A method for hardening a rehabilitating pipe for trenchless pipe repair is provided to shorten the time required for hardening a reinforcement tube, to protect a connecting pipe and an opening of a reinforcement tube not to be damaged by steam temperature and to increase the hardening quality of a reinforcement tube. A method for hardening a rehabilitating pipe for trenchless pipe repair comprises the steps of: inverting and placing a reinforcement tube(30) impregnated with thermosetting resins in a water supply and drainage conduit through a connecting pipe(40) and a connecting holder(45) using an inversion device, unfastening a fastener of the connecting holder located in the opening of the reinforcement tube fitted to the water supply and drainage conduit, inserting a steam pipe(50) through a coupling holder(60) coupled to the connecting holder to make the front end of the steam pipe located in the reinforcement tube and fixing the fastener, connecting the steam pipe to a steam supplier and supplying steam deep into the reinforcement tube, thereby hardening the reinforcement tube. |
