1 is a flow chart illustrating a Masato slope slope erosion prevention recording method according to an embodiment of the present invention.

Referring to Figure 1, Masato slope slope erosion prevention greening method according to an embodiment of the present invention is a step of preparing an erosion prevention stabilizer has been proven erosion prevention performance (S100), water in the erosion prevention stabilizer has been proven anti-erosion performance , A mixing step of preparing seeding materials by mixing seeds and fertilizers (S110), and a spraying step of spraying the greening material including an erosion prevention stabilizer having proven erosion prevention performance on the Masato slope to form a vegetation base layer (S120). ).

First, by using a rainfall reproducing apparatus that can reproduce artificial rainfall prepares an erosion prevention stabilizer has been proven to prevent erosion on the Masato slope (S100).

Figure 2 is a flow chart illustrating the steps of preparing the anti-erosion stabilizer has been proven anti-erosion performance.

Referring to Figure 2, the preparation step (S100) is a step of filling the Masato slope of the Masato slope into the model experimental zone and uniformly compacting step (S101), the recording material comprising an anti-erosion stabilizer to verify the anti-erosion performance in the model experimental zone Spraying step (S102), mounting the model experimental sphere on the rainfall reproducing apparatus (S103), while reproducing artificial rainfall using the rainfall reproducing apparatus, by measuring the amount of recording material and Masato loss in the model experimental zone, to prevent erosion Verifying the erosion prevention performance of the erosion stabilizer to verify the performance (S104), and determining the mixing ratio of the erosion prevention stabilizer greening material using the rainfall reproducing apparatus (S105) It may include.

The model test sphere may be made of a container having an open top surface having a size of 0.6m × 1.0m × 0.1m in width, length, and depth. That is, the open top surface of the model experiment sphere may have an area of 0.6 m 2.

The model experimental zone can be filled with Masato, for example, the Masato at the site of the Masato slope through the open top surface, and the Masato filled in the Model Experimental Zone can be uniformly compacted until the soil hardness index is 10 mm.

The masatos filled in the model test area are sprayed with greening material containing anti-erosion stabilizers to verify their anti-erosion performance. Here, the greening material is different from the greening material in the mixing step (S110), and the same composition as the erosion stabilizer which tries to verify the erosion prevention performance instead of the erosion prevention stabilizer whose erosion prevention performance has been verified. Can be made. At this time, the greening material may be sprayed on the model experiment sphere using an air spray gun.

The rainfall reproducing apparatus is a device capable of reproducing artificial rainfall, and the rainfall intensity and time of the artificial rainfall can be controlled.

If artificial rainfall is reproduced while the model test section is mounted on the rainfall reproducing apparatus, the amount of greening material and Masato loss in the model test section can be measured by a collecting device installed at the bottom of the model test section. The erosion performance of the erosion stabilizer can be determined by comparing the amount of greening material and Masato loss with the reference value. In particular, the amount of greening material and masato loss in the case of using a synthetic adhesive (CMC, carboxymethyl cellulose) used as an anti-corrosion stabilizer in the conventional greening method can be determined by setting the reference value, but is not limited thereto.

Table 1 shows the results of measuring the amount of greening material and Masato loss by performing artificial rainfall test on the model test area sprayed with four different erosion stabilizers. At this time, the rainfall reproducing apparatus reproduced the artificial rainfall for 260 minutes at the rainfall intensity of 120 mm / hr, which is the 100-year maximum rainfall, and measured the amount of greening material and Masato loss.

Erosion Prevention Stabilizer First Model Experiment Zone 2nd Model Experiment Zone 3rd Model Experiment Zone 4th Model Experiment Zone Greening materials and Masato loss 823 g 94g 4,998 g 28,395 g

Referring to Table 1, a second model experiment using hydrophilic colloidal particles of plantain seed blood as an erosion stabilizer was compared with a third model experiment using a synthetic adhesive (CMC, carboxymethyl cellulose) as an erosion stabilizer. It can be seen that the amount of greening material and masato loss in the ward was significantly lower. Hydrophilic colloidal particles, such as plantain seed blood powder, can be gelled by reaction with water. In other words, the Masato slope is very dry, so it is easy to cause soil loss due to rainfall, but the hydrophilic colloidal particles absorb water to gel, thereby improving the adhesiveness of the Masato slope, thereby preventing the loss of soil on the Masato slope. In addition, it has excellent water retention and expansion ability to create a favorable environment for plant growth.

When the erosion stabilizer, which has been proved to be effective in preventing erosion, for example, an anti-erosion stabilizer including plantain seed blood, is selected, by performing artificial rainfall experiments while changing the mixing ratio of the erosion stabilizer in the greening material, the mixing step (S110) Optimal blending ratio can be determined. Increasing the compounding ratio of the erosion stabilizer improves the erosion prevention performance, but there is a problem that the construction unit cost increases, while lowering the compounding ratio of the erosion stabilizer can reduce the construction cost, but there is a problem that the erosion prevention performance is lowered. Therefore, it is important to determine the optimum blending ratio of the erosion stabilizer. In particular, in order to determine the mixing ratio of the erosion stabilizer, artificial rainfall experiments should be conducted in consideration of the soil characteristics and the slope of the Masato slope.

