The launching of the Mincio viaduct

The launching of the Mincio viaduct has been completed as part of the construction works of the HS/HC Brescia Est – Verona railway line.
A 320 meter viaduct characterized by a particular push launching method in multiple time phases. Steel Project Engineering developed on behalf of Cimolai S.p.A. the Decks Launching Project.
The object of the launching are the three metal spans (50m + 72m + 50m) of the eight that overall make up the railway bridge deck.
The metal girders are 3.2 m high, with the exception of the central one which has a variable height between 3.20m and 4.80m and are made up of a rectilinear trapezoidal box deck in a steel-concrete composite system.
The launching was carried out using a pulling system consisting of a hydraulic jack and a strand cable connected at one end to a fixed point and at the other to the intrados of the caisson.

The bridge was made to slide on roller conveyors located on the definitive and temporary piers and on the launching field. During the launching procedure, adjustments were made to the forearm and the height adjustments of the struts on which the roller conveyors rested, in order to proceed with the advancements, adapting correctly to the shape of the bridge’s intrados. We thank Cimolai S.p.A. for the trust placed. For further information we share some recent publications: Linkedin post – https://www.cepavdue.it/completeto-il-varo-del-viadotto-mincio/
