China's massive tunnel boring machine (TBM) rolled off the production line on Saturday in Changsha City of Hunan Province in central China, ready to be deployed to Hangzhou City of Zhejiang Province in east China to drill a new high-speed railway tunnel.
With an excavation diameter of 14.3 meters, a length of about 126 meters and a total weight of 3,100 tons, the machine is about to drill through a 4,068.7-meter tunnel, including a challenging 3,250-meter stretch of ultra-soft soil.
To handle geological complexities, the machine, named "Linghang" or Piloting, is equipped with advanced navigation system, slurry circulation system, and early warning system for adverse geological conditions.
The Linghang TBM will be used in the construction of the Hangzhou Xiaoshan Airport East High-Speed Railway tunneling project. Once completed, the 85 km railway is to link cities around Hangzhou, and enhance multi-layered transportation networks in the Yangtze River Delta region.

China's development of green industries and the country's initiative of building a unified national market have made steady progress over the first three quarters of 2024, according to the data published by the State Taxation Administration on Sunday.
The tax data highlighted that the development of green industries has gathered pace in Jan-Sept, reflecting a resilient and diversified economic landscape.
Sales revenue in the ecological protection and environmental governance sectors surged by 11.4 percent, while the green technology services sector, including renewable energy and energy-saving solutions, witnessed a growth of approximately 20 percent. As China's broader strategy has continued emphasis on transition toward a more sustainable and innovative paradigm, sales in the clean energy sector, including solar, wind, and hydropower, maintained a rapid growth.
The transportation and logistics sector also registered faster growth, with sales revenue rising by 10 percent year on year. In particular, the growth in multimodal transport and freight forwarding services saw increases of 33.5 percent and 11.3 percent, respectively. The transportation sector in Sept alone experienced a 10.6 percent growth.
Moreover, interprovincial sales volume rose by 2.5 percent, outpacing the overall growth rate of national enterprise sales revenue by 1.1 percent, reflecting a steady progress in building a unified national market.
China on April 10, 2022 unveiled guidelines for accelerating the building of a unified national market, envisioning breaking local protection and market fragmentation and unblocking key sticking points that weigh on economic circulation, as part of a wide-ranging push for an effectively regulated, fairly competitive and fully open market across the country.
