CIHT Hong Kong is excited to offer this joint technical visit with HKIE. Join us to hear from Ir. KM Chiang, General Manager of the Shanghai Tunnel Engineering Co., LTD and Mr Zhu Kung, Chief Engineer, CCCC.
Macau Light Rail Transit (LRT) East Line South Section
The full 7.7 km LRT East Line stretches from the Border Gate to Taipa, comprising viaducts, tunnels, six underground stations, and a railway system. The LRT East Line is a vital infrastructure project supporting Macau’s border connectivity, urban development, and integrated transport network. The total length of the Southern Section of the East Line is approximately 4.7 km, involving the construction of 3 new stations named ES4, ES5, and ES6, using the cut-and-cover method. The project commences from ES4 station heading south to ES5 station, traverses through a 12.1m diameter subsea long tunnel to reach ES6 station, and then connects via a viaduct to the Taipa Ferry Terminal station.
In response to the complex geology and construction challenges of the Macau LRT East Line's subsea tunnel (minimum turning radius of 450 meters, composite strata, high seabed pressure), the "澳氹1号" tunnel boring machine (TBM) underwent key technical upgrades - Adaptive Tunnelling System: Equipped with axis adaptive technology to achieve millimeter-level error control and autonomous tunnelling; and Geological Adaptability Technology: Technologies such as intelligent cutterhead monitoring, excavation chamber monitoring, and retractable drives to enhance the TBM's adaptability during tunnelling.
Zhuhai Xingye Expressway (Southern Section) Lot 2 Project
The Zhuhai Xingye Expressway is an urban expressway with a design speed of 60km/h and a total length of approximately 23.59 kilometers. It serves as a core longitudinal corridor within Zhuhai City's "Nine Vertical, Five Horizontal" road network. More importantly, it is a critical project linking Zhuhai with the Greater Bay Area, acting as a vital connecting corridor for the Hong Kong-Zhuhai-Macao Bridge and the Shenzhen-Zhongshan Bridge. Upon completion, the project will promote the coordinated development of five cities—Hong Kong, Macau, Zhuhai, Zhongshan, and Shenzhen—and strengthen transportation links and economic exchanges among Greater Bay Area cities.
The main line of the project is 2,320m long, of which the shield tunnel section is 1,739m long. The Tunnel Boring Machine (TBM) diameter for the main line shield is 15.76m, constructed using a slurry pressure balance shield machine. The TBM diameter for the Z2 ramp shield is 11.71m. This project represents China's first case of super-large diameter stacked shield tunnels. The lower 15.76m main line tunnel and the upper 11.73m ramp tunnel overlap for a length of 604m, with a net vertical clearance of only 7.5m. The total distance for the two shield drives is 2,234 meters, which is one of the challenging projects in construction industry.
