Problems solved by technology

[0003] (1) The stability of the additional layer is poor, easy to collapse or collapse, even if the additional layer is fixed on the slope with anchor rods, barbed wire, etc., it is easy to collapse and collapse
Moreover, the amount of anchoring work is large and the cost is high.
[0004] (2) The thickness of the additional layer is generally very limited. Among them, the thickness of the sprayed nutrient layer is generally only about 10 cm, and its water retention and drought tolerance are poor. Even if a strong water-absorbing material is added as a water-retaining agent, it cannot resist for a long time. drought, and after a period of time, the water-retaining agent is easy to decompose or transform and lose its original strong water absor

Example Embodiment

[0016] Example 1: Use a rock drill to drill some deep holes with sufficient diameter on the slope. The distance between the holes is determined according to the length of the above-ground stems of the plant, which is generally greater than 2 meters. The diameter of the hole is determined according to the root system of the plant. Generally greater than 40 mm, the depth of the hole is also determined according to the root system of the plant, generally greater than 1 meter. Fill the drilled hole with a mixed nutrient mixture of soil, fertilizer, humus and water-retaining agent, and then plant a drought-tolerant and barren-tolerant climbing plant "Parthenocissus" in the borehole filled with the mixed nutrient. .

Example Embodiment

[0017] Embodiment 2: Use a drilling machine to drill some deep holes of sufficient diameter at a certain interval on the slope surface, the diameter of the drilled holes is greater than 40 mm, the interval is greater than 2 meters, and the depth is greater than 1 meter. Fill the borehole with a mixed nutrient mixture of soil, fertilizer, humus and water-retaining agent, and then plant the climbing plant ivy in the borehole filled with the mixed nutrient.

Abstract

The invention relates to a dome repairing method that drills some deep holes on the dome by jack hammer or drilling machine, adds mixture vegetation in it and plants climbing plant on it, and uses the haulm of the plants to cover the dome. The method has little engineering work load, and the nutritive layer is not easy to be swept away, and it could also fix the dome.

Description

technical field [0001] The invention relates to a greening method, in particular to a slope vegetation restoration method. Background technique [0002] In the prior art, there are generally two types of methods for vegetation restoration of rocky slopes. One is to artificially add a nutrient layer on the surface of the slope, such as sprayed adhesion layer, masonry layer, grid guest soil layer or geotextile felt, etc., and then Plant plants in this layer. Another type of method is to dig pits and grooves on the slope or side slope step surface, then backfill planting soil in the dug pits and grooves, and then plant plants therein. But these two methods are not suitable for vegetation restoration on high and steep rocky slopes. because: [0003] (1) The stability of the additional layer is poor, and it is easy to collapse or collapse. Even if the additional layer is fixed on the slope with anchor rods, barbed wire, etc., it is easy to collapse and collapse. And the engi...
