Abstract

The invention discloses a temporary concrete steel structure bridge for railway construction, and relates to the technical field of bridges, the temporary concrete steel structure bridge comprises first bridge frames and second bridge frames, one ends of the first bridge frames are provided with the second bridge frames, and the temporary concrete steel structure bridge is formed by mutually splicing a plurality of first bridge frames and second bridge frames; according to the concrete steel structure bridge, the number of the first bridge frames and the number of the second bridge frames can be determined according to the specific construction environment, so that bridges of various lengths can be formed, the concrete steel structure bridge is suitable for various construction environments, and the application range of the device is widened; the steel frame and the concrete prefabricated assembly can be independently stored in the transportation process, assembled during use and disassembled and stored in a classified mode when not used, the transportation convenience and maneuverability are improved, and the cement prefabricated assembly can improve the road holding force of vehicle tires and improve the anti-skid performance of a vehicle by arranging wear-resisting protrusions.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a temporary concrete steel structure bridge for railway construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical ...
