<p>PROBLEM TO BE SOLVED: To provide a repairing method, having a constitution in which workability is improved and the number of parts is reduced. SOLUTION: In this method for repairing a corrosion spot 1A of an existing pipe 1, after the corrosion spot 1A is filled with a sealing a sealing material 2, such as a bond, a corrosion-proof tape 3 is wound and a covering tube 4, having an inside diameter large enough to allow formation of a space S for filling with resin forming a closed space at the outside of the wound tape 3, is mounted on the covering tube 4. Thereafter, the space S is filled with curable resin 7. After the filled resin 7 is cured, the outer periphery of the covering tube 4 is covered by winding corrosion tapes 8 and 9.</p> |
