Research on the Application of Three-Arm Rock Drilling Trolley in Tunnel Excavation
This paper mainly studies the application of three-arm rock drilling trolley in tunnel excavation.Firstly,the basic structure and working principle of the three-arm drilling rig are described.Secondly,its role and advantages in tunnel excavation construction are discussed.Finally,combined with the construction process of tunnel excavation,from the aspects of face design and hole layout optimization,equipment installation,debugging and positioning,and selection of drilling process parameters,the application points of three-arm drilling rig in tunnel excavation are expounded.The research shows that the three-arm drilling rig can significantly improve the tunneling efficiency,improve the working environment,and promote the development of mechanization and automation of tunnel engineering.