Next, water, seeds, and fertilizers are mixed with an erosion prevention stabilizer, which has been proven to prevent erosion, to prepare a greening material (S110).

The erosion stabilizer included in the greening material in the mixing step (S110) means an erosion prevention stabilizer whose erosion prevention performance has been verified through the rainfall reproducing apparatus as described above. That is, the erosion stabilizer may comprise hydrophilic colloidal particles, such as plantain seed blood.

Seeds can be prepared from woody plants, herbaceous plants, exotic plants or mixtures thereof.

Fertilizers include complex fertilizers. Compound fertilizer is a fast-acting chemical fertilizer that can stabilize the slope by inducing vegetation at the beginning of the greening process. However, compound fertilizers have a long-lasting effect, which can cause plants to die on dry, rough Masato slopes, especially when the slopes of Masato slopes are steep, for example, on the Masato slopes with 33 ° to 45 ° slopes. There may be a problem that is easily released. In order to solve this problem, it is possible to mix the home fat fertilizer with the compound fertilizer. The ripening organic substrate fertilizer is prepared by mixing organic materials such as bark, sawdust, pig meal and poultry, and minerals such as lime. Since the home fertilizer is excellent in fertility, it is possible to form a stable vegetation base on the Masato slope by supplementing the compound fertilizer which is a fast-acting fertilizer and exerting a long-term sustaining effect. In addition, the non-oil base fertilizer is excellent in breathability and drainage, it is possible to replace the paper coating fiber, which is a conventional coating agent by uniformly coating the Masato slope surface to an appropriate thickness. That is, the paper fiber is difficult to coat the Masato slope evenly because it adversely affects the growth of the plant when used excessively, but the non-oil base fertilizer can be uniformly coated to a proper thickness because it helps the plant growth. The low-temperature organic fertilizer may react with water and adhere to gelled hydrophilic colloid particles, thereby reducing the possibility of loss on the Masato slope. Similarly, home-based fertilizers can be used in combination with compound fertilizers to reduce the leaching of compound fertilizers.

On the other hand, the greening material may contain a coating agent, a pigment, etc. in addition to the erosion stabilizer, water, seeds, fertilizers.

Next, the vegetation base layer is formed on the Masato slope by spraying the greening material containing the anti-erosion stabilizer has been proven to prevent erosion performance (S120).

The greening material can be sprayed onto the Masato slope with an air spray gun.

That is, the first inclined plate 200 and the second inclined plate 300 may be formed on both sides with respect to the central axis of the first transfer channel 110, respectively.

The second inclined plate 300 is formed to be inclined with respect to the conveying direction of the greening material. In this case, the second inclined plate 300 is formed to be inclined opposite to the first inclined plate 200. That is, if the first inclined plate 200 is formed to be inclined at 30 ° with respect to the conveying direction of the greening material, the second inclined plate 200 may be formed to be inclined at 210 ° with respect to the conveying direction of the greening material. As a result, the operator uses the air spray gun 10 including the first inclined plate 200 and the second inclined plate 300 to separately operate the same effect as spraying the greening material while twisting the fire hose in the conventional greening method. Can be reproduced without. Therefore, the operator can evenly spread the greening material with increased adhesiveness due to the hydrophilic colloidal particles on the Masato slope even if the skill is low.

As a result, the compressed air supplied from the compressed air storage tank may be supplied to the first transport channel 110 via the second transport channel 410. Compressed air supplied through the second conveying channel 410 strikes the greening material passing through the first conveying channel 110, thereby crushing the greening material having increased adhesiveness due to hydrophilic colloidal particles.

The compressed air supply unit 400 may be a flow control valve 420 is formed.

The flow control valve 420 may adjust the amount of compressed air transferred through the second transfer channel 410. As a result, according to the adhesiveness of the greening material that can vary depending on the mixing ratio of the hydrophilic colloidal particles, by controlling the flow rate control valve 420 to adjust the amount of compressed air conveyed through the second transfer channel 410, compression The grinding efficiency of the greening material by air can be optimized.

The flow control valve 420 may be a ball valve.

Referring to FIG. 4, the first inclined plate 200 and the second inclined plate 300 may be formed to be spaced apart from each other with respect to the central axis of the first transport channel 110. As a result, the greening material may be inclinedly transported along the first inclined plate 200 or the second inclined plate 300, and may be advanced while rotating through the space between the first inclined plate 200 and the second inclined plate 300. In addition, some of the greening material conveyed along the central axis of the first conveying channel 110 is not interfered by the first inclined plate 200 and the second inclined plate 300 and the first inclined plate 200 and the second inclined plate 300. You can go straight through the space between). Accordingly, the greening material conveyed through the first conveying channel 110 may include a first rotational flow passing through the first inclined plate 200, a second rotational flow passing through the second inclined plate 300, and a first inclined plate 200. It can be divided into three streams of straight stream passing between the second inclined plate 300, whereby a highly viscous greening material can be evenly sprayed on the Masato slope. First and second rotational flows generated by the first and second inclined plates 200 and 300 are indicated by arrows in FIG. 3.
