Bailey Bridge With Professional Erection Guidance

The bailey panel is manually moved to the I-beam through the inclined plane of the lantern frame, which overcomes the process that cannot be completed by a large crane. During construction, in order to ensure the deformation after pouring, 4.5cm of pre-arch was adopted. After actual implementation, the deformation result after pouring is 3cm, which meets the requirements of bridge construction.

Bailey panel is a shaped truss welded by 10# channel steel, each sheet has a size of 3m×1.5m, and its two ends have male and female connectors, which are connected by connecting pins during assembly; in order to strengthen the rigidity of the joints, the joints are used The connecting piece is strengthened. The size of the connecting piece is 0.5m×1.0m. Both the Bailey piece and the connecting piece have bolt holes, which are connected and fixed by bolts during assembly. It can be assembled into single-row single-layer, double-row single-layer, single-row double-layer, double-row double-layer and other forms according to stress requirements. The upper and lower chords of the truss pieces can be reinforced with chords to meet various load requirements need.

During construction, the serpentine column is pre-embedded on the pier column (the height of the column is 1.5m, the height of the bridge is 0.55m), and the steel plate is welded on the serpentine column to install the I-beam, and then the beret is installed on the I-beam. For the truss, three serpentine columns are pre-embedded on each pier column. The Bailey sheet adopts a double-row single-layer structure (a total of four rows of Bailey sheet trusses), in which the distance between the first row and the second row is 50cm; the distance between the second row and the third row is 3m; the third row and the third row The spacing between the four rows is 50cm.
