Description

The manufacturing method of vegetation mat for slope protection and the vegetation mat for slope protection manufactured by such a method

The present invention relates to a method of manufacturing a vegetation mat for slope protection and a vegetation mat for slope protection manufactured by such a method, and more particularly, it has excellent germination and growth effects of seeds, and for slope protection that effectively prevents soil leakage from the slope. It relates to a method for manufacturing a vegetation mat and a vegetation mat for slope protection manufactured by such a method.

In general, landslides or bank collapse may occur due to the rapid flow of running water on the slopes of rivers or roads. Various types of structures are constructed to protect the slope while preventing such accidents.

Among these structures, concrete placing method in which concrete modtar is directly placed on the surface, stone pasting method in which stones or concrete blocks are stacked and bonded with a binder such as mortar, concrete block method, and large natural stone or artificial stone are simply stacked. A stone-laying method and a gabion-tape method in which a net filled with stones is stacked along the slope are known.

Among these slope construction methods, the concrete pouring method can prevent large-scale catastrophes caused by sudden collapse of the revetment work because the corresponding concrete structure subsides when the ground subsides, so the subsidence can be visually and easily identified. There is a problem of destroying the environment and ecosystem, and the stone attaching method, concrete block method, and stony construction method are mostly constructed using relatively large stones, which require a lot of equipment and have a lot of difficulty in obtaining stone materials. have.

In recent years, lawns or trees are planted on slopes to prevent accidents. However, there is a problem in that it takes a long time for grass or tree planting to grow completely and to have a solid slope. In order to solve this problem, vegetation mats have been developed and used.

However, the conventional vegetation mat has a problem in that the planting materials such as grass cannot grow properly because the germination rate of seeds is low, and there is a high possibility that soil leakage occurs due to a rapid flow of running water when concentrated torrential rain occurs.

Therefore, an object of the present invention is to increase the seed germination rate of the vegetation mat, so that the planting materials such as grass can grow well, and the vegetation mat for slope protection that can prevent the outflow of soil even if the flow of running water is rapidly increased due to concentrated torrential rain. It is to provide a manufacturing method.

And, another object of the present invention is to provide a vegetation mat for slope protection manufactured by the novel method.

In order to achieve the above object, a method of manufacturing a vegetation mat for slope protection according to an aspect of the present invention includes the steps of (S1) applying a liquid fertilizer to a nonwoven fabric in which seeds are located on the surface or inside; (S2) drying the nonwoven fabric coated with liquid fertilizer in a dryer; And (S3) forming a soil loss prevention layer including a filling mat layer made of vegetable fibers and a core net layer made of a net shape on the upper surface of the dried nonwoven fabric.

In this case, in the step (S1), the weight per unit area of the nonwoven fabric may be 100 to 300 g/m ² .

In addition, the non-woven fabric may include vegetable fibers extracted from polyester, cotton, jute, or coconut, or a mixture thereof.

In addition, the application in step (S1) may be performed by spin coating, dip coating, spray coating, doctor blade, or roll coating method.

Meanwhile, the temperature for drying the nonwoven fabric in step (S2) may be 20 to 30°C, and the residence time of the nonwoven fabric in the dryer may be 3 to 5 minutes.

In addition, the soil loss prevention layer may be composed of a filling mat layer positioned on the upper surface of the nonwoven fabric and a core net layer positioned on the upper surface of the filling mat layer, or, a core positioned on the upper surface of the nonwoven fabric. It may be composed of a net layer, a filling mat layer positioned on an upper surface of the core net layer, and a core net layer positioned on an upper surface of the filling mat layer.

On the other hand, the vegetation mat for slope protection according to another aspect of the present invention, seeds are located on the surface or inside, non-woven fabric to which liquid fertilizer is applied; And a soil loss prevention layer located on the upper surface of the nonwoven fabric and including a filling mat layer made of vegetable fibers and a core net layer made of a net shape.

According to the present invention, after the construction of the vegetation mat, the liquid fertilizer, which was dried by bittern or rainwater, melts to aid in germination and growth of seeds, so that plants such as grass can grow well, and concentrate. Even if the flow of running water increases rapidly due to heavy rain, etc., it is possible to prevent the outflow of soil, so that slopes of rivers, roads, and railways can be protected.

Hereinafter, the present invention will be described in detail with reference to the drawings. The terms or words used in this specification and claims should not be construed as being limited to their usual or dictionary meanings, and the inventor may appropriately define the concept of terms in order to describe his own invention in the best way. It should be interpreted as a meaning and concept consistent with the technical idea of the present invention based on the principle that there is.

