6 FAQs about [Connection between cast-in-place pile and photovoltaic bracket]

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.

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.

Can a connection design develop adequate pile moment capacity without special reinforcements?

This study focuses on a thorough understanding of the connection design capable of developing adequate pile moment capacity (while remaining essentially rigid) without providing for any special reinforcements by just relying on a simple plain pile embedment depth.

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.

What is the axial force of a cast-in-place pile?

Most of the pile shaft is subjected to compression, with a maximum axial force of 980 kN occurring at the pile bottom. The overall axial force values satisfied the design requirements. Figure 18 shows the horizontal displacement of the cast-in-place pile at the bottom of the foundation pit.
