BRIDGE UNDERSURFACE WORK METHOD AND POLE FOR BRIDGE UNDERSURFACE WORK
PROBLEM TO BE SOLVED: To provide means for stretching a linear body, which serves as a foothold for inspection and work, across an undersurface of a bridge built in such a place that ground surface conditions are bad as in the case where a bridge undersurface position is too high or where a scaffold cannot be erected, without use of a large-scale apparatus and the like.SOLUTION: A pole for assisting bridge undersurface work, which comprises a pole and a first balloon fixed to the pole and filled with gas lighter than air, is used as a pole for assisting work for a bridge undersurface. Preferably, the pole has a length equal in dimension to or greater in dimension than a width in a width direction perpendicular to an axial direction of a bridge.SELECTED DRAWING: Figure 1
【課題】橋梁下面の位置が高すぎたり、足場を組めなかったりするような地面の状況がわるいような場所に架けられた橋梁の下面に対して、大掛かりな装置等を用いることなく、点検や作業の足掛かりとなる線状体を渡す手段を提供する【解決手段】橋梁下面に対する作業を補助するための竿であって、竿と、竿に固定された空気より軽い気体を充填された第一の気球とを備える橋梁下面作業用竿を用いる。竿は、好ましくは橋梁の軸方向に垂直な幅方向の巾以上の長さを有する。【選択図】図１
