Abstract

A trough bridge is composed of a plurality of interconnected bridge sections each formed of a roadway deck segment and side wall segments located at opposite sides of the roadway deck segment. An articulation for pivotally attaching the side wall segments to each roadway deck segment includes spaced and aligned first hinge sleeves affixed to the roadway deck segment; a separate first hinge recess defined next to each first hinge sleeve; spaced and aligned second hinge sleeves affixed to the side wall segments; and a separate second hinge recess defined next to each second hinge sleeve. In an assembled state the first hinge sleeves are received in respective second hinge recesses and the second hinge sleeves are received in respective first hinge recesses. The first and second hinge sleeves are in alignment with one another. A hinge pin passes through the first and second hinge sleeves for pivotally joining the side wall segments to the roadway deck segment. There is further provided a locking arrangement for immobilizing the side wall segments in a predetermined pivotal position relative to the roadway deck segment.
