The ground screw is formed by welding blades after steel pipe forming. Different blades can increase the different bearing

capacity and drawing capacity of the ground pile. The shape of the blades (single blade, double blade, multi blade, etc.) can 

be selected according to the terrain and land characteristics. The ground screw construction is simple, does not pollute the 

environment, has no vibration and soil dumping during the pile driving process, has low noise and long service life, and can 

be used repeatedly. Screw pile can also increase the compactness of soil around the pile, and increase the resistance and 

bearing capacity. It is widely used in photovoltaic projects, fence foundations, housing construction, road signs, billboards, etc.
