6 FAQs about [Advantages and disadvantages of photovoltaic support steel spiral 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.
What are the disadvantages of steel piles?
Steel piles can penetrate through stiff layers or boulders. The volume of soil displaced during the driving of steel piles is less. Steel piles can withstand rough handling. Steel piles have a high possibility of damage from corrosion and electrolysis. Steel piles are relatively expensive unless the bearing stratum can develop large pile capacity.
What are the advantages of using a steel pile?
The most important advantage of using a steel pile is its load-carrying capacity. A steel pile can take up to 100 tons per pile. Steel piles are most commonly used for foundations of large structures with heavy loads. Steel piles have a large bearing capacity. Steel piles can penetrate through stiff layers or boulders.
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.
