The present invention relates to a vegetation base material, and more particularly, a light vegetation base material made from waste wood and waste paper, the vegetation mat provided with the vegetation base material, and easy to construct, replace and repair, and It relates to a manufacturing method.

Due to overheating urbanization, green space in cities is gradually decreasing. In order to secure the city's scarce green space, gardening in the city has begun, and ecological parks and tree plantings have recently been activated. However, it is difficult to secure green space in the city due to many buildings and residential facilities. As an alternative, there is a growing interest in greening methods using roofs of existing buildings. Roof greening of buildings has been adopted in many buildings recently because of the advantages of space recycling, simultaneous ecosystem construction, atmospheric purification, mitigation of urban heat island phenomena, environmental improvement through energy saving and microclimate control of buildings.

1 is a cross-sectional view showing a conventional vegetation structure for artificial ground greening 10. The vegetation structure 10 generally includes a growing soil layer 11, a filter layer 12, a drainage layer 13, a weatherproof layer 14, and a waterproof layer 15, on an artificial ground 20 such as a roof of a building. Is installed.

The growing soil layer 11 is a base material on which plants continuously grow, and has a disadvantage in that the load is large because it occupies most of the weight of the vegetation mat 10. The filter layer 12 has a fine soil of the growing soil layer during rainfall. Prevent flushing. Meanwhile, the drainage layer 13 is responsible for drainage from the growing soil layer 11, and the rooting layer 15 protects the waterproofing layer 15 and the building 20 from the roots of the plant, and the waterproofing layer 14 has a vegetation structure ( 10) serves to block the leakage of water to the building 20, as described above, the conventional vegetation structure 10 is not only complicated in structure, but also has the disadvantage that the overall weight is large by the load of the growing soil layer (11). there was.

On the other hand, in order to create a variety of vegetation through the vegetation structure 10, the growing soil layer 11 should have a sufficient depth. However, the deeper the soil, the greater the load on the building, the depth of the soil is limited for the structural safety of the building, and eventually the vegetation that can be created is also limited. Therefore, the conventional vegetation structure 10 not only applies a large load to the building but also has a problem that the deep vegetation structure 10 is not applied to the building having a weak structure. In addition, in order to establish the vegetation structure 10 on the roof 20 of the building, etc., as shown in Figure 1 it is necessary to construct several layers necessary for vegetation, the conventional vegetation structure 10 is not only inconvenient to construct, There is a problem that the partial replacement and repair is not easy. In addition, since the growing soil layer 11 that is the basis of vegetation includes soil or artificial soil, there is a problem that the vegetation structure 10 should be established only on a flat artificial ground.

The present invention has been made to solve the above problems, the first technical problem of the present invention is to provide a lightweight vegetation base material because the structure is simple, and the soil layer is not included at all.

The second technical problem of the present invention is to provide a vegetation mat having the vegetation base material, and easy to construct and maintain.

The third technical problem of the present invention is to provide a method of manufacturing a vegetation mat, which is lightweight and easy to construct.

The present invention to achieve the first technical problem,

The present invention provides a vegetation base material including a plurality of dense wood chips and a filler filled in a space between the wood chips to hold a plurality of dense wood chips in a plate shape.

According to one embodiment of the present invention, the wood chips are preferably wood chips obtained by crushing waste wood.

In addition, the filler preferably contains a waste paper pulp.

The filler may also contain a colorant, powdered activated carbon, a wet paper strength enhancer for papermaking or a paper surface sizing agent.

According to a preferred embodiment of the present invention, the vegetation base material may further include a reinforcement made of coconut fiber.

The present invention provides a vegetation layer made of the vegetation base material, in order to achieve the second technical problem; A planting layer further comprising a coating layer formed on the vegetation layer to fix the seed and the seed sown on top of the vegetation layer; And a drainage layer disposed below the vegetation layer, the drainage layer including a nonwoven sheet and a drainage plate disposed below the nonwoven sheet and having drainage grooves.

According to an embodiment of the present invention, the coating layer may include starch oxide.

The present invention to achieve the third technical problem,

(a) preparing wood chips, (b) preparing paper pulp slurries, (c) mixing wood chips and paper pulp slurries, and (d) forming molds and molds having drainage holes. Providing a vegetation base material manufacturing apparatus having a matching press plate, (e) injecting a mixture of the wood chips and the paper pulp slurry into a mold, and (f) pressing the mixture injected into the mold into the mold. It provides a method of manufacturing a vegetation mat comprising the step of molding the vegetation base material.

