Line 5 is a north-south diameter line running through the old city in the planning of rail transit network. It's a skeleton line. The line is located on the east side of the central axis of the city, connecting Fengtai, Dongcheng, Chaoyang and Changping in the north-south direction. It is connected to the center of the main city and the edge of Beiyuan in the north, serves the Asian Games Village, Dongdan Street in Wangfujing business district in the center of the old city in the middle, and serves the large residential area in Qianzhuang in the south.
There are 13 transfer stations on the whole line. Among them, 10 station will transfer to stations with completed lines, namely Chongwenmen Station, Yonghegong Station and Line 2; Transfer between dongdan station and 1 line; Lishuiqiao Station Transfer to 13 Line; Transfer to the south exit station of Huixin West Street and Songjiazhuang Station 10 line; Transfer between Songjiazhuang Station and Yizhuang Line; Transfer to Line 6 at Dongsi Station; Ciqikou Station and Line 7 transfer; Transfer between Puhuangyu Station and 14 line; Transfer between Datun Road East Station and 15 line. There are also three stations to transfer to the planned line. There are four tie lines on the whole line, of which the tie line with line 1 is located in the southwest of dongdan station. Set the northwest azimuth connection 13 line of Lishuiqiao Station; The interface with line 10 is set in the southeast of the south exit station of Huixin West Street; The southeast of Ciqikou Station is provided with a connecting line interface with Line 7; To the southwest of Datun Road East Station, it is planned to connect with 15 line. 1.5 line has an extremely important historical position in the history of national subway construction, and it is a model project with demonstration significance. It is an important milestone in the construction of Beijing rail transit. It is the first rail transit artery running through the north-south direction of Beijing, which greatly shortens the travel time of residents along the line, reduces the pressure of ground traffic and saves energy. At the same time, it has greatly promoted the economic development along the route, showing an amazing "subway effect."
The opening of Line 2.5 gives people a new understanding of rail transit. As a new starting point of Beijing rail transit, Line 5 is not only the image project of Beijing rail transit, but also an important part of the Olympic project. As the overall design unit of the project, in the planning and design work of 15, we have been carrying out the spirit of the instructions of the leaders of the municipal party committee, the municipal government and relevant ministries and commissions that "the new subway should fully embody the people-oriented characteristics and conform to the level of a modern metropolis", and under the guidance of the overall principle of "safety, function, humanization and internationalization", we are striving to build a high-level, full-functional, safe and fast subway for the citizens.
Since 5438+ 10 was put into operation in June, 2007, the line structure is stable, the equipment is in good running condition, it meets the design and use functions, and the quality has always been rated as excellent. It has changed people's way of life and travel-effectively relieved the situation of traffic congestion on the ground, promoted the economic development along the route, adapted to the development needs of Beijing as a modern international metropolis, and made important contributions to "New Beijing, Great Olympics".
The opening of Line 3.5 has raised the national and local governments' awareness of the importance and urgency of rail transit construction to a new height.
The "subway craze" immediately after the opening of Line 5 and the "subway effect" along the line have strengthened the determination of the government and relevant departments to develop urban underground rail transit. At the same time, more than 20 cities across the country have planned to build rail transit.
As the earliest London subway in the world, the total construction time span is 408 kilometers-as long as 140 years. Up to the opening of Line 5, there are 17 1.6km subway lines in Beijing. By 20 15, the total length of Beijing planned subway will reach 56 1.5km, and the construction scale and speed are amazing.
4. Accelerating the pace of Beijing subway construction has played an exemplary role.
For the first time, Line 5 established a unified standard for subway design, construction, risk assessment and acceptance. Line 5 has changed the situation that there were only scattered standards for subway construction in Beijing in the past, and formed a complete system of technical standards, acceptance standards, risk assessment system and construction monitoring system for the first time, which laid a valuable technical foundation for the new line construction. It has played an exemplary role in standardizing the subway construction in Beijing and even the whole country, improving the engineering quality and speeding up the construction pace. The design of Line 5 fully embodies the new concept of "people-oriented, scientific and technological innovation" in rail transit, boldly adopts many new technologies and processes, and creates a number of "firsts" in the field of rail transit construction, such as:
Shield method was successfully applied in Beijing subway for the first time;
For the first time, it was successfully implemented in Beijing to build a new station through underground excavation while maintaining the operation of the existing subway structure;
The Integrated Equipment Monitoring System (ISCS) was first implemented in Beijing Metro. Passenger information service system (PIS), security door system (PSD);
The concept of rail transit network command center is put forward for the first time. The concept of "double center" of AFC network clearing center (ACC) and its implementation;
The first application of contactless IC card tickets:
Steel-aluminum composite rail is adopted for the first time;
For the first time, the guiding signs are systematically adopted, and the whole process is humanized and barrier-free;
Curved cable-stayed bridge with double-sided cables is adopted for the first time on the subway line;
For the first time, the guiding document "Technical Requirements for Preliminary Design of Beijing Metro Line 5" was compiled.
Many modern technologies and processes have been reasonably used, showing a brand-new image of rail transit engineering; With elegant, atmospheric, continuous and modern station decoration style, it has created a unique subway cultural space in Beijing and continued the image of Beijing subway. The high-quality completion of the design task of Line 5 is the result of team efforts. The project passes through the bustling downtown area of Beijing, and the traffic on the main roads on the ground cannot be interrupted. There are many underground pipelines and underground excavation stations, and many places pass through existing subway lines, municipal bridges, dangerous houses and cultural relics protection units. The design difficulty of this project is the highest in the history of China rail transit construction. Many unprecedented technical problems need to be coordinated and solved by design.
Faced with these problems, several chief designers of the General Design Institute led the whole design team, withstood the pressure, brainstormed, carried forward the team spirit and worked together, and finally all the problems were solved one by one.
