Conventional Conveyor Flight Auger Drilling for Geotechnical soil
Sampling
Conventional Conveyor Flight Augers:
With the addition of a cutter head, conveyor flight augers are
commonly used for drilling to 100 ft. (30.5 m.) depths where soil
cover permits. Obviously, the sizes are many, but the most commonly
used sizes are listed as standard. Cutter heads generally are
somewhat larger in diameter than the conveyor flight, to provide
clearance for the cuttings to work easily to the surface. Optional
features such as "hard facing" of the augers can be provided for
added tool life, when drilling abrasive formations. Flight
connector pins are the drive pin type and are simple, but rugged.
Conveyor flight auger lengths vary, but 3 ft. (0.9144 m.) and 5 ft.
(1.524 m.) are the most popular lengths. Consult the chart for
pitch and standard connections commonly used for auger boring
applications. All flight augers are timed or synchronized, and
there are no gaps in the flight between auger sections.
Note: When drilling conditions are difficult, augers may be "hard
faced" the full length, or 6 inches on each end. When desired
simply specify, H.F. "full length" or "each end".
Note: Augers are furnished with standard hexagonal shank or socket
connections.