According to an embodiment of the present invention, the step (c) is preferably made by mixing 40 to 60% by weight of wood chips and 60 to 40% by weight of paper pulp slurry relative to the total weight of wood chips and paper pulp slurry. Here, the wood chip and paper pulp slurry may be further added with a pigment, powdery activated carbon, a paper wet strength enhancer or a paper surface size agent.

According to another embodiment of the present invention, reinforcement made of coconut fiber may be further added when the mixture is added in step (e).

According to another embodiment of the present invention, the forming mold of step (d) has one side having a first uneven shape and the other side having a second uneven shape opposite to one side and matching the first uneven shape. It is preferable.

In addition, after the step (f), further comprising the step of planting the seed on top of the vegetation layer consisting of the vegetation base material, wherein the seed planting step, the seed sowing on one side of the vegetation layer and , It is preferable to include a step of coating one surface of the vegetation layer seeded with an aqueous starch oxide.

In addition, after the step (f), it is preferable to further include the step of immersing the vegetation base material in a liquid fertilizer and then drying.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

Since the vegetation mat according to the present invention does not include any growing soil layer, the load is light, and it is not necessary to provide a separate filter layer and a waterproof layer, so that the structure is simple, and the seed, vegetation layer, and planting layer on the vegetation mat itself. And since the drainage layer is provided integrally, there is a feature that the construction is easy.

2 is a perspective view showing a vegetation base material according to the present invention. Vegetation base material 100 is a filler that maintains a plurality of wood chips 110, densely packed in a plate-like form, and a plurality of wood chips 110 packed in a space or voids between the wood chips 110 in a plate shape ( 120).

Vegetation base material 100 has a plate-like shape as a whole, the thickness of the vegetation base material 100 may be selected according to the type of vegetation so as to secure the depth required for the vegetation to be formed. In FIG. 2, the planar shape of the vegetation base 100 is shown to be rectangular, but the planar shape of the vegetation base 100 is not limited thereto, and may be a circle, a triangle, or an arbitrary polygon.

The wood chip 110 is wood chips obtained by crushing any wood. Preferably, the wood chips 110 are obtained by crushing wood waste or building waste wood that has been thinned out in the forest into a predetermined size (for example, 1.5 to 2 cm). Since the wood chip 110 is porous in nature of the material, various nutrients necessary for the growth of plants planted in the vegetation base material 100 may be retained in the wood chip 110. The content of the wood chip 110 in the vegetation base 100 is preferably 40 to 60% by weight relative to the total weight of the wood chips and paper pulp slurry, when less than 40% by weight of the nutrients required for plant growth It is not preferable because the ability to retain is low, and when the content exceeds 60% by weight, since the content of the filler 120 is relatively low, the strength of the vegetation base 100 may be reduced.

The filler 120 fixes the wood chips 110 so that the dense wood chips 110 form a plate shape. Filler 120 is made of a material that can take root of vegetation. Therefore, the filler 120 is made of a material that can penetrate the roots of the plant and may contain appropriate moisture and maintain the wood chip 110 to maintain the plate shape of the vegetation base material 100.

Filler 120 of the vegetation base 100 according to the present invention is preferably made of paper pulp. When the water is dehydrated in the mixture of the paper pulp slurry and the wood chip 110, the paper pulp is fixed and the fibers are bound to each other, each wood chip 110 is caught to the dense wood chip 110 of It may be formed of a filler 120 that can maintain the plate shape. The filler 120 of the paper pulp may be formed from paper pulp slurry formed by dissociating waste paper, for example, paper waste paper by adding water.

Since the filler 120 is made of paper pulp, the filler 120 has a high water absorption rate. Therefore, the plants planted in the vegetation base material 100 can be properly supplied with the moisture required for growth from the filler 120.

Filler 120 may contain a functional additive for improving the durability of the vegetation base material 100 and to give a favorable effect on the growth of plants. Examples of functional additives include powdered or granular activated carbon, corrosion inhibitors, vegetative harmless colorants to increase the wetting strength of paper pulp, and suppress the decay of vegetation base material and improve the soil, and act as a binder. Paper wetting strength enhancers for making paper, surface sizing agent for making the appropriate moisture is retained in wood chips and fillers. Such a functional additive is contained in the filler 120 by being added to the slurry of paper pulp. However, the paper surface sizing agent among the functional additives may be added to the slurry of paper pulp or applied to the surface of the vegetation base 100.

