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.

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 pipe liner bag comprises 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. A plastic film is welded on a surface of a strip-like resin absorbent material. The plastic film has a width smaller than the resin absorbent material which has sewing margins in both end portions in a width direction. The resin absorbent material is folded such that the plastic film is exposed. Both edges of the resin absorbent material in the width direction are laid one on top of the other. The overlapping portions of the resin absorbent material is lock sewed to form a tubular resin absorbent material.

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 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 for maintaining a favorable surface state on the inner surface of a lined branch pipe. The branch pipe lining method utilizes a branch pipe liner bag composed of a tubular resin-absorbent material having a flange formed at one end thereof, wherein the outer surface of the tubular resin-absorbent material is covered with a highly air-tight film, and the tubular resin-absorbent material is impregnated with an unhardened hardenable resin, and a cylindrical fluid pressure sealing member attached to the inner surface of the flange. A cylindrical front end nozzle attached to an opening at one end of a pressure bag is inserting into the fluid pressure sealing member of the branch pipe liner bag, and the front end nozzle and the fluid pressure sealing member are sealed by an elastic member interposed therebetween.

Abstract: The present invention provides a method of readily manufacturing a multi-layer pipe liner bag with a good workability. A guiding tube is inserted into an outer layer composed of a tubular resin absorbent material and a plastic film coated over the outer periphery of the tubular resin absorbent material. An inner layer composed of another tubular resin absorbent material is inserted into the guiding tube, and the guiding tube is extracted with the outer layer and the inner layer being fixed. The tubular resin absorbent materials of the outer layer and the inner layer are 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. Also advantageously, the plastic film covering the outer surface of the outer layer can be prevented from scratches and so on.

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 pipe lining method provides for precise cutting of a main pipe liner bag along a branch pipe opening using a cutter while preventing the inner wall of a branch pipe and the cutter from damages. After a cutting protection member is attached along the periphery of a branch pipe opening of a main pipe, the main pipe is lined using a main pipe liner bag. Then, a cutter of a cutting robot introduced into the main pipe is driven to cut away a portion of the main pipe liner bag covering a branch pipe opening. Since the cutting protection member functions as a guide for the cutter when cutting the portion of the main pipe liner bag covering the branch pipe opening as well as functions as a protection member for protecting the inner wall of the branch pipe, thereby making it possible to precisely cut the main pipe liner bag along the branch pipe opening using the cutter and to prevent the inner wall of the branch pipe and the cutter from damages.

Abstract: A method for impregnating a resin-absorbable tubular liner with a hardenable liquid resin: (a) a hose is connected to a vacuum pump; (b) the hose is inserted into the liner in a manner such that the open end of the hose comes close to, but sufficiently distant from, one end of the liner; (c) the other end of the tubular liner is closed over the hose in a manner such that the hose can freely slide through the closed end of the tubular liner; (d) a predetermined amount of the hardenable liquid resin is injected into the tubular liner through the open end of the tubular liner; (d') the open end of the tubular liner is substantially closed by placing it between a pair of rollers; and (e) the vacuum pump is operated to evacuate the hose while at the same time the hose and/or the resin-absorbable tubular liner are moved in a manner such that the length of the hose inside the liner is reduced.

Abstract: A pipe liner bag is provided with improved anti-peeling and anti-bursting properties by ensuring a high anti-peeling strength of the plastic film to be employed. The pipe liner bag has a tubular resin absorbent material, the outer surface of which is coated with a highly air-tight plastic film, and a hardenable resin impregnated in the tubular resin absorbent material. The tubular resin absorbent material is formed of tubular unwoven fabric subjected to the needle punching processing, where a side of the tubular unwoven fabric having stuck-out needles protruding therefrom is exposed to the outside to serve as an outer surface of the tubular resin absorbent material. The outer surface is coated with a plastic film.

Abstract: A method for lining an underground sewer pipe: (a) preparing a tubular liner made of a tubular fabric layer soaked with a thermosetting liquid resin and two layers of airtight film with which inner and outer walls of the fabric layer are covered; (b) inserting the liner assembly into the tubular conduit from the front end by pulling the front end with a rope; (c) inflating the tubular liner assembly after closing the front and the rear ends thereof; (d) heating the thermosetting resin to thereby harden the fabric layer of the liner assembly; and (e) removing those portions of the tubular liner assembly which do not partake in lining the tubular conduit.

Abstract: A branch pipe liner bag is provided for reliably lining a branch pipe even having a curved portion. The branch pipe liner bag has a tubular resin-absorbent material having a flange formed at one end thereof, the outer surface of which is covered with a highly air-tight film. The tubular resin-absorbent material is impregnated with an unhardened hardenable resin, and a separable tube is attached to the flange. According to this invention, since the separable tube is attached to the previously hardened flange of the branch pipe liner bag, the separable tube will never be torn or cut even if the branch pipe liner bag is everted and inserted into a branch pipe having a curved portion with a high fluid pressure, or even if the film covering the branch pipe liner bag is heated and therefore softened by a heat medium or heat generated by the hardening of the thermosetting resin.

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.

Abstract: A tubular branch pipe liner is proposed, which has a rigid collar at its end and to this collar is attached a protector consisting of a first portion which is out-spread downwardly and curved to fit on the lower face of the collar and is fixed thereto, a second portion which is roughly cylindrical and fitted into the inner peripheral face of the collar and the inner wall of a little part of the tubular branch pipe liner which is immediately continuous from the collar, and a third portion which extends downwardly and terminates in an annular end face at a location substantially lower than the joint where the first portion and the second portion meet; also proposed is a pipe lining method, which comprises the steps of preparing a branch pipe liner with a collar; and attaching the above-mentioned protective member to the collar; and lining a branch pipe with the tubular branch pipe liner; and lining the main pipe with a conventional main pipe liner; and cutting a hole through that circular portion of the main pi

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.
