ERECTION METHOD OF SIMPLE TEMPORARY BRIDGE
PROBLEM TO BE SOLVED: To provide an erection method of a simple temporary bridge capable of largely reducing construction cost by using general-purpose materials, and capable of simplifying the materials for constituting a superstructure of the simple temporary bridge.SOLUTION: A process of extending a manual-extending temporary girder 30 toward the bridge axial direction by connecting to an existing superstructure, a process of removing a side girth 32 while leaving a girder bearer 31 erected between head parts of a plurality of erected support piles 20 as it is and a process of assembling the superstructure by mounting a plurality of main girders 40 between the girder bearers 31 separated at an interval, are repeatedly executed by a span unit by using the manual-extending temporary girder 30 presenting a plane U shape having the girder bearer 31 with a pile guide cylinder 33 and a pair of detachably connected side girths 32.SELECTED DRAWING: Figure 1
【課題】汎用資材を使用できて工費の大幅削減が可能であるとともに、簡易仮橋の上部工を構成する資材を簡略化できる簡易仮橋の架設方法を提供すること。【解決手段】杭ガイド筒３３を具備した桁受材３１と、着脱可能に連結した一対の側方つなぎ材３２とを具備した平面コ字形を呈する手延仮桁３０を使用し、既設上部工に連結して手延仮桁３０を橋軸方向へ向けて延設する工程と、立設した複数の支持杭２０の頭部間に架設した桁受材３１を残置しつつ、側方つなぎ材３２を撤去する工程と、間隔を隔てた桁受材３１の間に複数の主桁４０を搭載して上部工を組み立てる工程とをスパン単位で繰り返して行う。【選択図】図１