Meanwhile, the vegetation base material according to the present invention may further include a reinforcement made of coconut fiber, and the reinforcement made of coconut fiber is commonly used in the art, and not only increases wet durability, but also has a thickness of the vegetation base material. In case of thickening, it serves to increase durability. That is, when the vegetation requires deep soil, the thickness of the vegetation base material becomes thick. In this case, since the vegetation base material requires more durability to withstand the vegetation load, it is necessary to reinforce the durability. will be. The reinforcing material made of coconut fiber may be used by mixing the filler 120 after cutting the coconut fiber, but it is more preferable to use a net made of coconut fiber in terms of durability. The thickness of the net made of coconut fiber is not particularly limited, and may be appropriately adjusted in consideration of the thickness of the vegetation base material, and the number of the nets used is not particularly limited, and may be several layers spaced apart from the inside of the vegetation base material. This can be stacked.

3 is a perspective view of a vegetation mat according to the present invention.

Vegetation mat 200 according to the present invention includes a vegetation layer 210 made of the vegetation base material 100 described with reference to FIG. Vegetation layer 210 is composed of a plurality of wood chips 211 dense in the form of a plate, and a plurality of wood chips 211 filled in the space or voids between the wood chips 211 in the form of a plate and made of paper pulp The charging body 212 is provided. Vegetation layer 210 is made of a wide plate-like vegetation base material 100, it may be made of a rectangle or square of a length of several meters or tens of centimeters, the shape is not limited. The wood chip 211 and the filler 212 are the same as the vegetation base material 100, a description thereof will be omitted.

The vegetation mat 200 further includes a planting layer 220 formed on the vegetation layer 210. The planting layer 220 includes a seed 221 sown on the vegetation layer 210 and a coating layer 222 fixing the seed 221 on the vegetation layer 210.

Seed 221 may be sown on the vegetation layer 210 at appropriate intervals. The seed 221 to be sown may be selected in consideration of the depth according to the depth of the vegetation layer 210, on the contrary, after selecting a specific seed 221 may be determined the depth of the vegetation layer 210.

The coating layer 222 includes starch oxide. For example, the coating layer 222 may be formed by coating a solution in which starch oxide is dissolved on the vegetation layer 210 seeded with seeds 221. Oxidized starch constituting the coating layer 220 is used as a nutrient when the seeded seed 221 is initially germinated, while strengthening the fixing force of the seed 221, and also serves as a protective layer of the seed. The coating layer 222 may be formed over the entire surface on the vegetation layer 210 as shown, and may be formed so as to cover only the seeded seed 221.

In the vegetation mat 200 according to the present invention, the planting layer 220 including the seed 221 is formed on the vegetation mat 200, and the vegetation layer 210 provides the foundation and moisture necessary for the vegetation of the seed 221. As it is supplied, the vegetation mat 200 is itself equipped with all the elements necessary for vegetation of the seed 221.

Vegetation mat 220 according to the present invention further includes a drainage layer 230 disposed below the vegetation layer 210 to be constructed for artificial ground greening. The drainage layer 230 may include a drainage plate 231 having a drainage path (not shown) and a nonwoven fabric sheet 232 disposed on the drainage plate 231.

The drain plate 231 may be made of a synthetic resin such as polystyrene, and a plurality of drain grooves may be formed vertically and horizontally on a surface thereof, or a drainage path may be formed such that a conical protrusion is formed to drain the surroundings. On the other hand, the non-woven fabric sheet 232 is placed directly below the vegetation layer 210, and acts as a root barrier layer so that the roots of the growing seed 221 do not grow through the drain plate 231. The nonwoven sheet 232 may be provided attached directly to the drain plate 231. In this case, the drainage layer 230 may be provided as a "nonwoven integral drainage plate", and the nonwoven integral drainage plate is commercially available.

4 is a cross-sectional view of the vegetation mat 200 according to the present invention installed on the artificial ground 20, the net 400 made of coconut fiber is laminated in two layers.

