The sampler consists of a thin walled steel tube whose lower end is shaped to form a cutting edge.
Shelby tubes and thin walled sampler.
Thin walled open tube samplers are designed for taking samples in soft and firm cohesive soils.
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.
The thin wall tube samplers and head assemblies manufactured at diedrich drill meet or exceed all steel requirements listed in the dcdma specifications.
The thin steel tube may be removed from the sampler to be used as a container to transport the sample minimising disturbance preserving moisture and reducing delays in the sampling procedure.
Thin walled shelby tube sample.
The shelby sampler is a thin walled soil sampling system.
Thin wall samplers shelby tubes thin walled samplers are designed to take undisturbed samples in cohesive type soils and clays.
Two factors which are essential for evaluating engineering properties.
Whether your needs require a 2 thru 5 thin wall 3 sst or 3 seamless shelby tube you can find it here.
However some disturbance is caused due to friction of the sample on the inside of the sample tube.
