[0002] Anchor rods are the most basic component of tunnel support. They reinforce the surrounding rock of the tunnel, allowing the surrounding rock to support itself. Anchor rods are not only used in tunnels, but also in engineering technology: for main reinforcement of slopes, mines, dams, etc. Anchor rods are tensile members that penetrate deep into the stratum. One end of the anchor rod is connected to the engineering structure, and the other end is deep into the stratum. Therefore, during the tunnel construction process, a hole is first drilled inside the tunnel, and then the anchor rod is inserted into the hole. Finally, adhesive is poured into the hole to fix the anchor rod in the hole.

[0003] Since the holes on the tunnel side wall are of different heights from top to bottom, the holes at lower heights can be manually aligned during the anchor bolt installation process. However, the manual alignment error of the holes at higher heights is large during the anchor bolt installation process. If workers use a lift to reach the specified height to align the anchor bolts, the high height of the holes poses a greater threat to the workers' safety, affecting the installation efficiency and safety of the anchor bolts.
