A strong attachment to rail Cintec International has helped to strengthen the UK’s transport infrastructure using its anchoring system to lengthen their life and make journeys safer


ewport-based structural engineering company, Cintec International, is helping a number of contractors involved in Network Rail’s programme of electrification and improvement to the rail infrastructure across the UK. Essential to the electrification process, the work utilises Cintec’s patented anchoring system to support the weight of the gantries that will hold the cables needed to electrify the lines, and in some cases to strengthen railway bridges and viaducts to which the gantries are attached.

London Bridge station Cintec’s recently completed projects include its work on the Thameslink Programme as part of the main line upgrade. This project on the Western Approach signal gantry (cantilever gantry no. XTA1793), which is just outside London Bridge station, demanded close cooperation with Lundy Projects and main contractor Balfour Beatty to reinforce masonry and anchoring. Cintec supplied and installed all the anchors for fixing the new gantries to the brickwork of the viaducts, upon which they are placed as cantilevers over the railway lines. All anchors have been highload threaded bars, 30mm diameter in

a 76mm diameter diamond-core drilled hole and between four and nine metres in length. The drilling and installation had to completed to a very high degree of accuracy to ensure perfect alignment with the major steelwork support structures. A double template was used for the anchor location, with accurate setting out completed by Balfour Beatty Rail for the drilling locations. Jonathan Andrews, project manager for Thameslink KO2 Lundy Projects, and subcontractor to Balfour Beatty, said: ‘The complexity of the work needed on the Western Approach signal gantry demanded the highest level of accuracy
