"The spiral pile is one of the most commonly employed foundation piles in photovoltaic ground-mounted power stations. It comprises a central steel tube integrated with multiple helical blades. Based on the configuration of these blades, it can be broadly classified into layered vane spiral piles and continuous vane spiral piles. Spiral piles are typically installed using specialized machinery, allowing for rapid completion within seconds, thereby enabling immediate utilization of the pile foundation post-construction. This method mitigates issues associated with concrete construction and maintenance while significantly reducing labor costs. Moreover, the construction equipment demonstrates high mobility, facilitating swift entry and exit at minimal expense; this type of pile also exhibits exceptional tensile strength, making it suitable for diverse terrains including hills, shoals, and various landscapes.

 

The primary advantages of ground screws include:

1. High Strength: Due to their spiral design and the properties of metal materials, ground screws can withstand substantial loads and are adaptable to various soil types and geological conditions.

2. High Stability: The design of ground screws ensures stability across different environments such as earthquakes, storms, and other adverse weather conditions.

3. Ease of Construction: The installation process for ground screws is relatively straightforward and does not necessitate extensive mechanical equipment or manpower input; thus, construction tasks can be completed in a comparatively short timeframe.

4. Reusability: Ground screws can be utilized multiple times and adjusted or maintained as needed to extend their service life.

In summary, ground screws represent a highly practical infrastructure solution widely adopted in various construction projects due to their high strength, stability, ease of installation, and reusability."
