Portable Hydraulic Core Drilling Rig with 200m Drilling Depth and High Efficiency for Tunnel Projects

The portable underground tunnel core drill is the embodiment of tactical geotechnical intelligence. Its performance—defined by compactness, agility, and precision—provides a decisive operational advantage: the ability to obtain high-fidelity ground truth data anywhere, anytime during tunnel construction. This translates directly into enhanced adaptive management, reduced stand-by time, lower costs, and ultimately, a significant de-risking of the tunneling process in real-time.

The portable rig transforms geotechnical investigation from a major logistical operation into an agile, integrated site task, offering distinct advantages for tunnel projects.

• Unmatched Mobility & Minimal Interference: Can be rapidly moved between multiple drill sites within a tunnel without disrupting major operations like mucking, lining, or TBM advancement. It allows for "just-in-time" probing of specific zones of concern.
• Rapid Response to Unforeseen Conditions: When a tunnel face encounters unexpected geology (e.g., a fracture zone or change in rock quality), this rig can be deployed within hours to drill short probe holes and retrieve core samples, enabling immediate, data-driven decisions on support adjustments.
• Significant Cost Efficiency:
  • Lower Capital & Logistics Cost: Much less expensive to purchase and transport than large dedicated drill rigs.
  • Reduced Operational Cost: Requires a smaller crew (2-3 personnel) and minimal supporting infrastructure (e.g., no large crane or extensive pad preparation).
  • High Utilization: Its mobility allows it to serve multiple tunnel drives or projects, maximizing return on investment.
• Enhanced Safety & Operational Flexibility: Allows for precise, targeted drilling from safe, stable locations (e.g., from a secured platform or behind supported ground). Enables critical investigations like checking rock bolt embedment depth, verifying lining bedrock quality, or sampling behind the tunnel wall without major downtime.
• Complementary Role in a Comprehensive Strategy: Perfectly complements a long-range probe drilling program. While a larger rig drills the primary deep (e.g., 200m) probe holes, portable rigs perform follow-up verification holes, shorter lateral probes, and geotechnical spot checks with minimal schedule impact.
