Weilai high speed railway officially enters the track laying construction stage and is expected to be completed in May next year

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. A 6031 a 6031 is the first large-scale public bidding procurement of long track for infrastructure construction in China, with a total length of 258.371 track laying kilometers. A track laying base is set up in Laixi. At present, in the period of railway rail supply reform, China Railway Group is no longer responsible for the rail procurement and transportation of local investment railways. Weilai high speed railway company actively responded to this complex situation, faced many difficulties in customer service, completed the first large-scale public bidding and procurement task of long rail infrastructure in the whole road, sent people to the front line for many times, actively connected with steel plants and rail welding bases, implemented the rail production plan and long rail welding plan, dispatched and solved the problems encountered in the process, and coordinated and rationalized the supply chain. On October 14, 2019, the first 500m long rail train of Weilai high speed railway arrived at Laixi track laying base, which was efficient and smooth. By the end of November, the track laying base had been 112.5km. A number of technical measures have been taken to ensure the construction safety. The construction environment for laying 500 meter long track is special, with high quality and accuracy requirements. After the long track is laid in the trough, a series of works such as unit rail joint welding, stress releasing and seamless track locking must be carried out. After the completion of each work sequence, the track can be put into operation after fine adjustment, acceptance, joint commissioning and joint test That's ok. In order to ensure the construction safety, Weilai high speed railway company and Weilai Project Department of China Railway 14th Bureau Co., Ltd. have jointly developed a remote electronic protection 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 continue to give voice alarm to remind the locomotive running speed and distance The construction safety factor of the project line is greatly improved. In addition, the Intelligent Cloud security dispatching management system is used in the track laying construction, which is a comprehensive security dispatching management platform integrating vehicle personnel security management, video monitoring, remote dispatching, real-time communication, data collection and sorting, and greatly improves the efficiency of track laying construction. By the end of May next year, the track laying of the whole line of

will be completed. By the end of next year, the track laying unit of

will be ready for operation. This time, a high-speed rail laying unit will be used to lay the track from Laixi to Weifang. The daily laying length of the track is more than 6km. It is expected that the track laying of the whole line will be completed by the end of May next year. The

Weidu Laixi high speed railway is led from Weifang North Station of Jinan Qingdao high speed railway, passing through Changyi, Pingdu and Laixi in the East, and leading into Laixi North Station of Qingdao Rongcheng intercity. The main line is 125.757km long, which is a double track high-speed railway with a design speed of 350km / H. four stations are set up in Weifang north, Changyi south, Pingdu north and Laixi northwest. 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 are basically completed, and the construction of ballastless track, high-speed turnout, station building, four electrical engineering and other works is started in an all-round way. Among them, the ballastless track has completed 128 single track kilometers, 59%. The total investment of the

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

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 railway function from Pingdu to Qingdao (suburb), and mainly undertakes the passenger traffic 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.
