PROBLEM TO BE SOLVED: To provide a lateral pipe-lining method for lining a lateral pipe by bringing a flange of a lateral-pipe lining material into close contact with the periphery of a lateral pipe opening of a main pipe and a flange-pressing implement used for the method.
SOLUTION: The lateral pipe 31 that intersects a main pipe 30 is lined using the lateral pipe-lining material having the flange 3 formed at one end of a resin-absorbing material 2 impregnated with a thermosetting resin. The flange of the lateral lining material is disposed on the expandable flange-pressing implement 70. The flange-pressing implement is expanded by feeding hot water to the flange-pressing implement to press the flange of the lateral pipe-lining material against the periphery of the a lateral pipe opening of the main pipe. The flange 3 is bonded to the periphery 30a of the lateral pipe opening of the main pipe by heating and curing an adhesive 82 on the flange 3 in this state by hot water. A gap does not occurs between the flange of the lateral pipe-lining material and the periphery of the lateral pipe opening of the main pipe, and accordingly, neither underground water nor earth or sand from the ground flows into the main pipe and the drainage performance of the main pipe can be improved.
