Slope stabilization method using rock bolt displacement detector and its displacement detector

摘要

PROBLEM TO BE SOLVED: To improve a wire binding method for a rock bolt displacement detector and a slope stabilization method for catching a sign of a mountain slope collapse due to an earthquake or rainfall, and to improve a deformation such as a slope collapse caused by an earthquake or rainfall. Provide a displacement detector that can visually check. SOLUTION: In a displacement detector for lock bolts and a slope stabilizing method using the same, four lock bolts 1 (1a to 1d) are driven into a quadrangle on a slope G, and a wire 2 is wound around the lock bolts. Along with forming the quadrangular frame R, the vicinity of both terminals of the wires 2 located on the lower side of the quadrangular frame R are arranged in two rows and mounted in the concave groove 4 to be sandwiched through the sandwiching tool 3 and protruding from the sandwiching tool. The wire terminal is fixed by the caulking member 6, the displacement detecting member 7 is attached between the holding tool 3 and the caulking member 6, the quadrangular frame unit A is formed, and the quadrangular frame unit A is connected and laid in a staggered arrangement.
