Cone penetration test


 

CPT


    CPT provides data on soil strata, their homogeneity and thickness, presence of cavities and cracks in soil mass. Cone tip resistance and side friction parameters enable identification of soil type and evaluation of its physical and mechanical parameters.
   The cone is equipped with gages to measure cone tip resistance, side friction and inclination angle (x,y). Thanks to the digital data communication capability the impact of the cable and joints on measurements is minimized.    
  The probe connects with computer via USB drive. The software, installed in computer, registers the measured parameters, inputs them in a database and then outputs them as graphic profiles and computed soil parameters. 

Standards:  GOST 19912, ASTM   D 5778,  BS EN ISO 22476-1
