Reinforcing anchor rod for tunnel construction

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of construction tools, in particular to a reinforced anchor rod for tunnel construction. Background technique [0002] Tunnel construction is the abbreviation of the new Austrian tunnel construction method. It is a reasonable construction method proposed by Austrian scholars from the perspective of rock mechanics in the long-term tunnel construction practice. It uses spray anchor technology, monitoring measurement, etc. It is a new engineering construction method formed by a system formed with the theory of rock mechanics. The anchor rod is an indispensable and important tool in the tunnel construction process; most of the existing anchor rods are put into the drill No. No. 1 holes are filled with cement for anchoring. Although such anchors can play an anchoring role, the anchoring force is not very strong, so a reinforced anchor for tunnel construction with strong anchoring force is needed. Contents of th...

[0002] Tunnel construction is the abbreviation of the new Austrian tunnel construction method. It is a reasonable construction method proposed by Austrian scholars from the perspective of rock mechanics in the long-term tunnel construction practice. It uses spray-anchor technology, monitoring and measurement, etc. It is a new engineering construction method formed by a system formed with the theory of rock mechanics. The anchor rod is an indispensable and important tool in the tunnel construction process; most of the existing anchor rods are put into the drill The cement is poured into the hole of No. 10000 for anchoring. Although such an anchor can play an anchoring role, the anchoring force is not very strong, so a reinforced anchor for tunnel construction with strong anchoring force is needed.
