INTEGRAL BRIDGE AND CONSTRUCTION METHOD USING ARCHED AND CONCRETE-FILLED TUBE

摘要

PURPOSE: A bridge using a composite girder formed by end blocks and arch ribs and a construction method thereof are provided to cost-efficiently improve resistance to a load by manufacturing end blocks using concrete. CONSTITUTION: A bridge using a composite girder formed by an end block and an arch rib comprises end blocks(100), arch ribs(200), vertical ribs(300), and a slab. The end blocks are arranged to be longitudinally separated from each other. The arch ribs are arranged between the end blocks, and both ends of the arch ribs are connected to the inner surfaces of the end blocks. The vertical ribs are extended upward from the tops of the arch ribs and are filled with concrete. The slab is arranged to touch the top surfaces of the vertical ribs and the unit blocks.
