Hydraulic Bore Pile CFA 23.5m depth Rotary Drilling Rig / CFA machine

Hydraulic Bore Pile Machine TR250W CFA Rotary Drilling Rig

Hydraulic Bore Pile Machine TR250W CFA Rotary Drilling Rig can be equipped with powerful hydraulic rotary head up 120kNm torque for the execution of drilled piles up to 1200 mm diameter over 23.5 meters depth.Larger diameter piles are conceived for deep foundation piles through particularly dense or hard rock:

1-Dry piles
drilling in solid ground without water infiltrations

2-Dry piles with casing protection
Performed when soil is unstable. The casing can be withdrawn or left in situ. Steel casings can be installed by means of the rotary table of the rig, by additional equipment such as hydraulic vibrators or casing oscillator.When the drilling depth is reached, a steel reinforcement is inserted inside the excav-ated pile and concrete is poured by means of tremie pipes.

3-Wet piles
In some cases there may be a need to employ drilling fluids (such as bentonite suspension or biodegradable polymers) in order to maintain a stable shaft

Application field:
-Any kind of soil conditions, including rock formations
-Large and deep piling design
