Specification of Steel Arch Bridge: Diagonal Span Arch Bridge:

 Size data
Span lengths68m

1) The surface of bridge applies girder, beam, small girder with cast-in-situ concrete bridge panel to form mixed steel composite beams, and evenly works on two arch ribs through 9 pairs of suspenders. Girder is welded with Q345D grade steel plate with 16mm thickness, so that its cross section is formed as a box, turning outside into tuyere.
2) The beams are set every 6 meters following the direction of bridge, which also is set one small girder, to make sure overall and partial stability of the bridge. Girder, small beams are both welded from Q345D steel plate to form H beams.

Other Characteristics of Steel Arch Bridge: Diagonal Span Arch Bridge:
1) The foundation of abutment applies reinforced concrete structure, and also applies C30 concrete. When abutment and abutment pile caps construction are pouring concrete, effective measures should be taken to lower hydration heat.
2) Abutment Pile styled abutment, in which the foundation of pile is designed based on friction pile, can be made by hole drilling perfusion and hole digging.
