Multiple stations in Beijing Metro Line 19 Create rail transit micro -center

Last weekend, with the four new stations of Jingfengmen, Taiping Bridge, Ping Anli, and Beipingzhuang, the first phase of Metro Line 19 was opened to traffic. The reporter learned from the Railway company affiliated to Beijing yesterday that among the 10 stations of Line 19, Xintong Station, Jingfengmen Station, and Mudan Garden Station were included in Beijing's first batch of rail transit. Key projects for urban renewal. In terms of operation service, all stations in Line 19 are all equipped with AED devices.

In the center of the rail transit, the traffic space refers to the "third living space" of the citizens in addition to families and units, and the regional public living room. Lu Qingquan, deputy minister of the survey and design headquarters of Beijing Investment Corporation, introduced that at present, the integrated rail transit project in Beijing is mainly divided into three categories in accordance with the combination of the subway: auxiliary combination and channel connection, comprehensive utilization and functional weaving supplements Essence

Take Line 19, for example, the integrated design that focuses on the complex of the auxiliary is mainly reflected in the Taiping Bridge Station. The northeast exit, the southeast mouth, the barrier -free elevator, the safety mouth, the air duct and other facilities are combined with the Xicheng District. The integrated combination of Southwest Exit and Unicom's communication production building project. The integrated design that focuses on the connection between the channel is reflected in the west side of the Jishui Tan Station and the underground connection of Xinhua Department Store.

The comprehensive utilization class refers to the construction land around the station, which can be constructed simultaneously with the subway station to achieve convenient transportation, integration of functional landscapes, and saving land. New Palace Station combines the surrounding traffic connection, the status conditions of the venue, and the needs of the community to form a underground street network by adjusting the layout of the station. It also achieves a slow -moving system that integrates the green belt through various landscapes.

The functional weaving category is reflected in Ping Anli Station and Jingfengmen Station of Line 19. Combined with the outside of the station and the entrance and exit of the station, the public service function is set up to set up community service centers to provide residents with convenient and comfortable urban life.

In December 2020, the city released the first batch of 71 micro -center lists of rail transit. The currently built on the 3rd, line 3, Line 12, Line 16, Line 17, Line 22, Line 28, No. 13, 13, 13 The line expansion improvement project and the Changping line south extension project have launched an integrated design of different scope and different degrees.

In the subsequent lines, a number of stations such as Sanyuan Bridge, Lize Terminal, and Dongba Vehicle Base will be promoted to achieve closely connecting and organic integration of rail field stations with surrounding land use planning and construction.

Nearly 11 meters deep! Special first -level risk construction exceeds the sum of 6 lines

Many citizens admire the high value of the new station on Line 19, but they do not know that this line is defined by experts in the construction field as "the difficulty of construction is rare at home and abroad, the construction period is difficult to control, and the risk is difficult to control."

Line 19 crosses the core area of ​​the city. There are many important buildings along the ground and underground, and at the same time, the conditions of geological and groundwater are extremely complicated. According to Lu Qingquan, the initial design plan of Line 19 has an average of 33 meters buried in the line, nearly 11 meters deeper than the previous construction line of the Beijing Metro. Traditional construction methods and means cannot cope with the various constructions brought by the strata and groundwater in this line. problem.

The first phase of Line 19 is only 20.9 kilometers, but the total number of special first -level risk projects exceeds the sum of the six subway lines that have been completed in the second phase of the Beijing Metro. The risk of engineering construction is evident.

"When the traditional construction method is not spiritual, the technical route is not good, and the difficulty of overcome difficulties must rely on engineering technology innovation." Lu Qingquan introduced that more than 20 practical new patent technologies in the participating unit 19 were used. Innovation supports line construction.

Taking Ping Anli Station as an example, the construction conditions of the station are complicated, and there are many environmental sensitive factors such as hospitals, cultural relics, and schools. They do not have the conditions for clear excavation construction. Dark excavation method is the only choice. If the conventional dark digging method is designed, the base base will enter the groundwater exceeding 13 meters, but the ground does not implement the conditions for precipitation operations. Therefore, the conventional dark excavation solution cannot be implemented, and the road to technological innovation must be taken.

According to incomplete statistics, as of the completion and acceptance of Ping Anli Station, a total of more than 30 experts related to innovation have been carried out, 5 patented technologies were formed, and more than 16 special design were carried out, forming 5 domestic first technologies.

At the same time, through innovation, the project's investment in projects was 456 million yuan, and more than 74 million cubic meters of groundwater resources were protected. The total water volume was equivalent to 5 West Lakes. In addition, it has reduced the generation of construction waste about 3,000 cubic meters. (Source: Beijing Daily)
