摘要： A method of manufacturing a multi-layer pipe liner bag (10), wherein a guiding tube (3) is inserted into an outer layer (1) composed of a tubular resin absorbent material (1A) and a plastic film (1B) coated over the outer periphery of the tubular resin absorbent material; an inner layer (2) composed of another tubular resin absorbent material (2A) is inserted into the guiding tube, and the guiding tube is extracted with the outer layer and the inner layer being fixed; and the tubular resin absorbent resin absorbent materials of the outer layer and the inner layer are impregnated with thermosetting resin to complete the pipe liner bag. Since the outer layer and the inner layer are manufactured separately, the manufacturing of the respective layers can be performed with a good workability. Advantageously, the plastic film covering the outer surface of the outer layer can be prevented from scratches.

摘要： A bent pipe lining method which can get rid of bulky creases of the liner commonly formed at the bends of the pipe, which is characterized by the use of a flat belt (8) that is attached to the sewn-end of the liner bag (1), which pulls the flat belt inside itself as it is everted into the bent pipe (21); when the liner bag is hardened the flat belt is kept stretched so as to keep the bulky creases compressed and bent flatly.

摘要： A method for lining a manhole (2), which comprises (a) inserting into the manhole a tubular liner (7) soaked with a curable liquid resin; (b) everting an inflatable plastic bag (9) into the tubular liner by charging water in it; (c) closing the open end of the everted bag (9) to form a closed space (S) inside the bag; (d) supplying compressed air to the closed space to cause the plastic bag (9) to inflate and press the liner (7) against the manhole (2); and (e) curing the liquid resin to harden the liner (7). Further improvements include: plugging the main pipe (1) with two plugs (3, 4) to isolate the manhole and stop the drain from wetting the manhole, but providing a hose (5) penetrating through the plugs to allow the drain to flow past the manhole; partially filling the portion of the main pipe (1) isolated between the two plugs (3, 4) with a liquid absorbent filler (6); and arranging that the tubular liner (7) has varied thickness increasing toward its lower end stepwise or continuously and/or has its lower opening covered up by a net (33) attached to the lower end circumference of the liner (7).

摘要： A pipe liner bag (1) is provided for reliably lining a pipe (10) into which water may penetrate. The pipe liner bag has a double layer structure including an inner layer of a tubular nonwoven fabric (2) made of fine yarn of three deniers or less and an outer layer of a tubular nonwoven fabric (3) made of thicker yarn of 3 - 15 deniers. The tubular nonwoven fabric (2) constituting the inner layer is impregnated with highly viscous and thixotropic hardenable resin mixed with granule fillers of a small diameter, while the tubular nonwoven fabric (3) constituting the outer layer is impregnated with hardenable resin mixed with granule filler of a larger diameter. After the pipe liner bag (1) is everted and inserted into a pipe (10) to be repaired by fluid pressure, the hardenable resin impregnated in the pipe liner bag is cured while maintaining the internal pressure thereof constant. When this pipe liner bag (1) is used to repair a pipe (10) from which a branch pipe (11) is branched off, it can be integrated with a branch pipe liner bag (12).

摘要： A method is proposed for lining a branch pipe (2) from a main pipe (1), wherein a particular sealing mechanism is adopted in attaching the collar (4A) of a liner bag (4) onto the flange (7b) of a fluid pressure sealing nozzle (7). Stopper tacks (18) are embedded in the collar (4A) at appropriate locations, each of the stopper tacks having its bottom end exposed from the back face of the collar and connected with a string (19). The back face of the collar (4A) of the branch pipe liner bag (4) is faced with the upper face of the flange (7b) of the fluid pressure sealing nozzle (7), which further comprises a hollow cylindrical part (7a), the flange (7b) extending perpendicularly from the side of the cylindrical part (7a), and at least one endless sealant (16, 17) is laid on the upper face of the flange (7b). A string puller (11, 12, 13) provided in the flange (7b), and the strings (19) are engaged with the string puller, and the string puller (11, 12, 13) pulls the strings (19) so that the collar (4A) and the flange (7b) are moved toward each other until sufficient sealing effect is obtained.

摘要： A branch pipe lining method which can achieve an air-tight connection between a pressure bag (7) and a branch pipe liner bag (1) in a simple structure without employing a conventional sealed tube. An open end of the pressure bag (7) is attached to a set nozzle (10) coupled to a work robot (6) which is movably installed in a main pipe (20). A branch pipe liner bag (1), impregnated with a thermosetting resin, is placed inside the pressure bag (7), the liner bag having a flange (5) which is removably attached to the set nozzle (10) by fitting a protrusion (5a) formed on a surface of the flange into a concave groove (10c) formed in the set nozzle. With the flange (5) being closely contacted to the inner wall of the main pipe (20) around a branch pipe opening (21a), compressed air is supplied into the pressure bag (7) to evert and insert the branch pipe liner bag (1) into a branch pipe (21). While the branch pipe liner bag is pressed against the inner wall of the branch pipe, the thermosetting resin impregnated in the branch pipe liner bag is cured, whereby the inner wall of the branch pipe is lined with the cured thermosetting resin, i.e. the branch pipe is repaired. Upon completing the lining operation, the protrusion (5a) is disengaged from the concave groove (10c), the work robot (6) removed and the pressure bag (7) removed from the branch pipe liner bag (1).

摘要： A method for lining a branch pipe (3) comprising the steps of:
preparing a tubular liner bag (4) by sewing a rectangular nonwoven resin-absorbent fabric (5) into a tubular shape with one end closed; attaching an impermeable plastic film over the external surface of this tubular liner bag; soaking the nonwoven resin-absorbent fabric with a hardenable fluid resin; everting the liner bag into the branch pipe until the eversion head (4b) of the liner bag is stopped by the inner wall of the main pipe; forcing the eversion head of the liner bag to turn downstream in the main pipe, thus allowing the liner bag to evert entirely; hardening the hardenable fluid resin while inflating the liner bag; and removing that portion of the liner bag which protrudes into the main pipe.
