Rotary drilling rig standardized construction covers four key stages: installation preparation, core construction, quality control, and completion & site clearance. It ensures precise control (hole position deviation ≤5cm, sediment thickness ≤5cm) via site leveling, parameter adaptation, real-time monitoring and node acceptance. Strict implementation of this process is the key guarantee for efficient, safe and high-quality construction. Read More

Intelligent upgrading reshapes rotary drilling rig construction, boosting efficiency via core technologies. Its intelligent drilling control system uses multi-sensor fusion for real-time optimal parameter matching, improving efficiency by 40% vs manual operation. Remote monitoring and fault early warning (via cloud and big data) prevents failures to ensure continuous work. Collaborative operation system enables multi-equipment scheduling and data sharing, cutting manual input by 50%. Cases show intelligent rigs shorten single pile time by 37.5% and overall efficiency by 35%-40%. Beyond tech upgrade, it innovates construction concepts. Future with 5G and AI, full-domain collaboration and virtual construction will empower infrastructure engineering. Read More

For the construction of 126 pile foundations of the approach bridge of a river-crossing bridge, the Sany SR235-C10 rotary drilling rig was selected as the main equipment to solve the problems of complex geology and high groundwater level.
By adjusting parameters to adapt to different soil layers, the drilling rig increased the efficiency by nearly 3 times. 126 pile foundations were completed in 102 days, shortening the construction period by 15% and reducing the cost by 12% compared with the plan.
Finally, the proportion of Class I piles reached 98%, which confirms the efficiency and reliability of the rotary drilling rig in bridge pile foundation construction and provides a reference for similar projects. Read More
