Steel Spiral Ground Screw Piles

"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…
