ABSTRACT:
The present invention is a high velocity pneumatic and water device for excavating a work area. The device comprises a "T" shaped tubular body that is connected to an external source of high velocity air and water mix. At the top end of the device exists a valve and regulator assembly for individually adjustably controlling the amount of air and water which is delivered to the ports of three separate manifolds contained within the device. Through this adjustable control the device can deliver varying amounts of motive force to a surface and thereby be used to excavate a wide range of materials.
