High-speed railway

Focusing on the currently commonly used methods for mountain tunnel excavation, including the three-arm drilling jumbo method, the multi-functional tunneling machine method, and the manual pneumatic drilling method, this study takes the excavation of a single face of a double-track railway tunnel

In this paper, the mechanized construction technology for high-speed railway tunnel is comprehensively analyzed. Through the introduction of advanced mechanical equipment and technology, such as full computer three-arm drilling rig, long-span telescopic mobile treble, etc., multiple improvements
