6 FAQs about [Photovoltaic support anti-pull pile detection]
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.
How good are load tests on driven piles?
The execution of load tests on driven piles and in particular in terms of the number of loading steps, their duration and times of measurement, must be good enough for obtaining conclusions about absolute displacements and residual or non-recoverable displacements.
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.
What is a pile driving equipment?
Pile Driving equipment. Photo 1.- Pile driving equipment Loading device with a minimum capacity of 50 kN that allows to apply the load on the pile in any direction, preferable being operated by a intermediate hoist. Stiff frame for compression tests. Digital dynamometer to measure in any direction with a minimum capacity up to 50 kN.
