The invention discloses a novel anchoring grouting anchor rod and a construction method thereof. The novel anchoring grouting anchor rod is formed by a grouting system, an anchoring system and a fastening system. The grouting system comprises a cover, a vent hole, a grouting hole, a slurry plug, and overflow holes and various parts work together to ensure that slurry is full and tightly bonded. The anchoring system is formed by anchoring holes, a steel strand, a high-strength spring, an anchor claw, a rotating shaft and a steel strand clamp, initial anchoring force can be provided for the anchor rod, the anchor claw has barbs and rotates under the traction of the steel strand and closely attaches to a surrounding rock, and anchor removal is effectively prevented. The fastening system is formed by an anchor rod body, a slurry stop pad, a tray, a washer and a high-strength nut. After the slurry is solidified, the pre-stress can be provided for the grouting anchor to control the deformation of the surrounding rock. According to the invention, an anchor claw rotation design is employed, the anchor claw closely attaches to the surrounding rock, sufficient anchoring force is provided toprevent the anchor removal, and vent holes are set to ensure a pouring effect. The application defect of an existing grouting anchor is solved, and the novel anchoring grouting anchor rod and the construction method have the advantages of anchor removal prevention, high adaptability and good grouting effect.
