The construction site of Jiajian Highway Station is narrow, the working space is limited, the geographical environment is complex, and the underground soil types are diverse. The east side is adjacent to the high-voltage line, and the west side is adjacent to the municipal road, which has extremely high requirements for on-site safety management. In order to ensure the smooth progress of construction, the project team has prepared a special construction plan in advance and invited experts for review, strictly implementing various safety and quality control requirements, and strengthening safety management from strict to detailed to practical.

Opening and hoisting of the ground connected wall. Underground continuous wall is a type of excavation machinery used in foundation engineering on the ground. Along the peripheral axis of the deep excavation project, a narrow and long deep groove is excavated under the condition of mud wall protection. After cleaning the groove, steel cages are hung inside the groove, and then underwater concrete is poured using the conduit method to build a unit groove section. This is done step by step, and a continuous reinforced concrete wall is built underground as a water interception, anti-seepage, load-bearing, and water retaining structure.

Jiajian Highway Station is located on the south side of the intersection of Chengliu Middle Road and Jiajian Highway, arranged in a north-south direction along Chengliu Middle Road and passing through Yecheng Road. It is an underground two-story island style station with 4 entrances and 2 sets of wind pavilions, with a total length of about 281.2 meters. Jiajian Highway Station is adjacent to multiple residential areas, and the completion of the project will help improve the convenience of travel for surrounding residents.

"Finally, I can take a break. Five liters of water is not enough to drink for half a day." Due to the narrow construction environment on site and the adjacent residential areas, the welding and lifting of the ground to wall need to be completed in one go during the effective construction time during the day. After the work is completed, the clothes on Hu Dingqiang, a construction worker from China Construction Eighth Bureau, have been soaked in sweat, and the large water bottle on his back has also been emptied.

It is reported that the Jiamin Line has a total length of 44.04 kilometers and passes through two administrative regions, Jiading and Minhang. There are a total of 15 stations along the line, and the maximum operating speed of trains is 160 kilometers per hour. According to the plan, it is an important north-south main trunk line in the Shanghai urban railway network, connecting important new cities and transportation hubs such as Jiading New City, Hongqiao Hub, and Minhang. It is also an important component of the "Yangtze River Delta on the track". After the project is completed, it will achieve interconnectivity with the airport connecting line, greatly alleviating the pressure of distribution at the Hongqiao hub and becoming a new engine for driving the economy of West Shanghai.
