CONSTRUCTION METHOD FOR SIMPLE TEMPORARY BRIDGE
To provide a construction method for a simple temporary bridge that can be constructed with improved work safety and construction efficiency.SOLUTION: In a construction method for a simple temporary bridge, a suspension device 50 in which a main girder unit 30 that constitutes a superstructure in span units, a reaction force column 51, a first cable tension member 53, a second cable tension member 54 made of rope, and a safety cable tension member 55 are unitized is used. The main girder unit 30 for extension is supported by the first cable tension member 53 that is stretched between the reaction force column 51 and the existing superstructure by connecting the second cable tension member 54 to the main girder unit 30 for extension that is placed in front of the existing superstructure by a crane, and the second cable tension member 54 which is tensioned by performing the tensioning operation of the second cable tension member 54 on the existing superstructure.SELECTED DRAWING: Figure 1
【課題】作業の安全性と施工効率を高めて施工できる簡易仮橋の架設工法を提供する。【解決手段】簡易仮橋の架設工法であって、スパン単位で上部工を構成する主桁ユニット３０と、反力支柱５１、第１斜張材５３、ロープ製の第２斜張材５４、および安全斜張材５５とをユニット化した懸架装置５０を使用し、既設上部工の前方にクレーンで吊り下げて配置した延長用の主桁ユニット３０に第２斜張材５４を連結し、反力支柱５１と既設上部工の間に張設した第１斜張材５３と、既設上部工上で第２斜張材５４の緊張操作を行って張設した第２斜張材５４とにより、延長用の主桁ユニット３０を支持するようにした。【選択図】図１
