Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] figure 1 It is the general cross-section diagram of unstable earth-rock slope restoration, figure 2 is the construction diagram of the surface runoff interception ditch and the reinforcement wall at the top of the slope, image 3 It is a schematic diagram of the anchored net structure on the slope surface and the layered structure of guest soil spraying.

[0034] In a specific embodiment of the present invention, the surface runoff interception ditch 2 is excavated at the junction of the unstable earth-rock slope formed after the destruction and the undamaged background mountain 1 covered by vegetation, and a low slope top structure reinforcement wall is built. 3. Above the bare slope, there are mostly undamaged original mountains with good vegetation growth for a long distance. Although these mountains have obvious water and soil conservation capacity in th...

Abstract

The invention discloses an ecological restoration structured approach for an unstable earth and rockfill side slope, comprising the following steps: reinforcing a slope with iron threaded anchor rods and galvanized wire meshes; then restoring by a wet type spraying and sowing technique; further reducing loss soil loss tolerance of a sowing layer by the pore retaining effect of a three-dimensional vegetation network; constructing surface runoff retaining ditches and reinforcing walls at the joint of naked abrupt slopes and undamaged massifs to prevent the fall of the slope crest; constructing a collecting basin at the slope base to collect slope runoff and massif predominant current. The approach disclosed by the invention effectively realizes effective fixation of a plant matrix of the unstable earth and rockfill side slope, so that a restored vegetation layer can be formed in a short period of time and is not easy to be damaged; meanwhile as water power retention period increases, adaptability is good, the restored matrix does not run off easily.

Description

technical field [0001] The invention relates to an ecological restoration method for exposed mountain slopes, in particular to a plant-based restoration construction method for mountain exposed slopes with soil-rock mixed and unstable bases. Background technique [0002] In recent years, due to large-scale mining and road engineering and other construction projects, a large number of exposed rock and soil slopes have been formed, which are prone to water and soil erosion, mountain instability and landslides, environmental pollution, ecological imbalance, landscape destruction, microclimate changes, etc. Negative effect. Traditional slope restoration measures mostly adopt slope protection structures such as masonry walls and reinforced cement, which unilaterally consider the effect of inhibiting soil erosion, which does not improve the ecological environment, but destroys the harmony of the ecological environment. Under the environment of creating an environment-friendly soc...
