SLOPE STABILIZING METHOD DOUBLING AS DEBRIS FALL PREVENTING METHOD, SLOPE STABILIZING-CUM-DEBRIS FALL PREVENTING STRUCTURE, AND JOINT STRUCTURE FOR USE THEREIN

摘要

PROBLEM TO BE SOLVED: To achieve the stabilization of a natural slope and to prevent a debris fall with high efficiency and good workability without damaging the natural landscape. SOLUTION: There is provided a slope stabilizing method according to which a number of anchors 1 are driven into the natural slope, and bearing members 2 are attached and fastened to respective anchor heads to apply a bearing force to the ground, the anchors 1 are connected to each other by ropes 3, to thereby stabilize the slope. A large triangular mesh (major triangle 5) is defined by the ropes (major ropes 3) which connect the anchors 1, and a debris fall preventive net 10 having fine meshes formed of other ropes (subordinate ropes 6) is formed in the large mesh. Thus the fine meshes of the debris fall preventive net 10 formed of the subordinate ropes 6 function to press fragmented rocks and bounding stones, to thereby prevent the debris fall. In this manner, measures against the debris fall can be flexibly taken only for necessary areas depending on circumstances of the site, whereby effective measures against the debris fall are implemented.
