Construction method and process of sponge body for repairing water ecological environment
The invention discloses a cavernous body construction method and process for repairing a water ecological environment, and the method comprises the following steps: S1, carrying out plain soil compaction on a construction area, laying a permeable geotextile on the compacted ground, S2, installing a PVC perforated drain pipe, and laying a gravel layer in the construction area, S5, laying the permeable geotextile again, S3, stacking a soil changing layer on the top of the permeable geotextile, wherein a medium-coarse sand leveling layer is laid on the top of the soil changing layer, water-permeable geotextile is laid on the top of the medium-coarse sand leveling layer, and a PP rainwater module is installed on the top of the water-permeable geotextile; and S4, laying planting soil, wherein greening vegetation is planted. According to the construction method and process of the cavernous body for repairing the water ecological environment, the lower cushion layer composed of the permeable modules wrapped by the sand, the gravel and the geotechnical cloth and the seepage guide columns penetrate into the underground soil layer, seepage rainwater can be filtered, gravel holes are filled with air, gas-liquid exchange can be effectively formed in the rainwater seepage process, and the rainwater seepage speed is increased. Underground water is supplemented.
本发明公开了一种修复水生态环境海绵体施工方法与流程，包括以下步骤：S1：对施工区域进行素土夯实，在经过夯实后的地面铺设透水土工布，S2：安装PVC穿孔排水管，在施工区域铺设砾石层，S5：再次铺设透水土工布，S3：在透水土工布的顶部堆放换土层，在换土层的顶部铺设中粗砂找平层，在中粗砂找平层的顶部铺设透水土工布，在透水土工布的顶部安装PP雨水模块，S4：铺设种植土，种植绿化植被。本发明所述的一种修复水生态环境海绵体施工方法与流程，通过由砂、碎石和土工布包裹透水模块组成的下垫层，以及导渗柱，深入地下土层，能过滤下渗雨水，碎石孔隙充满空气，在雨水下渗过程中能有效形成气液交换，加快雨水下渗速度，补充地下水。
