THROUGH BRIDGE CONSTRUCTION METHOD BY PSC SIDE BEAM AND SLAB

摘要

PURPOSE: A trough bridge construction method using PSC side beam and slab is provided to install a rail on the slab of a railway bridge. CONSTITUTION: A trough bridge construction method using PSC side beam and slab is as follows A bridge post and a bridge lower part structure including the bridge post are installed in a vertical direction. A both side beam(110) is installed on the PSC to be separated in the traverse direction by using a lifting device. A slab is formed between inner lower parts of the both side beam to be integrated with the both side beam. The slab and the both side beam are formed to make both side part of the slab directly stacked on the upper side of the lower flange. The slab passes through the traverse direction and integrated with the outside side of the side beam using a horizontal tensioning member.
