What Does Split Barrel Sampler Mean?
A split barrel sampler can be defined as a steel sampling tool used for obtaining soil samples from sub-surface soil formations. Split barrel samplers are used for a standard penetration test (SPT) of soil to obtain disturbed and undisturbed samples for laboratory testing.
The test provides an indication of the relative density of the granular deposit and its approximate shear strength. It can also be used for cohesive soils to determine its unconfined compressive strength.
Conducting soil tests are important to understand the sub-surface soil properties based on which pipelines and boreholes are designed, and trenchless installation methods are selected.
