Abstract (en)
[origin: WO9002286A1] Provided in the present invention is a conduit liner assembly (10) for use in the installation of a series of fiber optics cables (36) in an existing conduit (12). The conduit liner assembly (10) includes a plurality of individual chambered inserts (14, 114, 214) each having a central chamber (16, 116, 216) and connected one to another in bundled engagement such that each of the inserts is longitudinally moveable individually with respect to each of the inserts adjacent thereto. Also provided is a method for installation of a conduit liner assembly in an existing conduit including the steps of connecting a group of separate tubular inserts together into a loosely held bundle wherein the separate tubular inserts are longitudinally moveable with respect to one another when connected. The bundle of inserts is next pulled through an existing conduit at a suitable access point in the conduit. The bundle is separated at the access point into separate tubular inserts. A pulling force is then applied to each of the separate tubular inserts.
