Scope of composite geomembrane

The Zhoutou Reservoir Dam was originally a core wall dam, but due to its collapse, the upper part of the core wall became detached. In order to solve the upper anti-seepage problem, an anti-seepage inclined wall was originally added. According to the safety analysis of the Zhoutou Reservoir Dam in this study, in order to solve the leakage weak surface and dam foundation leakage caused by multiple landslides of the dam, anti-seepage structures such as bedrock curtain grouting, contact surface grouting, flushing and grabbing well backfilling curtain, and high-pressure spray anti-seepage plate wall have been adopted in vertical anti-seepage. The upper inclined wall is covered with composite geomembrane for anti-seepage, which is connected to the vertical anti-seepage wall at the bottom and reaches an elevation of 358.0m (0.97m higher than the check flood level)
