A pipe conduit bundle for installation into a wellbore using horizontal drilling techniques is disclosed. The pipe conduit does not require an outer casing for construction. The pipe bundle configuration is formed by pipes of varying sizes in a particular configuration, with bindings interspaced along the length of the pipes such that the pipe bundle deflects as a single unit during installation. A pulling head is attached to the bundle, which is hollow to allow liquid entering one pipe to be distributed to other pipes. Liquids such as water may be used to fill the pipes to reduce buoyancy, and thereby reduce drag, during installation of the bundle.

Such features includes the structure of the material, such as a woven structure, and further include properties such as melting point, tensile strength, elongation, coefficient of friction, crimp resistance and compression recovery.

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 Alternatively, the liner is caused to collapse and is withdrawn from the pipe once the strip-shaped body is bonded to the internal surface of the pipe.
