similoam soil substrate spraying technology


Technical concept - restoring nature in a natural way

Apply similoam substrate spraying techniques to create an ideal soil structure.

Selecting the most suitable plant species to ensure the proportion of trees and shrubs in the plant community in the later stage to achieve the restoration of nature.

Ensure the advanced construction technology to sublimate "repair" to "restoration" and make the potential disaster site a "scenic area".


Technology Overview

The core of similoam substrate spraying technology is the use of engineering and botany to quickly simulate a high-performance loamy substrate structure suitable for plant growth in nature through bionic technology.

Loamy soils are soils with a moderate content of clay, powder and sand in the composition of soil particles. The texture is between clay and sand, and has the advantages of both clay and sand, with good aeration and permeability, water retention and heat preservation properties, and particle size between 0.2mm and 0.02mm.

The structure is stable and has abundant humus, minerals, air, water, organic matter, etc. These substances exist in the form of solid, gaseous, and liquid in the soil matrix, which are interlinked and mutually constrained to provide the necessary growth conditions for plants, giving the most favorable standing conditions for plant growth on high and steep slopes, and both biological protection.


The soil structure simulated by similoam substrate spraying technology has two main layers, one is the humus layer (fully weathered layer), which has the characteristics of loamy soil structure, rich in humus, minerals, air, water, organic matter, etc., suitable for plant growth. Second, the leaching layer (strong weathering layer), the subgrade formed by similoam substrate spraying technology can be seen as a flexible reinforced anchoring material, which can improve the cohesion and internal friction angle of the soil and improve the mechanical properties of the original soil. It forms a high strength resistance to scouring and enables the substrate to adhere better to the bedrock of the mine slope. It can significantly improve the overwintering rate and rejuvenation rate of plants in arid and semi-arid regions.

The soil matrix formed by similoam substrate spraying technology contains a large amount of organic matter and minerals, which can provide plants with necessary nutrients, promote the activities of soil microorganisms, regulate soil acid-base reactions, and accelerate the growth of plant roots and above-ground parts.


The soil matrix formed by similoam soil matrix spraying technology has rich capillary pores (0.001-0.1 mm diameter soil pores), which can enhance the water absorption and water retention capacity of the soil. The increase in water content increases the soil soil water potential and facilitates water absorption by plants. Good water holding capacity is beneficial to improve germination rate and faster community formation.

similoam soil substrate has looseness and aeration suitable for plant growth, which can improve soil aeration and help plant seed germination, root development, microbial activity and nutrient conversion, and promote plant growth and development.

Geological hazards removal


Slope stability analysis

     Classify the type of rock structure of slope and judge the form of slope damage according to the type. Analyze the force conditions of the rock body, such as the self-weight of the rock body, blasting force, engineering force, groundwater action, etc., and calculate the shear strength using the limit balance analysis and deformation analysis method to analyze the stability of the slope. Judging the change trend of slope stability from geological causes, and proposing reinforcement measures to ensure slope stability.

  Slope stability protection technology

According to the current situation of slopes in the treatment area and the conditions of stratum production and lithology, slope reduction techniques are used to reduce the height and slope gradient of slopes. As needed, direct reinforcement techniques such as fill compaction, retaining walls and slope protection, lattice beams, anti-slip piles, concrete anti-slip plugs on sliding surfaces, anchor rods, prestressed anchor cables and flexible protection nets are adopted for slope stability protection.

Plant diversity selection and cultivation technology

In the selection of plants, we should pay attention to the function, role, size, adaptability, periodicity, control and continuity of plants, and also consider external factors such as climate, geographical environment and geological conditions. Comprehensive determination of plant types, planting methods, ways, collocation, and subsidiary parameters (such as the ratio of water pipes).

According to the local mountain geology, meteorology and other information, carry out forest survey in the region, fully consider the diversity of substrate configuration species, as well as the plant phreatic community, etc., and determine the plant species suitable for mine regreening, giving priority to local species, so that the slope is stable, overall regreening, soil and water conservation, and restoration of the original mountain appearance.   



similoam soil substrate ratio

Using plant ecological communities, such as fallen leaves, dead grasses and other humus as a source of soil nutrients, the natural minerals and organic compounds and trace elements are fully combined, combining multi-functional functions such as urease inhibition, nitrification inhibition, ammonia stabilization and plant growth regulation, and promoting plant growth with the extension of time.



Application of geomorphological classification

Geomorphic grading replicates nature and stabilizes the irregular shape of slopes. Trees and large shrubs tend to require more water, which enhances the stability of shallow slopes more than herbaceous vegetation. Therefore, trees should be clustered where runoff collects. Trees and large shrubs should also be highly concentrated along each depressional drainage flow line. Conversely, convex areas should be planted with more drought-tolerant herbaceous plants.
