6 FAQs about [Cfa drilling rigs]

What is a CFA rig?

Here are some details about a CFA rig: - Key Components of a CFA Rig: 1)Drill Mast: The vertical structure that supports the drill string and auger. 2)Auger: A continuous flight auger that drills into the ground and brings excavated material to the surface. 3)Rotary Head: Drives the auger into the ground and controls the drilling process.

What is a continuous flight auger (CFA)?

CFA (continuous flight auger) is a single pass piling method, where a continuous flight auger is used to drill to depth. During the grouting phase, concrete is pumped through the auger simultaneously with the extraction of the auger from the ground. Usually, a computer is used to monitor the concrete flow and pressure to ensure the pile integrity.

What is the difference between CFA and rotary rigs?

In summary, CFA rigs are ideal for projects requiring minimal disturbance and efficient, continuous pile installation, while rotary rigs offer greater versatility and depth capabilities, making them suitable for a wider range of soil conditions and deeper foundations.

What is a Keller CFA / ACIP rig?

All Keller CFA / ACIP rigs are equipped with sensitive state-of-the-art instrumentation that monitors all aspects of CFA /ACIP piling, including pile depth, auger rotation, penetration rate, concreting pressure, extraction rate, and over-break.

How does a CFA drill work?

Drilling begins with the CFA tool rotating clockwise as crowd force is applied to the auger. The tooling is advanced with high torque rotation and crowd so installation proceeds rapidly and without over-rotation. Morris-Shea’s powerful drill rigs can exert up to 50 tons of torque, 45 tons of crowd force and 120 tons of extraction force.

How deep can a CFA pile be installed?

Our fleet of powerful drill rigs can install CFA piles in diameters from 14 inches to 5 feet with maximum depths to 165 feet. Prior to the start of drilling, the pile number is entered into the Morris-Shea onboard Automated Monitoring System. Drilling begins with the CFA tool rotating clockwise as crowd force is applied to the auger.
