Pipe Eating

Definition - What does Pipe Eating mean?

Pipe eating is a replacement process similar to pipe jacking, where powerful hydraulic jacks force a pipeline into a bore as the bore is created. Also known as pipe replacing, in the pipe eating process, a drill destroys the pipe and removes its fragments while inserting a new pipeline or sewer – of the same size or large – in the original bore.

Trenchlesspedia explains Pipe Eating

Pipe eating is similar to pipe bursting and isn't as unappetizing as it sounds. The old pipe remains in the ground where it's ground into small pieces by drill while a hydraulic jack forcing a new pipe into place, The flow of drilling fluid from the BHA (bottom hole assembly) carries the fragments of the old pipe away while the drill and jack continue to ram the new -- and possibly larger -- pipe into place.
