The Mangshan Tunnel on the Jiaozuo-Pingdingshan High-speed Railway officially entered the shield tunneling phase on Friday. To meet the project's key challenges, the China Railway 11th Bureau Group customized the "Jiaoping No.1," an earth pressure balance (EPB) shield machine, for this tunnel. The machine innovatively adopts a combined cutter configuration, which also integrates an intelligent auxiliary tunneling system and a shield big data model, enabling real-time collection of tunneling parameters and automatic adjustment.
The railway is a key component of China's high speed railway network, with a total length of about 230 kilometers and a designed speed of 350 km/h. Located in Luoyang, the Mangshan Tunnel is one of the main projects of the entire line, with a total length of 6,340 meters, of which the shield-driven section is 4,970 meters long and has an excavation diameter of 14.57 meters.
Once completed and opened to traffic, the railway will connect Jiaozuo, Jiyuan, Luoyang and Pingdingshan in Henan, injecting strong impetus into the high-quality development of central China and the comprehensive revitalization of the countryside. (Xinhua/Zhu Xiang)
