Abstract Taking the third phase of Jingcheng Expressway as an example, this paper describes a slope vegetation restoration technology, i.e., multi-step slope recovery technology, which combines the external-soil spray seeding technique and the substrate spray technology. The technology uses the cutting machine to convert the steep slope to a multi-stage slope with a certain ratio of height to width. Revetment network is set along the stepped surface and matrix of plant species is sprayed on each slope. At the same time, we borrow soil on each slope and spay seeds of trees and shrubs to ensure slope stability, improve the success rate of vegetation recovery, and realize slope vegetation restoration and greening. This technology has advantages of stabilizing slopes, reducing soil erosion and beautifying the environment. It can provide reference for similar construction of slope recovery vegetation.
