Continuous Belt Mucking Technology of China Railway Tunnel Construction

Abstract

The conventional mucking system of tunnel construction in China has a series of deficiencies and stubborn problems. Tunnel mucking technologies matched with different tunnel construction methods have been analyzed systematically and the continuous belt mucking methodology which is appropriated with drilling-blasting method was presented. The continuous belt mucking technology includes mucking scheme design and mucking equipment configuration. Compared with the conventional mucking methods, the comprehensive benefit can be fully demonstrated by the new continuous belt mucking system. On the other hand, the predominance on environmental protection of the continuous belt mucking technoloty matches up with the conservation policy. The technology would be widely applied in long tunnels and tunnels embedded in frozen ground and located in bitter cold plateau. The economic benifis and contribution to society of continuous belt mucking technology would be remarkable.

“…Song and Xia's innovative carbon emission model, rooted in life-cycle assessment and the carbon emission factor method, offers a nuanced perspective on the environmental footprint of tunneling mechanisms 17 . Sun et al's insights into tunnel slag discharge techniques, especially their proposal of a continuous band slag discharge method, underscore the potential benefits of modern slag extraction systems, especially in challenging terrains like frozen soils and plateaus 18 .…”
