Abstract
A system and method to excavate using a pneumatic shock wave includes a supply of pressurized fluid, a suction wand, and an air line in communication with the supply of pressurized fluid. A portion of the air line is integrated within the suction wand. The system also includes a dump valve interposed between the supply of pressurized fluid and the portion of the air line integrated within the suction wand. The dump valve is configured to rapidly discharge a pulse of the pressurized fluid out an open end of the air line to generate a shock wave at a distal end of the suction wand to fracture and dislodge soil so that the suction wand can excavate the soil.
