TR220W Rotary Drilling Rig is mainlyused in the construction of civil andbridge engineering, which adoptsadvanced intelligent electronic controlsystem and load sensing type pilotcontrol hydraulic system, the wholemachine is safe and reliable.
CFA drilling equipment is suitable for oil drilling equipment, well drilling equipment, rock drilling equipment, directional drilling equipment, and core drilling equipment.
Our CFA drilling equipment based on continuous flight auger drilling technique is mainly used in construction to create concrete piles. It can construct a continuous wall of reinforced concrete that protects workers during excavation.
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,

1-Dry piles
piling 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 The casing can be withdrawn or left in situ.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
