New progress has been made in the construction of the Jiading section of the Jiamin Line of the Municipal Railway. The reporter learned from the construction party, Shanghai Shentie, that the foundation pit floor of the 5th area of the 11th standard Jinyuan 5th Road Station of the Jiamin Line was successfully poured, which also marked the completion of the first stage of the foundation pit excavation construction of the station and was about to enter the construction stage of the main structure of the station.
11 Biaojinyuan No. 5 Road Station is located at the intersection of Cao'an Highway and Lexiu Road in Jiading District, which is a three-storey underground island station with a total length of 250 meters. The excavation depth of the foundation pit of the main body of the station is between 26.5 meters and 29.3 meters.
Due to the proximity of the station to Lexiu Road Station of Rail Transit Line 14, in order to ensure that the foundation pit construction does not affect the normal operation of the rail transit, the project team set up 4 sealing walls in the foundation pit, divided 5 independent foundation pit areas, and adopted a jump excavation process to further reduce the impact of the size effect of the foundation pit.
According to reports, the 1st, 3rd and 5th districts under construction are the main structure of the first phase of the station. At present, the concrete pouring of the side wall of the negative second floor is being carried out in Zone 1, and the reinforcement binding of the side wall of the negative second floor is being carried out in Zone 3.
The Jiamin Line is 44.04 kilometers long, passing through the two administrative districts of Jiading and Minhang, with a total of 15 stations and a maximum speed of 160 kilometers. According to the plan, it is an important north-south main axis trunk line in Shanghai's regional railway network, the main line connecting Jiading New Town, Hongqiao Hub, Minhang and other regional and transportation hubs, and an important part of the "Yangtze River Delta on the track". After the completion of the project, it will realize the interconnection with the airport liaison line, greatly alleviate the pressure of Hongqiao hub distribution, and become a new engine to stimulate the economy of West Shanghai.
