The lining application device inside the sewage pipe and inside the sewage pipe the lining application manner

摘要

PROBLEM TO BE SOLVED: To smoothly form a lining pipe, and to prevent the generation of fluctuation in the driving condition of a corner part by arranging a second pinching and fitting mechanism at a position in rear of a first pinching and fitting mechanism, which is formed of an outer surface roller and an inner surface roller arranged at each connecting position of a lining pipe and a belt-like member, through a bend part. SOLUTION: In a closing part of a belt-like member 100, a new belt-like member 100 to be continuously supplied to a starting lining pipe with the fitting structure by the pinching and fitting force of an inner surface roller 5 and an outer surface roller 6 of a pinching and fitting mechanism to be driven for rotation. When a first feeding roller 73A of a first pinching and fitting mechanism 7A achieves a corner of a pipe conduit P having a rectangular cross section, a second feeding roller 73B of a second pinching and fitting mechanism 7B maintains the abutment on the wall surface so as to always maintain the feeding word. With this structure, generation of abutment of the outer surface roller 6 of the pinching and fitting mechanism on the wall surface is prevented, and while a lining pipe R can be smoothly formed by the feeding work with the generation of abutment of the feeding roller with the wall surface.
