Abstract
A lateral pipe-lining method for lining a lateral pipe that intersects a main pipe. A lateral pipe-lining material has a tubular resin-absorbing material impregnated with a curable resin and has a flange formed at one end thereof. The flange is disposed on an expandable flange-pressing implement. The expandable flange-pressing implement is expanded using a heat medium that is supplied by a first fluid source and that heats the flange of the lateral pipe-lining material to bring the flange into contact with a periphery of a lateral pipe opening of the main pipe. The lateral pipe-lining material is inserted into the lateral pipe using a fluid from a second fluid source different from the first fluid source, and the curable resin impregnated in the tubular resin-absorbing material is cured to line the lateral pipe.
