Photovoltaic spiral pile support

Can photovoltaic support steel pipe screw piles survive frost jacking?

To study the frost jacking performance of photovoltaic support steel pipe screw pile foundations in seasonally frozen soil areas at high latitudes and low altitudes and prevent excessive frost jacking displacement, this study determines the best geometric parameters of screw piles through in situ tests and simulation methods.

What are the different types of photovoltaic support foundations?

The common forms of photovoltaic support foundations include concrete independent foundations, concrete strip foundations, concrete cast-in-place piles, prestressed high-strength concrete (PHC piles), steel piles and steel pipe screw piles. The first three are cast-in situ piles, and the last three are precast piles.

What is a photovoltaic support foundation?

Photovoltaic support foundations are important components of photovoltaic generation systems, which bear the self-weight of support and photovoltaic modules, wind, snow, earthquakes and other loads.

Can steel piles withstand high wind loads?

Case study #1 (steel piles in windy environments): A solar farm in a coastal area with high wind loads utilized steel piles with additional corrosion protection. The flexibility of steel allowed the piles to withstand both the high wind forces and the corrosive coastal environment.

What are steel pipe screw piles?

Among them, steel pipe screw piles are widely used in photovoltaic support foundation projects in various countries and Western China ( Zarrabi and Eslami, 2016, Chen et al., 2018) because they have simple and fast construction, less noise and vibration and can be reused ( Livneh and El Naggar, 2008, Aydin et al., 2011, Mohajerani et al., 2016 ).

Can versol mount a photovoltaic power station?

Versol's V-Basic mounting system can be applied to photovoltaic power station in different terrain and environment. The product range includes a wide range of models and styles, and is highly adaptable.
