In order to explore the construction technology of dam curtain grouting,and help to improve the quality of dam reinforcement,the study takes a reservoir as an example;analyzes the seepage flow of reservoir dam;designs the process parameters,such as grouting materials,grouting machinery and curtain parameters;and optimizes the construction technology of curtain grouting.After curtain grouting reinforcement,the study conducts the test of checking pore pressure water in the grouting area to track the permeability behind the dam.The results show that the permeability is below 5 Lu,which meets the anti-seepage standard.It can be popularized and applied.
