ABSTRACT

During the construction of civil engineering projects, the performance of slurry directly affects the quality and safety of underground diaphragm walls, bored piles, and similar structures. Traditional methods for slurry testing suffer from issues such as delayed response and data inconsistency, making them insufficient to meet the modern construction industry's demands for real-time monitoring and high precision. To address these challenges, this study aims to develop a quality control system based on online monitoring of slurry properties, thereby enhancing the controllability of construction processes and the stability of engineering quality. The research integrates sensor technology, data acquisition systems, and intelligent analysis algorithms to establish dynamic monitoring models for key slurry parameters, including viscosity, sand content, and pH value. These models enable closed-loop quality control through feedback from the construction site. Experimental results demonstrate that the monitoring system can effectively detect abnormal fluctuations in slurry performance with an accuracy rate exceeding 95%, significantly outperforming traditional manual testing methods. Further case applications show that this approach improves trenching (boring) quality across multiple engineering projects, reduces rework rates, and enhances both construction efficiency and safety. The innovation of this study lies in the integration of multi-parameter monitoring and intelligent early-warning mechanisms into slurry management, providing scientific support and technical foundations for quality control in civil engineering construction. This method holds strong potential for practical application and widespread adoption in the field.
