High and steep gravelly soil slope ecological restoration structure system and restoration method

Abstract

The invention discloses an ecological restoration structure system and method for a high and steep gravelly soil slope. The slope of the ecological restoration structure system is divided into an upper area, a middle area and a lower area from top to bottom. The upper area is sequentially provided with a cushion layer and a spray-seeding surface layer from the original ground line to the outside, the spray-seeding surface layer is formed in a spray-seeding mode, and shrub seeds and grass seeds are arranged in the surface layer; a transverse drainage ditch and a plurality of holes are formed in the slope surface of the middle area, and shrub seedlings and grass seedlings are planted in the holes in a hill-seeding mode; the lower area is provided with a boulder accumulation layer, a plant-growing bag layer is arranged on the boulder accumulation layer, and vines and shrubs are planted in the plant-growing bag layer in a cuttage mode; and a transversely arranged retaining wall is arranged at the slope toe of the lower area. The problems that high and steep slope repairing construction is difficult, and the effect is slow are solved.

Description

technical field [0001] The invention relates to an ecological restoration structure system and restoration method of high and steep gravel soil slopes, belonging to the field of slope greening and ecological restoration. Background technique [0002] The applicant has carried out the project establishment, scientific research, and construction of test plots of the "Study on the Three Simultaneous Management System and Key Technologies of Water and Soil Conservation in Southern Mountain Wind Farms", among which the key technology is the research on the ecological restoration system of high and steep gravel fill slopes. For the high and steep dregs and gravel soil slopes formed by the excavation of field roads and wind turbine platforms, a comprehensive ecological restoration system has been developed to control soil and water loss on the slope, and finally achieve the self-sustainment and virtuous cycle of the dregs slope ecosystem, and establish 1 test area. [0003] The ha...

AI Technical Summary

Problems solved by technology

Therefore, the measure system of CN102444134B is only applicable to common fill slopes, and cannot solve high and steep slag-hanging slopes

[0005] Chinese invention patent application CN110622643A discloses an ecological restoration method for rocky slopes in high-latitude severe cold regions. This ecological restoration method is suitable for rocky excavated slopes. The characteristics of this type of slope are poor site conditions, steepness, However, the slope is in a stable state, and there is no need to take slope stabilization measures

At the same time, the measures of CN110622643A are mainly measures such as slope planting holes and slope dough particle spraying. The operation platform, the secondary excavation disturbs the surface to cause water and soil loss

Therefore, the CN110622643A measure system is only applicable to rocky excavation slopes, and cannot solve the problem of high and steep slag-hanging slopes.

[0006] Chinese utility model patent CN214169088U discloses a vine greening structure applied to the ecological restoration of high and steep rocky slopes. It is suitable for rocky excavated slopes. The slope is in a stable state, no slope stabilization measures are required

Simultaneously, the measure of CN214169088U patent is mainly the method for the vine greening side slope of the vine greening side slope that vegetation bag cuttage plant is set horizontally on the slope surface, and climbing net is set on the slope surface. Moreover, drilling holes on the slope is difficult and costly

Therefore, CN214169088U measure system is only applicable to rock excavation slope, can't solve high and steep dregs slope (fill slope)
