我市15个项目入选省级智能建造试点项目

Core Insights - A new batch of intelligent construction pilot projects in Jiangsu Province has been announced, with 15 projects from Nanjing selected, covering various types such as hospitals, residential developments, transportation hubs, and rail transit [1] Group 1: Intelligent Construction Projects - Nanjing North Station is highlighted as the largest railway hub station in the northern Jiangsu section of the national "eight vertical and eight horizontal" high-speed rail network, focusing on full lifecycle digital management to set a benchmark for intelligent construction in railway hubs [1] - The project utilizes cutting-edge technologies such as IoT, big data, and artificial intelligence to establish a panoramic intelligent construction management platform, featuring eight core modules and over 30 scenario-based applications for comprehensive smart control throughout the construction process [1] Group 2: Smart Construction Techniques - The intelligent construction phase implements full-process digital control, including a Beidou automated monitoring system for deep foundation stress and displacement data collection, real-time monitoring of temperature differences in 143,000 cubic meters of large-volume concrete, and a smart electricity system that monitors line status 24/7 [1] - Various construction robots have been deployed, significantly enhancing the precision of construction processes, including leveling, polishing, and sealing operations [1] Group 3: Metro Line 4 Phase II - The second phase of Metro Line 4 is noted as Nanjing's fourth cross-river metro line, with the core control project being the shield tunnel section between Binjiang Station and Jiangxinzhou, which is the deepest cross-river metro tunnel in the Yangtze River Delta region at 68.58 meters below the water surface [2] Group 4: Challenges and Innovations - The tunnel section faces significant challenges due to complex geological conditions, including soft soil, gravel, and mudstone, with high water pressure and risks of leakage, requiring advanced technical solutions [2] - The project employs a multi-level excavation control system based on a smart shield management system, achieving remote control capabilities for shield machines, and has developed a fourth-generation tool-changing robot that reduces tool change time to one-third of traditional methods [2]
