PROBLEM TO BE SOLVED: To provide an inexpensive slope face reinforcement method capable of preventing surface layer slide-down of a slope face caused by heavy rain and an earthquake.SOLUTION: In a slope face slide-down prevention method by a constitution of a vegetation mat body, an anchor and a wire, the vegetation mat body 2 is arranged in a zigzag shape between timbers 1 growing on the slope face, and is fixed by a plurality of L-shaped anchor pins 3, and an anchor of the length of 1-1.5 meters (a reinforcement being an irregular shape reinforcement in which all knots of the surface have a screw shape and which is easily joinable by the principle of a screw by using a nut and a joint) is also placed in a central part of the vegetation mat body by using the joint with a blade up to a foundation layer of the natural ground. A plate 6 formed with a locking part in the four corners is fastened-fixed to an upper part of the anchor by a washer and a lock nut 8, a wire 9 is tensioned in the locking part of the mutual plates formed on the respective vegetation mats, and the wire is tightly tensioned by a turnbuckle 11.
【課題】豪雨や地震等による法面の表層滑落を防止することができる安価な法面補強方法を提供する。【解決手段】法面に成育する立木１間に植生マット体２を千鳥足状に配置して複数本のＬ型アンカーピン３にて固定し、更に該植生マット体の中心部に長さ１〜１．５メートルのアンカー（表面のフシが全ネジ状の異形鉄筋でナットや継手を使ってネジの原理で手軽に接合できる鉄筋）を地山の基礎層まで羽根付継手を用いて打設する。該アンカーの上部に四つ角に係止部が形成されたプレート６をワッシャーとロックナット８にて締付固定し、各植生マットに形成されたプレート同士の係止部にワイヤー９を張りターンバックル１１でワイヤーを張り詰め、植生マット体と該アンカーとワイヤーの構成による法面の滑落防止工法。【選択図】図１
