Rock drilling and sampling

Core – Core sample

Core sampling.

Corer – Sampler

Cylindrical sampling tool with circular cross-section designed to obtain a sample or core, and used in a purpose-built borehole, either by punching (sinking, hammering or vibropercussion) or by rotation.

Technical drilling section – Drilling record

All information about the borehole (characteristics, execution details, water arrivals or losses, incidents, observations, etc.). ).

Sample – Sample

Sampling result.

Échantillon non-remanié – Undisturbed sample

A sample, taken under conditions that modify as little as possible the nature and condition of the soil, which, in the laboratory, under an appropriate stress path, provides results applicable to the prediction of in-situ strength, amplitude and rate of deformation.

Depending on the properties to be determined on the sample,...
