REPAIR DEVICE FOR EXISTING PIPE, AND REPAIR METHOD OF EXISTING PIPE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a repair device for an existing pipe, capable of repairing a part of an existing pipe in a simple and easy way; and a repair method of an existing pipe using the same.SOLUTION: A repair device for an existing pipe is used for repairing a part of the existing pipe laid between manholes, having a length at least approximately equal to the interval length between manholes and an outer diameter at least larger than the inner diameter of an existing pipe, including a cylindrical body 12 for guiding formed of flexible and air impermeable material, and a tubular lining material 16 formed of uncured curable member attached to the outer peripheral surface of a specified place in the extension direction of the cylindrical body 12 for guiding. Using the cylindrical body 12 for guiding, the tubular lining material 16 attached thereto can be swiftly pinpoint positioned at the object portion of the existing pipe to be repaired. A part of the existing pipe can be thus repaired without using a large-scale apparatus.
