Problems solved by technology

[0002] With the rapid development of my country's infrastructure projects, many high and steep rock slopes have appeared, and the natural vegetation has lost the site conditions for recovery, making the ecological self-repair long and uncertain, which intensifies the occurrence of soil erosion and natural disasters , while destroying the ecological environment, it also causes a certain visual impact on the landscape
Especially in the high-latitude cold regions of my country, the climate is cold and the growth period of vegetation is short. If the method of regreening is not used properly, problems such as freeze-thaw erosion of the base material and failure of vegetation to survive will occur. certain influence

Embodiment 1

[0028] Include the following steps:

[0029] (1) Mix the sandy and gravel-containing surface soil stripped from the project area with organic fertilizer and peat soil and use it as a greening substrate;

[0030] (2) Slope surface treatment: Firstly, use manual work to clean the floating soil, pumice and weeds on the rocky slope surface, especially scattered gravel, and then use water cannons to wash the slope surface to remove the floating soil or debris on the slope surface that has not been cleaned. thing;

[0031] (3) Planting holes on the slope surface: planting holes are drilled on the rock slope according to the quincunx-shaped layout (see 3 figure 1 ), fill the greening substrate 7 after removing the rock debris in the hole, and insert a 30cm long steel bar in each hole, so that the head of the steel bar is exposed 15cm outside the hole, so that the planting hole position cannot be found after preventing spraying;

[0032] (4) Lay galvanized wire mesh: wrap straw 5 wi...

Embodiment 2

[0049] Include the following steps:

[0050] (1) Mix the topsoil containing sand and gravel stripped from the project area with organic fertilizer and peat soil and use it as a greening substrate;

[0051] (2) Slope surface treatment: Firstly, use manual work to clean the floating soil, pumice and weeds on the rocky slope surface, especially scattered gravel, and then use water cannons to wash the slope surface to remove the floating soil or debris on the slope surface that has not been cleaned. thing;

[0052] (3) Planting holes on the slope surface: planting holes are drilled on the rock slope according to the quincunx-shaped layout (see 3 figure 1 ), fill the greening substrate 7 after removing the rock debris in the hole, and insert a 32cm long steel bar in each hole, so that the head of the steel bar is exposed 17cm outside the hole, so that the planting hole position cannot be found after preventing spraying;

Abstract

The invention belongs to the technical field of ecological slope protection and relates to a rock slope ecological restoration method for high-latitude severe cold regions. The method includes greening base material preparation, slope surface treatment, planting hole punching and galvanized wire mesh laying on the slope surface, spray seeding construction, planting of radical buds of shrub and herbaceous plants and maintenance. High-gravel-content large-particle surface soil stripping in an engineering area is adopted for rock slope greening, and by further planting of the radical buds of shrub and herbaceous plants in slope planting holes, regional landscape effects are rebuilt while quick ecological restoration is realized. The method is simple, convenient, high in operability and low incost, local waste recycling can be realized, and accordingly environmental pollution is abated. By vegetation community formed after spray seeding according to the method, rock slope vertical greening with arbor, shrub and herbaceous plants in the high-latitude severe cold regions is truly realized, durable attachment of a slope base material is realized, an unattended state is truly achieved after vegetation lawn formation, and regional landscapes are recovered quickly while the plant community adapting to local natural conditions is formed.
