WATER LEAKAGE REPAIR METHOD FOR STRUCTURE AND WATER LEAKAGE REPAIR MATERIAL INJECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To contrive prevention of water leakage by surely forming an impermeable layer on the ground side of a structural wall in the water leakage part of an underground structure.;SOLUTION: An injection pipe 10 having on the edge part an injection opening 1 substantially radially opened for an axial center is inserted from the inside of a structure 2, the injection opening 1 is substantially positioned on the boundary part of the rear face of a structural wall and a ground, and a repair material M is supplied through the injection pipe 10 under pressure of 3-20 MPa to be injected from the injection opening 1. An impermeable layer by the repair material M is formed on the boundary part.;COPYRIGHT: (C)2000,JPO
