Here, background arts related to the present disclosure are provided, and these do not necessarily mean known technologies.

Waste refers to substances that are not required for human life or industrial activities such as waste, combustion agents, sludge, waste oil, waste acids, waste alkali, and animal carcasses. It is said that the waste that occurs with the activity is waste at the workplace. Business wastes can be classified as designated wastes, which are harmful substances that can contaminate the surrounding environment, such as waste oil and waste acids, or can harm the human body, such as medical wastes, and general wastes at business sites.

The direction of disposal of household wastes and general wastes in business places has a great interest in various fields such as academia. However, it is true that long-term management measures and treatment measures are unclear in light of the development trend, and have been very passive in agricultural use and soil improvement. It is necessary to review the general waste treatment policies for domestic wastes and business sites so far, and to establish a mid- to long-term economic policy direction for economical and efficient waste treatment.

Sludge from domestic waste contains a large amount of nitrogen, phosphoric acid, and caries as well as microbial elements necessary for plant growth, which can be a useful resource for improving the physicochemical properties of soil and improving soil fertility. On the other hand, on the other hand, there are many harmful heavy metals that exceed the soil pollution standard, so it is difficult to recycle due to the poor quality of the soil environment due to soil pollution and the problem of food stability.

Until now, industrial waste classified as household waste and general waste was not easy to process because of its high organic content and high water content of 80 to 90%. So far, it has been treated as a method of stabilizing, dewatering and landfilling after narrow air treatment, and this method has been devised as a method of removing and incinerating moisture as it becomes difficult to treat due to the increase in the amount of general waste.

Currently, as a treatment method for recycling business wastes classified as household wastes and general wastes, it is used for soil amendments and landfills in road cutting sites and soil vegetation restoration sites using earthworm breeding, but these recycling methods are irregular and small, so supply and demand There are many difficulties in processing efficiency.

Therefore, in recent years, many studies have been conducted in terms of medium and long-term recycling of waste, and as one of the results of these studies, many studies have been conducted on composting using organic materials abundant in business waste classified as household waste and general waste.

On the other hand, in general, it is impossible to recover to natural vegetation due to the transition in a short period of time because most of the cutting and embankment slopes that occur at the construction site where large-scale civil works or complexes are constructed are mostly rock or barren soil. In particular, the natural scenery is damaged due to the collapse or breakdown of slopes due to rain in summer or cold in winter. For this reason, artificial greening is essential, and as a method of construction, there are many technologies by artificial soil and technology using various materials.

Accordingly, the present invention is to provide a vegetation restoration soil composition suitable for soil and plant growth using a waste sludge containing household wastes and general wastes at a business site and a sloped greening method using the same.

Preferably, a polyurethane-based resin is used.

The sloped greening method according to the present invention is a method of mixing the seed and water with the prepared vegetation restoration soil composition to make the slurry in a slurry form so that it can be easily attached to the slope, and attaching it to the sloped surface. Since there is no gap between them, the sense of unity is formed, so that the composition flows less in summer rains or cold winters, cracks do not occur well, and hardness and porosity of plants are easy to germinate and grow.

In the case of slurrying, it is preferable to add 20 to 50 wt% of water to the total composition to slurry in a semi-flow state. However, since the moisture content of the vegetation restoration soil is not constant, the water content ratio is not limited to this, and the vegetation restoration soil is slurried to a viscosity with excellent adhesion.

By spraying the vegetation restoration soil composition slurry according to the present invention once, it is possible to attach from a minimum of 0.5 cm to a maximum of 12 cm. It is characterized in that the slope is installed at a thickness of 0.5 to 2 cm in the case of soil, it is mounted at a thickness of 2 to 7 cm in the case of ripping arm, and 5 to 10 cm in the case of soft rock, and 7 to 12 cm in the case of hard rock.

In addition, when the thickness is more than 5 cm, the amount of seed (seed) is formed by first attaching the vegetation restoration soil composition slurry that does not contain seeds to form a foundation, and secondly attaching the remaining thickness with the vegetation restoration soil composition slurry containing seeds. As well as reducing the thickness of the seed layer can promote the germination of seeds.

Table 1 shows the mounting thickness and the mesh installation according to the type and slope of the slope. For example, when the slope of the embankment or cut is 40 ㅀ or less, it is possible to install it at 0.5 to 2cm without installing the fiber net. When the slope is 40 ㅀ to 50 ㅀ, it is better to install the fiber mesh to install 1 to 2cm. . In the case of the ripping arm, if the inclination is 30 ㅀ to 45 ㅀ, it is better to install the fiber mesh and install it at 2 to 5cm. For 45 ㅀ to 55 ㅀ, it is good to install the metal ridge net and install it at 5 to 7cm. In the rocky areas with a slope of 45 ㅀ or more, after installing a metal ridge net, it is first mounted as a slurry of vegetation restoration soil that does not contain seeds to prevent breakage of the slope and ensure vegetation base material to be attached smoothly.

The present invention not only improves the landscape and ecological functions of the slopes where it is difficult to improve vegetation due to construction work, but also induces germination and growth to induce vegetation and growth so that the slope of the slope and the damaged incision can be transformed similarly to the appearance before being damaged. It has the effect of making excellent greening quality by stably inducing and providing a soil environment suitable for growth by strengthening the bearing capacity of the slope.
