Launching the Aoqin No.1 shield tunneling machine, the Hengqin extension line project of Macao Light Rapid Transit completed the construction process of an undersea tunnel as on November 25 2022.
The intended project with a total length of 2.2 kilometers, of which about 906 meters are beneath shield tunneling construction, is the first using the shield tunneling method in Macao. Many subsidiaries of CRCC cooperated fully to build the earth pressure balance shield machine Aoqin 1 tailored to the project’s natural geological environment and excavation risk points, in order to ensure the smooth excavation of the shield construction.
Providing more comfortable and convenient travel environment for residents, this project is an important livelihood project for Macau and it helps Macao to be included in the one-hour living circle in the Guangdong-Hong Kong-Macao Greater Bay Area.
