China Unveils Largest Self-Developed Tunnel Boring Machine 🚇✨ - 🌍NewspaperAmigo

The Chinese mainland has rolled out its largest self-developed tunnel-boring machine, marking a significant milestone in engineering and infrastructure development.

This impressive machine, capable of excavating tunnels up to 16.64 meters in diameter, was manufactured in Changsha, Hunan Province. It’s a collaborative effort between China Railway Construction Heavy Industry Co., Ltd. (CRCHI) and China Railway 14th Bureau Group Co., Ltd.

Measuring 145 meters in length and weighing approximately 5,000 tonnes, the machine boasts a cutterhead diameter equivalent to a five or six-story building. According to CRCHI chairman Zhao Hui, this achievement highlights China’s advancements in large-diameter tunnel boring technology.

The new tunnel-boring machine is set to play a crucial role in a large-scale tunneling project beneath the Yangtze River. This project will create a major trans-river road link between Nantong and Taicang in Jiangsu Province, enhancing road networks and supporting the integrated development of the Yangtze River Delta.

Once completed, the project is expected to boost regional connectivity and drive economic growth, showcasing the Chinese mainland's commitment to infrastructure innovation and development.
