Prefabricated highway steel bridges, usually referring to assembled highway steel bridges, are simply supported truss structure bridges made by quickly assembling standardized metal components prefabricated in factories on-site. Their core advantages lie in rapid deployment, reusability, and strong adaptability, with primary uses focused on emergency and temporary traffic support scenarios.
Emergency Traffic Support: In cases where existing bridges are damaged due to natural disasters (such as earthquakes or floods), war damage, or accidents, prefabricated steel bridges can be quickly erected to restore key traffic routes, ensuring the transport of relief supplies and the evacuation of personnel.
Military Use: The military can leverage their rapid assembly features to quickly construct passageways in the field or on the front line, meeting the traffic requirements of equipment (such as vehicles – level 20, tracked vehicles – level 50).
Temporary Construction Bridges: In large-scale construction projects such as highways and railways, they are used to span rivers or ravines, providing temporary traffic channels for construction. They can be dismantled and reused once the main project is completed.
Replacement for Dangerous Bridges or Temporary Detours During Construction: When renovating or demolishing and rebuilding old or hazardous bridges, they can serve as temporary bridges to ensure uninterrupted traffic.
