Problems solved by technology

However, this method is only suitable for slopes with a slope of less than 70°. When the slope is steep, it is difficult for the sprayed plant material to adhere to the slope, and it is easily washed away by heavy rain, resulting in project failure.

Embodiment 1

[0020] A steep rock slope in Guangzhou with a slope greater than 70°C.

[0021] After a certain specification of metal cages, stones, geotextiles, and planting soil are twisted and filled to form a retaining wall with planting troughs, plants are planted in the planting troughs to achieve support and greening. The combined effect. It is a new type of protective structure that combines support and greening. Different from the traditional rigid structure (concrete, mortar and masonry), it has the characteristics of water permeability, durability, flexibility, high construction efficiency, environmental protection and good greening effect. It is especially suitable for landscape construction.

[0022] The specific method is as follows:

[0023] 1. Metal cage 1, its structure is like figure 1 Shown: The size of the net cage adopts length×width×height=2m×1m×1m, including the front panel 11, the rear rear panel 14, the left and right end plates 12 and the upper mesh cover plate 13, and t...

Abstract

The invention discloses a quick ecological rehabilitation method for a steep rock slope. The quick ecological rehabilitation method comprises the following steps of: manufacturing metal net cages; filling stones in the metal net cages, wherein the particle size of each stone is required to not be smaller than the size of grids of each metal net cage; setting a planting groove in the upper surface layer of the stones; paving a layer of geotextile on the surface of the planting groove and then filling planting soil in the planting groove; covering net cover plates of the metal net cages; stacking the metal net cages on a foundation trench of the steep rock slope layer by layer from low to high; and connecting the metal net cages in a twisting way; and planting plants in the planting groove and conventionally curing the plants. The quick ecological rehabilitation method is a method for combining the metal net cages with planting groove afforestation, and thereby the aims of quickly protecting the slope and realizing the ecological rehabilitation effect are achieved; different from a traditional rigid structure (concrete and stone masonry), the quick ecological rehabilitation method has the characteristics of water permeability, durability, flexibility, high construction efficiency, environment friendliness, favorable afforestation effect and the like and is especially suitable for landscape construction.

Description

Technical field: [0001] It belongs to the field of slope ecological restoration, and specifically relates to a method for rapid ecological restoration of steep rock slopes. Background technique: [0002] With the rapid advancement of social and economic construction, human beings have built large-scale construction projects on the homes on which they depend, opened mountains and land, built roads and bridges, and built houses and factories. These projects have provided human beings with the necessary conditions for survival, but at the same time they have also destroyed the big The original ecological balance of nature. During the construction of highways, railways, water conservancy, electric power, mines and other projects, a large number of excavations and fillings are often required, forming a large number of exposed slopes. Bare slopes will bring a series of environmental problems, such as soil erosion, landslides, mudslides, deterioration of local microclimate and destruct...
