摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method of inspecting a pipe liner bag is provided for efficiently and accurately performing in parallel inspections for a hardened condition and air-tight sealing effect of the pipe liner bag. A main pipe and a branch pipe are lined with hardened pipe liner bags, and then all open ends of the pipe liner bags are air-tightly sealed by air plugs to define an air-tight sealed space S within the pipe liner bags. Then, while the pressure within the sealed space is decreased, the inspections are made for a hardened condition and air-tight sealing effect of the pipe liner bag. If the pipe liner bag includes incompletely hardened portions, such portions will be deformed due to compression buckling, so that the deformed portions can be readily found by a TV camera equipped with a light emitting unit. In this manner, a hardened condition of the pipe liner bag can be accurately inspected. Also, if the pipe liner bag do not provide a sufficient air-tight sealing effect, the inner pressure within the sealed space will be increased, so that monitoring the inner pressure within the sealed space by a vacuum gauge permits an inspection to be readily and accurately made for an air-tight sealing effect of the pipe liner bags.

摘要： A method and apparatus for lining a branch pipe 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 conventionally required sealed tube. An open end of the pressure bag is attached to a set nozzle made of a magnetic material coupled 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 includes a magnetic plate so as to be magnetically connected to the set nozzle by a magnetic force of a magnet provided for the work robot. 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 magnet is turned off to remove the work robot and the pressure bag from the branch pipe liner bag.
