METHOD FOR CONSTRUCTING TEMPORARY BRIDGE USING MOVABLE BOXGIRDER

摘要

PURPOSE: An advanced construction method of a temporary bridge using a movable box girder is provided to remarkably reduce construction time by consecutively performing pile driving works. CONSTITUTION: An advanced construction method of a temporary bridge using a movable box girder is as follows. Piles are driven into two places along a throttling direction. Moving units(20) composed of horizontal beams, extrusion devices, and sliding girders are installed. Box girders(30) are installed on the sliding girders in a throttling direction. A movable deck(40) is installed on the top of the box girders, and driving equipment(50) is loaded on the movable deck. The driving equipment is moved to a pre-determined position by moving the movable deck. The driving equipment drives piles to be parallel to the piles driven into two places.
