The middle section of Metro Line 7 has now completed track laying and cold and hot slip tests, and is carrying out access commissioning with the north and south ends, with all stations at the stage of electromechanical installation and decoration.
The Caochangmen Station and Qingliangshan Station in the middle section of Line 7 are featured stations, which not only overcome construction difficulties but also closely integrate with the surrounding culture to create an underground "art space".
Caochangmen Station
Simulated star tops "glistening"
Simulate a starry sky roof for an industrial vintage look.At Caochangmen Station, the ceiling of the station hall and platform level is a blue square simulating the starry sky, as if the stars are all over the night sky, creating a glittering visual effect. The wall decorative panels are installed with finished cement decorative panels, and the orange mosaic decorations on the columns create an industrial retro style.
3 interchange points for quick and easy interchange.Caochangmen Station, which interchanges with the existing Line 4, will have three interchange points. "We have set up interchange points in the location of the station hall, platforms and entrances and exits, so that the public will not have to climb up and down after the opening of the station, and there will be a variety of ways to transfer." The project site manager introduced.
Qingliangshan Station
The wall on the 7th basement level is "like a dragon."
New technology of aluminum wall panels, "concave" three-dimensional shape.Qingliangshan station hall level, a piece of diamond-shaped bronze-colored aluminum plate inlaid with the ceiling and both sides of the wall, forming a huge arch like a dragon, the view is very shocking. The person in charge of the scene, the station's design draws on Sun Quan in the stone mountain (today's Qingliangshan area) to build a city and build the capital of the historical allusion, bronze-colored aluminum "concave" out of the three-dimensional shape, simulating the dragon's scales.
"Wall top surface aluminum plate using anodic oxidation aluminum plate process, 'dragon scale' using oxidation process to form a bronze color, and then through the surface drawing process to form the surface texture." The person in charge said. "Dragon scales" after folding, behind the light transmission over, forming the feeling of scale highlights. At the bottom of the wall, it will also be partially embellished with mottled stone, simulating the elements of Nanjing's city wall.
Combination of open and concealed excavation, "hollowing out" the deepest subway station.Qingliangshan station underground a total of 7 floors, both near the city's west trunk road, but also to reserve with the planning of the subway line 13 of the interchange, the excavation depth of nearly 51 meters, equivalent to the height of 15-storey building, is currently the deepest subway station in Nanjing. Taking into account the project to minimize the construction site footprint, the excavation took half of the open cut and half of the concealed excavation method.
The project department dug shafts on the north and south sides of Guangzhou Road, and then dug on both sides to avoid open excavation from the road surface, interrupting the traffic, both to protect the traffic and construction, vehicle traffic and station construction. In the face of ultra-deep foundation pits and underground excavation projects, "Metro Guard" to strengthen the site supervision and frequency, guarding the quality and safety of the project.
▲ Cool Mountain Station Decoration Effect
Metro Line 7, which uses fully automated driving technology, will span Yuhuatai and Jianye districts when the entire line opens,Drumtower city district (various)The line will link the southwest and northeast of Nanjing with the Qixia District. Municipal Construction Committee Railway Station "Metro Guard" will continue to monitor the quality of construction, to promote the completion of the project before acceptance of the preparatory work, to ensure the smooth opening of the entire line operation.
