Application of Curtain Grouting Technology in Tunnel Construction through Water-rich Fault Fracture Zone
Taking a tunnel project as the research object,this paper discusses the application of full-face advanced curtain grouting technology in the construction of high-risk and water-rich fracture zone.Through effective tunnel water inrush control,the construction safety of the tunnel is ensured.This paper summarizes the full-section advanced curtain grouting technology and related parameters in the construction of tunnel crossing high-risk fracture zone,and puts forward the technical points from the aspects of grouting wall construction,grouting reinforcement of grouting rock plate and compression test of grouting wall,which can provide reference for related research.
