Sliding-Mass Dynamic Cone Penetrometer
DCP Hammer Kit.
Description
The Sliding Mass DCP consists of a 15-lb mass that drops 20-in to strike an anvil driving a 45° cone into the bottom of a hand augered borehole. The original version was first published in ASTM’s STP 399 and authored by the late Georgia Tech Professor Emeritus George Sowers. The device was developed to allow engineers an alternative method to model N values derived by the Standard Penetrations Test (ASTM D1586 ) where site conditions would not facilitate the use of normal drilling equipment.
Published correlations have been made between the number of blows for DCP to achieve 1¾-in penetration and standard N values for in-place and compacted soils common to the Southeast US. Users are encouraged to develop similar correlations for site specific or regional soils.
DCP set includes detailed instructions for use and published correlations.

DCP Shelby Head with Tube
By replacing the cone assembly with a thin walled (Shelby) tube head, the Drive Hammer Device can be used to drive and retrieve a 12-in long Shelby tube of in-place soil from the bottom of an augered borehole. Thin walled tubes have swaged ends in accordance with ASTM D1587.
