The paper discusses the feasibility of combining compaction and excavation processes in hole making. The continuous loop of hole-making and soil removal from hole pipe by compressed air return flow is proposed. Usability of an air hammer drill with elastic valve in the air distribution system in capacity of a drifter motor is examined. Using a physical dimension model with piston 4 kg in weight, the author refines energy and frequency performance of the pulse generator given the backpressure in the exhaust chamber. The experimental curves of the percussion capacity parameters are obtained.
