Petrol Standard Penetration Test Apparatus

استاندارد: ASTM D1586, ISIRI 12305-03

General Discriptions Download Manual

The Standard Penetration test (SPT) is a common in situ testing method used to determine the geotechnical engineering properties of subsurface soils. It is a simple and inexpensive test to estimate the relative density of soils and approximate shear strength parameters.
Standard Penetration Test, SPT, involves driving a standard thick-walled sample tube into the ground at the bottom of a borehole by blows from a slide hammer with standard weight and falling distance. The weight of the hammer is 63.5 kg. This hammer falls from a height of 76 cm base on standard.
This apparatus consists of:

  • Portable structure
  • 63 kg Standard hammer
  • CPT head
  • SPT head
  • 5 hp petrol motor
  • 20 m rope
  • Heavy duty auger extension rod
