Pipeliner bladder assembly

A pipeliner bladder assembly comprising:

• an elongate light carrier formed on an axis, an external surface of the light carrier aligned to and radially outwardly spaced from the axis, the light carrier having axially spaced apart proximal and distal ends and a first lumen extending from the proximal end to the distal end;
• at least one LED light string helically wound on the external surface of the light carrier;
• a bladder disposed radially exteriorly of the light string and having a proximal end and a distal end;
• a liner disposed radially exteriorly of the bladder and being impregnated with a resin curable by radiation from the LED light string;
• a flexible push rod loosely inserted from the proximal end of the light carrier to the distal end of the light carrier through the first lumen, the push rod having proximal and distal ends;
• an air head disposed axially proximally from the proximal end of the light carrier but not being directly connected to the light carrier, the air head having an axially aligned surface to which the proximal end of the bladder is sealed, ports in the air head communicating to an interior of the bladder to inflate and deflate the bladder;
• and
• a pull head disposed axially distally from the distal end of the light carrier but not being directly connected to the light carrier, the pull head having an axially aligned surface to which the distal end of the bladder is sealed, the pull head having a distal end, a pull eye attached to the distal end of the pull head;
• wherein
• the air head has a distal end with a push rod receptacle and the pull head has a proximal end with a push rod receptacle, the proximal end of the push rod affixed to the push rod receptacle, the air head and the distal end of the push rod affixed to the push rod receptacle of the pull head, whereby the light carrier and light string are protected from tensile and compressive stresses when the light bladder assembly is pulled into or pushed into a pipe to be repaired.

A pipeliner bladder assembly comprising:

• an elongate light carrier disposed on an axis;
• a fluid-impervious bladder disposed radially exteriorly of the light carrier, the bladder being radially inflatable upon the application of pressurized gas internal to the bladder;
• a liner disposed radially exteriorly of the bladder, the liner impregnated with a light-curable resin;
• the light carrier having an exterior surface, a temperature probe mounted on the exterior surface of the light carrier;
• and
• the light carrier having a second end, a plurality of temperature probe conductors extending from the first end and coupled to the temperature probe to transmit a temperature signal therefrom.

A system for the trenchless repair of a pipe, the system comprising:

• a pipeliner bladder assembly disposed on an axis and adaptable to be pulled or pushed into a pipe to be repaired, the assembly including:
• an elongate light carrier disposed on the axis, the light carrier having an external surface radially displaced from the axis, a plurality of resin-curing radiation sources mounted on the external surface of the light carrier;
• the light carrier being hollow, having opposed first and second axial ends, and at least one lumen communicating the first axial end with the second axial end;
• an air head disposed on the axis at the first end of the light carrier and having at least one air port;
• an elongate gas-impervious bladder disposed radially around the light carrier, a first end of the bladder being sealably affixed to the air head, the air port of the air head being in fluid communication with an interior of the bladder;
• an elongate liner disposed radially exteriorly of the bladder and being impregnated with a radiation-curable resin;
• a controller having a plurality of output power conductors, a power switch of the controller selectably connecting or disconnecting at least one of the output power conductors to a source of electrical power;
• a pressurized air source of the controller connected to a first end of a pressurized air conduit, the controller operable to regulate an air pressure inside of the air conduit;
• the output power conductors disposed in an interior of the air conduit, a second end of the air conduit coupled to an inlet of the air head, a chamber of the air head connecting the inlet of the air head to at least one air port, the output power conductors terminating in a connector disposed in the chamber, second power conductors having first ends connected to the connector, the second power conductors routed through the at least one air port of the air head to the at least one lumen of the carrier and coupled to the resin-curing radiation sources to provide power thereto, pressurized air supplied through the at least one air port of the air head to inflate the bladder.
