Construction Design of Pile Anchor Support in Deep Foundation

As shown in Figure 1, the pile anchor support structure consists of cast-in-place pile and anchor cable [12]. The cast -in-place pile is a pile formed by drilling and pouring concrete into the

Accurate detection technology of super long bored cast-in-place pile

If it is careless, it is prone to various forms of quality defects, such as pile shrinkage, diameter expansion, mud inclusion, broken pile, too thick sediment and dislocation

Thermal characteristics of cast-in-place pile foundations in warm

Pile foundations are widely used all over the world. The thermal characteristics of some pile foundations have been of concern, including those of energy piles (Rotta Loria and

Frontiers | Reliability analysis of the cast-in-place bored pile with

A super high-rise building with a total height of 530 m was constructed in Tianjin, China. It was designed to use 1,262 cast-in-place bored piles and a raft foundation to support

The difference between cast-in-place piles and precast piles

Piles can be divided into precast piles (prestressed pipe piles) and cast-in-place piles (bored cast-in-place piles) according to different construction methods. Both are widely used in soft soil

6 FAQs about [Photovoltaic support cast-in-place pile design]

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.

Are driven piles suitable for ground mount solar panels?

The design for uplift behavior of shallow footings has been discussed extensively by Kulhawy (1985) and Trautmann & Kulhawy (1988). Driven piles are an attractive foundation alternative for ground mount solar panel systems since the materials are readily available and Contractors are familiar with the technology.

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.

What is a drive pile for a ground mount solar system?

Driven piles to support ground mount solar systems are typically lighter duty that those used for other structural applications with pipes typically in diameters ranging from 4 to 8 in. in diameter and H-piles typically made from W sections with flanges between 6 and 10 in.

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.
