Anti-seepage structure of ecological river channel and construction method of anti-seepage structure
The invention discloses an anti-seepage structure of an ecological river channel. The anti-seepage structure comprises a river bottom anti-seepage structure and a side slope anti-seepage structure. The layer face structure of the river bottom anti-seepage structure is the same as that of the side slope anti-seepage structure, and the river bottom anti-seepage structure comprises a coarse sand cushion layer, a composite geomembrane, a fine-grained soil cushion layer, geotechnical cloth, a Reynolds protection cushion layer and a planting soil layer which are sequentially arranged from bottom to top. The thickness of the coarse sand cushion layer is 8-12 cm; the two ends of the composite geomembrane are embedded into anchoring grooves formed in the top faces of the side slopes on the two sides of the river channel correspondingly, and the anchoring grooves are filled with fine-grained soil in a backfilling mode and then compacted. The thickness of the fine-grained soil cushion layer is 20-40 cm; the two ends of the geotechnical cloth are embedded into the fine-grained soil cushion layers on the top faces of the side slopes on the two sides of the river channel correspondingly. The Reynolds protection pad layer is formed by assembling a plurality of cuboid Reynolds protection pad units; aquatic plants are planted on the planting soil layer. The invention further discloses a construction method of the anti-seepage structure of the ecological river channel. The anti-seepage water storage effect is good, construction is convenient, and a good ecological environment can be built.
本发明公开了一种生态河道的防渗结构，包括河底防渗结构和边坡防渗结构。河底防渗结构的层面结构与边坡防渗结构的层面结构相同并包括自下而上依次设置的粗砂垫层、复合土工膜、细粒土垫层、土工布、雷诺护垫层和种植土层；粗砂垫层的厚度为8～12cm；复合土工膜的两端各自嵌入开设在河道的两侧边坡顶面上的锚固槽内，并在锚固槽内回填满细粒土后压实；细粒土垫层的厚度为20～40cm；土工布的两端各自嵌入河道的两侧边坡顶面上的细粒土垫层内；雷诺护垫层由多个呈长方体的雷诺护垫单元组装而成；种植土层上栽种水生植物。本发明还公开了一种生态河道的防渗结构的施工方法。本发明的防渗蓄水效果好，施工方便，并能营造良好的生态环境。
