Assembly of Bailey Bridge with Chord Reinforcements

Bailey bridge with chord reinforcements refers to the addition of chord reinforcements on the lattice and lower chord. The structure and connection parts of the bridge are basically the same as those of the non-reinforcement Bridges, except that chord reinforcements are added on the upper and lower chord of each truss in the middle of the bridge except for the first and tail sections. The chord reinforcements and the truss shall be connected with the bolts, and chord reinforcements shall be connected with the bailey pins. In order to prevent the bridge from being obstructed in the process of propulsion, the chord reinforcements are installed in the truss without chord reinforcements at both ends of the bridge.

In double or triple rows of reinforced bridges, the top bracing between the first row and the second row of stiffeners is mounted on chord reinforcements. The bolts connecting frames to the chord reinforcements must be installed on the chord reinforcements in advance before the reinforcement chord is connected to the truss, otherwise the bolts will not be inserted when frame is installed.

The assembly procedure of bridge with chord reinforcements is basically the same as that of non-reinforced bridge, but the operation of assembly chord reinforcements should be increased.
