Precast piles
MOJO solar project
A new pile solution for photovoltaic carports in the Netherlands
For the MOJO solar project in the Dutch province of Flevoland, Aarsleff Grundbau GmbH delivered a new kind of foundation solution in 2021: around 2,800 purpose developed Centrum piles act as load bearing foundations and as mounting bases for a photovoltaic carport system at once.
- Precast piles
- approx. 2,800
- Cross section
- 45 × 45 cm
- Pile head
- 45 × 67 cm
- Pile length
- 5 m
- Threaded bolts
- M36
- Ground
- silt, fine sand, sand
The task
The ground consists of silt, fine sand and fine to medium sand. The piles had to carry high horizontal and bending loads from the carport system while staying short enough to remain economical.
Design
Sizing the piles, short lengths with a widened head and integrated M36 threaded bolts, took the high horizontal and bending loads into account and was optimised with the calculation core of piledesigner.io.
