Dynamic Probing Super Heavy – DPSH

Antonio Machado

The Dynamic Probing Super Heavy (DPSH) uses a hammer that delivers energy to a rod string by dropping a weight of 63.5kg from a height of 760mm. 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).
