PROBLEM TO BE SOLVED: To provide a fitting method of an anticorrosive core which determines that the anticorrosive core is reliably fitted at a proper position on a boring part and, thereafter, can complete a boring processing operation.SOLUTION: In a fitting method of an anticorrosive core, a fluid pipe 1 is bored in an interrupted flow state by using a casing 2 which hermetically surrounds the fluid pipe 1, an operation valve 3 and a boring operation device 4 and an anticorrosive core 5 is fitted at a proper position of a boring part 1a of the fluid pipe 1. Therein, the boring operation device 4 is attached to the operation valve 3 fitted to the casing 2, the operation valve 3 is opened, the boring part 1a is perforated on the fluid pipe 1 by a boring implement 4a extended from the boring operation device 4, such an operation as to fit the anticorrosive core 5 to the boring part 1a is performed, an image gaining device 6 is directly derived near the boring part 1a of the fluid pipe 1 by using an introduction opening 12 formed on a casing 2 lateral part in a space between the fluid pipe 1 and the operation valve 3 and a correction operation of a fitting position of the anticorrosive core 5 is performed while determining whether the anticorrosive core 5 inserted to the boring part 1a is fitted to a proper position. |
