摘要:
A pipe repair apparatus includes an outer carrier tube, an inner bladder tube within the carrier tube, and a repair sleeve within the bladder tube. The bladder tube and the carrier tube are formed by one unitary tube which is folded back upon itself. A wick extends from the repair sleeve to the rear end of the bladder tube and permits evacuation of gases from the bladder tube when the bladder tube is flattened by a vacuum during insertion of a curable resin into the bladder tube at its forward end. The bladder tube can be inverted out of the carrier tube so as to place the repair sleeve in contact with an area to be repaired within a sewer pipe. This method may also be used to repair the damaged joint between a lateral sewer line and a main sewer line.
