The spiral steel pile foundation, also known as the steel anchor, is an increasingly widely used form of photovoltaic support foundation. It uses hot-dip galvanized steel pipe piles with spiral blades under the front and rear columns of the photovoltaic support. The spiral blades can be large or small, continuous or intermittent, and the spiral blades and steel pipe piles are continuously welded. During the construction process, professional machinery can be used to screw them into the soil.

 The upper part of the spiral steel pile foundation is exposed above the ground and connected to the upper support column by bolts. Its force mechanism is similar to that of common screws in daily life. It is screwed into the soil by a matching machine, and the lateral friction between the steel pipe pile side and the soil, especially the bite force between the spiral blade and the soil, is used to resist the upward pull force and withstand the vertical load. The pile-soil interaction between the pile body, spiral blade and soil is used to resist the horizontal load. The advantages of spiral steel pile foundation are outstanding. It has fast construction speed, no need for site leveling, no earthwork excavation, and can be selected in various forms according to the geological conditions of the photovoltaic field. It also has very good environmental performance, can protect the vegetation in the field to the maximum extent, has little impact on the environment, and the field is easy to restore to its original appearance.

The spiral steel pile is convenient for adjusting the upper bracket, and the bracket height can be adjusted according to the terrain. The galvanized layer on the surface of the pile body is corrosion-resistant, which can ensure that the spiral pile has considerable bearing capacity underground, so the spiral steel pile can be reused as needed.Powerack offers a wide range of helical ground pile.
