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： 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： 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 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 repair assembly and method of use is provided. The repair assembly includes a liner assembly for repairing a pipe system including a first pipe, a second pipe extending from the first pipe, and in some embodiments a third pipe extending from the second pipe. The third pipe may include multiple pipes. The repair assembly further includes a bladder assembly. The liner and bladder assembly are configured to work together to be positioned within the first, second, third and any additional pipes to line and repair all of the components of the pipe system in a single repair. Such repair will reduce the amount of time required to repair such pipe systems, and will increase the efficiency of repairing pipes.

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.

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 curved plate extends along an arc of the outer surface of the curved plate that corresponds to a central angle of the pipe less than or equal to 180°. The curved plate includes a concave surface with a radius of curvature less than a radius of curvature of the outer surface of the pipe so as to bias the curved plate against the outer surface of the pipe when the curved plate is flexed to engage the 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 means for repairing the junction of a main and lateral pipe are provided. A repair assembly includes a launcher device, a bladder assembly surrounding the launcher device, and a liner assembly surrounding the bladder assembly. The bladder assembly is frangibly connected to the launcher device to maintain the position of the bladder assembly relative to the launcher device during transport and positioning of the assembly. Likewise, the liner assembly, which includes main and lateral liner members, is frangibly connected to the bladder assembly. The frangible connections allow the position of the repair assembly to be maintained. The frangible connections can be broken, such as by inflation and/or tearing or pulling apart of the components of the repair assembly. Thus, the invention provides a way to mitigate the movement of components of the repair assembly during transport and positioning of the repair assembly.

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.
