ABSTRACT:
There is provided a pipe lining method wherein a lateral pipe lining material and a main pipe lining material are securely joined. After a lateral pipe has been lined, a start liner is applied to the main pipe and a main pipe lining material is then inserted. A heating wire for melting the start liner is mounted on a surface of a flange of the lateral pipe lining material during or after lining of the lateral pipe. While the main pipe is being lined, the heating wire is heated to melt the start liner existing between the flange of the lateral pipe lining material and the main pipe lining material. When the resin in the main pipe lining material is cured, the main pipe lining material and flange of the lateral pipe lining material are integrated. This allows the lateral pipe lining material and main pipe lining material to be reliably joined.