The artificial ground 20 may be a roof of a building, an outer wall of the building, or a slope of a highway. The drainage layer 230 is positioned so as not to be fixed or moved on the artificial ground 20. The drainage plate 231 of the drainage layer 230 may have a base plate 231a, a plurality of protrusions 231b formed on the base plate 231a, and a drainage path 231c formed between the protrusions 231b.

According to the present invention, the vegetation layer 210 and the planting layer 220 formed integrally with each other on the drainage layer 230 are disposed. The vegetation layer 210 may simply be seated on the drainage layer 230 or may be fixed using any fixing means.

In the present invention, the wood chip 211 constituting the vegetation layer 210 and the filler 212 made of paper pulp is light in itself. Therefore, the load applied to the artificial ground 20 by the vegetation mat 200 is much reduced compared to the conventional vegetation structure 10 using soil as the vegetation layer. As a result, when forming a vegetation requiring a deep soil depth, by simply increasing the thickness of the vegetation layer 210 as necessary, it is possible to achieve the desired composition of the vegetation without applying an excessive load on the artificial ground (20). In addition, since the filler 212 made of paper pulp itself may contain an appropriate amount of water, it is possible to always supply adequate water to the roots of the growing seed 221. Therefore, since the structure of the filter layer 12, the waterproof layer 15, etc. which are the same as the conventional vegetation structure 10 is unnecessary, a simple structure and a lightweight integrated vegetation structure are realized.

In the present invention, the seeded seed 221 is rooted in the vegetation layer 210 by using the oxidized starch of the coating layer 222 as nutrients. Initially, rooting occurs through the filler 212, and as time passes, the wood chip 211 is decomposed so that rooting occurs through the wood chip 211. The porous wood chip 211 may include nutrients necessary for plant growth and may also decompose while supplying nutrients necessary for plant growth.

Hereinafter, a method for manufacturing a vegetation base material and a vegetation mat according to the present invention will be described.

5A to 5C are explanatory views illustrating a method of forming a vegetation base material or a raw material of the vegetation layer according to the present invention.

The wood waste or building waste wood 311a, which is produced after thinning the forest, is dried to have a water content of about 11%, and then crushed into fine wood fragments using a crusher 311b. Wood chips are approximately 1.5 to 2 cm in size. In this way, wood chips used as wood chips 311 are prepared. (See FIG. 5A).

Next, the collected waste paper, for example, the white paper 312a is cut and dissociated with water into the dissociator 312b. The paper pulp slurry 312 is removed from the white paper by cutting the dissociated paper 312b about 5,000 times. Form. The concentration of paper pulp in paper pulp slurry 312 is about 2.5-3.5%. (See Figure 5b)

Thereafter, as shown in FIG. 5C, the prepared wood chip 311 and the paper pulp slurry 312 are mixed to form a mixture 310. At this time, the wood chips and paper pulp slurry are preferably mixed in a weight ratio of 4: 6 to 6: 4. After the mixture 310 is formed in this way, the functional additive 314 is added to supply the water 313 and increase the function of the vegetation base material.

Examples of the functional additive 314 may include powder or granular activated carbon described above, a corrosion inhibitor, a colorant harmless to vegetation, a wet paper strength enhancer for paper or a surface size agent for paper. Powdered or granular activated carbon has the effect of suppressing the decay of the vegetation base material and improving the vegetation layer, and also acts as a corrosion inhibitor. The preservatives are commonly used in the art and are not particularly limited as long as they do not adversely affect vegetation. Paper wetting strength enhancers inhibit further dissociation of paper pulp slurries, increase the wet strength of paper pulp, and act as binders. Wet strength enhancer for papermaking is preferably added in an amount of 5 to 30% by weight of the weight of the finished vegetation mat before drying, when less than 5% by weight there is a possibility that the durability of the water is lowered due to a weak addition effect, 30 When exceeding the weight percent, it may adversely affect the growth of the plant. The papermaking wet strength enhancer is not particularly limited as long as it is commonly used in the art, so long as it does not adversely affect the growth of plants. On the other hand, the paper surface sizing agent prevents rapid drying of the finished vegetation base material, thereby ensuring that adequate moisture is retained in the filler (see FIGS. 2 and 3) or wood chips formed through dehydration in the paper pulp slurry. do. The surface sizing agent for paper is preferably added in an amount of 5 to 30% by weight of the dry weight of the finished vegetation mat. When it is less than 5% by weight, the additive effect is weak. Physical properties such as strength may be deteriorated. As a variant, the paper surface sizing agent among the functional additives may be applied to the surface of the vegetation base after forming the vegetation base 330 (see FIG. 7C).

