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.

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.

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.

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 is a PHC short pile foundation?

PHC short pile foundation is similar to many other structures (e.g. mast arms or overhead structures for signs, signals, luminaires, etc.) that are subjected to torque and lateral load under severe wind speed (e.g., hurricanes).

Does a PHC pile foundation have a separation between soil and soil?

As shown in Fig. 2, the PHC pile foundation in the double-layer site experienced a separation between the foundation and the soil at the 7th load grade. The separation led to a rapid increase in the ground displacement beyond the dial indicator range, and relevant data were not recorded.
