<p>PROBLEM TO BE SOLVED: To realize the irradiation of enough light energy over the inner peripheral surface of a branch tube by a method wherein a second tubular part, which is expansible and contractible to the r radial outward direction of a radially expansible and contractible first tubular part provided in a device main body, is provided integral with the first tubular part and a light energy emitting lamp and reflectors are provided in the first tubular part. SOLUTION: To both the side covers of a device main body, both the end parts of a first tubular part 3 made of an expansible and contractible lighttransmissible rubber material is fixed airtightly. In addition, at the axially intermediate part of the first tubular part 3, a second tabular part 4 made of an expansible and contractible light transmissible rubber material is integrally and radially outwards projected in a T-like shape. To the connecting plate 24 of the side covers, a container 5, at both the ends of which reflectors 31 are provided and further within which a light energy emitting lamp 6 is housed, is fixed. Further, through a tubular part air introducing means 4a, compressed air is fed in the first and the second tubular parts 3 and 4, resulting in fixing a reinforcing cloth 8 onto the inner surface of a tube to be repaired 9 by pressure and advancing the second tubular part 4 in a branch tube 9b. Finally, the light energy emitting lamp 6 is lit.</p> |
