Sliding a 20,000 tonne structure

29 December 2010 - New contracts - Luxembourg

On 31 October, Freyssinet France Agence Câbles et Manutentions, a subsidiary of Soletanche Freyssinet (VINCI Construction), set a new record when it moved a 20,000-tonne motorway structure a distance of 60 metres beneath the tracks, at Belval, of Luxembourg railway operator CFL. This sliding operation, taking 14 hours to complete at a rate of 4 m/h, involved the use of the Autoripage® Freyssinet technique which, in particular, enables an extremely large engineering structure to be slid along while keeping traffic disruption to a minimum.
