Innovation of Waterproofing Technology for the Secondary Lining of Diversion Tunnel under Water-rich Environment
The waterproofing construction technology in the construction process of water-rich tunnel largely determines the effect of the tunnel construction.If the secondary lining concrete falls off,cracks occur during the construction,or the flatness of the water stop belt is very poor,all these will lead to water leakage in the tunnel,which will bring adverse effects on the project operation.Based on the tunnel construction of Songhua River water diversion project in some city in central Jilin Province,this paper analyzes the role of longitudinal pipe retreat grouting process with mold for secondary lining arch,self-adhesive reverse adhering waterproofing board,new water stop clamp and other new technology in solving the common engineering problems like tunnel second lining crack,water seepage,water leakage,cavitation,poor straightness of water stop belt and so on.
