The Shelby tube sampler (88.9 mm), developed by Technidrill, is a go-to solution for collecting undisturbed samples. It is especially effective in plastic or cohesive soils such as clays, silts, and soft deposits. Engineered to meet the demands of geotechnical investigations, this equipment maintains the soil’s natural structure—an essential condition for accurate laboratory analyses and mechanical behavior testing.
Sampling tube designed to minimize disturbance
The Shelby tube sampler 88.9 mm consists of a thin-walled cylindrical tube manufactured with high precision to limit material deformation during sampling.
A sharpened cutting edge enables smooth soil penetration, reducing stress and the risk of remolding.
The integrated check valve secures sample retention during extraction, preserving the integrity and representativeness of the collected material.
With its 88.9 mm outer diameter, the Shelby tube sampler is ideal for projects requiring a smaller sample volume without compromising in-situ characteristics. Its robust design and compatibility with standard drilling equipment make it a versatile, durable choice for field teams.
Applications of the Shelby tube sampler 88.9 mm
- Geotechnical site investigations in urban, industrial, or natural settings
- Environmental sampling for physico-chemical analyses
- Laboratory tests on fine soils: compressibility, permeability, direct shear, and triaxial tests
- Quality control for shallow and deep foundations
- Condition monitoring before and after construction
This Technidrill sampling system delivers dependable results, even in deformation-sensitive soils, ensuring the level of precision required by geotechnical engineers and accredited laboratories.
