Abstract

A modular compaction boring device. The boring device comprises a compaction boring head which creates a borehole through a subsurface by operation of a thruster and a rear and forward anchor. Extension of the thruster while the rear anchors are engaged move the boring head forward. Retraction of the thruster while the forward anchors are engaged brings the rear anchors forward for an addition stroke. A steering geometry in the boring head and rotation of the boring head allow steering of the boring device. Steering, thrust, and anchors may be controlled remotely through an umbilical cable pulled through the borehole by the boring device.
