PRECAST PSC T-TYPE GIRDER BRIDGE AND ITS CONSTRUCTION METHOD

摘要

PURPOSE: An T-prestressed concrete girder bridge and a construction method thereof are provided to save a bridge construction period by connecting the T-type girders in order to complete an upper part of a bridge. CONSTITUTION: An abutment(200) and a pier excepting a part of a wall are constructed to secure a space. A T-type PSC inner side girder(120), in which a sheath for a second tendon is formed in inside, is established on the abutment and the bridge post in a cross direction. The upper flange of an outside girder(140) and a PSC T-type inner side girder, a partition wall, and a cross beam are interlinked each other in the cross right angle direction. A tendon member is inserted in the sheath for the second tendon in order to pass through the T-type inner side girder and T-type outside girder.
