Core Viewpoint - The Nanzhu High-speed Railway segment from Yulin North to Cengxi East has entered the full-track laying phase, marking significant progress in the project aimed at improving transportation in eastern Guangxi [1][7]. Group 1: Project Overview - The Nanzhu High-speed Railway segment is constructed by Guangxi Transportation Investment Group and spans 84.895 kilometers with a design speed of 350 km/h [1]. - The project includes three stations: Yulin North, Rongxian South, and Cengxi East, with the latter two being newly constructed [1]. Group 2: Construction Details - The railway crosses the Gui East region, featuring 22 tunnels and 65 bridges, resulting in a bridge-tunnel ratio of 84.4% [3]. - The total track laying includes 167.9 kilometers of main line, 8.8 kilometers of station line, and 40 sets of turnouts, indicating a complex construction environment [3]. Group 3: Technology and Efficiency - The construction unit, China Railway No. 2 Engineering Group, has deployed advanced equipment such as the WZ500C traction vehicle and mobile flash butt welding machines, enhancing construction efficiency to a daily progress of 6 kilometers [6]. - A smart cloud safety scheduling management system has been implemented for digital, visual, and precise control of the track laying process, improving safety measures [6]. Group 4: Project Timeline and Impact - All groundwork, bridges, and tunnels for the Nanzhu High-speed Railway segment have been completed, with the main structure of the new stations at Rongxian South and Cengxi East reaching 80% completion [7]. - The project is expected to be completed and operational by February 2026, significantly improving transportation conditions in eastern Guangxi [6][7].

Core Viewpoint - The Nanzhu High-speed Railway segment from Yulin North to Cengxi East has entered the full-track laying phase, marking a significant milestone in the project [1][5]. Group 1: Project Overview - The Nanzhu High-speed Railway Yulin North to Cengxi East segment is constructed by Guangxi Transportation Investment Group and overseen by the Nanning Bureau of China Railway, with a total length of 84.895 kilometers and a design speed of 350 kilometers per hour [2]. - The project includes three stations: Yulin North, Rongxian South, and Cengxi East, with the latter two being newly constructed [2]. - The railway passes through the Gui East region and features 22 tunnels and 65 bridges, resulting in a bridge-tunnel ratio of 84.4% [2]. Group 2: Strategic Importance - The Yulin North to Cengxi East segment is an extension of the Nanzhu High-speed Railway and is crucial for Guangxi's integration into the Guangdong-Hong Kong-Macao Greater Bay Area [4]. - Once completed, the railway will enhance the regional transportation network and play a vital role in establishing Guangxi as an important strategic hub within the Greater Bay Area, promoting the economic interaction between the Beibu Gulf Economic Zone and the Greater Bay Area [4].

Core Viewpoint - The successful completion of the Tianxing No. 1 tunnel marks significant progress in the construction of the Nanzhu High-Speed Railway segment from Yulin North to Cengxi East, with all 22 tunnels in this section now fully connected, paving the way for subsequent track laying and construction work [1] Group 1: Project Details - The Tianxing No. 1 tunnel, located in Cengxi City, has a total length of 4,574.71 meters and a maximum burial depth of approximately 165 meters, facing complex geological conditions including rock deformation and structural collapse risks [1] - The construction team utilized advanced equipment such as a new generation of self-propelled hydraulic arch bridge, intelligent digital pouring lining vehicles, and ventilation systems to ensure quality and progress during the tunnel excavation [1] Group 2: Project Timeline and Impact - The main line of the Nanzhu High-Speed Railway from Yulin North to Cengxi East spans 84.759 kilometers and is currently in a comprehensive construction phase, with the "four electrical" systems and station building projects progressing in an orderly manner [1] - The ballastless track construction has commenced, with an expected completion and opening for traffic next year, which will significantly improve transportation conditions in the eastern Guangxi region and promote economic and social development along the route [1]
