Modularized steel die and concrete combined arch bridge and suspending construction method of suspension cable thereof
The invention provides a modularized steel die and concrete combined arch bridge and a suspending construction method of a suspension cable thereof in the technical field of bridge building. The modularized steel die and concrete combined arch bridge comprises a combined arch ring with cast-in-place concrete, and vertical stand columns, a bridge deck beam and a bridge deck plate which are arranged on the combined arch ring, wherein the modularized combined arch ring is formed from one or multiple split mounting type steel arches, and each split mounting type steel arch comprises a plurality of modularized steel die units which are fixedly connected in the arc length direction. Modularized production of the steel die units can be carried out in a factory, and the manufacturing cost is low and the transport is convenient. The modularized steel die and concrete combined arch bridge is excellent in integral performance; due to the adoption of the steel die units, a large quantity of templates used when a traditional concrete pouring construction method is adopted are no longer needed, and manpower waste caused by disassembly after the completion of the arc bridge is also avoided; requirements for the combined arch ring with a larger span and a higher construction rigidity can be met, and the requirements for different spans and rigidities as well as construction stability can be met.
