Problems solved by technology

[0004] Aiming at the defects in the background technology, the present invention proposes a method for ecological restoration of steep rock slopes by using a soil-fixing cage, which can not only effectively maintain water and soil, prevent the foreign soil layer from falling off, but also improve the ability of the foreign soil layer to withstand rain erosion , it also effectively solves the problem of necessary nutrient exchange for plant growth, provides a stable growth platform and growth environment for plants, and the implementation method is simple and easy, and the cycle is short, which can be well applied in the ecological restoration process of rocky steep slopes middle

Embodiment 1

[0031] Such as figure 1 , 2 , Shown in 3, a kind of adopting soil-fixing cage of the present invention carries out method and soil-fixing cage to rock steep slope ecological restoration, the method may further comprise the steps:

[0032] 1. Clean up the slope: clean up the loose pumice on the slope of the rocky slope to remove potential safety hazards and ensure the safety of construction on the rocky slope;

[0033] 2. Fix the cross structure: select a flat place on the rock slope to place the grooved steel pipe ten cross structure 2 three-dimensionally, and then drive a diameter of 8mm-12mm and a length of 40mm at the center of the upper end of the cross structure 2 away from the slope. Anchors 1 of -50cm, and ensure that the cross structure is roughly perpendicular to the slope, and then fix the next cross structure at a distance of 30-40cm vertically and horizontally around the center of the fixed cross structure;

[0034] 3. Make the board: the board is made of HDPE bo...

Embodiment 2

[0040] Such as figure 1 , 2 , shown in 3, a kind of adopting soil-fixing cage of the present invention carries out method and soil-fixing cage to rock steep slope ecological restoration, this soil cage soil cage is set to cuboid shape, and its long 30-40cm, wide 30cm -40cm, 15-20cm high, with holes staggered around each other; it consists of three parts: HDPE board, cross structure and barbed wire.

[0041]The thickness of HDPE board is 1-2cm. It has heat and cold resistance, stable chemical properties, and high rigidity and toughness. The surface fits the shape of the lower part, so that it fits closely with the high and steep rock slope, and there will be no suspension phenomenon, and it is ensured that the soil-fixing cage fixed on the slope surface is on the same plane; in the two perpendicular plates Two holes with a diameter of 2-4cm are respectively opened, but the plates where the holes are located cannot be parallel to each other, so as to exchange nutrients such as...

Abstract

The invention relates to a method for performing ecological restoration on a steep rock slope through a soil fixing cage. The ecological restoration method comprises the following steps of (1) cleaning of the slope surface; (2), fixing of cross structures; (3), fabrication of plates; (4), installation of soil fixing grids; (5), laying of iron wire nets to form the soil fixing cage; (6), ejecting of foreign soil and sowing; (7) maintenance. The soil fixing cage is a cuboid composed of the prefabricated HDPE plates, the cross structures and the iron wire nets and is provided with holes staggeredto one another. By means of the method for performing ecological restoration on the steep rock slope through the soil fixing cage and the soil fixing cage provided by the invention, water and soil can be effectively maintained, falling off of a foreign soil layer is prevented, and rain water erosion resistance of the foreign soil layer is improved; and the problem of nutrient exchange necessary to plant growth can also be effectively solved, a platform and growth environment for stable growth of plants is provided, the implementation method is simple and easy to perform, the cycle is short, and the method can be well applied to the ecological restoration process of the steep rock slope.

Description

technical field [0001] The invention belongs to the technical field of slope ecological restoration, and in particular relates to a method for carrying out ecological restoration on steep rock slopes by using a soil-fixing cage. Background technique [0002] In the process of ecological restoration of slopes, some steep rocky slopes are often encountered. Such slopes themselves lack the soil environment such as water, heat, gas, and fertilizer necessary for plant growth, resulting in low vegetation coverage and poor soil and water conservation. poor effect. [0003] At present, the most commonly used vegetation restoration method applied to extremely steep rocky slopes is the bolt frame beam technology. But the grid area is large, the soil will gradually accumulate to the bottom, the water and soil conservation effect is poor, the guest soil layer is not resistant to rain erosion, it is easy to fall off, and the vegetation is easy to degrade; each independent grid is airtig...
