Dynamic Cone Penetrometer

The Dynamic Cone Penetrometer 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 augured 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 augured 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-augured holes.

The S-200 Dynamic Cone Penetrometer and Auger Test Set for 10 ft depth includes:

• Standard Sliding Drive Hammer Assembly
• Cone Penetrometer Point with 1-ft Adaptor Rod
• 30-in. “E” Drill Rods
• Standard Auger Head
• 36-in. Auger Extensions
• Tee Handle and Operating Instructions

S-205 Cone Penetrometer Test Set

• For 10 ft. depth
• Similar to the S-200 set
• Does not include auger items

Sleeve Drive Hammer

As a related item, the Sleeved Drive Hammer, S-20000, has been designed to provide a safe means of conducting the DCP Test in accordance with ASTM STP-399, the most widely accepted portable method for evaluating strength and density of soil, in situ. It is designed to fit standard “E” drill rod extensions and is compatible with existing Dynamic Cone Penetrometer units. There are no exterior impact zones on the Sleeved Drive Hammer sides. The 15-pound Sleeved Drive Hammer unit is compact, easy to transport, is zinc-plated for protection against corrosion and is capable of being disassembled by the user for periodic inspection and cleaning. Patent Pending.
