ROCK BOLT DISPLACEMENT DETECTION TOOL AND SLOPE STABILIZATION METHOD USING THE DISPLACEMENT DETECTION TOOL
To provide the invention related to a rock bolt displacement detection tool for detecting a sign of collapse of a slope of a mountain caused by an earthquake, rainfall, or the like and a slope stabilization method, and to provide a displacement detection tool enabling visual observation of a deformed state such as collapse of a slope caused by an earthquake or rainfall by improving a wire binding method.SOLUTION: There are provided a rock bolt displacement detection tool and a slope stabilization method using the displacement detection tool. Four rock bolts 1 (1a to 1d) are installed on a slope G in a quadrangular shape and a wire 2 is wound around the rock bolts to form a quadrangular frame R. Portions of the wire 2, which are located on a lower side of the quadrangular frame R and are close to both terminals of the wire, are arranged in two rows, are fitted into a recessed groove 4, and are held via a holding tool 3. Then, the wire terminals protruding from the holding tool are fixed using fastening members 6. Displacement detection materials 7 are fitted between the holding tool 3 and the fastening members 6 to form a quadrangular frame unit A. A number of quadrangular frame units are connected and arranged in a zigzag form and are laid.SELECTED DRAWING: Figure 1
【課題】地震や降雨などによる山の斜面崩壊の予兆を捉えるロックボルトの変位検知具及び斜面安定化工法に関し、ワイヤーの緊結方法を改良して地震や降雨によって発生する斜面の崩落等の変状を目視できる変位検知具を提供する。【解決手段】ロックボルトの変位検知具及びこれを用いた斜面安定工法において、斜面Ｇに４本のロックボルト１（１ａ〜１ｄ）を四角形に打設し、ロックボルトにワイヤー２を巻き掛けて四角形枠Ｒを成形すると共に、四角形枠Ｒの下辺に位置するワイヤー２の両端末の付近を２列に並べて凹溝４に装着して挟持具３を介して挟持すると共に、挟持具から突出しているワイヤー端末をカシメ部材６で固定し、挟持具３とカシメ部材６の間に変位検知材７を装着して四角形枠ユニットＡを成形し、これを多数千鳥配置に連結して敷設する。【選択図】図１
