BRIDGE CONSTRUCTION METHOD AND BRIDGE
To provide a construction method for a bridge which can be easily constructed with a simple structure in places such as remote mountainous areas or valleys with undeveloped roads where it is difficult to prepare large heavy equipment and there are no engineers, and to provide such a bridge.SOLUTION: The present invention relates to a method for constructing a bridge having a bridge length of 10 m to 30 m, which is constructed between slope faces or embankments provided on slopes facing each other across a stream or valley in the mountains, or between banks sandwiching a well-maintained river. The method includes the steps for: installing a bridge girder formed by arranging two steel pipes having a substantially circular cross-section in parallel in a bridging direction in a bridging area; installing a plurality of horizontal girders joined to the two steel pipes at a fixed interval substantially perpendicular to each of the two steel pipes; placing a floor slab on an installed bridge girder; and extending a handrail to each of the two steel pipes or erecting a handrail on the floor slab. The present invention also relates to a bridge constructed by the method.SELECTED DRAWING: Figure 5
【課題】大型の重機を準備することが難しい山間僻地や渓谷、道路等未整備で技術者もいない場所で、簡易な構造で簡単に構築することができる橋梁の施工方法及び斯かる橋梁を提供すること。【解決手段】本発明は、山間の渓流或は渓谷を挟んで向かい合う斜面に設けた法面もしくは盛土、或いは整備された河川を挟む土手の間に架設される、橋長１０ｍから３０ｍの橋梁の施工方法であって、架橋域における架橋方向に、断面が略円形の鋼管２本を平行に配置してなる橋桁を設置する工程と、該２本の鋼管それぞれに対して略直角に、一定間隔をおいて、該２本の鋼管に接合されてなる複数の横桁を設置する工程と、設置された橋桁の上に床版を載置する工程と、前記２本の鋼管それぞれに欄干を延設するか、又は前記床版の上に欄干を立設する工程と、を含んでなることを特徴とする橋梁の施工方法、またはその橋梁に関する。【選択図】図５
