<p>PURPOSE: To easily repair a cable by forming holes for inserting a plurality of cables in the longitudinal direction of a main pipe body in a resin filled after curing a reactive curing resin liquid inside an airtight layer disposed in the inner surface of the main pipe body. CONSTITUTION: The existing pipeline buried in the ground is used for a main pipe body 1. A flexible plastic tube or pipe is used for an airtight layer 2. Also, one in which an airtight plastic tube is pasted to the inner surface of a cylindrical cloth or nonwoven fabric cloth is used for the airtight layer 2. The airtight layer 2 is bonded to the main pipe body 1 by a bonding agent or stuck to the inner surface of the main pipe body 1. A resin 3 obtained by curing a reactive curing resin liquid is put inside the airtight layer 2 to form a plurality of cable inserting holes in the longitudinal direction of the main pipe body 1. It is desirable that the inner surface of the holes 4 is lined with an individual tube 5. Thereby, the damaged part of the main pipe body 1 is repaired and at the same time, a cable is easily inserted.</p> |
