摘要

PURPOSE: A temporary bridge system using a circular steel pipe is provided to temporarily install a support structure by using I section steel beam and so on. CONSTITUTION: A temporary bridge system using a circular steel pipe comprises a lower structure(100) and an upper plate structure(200). The lower structure includes a temporary bent. The temporary bent is installed in the ground to be spaced longitudinally. The upper plate structure includes a lining board. A circular steel pipe(300) is installed between the lower structure and the upper plate structure. The circular steel pipe is installed in the upper side of a horizontal beam(110) of the lower structure by a fixing backing plate. The fixing backing plate includes a bolt and a nut. The one or more circular steel pipes are installed in parallel. A horizontal connecting member horizontally restricts the circular steel pipe.
