The Advantages of Driven Precast Concrete Piling

Описание: This short video provides an insight into the advantages of driven precast concrete piling.

UK construction must start embracing the many benefits of precast driven piling. Aarsleff Ground Engineering Ltd is championing this perception change and growing rapidly as a result. Technically, precast piles present an alternative, robust and cost-effective piling solution for many civil engineering and infrastructure projects, especially over methods currently deployed. From the reinforcing steel that gives the reinforced concrete pile its strength, most of which is from recycled sources, sustainability is engineered into driven piles. Aarsleff’s piles are manufactured off-site at its sister company Centrum Precast Solutions, which is a fully quality-controlled environment. Waste is managed, recycled and innovation of the concrete processes has led to a vast reduction in cement use. Off-site pile manufacture has also been recognised as offering further environmental benefits, not least in the ability to provide “just-in-time” deliveries, minimising disruption to the local neighbourhood. A precast driven pile, dependent on geology, will typically mobilise higher values of shaft adhesion, often allowing the use of shorter piles than those of a similar section size, formed using wet concrete placed in the ground. This too brings considerable material savings, especially on large developments and an associated CO2 saving from cement manufacture and from the associated reduction in fuel use through fewer on-site machine-hours. In addition, precast concrete piles displace soil as they are driven, so there is no bore spoil to handle and remove from site. Not having to remove bore spoil from site saves a considerable amount of CO2 and cost from a reduction in traffic.

Aarsleff is part of an international group of companies with offices all over Europe, and as such can draw on vast knowledge resources to offer piling and ground engineering solutions to the UK construction sector. Read more: www.aarsleff.co.uk
