In the field of modern construction and infrastructure, pile foundation is a key component to ensure the stability and safety of the structure. Choosing the right pile foundation construction equipment is essential to improve project efficiency and reduce costs. Among the many pile foundation processes, continuous spiral drilling is particularly suitable for urban centers, adjacent to existing buildings or areas with unstable geological conditions, due to its fast construction speed, low noise, and vibration. The YG CFA piling rig is a heavy-duty pile-driving machine based on a crawler chassis. It has excellent maneuverability and stability and is equipped with an intuitive control panel and real-time monitoring system.

YG CFA Piling Rig Brings Many Advantages to Your Pile Foundation Project:
- High construction efficiency: The continuous operation process reduces the idle time, the single pile construction speed is fast, and it is suitable for large projects.
- Reliable pile body quality: Concrete is continuously injected from the bottom through the hollow drill rod, with a high filling degree, avoiding collapse and segregation, and good pile body integrity.
- Strong adaptability: It is suitable for a variety of geological conditions, such as silt, clay, sand, fill, etc., and is particularly good at handling unstable soil layers.
- Environmentally friendly: The noise and vibration generated during the construction process are much lower than hammer piles or vibrating crushed stone piles, and have little impact on the surrounding environment and existing buildings.
- Cost saving: High efficiency shortens the construction period, reduces labor input, and does not require wall protection or mud circulation system (under certain conditions), reducing the overall construction cost.
- High safety: The high degree of automation reduces dangerous links such as high-altitude operations and manual casing.
Therefore, whether considering construction speed, pile body quality, environmental impact, or economic benefits, the YG CFA piling rig can provide excellent solutions.
How to Choose a CFA Pile Drilling Rig That Suits You?
- Clarify the project requirements: Small construction projects have relatively low requirements for drilling rigs, while large bridge or high-rise building projects have high requirements for drilling depth and load-bearing capacity. For example, the construction of high-rise office buildings usually requires the maximum drilling depth of the drilling rig to reach 30-50 meters or more to ensure a stable foundation; for general bridge projects, depending on the scale of the bridge and geological conditions, the drilling depth may range from 20-60 meters to ensure a solid foundation for the bridge.
- Consider geological conditions: Bridge construction in mountainous areas, with many rocks underground, requires a drilling rig equipped with a high-torque drill bit and a high-power engine. Facing the rock layer, the CFA pile driver must not only be powerful, but also have a drilling depth of 15-30 meters to complete the drilling operation and lay a solid foundation for the bridge.
- Pay attention to equipment performance and parameters: The drilling depth and diameter must meet the engineering design requirements. For example, some large-scale water conservancy projects may require a drilling diameter of 1-2 meters and a drilling depth of 40-70 meters. The power output and lifting force must also be strong enough to ensure the operating efficiency and stability under complex working conditions.
- Consider the budget cost: Consider the purchase price and the subsequent fuel and maintenance costs. The direct sales from the manufacturer are more cost-effective. Compare the cost-effectiveness of models under a limited budget.
- Refer to user feedback: Through the same type of engineering cases and user evaluations, understand the actual performance of equipment construction efficiency, failure rate, etc., and assist in model selection.
