Description

Technical Field

[0001] The invention relates to the technical field of mine construction, and in particular to an anchor support device with good ductility for mine construction. Background Art

[0002] Anchor rods are the most basic component of tunnel support in modern coal mines. They reinforce the surrounding rock of the tunnel so that the surrounding rock can support itself. Anchor rods are not only used in mines, but also in engineering technology to reinforce the main body of slopes, tunnels, and dams. As a tensile member that penetrates deep into the stratum, one end of the anchor rod is connected to the engineering structure, and the other end penetrates deep into the stratum. The entire anchor rod is divided into a free section and an anchoring section. The free section refers to the area where the tension at the anchor rod head is transmitted to the anchor body. Its function is to apply prestress to the anchor rod.

[0003] Existing anchor rods are generally fixed by grouting or using the principle of expansion bolts. Grouting requires waiting for the grouting to solidify before it can play the effect of anchor support, while expansion bolts cannot be recycled after fixing, and the expansion diameter is limited, resulting in poor fixing effect in areas with slightly larger holes.
