Especially, grouting technology in water conservancy and hydropower projects has become a technical measure often used in foundation construction in water conservancy and hydropower projects. For some special strata, such as extra-large leakage channels, large grout-sucking strata, karst areas, water plugging due to water inrush, etc., the grouting methods and techniques used are different. At present, in the development process of water conservancy and hydropower projects, most of them need to use relevant grouting methods. This paper will explore the grouting method of special strata in foundation grouting in water conservancy and hydropower projects.展开更多

Based on the real-time control technology, the optimization method and the set theory, a mathematical model of the system is established. The real-time collection and transmission technology of the grouting data provides a data foundation for the system. The real-time grouting monitoring and dynamic alarming method helps the system control the grouting quality during the grouting process, thus, the abnormalities of grouting, such as jacking and hydraulic uplift, can be effectively controlled. In addition, the 3D grouting visualization analysis technology is proposed to establish the grouting information model(GIM). The GIM provides a platform to visualize and analyze the grouting process and results. The system has been applied to a hydraulic project of China as a case study, and the application results indicate that the real-time grouting monitoring and 3D visualization analysis for the grouting process can help engineers control the grouting quality more efficiently.展开更多
