Detailed Solution
Download Solution PDFExplanation:
- A thin-walled sampler is used for obtaining an undisturbed sample.
- Shelby tube samplers are thin-walled, hollow steel tubes, which are driven Into the ground to extract a relatively undisturbed soil sample for use in laboratory tests used to determine density, permeability, compressibility, and strength.
- Piston samplers are thin-walled tube samplers, which are also used for collecting undisturbed samples in soft soil.
Additional InformationUndisturbed sample:
- An undisturbed sample is that in which the natural structure and properties remain preserved.
- These samples are used in size distribution, Atterberg's limits, consolidation parameter, coefficient of permeability, shear strength parameter.
Disturbed sample:
- A disturbed sample is that in which the natural structure of soils get partly of fully modified and destroyed.
- A thick-walled sampler is used for obtaining disturbed but representative samples.
