Abstract
A horizontal direction drilling system comprises a power pack coupled to a source of compressed air and a water reservoir and forms a mixture of compressed air, water, and oil. The horizontal direction drilling system further comprises a steerable horizontal drill. The steerable horizontal drill includes an air powered reciprocating hammer, and a drill head. The steerable horizontal drill receives the mixture to power the reciprocating hammer. The drill head includes a drill face and the mixture exits the steerable horizontal drill through the drill face.
Claims20
A horizontal direction drilling system comprising
- a power pack coupled to a source of compressed air and a water reservoir, the power pack including (i) a controller, (ii) an air flow valve coupled to the controller and operable to control the flow of compressed air from the source of compressed air, (iii) an oiler driven by compressed air, the oiler operable to inject a predetermine quantity of lubricant into the flow of compressed air, and (iv) a pump driven by compressed air, the pump operable to inject a quantity of water from the water reservoir into the flow of compressed air such that the air, oil, and water form a mixture, wherein the controller is operable to vary the flow of compressed air through the power pack, and
- a steerable horizontal drill including an air powered reciprocating hammer, and a drill head, the steerable horizontal drill receiving the mixture to power the reciprocating hammer, wherein the drill head includes a drill face and the mixture exits the steerable horizontal drill through the drill face.
A power pack for powering a horizontal drill comprising
- a controller,
- an air flow valve coupled to the controller and coupled to a source of compressed, the air flow valve movable between two positions to control the flow of compressed air,
- an air driven oiler injecting a predefined quantity of lubricant into the flow of compressed air, and
- an air driven pump injecting a predefined quantity of water into the flow of compressed air.
A steerable horizontal drill comprising
- a back body,
- an air powered reciprocating hammer, and
- a drill head including an offset drill face, the drill head moved by the air powered reciprocating hammer to work the ground to thereby form a bore.
