Harbin Metro Line 2 Phase I Final Tunnel Excavation
Original title: The last tunnel excavation of the first phase of the Metro Line 2 will be completed in March next year.
The "Endeavour II" shield aircraft departed from the first phase of the Metro Line 2 engineering meteorological station to Nanzhi Road Station.
On the morning of the 27th, the "Endeavour 2" shield aircraft originated from the first phase of the engineering meteorological station of the Metro Line 2 and digged to the end of the Nanzhi Road Station. This is the last originated shield machine for the first phase of the Metro Line 2 project. At this point, all 22 shields of the project were down the well, and all tunnels entered the excavation phase. It is expected that in March next year, the first phase of the 28.6 km subway line 2 will achieve Dongtong.
The Meteorological Observatory Station is the terminal of the south bank of the Songhua River on the first phase of the Metro Line 2. So far, the station has completed 80 % of the main construction, and it is expected that the main station will be completed in July. As the starting station for shield construction, the "Endeavour No. 1" shield machine carried out shield construction in the well last September. After reaching the Nanzhi Road Station, it completed a one-way tunnel of about 2.7 kilometers. Yesterday, the "Endeavour No. 2" shield under the well shield will be dug in the same direction as "Endeavour No. 1" and proceed to the South straight road station. It is expected that in March next year, the first phase of the Metro Line 2 project will achieve Dongtong.
According to the staff of the Metro Group, the first phase of the Metro Line 2 project passes through the five administrative regions of Hulan, Songbei, Daoli, Nangang and Xiangfang, connecting Harbin Railway Station, Jiangbei Highway Passenger Terminal, Nangang Highway Passenger Terminal, and Sun Island Scenic Area, as well as commercial areas such as Central Street and Hongbo Business District. It is the basic bone trunk line from the north to the southeast of the city.In the future, the project will also transfer with Metro Lines 1, 3, 4, 5, 6 and 8.
The first phase of the Metro Line 2 project has 19 stations across the board. At present, the main structure of 11 stations has been capped, and the remaining stations are planned to be completed this year. According to the plan, the project will be commissioned for trial operation in 2020.
