The second set of shields of Jiangnan Shipbuilding (Group) was completed.
The second set of the "Shanghai Chongsu" shield tunneling machine, featuring a diameter of 15.43 meters, was successfully manufactured by Jiangnan Shipbuilding (Group) Co., Ltd. on February 13. The installation process was carefully monitored and remained within the required standards. The project owner has already submitted the test results for review. Recently, the casing components were dismantled and transported to Shanghai Tunnel Company for further assembly and use in upcoming underground projects. This development marks another milestone in China's growing expertise in large-scale tunneling technology, showcasing the country's advanced engineering capabilities and commitment to infrastructure innovation. The successful completion of this project also highlights the collaboration between shipbuilding and tunneling industries, reinforcing the importance of cross-sector cooperation in modern construction. As the next phase of the project moves forward, engineers and project managers are expected to closely monitor the performance of the shield machine to ensure optimal efficiency and safety during tunnel excavation.
