tip resistance qd (MPa) or counts every 10 or 20 cm (N10 or N20)

• Data processing software

Operating For compaction control, the measurement of the driving depth in mm per strike is compared to a database based on the type of soil (soil classification), its water content and the required compaction quality (%OPN or OPM). Anomalies calculation is done automatically with the embedded software. For soil investigation, the penetrogram can be drawn according to the dynamic resistance (MPa) and the number of blows every 10 or 20 cm (N10 or N20). A geological cross-section (database available) can be associated with the penetrogram.

GRIZZLY® DPSH

Penetrogram Results Example

GRIZZLY® : easy to use and efficient A rod extractor is integrated into the hammer with a powerful hydraulic extraction strength of 11 tons. Setup is fast setup thanks to the pole hydraulic tilting adjustment system (both vertically and horizontally). The GRIZZLY® can access any kind of terrain thanks to the tracked prime mover. It has great stability on hilly terrains because of its low centre of gravity. The use of GRIZZLY® complies with several standards and regulatory requirements : NF P94-063 – Compaction quality control - Constant energy dynamic penetrometer method. NF P94-115 – Soil investigation and trials – Type B sounding with a dynamic cone penetrometer. NF EN ISO 22476-2 – Soil investigation - geotechnical trials – dynamic penetration trials – DPSH- B Options Torque wrench to control excessive lateral friction between soil and the rod. Drilling tool with Auger (diameter 63 mm) for soil investigation at low depth. SPT core sampler (NF P94-116 standard)
