industrial north express road in Ji'nan road design for the first time reserved deep underground and underground space. Ji'nan Municipal Design Institute of municipal design
4 days, Qilu Evening News reporter learned from the Ji'nan municipal municipal public bureau news conference, the industrial North Expressway in the premise of not affecting the premise of traffic, the construction, recently will start all over. The full line design of the industrial North Expressway opens the veil. The designers introduce that the rail transit, BRT and bus will achieve zero transfer along the project, and the underground space is stratified for the first time, and the depth and space of the rain are reserved. In addition, the main roads and branches along the project will be synchronized and will combine with the construction of sponge city to alleviate the problem of waterlogging along the line.

Expressway
4 lanes of
Industrial North Expressway will be started in the near future. According to the staff of the Municipal Public Bureau, all the construction units entered the field in July 16th. On the basis of the completion of the work of Surveying and mapping, the foundation of the pipeline and other work, the first pile foundation has been put into construction in July 30th. The construction units will be formally entered into the Construction recently.
Industrial North Expressway from the west to the North Garden Avenue all luck interchange, east to the bypass city high speed east line Guodian interchange, a total length of about 13.6 kilometers, the total investment of about 6 billion 400 million yuan. The expressway works in the Ji'nan expressway project at the latest. The construction of the elevated section is the longest and the underground complex pipe gallery is the largest. Xiu Chunhai, deputy director of the Ji'nan municipal public service, said that the project will shorten the 3 - year period of the original viaduct and ground plan by the end of 2017 by the end of the second ring expressway network established by the city of Ji'nan, which will be completed by the main project at the end of next year.
interval of 1.5 km ramp
build 3 overpass
Industrial North Expressway along the way to synchronize construction of ground roads. 4 cross river bridges will be built along the line. The elevated part of the project has two way six lanes with a design speed of 80km/h and a ramp for a single lane, designed for 40km/h. The ground road is two-way eight lanes, the design speed is 50km/h, the inside is BRT lane. At the same time, the intersection width and bus bay are considered on the basis of the standard section.
will be along the road west of the road to the east of the chemical fiber plant road, the west of the Austrian Road, the east of the Austrian Road, the west of the Phoenix Road, the east of the industrial South Road, the 8 pairs of ramp symmetrically near the west of Fengming road and the ramp of Guo Dian interchange. The average distance between the ramp is 1500 meters, the landing point of the ramp is more than 150 meters from the ground road intersection, and the upper ramp of the west side of Fenghuang road is to avoid the conflict with the railway station, and the distance to the intersection is about 70 meters. The location of the 3 pedestrian overpasses along the
is the first to be published in the vicinity of happy willow square, Hengda city and Wang Ru people street. East part of the flyover will demolish part of the existing bridge, build a new elevated whole, and set up a pair of parallel ramps to the west of the electric road junction. Reserve the status of the status of the Guodian interchange, the viaduct to the west main line of the city to the ground, in order to ensure smooth traffic and import and export of the store, set up a pair of upper and lower ramp directly with the Guodian interchange and exit ramp.
from rail transit station
can directly transfer bicycle
industrial north express road and rail transit R3 line between happy Liulu road to dam King Road between about 4.5 kilometers, the track traffic line is mainly in the north half of the fast lane. In the Austrian Middle Road, cold water junction, R3 line industrial North Road station, Wang Chai man station and BRT platform, Olympic Middle Road station, cold water road station met. Wang Ping introduced that rail transit, bus rapid transit and conventional public transport system will be seamless in the two sites, while slow traffic and public transport will also be seamless. Although it is a different transportation system, at these two sites, the public can have the experience of zero transfer.
design map shows that after the arrival of the two stations by the BRT car, the citizens do not need the BRT platform. The BRT platform in the middle of the road can be directly down to the ground and go to the R3 line platform to take the subway. In addition, the subway station can also be transferred from the underground passage to the ground to transfer to the common bus or bicycle. Besides, the bicycle parking lot is also designed beside the common bus stop of the road intersection. The 4 modes of transportation will be able to truly achieve zero transfer.
the design of underground drainage deep
Industrial North Expressway has been designed from 2012. According to the experience of urban road construction at home and abroad in recent years, the design concept of the expressway is more advanced. In addition to the expressway and ground roads, the underground space is layered.
nearly 20 meters from ground to underground is shallow underground space, laying directly buried pipelines and comprehensive pipe corridors. Further down is the deep underground space. At present, the track R3 line is in the deep underground space. In addition, the underground and deep drainage tunnel spaces were reserved for the first time in the southern deep underground space.
these two reserved spaces, the construction of the expressway is not built. In the future, according to the development needs of the surrounding cities, once the road space is insufficient, we can use the shield method to build two-way four lane tunnels.
in addition, the industrial north road is located in the low-lying area of northern Ji'nan. The road construction has already taken into account the problem of water accumulation. Once there is drainage problem in the future, the drainage tunnel space with a diameter of 8 meters can be set up in the deep underground space. Because the underground space is lower than the ground, drainage or upgrading needs to be discharged later.
Xiu Chunhai said that the deep underground construction in Ji'nan is the first time. At present, the construction of Singapore has been carried out, and the domestic city of Guangzhou has also been built. But whether or not to build in the future needs to be determined according to the needs of urban development.
