PIPE REPAIR
A pipe repair apparatus for repairing partially collapsed pipes. The pipe repair apparatus comprises: an actuation assembly comprising: a plurality of actuation arms; a plurality of hydraulic cylinders; and a plurality of hydraulic lines, wherein each hydraulic line in the plurality of hydraulic lines supplies hydraulic fluid to a respective hydraulic cylinder in the plurality of hydraulic cylinders, wherein each hydraulic cylinder in the plurality of hydraulic cylinders is configured to move a respective actuation arm in the plurality of actuation arms between a retracted configuration and an extended configuration to move a partially collapsed part of a partially collapsed pipe from a partially collapsed form to a non-collapsed form. The pipe repair apparatus comprises a control module configured to control each individual hydraulic line in the plurality of hydraulic lines such that each actuation arm in the plurality of actuation arms is actuated independently.
