Description

Slope greening composition, slope greening method using the composition, and slope greening system The present invention relates to a composition for slope greening, a slope greening method using the composition, and a slope greening system. More specifically, the invention relates to a composition for slope greening, a slope greening method using the composition, and a slope greening system that can delay dehydration as much as possible and improve moisture retention and nutrient retention capabilities compared to conventional methods, thereby maximizing seed germination rates and enabling early germination, which can contribute to achieving rapid ecological restoration. Slopes (also referred to as inclines, slopes, or embankments) constructed in conjunction with land development, road, and railway projects typically cover a large area; therefore, if left as they are, they are aesthetically unpleasing. Furthermore, because they are susceptible to collapse due to natural disasters, they can cause not only the loss of valuable lives but also damage to homes, thereby creating instability in industry and the daily lives of the people. Therefore, slope protection methods are required to safeguard slopes that have been left neglected. Slope protection encompasses proper design and construction, as well as continuous maintenance. In particular, the importance of slope protection has been steadily increasing in recent years due to recurring natural disasters and the resulting slope collapses. Slope protection methods are divided into methods that protect the slope by constructing separate structures on the slope and methods based on vegetation. The former construction methods include various techniques such as stacking or attaching stones or concrete blocks to the slope, installing grid blocks and filling them with stones or gravel, anchoring to a solid core using anchors, and inserting steel rods into the slope and pouring concrete over them. Meanwhile, these methods primarily involve preparing separate structures and constructing them on the slope; while they offer the advantage of preventing slope collapse, they are somewhat unfriendly as they do not blend well with the surrounding forest, and they also have the disadvantage of incurring massive construction costs. Therefore, in recent years, there has been a trend to mainly use the latter method, namely the vegetation method. Vegetation methods include the sodding method, in which sod (grass) is planted directly on the slope; the vegetation mat method, in which a mat with seeds and fertilizer attached is covered on the slope; the wet topsoil method, in which artificial soil made from organic waste is sprayed onto the slope to green the slope; the natural topsoil restoration method; and the spraying method, in which a mixture of seeds, fertilizer, soil, and water is sprayed onto the slope. The sodding method is effective for greening slopes because grass is planted directly on the surface, but it has the disadvantage of requiring a large workforce, which increases construction costs and prolongs the construction period. These disadvantages are equally present in the vegetation mat method. In contrast, while the wet topsoil removal method can reduce construction costs, it has the disadvantage of requiring a large amount of labor and potentially causing environmental pollution due to the use of waste materials. Additionally, although the natural topsoil restoration method is somewhat eco-friendly, it is expensive and poses a burden when applied to steep slopes without heat. Therefore, among construction methods using vegetation, the spraying method is commonly used. In the case of the spraying method, a mixture of seeds, fertilizer, soil, and water is sprayed onto the slope using a so-called applicator (also called a compressor), and it has the advantage of being easily constructed with minimal manpower, which can reduce construction costs and shorten the construction period. However, among conventional vegetation-based methods, particularly in the case of the spraying method, there is a problem that it is harmful to the environment because chemical adhesives (such as terracontent) are added in addition to the aforementioned mixture to achieve coagulation, moisture retention, and adhesion of organic soil. In addition, there is a disadvantage in that it is somewhat insufficient to create an environment suitable for plant growth, as it is difficult to maintain the soil's adsorption and moisture retention due to various causes such as the solidification of chemical adhesives or changes in physical properties, and the soil environment is not substantially improved due to poor sustainability of organic matter or soil aeration. Accordingly, although various methods have been proposed to address these drawbacks, the need for technological development to compensate for this arises, as the limitations of the materials constituting the composition cause moisture absorbed i
