6 FAQs about [Prestressed photovoltaic pipe pile support construction]

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 PHC (pre-stressed high-strength concrete) pile foundation?

The PHC (pre-stressed high-strength concrete) pile foundation, serving as an innovative supporting structure for solar power stations, is subjected to complex loading conditions in engineering scenarios.

Are driven piles suitable for ground mount solar panels?

The design for uplift behavior of shallow footings has been discussed extensively by Kulhawy (1985) and Trautmann & Kulhawy (1988). Driven piles are an attractive foundation alternative for ground mount solar panel systems since the materials are readily available and Contractors are familiar with the technology.

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 ).

What is the Frost jacking of the photovoltaic pile?

Considering the thawing settlement of the pile body, within the 25-year service period of the photovoltaic power project, the frost jacking of the pile is approximately 144.68 mm. anti-frost jacking measures are recommended to reduce the impact of frost heaving.
