    • 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.
    • 提供了一种管道衬里方法,其中侧管衬里材料和主管衬里材料牢固地接合。 在侧管已经排出之后,将起动衬套施加到主管,然后插入主管衬里材料。 用于熔化起始衬套的加热丝线在侧管的内衬中或之后安装在侧管衬里材料的凸缘的表面上。 当主管正在衬里时,加热线被加热以熔化存在于侧管衬里材料的凸缘和主管衬里材料之间的起始衬套。 当主管衬里材料中的树脂固化时,主管衬里材料和侧管衬里材料的法兰被集成。 这样可以使侧管衬里材料和主管衬里材料可靠地接合。
