Example Embodiment

[0018] In the following, the present invention will be further explained in conjunction with the embodiments.

[0019] A method for vegetation restoration on highway side slopes in Qinghai plateau area, including the following steps,

[0020] (1) Slope cleaning: Remove dangerous rocks and floating soil on the slope, reduce the height and slope of the slope, and smooth the slope.

[0021] (2) Construction of anchor rods and nets: drill anchor holes with a horizontal distance of 1m and a distance of 2m along the slope. The direction of the hole is perpendicular to the slope surface, grouting in the hole, and the main anchor rod is inserted into the anchor hole until the grout overflows and hardens ;

[0022] Lay porous fiber rock wool from top to bottom along the slope. The porous fiber rock wool is provided with through holes at a horizontal spacing of 1m and a longitudinal spacing of 1m. The diameter of the through holes is equal to the diameter of the main bolt. The porous fiber rock...

Abstract

The invention discloses a method for repairing a slope of a highway in a Qinghai plateau area by using vegetation, which comprises the following steps of: (1), cleaning the slope; (2), constructing ananchor rod and a hanging net: drilling anchor holes at a horizontal interval of 1 meter and a downstream interval of 2 meters, and inserting a main anchor rod; laying porous fiber rock wool along theslope from top to bottom, and laying the hanging net on the porous fiber rock wool; (3), carrying out spray sowing of loam-like substrate, wherein the spray sowing of the loam-like substrate is carried out twice from top to bottom by using a spray sowing machine, wherein the thickness of the loam-like substrate is 7-9 centimeters in the first time of spray sowing; the thickness of the surface layer of the spray sowing of loam-like soil is 3-5 centimeters; (4), maintenance management. According to the method, the loam-like soil substrate suitable for plant growth in nature can be quickly simulated through a bionic method, so that the soil ventilation condition can be improved, the seed germination is facilitated, and the plant growth is promoted; The porous fiber rock wool is laid below the loam-like soil substrate layer to absorb water and maintain the water, and after natural rainfall or artificial irrigation, the porous fiber rock wool absorbs the water and maintains the water for being absorbed by the vegetation on the slope for a long time.

Description

technical field [0001] The invention relates to a method for restoring vegetation on road slopes in the Qinghai plateau area, and belongs to the technical field of ecological environment. Background technique [0002] In recent years, my country's road construction has achieved world-renowned achievements. However, during the construction of the road, a large number of new rock and soil are exposed and the vegetation is destroyed, causing serious damage to the surrounding environment along the line, aggravating soil erosion, and easily causing landslides and mudslides. and other geological disasters. Since 1996, the Kunqu Expressway began to adopt the form of vegetation restoration and reconstruction on the road slope to reduce soil erosion and restore the ecological environment. Since then, the expressway has become an ecological construction road. However, due to early blind restoration and limitations of technical means, the vegetation on some road slopes restored earlier...
