SURFACE SOIL SAMPLER

SURFACE SOIL SAMPLER

CODE : T058

• The Surface Soil Sampler is used to determine the in-place density of soils using the drive-cylinder method, providing accurate measurements essential for geotechnical evaluations and construction quality control.
• This apparatus is suitable for soils that do not contain significant amounts of particles larger than 4.75 mm (3/16 inch) and can be readily retained within the sampling cylinder, ensuring the integrity of the specimen during extraction.
• Common applications include assessing the compaction quality of structural fills, highway embankments, and earth dams, where precise in-situ density measurements are critical for structural stability.
• The sampler comprises a thin-walled cylindrical tube driven into the soil to extract an undisturbed sample, which is then used to calculate the soil's density based on its mass and volume.
• To ensure representative sampling, the drive cylinder volumes are designed to be as large as practical, with a minimum volume of 850 cm³ (0.030 ft³), aligning with standard testing requirements.
