What is the route of Beijing Line 4 subway?

Metro Line 4 is a subway line invested, constructed and operated by Beijing Infrastructure Investment Co., Ltd. (BII), Beijing Capital Venture Group Co., Ltd. (BCG) and Hong Kong Metro Company in a franchise mode, which is called PPP mode. The franchise is 30 years, and the total investment of the project is about 654.38+053 billion yuan, of which 70% is contributed by Beijing Municipal Government and 30% by Beijing Jinggang Metro Co., Ltd., a franchise company.

Metro Line 4 is a rail transit trunk line running through the north and south of Beijing's road traffic network. The total length of Line 4 is 28.2km, and there are 24 stations and transfer stations 10 along the line, which are mainly concentrated in the urban center. Line 4 passes through densely populated Fengtai, Xuanwu, Xicheng and Haidian administrative districts, and passes through large residential areas and science and education areas with strong academic culture (Tsinghua, Peking University, National People's Congress, etc.). ) and the high-tech park known as "China Silicon Valley" (.

At 9: 58 this morning, the shield section of "Beigongmen-Beilongcun" of Beijing Metro Line 4, which was built by China Railway No.1 Bureau Group, was accurately and safely connected at a distance of more than ten meters from the Beigongmen of the Summer Palace, which marked the completion of Beijing Metro Line 4, and Line 4 became the first subway line in Beijing in 2009. Metro Line 4 is expected to open in September 2009.

It is reported that the shield section from Beigongmen to Beilong Village is 506 meters long, and the maximum longitudinal slope of the line is 4.535%. , the minimum line spacing is 1 1m and the minimum curve radius is 350m. Earth pressure balance shield machine is used in the construction. The tunnel is a single-hole circular tunnel with an outer diameter of 6 meters and an inner diameter of 5.4 meters. Most tunnels pass through silty clay, silty sand, silty soil, sandy pebble layer and most strongly weathered rocks. Above the tunnel floor, it passes through the ancient city walls and scenic spots of the earth-rock structure of the Summer Palace in Qing Dynasty, as well as dozens of houses without infrastructure construction. The underground tunnel passes through rainwater, sewage, gas, telecommunication pipelines and communication cables for 22 times, which is one of the major risk sources of Beijing subway construction.

In view of the complicated and changeable geological survey, the shield machine operators strengthen the monitoring frequency according to the stratum conditions, and take turns to be on duty at the ground site 24 hours a day to ensure zero settlement of the ground houses. It overcomes many difficulties such as underground water sac, cavity, quicksand, ground traffic vibration, tight construction period, small site and complex stratum.
