Bridge Support and Jacking

London Bridge Propping and Needling

Bridge support and jacking is a critical service to ensure public safety. Over the past decade, there has been plenty of news on bridge failures and damages, which is where bridge support comes into the fold. The repair, or even replacement, of a bridge and the components, can prove extremely tricky, requiring the expertise of specialist bridge engineers.

We have over 30 years experience in the trade, and our extensive range of bridge bearing and jacking products, as well as our in-house experts, provides a quick, effective solution. Whether you require our lift bridge services or support structures, we have a track record in repair and maintenance. We have worked on a number of key transport bridges, up and down the UK, including the London Bridge and the Croft Bridge in Darlington.

What is bridge support and jacking?

Bridge support and jacking may also be known as structural lifting operations. Essentially, the structural components of the bridge are lifted or supported to allow for replacement and repair. Bridge bearing is integral to ensure the longevity of the bridge structure, thus improving public safety. We can design schemes to lift the bridge, raise bridges of their bearings and support the structure.

Bridge shoring, on the other hand, doesn’t actually move the bridge and can support a live load. However, bridge jacking cannot. Both services are necessary for a number of factors, such as the repair or replacement of girders, beams and piers. Similarly, these bridge services may also be involved in a larger construction or replacement project.

Why is the service necessary?

Bridge support and jacking services ensure the public are safe when crossing bridges. These techniques are completed by professional engineers for effective and speedy infrastructure repairs.

Bridge jacking relieves the entire load of the bridge structure, meaning that repairs can be done for existing components. Typically, hydraulic systems will then replace the beams and bridge bearings. Jacking can also be used when looking to replace the entire bridge.

Hall Construction – Croft Bridge, Darlington

This Girder 500 support system was used to form part support for the existing weakened bridge. A part soffit/falsework application was used during this bridge widening process. This project was complicated due to the skew of the bridge which was overcome by this versatile system.

This Mega-shore support system was used to support the deck on eight separate applications over four carriageways of the A184 bypass, whilst the failed bearing where replaced.
