Abstract
A flexible tubular pipe-lining material impregnated with a thermosetting resin is sandwiched by sandwiching steel belts in order to impart elasticity and rigidity thereto. A leading steel belt for leading the pipe-lining material is fixedly attached to the distal end thereof and the sandwiching steel belts. A drawing steel belt is removably attached to the leading steel belt to draw the pipe-lining material into a pipeline to be repaired. Additionally, an auxiliary steel belt is attached to the pipe-lining material to support the insertion thereof into the pipeline. The pipe-lining material can be inserted into the pipeline by the sandwiching steel belts, the drawing steel belt and the auxiliary steel belt. Such an arrangement allows the pipe-lining material to be easily and smoothly inserted into the pipeline even where there is a plurality of sections bent at a right angle or close to a right angle.
