  • High-efficiency earth boring system
    Patent number: 5246079
    Abstract: A horizontal earth boring method and system which uses hydraulic linear and rotary drives in combination with a compressed air flow to the drilling element. The compressed air flow is utilized in addition to continuously flush the bored hole which greatly increases drilling efficiency and lowers power requirements. A smaller hydraulic drive unit is thereby required and the overall system can be controlled from an out-of-ditch location.
