FALL PREVENTION FENCE
To provide a fall prevention fence that is installed on a river or sea embankment and is not likely to be damaged even when it is not removed when water overflows due to heavy rain.SOLUTION: A fall prevention fence 1a includes: a plurality of columns 2 that are installed on an embankment 53 provided along a river 55; a connector 3 that is installed at lower ends of the columns 2; a pair of rod-shaped supports 4, 4 whose upper ends 4a are swingably held by the connector 3; a cart 5 to which a lower end 4b of the support 4 is swingably connected; guide means 6a that swingably holds the support 4; a horizontal hole 7 that is formed inside the embankment 53 and in which the connector 3, the support 4, the cart 5, and the guide means 6a are installed; and a wire that connects upper parts of two adjacent columns 2, 2 to each other. The embankment 53 is provided with a water intake hole 8 for allowing water of the river 55 to flow into the horizontal hole 7, and the cart 5 is installed on an inclined surface 7a provided at the bottom of the horizontal hole 7.SELECTED DRAWING: Figure 1
【課題】河川や海の堤防に設置され、大雨などが発生して越水した場合に撤去しなくとも破損するおそれのない転落防止柵を提供する。【解決手段】転落防止柵１ａは、河川５５に沿って設けられた堤防５３に設置される複数本の支柱２と、支柱２の下端に設置される連結具３と、連結具３によって上端４ａが揺動可能に保持される一対の棒状の支持具４、４と、支持具４の下端４ｂが揺動可能に連結された台車５と、支持具４を揺動可能に保持するガイド手段６ａと、堤防５３の内部に形成され、連結具３、支持具４、台車５及びガイド手段６ａが内部に設置される横穴７と、隣り合う２本の支柱２、２の上部同士を互いに連結するワイヤを備えている。また、堤防５３には、横穴７の内部に河川５５の水を内部へ流入させるための取水孔８が設けられており、台車５は横穴７の底部に設けられた傾斜面７ａに設置されている。【選択図】図１
