6 FAQs about [Photovoltaic support pile pulling experiment]

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.

How a load is applied to a pile?

The application of the load to the pile can be carried out either through the construction of a loading frame, or by employing heavy machinery as a reaction, applying the load with a pulley system or hoist in the case of axial tensile load tests and lateral load tests, or with a hydraulic jack in the case of compression tests.

Why are shaped piles used in power transmission towers & photovoltaic panels?

Shaped piles are widely used as the foundation of power transmission towers and photovoltaic panels because of its high bearing capacity and material utilization.

How high should a pile be for a photovoltaic plant?

In any case, for the types of piles that are being used in the foundations of photovoltaic plants, it is recommended that the height of load application will be in order of 1,0 m and in no case exceeding 1,5 m.

Why do helical piles have a high pull-out resistance?

The helical pile provides better pull-out resistance at lesser foundation depth required. The surface area of the bearing plate provides high pull-out resistance, even in loose soils. Helical piles are not well suited to hard soils and soils with very coarse gravel or rock fragments.
