Anchor support is a reinforcement support method used in surface engineering such as slopes and deep rock and soil foundation pits, as well as underground bunker construction such as tunnels and mining sites. Rods are made of metal, wood, and polymer parts, and driven into pre-drilled holes in the surface rock or the rock around the bunker. The surrounding rock and the stable rock are combined together by the special structure of the head and rod body and the tail support plate, or by relying on the bonding effect to produce a suspension effect, a composite beam effect, and a reinforcement effect to achieve the purpose of support. It has the advantages of low cost, good support effect, simple operation, flexible use, and less construction clearance.
