The Ninth Testing Department (Monitoring Institute) of Station Co., Ltd., a subsidiary of Guangdong Provincial Academy of Building Research, addressed pain points in traditional monitoring such as high operational environment risks, high manual monitoring intensity, and shallow data application,and built an integratedsolutionof "intelligent equipment + innovative methods + digital platform".Self-developed automated monitoring equipment such as flexible inclinometers, water level gauges, andimage grayscaledeformation measurement devices has achieved a leap from manual monitoring to unattended operation, with equipment costs significantly lower than imported products; newly created technologies such as a new method for measuring axial force of reinforced concrete struts and quantitative calculation of internal force of retaining piles break through traditional monitoring logic and provide more comprehensive and accurate monitoring data for judging foundation pit safety; the developed intelligent data mining platform establishes a multi-parameter fusion risk assessment system and, through lightweight neural network algorithms, completes "trend prediction" of monitoring data, creating a new model of proactive prevention and control for foundation pit safety.

Application of 5G intelligent monitoring vehicle in foundation pit engineering

     This technology has beenapplied in more than 2,000 projects in the Guangdong-Hong Kong-Macao Greater Bay Area，providing safety assurance for projects in Guangzhou, Shenzhen, Foshan, Zhuhai and other regions, promoting the implementation of 3 Guangdong provincial standards including the "Technical Specification for Automated Monitoring of Foundation Pit Engineering", and obtaining 15 authorized invention patents and 9 SCI/EI papers.According to the appraisal of scientific and technological achievements, the project technology has reached the international leading level.

     This achievement not only promotes the transformation of the monitoring industry from "labor-driven" to "data-driven", but also, through "all-weather intelligent early warning", builds a solid safety defense line for urban underground space development, accumulates key data assets for smart city construction, and demonstrates the power of wisdom in empowering infrastructure with science and technology.
