Seepage often occurs in the construction of water conservancy projects.The foundation anti-seepage treatment can effectively avoid this situation,prevent the seepage speed too fast,and make the water conservancy project safer.Curtain grouting is the most basic and effective way to prevent seepage.Through taking a reservoir water conservancy project as an example,the study analyzes the key technical points of curtain grouting construction,and evaluates the quality and effect of curtain grouting.The test results show that ω≤5 Lu meets the water absorption requirements,and the number of sections ω＜1 Lu,ω=3～5 Lu and ω=1～3 Lu account for 13％,32％and 54％,respectively,indicating that this technology can be widely promoted in water conservancy projects to improve construction quality.
