Construction Technology of Surface Advanced Consolidation Grouting in Karst and Fissure Development Area
Consolidation grouting is a common construction method in hydraulic engineering construction.Consolidation grouting can effectively improve the development of rock joints and fractures or rock fragmentation,enhance the physical and mechanical properties,as well as the overall integrity and homogeneity of rocks.At the same time,it increases the elastic modulus and compressive strength of the rock mass,reduces deformation and uneven settlement of the rock mass,and improves construction safety.Taking the surface advanced consolidation grouting of a karst area in a water conservancy project in Shenzhen as the research object,this paper summarizes the problems and treatment measures encountered in the construction process of consolidation grouting in karst and fissure development areas,and studies the construction technology and measures of consolidation grouting in karst development areas.
