The dam of the head reservoir is the heart wall Dam, but due to the collapse of the dam, the separation of the upper part of the heart wall, in order to solve the problem of upper seepage prevention, the original addition to the impervious oblique wall. According to the safety proof analysis of the reservoir dam, in order to solve the leakage of weak surface and dam Foundation caused by multiple landslides of the dam, a bedrock curtain grouting, contact surface grouting, a backfill curtain of the casing well and a high spray impervious wall are adopted in vertical seepage control. In the upper inclined wall, the composite geomembrane blanket is used to prevent seepage, and the bottom is connected with the vertical cutoff wall to the $number. 0m elevation (above the check flood stage 0.97m). The concrete position and the engineering quantity see the design drawing.
