摘要： A system and method is provided for enhancing the working end of a hydrovac boom hose having a longitudinal axis and a perimeter disposed transversely to the axis, the working end configured to vacuum earthy material from a digsite along the axis. A plurality of high pressure nozzles are disposable in spaced relation along the perimeter of the working end, and configured to emit high pressure fluid towards the digsite to dislodge the earthy material. The nozzles are angularly actuatable to selectively emit the high pressure fluid along a range of angles relative to the longitudinal axis, and are rotationally actuatable to selectively emit the high pressure fluid from a range of locations along the perimeter of the working end. The angular and rotatable actuation is independent of movement of the working end and/or of movement of the hydrovac boom hose.

摘要： A ground drill system (10) has a drill string 14 which forms first and second mutually isolated fluid paths (16 and 18) respectively. The drill string (14) has an up hole end (20) coupled to a dual circulation rotation head (22) and a down hole end (24) which is coupled to a drilling tool (12). The drilling tool (12) is operated by the flow of fluid delivered through the first flow path (16). A second fluid outlet (26) is provided intermediate the up hole end (20) and the drilling tool (12). The outlet (26) is in fluid communication with the second fluid flow path (18) and located a constant or fixed distance from the drilling toll (2). The second fluid outlet (26) discharges a flushing fluid flowing through the flushing flow path (18) into a hole being drilled by the drilling system (10). The rotation head (22) provides torque to the drill string (14) and thus the drilling tool (12).
