BRIDGE GIRDER FLOATING DEVICE
To provide a bridge girder floating device capable of being easily mounted to an existing bridge and preventing a bridge girder from being buried in a river bed.SOLUTION: A bridge girder floating device is installed in a bridge girder 11 of a bridge 1 bridged over a river R. Further, buoyancy bodies 2, 2 having an average density smaller than that of water fixed to side surfaces 111, 111 of the bridge girder are provided. Furthermore, a protective plate 3 is attached to a corner part on the downstream side of a bridge pier 12 on which the bridge girder is mounted. And the bridge girder is connected to the bridge pier through a mooring material 4 of a length which does not come into contact with the bridge pier when the bridge girder is contact with the riverbed R1 of the river.SELECTED DRAWING: Figure 1
【課題】既存の橋梁に対しても簡単に取り付けられるうえに、橋桁が河床に埋まることを防ぐことができる橋桁浮上装置を提供する。【解決手段】河川Ｒに架け渡される橋梁１の橋桁１１に設けられる橋桁浮上装置である。そして、橋桁の側面１１１，１１１に固定される水よりも平均密度が小さい浮力体２，２を備えている。さらに、橋桁が載せられる橋脚１２の下流側の隅角部に防護板３が取り付けられる。また、橋桁は、河川の河床Ｒ１に橋桁が着底したときに橋脚と接触することがない長さの係留材４を介して橋脚と連結されている。【選択図】図１
