At present, three-arm rock drilling rigs are often used during tunnel construction in my country. Due to the complex geological conditions of the surrounding rock at the construction site, and full-section construction is not carried out, the construction effect can be improved by supporting fully

In order to apply mechanized drilling and blasting method for large-section tunnel construction in weak surrounding rocks， construction technologies of rock drilling and arch installation were studied based on Laifu tunnel of Chongqing-Kunming high speed railway. Through the renovation of the

Drill boom is the positioning and support of drilling, and its performance directly affects the efficiency and quality of drilling. Once the boom stops working, the entire drilling operation cannot be completed. The failure of the drill boom is analyzed and the troubleshooting method is introduced.

Based on the research on the cost and influencing factors of the three-arm rock drilling rig in expressway tunnel engineering, the article mainly focuses on the project overview, the basic parameters and applicability of the three-arm rock drilling rig, and the use of the three-arm rock drilling
