    摘要： An apparatus and a method for forming a lining in a pipe is disclosed. A pumpable material capable of curing is dispensed about an interior wall of a damaged section of pipe between an inflatable bladder and the pipe. The pumpable material is compressed between the bladder and the pipe and allowed to cure. An assembly for forming the lining in the pipe includes a feeding pump, a static mixer, a dispensing unit and a bladder. The pumpable material is preferably dispensed rearward of an inverting face of the bladder and the dispensing unit and the bladder move substantially in sync along the interior of the pipe.

    摘要： A method of providing a seal between pipe liners in a pipe, or at the juncture between a main and lateral pipe is provided. A first liner, which has been impregnated or otherwise coated with a resinous material capable of curing and hardening, is positioned in a pipe about an area in need of repair. A second liner, also including the resinous material, is place in the same pipe, with a portion of the second liner overlapping a portion of the first liner. A sealing member, such as a hydrophilic or hydrophobic band or material, is placed between the two liners at the overlap to seal the connection of the two liners.

    摘要： The present invention is an improved method and assembly for repairing a pipe or the junction of two pipes, such as sewer pipes. The assembly includes a launcher device having a launcher device body, a launcher device opening disposed on the launcher device body, and a main bladder substantially surrounding the launcher device body. The main bladder includes an opening that substantially aligns with the launcher device opening. The assembly further includes an absorbent liner and a lateral bladder having a tubular lateral bladder body portion and a flange portion. The flange portion of the lateral bladder is attached to the exterior of the launcher device body. A method of using the assembly includes impregnating the liner with resinous material; inserting at least a portion of the liner into the lateral bladder; inflating the bladders; pressing the liner against the pipe; and allowing the resinous material to cure and harden.

    摘要： A manhole liner and a method of using the same are provided. The manhole liner is sized substantially equally to the largest diameter of the manhole, so that the liner does not have to stretch to be pressed against the manhole wall. Additionally, the liner is impregnated with a resinous material capable of curing and hardening. A bladder, preferably stretchable circumferentially and having a diameter less than the smallest diameter of the manhole, is inserted into the liner. The bladder is expanded to press the liner against the wall of the manhole to dispense resinous material from the liner, while the liner is able to fold over itself in areas having a diameter less than the original diameter of the liner. Because the bladder stretches to produce a smooth outside surface, the resinous material will migrate to areas in the folds and will cure with a smooth interior surface.

    摘要翻译： 提供了一种人孔衬板及其使用方法。 人孔衬板的尺寸基本上等于人孔的最大直径，使得衬垫不必拉伸以压靠在井壁上。 此外，衬里浸渍有能够固化和硬化的树脂材料。 优选地沿圆周方向可拉伸并且具有小于该孔的最小直径的直径的囊状物被插入衬垫中。 囊膨胀以将衬垫压在人孔的壁上以从衬里分配树脂材料，而衬里能够在具有小于衬套的原始直径的直径的区域中折叠自身。 因为气囊伸展以产生光滑的外表面，所以树脂材料将迁移到褶皱中的区域并且将以光滑的内表面固化。

    摘要： A method of repairing and renewing a manhole chimney utilizes a circumferentially stretchable liner sleeve which is inserted into the manhole and pressed by an inflatable bladder into engagement with the walls of the manhole chimney. The sleeve is coated with an uncured resin, which is allowed to cure as the sleeve is pressed against the chimney walls, thereby attaching the sleeve to the walls of the manhole chimney. The stretchable sleeve eliminates air spaces between the sleeve and the chimney walls, and precludes formation of undesirable folds in the sleeve. The sleeve stretches circumferentially up to 150% of its unstretched diameter, while having a substantially unstretchable length.

    摘要： A pipe repair apparatus includes an outer carrier tube, an inner bladder tube within the carrier tube, and a repair sleeve within the bladder tube. The bladder tube and the carrier tube are formed by one unitary tube which is folded back upon itself. A wick extends from the repair sleeve to the rear end of the bladder tube and permits evacuation of gases from the bladder tube when the bladder tube is flattened by a vacuum during insertion of a curable resin into the bladder tube at its forward end. The bladder tube can be inverted out of the carrier tube so as to place the repair sleeve in contact with an area to be repaired within a sewer pipe. This method may also be used to repair the damaged joint between a lateral sewer line and a main sewer line.

    摘要： The invention utilizes temperature sensing to measure the internal temperature of an underground structure, such as a pipe, for the purpose of determining a proper cure interval and/or mix ratio of a resin system during a lining operation. A temperature sensor is placed within a pipe or other underground structure to be rehabilitated and at least one temperature measurement is taken within the structure prior to or simultaneously with the installation of a liner. Once the temperature of an internal aspect of the structure is taken, a cure schedule is utilized to determine the appropriate curing time based on test data obtained from baseline tests performed under simulated conditions in a soil cell apparatus. A computer program may be utilized such that upon entering the type of resin, the lowest recorded temperature of the structure, and the initial resin temperature, a cure schedule is supplied.

    摘要： The method for rehabilitating a damaged section of a pipe without a need for a resin absorbent liner is provided. The method includes pumping a low viscosity material towards a damaged section of pipe and changing the viscosity prior to dispensing of the material. For example, the material may be partially cured prior to dispensing. The partially cured or higher viscosity material is compressed between an inflating bladder and interior wall of the pipe, and the material that is allowed to fully cure. The bladder either can then be removed from the pipe or could be allowed to maintain in the pipe providing a new interior surface for the repaired pipe.
