Description

Non-skeletal artificial islands {An artificial plant-island without frameworks}

The present invention relates to an artificial plant island for the purpose of water purification of rivers and lakes, restoration of aquatic ecosystems, and creation of waterside space. More specifically, by using an olefin-based foamed resin having excellent buoyancy as a floating body, a plurality of perforations are formed therein so that the roots of aquatic plants can reach the water, and a flat mat type of a natural vegetable material on the floating body. After positioning the vegetation base material, and relates to the non-skeletal artificial plant island formed integrally wrapped with a synthetic resin mesh and the vegetation base material.

As industrialization progresses, the amount of pollutants such as dust, nitrogen dioxide, and sulfur dioxide increases in the air, and these substances are suspended in the air and are introduced into rivers and lakes by rainfall. In addition, the concentration of pollutants in the water is increasing due to the inflow of domestic sewage and factory wastewater into the river. In particular, nutrients including nitrogen compounds and phosphates are inorganic elements necessary for the growth and growth of microorganisms causing organic decomposition, and are elements that must be continuously supplied for biological cell formation and life energy acquisition. However, excessive nutrients such as nitrogen and phosphorus cause eutrophication exceeding the limit of the self-cleaning ability of the aquatic ecosystem, and over-growth of phytoplankton in the water causes the turbidity of river water and the like to deteriorate. Odor occurs and can cause fish to die. Therefore, it is desirable to maintain a balance such that the amount of nutrients present in aquatic ecosystems such as rivers and lakes does not exceed its own purification capacity.

In order to purify the water quality of rivers and lakes and to create a habitat for various organisms, it is necessary to create an environment where as many plants as possible can grow. Plants grow with nutrients from nitrogen and phosphorus in the water, thus removing nutrients from the water, supplying oxygen to the water, securing space for microorganisms to attach, and creating a beautiful waterfront space. Since it is possible to secure the growth space of a plant, it is desirable. However, since plants can only be vegetated only on waterfronts where water and land are in contact with each other, a method of floating artificial plant islands on water has been developed in order to secure sufficient growth space for plants. Conventionally, artificial plant islands have been developed in various forms and structures according to the types of floating bodies and vegetation base materials.

At present, the Korean Patent Application No. 20010043609 (raft type artificial plant island) that uses a soil as a vegetation base to maintain buoyancy by arranging a plurality of hollow tubes sealed at both ends in the form of a raft, Korean Patent Application No. 19980012959 (aquatic plant cultivation device) using a floating material made of plastic material and a planting groove and using a block structure vegetation made of fibrous material. Registered Korean Utility Model Application No. 20000016990 (water bank for water purification of freshwater lakes) using float as a floating material and vegetation base material, Korean patent application using bamboo as a buoyant material and flat mat made of vegetable natural fiber yarn as vegetation base material 19980028643 (artificial buoy for water purification of freshwater lakes) is known.

However, all of the existing artificial plant islands as described above are not easily transported and installed because the frame for fixing and preserving the vegetation base material or the floating body for supporting the same is made of a hard material such as metal, and is damaged due to impact. In particular, the water environment in which artificial plant islands are installed is used for existing artificial plant islands because of the large inflow of runoff during flooding and the constant physical waveforms due to tidal currents, flow rates, waves, and typhoons. The skeletal structure and the rigid material that have come had inherent fear of breakage.

Therefore, it can be said that a floating artificial plant island having a non-skeletal structure having excellent buffering capacity against external impacts is more suitable for an aquatic environment in which dynamic physical energy is always present. In addition, as a buoyant material, a highly durable synthetic resin-sealed tube (eg, PEM tube) has been used, which has a disadvantage in that it is bent in the summer when exposed to direct sunlight or high temperature and does not provide an environment-friendly landscape.

Korean Patent Application No. 20010043609 uses a metal material as a frame for fixing and preserving vegetation base material, which is cumbersome to manufacture, economically inefficient, and there is a risk of plant sinking when the bond with the floating body is dismantled. Since the soil is used as a vegetation base material, when the body part and the soil part are disconnected, there is a problem that a separate measure for water retention is required. When the body part and the soil part are open, they are contained in the soil. Nutrients can leak into the body of water, causing more serious eutrophication.

In the case of Korean Patent Application No. 19980012959 and Korean Utility Model Registration Application No. 20000016990, since the plant has a closed structure without voids or gaps connected to the waterbody, except for the place where the planting groove is formed, Other than the planting department, there is a problem that vegetation is not further divided and expanded.