The mixture 310 of wood chips and paper pulp slurry prepared in this way is introduced into a vegetation base material manufacturing apparatus to produce a vegetation layer of vegetation base material or vegetation mat. 6 is a perspective view showing a vegetation base material manufacturing apparatus 320 used in the present invention.

Referring to FIG. 6, the vegetation base material manufacturing apparatus 320 supports a molding die 321 into which the mixture 310 is injected, a pressing plate 322 matching with the molding die 321, and a molding die 321. And includes a barrel 323 for receiving the dewatered water from the mold 321.

The mold 321 is, for example, in the form of a rectangular box, and a plurality of drain holes 324 are formed at the bottom thereof to discharge water from the mixture 310. A plurality of crossbars 325 are formed at the upper end of the barrel 323 to support the mold 321.

7A to 7F are explanatory diagrams showing a manufacturing process of a vegetation layer of a vegetation base material or vegetation mat.

First, the mixture 310 of the wood chips 311 and the paper pulp slurry 312 is introduced into the forming mold 321. (See FIG. 7A)

Thereafter, the mixture 310 injected into the mold 321 is pressed by the pressing plate 322. At the same time the pressurization occurs, the water contained in the mixture 310 is discharged to the vat 323 through the drain hole 343 formed in the mold 321. As the mixture 310 is dehydrated and pressurized by the pressure plate 322, the wood chips 311 in the mixture 310 are compacted in the form of a rectangular plate-like body corresponding to the rectangular shape of the forming mold 321. At the same time, the paper pulp slurry 312 is a filler to fill the space between the wood chip 311, the paper pulp is stuck to each other as the moisture escapes to maintain the plate shape of the dense wood chip 311 (Fig. 2) And FIG. 3). Pressing by the pressing plate 322 may be performed by a power press device, or may be performed by installing a suitable weight on the pressing plate 322. (See Figure 7b)

After the pressurization and dehydration of the predetermined time is completed, the completed vegetation base material is released from the mold 321. 7C shows the completed vegetation base 330. The released vegetation base material 330 is dried at room temperature for a predetermined time.

Meanwhile, in the present invention, as already mentioned, the reinforcement made of coconut fiber is further included in the mixture 310, or the net made of coconut fiber separate from the mixture 310 is introduced into the mixture 310. By laminating at least one in the net can be laminated to the inside of the vegetation base material.

The drying vegetation base material 330 is filled in the space between the plurality of wood chips 331 and the wood chip 331 is densely packed in a rectangular plate shape to maintain a plurality of wood chips 331 dense in plate shape ( 332). Since the filler 332 and the wood chip 331 contain water, the vegetation base material 330 may be used as a vegetation layer of the vegetation mat.

In addition, the method of manufacturing a vegetation mat according to the present invention may further include a step of immersing the vegetation base material 330 after the drying process in a liquid fertilizer and then drying to further contain nutrients necessary for vegetation. The reason for the immersion in the liquid fertilizer only after manufacturing the vegetation base material 330 as described above may be a problem in durability of the vegetation base material 330 when the liquid fertilizer is directly added to the mixture 310. This is because the effect that can be obtained when the amount of liquid fertilizer is added may be reduced. Accordingly, after the vegetation base material 330 is manufactured and finished to dryness, the liquid fertilizer may be penetrated into the vegetation base material 330 by being immersed in the liquid fertilizer to contain nutrients of the vegetation. On the other hand, the pressure reduction immersion method is more preferable in order to improve the immersion process efficiency.

In addition, the vegetation base material 330 may be formed of a rectangular or square plate having a horizontal and vertical length of several meters or tens of centimeters depending on the size of the mold 321. The vegetation base material 330 formed in the size of several meters is installed on one or several on the artificial ground can be achieved the construction of vegetation layer for artificial ground greening. Vegetation base material 330 formed in the size of several tens of centimeters can be achieved by the construction of the vegetation layer for artificial ground greening by a large number is interwoven with each other on the artificial ground.

For example, the vegetation base material formed in the size of several tens of centimeters may be of the following two forms.

