Description

Anti-corrosion anchor rod of mining large-deformation roadway Technical Field The utility model relates to the field of anchor rods, in particular to an anti-corrosion anchor rod of a mining large-deformation roadway. Background The anchor rod is the most basic component part of roadway support in contemporary coal mines, and the anchor rod reinforces surrounding rocks of the roadway together so that the surrounding rocks support themselves. The anchor rod is not only used for mines, but also used for engineering technology, and is used for reinforcing main bodies of slopes, tunnels and dam bodies. The anchor rod is used as a tension member penetrating into the stratum, one end of the anchor rod is connected with an engineering structure, the other end of the anchor rod penetrates into the stratum, the whole anchor rod is divided into a free section and an anchoring section, the free section is the area that transmits the pulling force at the head of the bolt to the anchor body, whose function is to pre-stress the bolt. However, the existing anchor rod is poor in structural strength and corrosion resistance, so that the anchor rod is easy to damage, and the service life of the anchor rod is further influenced. In order to solve the problems, an anti-corrosion anchor rod of a mining large-deformation roadway is provided.
