TRIC Training Log: 06-05-04

Client: ARS Rescue Rooter, Memphis, TN

Job: Residence, under driveway

Pull: 45’ / 4” / SDR17


For Sale: A grand old home in the historic district of Memphis. Sewer needs work.


The connection: Under the driveway, joining the cottage adjacent to the garage (behind trees) with the main house.


Saving the surface: The connection at the house is roughly 8’ deep; all excavation is done in the planted areas.


Garden view. Note excavator to the right.


Entry point: PVC irrigation pipe can be cut. Unused steel pipe protruding above surface at edge of hole will also be removed.


Facing.


Keep blades moving: Watch for full ribbons of trim from both faces.


Clean and check: Remove shaved material from fusing area.


Before heating: Double check mating surfaces, and remove any debris from edges with a clean cloth.


Heating the pipe: Make firm, even contact with heating iron, then use neutral pressure.


The melt: This varies according to pipe size and rating; for SDR 17 in smaller sizes (3”, 4”, 6”) look for a melt of 1/8” or slightly less.


Entry: Breaking out the old pipe. Note minimal excavation.


Entry: Cutting away unused protruding pipe in “drag path” (left).


Feeding the cable: In many cases, it is not necessary to use the duct rod to pull cable through the line. Here the pull is downhill, relatively short, and steep.


Positioning the new pipe: Making the approach as direct as possible.


Attaching hydraulic hoses.


Pulling end: Cribbing the wall to provide even support for the resistance plate.


Ready for tension: Keep pressure gauge visible.


Feeding the pipe: It’s important to give the bursting head a good start.


Well underway: After a good entry, pipe often needs little attention.


End of the pull: Removing the cotter pin from the clevis bolt.


“Bumping”: Fuse enough pipe to have this option when the pull is done.


Photo Op: Hands-on Management!


Ready to connect: When possible, give plenty of cutoff length behind the head. (Note brass water supply line, which was easily avoided with the TRIC system.)
