摘要： The pipe access device is comprised of a curved plate adapted to engage an underground pipe along an arc of the outer surface of the pipe, and a boss extending upwardly from the curved plate about an aperture in the curved plate. The boss is adapted to receive an extension pipe. The boss includes a flange adapted to engage ad end of the extension pipe. A gasket is combined with the flange to help seal the connection between the boss and the extension pipe. The pipe access device is for use in providing access to the buried pipe that requires minimal excavation and disruption of the soil.

摘要： A method and assembly for sealing an opening in a pipe wherein the opening is a damaged/cracked section in a length of pipe or the junction between a main pipe and a lateral pipe. The assembly includes a sealing member attached to a positioning tube such as preliner. The sealing member is combined with the preliner so that when the assembly is positioned in the main pipe, the sealing member corresponds with the opening. The sealing member is sized such that it extends along the main pipe on opposite sides of the opening. A mainline liner is installed within the preliner. In some embodiments, after the mainline liner cures and hardens, a cutter is used to cut an opening in the mainline liner, preliner, and sealing member to reinstate service to the lateral pipe. The sealing member remains in place around the periphery of the lateral pipe junction to act as a water stop at the opening.

摘要： Apparatus and methods for lining a pipe line having a first pipe section in communication with a second pipe section where the first pipe section has an inside diameter greater than an inside diameter of the second pipe section. A transition tube having an outside diameter substantially equal to the inside diameter of the second pipe section and a length substantially equal to or greater than the length of the first pipe section is inverted into the pipe line along with a liner. A resinous material applied to the liner cures and hardens the liner after inversion. The transition tube creates a surface against which the liner can be compressed to help prevent the liner from being overstretched in the wider first pipe section.

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 method and system for dispensing a material through a delivery apparatus is provided. The material initially comprises or is manipulated to comprise a low viscosity. The material either can comprise a curable material or can comprise initiators, which can be activated to raise the viscosity at a later time and position. The low viscosity material is moved through the delivery apparatus for a relatively long distance using low energy. Upon nearing an end use application, the material and/or initiators can be activated by a curing agent, such as a light or heat source, such that the viscosity of the material be raised prior to the end use application thereof. Therefore, the present invention provides a method and system for moving a material normally having a higher viscosity a long distance requiring lower energy and pressure.

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 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： A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.

摘要： An assembly and method of sealing a junction of a pipe and a second structure are provided. The assembly includes a pipe liner having a tubular portion and a brim portion, and a mechanical anchor adapted to secure the brim portion of the pipe liner to the second structure. The assembly may further include a compression gasket for placement between the pipe liner and the pipe or second structure. The compression gasket may comprise a hydrophilic material, a hydrophobic material, or a compressible material. The methods of using the assembly include, but are not limited to, the use of a cured-in-place pipe liner.
