Double-layer geomembrane core wall rock-fill dam structure and construction method
The invention relates to a double-layer geomembrane core wall rock-fill dam structure and a construction method, and aims to provide the double-layer geomembrane core wall rock-fill dam structure withexcellent anti-seepage performance and reliability and the construction method. According to the technical scheme, the double-layer geomembrane core wall rock-fill dam structure is characterized in that a double-layer geomembrane anti-seepage core wall structure body is arranged inside a rock-fill dam; and the double-layer geomembrane anti-seepage core wall structure body is sequentially providedwith an upstream sand cushion layer, an upstream geomembrane, a middle silt layer, a downstream geomembrane and a downstream sand cushion layer from upstream to downstream. The double-layer geomembrane core wall rock-fill dam structure is applicable to the field of water conservancy and hydropower engineering.
本发明涉及一种双层土工膜心墙堆石坝结构及施工方法。本发明的目的是提供一种具有优越防渗性能和可靠性的双层土工膜心墙堆石坝结构及施工方法。本发明的技术方案是：一种双层土工膜心墙堆石坝结构，其特征在于：该堆石坝内具有双层土工膜防渗心墙结构体；所述双层土工膜防渗心墙结构体从上游至下游依次设有上游砂垫层、上游土工膜、中部粉土层、下游土工膜和下游砂垫层。本发明适用于水利水电工程领域。
