Abstract

The invention discloses a high-strength anchor rod. The high-strength anchor rod comprises an anchor rod body, wherein a drill bit is arranged on one end of the anchor rod body and is fixedly connected with the anchor rod body, a square nut, an arched cushion plate and a slurry blocking plug are sequentially arranged on the other end of the anchor rod body from left to right, the arched cushion plate is fixedly connected with the slurry blocking plug, the arched cushion plate and the slurry blocking plug are fixedly connected with the anchor rod body, and the square nut is connected with the anchor rod body through threads; and a first steel bar, a second steel bar, a third steel bar and a fourth steel bar which are used for reinforcing the anchor rod body are arranged on the arched cushion plate, are distributed in an annular array manner, are fixedly connected with the arched cushion plate and penetrate through the slurry blocking plug. According to the high-strength anchor rod, thestrength can be effectively improved.

Description

technical field [0001] The invention relates to a high-strength anchor rod. Background technique [0002] The bolt is the most basic part of roadway support in contemporary coal mines. It reinforces the surrounding rock of the roadway so that the surrounding rock can support itself. Now anchor rods are not only used in mines, but also in engineering technology for main body reinforcement of slopes, tunnels and dams. As a tensile member that goes deep into the ground, the bolt is connected to the engineering structure at one end, and the other end goes deep into the ground. The whole bolt is divided into a free section and an anchor section. area, whose function is to apply prestress to the anchor. [0003] However, the strength of existing anchor rods is poor, and those skilled in the art hope to provide a high-strength anchor rod that can effectively improve strength. Contents of the invention [0004] The technical problem to be solved by the present invention is to p...
