ABSTRACT:
A vibratory core drill apparatus for the recovery of soil or sediment core samples. The samples are collected within a rapidly vibrating sample tube which is driven into the ground by the apparatus. The apparatus comprises a drill stand, vibratory drive for imparting a vibratory motion to the sample tubes, coupling for coupling the sample tubes to the vibratory drive, support for supporting and restraining the coupling and vibratory drive, a carriage assembly for mounting the support to the drill stand in sliding up and down fashion, and carriage drive for lifting or lowering the carriage assembly. The invention permits the rapid recovery of representative soil or sediment samples at depths of up to 20 meters without the periodic disassembly of the invention during the drilling operation.
