Slope reinforcing method

The invention discloses a slope reinforcing method which comprises the following steps: (1) firstly, vertically drilling a vertical hole downwards from the top of a slope at a position far away from the slope surface; (2) placing a reinforcement cage for reinforcement into the vertical hole; (3) a row of anchor rods corresponding to the vertical holes are hit inwards from the slope surface, and in the process, a special tool and a measuring technology are utilized to ensure that the row of anchor rods and the vertical holes are located on the same plane, so that all the anchor rods in the row are inserted into or penetrate through the vertical holes and the reinforcement cage from the side surfaces; (4) blocking the opening of the anchor rod on the slope surface; (5) pressurizing and injecting concrete inwards from the upper part of the vertical hole, and enabling the concrete to extend and flow along the penetrating path of the anchor rod while filling the vertical hole, so as to wrap the anchor rod and part
