The invention discloses a tension-fabricated bridge with prestressed hollow-plate-girders and middle transverse partitions and a construction method of the tension-fabricated bridge with prestressed hollow-plate-girders and middle transverse partitions. The existing prestressed hollow
plate girder bridge connected via hinge joints is easy to crack and break or fail in bending and shearing. The tension-fabricated bridge with prestressed hollow-plate-girders and middle transverse partitions comprises prestressed hollow plate girders, longitudinal prestressed pipes, longitudinal prestressed steel strands, girder-end anchors, mid-span transverse partitions, transverse prestressed steel pipes, transverse prestressed steel strands, inter-plate-girder connecting rebars, inter-plate-girder longitudinal stressed rebars, cast-in-place connecting section concrete, side-beam lateral anchors and
deck pavement rebars. The transverse partitions are disposed in the middle of the span of the prestressed hollow-plate-girders, and the reserved prestressed pipes are embedded for transverse prestressed tension of the prefabricated bridge. Therefore, single-slab stress,
deck cracking and bridge plate bottom
cracking of the traditionally assembled hollow
plate girder bridge are effectively avoided, and structural durability is enhanced. The construction method is simple and practical and has evident economic technical benefit.
