Abstract

The invention belongs to the technical field of anchoring devices, and particularly relates to a sleeve extrusion type aerofoil-expanded anchor rod. The sleeve extrusion type aerofoil-expanded anchorrod can be recycled and reused. The sleeve extrusion type aerofoil-expanded anchor rod comprises a sleeve 1, a main rod 2, pin shafts 3, baffles 4, airfoil plates 5, nuts 6 and a pressing ring 7. Themain structural points of the sleeve extrusion type aerofoil-expanded anchor rod are that the main rod 2 is placed in the sleeve 1, the side wall of the front part of the main rod 2 is connected withthe airfoil plates 5 through the pin shafts 3, the sleeve 1 is provided with airfoil plate through holes, the pressing ring 7 is arranged at the rear end of the sleeve 1, and the main rod 2 penetratesthrough a central hole of the pressing ring 7; the nuts 6 are arranged at the rear of the pressing ring 7, and external threads 8 matched with the nuts 6 are arranged at the rear end of the main rod;and airfoil plates 5 and the limiting baffles 4 are arranged on the main rod 2 at the front end of the pin shaft 3.

Description

technical field [0001] The invention belongs to the technical field of anchoring devices, and in particular relates to a sleeve-extruding type airfoil-expanding anchor rod. Background technique [0002] After years of development, bolt anchoring technology for reinforcement is widely used in engineering practice, including slope stability, foundation pit reinforcement, and mineral resource mining. Due to the maturity of bolt reinforcement technology, it is favored by engineers and is used more and more in practice. Rock and soil anchoring is to install the anchor rod into the stratum, connect the surrounding unstable rock and soil mass to the stable stratum to form a bearing community, and use the shear strength of the anchor to make the rock mass more stable and not easily destroy. Compared before and after the use of bolt support, the mechanical properties of the soil have been greatly improved, the maintenance cost has been greatly reduced, and economic benefits have be...
