During tunneling construction, the tunnel surrounding rock is disturbed by human and overlying rock stress, and its internal primary joints and fissures develop and expand, resulting in criss-crossing cracks of varying sizes, which reduce the stability of the tunnel surrounding rock and bring potential safety hazards to construction safety. Grouting reinforcement is required to improve the strength of the tunnel surrounding rock and avoid roof safety accidents that may harm construction personnel and delay the progress of the project. When grouting reinforcement is performed on the surrounding rock cracks, it is necessary to construct grouting holes in the surrounding rock so that the slurry can be injected into the surrounding rock cracks.
