    Abstract: A resin injection method and a pipeline repair method are provided for smoothly and rapidly performing setting of an open liner and for completing works such as eversion and insertion of the open liner even for a steeply inclined pipeline. An end portion of an open liner is everted such that the end is attached to one end of a pipe liner bag which has been introduced into a pipeline to be repaired. A resin is injected into the open liner from the other end thereof while the pipe liner bag is evacuated, thus injecting the resin into the pipe liner bag through the open liner. After the resin has been injected into the pipe liner bag 1 in the above-mentioned method, the open liner is everted by fluid pressure to be inserted into the pipe liner bag, whereby the resin is impregnated into the pipe liner bag. Then, the pipe liner bag is pressed against the inner wall of the pipeline 4, in which state the resin impregnated in the pipe liner bag is cured to repair the pipeline. This pipe repair method allows the pot life of the resin to be shortened, so that a work term required for the repair operations can be reduced.

    Abstract: 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.

    Abstract: 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.

    Abstract: A method of manufacturing a pipe liner bag which is composed of a tubular resin absorbent material having an outer surface covered with a highly air-tight plastic film and a hardenable resin impregnated in the tubular resin absorbent material. The method involves folding a strip-shaped resin absorbent material and aligning both ends thereof in the width direction, straight sewing overlapped portions to form a tubular resin absorbent material while leaving a sewing margin, turning the tubular resin absorbent material inside out such that a previous inner surface thereof appears outside, and welding or adhering a plastic film entirely or partially on the outer surface of the tubular resin absorbent material to air-tight seal the outer surface. The method can reduce a time required for a joining operation and simplifying a sealing operation after both ends of the strip-shaped resin absorbent material have been joined.

    Abstract: A branch pipe lining bag wherein an annular protective member is previously fixed on a flange which is provided adjoined to an open end of a tubular bag. This tubular bag is soaked with a hardenable liquid resin and adapted to be everted under fluid pressure into a branch pipe. The protective member can be attached on the marginal periphery of the branch pipe opening to the main pipe simultaneously at the end of the branch pipe lining, irrespective of the inner diameter of the main pipe. Also, a pipe lining method wherein the annular protective member fixed on the flange is prepared previously and then the flange is connected to the part of the main pipe where the branch pipe opens. The main pipe lining bag can be bored without any damage irrespective of both the main pipe diameter and the branch pipe diameter or any connecting situations.

    Abstract: A pipe lining method is provided for simply positioning a flange of a branch pipe liner bag to a branch pipe opening of a main pipe in a short period of time, and preventing the branch pipe liner bag from having a locally insufficient strength. A branch pipe liner bag is everted and inserted into a branch pipe with a fluid pressure. With the branch pipe liner bag pressed onto the inner wall of the branch pipe, a hardenable resin impregnated in the branch pipe liner bag is hardened to line the branch pipe. Then, a main pipe liner bag is everted and inserted into a main pipe with a fluid pressure. With the main pipe liner bag pressed onto the inner wall of the main pipe, a hardenable resin impregnated in the main pipe liner bag is hardened to line the main pipe. The fluid pressure acting inside the main pipe liner bag is adjusted such that a portion of the hardenable resin impregnated in the main pipe liner bag is oozed out. The oozed hardenable resin is introduced into a clearance space, and hardened therein.

    Abstract: A method of everting a pipe liner bag into a pipeline which enables smooth eversion of a pipe liner bag using a minimally required amount of lubricant. When a pipe liner bag including a resin absorbent material impregnated with a hardenable resin and a plastic film covering the outer surface of the resin absorbent material is everted into a pipeline using a fluid pressure, the pipe liner bag is applied with oil (lubricant) on the outer surface thereof. Since the application of oil is performed immediately before everting the pipe liner bag, the pipe liner bag can be smoothly everted into the pipeline only using a minimally required amount of oil.
