Embodiment Construction
[0018] refer to figure 1 Further illustrate method steps of the present invention:
[0019] The first step: level the surface of the rock mass at the required experimental site, and the leveling range should be larger than the area of the bearing plate;
[0020] Step 2: Drill a hole at the center of the experimental point and install the anchor rod 2. A certain length of non-anchor section 6 is left during installation. The length of the non-anchor section 6 is greater than or equal to twice the diameter of the bearing plate; at this time, the anchor The length of the rod 2 should be the length of the non-anchor section 6 plus the length of the anchor section 7; the anchor rod can be mechanically anchored, resin anchored or cement mortar anchored, etc.;
[0021] The third step: fill the surface of the flattened rock mass with mortar, and place the bearing plate 1 with a central hole, and the diameter of the central hole is greater than the diameter of the anchor rod 2;
