Abstract: A pipe lining method is provided for accurately cutting or punching out a pipe liner bag after being lined on an inner wall of a pipe with a good operability while preventing an operation environment from being contaminated. A fluid pressure is applied to act on a pipe liner bag introduced in a pipe to press the pipe liner bag onto the inner wall of the pipe. A thickness reducing member is brought into contact with the outer surface of the pipe liner bag to partially reduce the thickness of the pipe liner bag. A predetermined pipe lining operation with the above state maintained. Then, an external force is applied to a thickness reduced portion of the pipe liner bag to break the portion.

Abstract: A branch pipe liner bag and a pipe lining method are provided for ensuring to securely joining a flange and a main pipe liner bag to provide a reliable integrated structure. The branch pipe liner bag comprises a tubular resin-absorbent material impregnated with an unhardened hardenable resin. The tubular resin-absorbent material is formed at one end thereof with a rigid flange which is formed with a plurality of bores. In the pipe lining method using the branch pipe liner bag, a portion of unhardened hardenable resin oozing from a main pipe liner bag enters the bores formed through the flange of the branch pipe liner bag and is hardened therein, so that the flange is securely joined with the main pipe liner bag, thereby preventing a gap from being formed therebetween. In addition, the bores may be arranged on concentric circles on the flange, and cords made of a resin-absorbent material may be passed through the bores along the inner or outer periphery of the flange. Since the unhardened hardenable resin is also impregnated into the cords, the flange is more securely joined with the main pipe liner bag. Furthermore, a portion of the main pipe liner bag located on the periphery of a branch pipe opening is protruded due to the cords, so that the protrusion facilitates the positioning of a cutter for accurately cutting a portion of the main pipe liner bag covering the branch pipe opening.

Abstract: A pipe liner bag everting nozzle is provided for allowing an operator to freely access a manhole during a lining operation. A pipe liner bag everting nozzle comprises a guide tube fixing end for fixing one end of a guide tube, and a pipe liner bag fixing end for fixing a folded end of an uneverted pipe liner bag passed through the guide tube, wherein the guide tube fixing end has a diameter smaller than a diameter of the pipe liner bag fixing end. Since a guide tube having a smaller diameter than that of a pipe line to be repaired (or the pipe liner bag) can be used, a sufficient gap is formed between the guide tube and the manhole, thereby allowing the operator to freely access the manhole during the lining operation for inspection and confirmation of a lining situation.
