When the hollow anchor rod is inserted into the inside of the slope, the utility model inserts the conduit into the inside of the hollow anchor rod, so that the conduit extrudes the radial limiting rod, the radial limiting rod moves to the outside of the hollow anchor rod through the side hole and is inserted into the slope, thereby fixing the hollow anchor rod, preventing the hollow anchor rod from loosening and falling off in the hole drilled in the slope when the conduit is pulled out, and improving the stability during installation of the anchor rod and the installation efficiency of the anchor rod.

[0004] In the actual construction process, when the anchor rod is used for rock layer, the drilling and anchor rod insertion are difficult due to high hardness of the rock, and in this case, the rotation speed is lower, generally 30-60 revolutions per minute; however, when the anchor rod is used for soft soil (such as silt, silty clay, etc.) texture layer, the resistance to insertion of the anchor rod is small due to the relatively soft soil, in order to ensure that the anchor rod can be smoothly inserted without damaging the soil structure, the rotation speed of the drill for inserting the anchor rod is generally 80-120 revolutions per minute, however, when the slope anchoring device in the prior art is used for soft soil texture layer, the hollow anchor rod is connected to the drill and inserted into the slope body, the drill rotates to insert the hollow anchor rod, and the centrifugal force generated during the rotation of the hollow anchor rod may extrude the spring of the radial limiting rod and make the radial limiting rod slide out of the side hole, thereby affecting the rotation insertion of the hollow anchor rod and affecting the progress of slope protection work.
