Right-handed Anchor Rod Composition

The composition of an anchor rod must have several factors: ① a rod body with a tensile strength higher than that of the rock and soil mass
② One end of the rod can be in close contact with the rock and soil to form frictional (or bonding) resistance
③ The rod body is located at the other end outside the rock and soil mass, which can form radial resistance to the rock and soil mass
As a tensile component that penetrates into the ground, the anchor rod is connected to the engineering structure at one end and penetrates into the ground at the other end. The entire anchor rod is divided into a free section and an anchoring section. The free section refers to the transmission of tension at the anchor head to the anchor solid area, and its function is to apply pre-stress to the anchor rod; The anchoring section refers to the area where the cement slurry binds the prestressed steel bars to the soil layer. Its function is to increase the bonding friction between the anchor solid and the soil layer, increase the bearing capacity of the anchor solid, and transmit the tensile force of the free section to the depth of the soil.
Based on the above definition, the basic structure of the anchor rod is given.