In the case of Korean Patent Application No. 19980028643, a natural floating material such as bamboo is not harmful to the environment and economically reasonable, but it is a floating material using a natural material that can be easily degraded. There is a problem that the life is shortened.

In addition, an aluminum steel pipe may be filled with foamed urethane or a protective plate outside the styropole to be used as a floating body of an artificial plant island, but the former is uneconomical, and the latter is structurally safe when styropol is exposed to sunlight. This can be a problem.

Accordingly, the present invention has been made in view of the problems of the prior art, the object of the present invention is stable, easy to install and economical, the structure does not change even under changes in the water environment and climate change, prolonged daylight exposure. To provide a non-skeletal artificial island.

The object of the present invention, in the present invention, a plate-like floating body (2) made of olefin-based foamed resin material formed with a plurality of perforations 21 to guide the roots of aquatic plants into water; A flat mat-like vegetation base material (1) on which the plant-based natural fiber yarns that adhere to the aquatic plants are placed on the floating body having a structure filled in a net; The floating body and the vegetation base material were achieved by providing a non-skeletal artificial plant island composed of a single body by wrapping and fixing the net with a synthetic resin material 3 and sewing the opening.

The present invention supplements the structural disadvantages of existing skeletal artificial plant islands for water purification, river ecosystem restoration, and waterside space creation in rivers and freshwater lakes, and the term 'skeletal artificial plant islands' used herein refers to vegetation. The base material (1) or the floating body (2) for supporting it or the outer frame refers to an artificial plant island made of a hard material, the term 'non-skeletal artificial plant island' refers to the vegetation base material (1) ) Or floating body 2 is used to mean an artificial plant island not configured in the form of a frame.

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

Figure 1 shows a non-skeletal artificial plant island according to a preferred embodiment of the present invention, Figure 1a is a perspective view of the vegetation base material (1) using a natural vegetable material, Figure 1b is an olefin foam foam of the plate shape It is a perspective view of the float 2 using resin, and FIG. 1C is a cross-sectional view of the non-skeletal artificial plant island in which the vegetation base 1 and the float 2 are integrated into the synthetic fiber net 3 to be integrally formed.

Vegetation base material (1) capable of sliding aquatic plants such as reed (1) is a flat mat or rubberized with fibrous materials, such as coconut fiber, filled with a mesh of natural fiber yarns such as coir fiber, cotton yarn and jute yarn. Coconut fiber sheet (rubberized coconut fiber sheet) is made of environmentally friendly and nature-friendly material manufactured by incorporating rubber into coconut fiber, it is located above the float (2). The materials filled in the mesh mat are easily decomposable materials, but the artificial plant islands according to the present invention can be used semi-permanently because the environment in which another plant can grow by killing and decomposing planted aquatic plants. . The thickness of the mesh mat is preferably 5 to 10 cm so that aquatic plants can be supported.

In the present invention, as the floating body 2, unlike conventionally known techniques, an olefin-based foam molded resin sheet material having excellent floating property and flexibility is used without making a frame of a certain shape made of metal or wood. Preferably, an expandable ethylene vinyl acetate copolymer (EVA) is used as the suspension.

EVA is a kind of polyethylene resin produced from a high pressure polyethylene polymerization apparatus, and has excellent flexibility in room temperature and excellent elasticity as compared with other types of polyethylene resins. Since EVA material forms a fine uniform independent bubble structure, it is light and easy to mold and has excellent weather resistance compared to rubber, and is currently widely used as a shoe sole material, and is also used as an agricultural film. The present inventors pay attention to the characteristics of EVA as described above, and use EVA as a float, so that the breakage and loss of the float (2) or the vegetation base material (1) due to the collision of blue or artificial plant islands during rainstorm or storm. It provides a non-skeletal artificial plant island without the risk of

In addition, in order to prevent the loss of the vegetation base material (1), and to ensure that the planted waterfront plants can be stably fixed on the float (2), the vegetation base material (1) and the float (2). It was formed in one piece using a synthetic resin net (3). This is another characteristic structure of the present invention, since the vegetation base material 1 and the floating body 2 are each formed in a frameless structure, and do not form a separate binding port and bind using a net 3. It is. Preferably, the net | network manufactured by extruding the medium and high density polyethylene resin (HDPE, MDPE) which is a material excellent in durability and weatherability is used. Since medium and high density polyethylene resins are characterized by high hardness, excellent impact resistance, heat resistance and weather resistance, they are not only damaged by the net itself due to blue waves and impacts, but also are less deformed by light. Even if you receive the artificial plant islands will be stable. In addition to medium and high density polyethylene resins, synthetic resin-based meshes such as nylon nets, PE nets, nacelle nets, and PP nets with excellent durability and workability can be used.

