CRUSHED STONE SPLASH PREVENTION MATERIAL
To provide a crushed stone splash prevention material that is light-weight, enables itself to be folded in a predetermined direction, makes it easy to visually recognize a state of crushed stones when the material is set, and may enhance efficiency of crushed stone removal and recovery work.SOLUTION: A crushed stone splash prevention material for covering crushed stones laid along a track rail is a net-like body consisting of a plurality of synthetic resin wires. A plurality of twisted parts are formed by twisting together the plurality of synthetic resin wires along a predetermined first direction. The respective twisted parts are formed along the first direction so as to be separated from one another.SELECTED DRAWING: Figure 1
【課題】軽量であり、それ自体を所定方向に折り畳むことができ、かつ、設置された際に砕石の状態を視認しやすく、砕石の撤去や復旧作業効率を高め得る砕石飛散防止材を提供すること。【解決手段】軌道レールに沿って敷設される砕石を覆う砕石飛散防止材であり、複数の合成樹脂製線材からなる網状体であり、前記複数の合成樹脂製線材を所定の第１方向に沿ってねじり合わせることにより、複数のねじり合わせ部が形成され、それぞれの前記ねじり合わせ部は、前記第１方向に沿って互いに離間して形成される、砕石飛散防止材。【選択図】図１
