High-speed railway

Using the Yubai Tunnel on the Hamu high-speed railway as a case study, this paper looks at full-section tunnel construction in weak surrounding rock. By optimizing drilling and blasting techniques, applying guided fracture controlled blasting, improving shotcrete quality, and reasonably adjusting

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
