The Original Construction Process Of Bailey Piece Is Like This

The Bailey piece is a shaped truss welded by 10# channel steel. The size of each piece is 3m×1.5m. There are male and female connecting heads at both ends, which are connected by connecting pins during assembly. In order to strengthen the stiffness of the joint, the joint is strengthened with a connecting piece, the size of the connecting piece is 0.5m×1.0m, and there are bolt holes on the Bailey piece and the connecting piece, which are connected and fixed with bolts during assembly. According to the stress needs, it can be assembled into a single row of single layer, double row of single layer, single row of double layer, double row of double layer and other forms. The upper and lower chord bars of the truss pieces can be reinforced by another chord bar to meet the needs of various loads.

During the construction, serpentine columns (1.5m high column, 0.55m higher than the bridge) were embedded on the pier columns, and steel plates were welded to install I-steel on the serpentine columns, and then Bailey truss was built on the I-steel. Three serpentine columns were embedded on each pier column. The structure form of double row and single layer is adopted for the Beret plate (four rows of Beret plate truss in total). The spacing between the first row and the second row is 50cm. 3m between the second row and the third row; The spacing between the third and fourth rows is 50cm.
