Geotechnical (Soil) Testing Equipment-Product-Aihua

Using a 63.5 kg split hammer with a free fall distance of 76 cm, drive the split sampler 30 cm into the bottom soil layer of the borehole after the bottom has been cleaned. Record the number of blows required to achieve penetration and use this count to assess the natural density of the soil.

63.5 kg Heavy Dynamic Penetrometer

The cone penetration test utilizes a specified amount of hammer energy to drive a cone of a fixed diameter into the soil. By measuring the resistance encountered as the cone is driven into the ground, changes in soil layers can be identified, soil layers can be mechanically stratified, and the physical and mechanical properties of the soil layers can be determined, enabling an engineering geological assessment of the foundation soil. Typically, the resistance of the soil is expressed in terms of the number of blows required to advance the cone a given distance into the ground. This test must comply with the standards outlined in the “Code for Exploration of Rock Engineering” (GB 50021–94).
