Collect samples without disturbing the target ground! Sampling using a borehole.
When designing structures and predicting ground deformation, it is necessary to confirm the strength characteristics, deformation characteristics, and consolidation characteristics of the ground. To verify these, there are methods to conduct investigations in situ, but it is common practice to collect undisturbed samples from the ground under consideration and perform appropriate laboratory soil tests. "Tube sampling" is one method of collecting undisturbed samples by lowering a sampler to the bottom of a borehole and either pressing it in or rotating it to obtain the sample. [Types of Samplers (Partial)] ■ Fixed piston type thin-wall sampler ・Hydraulic type / Extension rod type ■ Rotary double-tube sampler ■ Rotary triple-tube sampler ■ Rotary sleeve-integrated double-tube sampler *For more details, please refer to the PDF document or feel free to contact us.
