Reverse Circulation Core Drill Rig for Soil Investigation
This specialized Reverse Circulation (RC) core drill rig is engineered for high-efficiencysoil and subsurface investigation, providing reliable sampling for geotechnical studies,environmental assessments, and construction planning. Designed to deliver undisturbed,
contamination-free core samples from various soil layers, it ensures accurate data collection
for analyzing soil composition, stability, and stratification.The rig employs a reverse circulation system using dual-wall drill rods, where air or fluid is
pumped downward through the outer annulus, enabling rapid penetration while soil and
core samples are cleanly retrieved through the inner tube. This sealed process minimizes
external contamination and preserves the original structure of soft, loose, or layered
soils—critical for precise laboratory testing and engineering evaluations.
Built with a modular and compact structure, the rig offers easy transport and quick setup
in constrained or remote areas.
