CFA drilling equipment based on continuous flight auger drilling technique is mainly used in construction to create concrete piles. CFA piles continue the advantages of the driven piles and the bored piles, which are versatile and require no removal of soil. This drilling method enables the drilling equipment to excavate a wide variety of soils, dry or water-logged, loose or cohesive, and also to penetrate through low capacity, soft rock formation like tuff, loamy clays, limestone clays, limestone and sandstone etc, The maximum diameter of piling reaches 1.2 m and max. depth achieves 30 m, helping overcome problems formerly connected to project and execution of pilings.

Frequently Asked Questions
What are the primary applications and benefits of CFA drilling equipment?
CFA (Continuous Flight Auger) drilling equipment is mainly used in construction to create concrete piles. It combines the advantages of driven and bored piles, making it highly versatile while requiring no soil removal.
What kinds of geological conditions can this equipment excavate?
This equipment can excavate a wide variety of soils (both dry or water-logged, loose or cohesive) and penetrate soft rock formations such as tuff, loamy clays, limestone clays, limestone, and sandstone.
What is the maximum drilling performance in terms of depth and diameter?
The system can achieve a maximum piling diameter of 1.2 m and a maximum depth of 30 m, which helps overcome complex project execution challenges. Note that specific configuration standards show a 20m depth and 1000mm diameter.
How is construction precision ensured during drilling?
Precision is maintained through an integrated concrete volume display system for exact measurement, an innovative high-precision depth measurement system, and a mast that automatically adjusts the vertical to improve hole accuracy.
What safety and design innovations are included?
