Background Art
[0002] Anchoring technology is to fix one end of a tension rod in the rock or soil layer of the slope or foundation. The fixed end of the tension rod is called the anchor end (or anchor section); the other end is connected to the engineering building, which can withstand the thrust applied to the building by soil pressure, water pressure or internal force, and use the anchoring force of the stratum to maintain the stability of the building. Therefore, the end anchoring operation of the anchor rod steel bar is very important. At present, the conventional anchoring process in engineering is to insert the anchor rod steel bar into the slope soil layer, and then weld the end of the steel bar to form an anchor section. Such an anchor section is only subjected to unidirectional force, and it is often difficult to ensure the welding quality on site, resulting in low construction efficiency. Summary of the invention
