How to deal with the collapse of photovoltaic board pile foundation

Can helical piles be used for ground-mounted solar PV systems?

For ground-mounted solar PV systems, two different pile foundation types were experimentally analysed for the pull-out test in clayey, sandy, and mixed ( c – ϕ) soils. Maximum uplift load at failure of various diameter and length were compared for plain piles with helical piles.

How to deal with the collapse of soil in pile bore holes?

In order to deal with the collapse of soil in pile bore holes due to construction wastes, this essay discusses four possible solutions. By comparing the advantages and disadvantages of these solutions, the method of Manual boring + Machinery boring is finally chosen. This provides a reference to other similar construction projects.

Why is helical pile a good choice for solar installation?

Cost per watt in solar installation is required to be minimum; thus, the depth of foundation is required to be minimum. 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.

What are the problems encountered during pile foundation construction?

There are several issues that may be encountered during pile foundation construction. These problems will cause deficiency in the capacity of the pile unless they tackled properly. These pile construction problems and with their causes and required measure to prevent them are discussed in the following sections.

Are solar farms a good market for Pile Driving Contractors?

As the demand for renewable energy increases—solar farms are becoming an ideal market for pile driving contractors due to the need for stable, long-lasting foundations that can support large-scale solar installations.

How to improve pull-out resistance of solar array foundations?

To improve pull-out resistance of solar array foundations, a comparative experimental study was done to determine the pull-out capacity of steel pile having varying diameter and length in three different soil conditions, i.e. clayey soil, sandy soil, and mixed soil.
