- Abstract
In order to effectively solve the seriousdam leakage problem of the thin mountain on the right hank of Qihe Panshitou Reservoir in Henan Province, a grouting curtain method was designed to prevent seepage under the normal operation. In order to verify the rationality and feasibility of the design parameters of the grouting curtain under high water head moving state and further optimize the construction technology, productive test was carried out before grouting curtain construction. Based on the basic design parameters of the anti-seepage curtain of Jiguan mountain, a representative test area was selected by the production test. Different grouting pressures and water-ash ratios were used for the grouting test. The experimental results verify that the application of initial design parameters of grouting curtain can meet the design expectations ; grouting the upstream curtain first is better; the sealing grouting method of orifice is suitable for the I and II sequence holes and the sectional grouting method is suitable for the III sequence holes.
