<p>A new process and new device permit the repair of damaged pipes in which debris formation occurs or in which pipe sections are completely destroyed. The device can be mounted on a pipe-repair robot or on a conventional chariot and remote-controlled by a television camera. A noble metal lining (1) is introduced into the pipe interior by the device, which is equipped with a simple locking mechanism (4). The lining is then pushed to the site of damage or of a missing pipe section and a sealant is forced through holes in the lining toward the exterior.</p> |
