At present，The foundation works of Xiayan Road Station have been completed.、Construction of earthwork and main structure below the rail bearing layer，Erection for subsequent track beam、Decoration and supporting facilities have created conditions for entry.，The steady progress of the project has laid a solid foundation.。
In the near future，Shanghai Shentie is responsible for investment and construction.、Nanhui Branch Line of Shanghai Regional Railway Constructed by China Railway 14th Bureau（Lianggang Regional Railway）Bid 5 ushered in new progress in construction。Excavation is carried out with four Excavators swinging their arms in the field.，Successful excavation of foundation pit in south area of open-cut section from Dongda Highway Station to Lingang Comprehensive Area Station in Bid 5 of Nanhui Branch Line。This is the first section of Nanhui branch line to excavate the foundation pit.，It marks that the 5th bid project has entered the foundation pit construction stage in an all-round way.。
The total length of the 5th bid project line is about 1264 meters.，The shield section is about 719 meters long.，The open-cut section is about 545m long.，The excavation length of the southern foundation pit is 286..1 meter，31 at the widest point.6 meters，The deepest part of excavation is 18.2 meters，Earthwork volume of foundation pit up to 9.80,000 square meters，The stratum is mainly composed of muddy clay.、Clay, etc，Open excavation and consequent construction method is adopted.。
The total length of Nanhui Branch Line is about 34.86 kilometers，Wherein the main line is about 27.88 kilometers，The east branch line is about 6.98 kilometers，There are 6 stations on the whole line.，The maximum speed of the train is 160 kilometers per hour.。After the completion of the project，It will become the hub of Lingang New Area and Pudong.、A fast link between Hongqiao Hub and the main urban area of Shanghai，As an important support for the radiation of the Yangtze River Delta in the new port-vicinity area.，Help to realize the new port-vicinity area“Connect inside and outside、Land, sea and air linkage”International open hub function。
In the near future，With the last reinforcement cage smoothly into the groove，Shanghai Shentie is responsible for investment and construction.、The construction of 116 underground continuous walls of the enclosure structure of Jinyuan Fifth Road Station of Jiamin Line 11 of Shanghai Regional Railway, which was constructed by the Municipal Group of Tunnel Co., Ltd., has been completed.，Preparations for foundation pit excavation will be started.。
Jinyuan Fifth Road Station is located at the intersection of Cao'an Highway and Lexiu Road in Jiading District.，After completion, it will transfer with Metro Line 14.。The station is an underground three-storey island station.，Including 2 groups of wind pavilions、3 entrances and exits and 2 transfer channels，Excavation depth of foundation pit is 26.5 m to 29.3 meters。
In the near future，Shanghai Shentie is responsible for investment and construction.、Yindu Road Station of Bid 20 of Jiamin Line of Shanghai Regional Railway, constructed by China Railway No.4 Engineering Group Co., Ltd., has entered the stage of comprehensive construction.，At present, 19 pieces of diaphragm wall construction of enclosure structure have been completed.。
Yindu Road Station is located in Humin Highway, Minhang District.，It is an underground two-storey island station.，Total length approx. 829.2 meters，There are 5 entrances and exits and 3 groups of wind pavilions.。There are 314 diaphragm walls in the main enclosure structure of the station.，Among them, there are 77 pieces in Area 1 of this construction.。The first diaphragm wall was successfully inserted into the trench on September 5.。
The length of Jiamin Line is 44.04 kilometers，Passing through Jiading、Minhang 2 Administrative Districts，There are 15 stations on the whole line.，The maximum speed of the train is 160 kilometers per hour.。According to the plan，It is part of the Shanghai regional railway network.，Important north-south main shaft trunk，Jiading New Town is connected in series.、Hongqiao Hub、Main routes of important new towns and transportation hubs such as Minhang，Yeah, too“Yangtze River Delta on the track”An important part of。After the completion of the project，It will realize the interconnection with the airport liaison line.，Greatly alleviate the pressure of Hongqiao hub distribution，It has become a new engine driving the economy of West Shanghai.。Author of Wen Wei Po：Zhang Xiaoming
