What Does Dry Boring Mean?
Dry boring is auger boring that does not use drilling fluids to remove spoil. It uses a specialized auger system called a dry boring machine, which operates within a bore pit the length of one pipe segment plus the length of the machine. As the machine creates the bore, the auger bit pulls the pipe into the newly created bore.
The auger also spools the spoil from the bore as it turns, much like a drill bit removing wood or metal from a hole it's creating.
The spoil pile is usually removed from the bore pit during the process.
