The original Dynamic Cone Penetrometer
(DCP) was developed in 1959 by the late S-20000
Professor George F. Sowers. The DCP uses
a 15 lb (6.8 kg) steel mass falling 20 in (50.8 cm) that strikes
the anvil to cause penetration of a 1.5 in (3.8 cm) diameter cone
(45° vertex angle) that has been seated in the bottom of a hand
augered hole. The blows required to drive the embedded cone
a depth of 1-3/4 in have been correlated by others to N values
derived from the Standard Penetration Test (SPT). Experience
has shown that the DCP can be used effectively in augered
holes to depths of 15 to 20 ft (4.6 to 6.1 m).

Heat treated cone, zinc plated components. The cone
can be replaced with a plated Drive Tube Assembly for collection
of 3 x 10 in (7.6 x 25.4 cm) tube samples in hand augered holes.

The S-205 Cone Penetrometer Test Set for 10-ft depth is simi-

As a related item, the Sleeved Drive Hammer, S-20000, provides
an alternative method of conducting the DCP Test. It is designed
to fit standard “E” drill rod extensions and the penetrometer point
assembly. There are no exterior impact zones on the sleeved
Drive Hammer sides. The 15-lb sleeved Drive Hammer unit is 4 - Removing the Sampler Tube.
