📋 Tender Overview
Open for operation! Recently, Taiyuan Rail Transit Line 1 was officially opened for initial operation, forming a "power" rail transit network architecture with the existing Line 2, and Taiyuan Metro has thus entered the "transfer era".
Successfully completed! On February 25, the Ankang Tunnel, a key and difficult project of the Xi'an-Ankang High-speed Railway in Shaanxi Province, was successfully completed. This is the fourteenth tunnel completed on the entire Xikang High-speed Railway. So far, various projects such as the Xikang High-speed Railway tunnel, bridge, roadbed, station building, and track have been launched on a large scale, and the construction progress is accelerating.
Major projects are large in scale and are of great significance to ensuring and promoting economic development. Entering 2025, a number of major engineering projects in various places are under construction non-stop, and the "progress bar" is constantly refreshed, injecting continuous impetus into economic and social development.
Vehicles shuttled back and forth, and the sound of machines rumbled. 62 meters underground, in the cab of the "Yongzhou" shield machine with a diameter of 14.57 meters, Yu Juncheng, the tunnel supervisor of the Yongzhou Railway Project of China Railway 14th Bureau, stared at the screen in front of him, adjusted the buttons in his hands, and accurately controlled the excavation posture of the shield machine.
The 16.18-kilometer-long Jintang undersea tunnel of the Ningbo-Zhoushan Railway is the world's longest undersea high-speed railway tunnel. The 11.21-kilometer shield section has to undergo 28 changes in soft and hard strata, and the "Yongzhou" shield machine is responsible for the 4,940-meter construction task on the Ningbo side, which needs to challenge 24 changes.
"The shield machine has excavated 1,500 meters in total and is expected to enter the sea area in May." Yu Juncheng said that the project team will use intelligent means to conduct random inspections and replacements of the cutters to ensure that the shield machine is in the best condition and the project is smoothly advanced. After the completion and operation of the Ningbo-Zhoushan Railway Project, the history of Zhoushan Islands without railways will end, and Zhoushan, Zhejiang, the only prefecture-level city in the Yangtze River Delta without high-speed railways, will be connected to the national railway network.
From the full-speed advancement of the construction of the Chongqing section of the Chengdu-Chongqing Central Line, the acceleration of the third-phase expansion of Guangzhou Baiyun Airport, to the successful capping of the upstream side of the right pier of the upper lock of the Pinglu Canal Madao Hub... Since the beginning of this year, the construction of transportation projects in various places has continued to advance, and the national comprehensive three-dimensional transportation network has been accelerated.
With the completion of welding of the first section of the Sichuan-Eastern Gas Pipeline II in Anhui Province, the province with the longest pipeline, the construction of the eastern section of the Sichuan-Eastern Gas Pipeline II has been accelerated in the three provinces of Hubei, Zhejiang and Anhui.
Zhao Shi, deputy general manager of the National Pipeline Network Group Construction Project Management Company, said that as of now, 220 kilometers of welding has been completed in the western section of the project from Weiyuan, Sichuan to Tongliang, Chongqing, with an overall progress of over 70%. It is expected that the Sichuan-East Gas Transmission Line 2 project will be fully connected in 2027. By then, the Sichuan-East Gas Transmission Line 2 will be operated in conjunction with the existing Sichuan-East Gas Transmission Pipeline, which can increase the annual gas transmission volume by about 14 billion cubic meters, ensure the smooth flow of natural gas transmission channels in the Sichuan Basin, and help flexibly allocate resources in the region.
Pipelines are continuously extending and expanding energy channels. Since the 14th Five-Year Plan, the National Pipeline Network Group has accelerated the construction of oil and gas pipeline network infrastructure. It is expected that more than 2,000 kilometers of pipelines will be built by 2025, with an additional primary pipeline capacity of 25 billion cubic meters.
At the China Mobile data center project site in the "East Data West Computing" Industrial Park in Qingyang City, Gansu Province, workers are busy installing data lines.
"The five-story data center we are building this year is being accelerated, and we are striving to put it into operation in the third quarter. The new steel structure data center is also in the early stages of preparation. After the construction of the two data centers is completed, it is expected to add 50,000P (1P is approximately equal to 100 trillion computing times per second) of computing power capacity." said Jing Lirong, manager of the East-West Computing Center of Qingyang Branch of China Mobile Gansu Company.
New infrastructure, new space. At present, the Qingyang data center cluster has built and put into operation 31,000 standard racks, with a computing power scale exceeding 50,000P. The number of racks, computing power scale, and enterprise ecology have all been greatly improved, and can provide customized, one-stop computing power services for office software AI capabilities, smart driving business, education, finance and other fields in the eastern region.
