Rotary drilling rig construction case

A client in Southeast Asia required a foundation project for a large commercial complex, including bored pile construction in complex soil layers and high groundwater levels. The construction site had limited space, and the project demanded high drilling efficiency, stable hole formation stability, and strict adherence to foundation quality standards.

The rotary drilling rig we selected performed exceptionally well due to its excellent adaptability. It excelled in hard soil, weathered rocks, and high water levels, offering stable torque, precise depth control, and good maneuverability in confined construction areas.

The rig first completed on-site positioning and alignment of the pile, followed by casing installation, rotary drilling, soil removal, and hole wall cleaning. During the construction process, the rig maintained a stable drilling speed and high torque output, effectively penetrating mixed soil layers and weathered rock layers. Compared to traditional piling methods, rotary drilling significantly reduced noise and vibration, making it particularly suitable for urban construction environments.

Thanks to its deep drilling rig foundation capabilities and efficient cycle time, this equipment completed multiple pile positions ahead of schedule. At the same time, it significantly reduced rework and improved overall foundation quality, meeting strict requirements for verticality, hole diameter, and pile depth.

This project successfully completed the required bored pile foundation engineering, with stable hole formation, high construction safety, and good environmental performance. The client achieved accelerated progress, reduced construction risks, and reliable foundation quality.

This case demonstrates that our refurbished rotary drilling rig can meet the complex foundation construction requirements in urban areas, with excellent cost-effectiveness and engineering reliability.
