Wind Turbines
Strong Foundations For The Future
Wind is an abundant, affordable and reliable source of energy.
Enough available to power the UK three times over.
Wind turbines (more properly described as wind energy converters) produce clean electricity using a sustainable source.
Denmark and Germany have led the way in using wind power, with 20% of Denmark’s electricity being generated this way. In parts of Germany the percentage is even higher.
Why choose Aarsleff Piling?
Aarsleff Piling’s parent company Per Aarsleff A/S in Denmark and sister company Centrum Pfahle in Germany have installed driven precast concrete piles for thousands of wind turbines since 1996.
Environmentally friendly technology is supported by an environmentally friendly piling system when ground conditions preclude a mass concrete foundation.
Precast piles use less natural aggregates and cement per unit load bearing capacity than techniques in which the pile is formed in the ground with wet concrete.
Less road transport is required for delivery of materials to site.
On site it is quite normal to achieve high rates of installation and shortened programme periods. There is no waiting time associated with concrete curing before the piles are trimmed and incorporated into the foundation.
Integrity of construction is beyond question with a product manufactured under quality assured factory conditions and with full traceability records.
To erect these structures on poor ground requires a good working platform. The driven precast concrete pile offers a clean foundation solution that will not contaminate or weaken the platform with bore spoil.
The nature of the loads imposed on a wind turbine piled foundation are most efficiently resisted by circular arrangements of piles within a round or octagonal base.
This avoids the potentially asymmetric load distribution in a square or cruciform base that can occur with changes in wind direction.
