Japanese Patent JP2000079637
Kind Code:
A
Abstract:

To provide a method for lining a pipe which can surely prevent the generation of wrinkles in a pipe lining material in the bent part of a pipe line.

A tubular fluid pressure-pressed liner 8 is arranged in a branch pipe lining material (pipe lining material) and drawn, a fluid pressure is supplied into the liner 8, and while wrinkles 1a, 1b generated in the branch pipe lining material in the bent parts A, B of a branch pipe (pile line) 21 are being pressed by the liner 8, a thermosetting resin contained in the branch pipe lining material is cured. Since the width of the liner 8 expanded by a fluid pressure is not contracted even in the bent parts A, B of the branch pipe 21, the entire wrinkles 1a, 1b generated in the branch pipe lining material in the bent part A, B of the branch pipe 21 are pressed effectively by the expanded liner 8. Accordingly, the generation of wrinkles in the bent parts A, B of the branch pipe 21 is prevented surely.
