6 FAQs about [Small cross-section steel piles for photovoltaic 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 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 difference between steel pipe screw pile and PHC pile?
Compared with the PHC pile, the difference in the steel pipe screw pile is that its shaft is thin, the pile-soil friction is small, and the bearing capacity is mainly borne by helical plates.
Are ballasted foundations a good option for helical piles?
Ballasted foundations are also good options for sites which would otherwise be good for helical piles or earth-screws if the ballasted foundations are as cost effective as the other foundations in these cases when the total of install cost, ballast cost, and system cost are calculated.
What is a driven pile?
Driven piles are the simplest and least expensive foundations, and are typically I beams, hat or channel shaped steel sections. These are commonly galvanized to prevent against corrosion and ensure long life under environmental conditions.
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.
