Irradiating light from inside the tubular lining material of a not yet hardening state where it is introduced the light irradiation device for the pipe conduit repair lining material

摘要

PROBLEM TO BE SOLVED: To provide a device for irradiating a pipeline repair lining material for rehabilitating an existing pipe by the tubular lining material accurately by using light emitting diodes.;SOLUTION: This device is provided with a cylindrical main body device 12 constituted to run in the inside of the tubular lining material 40 being not yet cured and introduced along an internal wall of the existing pipe to be repaired, a plurality of light emitting diodes 14 provided on an outer surface of the main body device 12 to apply light outward and mounted at an equal interval at least in the peripheral direction of a device main body, and traveling mechanisms 16, 18 for letting the main body device 12 run in the tubular lining material 40. Consequently, it is possible to achieve the advantages obtained when using the light emitting diodes such as efficient photo-curing work by reduced electric power consumption, simplification of a structure of this device, prolongment of service life of this device, and uniform irradiation of the pipe owing to this configuration.;COPYRIGHT: (C)2009,JPO&INPIT
