The subject of the invention is a rapid construction method for bridges with an upper track.n n n The method according to the invention notably comprises the installation of prefabricated elements (8) of concrete, in the form of a gantry. These elements (8) are attached to foundation pedestals (12) to form spans (2, 3, 4, 5). These elements (8) are joined together by the pouring of a second phase concrete (17), on the whole of the decking formed by the gantries (8) placed side by side.n n n Thanks to the method according to the invention, it is possible to achieve, for a moderate cost, a crossing for a fast lane (7), by greatly reducing, compared to a conventional construction method, the disruption of traffic on this lane. |
