“山河号”超大直径盾构机
China's home-grown super-large-diameter mixshield machine "Shanhe" rolled off the production line in Jinan, capital of East China's Shandong province, on May 19.
5月19日，由济南重工集团、海瑞克集团联合济南城市建设集团、中铁十四局集团研发制造的“山河号”超大直径盾构机在济南顺利下线。
With a diameter of 17.5 meters, the machine is set to be utilized in the construction of a tunnel project on Huanggang Road in Jinan, which is the world's largest diameter tunnel currently under construction.
这台“山河号”泥水平衡盾构机，最大开挖直径17.5米，将应用于济南市黄岗路穿黄隧道工程，这是目前世界在建最大直径盾构隧道，为济南“携河北跨”再添新通道。
With a total length of 163 meters, a weight of approximately 5,200 metric tons, and a total installed power of 12,580 kilowatts, the machine features a pressurized composite cutter head, retractable main drive, and slurry chamber with a retractable camera.
该盾构机总长163米、重约5200吨、装机总功率12580千瓦；装配带压复合型刀盘、伸缩式主驱动、泥水仓伸缩摄像头等。
It allows for the automatic monitoring of cutter head wear and real-time equipment status monitoring and features an intelligent equipment system. Furthermore, remote operation is facilitated through the big tunnel cloud intelligence platform to ensure safe and efficient tunneling.
该盾构机还搭载刀盘磨损自动监测、设备状态在线监测和“五官一脑”智能化装备系统，并通过大盾构云智慧平台实现远程操控，以保证掘进安全和效率。
The Huanggang Road tunnel project involves traversing through a complex geological environment comprising full-section silty clay, calcareous nodules, and cemented sand layers. The tunnel's deepest overburden thickness is 49.2 meters, with a maximum water and soil pressure of 6.3 bars (equivalent to bearing a weight of 6.3 kilograms concentrated on the area of a fingernail). These challenging conditions necessitate exceptional performance from the machine.
济南市黄岗路穿黄隧道工程长距离穿越全断面粉质黏土、钙质结核、胶结砂层等复杂地质，最深覆土厚度达49.2米，最大水土压力6.3巴（相当于指甲盖大小面积上承受6.3公斤的重量），对盾构机的性能提出了极高要求。
The tunnel project is a key component in establishing a major north-south passage across the Yellow River. Once completed, it will facilitate seamless connectivity between Jinan's main urban area and the Jinan Start-up Area for Growth Drivers Transformation.
济南黄岗路穿黄隧道工程是构建南北向跨黄河的大通道之一，建成后，将助力济南主城区与新旧动能转换起步区互联互通，有力推进起步区建设全面提速。
