ABSTRACT:
An apparatus for forcing a member or device, such as a sample tube or seismic or geological instrument, through a material such as soil along a selected line of action. The apparatus includes a derrick with first and second plates mounted thereto, the second plate having a locking dog extending through a hole therein for engaging the material, and the first plate being provided with a hydraulic cylinder or other device for forcing the member through the material. The first plate is also provided with an extruder head for releasably mounting the sample-containing sample tube thereto, and the hydraulic cylinder is provided with a plunger releasably mounted to the ram thereof for extruding the sample from the sample tube. The locking dog positively engages the material to provide an apparatus for transmitting the reactive forces resulting from forcing the member through the material to the material. The outer surface of the locking dog is shaped to approximate the shape of the hole and the locking dog is provided with a radially extensible member for engaging a discontinuity or groove in the wall of the hole to transmit the reactive force exerted by the force exerting apparatus to the material. Also provided is an apparatus for removing material from a wall of the hole through the material and a method of sampling the material under a strata.
