Abstract
Description
Technical Field
[0001] This utility model relates to the field of static penetrometer technology, and in particular to a static penetrometer calibration device. Background Technology
[0002] The static cone penetrometer (PCP) is a widely used in-situ testing device in geotechnical engineering investigation. It assesses the mechanical properties and stratigraphic distribution of soil by measuring parameters such as cone tip resistance (qc), sidewall friction (fs), and pore water pressure (u). The accuracy of its measurement data directly affects engineering geological evaluation, foundation design, and construction safety. Therefore, the calibration of the PCP is crucial. Field tests require comparison with data from other penetrometers or boreholes. However, stratigraphic inhomogeneity and differences in human operation can introduce additional errors. The lack of a unified calibration benchmark and the current calibration process, which relies heavily on manual operation, are inefficient and susceptible to subjective interference, making it difficult to meet the needs of large-scale engineering testing. Therefore, we have redesigned a PCP calibration device. Utility Model Content
