On Thursday June 20, 2013, Rausch was invited to help the Borough of Chambersburg install their first QuickLock point repair sleeves. Rausch sent their experienced demonstration team to teach the Borough operators how to run the QuickLock system.
The first repair was performed in a 10″ clay line. The team set up the inspection truck downstream and sent in an inspection camera to locate and inspect the damages previously located by the Chambersburg operators.
Having approved the damage as appropriate for a QuickLock repair, the Rausch team proceeded to demonstrate how to assemble the EPDM rubber gasket and 316L stainless steel sleeve. Then they loaded the QuickLock sleeve onto the packer, which will be pushed into place by a TV camera in the pipe.
The Chambersburg Borough team blocked the flow of the line with a pipe plug at the next manhole. Then, they lowered an operator into the manhole to connect the QuickLock system with the transfer bar attached to the pipe inspection camera.
Once the system was in the line, the entire operation was controlled from the control room of the Rausch truck. The QuickLock packer was pushed into place over the spot damage in the line. An air compressor regulated the air pressure flow to the packer. The bladder of the packer expanded to lock the sleeve permanently into place. On each QuickLock sleeve, a one-way-ratchet gear mechanism runs along a saw-tooth channel as the sleeve expands. Once maximum compression was reached, the packer deflated and could pass through the installed QuickLock Sleeve.
