Abstract : The repetitive-explosion device for soil displacement (REDSOD) utilizes the energy generated within a chamber by the combustion of compressed air and hydrocarbon fuel to displace and move material. An integral wedge-shaped shoe with a large exhaust opening in its top surface is pushed into a soil overburden at depths up to 5 or more feet by a transporting vehicle. When the combustion chamber pressure has reached a maximum value hot, high-pressure gases are released through an exhaust opening under the soil overburden. The soil is disaggregated and displaced up and out of the excavation. Deflectors can turn the direction of the soil's trajectory to deliver it to one side of the excavation. A greatly increased productivity per unit of equipment is possible over conventional earth-moving equipment. (Author)
