Installation Of Screw Piles

Screw piles are wound into the ground much like a screw into wood.  Screw piles are installed using various earthmoving equipment fitted with rotary hydraulic attachments.  Machinery varies from skid-steer loaders to 5 tonne through 80 tonne excavators.  Rotary hydraulic powerheads with torque capacities ranging from 5,000 Nm to 500,000 Nm are custom fitted using various boom configurations.  Special drive attachments connect the screw pile to the machine.  Correct installation techniques are paramount to meet engineered design load and settlement outcomes.  Incorrect techniques are likely to result in poor overall pile performance.
