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 And 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
Principle
* It has no radiation, nuclear contamination, and is cheap, small and easy to carry in the field.
* It is used in domestic industrial and civil construction, highway, railway, road and bridge, municipal drainage, oil pipeline, water conservancy, dam construction, dike, irrigation canal, reservoir construction, airport runway engineering.
* Penetration method a group of tests up to 15-20 minutes, high efficiency, fast, productivity liberation.
