The invention provides a
pedestrian catenary plate
arch bridge and a construction method thereof.The
pedestrian catenary plate
arch bridge comprises an upper
bridge deck assembly and a lower supporting
assembly, the lower supporting
assembly comprises a cable rotating
saddle, an arch ring assembly and an arch support, the cable rotating
saddle is connected to the top of the arch ring assembly, and the upper
bridge deck assembly comprises a cable anchoring assembly, a cable, a cable clamp assembly and a
bridge deck slab assembly; the two ends of the cable are connected with the corresponding cable anchoring units respectively, the middle of the cable is placed in a cable groove of the cable rotating
saddle, each cable clamping unit comprises a clamping part and a connecting part, the clamping parts are used for clamping the cable, the bridge
deck assembly is located above the cable, and the bridge
deck assembly is connected with the connecting parts of the cable clamping units. The method is suitable for complex terrains such as deep valleys, river valleys and big rivers, temporary facilities such as full framing and cable-stayed buckle hanging needed by a conventional
arch bridge scheme are omitted, the
workload of temporary measures is greatly reduced, the
ecological environment at the bridge site is protected to the maximum degree, and meanwhile the adaptability to the stability of a side slope behind an arch support is good.
