Universal type penetrometer is based on the geotechnical experiment: the penetration of soil and the dry density of soil, the relationship between the relationship between the penetration and water content of soil and the relationship between soil water volume and compactness, through a lot of penetration and ring cutting parallel contrast test, establish the regression equation, the rate of penetration resistance between the dry density and the related data sheet.
By measuring the penetration resistance and looking up the table, the dry density can be quickly obtained, and then the compaction coefficient can be quickly calculated. Two, main technical parameters
