Ask for space underground! Nanjing tops the province in many indicators

First in the scale of integrated pipe corridors

First in tunnel length

First in rail transit sharing


The blue paper "Jiangsu Province Underground Space Development Report 2023" was released.Nanjing ranks first in the province in many indicatorsThe

According to the Nanjing "14th Five-Year Plan" for the development and utilization of underground space, the city will add 4 million square meters of underground space development zone capacity each year.At present, the city's underground space scale is about 80 million square meters, the scale of the province's firstThe

Rail share 65.51 TP3T

The Blue Book shows that among the cities in Jiangsu Province that have opened rail transit, Nanjing Metro's public transportation sharing rate has reached 65.5%, ranking first. //
make headway

Metro Line 7 is the first metro line in Nanjing to adopt fully automated driverless technology, starting from Xishanqiao Station and ending at Xianxin Road Station, with a total of 27 stations. The northern section (Mufu West Road Station to Xianxin Road Station) has been opened for operation, and the southern section (Xishanqiao Station to Yingtian Street Station) has been opened for initial operation.All perimeter and main structures have been completed in the middle section, and ancillary structures are under constructionThe

Currently.Nanjing Metro 11 lines built together. Among them, the continuation of eight lines, respectively, Line 3 Phase III, Line 4 Phase II, Line 5, Line 6, Line 7, Line 9 Phase I, Line 10 Phase II and Line 11 Phase I, continue to encrypt the city rail transit network; city lines 3, respectively, Ningma line, Ning Chu line and Ning Yang line, accelerate the construction of "rail on the metropolitan area! The three city lines are Ningma Line, Ning Chu Line and Ning Yang Line, accelerating the construction of "urban circle on the rail".

Tunnel construction province accounted for 33%

The Blue Book shows that a total of 161 tunnels in 13 district cities were completed and opened to traffic, with a total length of about 198.85 kilometers, of which Nanjing accounted for 33%, ranking first in the province.

Jianning West Road crossing the river channel north of Jiangbei New District Xingpu Road and Jiangbei Avenue intersection, along the east side of Xingpu Road to the south across the Jinpu Railway, in the form of a shield tunnel across the Yangtze River to the south bank, along the existing Jianning West Road and finally Jinchuan River before the West Road. The total length of the route is 6.8 kilometers.

As one of the most difficult projects in China for tunneling through the Yangtze River, Jianning West Road Shield Tunnel adopts 2 sets of mud-water balanced shield machines, boring from north to south. At present, the project has realized the tunnel shield double line through.The main line of the river crossing is scheduled to be completed and open to traffic in 2025The

113 kilometers of comprehensive pipeline corridors completed

The Blue Book shows that 321.92 kilometers of underground comprehensive pipeline corridors have been built in Jiangsu Province.The largest is Nanjing, built 102.8 kilometers. At present, the city continues to promote the orderly construction of comprehensive pipeline corridors.About 113 kilometers of integrated pipe corridors have been built, ranking first in the province.

Jiangbei New District Phase I Integrated Tube Corridor

Yanziji section of the comprehensive pipeline corridor south of Shennong Road, north to Jixiang Street, east to the city around the high-speed, a total length of 2300 meters, is the city's "two rings and six shoots" trunk pipeline corridor system, Jiangnan ring trunk pipeline corridor is an important part. CurrentlyHigh-voltage cable routes are in the laying phaseThe 1,180-meter-long first phase of theCurrently the largest cross-section circular pipe jacking project in the countryThe

Urban underground space is an important growth pole for the future development of cities. Nanjing will continue to promote the construction of a high-quality "resilient city" by rationally developing and utilizing urban underground space, integrating the layout of above and below-ground disaster-prevention space, and enhancing the city's ability to withstand risks.
