Problems solved by technology

[0003] For a long time, as an important part of the rock ecological management, the sandification restoration project of the gneiss surface has become a part that cannot be ignored in the greening design. The treatment effect achieved by the sandification restoration project on the surface of gneiss is still not ideal, and the investment in treatment is relatively large

specific Embodiment 1

[0025] The present invention is a method for repairing sandy surface of gneiss rock, comprising the following steps:

[0026] Step 1: Clean up the sundries and loose rocks on the surface of the gneiss; use a hammer to repair the particularly protruding places on the gneiss surface to make it flat; use crushed stones and adhesives for the particularly concave places The mixture is filled and watered and moistened;

[0027] Step 2. Divide the gneiss surface into several areas according to the slope grade, and drill holes in the gneiss surface area in a linear array according to the grade of the surface slope of the photo; the hole depth is 15cm, the aperture is 20cm, and two adjacent holes The distance between them is 120cm;

[0028] Step 3. Insert the wooden protective pile vertically into the hole. The diameter of the protective pile is 4cm; : 1:2 ratio is mixed and filled in the hole, and then watered and moistened;

[0029] Step 4. According to the gradient grade of the s...

Abstract

The invention discloses a repair method for gneiss surface desertification, and belongs to the technical field of desertification repair. The method comprises the following steps: cleaning out sundries and loose rocks on the surfaces of gneiss; carrying out drilling on surface areas of the gneiss according to the gradient grade of the surfaces of the gneiss; vertically inserting wood protection piles into holes, mixing gravel, local mellow soil, a water-retaining agent and an adhesive according to a certain ratio, and then filling holes with the obtained mixture; laying a gauze net with a correspond mesh density; mixing local mellow soil, peat soil, a compound fertilizer, a curing agent and a water-retaining agent according to a certain ratio and then spraying the obtained mixture into thegauze net; carrying out corresponding greening operation on the surface areas of the gneiss; and carrying out maintaining management. According to the method, partition greening operation is carriedout according to different gradient grades of the surfaces of the gneiss, so that the water and soil loss rate of the surfaces of the gneiss is greatly reduced, occurrence of dangerous accidents suchas soil weathering, debris flow and the like is reduced, and the risk of continuous desertification of the surface of the gneiss is avoided.

Description

technical field [0001] The invention belongs to the technical field of sandification restoration, in particular to a method for sandification restoration of gneiss surface. Background technique [0002] At present, with the rapid development of the mountain economy, various engineering construction projects are constantly advancing. Mountain highways, water conservancy and hydropower projects, and municipal construction have formed a large number of rocks. Due to poor water retention and relatively barren rock quality, it is difficult to provide the necessary matrix conditions for vegetation growth. Therefore, the ecological management technology of rock is more difficult. [0003] For a long time, as an important part of the rock ecological management, the sandification restoration project of the gneiss surface has become a part that cannot be ignored in the greening design. Gneiss surface sandification restoration project achieves unsatisfactory treatment effect, and th...
