Earth and rockfill dam ballasting body terrain reshaping ecological protection structure and construction method
The invention discloses an earth and rockfill dam ballasting body terrain remodeling ecological protection structure in the technical field of hydraulic engineering, which comprises a stone-in-soil heaping body arranged on the downstream side of a dam, and an inverted filter layer is arranged at the bottom of the stone-in-soil heaping body. The inverted filter layer comprises inverted filter geotechnical cloth, an upper-layer inverted filter material and a lower-layer inverted filter material, the upper-layer inverted filter material and the lower-layer inverted filter material are laid on the upper side and the lower side of the inverted filter geotechnical cloth respectively, the particle size of the lower-layer inverted filter material is smaller than that of the upper-layer inverted filter material, a soil covering layer is arranged at the top of the soil-rock heaping body, and green plants are planted on the soil covering layer. Through the arrangement of the downstream dam ballasting body terrain shaping and ecological restoration structure, on one hand, the anti-seepage capacity of the downstream dam ballasting body is improved, drainage and safety are guaranteed, and water and soil loss is avoided; on the other hand, basic conditions for vegetation growth are created, the ecological environment is considered, the project quality is ensured, meanwhile, an ecological, comfortable and beautiful power station environment can be created, and the comprehensive benefits of the power station are exerted to the maximum extent.
本发明公开的是水利工程技术领域的一种土石坝大坝压重体地形再塑生态防护结构，包括设置在大坝下游侧的土夹石堆筑体，所述土夹石堆筑体的底部设有反滤层，反滤层包括反滤土工布和分别铺设在反滤土工布上下两侧的上层反滤料和下层反滤料，且下层反滤料的粒径小于上层反滤料的粒径，土夹石堆筑体的顶部设有覆土层，覆土层上种植有绿化植物。本发明通过下游大坝压重体地形塑造及生态恢复结构的设置，一方面增加了下游坝压重体的防渗能力，保证排水及安全性，避免水土流失；另一方面创造了植被生长的基本条件，兼顾了生态环境，在确保工程质量的同时，能营造一个生态、舒适、优美的电站环境，最大程度发挥电站的综合效益。
