Abstract
The present invention is a lance for removing dirt or other substances from an underground hole, by the use of air and water under high pressure. The water is used as an abrading material or lance to loosen dirt in a hole or to pick or chip off substances which are attached to a pipe. A limited amount of water is used during the operation of the apparatus, to prevent the formation of wet mud.
