The surface of the hot forged metal pipe is welded with a pipe pile wrapped with spiral blades, which mainly consists of three parts: the hot forged pipe body, spiral blades, and connecting flange plate. The spiral blades and flange plate are welded to the pipe body, and then the overall hot dip galvanizing treatment is carried out. The dedicated spiral ground pile tightening equipment is screwed into the ground to replace the original concrete foundation, with the top connected to the load.
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.

All above sizes, steel grade are customizable. |
Helical anchors can be installed with any of the equipment:
This versatility, along with the ability to immediately load and test the anchors, make helicals a convenient and economical solution for a wide variety of concrete stabilization and foundation repair projects.
