The ground screw is a second-generation screw pile, it is a pipe with blades of a special configuration. Thanks to this design, the ground screw easily penetrates the ground by screwing.
A helical ground screw has a tip and blades of a specially designed shape which by immersion do not loosen the soil but on the contrary - each subsequent coil compresses it. The ground screw blades evenly distribute the load along the entire pile shaft.
The ground screw consists of a tip, a cone, a trunk and also the main screw part which provides all bearing capacity. A key feature of the ground screw is the tip. There are three types of tips: hexagon, square and U-shaped. For alternative electric power plants are used flange-free ground scalers.
