Product Description
C099 Soil Standard Penetration test SPT with split spoon
It is used to determine the bearing capacity of all kinds of soil, find out uniformity coefficient of soil In the horizontal and vertical directions, confirm location of Pile foundation bearing layer and Estimate the bearing capacity of single pile.
Using hammer energy, infiltrate special Cone probe into soil. We can distinguish engineering properties of soil according to the complexity of infiltration.
evaluation index use blow counts when Injection to some depth. It is main way to test Coarse grained soil.
