PURPOSE: To make it possible to execute a sound anticorrosive repairing work by pushing an anticorrosive member against an anticorrosion required repairing section by hydraulic pressure in the underwater section, adhering a petrolatum anticorrosive member layer closely to the anticorrosion required repairing section and forming in above the water level.
CONSTITUTION: An anticorrosive substance 3, which is molded integrally at least 2 layers of a protective cover 1 made of the flexible materials consisting of the farthest outer layer and a petrolatum anticorrosive member layer 2 consisting of the farthest inner layer at the underside of the protective cover 1, is made in the air. A petrolatum anticorrosive member layer 5 is applied to the anticorrosion required repairing section located at a location higher than the water level in the underwater driving member 4, and then the anticorrosive member layer 2 is in contact with the anticorrosion required repairing section located at a location lower than the water level in the anticorrosive substance 3 and is fixed.
