Problems solved by technology

Patent document CN1641110A discloses a straw paper honeycomb board sand-fixing barrier and its application in the prevention and control of wind and sand hazards. The straw paper honeycomb board is prepared and criss-crossed to form small honeycomb grids, which are then surrounded by small grids to form large grids to realize desertification. Controlling and preventing wind and sand hazards is a technical method of plug-in honeycomb construction, but the plug-in laying is time-consuming and the area of ​​plug-in laying is limited, which restricts the implementation of simple, fast and large-area laying repair technology

Embodiment 1

[0047] Example 1: Ecological Restoration of Degraded Environment of Black Soil Beach, Land Desertification, Grassland Degraded Soil, Slope Soil Erosion, etc.

[0048] Flatten and arrange the ground base layer to be repaired along the ground surface, stretch and lay flat-cut and drawn mesh honeycomb paper, multi-layer pasted honeycomb paper or wet-pressed honeycomb paper on the ground surface, and build a network between the mesh honeycomb paper layer and the ground base layer. Through the connection, a mesh base surface geotechnical layer is formed. The thickness of the reticulated base surface geotechnical layer formed by stretching and laying, lamination and lap fixing, such as flat-cutting and drawing honeycomb paper, multi-layer pasting honeycomb paper or wet-pressing honeycomb paper, is preferably 1cm to 5cm, that is, the honeycomb paper is stretched. The thickness of the honeycomb net shape is expanded, and the net honeycomb paper and the honeycomb paper are overlapped a...

Embodiment 2

[0056] Example 2: Ecological restoration of wound surface in engineering construction

[0057] Flatten the base layer of the wound surface of the engineering construction that needs to be repaired and rebuilt, stretch and lay flat-cut and drawn mesh honeycomb paper, multi-layer pasted honeycomb paper or wet-pressed honeycomb paper along the ground surface of the base layer to construct a mesh honeycomb paper layer and engineering construction The through connection between the base layers on the wound surface forms a reticulated base surface geotechnical layer. The thickness of the reticulated base surface geotechnical layer formed by stretching and laying, lamination and lap fixing, such as flat-cutting and drawing honeycomb paper, multi-layer pasting honeycomb paper or wet-pressing honeycomb paper, is preferably 2cm to 15cm, that is, the honeycomb paper is stretched. Expanded into the thickness of honeycomb mesh, the meshed honeycomb paper and the honeycomb paper overlap eac...

Embodiment 3

[0064] Example 3: Mine reclamation takes ecological restoration of wound surface in coal mining area as a list

[0065] First, rebuild the basal layer of the wound surface in the coal mining area, and use 77.2-86.4 parts of 2-6 cm large particle aggregate of coal gangue, 8.9-15.0 parts of cement, 2.2-3.8 parts of pulverized coal slag, and 2.3-4.7 parts of water. , 0.16~0.28 parts of water reducing agent. ①First, the large particle aggregate of coal gangue and water with a total water consumption of 20% to 40% are stirred for 20 to 30s; ②Add cement and pulverized coal slag, which account for 40% to 50% of the total consumption, and stir for 20 to 40s; ③Add more The water accounting for 20% to 40% of the total water consumption and the water reducing agent accounting for 50% of the total consumption are stirred for 20 to 40s; 140s. The uniformly stirred slurry is spread or sprayed onto the flattened wound surface of the coal mine area, and then the base layer of the wound surf...

Abstract

The invention discloses an ecological restoration material and application thereof. The ecological restoration material comprises a net-shaped base surface soil working layer, an ecological restoration plant growth layer and an upper surface covering net, wherein the net-shaped base surface soil working layer is formed by stretching and laying a net-shaped honeycomb paper layer on a to-be-repaired layer, and enabling the honeycomb paper layer and the to-be-repaired layer to be mutually solidified through an adhesive; the honeycomb paper layer is filled with a solid material required by plant growth to form an ecological restoration plant growth layer; honeycomb paper is stretched and laid on the ecological restoration plant growth layer to form an upper surface covering net, and the upper surface covering net and the ecological restoration plant growth layer are bonded through an adhesive. The ecological restoration material is suitable for ecological restoration of a black soil beach degraded environment, land desertification, grassland degraded soil, slope water and soil loss and an engineering construction wound surface in a cold region, desert greening or mine reclamation ecological reconstruction. According to the ecological restoration material, the restoration layer and the wound surface or the soil surface can form through connection, and rapid ecological restoration is achieved.

Description

technical field [0001] The invention relates to an ecological restoration material and its application, and belongs to the technical field of ecological restoration. Background technique [0002] In recent years, the increasing intensity of production and business activities of human society and the impact of climate change have caused varying degrees of damage to the ecological environment, especially in areas with harsh environmental conditions, low temperature and wind, sloping land, including plant and soil quality degradation, soil The layer is thin, soil fertility is poor, and soil erosion is serious, causing irreversible changes in its ecosystem structure and functional processes. There are also fragile ecological environment problems such as poor water and fertilizer retention capacity, serious soil erosion, loss of carrying potential of soil layers, etc. Aiming at the problems of land desertification, grassland soil degradation, water and soil loss, and the ecologi...
