Problems solved by technology

[0003] At present, the domestic and international reconstruction of waste dumps in production and development zones only considers the number of species of plants to be restored, and the self-recovery of the ecosystem is often relatively slow, although short-term artificial irrigation and management and protection can be improved to a certain extent. Vegetation survival rate, but in northern China, especially grassland areas in arid and semi-arid areas, the soil is poor, the climate is dry and water-short, and the vegetation in the traditional restoration method will soon degrade and die after being separated from artificial management such as irrigation and fertilization. , causing secondary soil erosion

Embodiment 1

[0037] The slope vegetation restoration structure of a semi-arid dump site that utilizes precipitation efficiently in this embodiment includes a slope 1, and a reverse slope intercepting ditch 2 for planting vegetation is excavated on the slope 1, and the reverse slope There are several water intercepting ditches 2 arranged sequentially along the inclination direction of the side slope 1 , and a permeable pipe 3 is buried under the reverse slope water intercepting ditches 2 .

[0038] In this embodiment, by excavating the reverse slope intercepting ditch on the side slope, the reverse slope intercepting ditch can be used to intercept rainwater, irrigation water, snow water or other source water, and penetrate into the permeable pipe below the intercepting ditch, Water can be collected efficiently, and the collected water can be used to provide sufficient water supply to the vegetation that is out of human management and protection, avoiding the restoration of vegetation degradat...

Embodiment 2

[0040] Such as figure 1 As shown, the slope vegetation restoration structure of a semi-arid dump site that utilizes precipitation efficiently in this embodiment includes a slope 1, and an anti-slope intercepting ditch 2 for planting vegetation is excavated on the slope 1, so There are several anti-slope intercepting ditches 2 arranged sequentially along the inclination direction of the side slope 1 , and permeable pipes 3 are buried under the anti-slope intercepting ditches 2 .

[0041] Such as Figure 1-Figure 4 As shown, the reverse slope surface 21 of the reverse slope intercepting ditch 2 in this embodiment is arranged at an angle to the slope surface of the side slope 1 and extends out of the slope surface of the side slope 1 . On the one hand, it can increase the area of ​​the reverse slope, and on the other hand, it can also collect water into the reverse slope intercepting ditch to avoid loss from the slope surface.

Abstract

The invention relates to a semi-arid waste dump side slope vegetation restoration structure and method capable of efficiently utilizing rainfall. The restoration structure comprises a side slope, a plurality of reverse slope intercepting ditches used for planting vegetation are excavated in the side slope, the reverse slope intercepting ditches are sequentially arranged in the inclination direction of the side slope, and permeable pipes are buried below the reverse slope intercepting ditches. The reverse slope intercepting ditches are excavated in the side slope, rainwater, irrigation water, snow water or water from other sources can be intercepted through the reverse slope intercepting ditches, the rainwater, the irrigation water, the snow water or the water from other sources permeates into the water permeable pipes below the intercepting ditches, water can be efficiently collected, the collected water can be fully supplied to vegetation without manual management and protection, secondary water and soil loss caused by vegetation degeneration and death restoration is avoided, the semi-arid waste dump side slope vegetation restoration structure has important practical significance on waste dump slopes of production and construction projects in arid and semi-arid regions, green mine construction can be effectively promoted, and efficient and sustainable energy supply in China is guaranteed.

Description

technical field [0001] The invention relates to the technical fields related to efficient water collection and utilization and vegetation restoration, and in particular to a semi-arid dump site slope vegetation restoration structure and method for efficiently utilizing precipitation. Background technique [0002] The development and utilization of coal resources, while promoting economic and social development, has also brought a series of ecological and environmental disasters. Open-pit mining has caused severe disturbance to the surface, and the soil in the dump site formed by the accumulation of a large number of stripped objects is barren. In addition, during the process of dumping the soil, heavy trucks rolled over the surface and severely compacted the surface, which made it difficult for plants to take root, and a large amount of surface runoff was formed under rainfall conditions. Due to the non-uniform settlement of the dump site, settlement cracks are formed. After...
