Tilting of arches for the viaduct over the Tera River, Spain

Overview

ALE has completed the tilting of two steel semi-arches, P2 and P3, for the viaduct over the Tera River in Zamora, Spain.

Services Required

P2, which formed part of the bridge’s central deck section, weighed 303t and measured 84m in length. P3 weighed 272t and measured 81m in length. In order to perform the tilting, two hydraulic units of 500t each were used per semi-arch, along with a pair of auxiliary telescopic jacks to start the operation and to break the initial arches’ balance.

Four double effect jacks, of 300t and 150mm stroke, were installed at each swivel base of the two semi-arches. This was carried out to set the longitudinal movements of the arches in order to carry out the final adjustment.
