Document Type and Number:
Japanese Patent JP2002521996
Kind Code:
A
Abstract:
One or more electric and/or data transmitting cables are confined in an elongated strip-shaped body containing a hardenable resin or the like, and the body is placed against a portion of the internal surface of an underground sewage, water or other pipe. An expandible tubular liner is thereupon introduced into the pipe and is expanded to press the body against the pipe. The body is caused to set, by conveying a hot fluid through the liner and/or by electrically heating the cable or cables, and to adhere to the internal surface of the pipe. The liner can remain in the pipe and can be bonded to the strip-shaped body and/or to the remaining portion of the internal surface of the pipe. Alternatively, the liner is caused to collapse and is withdrawn from the pipe once the strip-shaped body is bonded to the internal surface of the pipe.
