CIVIL WORK PROJECTS

toll-less motorway Jaca-Santa Cilia

Four two-carriageway bridges (11.80 m), of two beams of between 28-49 m long and between 4-18 isostatic spans, with piles executed “in situ”.

To be highlighted:

• The beams are mounted with the required cant and longitudinal slope, easing the adjustment of the board to the outline.
• The minimum number of beams ensures a high assembling performance.
• The fewer amount of elements, lines and shadows make this typology to be deemed better aesthetically than the double T.
• The permit lodging facilities inside them, when requested by the client.
• They are more appropriate than the double T in the event of low passage over river beds.
• Cantilever slabs are self-supporting and include anchorages for provisional rails during the execution of the slab, side shutters and auxiliary anchorages for the metal sheathing of the impost.
• The reordering of floor slabs is adapted to the curved outline of the bridges.
