[0030] In the utility model, Figure 4 As shown, the device body 1 is in a state of being installed inside the reservoir slope, and the device body 1 has completed grouting. At this time, the moving support rod 4 is lowered to tighten the anti-slip flip plate 3 outward, so that the upper end of the anti-slip flip plate 3 is inserted into the inner wall of the reservoir slope installation hole, thereby preventing the cylindrical reinforcement rod 2 from slipping out upward during grouting.
