    Abstract: A branch pipe liner bag immune to damage caused by a cutter is provided. In the branch pipe liner bag having a flange formed at an end of a hardenable resin impregnated bag which comprises a tubular resin-absorbent material impregnated with an unhardened liquid hardenable resin, a cylindrical anti-piercing protector 3 is embedded adjacent to the flange. According to a pipe lining method implemented using the branch pipe liner bag according to the present invention, the branch pipe liner bag adjacent to the flange is, after a branch pipe is lined, protected by the anti-piercing protector, and therefore, in a piercing work thereafter of a main pipe liner bag, the branch pipe liner bag is immune from damage caused by a cutter, thereby eliminating a problem such as infiltration of the underground water into the main pipe from a damaged portion.

    Abstract: A branch pipe lining method is provided which can directly achieve an air-tight connection between a pressure bag and a branch pipe liner bag in a simple structure without employing a conventional sealed tube. An open end of the pressure bag is attached to a set nozzle attached to a work robot which is movably installed in a main pipe. A branch pipe liner bag, impregnated with a thermosetting resin, is placed inside the pressure bag. The liner bag has a flange which is removably attached to the set nozzle by fitting a protrusion formed on a surface of the flange into a concave groove formed in the set nozzle. With the flange being closely contacted to the inner wall of the main pipe around a branch pipe opening, compressed air is supplied into the pressure bag to evert and insert the branch pipe liner bag into a branch pipe. 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 is disengaged from the concave groove to remove the work robot and the pressure bag from the branch pipe liner bag.

    Abstract: A pipe liner bag is provided for reliably lining a pipe into which water may penetrate. The pipe liner bag has a double layer structure including an inner layer of a tubular nonwoven fabric made of fine yarn of three deniers or less and an outer layer of a tubular nonwoven fabric made of fat yarn of 3-15 deniers. The tubular nonwoven fabric 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 constituting the outer layer is impregnated with hardenable resin mixed with granule filler of a large diameter. After the pipe liner bag is everted and inserted into a pipe 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 is used to repair a pipe from which a branch pipe is branched off, it can be integrated with a branch pipe liner bag.

    Abstract: A liner bag for a manhole can have an improved durability after hardening with a fluid pressure barrier film left on the inner wall of a lined manhole, and a method of lining a manhole using the liner bag is capable of realizing a reduction in the number of steps involved in a manhole lining process to reduce a working time and a working cost. The liner bag for a manhole has an outer-layer liner bag including a first bag-shaped resin absorbent material, and an unhardened liquid hardenable resin impregnated in the first bag-shaped resin absorbent material, and an inner-layer liner bag including a second bag-shaped resin absorbent material, a highly air-tight plastic film coated over an inner surface of the second bag-shaped resin absorbent material, and an unhardened liquid hardenable resin impregnated in the second bag-shaped resin absorbent material, wherein the inner-layer liner bag has a thickness smaller than the outer-layer liner bag, and the inner-layer liner bag being inserted in the outer-layer liner bag. With the liner bag thus configure, since the manhole lining method performed using the manhole liner bag eliminates the necessity of stripping off the plastic film functioning as a fluid pressure barrier liner from the hardened liner bag and wasting the same, as before, it is possible to realize a reduction in the number of steps involved in the lining process, a working term, and a working cost.

    Abstract: An economical branch pipe liner bag is provided. The branch pipe liner bag allows for a reduction in manufacturing cost, stabilized quality, and mass-production, and does not have any portion to be wasted when used. One end of a tubular resin absorbent material impregnated with an unhardened hardenable resin is outwardly folded and pressed to form an extension which is sandwiched between separate flange forming members to form a flange at the one end of the tubular resin absorbent material, thus constructing the branch pipe liner bag. Since the branch pipe liner bag has the flange formed at one end by integrally coupling the flange forming members, which are members separate from the tubular resin absorbent material, the flange forming members can be mechanically mass-produced independently of the tubular resin absorbent material, with the result that a manufacturing cost of these flange forming members is reduced, and consequently a manufacturing cost of the branch pipe liner bag is reduced.
