BRIDGE RAILWAY BALLASTING CONSTRUCTION METHOD USING TEMPORARY BENT

摘要

PURPOSE: A ballast method for a railway bridge using a temporary bent is provided to set a ballast upper structure on an accurate position after safely and quickly moving the ballast upper structure, thereby more quickly and effectively implementing the ballast of the railway bridge. CONSTITUTION: A ballast method for a railway bridge using a temporary bent includes: a step of installing a transverse rail at the sides of a ballastless bridge installed at an abutment and a pier; a step of installing a temporary bent(200) at the transverse rail so that the temporary bent of which the lower portion is equipped with rollers and directly moves along the transverse rail; a step of assembling and completing a ballast upper structure(100) on the upper surface of the temporary bent; a step of removing the ballastless bridge, moving the temporary bent on the ballast-upper structure along the transverse rail, and then settling the temporary bent on a position in which the ballastless railway bridge is installed; and a step of restoring the temporary bent along the transverse rail.
