METHOD FOR BUILDING A BRIDGE AND BRIDGE-BUILDING APPARATUS

摘要

A method for building a bridge, said bridge comprising piers and at least one deck. The method including a cantilever step, wherein a girder is set in a cantilevered position relative to a bank or to a constructed zone of the bridge so that the girder comprises a first end overhanging the bank or the constructed zone, and a second end overhanging a construction zone of the bridge, and a construction step, wherein pier elements and deck elements are installed in said construction zone via a first and a second lifting devices mounted movable on the girder between the first and second ends. The first and second lifting devices cross one another along the girder during the cantilever step and/or during the construction step.
