KR60 Rotary Drilling Rig for Bridge Foundation Construction in Southeast Asia
Client: International Infrastructure Contractor
Location: Vietnam
Project Duration: 8 months
Application: Bridge foundation piling for highway construction
A major infrastructure development project in Vietnam required the construction of a 1.2km highway bridge crossing a river delta. The project demanded the installation of 120 large-diameter bored piles with depths ranging from 25 to 35 meters. The challenging soil conditions, consisting of soft clay, dense sand layers, and occasional cobble formations, necessitated reliable and powerful rotary drilling rig equipment capable of maintaining productivity in variable ground conditions.
- Complex Geological Conditions: The project site featured mixed soil profiles with varying densities, requiring versatile piling equipment that could adapt to changing ground conditions without significant downtime.
- Tight Project Schedule: With a strict deadline tied to government infrastructure milestones, the contractor needed construction machinery that could deliver consistent performance and minimize operational delays.
- Remote Location Challenges: The bridge construction site was located in a relatively remote area with limited access to heavy equipment service centers, making reliability and ease of maintenance critical factors in equipment selection.
- Environmental Considerations: Working near waterways required foundation equipment with minimal environmental impact, particularly regarding noise pollution and soil disturbance.
After evaluating multiple options, the contractor selected APIE FOUNDATION EQUIPMENT (CHINA) LIMITED as their equipment supplier, choosing the KR60 Rotary Drilling Rig for this demanding project.
Key Equipment Features:
- Drilling Diameter: 600mm - 1200mm (adaptable to project requirements)
- Drilling Depth: Up to 20 meters
- Torque: 60 kN·m (powerful enough for dense soil layers)
- Engine Power: 86 kW (efficient fuel consumption)
- Total Weight: 20 tons (optimal stability for large-diameter piling)
The KR60 rotary piling rig offered several advantages that made it ideal for this project:
- Versatile Drilling Capability: The rig’s robust rotary system and adjustable parameters allowed efficient drilling through varying soil conditions without equipment changes.
- Advanced Control System: Precise control over drilling speed, torque, and feed pressure enabled operators to optimize performance for each specific soil layer.
- High Productivity: The efficient hydraulic system and well-designed drilling mechanism achieved average drilling speeds of 8-12 meters per hour in the project’s soil conditions.
- Reliability: Built with high-quality components and rigorous quality control, the KR60 demonstrated excellent reliability throughout the 8-month project, with minimal downtime.
Performance Metrics:
- Total Piles Completed: 120 piles (100% completion)
- Average Drilling Speed: 10.2 meters per hour
- Equipment Uptime: 96.5%
- Project Completion: On schedule, meeting all milestone deadlines
The KR60 rotary drilling rig successfully completed all 120 piles within the project timeline, with zero major equipment failures. The contractor reported a 15% improvement in productivity compared to similar projects using competing equipment, attributing this to the KR60’s efficient design and reliable performance.
