Abstract: Water and sand leakage accidents often occur in shield tunnels, and grouting is the common emergency treatment method. Because the underground environment is often dynamic water conditions, the grouting materials have high requirements, which need to comprehensively consider the properties of grouting materials, such as setting time, dynamic water retention rate and water plugging rate. Through the laboratory tests on six kinds of grouting materials: polymer materials, marithan, double-grouting, reaction of two-component water polyurethane, paste slurry mixture with sodium silicate, and polymer materials and double-liquid mixture, the plugging effect and mechanism of grouting materials are analyzed, and the quantitative evaluation parameter, water plugging ratio, is put forward.
