Pengeboran Inti Rotary

Rotary core drilling is a critical site investigation technique within the auxiliary works phase of deep foundation projects, enabling geotechnical engineers to obtain high-quality undisturbed soil and rock samples from various depths. This drilling method uses a rotating cutting bit—typically a core barrel with diamond or carbide cutting edges—to penetrate through layers of soil, clay, silt, sand, gravel, and bedrock while preserving the structural integrity of the recovered core samples. Unlike percussion or auger drilling, rotary core drilling maintains precise control over drilling speed, pressure, and fluid circulation, making it the preferred method for detailed stratigraphic analysis and geotechnical assessment prior to deep foundation design and installation.
