Description

Highway bridge with anti transverse force

Technical Field

The invention relates to the technical field of highway bridges, in particular to a highway bridge with transverse force resistance.

Background

The highway line passes through water areas such as rivers, estuaries, lakes, reservoirs, irrigation canals and the like, or crosses deep valley zones with large height differences or crosses other traffic lines, and bridges are needed to be erected for keeping traffic smooth. In busy urban areas, elevated roads consisting of viaducts are sometimes required. The side mountain road or the elevated bridge is sometimes built because of the huge engineering of digging the roadbed, or because of the unstable geological structure, or because of protecting the landscape, but the roadbed is not built. Bridges crossing rivers are generally provided with high-water-level bridges capable of safely discharging expected maximum flood. In a mountain area, people usually build two ends of a bridge on the mountain walls on two sides of a river respectively, build piers in the river for supporting, in the using process of the bridge, when the bridge meets a flood season, particularly when the mountain area often breaks a landslide, trees on the mountain can slide into the river and flow downstream along with river water, when the bridge meets the piers, trees can cross between two piers due to small distance between some piers and are blocked by the piers, large transverse resistance can be generated in turbulent river water due to large tree volume, so that the transverse force is transmitted to the piers, the piers can bear extremely large transverse force, when more and more trees are blocked between the piers, the hidden danger that the bridge collapses due to the fact that the blocked trees are not convenient to salvage by the existing bridge to reduce the transverse force is caused, for example, CN110777755A/CN204000809U in the existing tree salvage device needs to be provided with a vertical lifting structure and also needs to be provided with knots The structure can realize that the salvaged wood cannot drop accidentally in the process of rising and taking out, but the equipped net is easy to corrode, the cleaning and unfolding are difficult after the salvage, and the net body is inconvenient to return, so that how to provide the transverse force resistant highway bridge with the salvage function is how to provide, and in view of the above, we provide the transverse force resistant highway bridge.
