Abstract
This paper investigates the integrated application of the GIN grouting method and intelligent grouting system in rock mass grouting, using the Lesotho Polihali Dam project as a case study. To address the challenges of difficult control, low efficiency, and significant quality fluctuations associated with conventional grouting methods under complex geological conditions, the GIN grouting method, which employs grouting energy as its core control parameter, is adopted. An intelligent grouting system equipped with real-time data acquisition, parameter adjustment, and intelligent grout stop capabilities is introduced to achieve full-process automation of the grouting operation. Through comparative analysis with traditional grouting techniques, the study demonstrates that this integrated technology offers significant advantages in grout diffusion control, construction efficiency enhancement, and grouting quality assurance, thereby validating its feasibility and superiority for projects under similar complex geological conditions.

Abstract
This paper investigates the integrated application of the GIN grouting method and intelligent grouting system in rock mass grouting, drawing upon the case study of the Polihali Dam project in Lesotho. Conventional grouting methods face significant challenges under complex geological conditions, including difficult control, low efficiency, and substantial quality fluctuations. To address these issues, this study employs the GIN (Grouting Intensity Number) grouting method, which uses grouting energy as its core control parameter, and introduces an intelligent grouting system equipped with real-time data acquisition, parameter adjustment, and intelligent grout stop capabilities to achieve full-process automation of the grouting operation. Through comparative analysis with traditional grouting techniques, the research demonstrates that this integrated technology offers significant advantages in grout diffusion control, construction efficiency improvement, and grouting quality assurance, thereby validating its feasibility and superiority for projects with similar complex geological conditions.
