Application: This foundation is mostly used in photovoltaic supports with poor bearing capacity ground, flat sites, low ground water levels and high requirements for uneven settlement.

2.Hammer into the ground pile
Using a pile driver to directly drive C-shaped steel, H-shaped steel or other structural steel into the ground. This installation method is very simple, but the pull-out resistance is poor.
Features: fast speed, strong adaptability; high cost performance; not limited by seasonal temperature; easy to remove ground piles, does not affect the reuse of the installation site; It is difficult to drive piles in areas with hard soil; it is easy to drive galvanized layers in areas with more gravel; use in saline-alkali areas has poor corrosion resistance.
Application: mostly used for silty soil, cohesive soil, filling soil, collapsible loess, etc.

3. Spiral ground screw pile
As an alternative ground screw pile with unique advantages. It has been widely used in the United States, Australia and Europe and other countries, which can meet various engineering requirements such as compression resistance, pullout resistance and horizontal force resistance.
Features: A pipe pile or column pile of Q235B or higher grade steel material (like steel 450 grade) with spiral blades, which is screwed into the ground with special equipment(like the electric ground screw pile driver machine), and the top of the pile is connected to the solar structure. Its advantages are fast and convenient construction, greatly shortening the construction period, and being environmentally friendly. No vegetation can be implemented under various climatic conditions including northern winter and can facilitate migration and recycling.
Application: Gobi, rocky mountains, grasslands, tidal flats, deserts, etc.
