Abstract

An underground pipe repair system is for a branch pipe connecting with a service pipe. The underground pipe repair system includes a robot device with an inflation tool, a processor, and a housing carrying the inflation tool and the processor. The underground pipe repair system also includes a liner assembly having an inverted liner including a proximal end coupled to the inflation tool, and a distal end opposite the proximal end, and an electronic curing device coupled to the distal end and within the inverted liner. The processor is configured to cause the robot device to move through the service pipe, determine a position of the branch pipe, operate the inflation tool to invert and cause the inverted liner to inflate within the branch pipe and position the electronic curing device within the inflated liner, and activate the electronic curing device to cure the inflated liner within the branch pipe.

Abstract

An underground pipe repair device is for a joint between a service pipe and a branch pipe. The underground pipe repair device may include a first T-shaped joint liner having a base portion extending laterally in the service pipe, and an arm portion extending vertically into the branch pipe. The underground pipe repair device may also include an annular body aligned with and being radially spaced from an opening for the branch pipe and coupled to the first T-shaped joint liner for enabling reinstatement of the branch pipe opening without damaging a liner in the service pipe or the first T-shaped joint liner.

Abstract

An underground pipe repair device is for a joint between a service pipe and a branch pipe. The underground pipe repair device may include a T-shaped joint liner having a base portion extending laterally in the service pipe, and an arm portion extending vertically into the branch pipe, the base portion including a first base surface facing the service pipe, and a second base surface opposite the first base surface. The underground pipe repair device may include an annular body aligned with an opening for the branch pipe and coupled to the second base surface of the T-shaped joint liner. The annular body may have a physical characteristic to be detected by a robot device within the service pipe.

Abstract

An underground pipe repair device is for a joint between a service pipe and a branch pipe. The underground pipe repair device may include a T-shaped joint liner having a base portion extending laterally in the service pipe, and an arm portion extending vertically into the branch pipe, and a retention device embedded in the base portion adjacent an opening in the branch pipe. The underground pipe repair device may include an alignment device to be coupled to the retention device, and a service pipe liner extending in the service pipe and under the T-shaped joint liner and the alignment device. The alignment device extending vertically into the service pipe so that the service pipe liner has a radial bump about the opening in the branch pipe.

The underground pipe repair device may include a first T-shaped joint liner having a base portion extending laterally in the service pipe, and an arm portion extending vertically into the branch pipe. The underground pipe repair device may include a first annular spacer aligned with an opening in the branch pipe and being coupled to an underside of the first T-shaped joint liner, a second annular spacer aligned with the opening in the branch pipe and being coupled to the underside of the first T-shaped joint liner, the first annular spacer being radially within the second annular spacer, and a third annular spacer aligned with the opening in the branch pipe and being coupled to the underside of the first T-shaped joint liner.

Abstract

An underground pipe repair device is for a joint between a service pipe and a branch pipe. The underground pipe repair device may include a first T-shaped joint liner having a base portion extending laterally in the service pipe, and an arm portion extending vertically into the branch pipe, and a second ring-shaped liner under the first T-shaped joint liner and aligned with an opening in the branch pipe. The underground pipe repair device may include an annular spacer aligned with the opening in the branch pipe and being between the first T-shaped joint liner and the second ring-shaped liner. The annular spacer may include a radial step, and the second ring-shaped liner may be coupled to the base portion of the first T-shaped joint liner to retain the annular spacer.
