Dendritic embedded type flexible ecological slope drainage ditch and construction method
The invention discloses a dendritic embedded type flexible ecological slope drainage ditch and a construction method. The dendritic embedded type flexible ecological slope drainage ditch comprises permeable geotextile, an anti-seepage geomembrane, an anti-seepage clay layer, a sandy soil layer, a medium-coarse sand layer, a gravel layer, a small-particle-size gravel layer, a front water collectingand guiding ditch body, ditch top vegetation and a converging opening plugging structure. Drainage ditches serve as water collecting, intercepting and draining branch ditches and are arranged on twosides of a slope longitudinal main drainage ditch in a branch shape. The construction method comprises the following steps: designing a dendritic arrangement scheme on a slope; digging the drainage ditch; sequentially laying the permeable geotextile, the anti-seepage clay layer and the anti-seepage geomembrane; sequentially filling the in-ditch gravel layer, the medium-coarse sand layer, the sandysoil layer and the small-particle-size gravel layer in the front water collecting and guiding ditch body; and planting the ditch top vegetation. The technical bottlenecks that conventional intercepting and drainage ditches are prone to cracking and damage, poor in durability, poor in ecological property and the like are solved, and the drainage ditch has the advantages of being good in slope deformation coordination, low in material cost, high in intercepting and drainage capacity, environmentally friendly, ecological and the like, and has wide application prospects.
本发明公开了一种树枝状埋入式柔性生态的斜坡排水沟及施工方法，包括透水土工布、防渗土工膜、防渗黏土层、砂土层、中粗砂层、碎石层、小粒径碎石层、前置集导水沟体、沟顶植被和汇入口封堵结构。本发明排水沟作为集水、截水及排水支沟呈树枝状布置于斜坡纵向主排水沟两侧。其施工方法包括步骤：在斜坡上设计树枝状布置方案；开挖排水沟；依次铺设透水土工布、防渗黏土层、防渗土工膜；依次充填沟内碎石层、中粗砂层、砂土层和前置集导水沟体内小粒径碎石层；种植沟顶植被。本发明解决了常规截、排水沟易开裂破坏、耐久性差、生态性差等技术瓶颈，并且具有与坡体变形协调性好，材料成本低、截排水能力强、绿色生态等优点，具有广阔的应用前景。
