Dry spraying and wet spraying combined vegetation concrete ecological restoration method for high and steep slope
The invention provides a dry spraying and wet spraying combined vegetation concrete ecological restoration method for a high and steep slope, which is characterized in that on the basis of the original dry spraying vegetation concrete technology, spray-seeding is improved into three layers, namely a base layer, a surface layer and a protective layer, the surface layer is constructed by adopting a dry spraying machine, and the base layer and the protective layer are constructed by adopting a wet spraying machine; on the basis of an original dry spraying vegetation concrete formula, the cement consumption is reduced, and the integrity and adhesiveness of a base material are maintained by adding tree fibers, polyvinyl alcohol and fly ash; the protective layer is a mixture of pure tree fibers and polyvinyl alcohol, replaces coverage of non-woven fabrics, has the characteristics of water retention, heat preservation, air permeability and the like, and provides anti-scouring capacity for the base material in the early stage of spray seeding; the coated slow-release compound fertilizer is adopted to replace part of common compound fertilizer, nutrients are provided for a long time in the base material, and the later-period nutritional condition of the base material is improved; the shrub seeds are mixed and put into the base layer, and the herbal seeds are mixed and put into the surface layer.
本发明提供了用于高陡边坡干喷湿喷结合的植被混凝土生态修复方法，在原有干喷植被混凝土技术的基础上，将喷播改进为三层，分别为基层、面层以及防护层，面层采用干喷机施工，基层以及防护层采用湿喷机施工；在原有干喷植被混凝土配方的基础上降低水泥用量，加入树木纤维、聚乙烯醇以及粉煤灰维持基材的整体性和附着性；防护层为纯树木纤维和聚乙烯醇的混合物，代替无纺布的覆盖，具有保水性、保温性、透气性等特点，为基材喷播初期提供抗冲刷能力；采用包膜缓释复合肥代替部分普通复合肥，在基材内部长效提供养分，改善基材后期营养状况；灌木种子混合放入基层中，草本种子混合放入面层中。
