Plan for 2004
In December 2004, the National Development and Reform Commission issued the"
National highway network planning
(2004) No. 3057). The National Highway Network Plan was approved by The State Council on December 17, 2004
[25]
This is the first "ultimate" highway skeleton layout in Chinese history, and it is also the highest level of highway passage in China's highway network.
The "National Highway network Planning" adopts the layout scheme of radiation and vertical and horizontal grid, forming a large channel from the central city to radiate out and across the east and west, and across the north and south, consisting of 7 capital radiation, 9 north-south longitudinal lines and 18 east-west horizontal lines, referred to as the "7918 network", with a total scale of about 85,000 kilometers, including: The main line is 68,000 kilometers, and other routes such as regional ring lines and liaison lines are about 17,000 kilometers.
Article 6 of the 7 Capital radiation describes Beijing - Urumqi. According to the attached "National Highway Network Layout Plan", its main control points are: Beijing, Zhangjiakou, Jining, Hohhot, Baotou, Linhe, Ejin Banner, Hami, Turpan, Urumqi.
[26]
On July 3, 2007, the Ministry of Communications of the People's Republic of China issued the "National Highway Network Naming and Numbering Rules" (JTG A03-2007) industry standard, which stipulates the naming rules, numbering rules, full name, abbreviation and numbering of national highway network routes. Beijing-urumqi Expressway number: G7, referred to as: Beijing-New Expressway.
[27]

Difficulty in construction
With the gradual increase of the scale of highway construction in mountainous areas in China, the number of large section and long span tunnels has gradually increased, and the construction of such projects is difficult and the safety risk is high. The Jinpenwan Tunnel of the Beijing-new expressway constructed by CCCC is a long tunnel with a large section of the whole Ⅴ class soft surrounding rock, due to
Project scale
Large, poor geological conditions and difficult holes, the project was rated as "Highway bridge and tunnel engineering construction safety risk assessment pilot project" by the Ministry of Transport, the overall risk level of construction safety was rated as level IV (extremely high risk), and the construction difficulty was identified as the third in the country.
During the construction process of increasing construction space by the method of middle septum in half section, cracks, falling blocks, arch deformation, invert bottom heave, roof collapse and other diseases often occur after the initial support construction of the tunnel is completed. When the tunnel goes deeper into the deep buried section, excessive settlement occurs more frequently, resulting in arch change danger caused by arch deformation, which aggravates the construction safety risk and affects the construction period. The simple middle septum method (CD method) and three steps method in the original design can not meet the construction requirements.
solution
The construction side attaches great importance to the construction of Jinpenwan Tunnel, comprehensively tracks the tunnel construction problems from the early stage of construction, and carries out special project research on the excavation method selection optimization of the whole Ⅴ class surrounding rock tunnel with large section, and the initial support large deformation control measures, and has achieved fruitful results.
After comparing and optimizing the middle septum method, middle septum three-step method, three-step method, half-section middle septum method and other excavation methods, and passing the expert demonstration for many times, the project department optimized the middle septum method (CD method). According to the characteristics of different surrounding rocks of the tunnel, the half-section middle septum method and double-layer initial support method were combined with the three-step method, and mechanical excavation was cited. The construction safety is guaranteed and the construction progress is accelerated.
In order to avoid the construction risk of the middle septum method (CD method) more effectively, the large section of the upper half section of the tunnel is divided into two small sections through the middle septum to reduce the excavation section and ensure the stability of the upper section during excavation. In the construction of the lower half section, the step method is used to speed up the construction progress of the lower half section and make the supporting structure closed into a ring as soon as possible. By reducing the excavation area of the upper section, the working space of the lower section is increased, and mechanical construction is introduced to improve the efficiency.
According to reports, the limitation of the half-section middle door method is that the stability is relatively reduced before the entire section supporting structure is not closed, and the surrounding rock is applicable to the construction conditions without excessive settlement and convergence.
As the shallow buried section deepens to the deep buried section, abnormal excessive settlement and convergence frequently occur in the tunnel excavation process. After taking various measures such as increasing the anchor pipe of the lock foot, increasing the reserved deformation, welding the steel reinforcement on the arch frame, and shortening the safety step distance, the project department finally adopted the construction method combining the initial support of the double-layer steel arch frame with the three-step method. The settlement and convergence of the tunnel are well controlled, and the thickness of the secondary lining is ensured by resisting the cracking of the primary branch and the deformation of the arch.
The double-layer initial support is applied by three-step method, and the milling machine is used during excavation to reduce the disturbance to surrounding rock. During construction, the left and right middle guide, lower guide and invert are excavated alternately. Finally, the invert is closed into a ring with the outer steel support, and the two sides of the same section are jointly stressed to avoid being empty at the same time.
The combination of double-layer initial support method and three-step method can fundamentally restrain the initial support settlement, effectively control the deformation of large-section tunnel, and avoid the high-risk operation risk of arch replacement after single arch deformation.
Since then, the Jinpenwan Tunnel has been using the double-layer initial support construction method, no encroachment, arch change phenomenon, the monthly progress reached 55-60 meters, the left hole has been successfully through

Beijing-new Expressway traverses Northeast China, North China and Northwest China, also known as the "Three North Grand Highway", with a total length of about 2,739 kilometers, it is one of the seven Beijing radiation lines in the National Highway Network Planning. It is the most convenient road channel between Northwest Xinjiang and Hexi Corridor connecting the capital Beijing, North China, Northeast China and the eastern part of the mainland, and also a new land channel out of Xinjiang. It shortens the length of the road from Xinjiang to Beijing by more than 1,000 kilometers, which can significantly save transportation costs

.
Beijing-new Expressway is an important part of the national expressway network. To a certain extent, it diverts vehicles from western provinces and regions to Beijing, effectively alleviates the traffic pressure of Beijing-Tibet Expressway, and has significant social benefits

In November 2022, it was selected into the final list of "China's Top 100 Buildings in the New Era 2022".
