New progress has been made in the construction of Line 21! These two stations have entered the excavation stage of the foundation pit
Recently, the Yanggao North Road Station and Kangnan Road Station of Line 21 Phase I project have successively entered the excavation stage of the foundation pit, laying the foundation for the construction of the main structure of the station. At present, out of the 18 stations in the first phase of Line 21, 11 stations have started construction.
Yanggao North Road Station is located on the east side of the intersection of Jufeng Road and Yanggao North Road, arranged in a north-south direction along the green belt on the east side of Yanggao North Road, and connected to Yanggao North Road Station on Line 12 for transfer. The station is an underground three story island style station. The total length of the main body of the station is 170 meters, with a standard section width of 21.6 meters and a standard section foundation pit depth of approximately 28.2 meters.
The excavation depth of Yanggao North Road Station on Line 21, along with numerous surrounding structures and pipelines, poses extremely high requirements for safe and civilized construction and risk management. The Fourth Branch of Shentong Metro Construction Group requires participating units to layout in advance, make reasonable arrangements, and implement reinforcement measures before the excavation of the foundation pit, striving to ensure that there is no leakage in the ground wall during the excavation stage. At the same time, strengthen the inspection work during the process, conduct regular and fixed-point inspections on the excavation surface, and carry out real-time information monitoring.

Kangnan Road Station is an underground two-story island type station, which adopts a double column and three span cast-in-place reinforced concrete box structure. The total construction area of the station is 27006 square meters. The foundation pit adopts an underground continuous wall with internal support enclosure scheme, and the construction is carried out through open excavation method. The excavation of the first zone foundation pit has laid a solid foundation for the subsequent reconstruction of the main structure.
The first phase of Metro Line 21 has a total length of about 28 kilometers and 18 stations. The route passes through Chuansha New Town, Kangqiao Town, Zhangjiang Town, Jinqiao Town, and Gaoxing Town from south to north, connecting important areas such as the International Tourism Resort, Zhangjiang Science City, and Jinqiao City Sub Center.
After the completion of the project, it will provide better public transportation facilities and services for residents along the route, promote the development of key areas, and improve the efficiency and quality of travel along the route. Especially in promoting the coordinated development of the three functional zones in Pudong New Area, Shanghai, supporting the full play of the functions of the two main and sub centers, and promoting the construction of Shanghai as a globally influential science and technology innovation center, it plays an important role.
