         Hollow anchor rod is a slender rod body that penetrates deep into the interior of rock and soil and controls the deformation of the rock and soil. The accessories include a cushion plate Nuts and other
components. One end is connected to the engineering structure, and the other end penetrates deep into the bottom layer. The entire anchor rod is divided into free sections The free section refers to the section that transfers the tension at the anchor head to the anchor solid area, and its function is to apply pre tension to the anchor rod Stress; The anchoring section refers to the area where the cement slurry binds the prestressed reinforcement to the soil layer, and its function is to connect the anchor solid with the soil The adhesive friction effect of the layer increases, increasing the pressure bearing effect of the anchor body, and transmitting the tension of the free section to the depth of the soil.
