The invention relates to the technical field of construction tools and discloses a reinforcing anchor rod for
tunnel construction. The reinforcing anchor rod comprises a rod body, one side of the rodbody is fixedly connected with one side of each
metal sheet and in
insertion connection with one side of a slide sleeve, and the inner wall of the slide sleeve is in sleeve connection with the surfaceof a slide rod. One side of the slide rod is fixedly connected with one side of a retaining block, the top of the slide rod is fixedly connected with the bottom of each first oblique block, the top of each first oblique block is in
lap joint with the bottom of a second oblique block, and the top of each second oblique block is fixedly connected with the bottom of a moving rod. The reinforcing anchor rod for
tunnel construction has advantages that by reinforcing rods fixedly connected to the surface of the rod body, the
metal sheets fixedly connected to one side of the rod body, a rotating rod, a
threaded rod, a threaded sleeve, a pull rod, the slide rod, the retaining block, the first oblique blocks, the second oblique blocks, the moving rods, fixing sleeves and sharp blocks, when the threaded sleeve moves, the retaining block pushes the
metal sheets to warp to increase the anchoring force, and then the sharp blocks are inserted into soil to enhance the anchoring force of the anchor rod.
