<p><P>PROBLEM TO BE SOLVED: To provide a regeneration method capable of surely fixing a pipe opening saddle to a mounting pipe opening even if the inside of a main pipe or the circumference of the mounting pipe opening is in a very bad deterioration state in regeneration work fixing the pipe opening saddle to the mounting pipe opening. <P>SOLUTION: The regeneration method of the mounting pipe opening 5 is so constituted that the pipe opening saddle 1 equipped with a cylindrical sleeve 11 and a collar-shaped flange 12 projected from one end edge of the sleeve 11 is conveyed inside of the main pipe 4 in a state to mount it on the surface of a regeneration sheet 2 formed by infiltrating an ultraviolet radiation curing resin into a glass fibrous-made basic material, and after the flange 12 of the pipe opening saddle 1 and the regeneration sheet 2 have been pressed to the inside of the main pipe 4 around the mounting pipe opening 5 while inserting the sleeve 11 of the pipe opening saddle 1 in the mounting pipe opening 5, the ultraviolet radiation is irradiated to the regeneration sheet 2 to make it cure and that the pipe opening saddle 1 is fixed to the mounting pipe opening 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
