In order to solve the above problems, the present invention comprises the steps of producing artificial green, green soil stabilizer by mixing a predetermined ratio of the recording material; Removing the rough stone, the boulder, etc. of the inclined surface by cutting, blasting, etc. and arranging the inclined surface to have a certain degree of curvature by using equipment such as a fork lane; Forming a drainage layer on the arranged slope and forming a drainage path on the drainage layer; Installing and fixing an attachment network on an inclined surface on which the drainage channel is completed by using an anchor pin; and mixing 80% of the greening material with water and spraying the compressed material at a high speed to the first mounting on the sloped surface; It is a problem solving means to be solved by the present invention to provide a sloped greening method consisting of mixing the seed and water in the remaining 20% of the greening material and the secondary mounting on the primary mounting slope.

The present invention is to install the greening material mixed with greening soil stabilizer mixed with water purification plant sludge cake, cement, calcium sulfate, Busan lime, zeolite, superabsorbent polymer, so that the soil particles are made granular, water holding properties, bobbing power, adhesion, etc. As it affects the improvement, it is easy to mount slopes by high pressure installation of greening materials, and the greening soil stabilizer contains a large amount of inorganic substances that are effective in the growth of food fire, and the greening soil stabilizer forms a large amount of soil voids By supplying oxygen and improving the boring power, the germination rate of seeds can be improved after installation of greening materials.Because greening soil stabilizer containing water purification plant sludge cake and Busan lime is used, it can reduce the cost of greening on slopes by recycling resources. It can be effective.

The present invention provides a sloped greening method comprising the steps of: manufacturing a greening material by mixing artificial soil, greening soil stabilizer in a predetermined ratio; Removing the rough stone, the boulder, etc. of the inclined surface by cutting, blasting, etc. and arranging the inclined surface to have a certain degree of curvature by using equipment such as a fork lane; Forming a drainage layer on the groomed slope and forming a drainage path on the drainage layer; Installing and fixing an attachment network using an anchor pin and landing pin on the slope on which the drainage channel is formed; Mixing 80% of the greening material with water and spraying the same on the inclined surface first by compressing and spraying at high speed;

Mixing the seed and water to the remaining 20% of the greening material and secondary mounting on the primary mounting slope.

And, the greening material is mixed with artificial soil 90 ~ 95 kg soil stabilizer 5 ~ 10 kg.

Soil stabilizers included in the greening material consists of water purification sludge cake 20 ~ 39 kg cement 13 ~ 17 kg calcium sulfate 25 ~ 35 kg Busan lime 10 ~ 20 kg zeolite 8 ~ 12 kg super absorbent polymer 5 ~ 10 kg.

The superabsorbent polymer uses sodium acrylate-acrylate copolymer.

The present invention sloped greening method of this configuration, first, the artificial soil is mixed with 90 ~ 95 kg soil stabilizer 5 ~ 10 kg of artificial soil to produce a greening material.

When the greening materials are manufactured, the slopes of the greening targets are covered and compacted, and in the case of earth and sand grounds, they are swept away from the ground surface by weathering erosion using equipment such as fork-lane, or they are shallowly embedded with soils deposited on small ends. Remove the stones etc.

On the slope, the lower part is finished in a natural form avoiding acute angles in order to harmonize with the surrounding natural landscape, and to prevent freezing and erosion. However, when there is a good existing vegetation, it may not be reviewed and selected.

In the case of rocky irregular rock slopes, cutting, blasting, etc. are performed to remove coarse and loose stones.

When covering and compacting the slopes, work should be carried out to have a certain degree of curvature so that the construction surface is not arranged smoothly to enable partial recording in harmony with the surrounding natural environment.

When the cover and compaction work of the slope is completed, the drainage work is carried out, and the drainage hole is first formed with a drainage layer separated from the covered and compacted slope.

And the drainage is formed in the drainage bar, the small end of the slope is provided with a cross-gradient or forming a drainage so that the greening material to be mounted is not eroded,

The slopes of the wetland are always absorbed and saturated with the greening material to be mounted, so there are fears of pests, and plant growth is difficult.

After the formation of drainage layer and drainage port is completed, the installation network is installed on the slope to facilitate the installation of the greening material. The attachment network is installed on the slope, and the wire is fixed on the upper side. Fix it.

In this way, when the foundation work is completed, the green material is mounted.

First, the prepared recording material is introduced into the mixing tank of the attaching machine. At this time, only 80% of the recording material is added to the mixing vessel of the attaching machine, water is mixed therein, and the primary mounting unit has a predetermined thickness by spraying at high speed through a spray nozzle. do.

Then, the remaining 20% of the greening material is added to the mixing tank of the attaching machine, water and seeds are mixed therein, and then compressed and sprayed at high speed through a spray nozzle, and the second mounting is carried out on the primary greening surface.

Here, when the slopes are dry or if foreign matter is attached, spray water first before attaching them, and when installing on rock slopes, avoid full-covered greening and perform natural partial greening due to cracks and irregularities. The protrusions and vertical and inverted slopes of the arm avoid the greening and concentrate the dents.

In this way, when the greening material is mounted on the slope, the thickness thereof is preferably 10 cm or more, and the thicker the gap between the arms, the thicker the mounting thickness.

This step records the slope.

This sloped greening method of the present invention is effective in recording a damaged sloped surface because the greening material is mixed with a green soil stabilizer mixed with a water purification plant sludge cake, cement, calcium sulfate, lime, zeolite, super absorbent polymer.

In other words, the advantages of each component contained in the greening soil stabilizer are combined to improve the germination rate of seeds, and the characteristics of each component are as follows.

Water purification plant sludge cake is sticky and dense with the addition of aluminum sulfate coagulant during water treatment. It contains a large amount of inorganic substances that are effective for plant growth, and is dissolved in water when mixing the above components. As it becomes an electrolyte, it is dispersed in a colloidal phase, and aluminum ions become a polymer and play a role of increasing adhesion of soil particles.

Cement transfers incomplete calcium hydroxide to a stable silica compound by hydration with water, thereby increasing the strength and chemical resistance of the ground.

Calcium sulfate maintains the state of colloidal dispersion in water, which activates the cement and pozzolanic reactions to affect the fluidity, and delays the setting time to maintain proper strength for a long time.

Busan lime plays a role in neutralizing alkaline acidified soils, thus affecting the improvement of soil properties.

The zeolite serves to increase the strength when the composition is hydrated and granulated.

The superabsorbent polymer uses sodium acrylate-acrylate copolymer, which has a large absorption capacity of several hundred times to several thousand times its own weight and does not release water even when pressure is applied from outside. It has the characteristics.

It also has a large number of hydrophilic groups, which adsorb ammonia to improve its binding capacity, and absorb solvent to form a swollen gel, which expands the pores between the soil and improves breathability.

Thus, the combination of the advantages of each component contains a large amount of inorganic substances that are effective for plant growth, and as a result of the granulation, it affects the physical properties of the soil, such as water holding capacity, binding strength, and adhesiveness. Make it possible.

In addition, by forming a large amount of soil voids by greening soil stabilizer to supply oxygen to the soil and improve the binding power, the germination rate of the seed after the greening material can be improved.

In addition, the use of greening soil stabilizer containing the water purification plant sludge cake and Busan lime, it is possible to reduce the cost of greening the slopes by recycling resources.
