The reservoir dam was originally a core wall dam, but due to the collapse of the dam, the upper part of the core wall was disconnected. To solve the problem of upper anti-seepage, an anti-seepage inclined wall was originally added. According to the safety assessment and analysis of the Zhoutou Reservoir dam, in order to solve the weak leakage surface and dam foundation leakage caused by multiple landslides of the dam, vertical anti-seepage measures such as bedrock curtain grouting, contact surface grouting, flushing and grabbing sleeve well backfilling curtain, and high-pressure spray anti-seepage plate wall were adopted. The upper inclined wall is covered with composite geomembrane for anti-seepage, and is connected to the vertical anti-seepage wall at the bottom, reaching an elevation of 358.0m (0.97m above the check flood level)
major function
1. Integrating anti-seepage and drainage functions, while also possessing functions such as isolation and reinforcement.
2. High composite strength, high peel strength, and high puncture resistance.
3. Strong drainage capacity, high friction coefficient, and low linear expansion coefficient.
4. Good aging resistance, wide adaptability to environmental temperature range, and stable quality.
