南宁地铁6号线，有新进展！

Core Viewpoint - The successful completion of the right-line shield tunnel section from Tongle Station to Dingqiupo Station marks the first dual-line completion of the Nanning Metro Line 6, laying a solid foundation for subsequent construction [1] Group 1: Project Details - The dual-line tunnel of the Tongding section is approximately 1,883 meters long, traversing through 280 meters of full-section gravel layer and 230 meters of full-section fine sand layer [1] - The construction faces challenges such as high groundwater levels and strong permeability, which can lead to risks like surging, quicksand, surface subsidence, and even collapse during excavation [1] Group 2: Safety Measures - Nanning Rail Transit Construction Group has implemented three major measures to enhance safety: upgrading shield machine equipment, establishing an intelligent monitoring platform, and introducing "four new" technologies [1] - The shield machine has been equipped with a "four small pieces" system to strengthen risk management during excavation and improve the working environment for workers [1] - A digital platform for intelligent construction has been created to enable real-time data upload of key excavation data, allowing for timely risk management [1] Group 3: Technological Innovations - The project has adopted a "new steel-concrete composite segment" technology for the first time, addressing various challenges associated with traditional all-steel segments, providing a reference for future projects [1] - The combination of manual and intelligent control has ensured the safe and smooth progress of the construction, resulting in high-quality assembly of the formed segments [1] Group 4: Future Plans - Nanning Rail Transit Construction Group will continue to adhere to the "four modernizations and one greening" management philosophy, focusing on quality engineering and advancing the subsequent construction of Line 6 in an orderly manner [1]
