CFA piling rig

CFA Piling Rig, full name Continuous Flight Auger Piling Rig, is a continuous flight auger piling rig. It is a kind of mechanical equipment used for the construction of a building foundation. It is used to form pile holes by rotating the auger rod deep into the ground and synchronously filling concrete during the drilling process, so as to complete the construction of the pile foundation. CFA Pile Driver has unique advantages compared with screw pile driver, rotary drilling rig, and other equipment.

Application Scenarios of Auger Piling Machine

CFA piling machines are used in a wide range of applications.

1. Dense urban areas: vibration-free construction, avoiding impact on neighboring buildings, a perfect alternative to horizontal directional drilling.
2. Soft ground treatment: with a special auger bit, it can effectively solve the problem of collapsed holes, and the efficiency is twice as much as that of a water well drilling rig.
3. Bridge pile foundation: 1.5 meters in diameter, large pile diameter construction, bearing capacity far exceeds the design standard.
4. Wind power foundation: 60 meters ultra-deep drilling capacity, adapting to complex terrain such as mountains and mudflats.
5. Environmentally demanding area: the mud circulation system realizes zero discharge and passes the EU environmental protection certification.
6. In some urban areas with strict noise and vibration restrictions, auger piling machines can also be of great help due to their low noise and vibration characteristics. This is unmatched by horizontal directional drilling and water well drilling rigs.

Advantages of CFA Pile Drivers

The advantages of CFA piling rigs are significant.

1. Its construction efficiency is extremely high, with continuous drilling and filling operations, greatly shortening the construction period.
2. Moreover, the construction quality is reliable, and the synchronized concrete filling ensures the integrity and strength of the piles.
3. It also has good environmental performance with low noise and vibration, which reduces the disturbance to the surrounding environment.
4. At the same time, CFA Pile Driver is highly adaptable and can work under a variety of geological conditions, whether it is soft soil or harder strata, which is difficult for many similar equipment to do.

CFA Pile Driver Structure

The auger piling machine mainly consists of a chassis, a drill frame, a power system, an auger rod, and other parts.

1. The chassis provides stable support for the machine and ensures that it will not shake during the construction process.
2. The auger frame is used to support and guide the lifting and lowering of the auger rod.
3. The power system provides power for the whole equipment, driving the auger rod to rotate and lift.
4. The auger rod is the core component of the CFA piling rig. With its special spiral structure, it can efficiently drill into the ground and deliver concrete into the pile hole.

CFA Pile Driver Working Principle

When working, the CFA Pile Driver first aligns the auger rod to the construction position. The power system drives the auger rod to rotate, and the auger rod gradually drills into the ground by the action of the auger blades until it reaches the designed depth. At this time, concrete is pumped to the bottom of the pile hole through the channels inside the drill pipe. With the slow lifting of the drill pipe, the concrete continuously fills the pile hole to form a solid pile body. Precise control and stable equipment performance are crucial in this process.
