Recently, the Chongqing-Qianjiang section of the Chongqing-Xiamen High-speed 188bet casino was officially launched. After the line is opened, it takes only 3 hours and 53 minutes to reach Chongqing from East to Changsha. Chongqing-Changsha enters the 4-hour high-speed rail circle.
Recently, the Chongqing-Qianjiang section of the Chongqing-Xiamen High-speed 188bet casino was officially launched. After the line is opened, it only takes 1 hour to get from Chongqing East Station to Qianjiang Station, and it takes only 3 hours and 53 minutes to get there. Chongqing-Changsha enters the 4-hour high-speed rail circle.
The reporter learned that the Chongqing-Xiaxia High-speed 188bet casino section starts from Chongqing East Station, passes through Nan'an District, Banan District, Nanchuan District, Wulong District, Pengshui Miao and Tujia Autonomous County, and Qianjiang District, and connects to Qianjiang Station of Qianjiang to Zhangjiajie to Changde High-speed 188bet casino. The main line is 242 kilometers long and has a designed speed of 350 kilometers per hour.
The opening of the Chongqing East to Qianjiang section makes it possible to reach Chongqing from Qianjiang in one hour. The once bumpy 6-hour mountain road was completely ended by the high-speed rail. The travel time from Chongqing to Changsha has also been greatly reduced, with the fastest reaching 3 hours and 53 minutes. Previously, from Changsha to Chongqing, it was necessary to detour Guiyang, and the fastest high-speed train between the two places took 5 hours and 11 minutes.
"The geological structure in Chongqing is complex, and compared with the past, it puts forward higher requirements for construction." Kuang Canrong, technical director of the front 6th standard project of the Chongqing-Qianjiang Railway Station of 188bet casino 18th Bureau, said that the Chongqing East to Qianjiang section line crosses the karst landform in the Wuling Mountains, which has also accumulated rich experience for subsequent construction of such tunnels and bridges.
Taking the Nanzhushan Tunnel with a total length of 10.8 kilometers as an example, the tunnel passes through the karst geological fault zone of the Jinfo Mountains, with cave groups and landslides, and construction difficulty and safety risks are rare in China.
"We used long tunnels and short tunnels to organize construction at the same time, used advanced detection technology, predicted in advance, adjusted in time according to geological changes, optimized the technical plan, and successfully crossed 6 geological fault zones and cave groups to ensure the safe passage of the tunnel in advance. More importantly, the Nanzhushan Tunnel also provides important data for the scientific research and construction of special long tunnels under adverse geological conditions in my country." Kuang Canrong told reporters.
In addition to innovating in construction methods and technology, the construction of Chongqing East to Qianjiang section also made great breakthroughs in management efficiency.
Xu Shipeng, deputy chief engineer of 188bet casino Electrochemical Bureau, told reporters that the standardized and fusionable BIM three-dimensional model constructed by the project team can transform floor drawings into intuitive three-dimensional solutions. With the help of this model, the operator can view the 720-degree panoramic diagram by scanning the QR code through his mobile phone, making the design plan clear at a glance, realizing the transformation from "construction according to the drawing" to "three-dimensional construction", shortening the plan decision-making cycle by 35% and reducing material loss by 20%.
"The project team also independently developed the 'four-electric' interface management platform and opened data channels for mobile phone WeChat and computer terminals. On-site interface inspectors can upload the location and number of problems instantly, the unit in front of the station can receive rectification tasks simultaneously, and the supervision unit tracks and supervises the number of charges throughout the process. This digital closed-loop management model increases the efficiency of rectification and cancellation of interface problems by 60%. "Xu Shipeng added.
It should be noted that with the opening of the Chongqing East to Qianjiang section of the Chongqing-Xiamen High-speed 188bet casino, Chongqing East Station, the largest high-speed 188bet casino hub in the western region, which has been built for more than three years, has also been officially put into operation today.
Chongqing East Station adopts a "four-side entry" layout, with a total of 4 floors and a building area of 120,000 square meters. It realizes the "four network integration" of trunk railways, intercity railways, urban (suburban) railways and urban rail transit. Passengers can transfer between different rail transit networks within 5 minutes.
"The world's first super high and super large curved tree-shaped column design is adopted at the main entrance of Chongqing East Station. Each 41-meter-high "steel yellow tree" is spliced by nearly 1,200 stainless steel plates; the roof streamers are inspired by the water-grained form at the intersection of the Yangtze River and the Jialing River. The colorful glass and roof streamers complement each other, combining artistic beauty and practical functions, meaning 'landscapes and Bayu'." Jiang Qianwen, the architectural design director of Chongqing East Station of 188bet casino Second Hospital, explained.
Walking into the waiting hall of Chongqing East Station, five island air conditioners with a height of 4 meters stand among them. This is the first time that camellia integrated island air conditioner has been used in the southwest region. It is not only beautiful and generous, but also has a more uniform and comfortable air supply effect.
Chongqing East Station is a pilot project for the construction of a strong transportation country to integrate stations and cities and an important fulcrum for the new western land-sea channel. In the early stages of opening, Chongqing East Station was connected to the Chongqing-Xiaxi High-speed 188bet casino, connecting southeastern Chongqing, Hunan, Jiangxi, Fujian and other places; in the future, it will also be connected to several high-speed railways and rail transits such as Chongqing Wan and Yugui, becoming a super hub integrating high-speed railways, rails, buses and commerce.
The reporter learned that the Chongqing section of the Chongqing-Xiaxi High-speed 188bet casino connects more than 30 ethnic minority areas such as Miao and Tujia along the route, with rich cultural and tourism resources and beautiful natural scenery. After the Chongqing-Xiamen High-speed 188bet casino is opened to traffic, the fastest time for train travel from Chongqing's main urban area to Qianjiang District will be shortened from the current 4 hours to within 1 hour, which is of great significance to improving the layout of the high-speed 188bet casino network, accelerating the formation of the main high-speed 188bet casino channel from Chongqing to Xiamen, and driving the economic and social development of the areas along the route.
