Construction Method
How the CRD1305H Works
The CRD1305H uses hydraulic rotary torque and vertical force to advance steel casing into the ground while excavation equipment removes soil or underground obstructions from inside the casing.
Typical Construction Process
Set up the casing rotator and align it with the designed pile location.
Rotate and press the steel casing into the ground.
Remove soil, rock fragments or obstacles from inside the casing using suitable excavation tools.
Complete foundation construction and extract the casing according to the approved construction method.
The full casing method helps maintain bore stability during excavation, particularly in difficult ground conditions.
