The spiral pile is among the most widely utilized foundation piles in photovoltaic ground-mounted power stations. It consists of a central steel tube integrated with several helical blades. Based on the arrangement of these blades, it can be broadly categorized into layered vane spiral piles and continuous vane spiral piles. Spiral piles are typically installed using specialized machinery, allowing for completion within seconds, enabling immediate use of the pile foundation post-construction. This method eliminates issues related to concrete construction and maintenance while significantly reducing labor costs. Furthermore, the construction equipment exhibits high mobility, facilitating quick entry and exit at a low cost; this type of pile also possesses high tensile strength, making it suitable for various terrains including hills, shoals, and other landscapes.
The main advantages of Ground Screw include: 1. High strength: Due to its spiral shape and the characteristics of metal materials, ground screw are able to withstand large loads and are suitable for various soil types and geological conditions. 2. High stability: The design of ground screw allows them to remain stable in various environments, such as earthquakes, storms and other adverse weather conditions. 3. Easy construction: The installation of ground screw is relatively simple and does not require a lot of mechanical equipment and manpower input, so the construction task can be completed in a relatively short time. 4. Reusable: ground screw can be used many times and can be adjusted and maintained as needed to extend their service life. In short, ground screw are a very practical infrastructure and are widely used in various construction projects. Its high strength, high stability, ease of construction and reusability make it a popular solution.
