PURPOSE: A construction method of a multi-span continuous re-prestressed preflex composite bridge is provided to achieve dynamically profitable processes through efficient manufacture and installation of temporary facilities. CONSTITUTION: A construction method of a multi-span continuous re-prestressed preflex composite bridge comprises steps of: preparing steel girder segments including first and second steel beams, setting a steel wire(152), curing a lower casing concrete(160), successively applying a first and a second compressive stress to the lower casing concrete, spanning a first girder between an abutment and a pier, connecting one end of the first girder to the second steel beam(120) to form a main girder part(140), and applying a third compressive stress to the lower casing concrete and a slab concrete. |
