Claims35
An assembly for repairing a hollow conduit having an inside wall surface, said assembly comprising:
- a tubular liner having a first portion and a second portion, the tubular liner impregnated with a light-activated resin;
- an inversion apparatus having an opening and a gas inlet port, wherein a seal is formed between the opening and the first portion of the tubular liner to allow inversion pressure to be communicated from the inversion apparatus to the tubular liner;
- a light curing activator having a first portion and a second portion, said light curing activator combined with the second portion of the tubular liner;
- wherein the light curing activator comprises a flexible hollow tube having an outside surface and a plurality of lights inside a water tight translucent sleeve combined with the flexible hollow tube, the flexible hollow tube adapted to expand under pressure from a first position wherein the plurality of lights are farther from the inside wall surface of the hollow conduit to a second position wherein the plurality of lights are closer to the inside wall surface of the hollow conduit.
An assembly for repairing a hollow conduit having an inside wall surface, said assembly comprising:
- a tubular liner impregnated with a light-activated resin;
- an inversion bladder having a first portion and a second portion;
- an inversion apparatus having an opening and a gas inlet port, wherein a seal is formed between the opening and at least one of the tubular liner and the inversion bladder to provide inversion pressure between the inversion apparatus and at least one of the tubular liner and the inversion bladder;
- a light curing activator having a first portion and a second portion, said light curing activator combined with the second portion of the inversion bladder;
- wherein the light curing activator comprises a flexible hollow tube having an outside surface and a plurality of lights inside a water tight translucent sleeve combined with the outside surface of the flexible hollow tube.
An apparatus for repairing a hollow conduit having an inside wall surface, said apparatus comprising:
- a light curing activator having a first portion and a second portion, said light curing activator adapted to be combined with one of a liner tube and an inversion bladder;
- wherein the light curing activator comprises a flexible hollow tube having an outside surface and a plurality of lights inside a water tight translucent sleeve combined with the outside surface of the flexible hollow tube, the flexible hollow tube adapted to expand under pressure from a first position wherein the plurality of lights are farther from the inside wall surface of the hollow conduit to a second position wherein the plurality of lights are closer to the inside wall surface of the hollow conduit.
An apparatus for repairing a portion of hollow conduit having a wall, said apparatus comprising:
- a pipe rehabilitation packer having a bladder configured to expand toward the wall, wherein the bladder is translucent, tubular, and flexible;
- and
- a light curing activator positioned within the bladder;
- wherein the light curing activator has a length and is configured to receive power at more than one location along the length.
