TEMPORARY BRIDGE CONSTRUCTION METHOD
To provide a temporary bridge construction method that allows efficient construction without being affected by support pile construction errors, can reduce work in high places and on-site welding work, and with which a substructure unit can be assembled on site.SOLUTION: To correct a construction error of an existing support pile 10, a clamp device 30 is slidably adjusted to allow aligning and assembly in advance of a spacing Lbetween a plurality of support columns 20 to a pile head spacing Lof the existing support pile 10 when assembling a gate-shaped substructure unit 50 into a ground, after cutting the pile head of the support pile 10 driven into the ground to a design height.SELECTED DRAWING: Figure 7
【課題】持杭の施工誤差の影響を受けずに効率よく施工できて、現場における高所作業と溶接作業を減らして下部工ユニットを現場で地組みできる、仮設橋の施工方法を提供すること。【解決手段】地中に打ち込んだ支持杭１０の杭頭を設計高さに切断した後、門型の下部工ユニット５０を地組みするに際し、既設の支持杭１０の施工誤差を修正するように、クランプ装置３０をスライド調整して複数の支持柱２０の間隔Ｌ２を既設の支持杭１０の杭頭間隔Ｌ１に予め合せて組み立てる。【選択図】図７
