| titleOfInvention | A pipe liner, a liner product and methods for forming and installing the liner |
| abstract | A method for lining, rehabilitating, repairing, and rejuvenating pipelines and passageways is disclosed. The method comprises the steps of hauling a tubular liner (10) into a section of pipeline (14) to be repaired, disposing a reforming member (34) within the liner at one end proximate one end of the pipeline, depositing a cement slug (16) in the host pipeline proximate the said one end, and expanding the liner within the pipeline against the inner surface of the said pipeline by urging the reforming member along within the liner under pressure. The outer surface of the liner is provided with a plurality of protrusions (12) in the form of grout anchor hooks which penetrate the cement along the length of the said liner thus ensuring a mechanical bond between said liner and said cement. The cement also adheres to the inner surface of the pipeline and thus a rigid, secure, water impermeable lining construction is achieved. The anchor hooks both prevent gravitational slump of the mortar, and also ensure that the liner does not fall from the cement. A substantially uniform thickness of cement is obtained, and the lining constructions adopts a substantially identical shape to that of the host pipe after the cement has hydrated. |
