railway tunnel Key Techniques and Equipments for Mechanized Construction of Drilling and Blasting Tunnel in Weak Surrounding Rock 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
tunnel engineering Application of Fully Computerized Three-arm Rock Drilling Rig and Intelligent Arch-anchor Integrated Rig in Extra-long Highway Tunnels With the rapid development of the transportation industry, the national highway network continues to expand to remote mountainous areas in the southwest. The number of highway projects in mountainous areas is also increasing year by year, and the proportion of extra-long tunnels is increasing.
rock drilling rig Analysis and Troubleshooting of Drill Boom Faults of Rock Drilling Rig 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.
