Embodiment 1

[0028] Such as Figure 1-Figure 5 As shown, Embodiment 1 of the present invention provides a method for greening a steep rock slope of a mine, which includes the following steps:

[0029] Step S1: Place slope 1 at a stable slope angle. When slope 1 is relatively high, slope 1 adopts multi-stage grading;

[0030] Step S2: excavate the top intercepting ditch 2 along the top of the slope 1, excavate the bottom drainage ditch 3 along the toe of the slope 1, and on the slope surface between the top intercepting ditch 2 and the bottom drainage ditch 3 Several rows of slope planting troughs 4 were excavated on the top, and the slope planting troughs 4 were arranged in parallel at a distance of 5m-10m. The upper and lower ends of the slope planting trough 4 were connected to the slope top intercepting ditch 2 and the slope toe drainage ditch respectively 3. Slots 41 are opened in the slope planting groove 4 at a certain interval (can also be left, the groove (ridge) is not less than 50mm ...

Embodiment 2

[0037] Such as Figure 1-Figure 5 As shown, embodiment 2 of the present invention provides a method for greening a high-steep rock slope 1 in a mine. The steps of the method are basically the same as those of embodiment 1, except that step A1 is included between step S3 and step S4. : Lay geotextile 9 in the soil tank. By laying the geotextile 9 in the soil tank, it is possible to prevent the planting soil 7 in the soil tank from being lost from the gap between the prefabricated partition 6 and the slope planting tank 4.

Embodiment 3

[0039] Such as Figure 1-Figure 5 As shown, embodiment 3 of the present invention provides a method for greening a high-steep rock slope in a mine. The steps of the method are basically the same as those of embodiment 1, except that step S2 and step S3 further include step B1: A plastic drainage board 10 is laid along the slope planting groove 4, and the plastic drainage board 10 is attached to the bottom of the planting groove 4 on the slope. The plastic drainage board 10 has the function of guiding seepage water. By laying the plastic drainage board 10 on the bottom of the slope planting trough 4, the seepage effect of irrigation water can be improved, even the planting soil 7 near the slope toe can be better. Compared with the traditional irrigation methods of seepage pipe and drip irrigation pipe, the cost of the plastic drainage board 10 is lower and the construction is more convenient.

Abstract

The invention discloses a mine high and steep rock slope greening method. The method includes the following steps of arranging a slope according to a stable slope angle, digging a slope top water intercepting groove in a slope top, digging a slope foot water drainage groove in a slope foot, digging a slope surface planting groove in a slope surface, connecting the upper end and the lower end of the slope surface planting groove into the slope top water intercepting groove and the slope foot water drainage groove respectively, forming slots in the slope surface planting groove, digging a slopesurface water drainage groove in the slope surface, forming an overflow opening in the slope top water intercepting groove, connecting the upper end of a water drainage groove with the overflow opening, connecting the lower end of the water drainage groove into a slope foot drainage groove, inserting prefabricated partition plates in the slots of the slope surface planting groove respectively so that soil containing grooves can be formed between the upper surfaces of the prefabricated partition plates and the slope surface planting groove, filling the soil containing grooves with planting soil, and planting various vegetations on the planting soil in the soil containing grooves. The construction difficulty and construction cost are reduced, the natural irrigation problem of the vegetationson the slope is solved, and meanwhile the influences of loads, rainwater and irrigation water on the slope stability are reduced.

Description

Technical field [0001] The invention relates to the technical field of side slope ecological restoration, in particular to a greening method for high and steep rock slopes in mines. Background technique [0002] With the structural adjustment of China’s economy from focusing on quantity to improving quality, the mine sites left over by over-exploitation in the past are devastated. Although they cannot be restored and greened as before, through innovation and improvement of the greening plan, it can also be achieved by adapting measures to local conditions. Mountain effect. [0003] For rocky slopes with hard geology, there are two main methods for greening the slope: one of them is to only vegetation on the slope or under the slope (such as Chinese patent CN104196040B), and only the climbing vines at the foot of the slope. Plants grow randomly to cover, it takes a long time, and the effect is not ideal; another approach is to set up a flower stand on the slope of the side slope, t...
