predetermined depth B and a wide scraped groove 23B having a width C larger than that of the narrow scraped groove 23A continuously with each other in the depth direction in the joint forming part 21 of the concrete structure 20, sealing is performed by filling a sealing material 41 such as mortar, resin or the like into the linear scraped groove 23.;COPYRIGHT: (C)2011,JPO&INPIT
