Beijing Metro Line 17 "Ten Pan Division" on the right line through

Recently, with the slowly breaking out of the "Early Heart" shield machine, the Shilihe-Panjiayuan west section of Beijing Metro Line 17 was successfully connected.

Line 17 starts from the North District Station of Future Science City in the north, and to Jiahui Lake Station in the south. The 13 standard section of the 13th bidding section of the Municipal Company of the 18th Bureau of China Railway was 3.27 kilometers, including one stop and two stations. The total length of the interval is 5.74 kilometers, and the total length of the shield section is 5.19 kilometers.

The "Ten Pan Division" shield section of the "Ten Pan Division" this time is 1225 meters. It is wearing multiple urban roads. The buildings are intensive along the line. There is also a 140 -meter interval and the left -line shield tunnel vertically. The minimum vertical net distance is only 2 meters, and the receiving end is only 25 meters from the existing subway line. The southern section is connected, the safety risks are high, and the construction is difficult.

The project team scientifically compiles the construction plan, relying on real -time information monitoring technology, strictly controls various excavation parameters. In response to the problem of stacking sections, planning ahead, reinforcing the interval structure in advance to ensure the safety of shields.

Line 17, as the underground arteries that run in Beijing in the north and south, will become the "Quick Direct Line" connecting the central urban area and the future science city and Yizhuang after completion. convenient. (Source: Beijing Daily)
