EMERGENCY TEMPORARY BRIDGE AND CONSTRUCTION METHOD THEREOF
To provide a temporal bridge that can be erected on an emergency basis to save lives and transport supplies in an event of flooding.SOLUTION: An air beam 20, which has a span longer than a distance of a rising water area 3 between an erection starting point side shore 1 and a reaching side shore 2, and whose inner space 21 serves as a passageway, is manufactured by expansion and deployment at the erection starting point side shore 1. The air beam 20 is supported at one end of a bridge end support body 30 provided at the erection starting point side shore 1 and is turned in substantially horizontal around its turning center via a turn table 31 of the bridge end support body 30 until the other end is located on the reaching side shore 2. The other end of the air beam is supported on an airbag bridge abutment 25. This constructs an air beam bridge 10 between the erection starting point side shore 1 and the reaching side shore 2 as an emergency temporal bridge.SELECTED DRAWING: Figure 1
【課題】水害発生時に、人命救助、物資搬送等のために緊急に架設可能な仮設橋を提供する。【解決手段】 架設起点側岸１と到達側岸２との間の増水域３の距離よりも長いスパンを有し、内部空間２１が通路となるエアビーム２０を、架設起点側岸１で膨張展開して製作する。エアビーム２０を、架設起点側岸１に設けた橋端支持体３０に一端を支持させて橋端支持体３０のターンテーブル３１を介して、その旋回中心周りに、他端が到達側岸２に位置するまで略水平旋回させる。エアビーム他端を到達側岸のエアバッグ橋台２５上に支持させる。これにより架設起点側１と到達側岸２との間に緊急仮設橋としてのエアビーム橋１０を構築する。【選択図】 図１
