Abstract
A seismic energy source which incorporates multiple augers and a rotary mechanism therefor mounted on a vehicle, the auger incorporating an internally situated seismic shock wave source which creates shock waves passing through a window in the auger into the soil. The shock wave source incorporates a chamber which stores compressed air and a valve mechanism which releases the air sharply for a short interval to create a shock wave in the soil.
Claims7
An apparatus for creating a seismic shock wave to be propogated through the earth in seismic investigations comprising:
- an auger means having:
- a helical flite thereon which is adapted to enter the earth on rotation;
- an elongate body having means for receiving at least two pneumatically operable sonic shock wave creating means, said sonic means cooperative with said auger means and having an opening from said body to the exterior of said body for directing sonic energy into the earth below the earth's surface.
