Abstract

The invention discloses a supporting anchor rod capable of slowly releasing preservative liquid. The supporting anchor rod comprises an anchor rod body, a protective shell is fixedly installed at theupper end of the side wall of the anchor rod body, a fixing ring is fixedly installed on the inner wall of the protective shell, a spring is fixedly installed on the lower surface of the fixing ring,a pull ring is fixedly installed on the lower surface of the spring, arc-shaped plates are fixedly installed on the lower surface of the pull ring, a coating bag is fixedly installed on the upper surface of the fixing ring, a connecting rod is fixedly installed at the inner end of the side wall of the coating bag, and the side wall of the lower end of the connecting rod is fixedly connected with the side wall of the anchor rod and on the inner wall of the pull ring. Long-term supplement of anchor rod body coating and short-term rapid extrusion of maintenance coating are achieved, and the purposes of long-term anticorrosive coating maintenance and short-term rapid emergency maintenance of the rod body are facilitated.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a support bolt capable of slowly releasing anticorrosion liquid. Background technique [0002] Anchor rods are widely used in various engineering constructions such as mines, tunnels, and dams. One end of the rod body goes deep into the surrounding rock of the chamber and slope, and the other end is connected to the engineering attachment. Water, salt spray, sulfur dioxide, hydrogen sulfide, and dust are common in the geotechnical engineering environment. During the support and service period, the surface oxide film and anti-corrosion coating of the bolt are damaged by tension, shear and torsion, and the bolt body is directly exposed to the environment. In the process, obvious metal corrosion occurs rapidly, which significantly reduces the mechanical properties of the metal material such as strength, plasticity, and toughness, and causes premature failure of the bolt. Due to the l...