(1) Horizontal length: 200 mm, vertical length: 200 mm, height: 50 mm, weight before drying: 250 g, water added when the mixture is formed: 2000 ml

(2) Horizontal length: 200 mm, vertical length: 200 mm, height: 20 mm, weight before drying: 150 g, water added at the time of mixture formation: 2000 ml

Next, the seed 341 which requires the soil depth corresponding to the thickness of the vegetation base material 330 is sown on the dried vegetation base material 330. (See FIG. 7D)

Thereafter, the starch oxide aqueous solution 343 is applied to the surface of the vegetation base material 330 to which the seeds 341 are sown. As the starch oxide solution evaporates, the fixed starch oxide fixes the seeded seeds 341 to the top surface of the vegetation base material 330. The starch oxide aqueous solution 343 may be applied to the entire surface of the vegetation base 330 or to cover only the seeded seeds 341. (See Figure 7E)

In this way, a vegetation mat 340 is formed of a planting layer 340 including the seed 341 and a vegetation layer 330 for supplying the foundation, moisture and nutrients necessary for the vegetation of the seed. (See Figure 7f)

On the other hand, when the vegetation mat is formed in a small size of several tens of centimeters (hereinafter, the vegetation mat formed in a small size of several tens of centimeters is referred to as a "unit vegetation mat"), the operator has a plurality of unit vegetation mats It is possible to simply perform half-recording work of artificial paper by combining, and has the advantage of easy construction and repair.

8A to 8E are explanatory views showing a method of forming a unit vegetation mat according to the present invention.

The unit vegetation mat may be formed by cutting the completed vegetation mat 350 (see FIG. 7F) into a predetermined shape.

As shown in FIG. 8A, a rectangular vegetation mat 350 having a rectangular shape may be cut along a broken line orthogonal to each other to form a rectangular vegetation mat 361 having a rectangular or square tens of centimeter size. .

In addition, as shown in Figure 8b, the rectangular vegetation mat 350 is completed by cutting along a parallel dashed line in the horizontal direction and a wavy line in the longitudinal direction, the unit vegetation of several tens of centimeters in size The mat 362 may be formed. In this case, the unit vegetation mat 362 has a concave shape 362a on one side and an iron shape 362b that matches the concave shape 362a on the other side opposite to one side. Artificial soil recording is performed using a plurality of unit vegetation mats 362 in such a manner that the iron shape 362b of the other unit vegetation mat 362 is fitted to the concave shape 362a of one unit vegetation mat 362. It is possible.

In addition, as shown in FIG. 8C, the rectangular vegetation mat 350 having a rectangular shape is cut along the wavy lines in the transverse direction and the longitudinal direction, and the unit vegetation mat 363 having the size of several tens of centimeters is cut. Can be formed. In this case, in Fig. 8C, the unit vegetation mat 363 has concave-convex shapes 363a and 363b that can be matched with each other on the left side and the right side, and have concave-convex shapes 363c and 363d that can match with each other on the upper side and the lower side. Have The uneven shape 363c of one unit vegetation mat 363 is also adapted in such a manner that the uneven shape 363b of the other unit vegetation mat 363 is fitted to the uneven shape 363a of the one unit vegetation mat 363a. In the manner in which the uneven shape 363d of the other unit vegetation mat 363 is fitted, a plurality of unit vegetation mats 363 are interwoven with each other and artificial ground recording is possible.

The method of cutting the vegetation mat 350 of several meters in size to form the unit vegetation mat is not limited to those shown in FIGS. 8A to 8C, and the unit vegetation mats may be interwoven with each other or any shape in which an aesthetic appearance appears. Vegetation mat 350 may be cut to have.

In addition, the unit vegetation mat (361, 362, 363) is formed by cutting the vegetation base material 330 of several meters in size as shown in Figure 7c to form a unit vegetation base material It may also be prepared by seeding the seed on the upper surface and applying an aqueous solution of starch oxide.

On the other hand, the unit vegetation mat can be produced directly from the mold to the size of several tens of centimeters. 8D and 8E illustrate a mold for making unit vegetation mats of several tens of centimeters in size.

FIG. 8D shows the mold 321 'and the pressing plate 322' for manufacturing the unit vegetation mat 362 as shown in FIG. 8B. The forming die 321 'has an iron shape 321'a on one side and a concave shape 321'b that matches the iron shape 321'a on the other side opposite to one side.
