COIL MOLDING INSTALLING METHOD, LINING METHOD, AND REGENERATION PIPE

摘要

PROBLEM TO BE SOLVED: To enable an efficient installation of a coil molding within an existing pipe to be carried out.SOLUTION: A diameter of a coil molding (10) is reduced since a helical pitch of the coil molding is increased when the extremity end of a wire (12) for a coil forming the coil molding is pulled in an axial direction, and then the coil molding is drawn into an existing pipe (100). It is possible to arrange the wires for the coil in the existing pipe while a space between the coil wires is narrowed by gathering in the wires for the coil of the drawn coil molding together in sequence from the head.
