kärnborrsträngen
Kärnborrsträngen refers to a specific type of drilling string used in certain drilling operations, particularly in geological or geotechnical investigations. It is designed to extract a cylindrical core sample from the subsurface. This core sample allows for detailed analysis of rock formations, soil layers, and the presence of any minerals or groundwater. The term "kärnborrsträngen" is of Swedish origin, directly translating to "core drill string."
The composition of a kärnborrsträngen typically includes a drill bit, drill rods, and often a core barrel.
Kärnborrsträngen is employed in various applications such as environmental site assessments, mineral exploration, and foundation studies
