PURPOSE: A construction method of a railway bridge using an abutment structure with two posts is provided to remarkably reduce construction time by simplifying a construction process. CONSTITUTION: A construction method of a railway bridge using an abutment structure with two posts is as follows. First and second steel pipe columns(15,16) facing each other are fixed to the construction start positions of a railway bridge. Third and fourth steel pipe columns facing each other are fixed to the construction end positions of the railway bridge. Parts of the first, second, third, and fourth steel pipe columns where are not filled with concrete are filled with concrete, and the filled concrete is cured. First and second horizontal beam molding frames(50a) are placed by crossing the gaps between the first and second steel pipe columns and between the third and fourth steel pipe columns. Reinforcing bars are arranged on the first and second horizontal beam molding frames. The first and second horizontal beam molding frames are integrated with the first, second, third, and fourth steel pipe columns. Bridge bearings are installed on the first and second horizontal beam molding frames. An existing track, a roadbed, and a bridge are removed. A bridge deck is installed on the bridge bearings using a crane. |
