南工大科研团队破解软土路基建造难题，为软土固化找到了高性能“环保胶水”

Core Viewpoint - The project led by Professor Wu Zhijian from Nanjing University of Technology addresses the challenges of constructing roads and railways in soft soil areas, providing low-carbon and intelligent solutions that transform industrial waste into sustainable roadbed materials [1][9]. Group 1: Innovation in Materials - The project utilizes industrial solid waste such as smelting slag and fly ash as raw materials, creating a new green gel material that reduces carbon emissions by 92% compared to traditional cement production, while also lowering costs by over 25% [2][3]. - The new technology allows for the direct transformation of soft soil into qualified roadbed material, significantly reducing transportation costs and environmental issues associated with traditional methods [2]. Group 2: Advanced Equipment and Techniques - The team developed high-efficiency equipment capable of processing 400 cubic meters per hour, which is more than three times the capacity of traditional equipment, leading to a cost reduction of 20%-40% for soft soil solidification [3]. - Innovations include lightweight solidified soil that reduces additional stress by 50% while increasing vertical bearing capacity by 38.3%, thus minimizing settlement issues [3]. Group 3: Intelligent Monitoring Systems - The project features a smart monitoring system that provides real-time assessments of roadbed integrity, significantly improving detection accuracy and efficiency compared to traditional methods [6]. - The system can issue alerts within 30 seconds of detecting anomalies, enhancing safety during construction and allowing for real-time carbon reduction assessments [6]. Group 4: Economic and Environmental Impact - The technology has been applied in 26 major national projects, generating nearly 6.5 billion yuan in new output value and over 330 million yuan in profit [7]. - The project has successfully converted over 3.6 million cubic meters of construction waste into usable materials, avoiding pollution from landfill and achieving cost savings of over 70% in road construction [7]. Group 5: Future Prospects - The technology is recognized as internationally leading and is expected to be promoted in other soft soil regions, contributing to the dual carbon goals in transportation infrastructure [9].
