RAPID CNSTRUCTION METHOD OF SEMI-INTEGRAL ABUTMENT BRIDGE USING PRESTRESSED CONCRETE GIRDER HAVING END DIAPHRAGM

摘要

PURPOSE: A rapid construction method of a semi-integral abutment bridge is provided to improve the ability to construct and economic efficiency by partially replacing an abutment wall with a partition to reduce the height and thickness of the abutment wall. CONSTITUTION: A rapid construction method of a semi-integral abutment bridge comprises the following steps: installing a bridge support on the top of a bride foundation and producing a stem-shaped PSC girder(10) integrated with an abutment partition(12); holding the abutment partition of a girder end on the bridge support and connecting the neighboring girders through a horizontal beam; charging non-shrinking mortar and integrally connecting the partition of the neighboring girder ends; and backfilling the rear side of an abutment and simultaneously constructing a bottom plate and a connecting slab.
