LATERAL PIPE LINING METHOD AND LATERAL PIPE LINING APPARATUS

摘要

OF THE DISCLOSUREA main pipe is lined by a main pipe lining materialcomprising a resin pipe made of a thermoplastic resin. Aflange of a lateral pipe lining material is formed of a material capable of being welded to the thermoplastic resinof the resin pipe of the main pipe lining material. Thethermoplastic resins of the flange of the lateral pipe lining material and the resin pipe are heated for plasticwelding by a heater to integrally join the flange of the lateral pipe lining material with the main pipe lining material. This prevents the ingress of underground watertogether with sediment into the main pipe from the section where the lateral pipe and the main pipe intersect.Fig. 1
