Steel truss mid-support arch bridge exhibition model rail transit science, bridge engineering

The classification of top-bearing, middle-bearing and bottom-bearing arch bridges is mainly based on the position of the carriageway of the arch bridge. The traffic lane system (bridge deck system) above the arch rib is called a top-supporting mid-support arch bridge. The traffic lane system is located in the middle of the arch rib sagittal height. Part of the bridge deck system is suspended under the arch rib with suspenders and part is supported by columns. On the ribs. Similarly, the roadway of a down-bearing arch bridge is located under the arch ribs and suspenders.
Main building materials. The steel pipe arch ribs are filled with concrete: micro-expansion concrete. Longitudinal (tie) beam concrete: concrete. Beam: concrete. Bridge deck: concrete. Bridge deck paving: waterproof concrete
