Product Description

【 Product Application 】

The general type penetration instrument is also called the filling compactness tester or the foundation bearing capacity tester, which is used to test the dry density and uniformity of backfill soil, which can save and replace the ring knife method of sand and water filling method in the construction site to check the filling quality in a large and all-round way, reduce the workload of geotechnical testing, and shorten the construction period. It is suitable for the construction unit's layered rolling and layered inspection. It is also suitable for sampling any layer of quality inspection and supervision companies, and is also suitable for on-site teaching and learning in colleges and universities to do geotechnical experiments.

Based on the correlation between penetration degree and dry density of soil, the relationship between penetration degree and water content of soil, and the relationship between water content and density of soil in geotechnical tests, the general type penetration instrument has established a regression equation through a large number of parallel comparison tests of penetration degree and ring knife method to determine the correlation data table between penetration resistance and dry density of excavated soil. By measuring the penetration resistance and checking the table, the dry density can be obtained quickly, and then the compaction coefficient can be calculated quickly.
