Vietnam's neighbor breaks record, shows off 3,500-ton "machine king"

On March 26, in Hunan, China, the Qiangji TBM tunnel boring machine was officially launched, marking an important step forward for the country's construction machinery industry. (Photo: China Daily)

Qiangji is 107 meters long, 12.68 meters in diameter and weighs up to 3,500 tons, becoming the world's largest diameter double-shell TBM. (Photo: Xinhuanet)

The giant machine was built to participate in the Hangzhou West Lake drainage expansion project – the largest urban drainage project in China. (Photo: Xinhuanet)

China used to have no TBM technology, but now owns about 5,000 machines, accounting for 70% of the global market share and building more than 90% of the subway tunnels in the country. (Photo: CafeF)

To cope with Hangzhou's complex geology, Qiangji is equipped with "double shield - earth pressure shield" technology, which can effectively penetrate alternating hard and soft soil layers. (Photo: enghunan.gov.cn)

Qiangji's intelligent tunneling system allows real-time monitoring of more than 20 parameters, optimizing millimeter-level precision during construction. (Photo: enghunan.gov.cn)

Digital twin technology helps visualize the entire tunneling process, helping contractors closely control construction quality. (Photo: enghunan.gov.cn)

When completed, this drainage system will help reduce flood control for the Taihu Lake basin, ensure urban safety, and create a protective shield for the center of Hangzhou city against natural disasters. (Photo: Hi-Tech Mail)
