STONE FALL PREVENTION FENCE
PROBLEM TO BE SOLVED: To provide a stone fall prevention fence capable of surely checking falling to the mountain side of a column, and capable of also freely adjusting an inclination angle of the column, even when a valley side wire for checking falling-in to the mountain side of the column cannot be stretched, without requiring to provide a support column for checking the falling-in to the mountain side of the column.SOLUTION: A stone fall prevention fence comprises a column 2 constructed at a predetermined interval on a slope face 2, a mountain side wire 5 stretched between an upper end part of the column 2 and the slope face 2 of the mountain side (M), a wire net 6 stretched between the columns 1 and receiving a stone fall and a connection member 7 composed of an expandable turnbuckle fixed between the column 1 and the slope face 2 of the valley side (V).SELECTED DRAWING: Figure 1
【課題】支柱の山側への倒れ込みを阻止する支持柱を設ける必要がなく、しかも、支柱の山側への倒れ込みを阻止する谷側ワイヤーが張れない場合であっても、支柱の山側への倒れを確実に阻止することができ、さらに、支柱の傾斜角度を自在に調整することができる落石防止柵を提供することにある。【解決手段】斜面２に所定間隔をあけて構築される支柱２と、支柱２の上端部と山側（Ｍ）の斜面２との間に張られる山側ワイヤー５と、支柱１間に張られた、落石を受け止める金網６と、支柱１と谷側（Ｖ）の斜面２との間に固定される伸縮可能なターンバックルからなる連結部材７とを備えている。【選択図】図１
