The invention discloses a pedestrian overpass and a frame pier. The frame pier comprises pier studs arranged in parallel in the transverse direction of the overpass, pile foundations arranged in parallel in the transverse direction of the overpass and a bearing platform arranged at the tops of the pair of pile foundations arranged in the transverse direction of the overpass and used for bearing the pair of pier studs arranged in the transverse direction of the overpass. A cantilever beam which extends towards the length direction of a standard span main beam at a preset length and is used forbearing the standard span main beam is arranged at the tops of the pier studs. According to the frame pier provided by the invention, the span of the pedestrian overpass can be compensated by adjusting the extending length of the cantilever beam relative to the pier studs arranged in the bridge direction; and for pedestrian overpasses with different spans within a certain range, the pre-machined standard span main beams and the frame piers can be adopted for splicing, and the construction difficulty is reduced, so the construction progress can be effectively accelerated, and the construction cost can be effectively reduced.
Description
technical field [0001] The invention relates to the technical field of bridge design, in particular to a frame bridge pier. The invention also relates to a pedestrian bridge with the frame pier. Background technique [0002] The main scheme of the design of the pedestrian bridge at this stage is to set the main girders of the bridge with different lengths for different spans. [0003] Set end beams and corbels at both ends of the main beam to support the ladder. The location of the main beam bearing stairway needs special design and force calculation. Under the pier of the pedestrian bridge, there must be no immovable pipelines before construction can be carried out, but nowadays urban underground pipelines such as water supply, drainage, military optical fibers, electric wires and optical cables of major companies are arranged on both sides of the main road. More and more . If the pipeline is dense and conflicts with the lower foundation of the pier, the pier cannot be ...
