Project Overview:
A bridge construction project in a geologically complex region required drilling through an unpredictable overburden containing layers of sand, gravel, and cobbles to reach stable bedrock for pile foundations. Conventional rotary or impact drills risked getting stuck or causing hole collapse in such conditions.
Customer's Core Challenges:
Unstable Formations: Risk of borehole collapse in loose sand and gravel layers.
Obstacles: Presence of cobbles and boulders that could damage standard drill bits or halt progress.
Need for Reliability: The remote location made equipment downtime and lengthy repairs extremely costly.
APIE's ROTART DRILLing RIG Solution:
We provided a heavy-duty ROTART DRILLing RIG configured with a dual-power head system and a suite of specialized drill bits. This tailored solution offered unmatched versatility and power.
Advanced Casing Advancement: The rig's lower rotary drive independently rotated a protective casing with a carbide-studded shoe, cutting through the unstable overburden (sand, gravel, cobbles) and stabilizing the borehole walls in real-time.
Specialized Drill Tooling: The upper rotary drive operated the internal drill string, which was fitted with a rugged rock roller bit to efficiently break through the embedded boulders and the final bedrock layer.
Built for Durability: The rig was equipped with an extreme-torque planetary gearbox, designed to handle the shock loads from hitting hard rock and provide consistent power under high stress, ensuring reliability in harsh conditions.
Results and Value Delivered:
Uninterrupted Progress: The rig successfully drilled all foundation piles without a single major incident of hole collapse or equipment failure due to geology.
Adaptive Efficiency: The ability to switch drilling strategies and tooling on the same rig platform minimized downtime and maximized productivity across changing layers.
Project Security: The contractor completed the critical foundation phase on budget, avoiding the massive cost overruns typically associated with complex geotechnical surprises.
Client Testimonial:
"We were hesitant about the site's geology, but APIE's technical team proposed a rig configuration that handled every challenge we encountered. The dual rotary system and the right drill bits made the impossible, possible. Their rig's robustness was impressive." – Chief Engineer, International Bridge Consortium.
