建设者假日坚守岗位 重大工程建设“进度条”不断刷新

Core Viewpoint - The construction of the Harbin-Yichun High-Speed Railway (Ha-I Railway) is progressing rapidly, with significant advancements made during the recent holiday period, highlighting the commitment to infrastructure development in China. Group 1: Project Overview - The Ha-I Railway is an extension of China's high-speed rail network, specifically the Jingha to Jinggang'ao corridor, and is notable for being the highest latitude railway that traverses permafrost regions [1] - The railway spans a total length of 318 kilometers, with a design speed of 250 kilometers per hour, significantly reducing travel time from Harbin to Yichun from approximately 7 hours to about 2 hours upon completion [16] Group 2: Construction Progress - During the National Day holiday, it is expected that 40 kilometers of track will be laid, achieving 35% of the total track-laying task [15] - The track-laying process involves advanced machinery, with a single track-laying machine capable of laying at least 2.5 kilometers of steel rail in one day [5] Group 3: Technical Innovations - The railway utilizes seamless rail technology, which enhances track smoothness, safety, and passenger comfort by eliminating the noise associated with traditional rail joints [9] - The construction process includes the use of specialized machinery for ballast placement and track alignment, ensuring optimal track conditions [13] Group 4: Regional Impact - Currently, 8 out of 13 prefecture-level cities in Heilongjiang Province have operational high-speed rail services, with a total operational mileage exceeding 1,400 kilometers, indicating a shift towards more accessible rail transport [18]
