Description

Technical Field

[0001] The present application relates to the technical field of rock and soil anchoring, and in particular to a rock and soil anchoring structure. Background Art

[0002] Anchoring refers to the process of wrapping steel bars in concrete to enhance the bond between concrete and steel bars, making the anchorage object stronger, so that the two can work together to withstand the pressure, tension, bending moment, torque, etc. generated by various loads. The location and form of anchoring can be in the form of hooks, bends, etc., and can also refer to the length of the steel bar anchored into the component. If there is not enough anchoring length, the force on the steel bar cannot be effectively transmitted to the anchor body. In order to ensure the force transmission effect of the steel bar, the relevant specifications stipulate that the anchoring length should not be less than 200m.

[0003] Anchor rods are the most basic component of tunnel support in contemporary coal mines. They reinforce the surrounding rock of the tunnel so that the surrounding rock can support itself. Now anchor rods are not only used in mines, but also in engineering technology to reinforce slopes, tunnels, and dam bodies. As one of the main support forms for underground projects and rock slopes, anchor rods play an important role in maintaining the stability of civil engineering, especially in jointed and fissured rock masses. The reinforcing effect of anchor rods on rock masses is very obvious. At present, the anchor heads of geotechnical anchor rods are mostly fixed, which is inconvenient to disassemble and replace the anchor heads. The strength of the anchor rods is insufficient, which affects the stability of geotechnical anchoring. Therefore, in order to solve the above problems, we provide a geotechnical anchoring structure.
