Ground screw,known as helical anchors, piers, screw anchors or screw pilessy,it is a modern foundation system,using the drilling machine to install which makes it as the most efficient and cost-saving footing solution.
They are produced with the use of different sizes of tubular hollow sections for the anchor shaft. The parts may consist of a solid square bar shaft or a hollow tubular shaft with helical plates welded to it. Tubular helical piles have, however, become the standard helical piles.
Due to the design specifications and ease of installation of the helical anchors, they are mostly used when soil conditions do not favor standard foundation solutions. The anchor shaft does the work of structure load transferring to the piles. Helical pile steel plates are welded to the anchor shaft to correspond with soil conditions.
It is a kind of drilling pile with high gripping strength regardless of the terrains, such as sandy soil, marsh and loose earth. According to its excellent durability and stability, ground screw can be used for many kinds of application, like solar system, timer-fram construction, advertising and traffic systems, urban garden and landscape construction, flag poles and so on.
