Product Description
Aim: it is a method to acquire representative soil samples to distinguish the soil of other tests, and acquire obstruction that the soil Penetration resistance to sample collector.
Standard penetration test aim: from the measured standard penetration number of hammer, judge Sandy soil compaction degree or Consistency of cohesive soil, in order to determine allowable bearing capacity of subsoil, evaluate Vibration liquefaction potential of sandy soil, estimate bearing capacity of single pile, confirm soil profile and disturbed soil sample to test.
