Method for repairing slope vegetation

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...

AI Technical Summary

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 absorption, which will cause the planted plants to dry out

[0005] (3) The root system of the plants on the additional layer is difficult to go deep into the slope rock, so it cannot play the role of stabilizing the slope

On the contrary, if a tree is planted, once its roots go deep into the cracks of the rock, it will burst the rock and reduce the stability of the slope when it grows thick.

[0006] (4) Digging pits and grooves on inclined slopes to create a nutrient bed for plant growth is not only difficult for construction, but also seriously damages the stability of the slope

If the slope is arranged into a step shape, and then pits and grooves are dug on the step surface to plant plants, it will greatly increase the amount of excavation and spoil
