Description

Pedestrian overpass Technical Field The utility model relates to the technical field of bridge engineering, in particular to a pedestrian overpass. Background As urban traffic continues to climb, pedestrian safety demands are increasing, and in urban planning, construction of pedestrian overpasses at busy intersections and road sections becomes an important measure. By separating the pedestrian and the motor vehicle streamline, the facility effectively reduces the conflict points of the pedestrian and the motor vehicle, can reduce the occurrence rate of traffic accidents, and can improve the road passing efficiency. As the amount of maintenance of motor vehicles rises dramatically, overhead roads become a critical facility for channeling traffic. At present, most pedestrians cross the street and are concentrated at the ground intersection, but because the traffic flow is dense, the traffic accident risk is obviously increased, and meanwhile, the street-crossing bypass distance of pedestrians and non-motor vehicles on two sides of the overhead land is also greatly prolonged. The existing pedestrian overpass on the overhead road section mainly has two setting modes. Firstly, the overpass is arranged above the overpass, the approach section and the stairway are required to be greatly lifted, the inconvenience is brought to pedestrians for boarding, and the longer stairway occupies a large amount of sidewalk space, so that the service efficiency of urban roads is affected, and the construction cost is greatly increased. Secondly, the overpass is arranged between the main overpass and the auxiliary track, so that the design difficulty of the elevation of the main line is often increased in order to ensure the minimum clear height required by pedestrian traffic, and meanwhile, the layout is extremely unfavorable for the improvement engineering of adding the pedestrian overpass to the later-stage overpass, and has a plurality of limitations. Disclosure of Invention The utility model aims to provide a pedestrian overpass, which is used for solving the problem that the overpass is arranged above an overpass and the ladder way is too long. The utility model discloses a pedestrian overpass, which comprises a first bridge body, a second bridge body, a suspension device, a ladder way and a connecting channel, wherein the first bridge body is arranged on a bridge girder base plate of a bridge span through the suspension device, the second bridge body is arranged at two ends of the first bridge body, the bridge deck of the second bridge body is higher than the bridge deck of the first bridge body, the first bridge body is connected with the second bridge body through the connecting channel, and the ladder way is arranged at one end, far away from the first bridge body, of the second bridge body. Preferably, the suspension device comprises a suspension rod, a first connecting seat, a first pin shaft, a second connecting seat and a second pin shaft, wherein the first connecting seat is arranged at intervals along two sides of the passing direction of the first bridge body, the second connecting seat is arranged on a cross-line bridge box girder bottom plate, the suspension rod is connected with the first connecting seat through the first pin shaft, the suspension rod is connected with the second connecting seat through the second pin shaft, and the first pin shaft and the second pin shaft are mutually perpendicular. Preferably, the arrangement space of the suspenders is 5m. Preferably, the first bridge body adopts a steel box girder structure, and a guardrail is arranged on the first bridge body. Preferably, the second bridge body adopts a steel box girder structure, and the two ends of the second bridge body are provided with first support columns connected with the ground. Preferably, a second support column connected with the ground is arranged at the bottom of the ladder way. Preferably, the connecting channel is a stainless steel step, the gradient of the step is 1:2, and the surface of the step is provided with anti-skid grains. Preferably, the bridge deck of the first bridge body and the bridge deck of the second bridge body are paved with rough granite. The utility model has the following beneficial effects: 1. The utility model fully utilizes the effective space formed by the cross-line bridge cantilever, sinks the bridge deck of the pedestrian overpass, reduces the length and the height of the overpass, improves the comfort of the pedestrians on the bridge on the basis of reducing the crossing and detour distance of pedestrians on two sides of the road, saves the construction cost by adopting the suspension type pedestrian overpass structure, simultaneously provides space for setting municipal infrastructure under the bridge, and realizes intensive and efficient road space. 2. The utility model has convenient and efficient construction, the steel box girder structure can be prefabricated in factories and installed
