Photovoltaic pipe pile support construction technology
In this study, the frost jacking characteristics of steel pipe screw piles for photovoltaic support foundations in high-latitude and low-altitude regions are studied via in situ tests and numerical simulation. [pdf]FAQs about Photovoltaic pipe pile support construction technology
Are steel pipe piles used in offshore photovoltaic systems horizontal load-bearing?
This study investigates the horizontal load-bearing properties of steel pipe piles used in offshore photovoltaic systems by conducting field tests with single-pile horizontal static loads and performing numerical analysis.
Do photovoltaic support steel pipe screw pile foundations withstand 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.
Why are steel pipe screw piles used in photovoltaic support Foundation projects?
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).
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.
