The screw piles are provided in modular sections approximately 2m
long. The lead section normally has three galvanized steel helices
of increasing size welded to the shaft. If further depth is
required, 2m follower sections are provided. Galvanized steel pile
caps are also available.
Helical piers, also known as anchors, piles or screw piles, are
deep foundation solutions used to secure new or repair existing
foundations,a modern improvement to traditional cement footings.
Each pier consists of an engineered steel post with screw-like
helices. Helical pile is extendable base equipment which is made up
of helical engineered metallic plates that are attached to a
central steel shaft using a round or rectangular cross-section. The
steel plate thickness, diameter, number, and helices operate are
determined through the restricted or supported arrangement's
minimal design life, the ecological rust, and geotechnical
parameters, along with the design fill demands.
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.
