BRUECKENKONSTRUKTION.

摘要

A method of constructing a modular bridge across a span, comprises deploying a frame over the back of a launching vehicle (135) on the home bank of the span, placing a first bridge launching rail (133) module on a support for the launching rail on the frame, booming out the launching rail as it is formed and placing subsequent launching rail modules on the launching rail support and coupling them to the launching rail being formed, landing the far end of the launching rail on the far bank of the span, placing a first bridge module (75) on the launching rail and on bridge module support means on the vehicle, launching the bridge along the launching rail as the bridge is formed and placing subsequent bridge modules (31) on the launching rail and on the bridge module support means and coupling them to the bridge being formed.
