Yuxia high -speed rail Yiyang to Changsha section

(Referred to as the long -term section of the Yuxiang high -speed rail)

Formally open operation

Yiyang South Station, Ningxiang West Station

Realize interconnection with Changzhutan Intercity Railway

Travel time from Yiyang to Changsha

Compress the original 70 minutes to the fastest 31 minutes

The Yuesha High -speed Railway Yijun Section line is 63 kilometers in length. It is connected to the Changzhutan Intercity Railway via Changsha West Station. It is designed at a standard speed of 350 kilometers per hour. 3 stations in Changsha West, of which Changsha West is a rebuilding station and does not handle the passenger business for the time being.

Create the window of national culture

There are three stations of Yiyang South Station, Ningxiang West Station and Changsha West Railway Station, all of which are undertaken by China Railway. Among them, Yiyang South Station and Ningxiang West Railway Station followed the long -term opening of the Yuxia high -speed rail.

Yiyang South Station

Yiyang South Station is located in Zhaizilun District, Heshan District, Yiyang City, Hunan Province. The construction area of ​​the station building is 35,962 square meters, and the stations are 2 6 lines. Based on the local mellow cultural heritage, Yiyang South Station adopts the shape of "large and small wings" to fully reflect the architectural creativity of "text and new flying". The spatial woven structure support and the shape design of the internal ceiling of the station lobby incorporate the "bamboo editor culture" element of Yiyang intangible cultural heritage.

The unique "size wings" shape makes the civil construction and steel structures interspersed with complex and mutual constraints. China Railway Construction Industry Group adopts the measures of "optimization nodes+partitions+detailed implementation" measures, and uses BIM technology to optimize component nodes to sort out the relationship between the structure between the structures to ensure the construction of the best process of the steel structure and the civil construction structure. Quality and efficiency.

Ningxiang West Station

Ningxiang West Station is located in Jinghua Pu Township, Ningxiang City, Hunan Province. The total construction area is 9990 square meters, and the station is 2 and 4 lines. The shape of Ningxiang West Station is inspired by the "Four Sheep Fang Zun" unearthed in Ningxiang's national treasure bronze ware. In the process of deepening the design process, the builders of China Railway Construction Group applied a large number of elements from local culture and oriental decorative art.

The indoor wall shape is abstract from the four sheep squares, and the wall of the wall is below the wall of the wall to echo the stable base of the four sheep squares. The main lamp of the ceiling is based on the square shape of the four sheep squares. During the construction process, the builders of China Railway workers fully overcome difficulties such as the epidemic, long rainy season, and high temperature weather. They formulated special construction plans for construction points and difficulties, and achieved the main structure of the main structure for 20 days in advance to ensure high -quality performance.

Changsha West Railway Station

Changsha West Railway Station is arranged by the total scale of 12 22 lines and 16 long -term and long -term 16 lines. Among them, there are 6 11 lines in Yuxia and 6 in the intercity field. The general speed field is reserved. The total area of ​​the Changsha West Station Hub is about 385,000 square meters. There are elevated station buildings. The station mode is up and down. The elevated waist enters the station.

Technology empowerment help production

The China Railway Shanghai Engineering Bureau undertakes 23.947 kilometers long. At the same time, the 590 -hole box beam and the entire line of 55412 CRTSIII -free rail panels.

The first double -spin beam across the entire line successfully completed the turntable

Since entering the market, the project department has not waited for or carefully organized, around the system construction, communication and coordination, construction organization, and scientific and technological innovation. During the construction of the weak surrounding rock tunnel, a series of technologies and security problems were overwhelmed.

During the construction of continuous beams and rotary beams of Yiyang Ringcheng Expressway Bridge, the project department set up a scientific and technological research team to carefully prepare scientific and feasible technical solutions, invite experts to participate in the evaluation of the plan, and refer to the actual construction situation on the spot to make reasonable adjustments; The construction staff carried out a strict construction technology interference, and simulated various interference problems in the construction, so as to detect and solve it in advance, and finally successfully completed the continuous beams of Lianghelong and the rotary beam.

Intelligent production line of Yiyang Board

On the basis of the previous CRTS III, Yiyang Board, on the basis of the automated production line of the French rail board, it took half a year to build an intelligent production line with the "PLC Central Control System" as its core, and achieved 9 intelligent stations and mechanical chemical locations. The practical and intelligent production has created a number of "first" of domestic rail board manufacturing technology for the first time to achieve mold cleaning automatic switching, de -mold spraying automatic switching, and automatic switching of single work levels, filling a number of domestic technology gaps. At present, the project has obtained 4 scientific research results, applying for 12 national patents, and promoting the production technology of China's high -speed rail -free rail board to achieve new breakthroughs.

Strictly grasp the quality of engineering construction

China Railway China Railway has undertaken the 3nd standard supervision tasks of the Yidian high -speed railway Yijiu section. Key projects in the pipe section include Zhixihe Extra Bridge, Yiyang Ringhuang Expressway Bridge, Shijiuchang Railway Bridge, Gongjiacun Tunnel (the longest tunnel on the entire line ), Yiyang South Station Room and so on.

In the process of supervision, in the face of the dual pressure of the project to overcome the tight construction period and the new crown epidemic, the project supervision department strengthened scientific overall planning, paid close attention to project management, strictly accepted and controlled, and completed the project supervision tasks high -quality to effectively ensure the safety and quality of the entire project.The participating units have been well received, and have won the "high -quality and brave double victory in the project" twice.Yiyang South Station Station Road Field

In the next step, after the operation of the Yugen to Yiyang section of the Yugen High -speed Railway, which was under construction, the Yuxiang high -speed railway Changde to Yiyang to Changsha section realizes the entire line.The travel of the people actively promotes the high -quality development of regional economic and society, and promotes the development of urban agglomerations in the middle reaches of the Yangtze River.
