Freyssinet ElevArch® Bridge Lift Trial
Freyssinet’s ElevArch® technique was trialled in a live demo in front of 120 guests from the rail sector, including Network Rail, Aktins, Arup, Arcadis, DfT and J. Murphy Group. The 161-year-old, 220 tonne masonry arch bridge on Moco Farm in Buckinghamshire was successfully raised 900mm using ten 50 tonne jacks. Freyssinet was invited to participate in RSSB’s Innovation Programme for The Avoidance of Bridge Reconstruction in 2014. From this, the company’s innovative ElevArch® concept was born - a revolutionary technique for vertically jacking masonry bridge arches, designed to minimise intrusion to the rail environment compared to other techniques, significantly reducing cost, time and resources. The ElevArch® lift trial was the result of two years of innovative thinking and careful planning. To find out more about ElevArch®, email firstname.lastname@example.org
Saltings Viaduct Expansion Joint Replacement
The A465 Saltings Viaduct on the Neath Interchange is a busy dual carriage way, bringing traffic to and from the Swansea area. Assessment of the viaduct indicated that essential maintenance was required to replace the expansion joint located on the east side of the bridge on both the westbound and eastbound carriageways. Freyssinet was appointed by the client, Cemex, on behalf of South Wales Trunk Road Agent (SWTRA) for the Welsh Government to design, supply and install a new expansion joint on the bridge. Thousands of vehicles use the bridge every day and as such, every effort was made to minimise inconvenience to road users. Freyssinet installed a cover plate system, which allowed traffic flow during day time hours and the work was completed during night time closures. After removing the existing joint, Freyssinet’s in-house hydrodemolition team Aquaforce removed the surrounding concrete, before installing a fully galvanised Freyssimod LW 480 modular type joint, featuring new swivel bearing supports which allows good operation for whole life.
Freyssinet - HS2 Marston Box Slide - December 2022
The world longest box bridge slide took place over Christmas 2022 to enable the HS2 railway line to cross over the M42 motorway in Warwickshire. In collaboration with Balfour Beatty Vinci (BBV) teams, Freyssinet worked around the clock over the Christmas period to move the 12,600-tonne bridge structure over 163 metres and into position. Freyssinet designed and implemented the sliding mechanism, utilising its Autoripage® technique for heavy handling, which enabled the box to be pushed on a guiding raft and into place.
