Product Overview
Model: YTZ Series | Category: Foundation Construction Equipment
The Auger Drilling Rig is a long-spiral drilling rig designed for continuous flight auger (CFA) pile construction. Its full-hydraulic drive and 360-degree rotation enable efficient, low-noise piling in urban environments. The rig excels at bored cast-in-place piles for residential buildings, municipal bridges, and foundation reinforcement works, particularly in loose soil, sand, and sandy clay layers.

Performance Feature
1. Continuous Flight Auger Technology
The Auger Drilling Rig uses a long continuous flight auger to drill and simultaneously convey soil to the surface. This method produces smooth, clean boreholes without slurry, making it faster and more environmentally friendly than conventional cast-in-place pile methods.
2. Full-Hydraulic Drive
All functions including rotation, crowd, winch, and crowd are hydraulically controlled for smooth and responsive operation. The hydraulic system provides overload protection and precise speed control for different soil types.
3. Low Noise and Vibration
Compared to impact hammers and vibratory piles, the auger rig operates with significantly lower noise and vibration levels. This makes it suitable for urban construction near residential areas, hospitals, and existing structures.
4. Efficient Pile Construction
The rig achieves rapid pile installation with minimal displacement. Concrete can be tremied through the auger stem while withdrawing, creating a high-quality bored pile with good bearing capacity in a single continuous operation.

What pile diameters can the auger drilling rig produce?
The Auger Drilling Rig typically produces bored piles ranging from 400 mm to 800 mm in diameter, with depths up to 26-30 meters. This covers the majority of cast-in-place pile applications for buildings, bridges, and infrastructure.
What is continuous flight auger (CFA) piling?
CFA piling uses a long helical auger drilled to design depth, after which concrete is pumped through the hollow stem while the auger is withdrawn. This creates a smooth, high-quality pile with minimal soil displacement and no temporary casing needed.
What ground conditions are suitable?
Auger drilling works best in cohesive soils, sand, silt, and loose gravel. It is less suitable for very hard rock or dense cobble layers that would require different drilling tools.
How does CFA compare to bored pile with casing?
CFA piling is faster, cleaner, and produces less soil spoil than conventional cased bored piles. It also avoids the noise and vibration of impact driving. However, it has depth and diameter limitations compared to large rotary bored piles.
What is the concrete placement process?
After drilling to design depth, concrete is pumped through the hollow auger stem under pressure. As the auger is slowly withdrawn, concrete fills the borehole, displacing the soil cuttings upward. Reinforcement cages are inserted after concrete placement.
Does Yutong export to my country?
Yutong Heavy Industries exports construction machinery to over 60 countries across Asia, Africa, the Middle East, South America, and Eastern Europe. We have established dealer and service networks in major markets. Contact us to confirm availability in your region.
What warranty does Yutong offer?
Standard warranty coverage applies for 12 months from delivery or an agreed operating hour limit, whichever comes first. Extended warranty options are available. The warranty covers manufacturing defects in materials and workmanship.
