Most small reservoirs in China were built during 1950s to 1970s, with low engineering standards and poor quality. Due to long-time operation, aging and lack of maintenance, there are many problems in small reservoirs, especially the leakage of drainage tunnel, which seriously affects the normal function of reservoirs. Taking the Huzhu East reservoir in Tengzhou city, Shandong province as an example, the feasibility of various seepage prevention techniques for the drainage tunnel is expounded. Based on the cost-effectiveness, the optimal seepage prevention technique scheme that meets the application conditions of the reservoir is selected for reference

我国小型水库多建于20世纪50—70年代，工程标准低，质量较差，由于常年运行、老化失修、养护不足等原因，小型水库问题较多，其中放水洞渗漏尤为典型，严重影响水库正常功能的发挥。以山东省滕州市户主东水库为例，阐述多种放水洞洞身防渗处理技术的可行性，按照性价比，选择符合水库应用条件的最优防渗处理技术方案，可推广借鉴。
