Hetaoyu Dam Seepage Treatment Design and Construction in Feixian

摘要:

临沂市费县核桃峪塘坝库区及库区周边区域岩体岩溶较发育，坝基上下游形成了渗漏通道。通过对库区水文地质条件的分析研究，结合生态治理理念，提出了库底与库岸截渗的处理措施，综合土工膜、壤土防渗、逆止阀的合理运用，在工程实施后，防渗效果明显。

Abstract:

The Karst development of rock mass in Hetayu reservoir area and its surrounding area in Feixian County of Linyi Municipality, has formed seepage channels in the upper and lower reaches of dam foundation. With the concept of ecological management, and based on the analysis and study of the hydrogeological conditions of the reservoir area, this paper puts forward the treatment measures of seepage intercepting between the bottom and the bank of the reservoir. The rational use of geomembrane, loam seepage prevention and check valve is integrated, and the anti-seepage effect is obvious after the implementation of the project.
