Double-deck steel cable bridge and erection method thereof
The invention discloses a double-deck steel cable bridge and an erection method thereof. The double-deck steel cable bridge comprises a set of upper deck steel cables (2) connected with anchorages (1) arranged on both shores and a set of lower deck steel cables (3). A set of main girders (4) distributed at intervals is arranged between the upper deck steel cables and the lower steel cable. A set of auxiliary girders (5) is arranged between every two main girders (4). Bridge deck slabs (6) are arranged between the main girders (4) and the auxiliary girders (5) or between the auxiliary girders (5). According to the double-deck steel cable bridge, the number of the arranged steel cables can be increased by nearly one time under the condition that the bridge deck width is the same, so that the design of an extra long-span flat cable bridge is made to be possible. Due to the arrangement of the main girders (4), the auxiliary girders (5) and the tension structure, the main girders (4) and the auxiliary girders (5) are firmly fixed to the steel cables, and a spatial structure of the upper deck steel cables and the lower deck steel cables is formed, so that the rigidity of the bridge deck is greatly improved, and the bridge is good in stability, high in safety, simple in structure, convenient to install, and high in recycle rate of the components.
