Abstract

The invention discloses a method suitable for ecological restoration of a concrete spraying side slope. A construction structure comprises a concrete spraying layer, an isolation layer, a galvanized metal net, a nutrition matrix layer, an ecological water and soil protection blanket and a spraying medium layer, wherein the isolation layer is a material layer which neutralizes alkali released by the concrete spraying layer and isolates the alkalinity from diffusing, the isolation layer is tightly attached to the concrete spraying layer, the galvanized metal net is laid and hung on the surface of the isolation layer and is fixed through anchor rods, the nutrition matrix layer is arranged on the galvanized metal net, the ecological water and soil protection blanket is laid on the nutrition matrix layer and is fixed through U-shaped anchor nails, the spraying medium layer is arranged on the ecological water and soil protection blanket, and nursery stocks are planted. According to the method, the construction problems of vegetation planting and ecological restoration of the concrete spraying side slope in an existing soil dressing spray-seeding technique are solved, and the influence of alkali release of the concrete spraying layer on plant growth can be effectively inhibited.

Description

technical field [0001] The invention relates to the technical field of slope ecological restoration, in particular to a method suitable for the ecological restoration of sprayed concrete slopes. Background technique [0002] Due to the need for safety protection, construction projects such as water conservancy and hydropower often use concrete anchor spraying to protect the damaged slope and form a sprayed concrete slope. Although this physical protection method can prevent secondary disasters such as slope instability, collapse, gravel slide, and debris flow, it also makes it more difficult to restore vegetation on the damaged slope of the project, which is a typical type of difficult site. Under such site conditions, plant growth is limited and ecological restoration is difficult, which brings a series of ecological and environmental problems. The specific manifestations are: (1) the biological chain is cut off, which isolates the microcirculation system of soil gas and w...
