<p>A first thermoplastic external hose-like inliner (3) having a thermoplastic internal hose-like inliner located therein is introduced into a channel (1) to be repaired. The thermoplastic internal hose-like inliner has, at an external side thereof, devices for securing a pre-set spacing, thus forming an annular space in between the inner inliner and the first thermoplastic inliner (3). Then, the annular space in between the inner inliner and the first thermoplastic inliner (3) is filled with a hardenable material which is consequently set to a solid tubular shell. The apparatus has a thermoplastic internal inliner and a first thermoplastic external hose-like inliner (3). The thermoplastic internal inliner is inserted into the first thermoplastic hose-like inliner (3) and has, at the external side thereof, devices for securing a pre-set spacing between the thermoplastic external hose-like inliner (3) and for anchoring with a shaped joint of the thermoplasti internal hose-like inliner in the hardenable material located in the annular space between the thermoplastic internal inliner and the first thermoplastic external hose-like inliner (3).</p> |
