On August 31st, the newly built Nanning to Liban high-speed railway was opened and put into operation, and the entire line of the Guinan high-speed railway was put into operation; On August 29th, the construction of station buildings along the entire Fuzhou Xiamen high-speed railway line was completed, laying a solid foundation for the opening and operation of the entire line within the year; On the same day, the first trial operation train of the Guangzhou Shantou high-speed railway was launched, entering the trial phase of train operation, and the countdown to the opening and operation of the entire line... Since the beginning of this year, China's high-speed railway construction has continued to maintain high speed and quality, laying the foundation for further improving operational capacity and improving network layout. The newly built high-speed railways, represented by the Fuxia high-speed railway and the Guinan high-speed railway, are steadily advancing on the intelligent road developed by the Beijing Zhangjiakou high-speed railway, and the construction of China's intelligent high-speed railway is on the fast track. In February 2018, the former China Railway Corporation fully launched the "Comprehensive Test of Intelligent Key Technologies for High Speed Railway" in the Liaoning section of the Beijing Shenyang high-speed railway, marking the first time China has conducted an intelligent high-speed railway test. In recent years, the latest technological achievements of intelligent railways have been integrated and applied in the construction of major high-speed rail projects. The digital management system of the track, the integrated construction system of the four electrical systems, the BIM+GIS high-speed rail intelligent network optimization system, and the integrated GIS system management platform for the construction and maintenance of the four electrical equipment have been comprehensively applied, effectively improving the level of intelligent construction. Having an intelligent brain to command. The entire Fuzhou Xiamen high-speed railway adopts BIM modeling technology, integrating new generation information technologies such as cloud computing, big data, and artificial intelligence with professional engineering technologies in different business areas of high-speed railways. Not only has it achieved visual dynamic management of the entire process of construction parameters, process monitoring, geological prediction, etc., but it also has information completeness, correlation, and consistency. With the protection of major powers and heavy weapons. In the stormy waters of the Meizhou Bay, China's most technologically advanced, versatile, and widely used kiloton high-speed railway box girder transport and erection machine, the Kunlun, has achieved a perfect "debut" at the construction site of the Fuzhou Xiamen High Speed Railway Meizhou Bay Cross Sea Bridge. The box girder weighing up to 1000 tons accurately landed between the bridge beams like building blocks. Hu Haibo, Chief Engineer of Fuxia Section 4 of China Railway 11th Bureau, introduced that the "Kunlun" is currently the most fully functional high-speed railway bridge lifting and erecting equipment in China, achieving an improvement in the technical level of high-speed railway construction in China. Supported by advanced technology. The contact network of the Guinan high-speed railway adopts the stress release process of the hanging string current carrying ring, which eliminates the bending stress of the hanging string current carrying ring, reduces the elastic tension of the current carrying ring, improves work efficiency, reduces maintenance costs, and can better ensure the safety of high-speed railway trains and passengers. With ecological concept guarantee. The Chengjiang Double Line Super Large Bridge of the Guinan High Speed Railway has a length of 2.56 kilometers, which happens to pass through the Chengjiang National Wetland Park area. In order to reduce the impact on the ecological environment and wildlife, Yunnan Guangxi Railway Company and China Railway Beijing Engineering Bureau Guinan High Speed Railway Project Department have repeatedly studied and innovatively developed a construction plan using a 56 meter long span segmental assembly beam, without the need for scaffolding and on-site concrete pouring and maintenance. The site under the bridge also does not need to undergo large-scale special treatment, which has minimal impact on the surrounding environment.? At 21:37 on September 4th, the CRH2A-2366 high-speed train slowly entered the inspection shed of Nanning Second High Speed Railway Station for maintenance work, which was used to encrypt Nanning and surrounding areas