Figure 2 is a preferred embodiment according to the present invention, a process diagram showing the manufacturing process of the non-skeletal artificial plant islands. As shown in Figure 2, the non-skeletal artificial plant island according to the present invention, after placing the flat mat mat vegetation base material (1) of the natural vegetable fiber material on the float (2), the synthetic resin without going through a separate fastening process After wrapping the vegetation base material (1) and the float (2) with a net (3) is finished by sewing the opening with a fastening means such as synthetic resin, fishing line, rope of the same material as the net (3). Therefore, the manufacturing process of the frame or the manufacturing method of the floating body (2) formed with the frame for the preservation of the vegetation base material (1) is not necessary, not only the manufacturing process is simple but also the cost, such as the cost of manufacturing the frame is reduced, Time savings can also be achieved. In addition, the replacement is easy and easy even when the artificial plant island is broken.

Between the net (3) of the non-skeletal artificial plant islands prepared through the process shown in Figure 2 is inserted a plurality of ports for planting aquatic plants, the pot is also plant-based natural as the vegetation base material (1) It is made of fiber and fills the soil with soil to plant plants.

FIG. 3 shows a case in which a plurality of artificial plant islands are interconnected in order to obtain an aquatic plant planting area as necessary when the artificial plant island according to the present invention is applied to an actual body of water. When it is necessary to expand the planting space of aquatic plants by connecting a plurality of artificial plant islands, each artificial plant island made of a predetermined unit area as shown in FIGS. 1 and 2 has a main rope 5 of the artificial plant island. Penetrating through the floating body (2), to form a connecting ring 51 at its end and then connecting the connecting ring 51 to each other with a connecting rope 52 to connect a plurality of artificial plant islands or connecting rope ( 53) to connect and fix to the fixed anchor (7).

As a result, a stable artificial plant island system can be obtained, and since the external impact such as flow velocity and blue waves only affect the rope, it is possible to drastically reduce the direct influence on the non-skeletal artificial plant island.

The main rope 5, the connecting ring 51 and the connecting ropes 52 and 53 are made of stainless steel or synthetic resin, preferably polyethylene and polypropylene, which are resistant to corrosion in water and excellent in durability.

4 is a use state diagram showing a state in which the artificial plant island is fixed by using the anchor anchor 7 on the bottom so as not to flow out of the place where the artificial plant island according to the present invention is installed. As shown in FIG. 4, the water level regulator 6 is connected to both sides of the non-skeletal artificial plant island via a connecting rope 53, and is installed on the bottom surface of a river or the like through the connecting rope 53. By being connected to the anchoring anchor 7, it did not deviate significantly from an initial installation position, and it did not submerge below the water surface for more than a predetermined depth in spite of the fluctuation of the water level.

Although only a rectangular artificial plant island is shown in the drawing, this is only an example, and a modification to a circular or elliptical shape is also possible, and the number of artificial plant islands installed in the aquatic ecological park can be added or subtracted as needed. In addition, in the case of the water level regulator 6 shown in Figure 4 can be installed and used as many as necessary around the artificial plant island. In other words, the scope of the present invention is not limited to the above-mentioned matters, and the scope of the present invention includes those to those skilled in the art to which the present invention pertains, such as a simple change in shape.

As described in detail above, the present invention is to form a floating body (2) with a natural vegetable flat mat-like vegetation base material (1) and a plate-shaped foam molding resin excellent in buoyancy, which is a medium-high density polyethylene or synthetic resin By integrally forming using the net (3), it is not necessary to manufacture the frame for the preservation of the vegetation base material 1 or the manufacturing process of the floating body 2 formed with the frame, the manufacturing process is not only simple, but also the frame production cost Its cost is reduced, and the time required for manufacturing is also saved, and it is easy and easy to replace even when the artificial plant island is broken. In addition, the present invention significantly reduces the direct impact on non-skeletal artificial plant islands because external impacts such as flow velocity, blue, etc. only affect the ropes in fixing and interconnecting, thereby reducing the risk of damage. Since it is effective to provide, it is a very useful invention in the water purification industry, such as rivers and lakes, water conversion landscape composition industry.
