Regional photovoltaic support spiral piles

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.

Do helical pipe piles interact with wind loads?

Presently, helical pipe piles are widely used in solar farms as part of the supporting structure. In this paper, the pile–soil interaction of steel pipe piles and helical pipe piles with wind loads is analyzed using ABAQUS. The Finite Element Method (FEM) models are assessed with varying strength moduli and cohesions of clay.

Can helical plates be used to simulate steel pipe piles?

The numerical simulation method employed in this study was proposed by J.Z., who holds the patent for Blade Pile Group Pty Ltd. For the sake of convenience in future research and comparison, this study only examined steel pipe piles without helical plates and helical pipe piles with a single helical plate.

Is a PHC pile foundation a reliable support structure for heliostats?

A comprehensive design program is proposed based on field tests and numerical simulations, considering deformation and bearing capacity. The study confirms the reliability of the PHC pile foundation as a support structure for heliostats, aiming to offer valuable insights for practical applications.

Do helical pipe piles have lateral load capacity?

While Prasad and Rao investigated the lateral load capacity of helical pipe piles and found that their horizontal bearing capacity was 1.2–1.5 times that of helical plate piles, Abdrabbo and Wakil have emphasized the scarcity of research on helical pipe piles under lateral load.
