Embodiment
[0047] Taking the 3# slope of Fujian Yongtai Pumped Storage Power Station as an example to illustrate the specific construction steps of the vegetation slope protection structure:
[0048] (1) The multifunctional bag is mechanized into a rectangular degradable fiber web. According to the slope conditions, its length is 2000mm, its width is 100mm, and its height is 80mm. The multifunctional bag is filled with arbors and irrigation suitable substrates, and the seeds of arbors and shrubs are embedded in holes in proportion. The ratio of the base material is: 1000 parts by weight of planting soil, 300 parts by weight of rice husk, 50 parts by weight of vegetation concrete active additive, 50 parts by weight of organic fertilizer and 10 parts by weight of compound fertilizer. According to the characteristics of the arbor selected for vegetation slope protection, plant holes on the multi-functional bag according to the requirements of 800mm spacing and bury the seeds of Amorpha fru...

Abstract
The invention discloses a vegetation based slope protection structure and a construction method thereof. The vegetation based slope protection structure comprises a slope side distributed with a plurality of multifunctional bags; a hanger net is arranged above the multifunctional bags; the multifunctional bags are fixed to the slope side through anchoring nails, or are fixed to the net meshes andthen the net meshes are fixed to the slope side through anchoring nails; a vegetation slope-protection base layer is arranged between the hanging net and the slope side, and a vegetation slope-protection face layer is arranged on the side away from the slope side; the multifunctional bags are of stereoscopic structures made of nets by encircling, and filled with basic materials and seeds of treesor bushes, and the distance between the hanging net and the slope side is 80 to 100 mm. The vegetation based slope protection structure and the construction method thereof solve the problems that thedistance between the meshes and the slope side seldom meet the design requirements during construction of the vegetation based slope protection and it is impossible to realize symplastic growth of grass, trees and brushes in the vegetation based slope protection, and have a great significance in ecological protection engineering of slopes.
Description
technical field [0001] The invention belongs to the technical field of slope ecological protection engineering, and in particular relates to a vegetation slope protection structure and a construction method thereof; in the slope ecological protection engineering, a multifunctional bag for vegetation slope protection is provided, which can be used without affecting the engineering slope protection To improve the durability and species diversity of vegetation slope protection. Background technique [0002] With the country's emphasis on environmental issues, the connotation of environmental protection has been added to the discipline of geotechnical engineering. Vegetation restoration technology on the excavated surface of rock and soil, and the rational use of waste residue have become the research fields of geotechnical and ecological environment engineering. hotspots. Various ecological slope protections emerged as the times require, and the use of vegetation to protect sl...