Therefore, since the configuration described in this specification is only the most preferred embodiment of the present invention and does not represent all the technical spirit of the present invention, there are various equivalents and modifications that can replace them at the time of the present application. It should be understood that you can.

A method of manufacturing a vegetation mat for slope protection according to an aspect of the present invention comprises the steps of (S1) applying a liquid fertilizer to a nonwoven fabric in which seeds are located on the surface or inside; (S2) drying the nonwoven fabric coated with liquid fertilizer in a dryer; And (S3) forming a soil loss prevention layer including a filling mat layer made of vegetable fibers and a core net layer made of a net shape on the upper surface of the dried nonwoven fabric.

Since the conventional vegetation mat has a low seed germination rate, there is a problem that the planting materials such as grass cannot grow properly, and there is a high possibility that soil leakage occurs due to a rapid flow of running water when a concentrated torrential rain occurs.

However, as in the present invention, if the vegetation mat to which the nonwoven fabric is applied after the liquid fertilizer is applied is applied on the slopes of rivers, roads, railroads, etc., liquid fertilizer that has been dried by water or rain after the vegetation mat construction It melts to help germination and growth of seeds, so that plantings such as grass can grow well, and even if the flow of running water increases rapidly due to torrential rain, etc., it is possible to prevent soil leakage. You can protect the slopes.

When explaining in more detail the manufacturing method of the vegetation mat for slope protection of the present invention, first, a liquid fertilizer is applied to a nonwoven fabric in which seeds are located on the surface or inside (step S1).

At this time, the seeds that can be used may be geumgye-guk, marguerite, sticky sprouts, etc. in spring, and in summer, gold pheasant's legs, mulberry sprouts, bee yellow, buddha flowers, wormwood scallop, giant pheasant's amaranth, dianthus, etc. May be reed, mountain country, gujeolcho, dogwood, moonroot grass, water silver grass, sukryeong, silver grass, etc., but are not limited thereto, and appropriate seeds may be selectively used depending on the flow rate of the river or the environment or aesthetics of the region.

In addition, the weight per unit area of the nonwoven fabric may be 100 to 300 g/m ² , and may be appropriately adjusted according to the slope of the slope and the flow rate of the river.

However, if the weight of the nonwoven fabric is less than 100 g per 1 m ² , it is not possible to adequately prevent the outflow of soil, and if it exceeds 300 g, the soil may be protected, but the nonwoven fabric is formed thick so that the seeds can take root properly. There may be problems that cannot be done.

In addition, the seeds may be located at 20 to 25 g per 1 m ² of the nonwoven fabric, and may be appropriately adjusted according to the slope of the slope and the flow rate of the river.

However, if the above seeds are present in an amount of less than 20 g per 1 m ^{2 of} nonwoven fabric, the density of the planting material grown from the seeds may be small, resulting in a problem that the slope may be lost due to soil leakage, and exist in excess of 25 g. In this case, there may be a problem in that the growth of the plantings is degraded and it is difficult to grow well.

Meanwhile, the non-woven fabric may include vegetable fibers extracted from polyester, cotton, jute, or coconut, or a mixture thereof. In particular, vegetable fibers extracted from jute or coconut are natural materials and may be decomposed in the ground after construction of a vegetation mat.

Meanwhile, in general, fertilizer refers to a substance that causes chemical changes in soil and a substance that affects plants in order to nourish plants or to help plant cultivation.These fertilizers are based on fertilization methods, It is classified into granular fertilizer, powder fertilizer, filament fertilizer, solid fertilizer, and liquid fertilizer according to the manufacturing method and properties, and classified into organic fertilizer, inorganic fertilizer and mineral fertilizer depending on the raw material, and sweet fertilizer, compound fertilizer, BB fertilizer, and It is classified into nitrogenous fertilizer, phosphate fertilizer, scalloped fertilizer, and trace urea fertilizer, and is classified into quick-acting fertilizer, slow-acting fertilizer, and sustained-acting fertilizer according to its effectiveness, and categorized into water fertilizer, horticultural fertilizer and fruit water fertilizer depending on the purpose, and fertilizer According to the process standard, it is classified into inorganic nitrogen fertilizer, inorganic phosphate fertilizer, inorganic scallop fertilizer, compound fertilizer, organic fertilizer, calcareous fertilizer, siliceous fertilizer, goto fertilizer, trace urea fertilizer, grated fertilizer, and grated fertilizer. It is classified into boiled bran, ash, manure residue, side soil, amino acid fermentation by-product fertilizer, dry chicken meal, dry livestock waste, boiled rice husk and sawdust, soil microbial agent and soil activator fertilizer.

