Smart lining System was developed to restore and improve water quality, hydraulic, and structural function of water large transmission pipes through the construction of the high quality lining in the study. Smart lining System consists of smart cleaning, smart spray-on lining, and smart CIPP2+. Smart cleaning is the pre-process of lining process, and could ensure SSPC SP-10 and surface roughness 50 μm(Rz) as the quality of surface preparation for the lining by removing effectively deposited slime, residual lining, tuberculation, graphitization of pipe wall with the high pressure water jet, mechanical scraper, and air spin-head blasting equipment step by step.
