Problems solved by technology

[0002] Generally speaking, a double-channel bridge includes a bridge deck 1, three arched bridges 2 arranged at intervals, and load-bearing cables connected between bridge 2 and bridge deck 1 3 and the tie rods 7 connected between the tops of the three bridges. The existing tie rods 7 are mainly made of steel materials. Horizontal tension effect, so not only a lot of materials are used, but also time-consuming and labor-intensive processing, and the cost is high
In addition, the existing load-bearing cables 3 are all longitudinally extended and arranged at parallel intervals. Although they can exert a certain longitudinal pulling effect on the bridge deck, the overall stability and load-bearing performance are not particularly high.

Abstract

The invention discloses a reinforced double-channel bridge, which comprises a bridge deck, three arched bridges arranged at intervals and load-bearing cables, the bridge in the middle of the three bridges is an intermediate bridge arranged vertically, and the three The bridges located on both sides of the bridge are side bridges inclined outwards. Several tension cables are respectively stretched between the bridges on both sides and the upper part of the middle bridge. Some of the tension cables are arranged crosswise. Fasteners are fixedly connected; this improves the transverse strength of the bridge, and the overall structure is stable and has better load-bearing performance.

Description

technical field [0001] The invention relates to a double channel bridge. Background technique [0002] Generally speaking, a double-channel bridge includes a bridge deck 1, three arched bridges 2 arranged at intervals, a load-bearing cable 3 connected between the bridge 2 and the bridge deck 1, and a tie rod 7 connected between the tops of the three bridges. The tie rods 7 are mainly made of steel materials. In order to achieve a certain strength, it needs a lot of thicker tie rods 7 to achieve the transverse tension between the bridges. This not only requires a lot of materials, but also takes time and effort to process. higher cost. In addition, the existing load-bearing cables 3 are all longitudinally extended and arranged at parallel intervals. Although they can exert a certain longitudinal pulling effect on the bridge deck, the overall stability and load-bearing performance are not particularly high. Contents of the invention [0003] The object of the invention is ...
