摘要

PROBLEM TO BE SOLVED: To provide a pipe line inner peripheral side intermediate, a pipe line inner peripheral side structure, and a pipe line lining method, in which a device that prevents a thermosetting resin from leaking into a branch pipe is accomplished.SOLUTION: A backing material 11 that is arranged in the extending direction of a main pipe 20 from at least a bottom 20a1 in an inner peripheral surface 20a of the main pipe 20 in which a mounting pipe 22 is mounted to a connecting opening 20b to a position at which the connecting opening 20b is disposed, and a sheet member 12 that extends in the extending direction of the main pipe 20 between the backing material 11 and the bottom 20a1 of the inner peripheral surface are included, the backing materials 11 is impregnated with a thermosetting resin, and the sheet member 12 is located not only between the backing material 11 and the bottom 20a1 of the inner peripheral surface but also between the backing material 11 and the connecting opening 20b.SELECTED DRAWING: Figure 8
