Static cone penetration test equipment, cone penetration test (CPT) is a field test method used to determine the geotechnical properties of soil. A cone-shaped probe is introduced into the soil layer at a constant speed while measuring the resistance at the cone tip and the resistance along the axis (friction resistance). The data obtained from the CPT is used to draw a continuous change curve of the soil layer profile, which is used to estimate the soil stratum, bearing capacity and other soil
