[0002] Tunnels are key projects in the construction of roads, railways, and other projects. With the development of railway construction and technological advancements, tunnel excavation methods have developed rapidly. The more commonly used excavation methods include drilling and blasting, shield tunneling, and tunnel boring machine (TBM). Due to its strong adaptability to geological conditions and low excavation costs, drilling and blasting is particularly suitable for the construction of hard rock tunnels, broken rock tunnels, and a large number of short tunnels. Therefore, drilling and blasting is still a commonly used tunnel excavation method both at home and abroad.

[0003] Existing technology, such as the utility model for a tunnel blasting drilling positioning mechanism, with authorization publication number CN221271134U, uses an electric nozzle that can rotate 360 ​​degrees and spray paint on the tunnel wall for marking.
