A worker from China Railway 11th Bureau Group crosses the track in the underground tunnel of the Longzhen Exit and Entry Line in Guangzhou, South China's Guangdong province, June 26, 2020. The tunnel behind him is extremely curved. Workers from the China Railway 11th Bureau Group tunneled through 541.6 meters over a month using a shield construction method at Longzhen Exit and Entry Line of Guangzhou Subway Line 18. The curvature and longitudinal slope of the section are close to the limit of design, making it difficult to shield. It is the stumbling block of Guangzhou Subway Line 18. Guangzhou Subway Line 18 is a major infrastructure construction project in the Guangdong-Hong Kong-Macao Greater Bay Area, connecting the downtown area of Guangzhou with the Nansha Free Trade Zone, with a design speed of 160 kilometers per hour.[Photo/Xinhua]