Liquid fertilizers composed of liquids, which are obtained by diluting powdered or granular fertilizers, are also called liquid fertilizers, and are mainly classified as type 4 complex fertilizers. In general farming households, sesame cake, fish meal, etc. In addition, chemical fertilizers for liquid fertilizers are used that are easily soluble in water.

In general, liquid manure is composted in a liquid state by mixing manure excreted by livestock and feed or litter that is naturally generated in the process of rearing livestock. Compared with compost, it is used as a quick-acting and organic fertilizer like chemical fertilizer. It has the advantage of having a lasting effect.

In the present invention, the application of the liquid fertilizer may be performed by a spin coating, dip coating, spray coating, doctor blade, or roll coating method, but is not limited thereto.

Then, the nonwoven fabric to which the liquid fertilizer is applied is dried in a dryer (step S2).

Here, the temperature at which the nonwoven fabric is dried may be 20 to 30° C., but if it is less than the above temperature range, drying is not well performed and seeds may germinate during product storage due to residual moisture after production, which is not preferable. If it exceeds, there is a problem that the seeds contained in the nonwoven fabric are damaged, and the germination rate is lowered.

In addition, the residence time of the nonwoven fabric in the dryer may be 3 to 5 minutes, and if it is less than the above time range, the liquid fertilizer is not properly dried, so that seeds may be germinated during product storage after production. If the time range is exceeded, there is a problem that the germination rate is lowered by adversely affecting the seeds due to the disappearance of beneficial components of the fertilizer.

1 is a view schematically showing a process of drying after applying a liquid fertilizer to a nonwoven fabric according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating a liquid fertilizer applied to a nonwoven fabric according to another embodiment of the present invention, It is a view schematically showing the drying process, Figure 3 is a view schematically showing the interior of the dryer for drying the nonwoven fabric according to an embodiment of the present invention.

1 to 3, when the liquid fertilizer 2 is applied to the nonwoven fabric 1, the liquid fertilizer 2 may be applied by the silicone roller 3 and supplied through the quantitative supply motor 5 ) May be applied to the nonwoven fabric (1) by a volume control sprayer (6).

Subsequently, the nonwoven fabric 1 coated with the liquid fertilizer is put into the dryer 4 for drying, and in order to increase the drying efficiency, the nonwoven fabric 1 moves in a zigzag within the dryer 4 as shown in FIG. , It is possible to increase the residence time of the nonwoven fabric (1) in the dryer (4).

Finally, on the upper surface of the dried nonwoven fabric, a soil loss prevention layer including a filling mat layer made of vegetable fibers and a core net layer made of a net is formed (step S3).

In this case, the filling mat layer may be made of vegetable fibers such as rice straw, coconut fiber, hemp, and bamboo. The filling mat layer maintains the shape of the vegetation mat for slope protection. The filling mat layer maintains its shape and facilitates transportation before the vegetation mat for slope protection is installed on the slopes of rivers, roads, and railroads. In addition, the filling mat layer serves to prevent the outflow of seeds located on the surface or inside of the nonwoven fabric.

On the other hand, the filling mat layer may be formed of a biodegradable fiber material other than vegetable fibers. The filling mat layer may be an aliphatic polyester-based biodegradable fiber, an aliphatic/aromatic copolyester-based biodegradable fiber, or a biodegradable fiber in which the biodegradation rate is slower than that of the vegetable fiber.

In addition, the core net layer may be made of the same vegetable fiber or biodegradable fiber as the filling mat layer, and is formed in a net shape.

Since the core net layer is positioned on the filling mat layer, it can firmly support the lower layers and serve as a shock absorbing material. In addition, it is possible to prevent plants from being swept into the waterway for a certain period of time after seed germination until the roots are taken down in the soil, and if the river overflows and the river flows to the part corresponding to the slope, the flow rate of the river can be slowed down. I can.

Here, the soil loss prevention layer may be composed of a filling mat layer positioned on an upper surface of the nonwoven fabric and a core net layer positioned on an upper surface of the filling mat layer, and a core net layer positioned on the upper surface of the nonwoven fabric, It may be composed of a filling mat layer positioned on the upper surface of the core net layer and a core net layer positioned on the upper surface of the filling mat layer. When the core net layer is located on both sides of the filling mat layer, the filling mat layer can be more firmly fixed, and the nonwoven fabric can be better supported on the slopes.
