6 FAQs about [Photovoltaic support cast-in-place pile steel cage]
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.
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.
Are cast-in-place concrete piles a research object?
This article focuses on the production of actual cast-in-place concrete piles as the research object. It provides a detailed description of the production process for pile foundation reinforcement cages and quality control methods for reinforcement cages.
Are ground mounting steel frames suitable for PV solar power plant projects?
In the photovoltaic (PV) solar power plant projects, PV solar panel (SP) support structure is one of the main elements and limited numerical studies exist on PVSP ground mounting steel frames to be a research gap that has not be addressed adequately in the literature.
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.
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.
