Weilai high speed railway has come in the future

On December 7, at the construction site of Laixi super major bridge of Weilai high speed railway, with a track laying locomotive steadily pushing two 500m long rails into place, the laying of Weilai high speed rail officially started, which also marks that the project officially enters the track laying construction stage.

as an important part of the layout of the "four horizontal, six vertical and three ring" high-speed railway network of Shandong Province. After the opening of Weilai high-speed railway, it will facilitate the travel of the citizens in Pingdu, Yantai, Weihai and other places in Qingdao, and also realize the "two-hour life circle" of Jinan and Yantai. At that time, it took only 50 minutes for Jinan to reach Pingdu. The reporter learned that on the 7th, the laying of Weilai high-speed rail began officially, and will be completed and opened to traffic next year, to meet you. Reporter Bai Xin D sun

Weilai high speed railway starts to lay long track. Next May,

is completed. On December 7, next year, at the construction site of Laixi super bridge of Weilai high speed railway, with a track laying locomotive steadily pushing two 500m long rails into place, Weilai high speed railway starts to lay long track, which also marks that the project officially enters the track laying construction stage. A 6031 a 6031 reporter learned on the spot that Weilai high-speed railway laid 258.371 kilometers in total, with a track laying base in Laixi. The project leader told reporters that on October 14 this year, the first 500 meter long rail train of Weilai high speed railway arrived at Laixi track laying base. By the end of November, the track laying base has 112.5 kilometers of track, and the planned daily long track laying is more than 6 kilometers. It is expected that the whole track laying will be completed by the end of May next year.

"the 500m long track laying process has special construction environment, high quality and precision requirements. After the long track is laid into the trough, a series of works such as unit rail joint welding, stress release and seamless track locking are also required. After each process is completed, the track can be put into operation after fine adjustment, acceptance and joint commissioning and test." According to the person in charge of Weilai Project Department of China Railway 14th Bureau, the track laying unit, in order to ensure the construction safety, the project adopts the independently developed remote electronic protection and early warning system, which can timely, accurately and effectively realize the remote alarm function. When the locomotive runs within 2000 meters from the construction site, the alarm light will flash and continuously give a voice alarm, which will prompt the locomotive running speed and distance, and remind it Operators timely avoid, and the construction safety factor of the project line is greatly improved. A 6031 a 6031 will be opened to traffic next year. The "two hour living circle" of Jiyan will come to a 6031 a 6031. According to the plan, Weilai high-speed railway will be led from Weifang North Station of Jiqing high-speed railway, passing through Changyi, Pingdu and Laixi to the East, and then to Laixi North Station of Qingrong intercity. The main line is 125.757km long, which is a double track high-speed railway with a design speed of 350km / h. Weifang north, Changyi South and Pingdu are set up Four stations in the north and northwest of Laixi. The construction of the whole line will be started on January 1, 2018, and it is planned to meet the traffic conditions by the end of 2020.

"at present, the subgrade, bridge foundation, box girder erection, tunnel and other works under the track in the project area are basically completed, and the construction of ballastless track, high-speed turnout, station building, four electric engineering and other works is started in an all-round way, among which, ballastless track has completed 128 single track kilometers, 59% completed." According to the project leader, the total investment of Weilai high speed railway project is 16.133 billion yuan, 5.04 billion yuan in 2019, 91.6% of the annual plan of 5.5 billion yuan. Up to now, Weilai high speed railway has invested 10 billion yuan, 62% of the total investment. The reporter of

learned that Weilai high speed railway is an important part of the "four horizontal, six vertical and three ring" high speed railway network layout of Shandong Province, which takes into account the function of Pingdu Qingdao (suburban) railway and mainly undertakes the passenger communication between Yantai, Weihai, Weifang and the West. After the completion of the project, it will become a convenient channel from the eastern part of Jiaodong Peninsula to the mainland, which is of great significance to strengthen regional ties, promote the development of small and medium-sized cities along the line, promote the formation of regional urban agglomerations, and improve the rational division of labor and structural transformation and upgrading of urban agglomerations.

at the same time, after the opening of Weilai high-speed railway, the trains in Yanwei area do not need to detour Jiaozhou north station. Through Weilai high-speed railway, they can reach Weifang, Zibo, Jinan and all parts of the country in a straight line, realizing the "two-hour life circle" between Jinan and Yantai. It only takes 50 minutes for Jinan to reach Pingdu. After the completion of Weilai high speed railway, it will also relieve the pressure of "the schedule is full" of Jiaoji passenger dedicated line, provide objective conditions for Qingrong intercity line to open more cross line bullet trains, put wings in the operation of Qingrong intercity line, and activate the operation of the whole Qingrong intercity railway. At that time, Qingdao Pingdu, Yantai, Weihai and other places will be more convenient for citizens to travel.
