Description

Appealing apparatus for the slopes of lakes

The present invention relates to a lake slope recording apparatus for the purpose of water purification of rivers and lakes, restoration of aquatic ecosystems, and creation of waterside space. More specifically, the present invention is fixed to the inclined surface of one side of the non-perforated artificial plant island in which the vine plants are attached to grow ropes or water plants, and the other end so that the water plants are floating on the water surface. The present invention relates to an inclined tape recording device configured to be connected to a perforated artificial plant island. The appealing slope recording device of the present invention is an organic pollutant that causes eutrophication of the appeal by additionally planted plants with the greening effect of the appeal. It will have the effect of removing nutrients such as nitrogen and phosphorus.

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 flow into rivers and lakes by rainfall. Due to the inflow of pollutants, the concentration of pollutants in the water is increasing. 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. Odor caused by decayed substances may occur, and fish may be killed. 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.

Artificial plant islands have been developed to purify the water quality of rivers or lakes, and to create as many habitats as possible so that as many plants as possible can grow. Plants planted on artificial plant islands grow with nutrients from nitrogen and phosphorus in the water, thus eliminating nutrients in the water, supplying oxygen to the water, securing space for microorganisms to attach, and beautiful watersides. It can play a role in creating space. However, the conventional method using an artificial plant island has a problem that it is difficult to apply to the area exposed to the ocher area, which is difficult to form vegetation of vegetation in waterside parts such as lakes.

In addition, in Korea, there are many appeals made artificially by forming dams to use water as power generation, industrial and agricultural water. Most of the shores of natural appeals do not have steep slopes but have a gentle slope, but artificially constructed appeals often have steep slopes. This is due to the fact that the water level is significantly higher than the original water level artificially formed by the dam, so that the slope, which was previously a steep mountain slope, becomes the foot of the lake where the water level is increased by the dam. Such inclined surfaces are exposed to varying levels of water level. In particular, the inclined surface is always in the exposed state on the surface except for the rainy season such as rainy season, thereby causing a problem that the surrounding landscape is damaged. In order to solve this problem, various methods have been attempted to plant and plant plants on slopes. As a part of this, a method of planting a land plant or a waterside plant directly on a slope or sowing seeds of each plant on a slope has been attempted, but there are problems such as loss of rainwater. In the case of planting land plants directly on the slope, when the slope is completely submerged in the rainy season, land plants submerged in water for a long time will be decayed, even if the submerged soil is short, There is a problem that land plants will die by burying in the leaves. Another method is to wrap the nonwoven fabric on the inclined part and to plant several water plants. However, the nonwoven fabric mainly composed of chemical fiber yarns has been in the testing stage because it has little help in the plant's activity. In addition, a method of constructing a vegetation zone by mixing the adhesive component and the soil base material together with various plant seeds and fertilizers and packaging them on the inclined surface has been attempted.

Therefore, the present invention has been devised in consideration of the problems of the prior art, not only to prevent eutrophication of the appeal but also to maintain the inclined surface of the appeal despite the change in the water level of the appeal, planted waterside An object of the present invention is to provide an inclined greening device for appealing slopes that prevents plants from dying.

In order to achieve the above object, the present invention is fixed to the inclined surface of one side of the non-perforated artificial plant island (3) in which the rope (2) or the riparian plant (36) on which the vine plant (7) is attached and grown. The other end thereof is provided with an appealing slope recording device 1 configured by being connected to the perforated artificial plant island 4 configured to have the waterfront plant 45 planted and floating on the water surface.

That is, the appeal slope recording apparatus of the present invention is composed of a rope or a non-perforated artificial plant island and a perforated artificial plant island as its components, and the rope and the non-perforated artificial plant island are configured to cover the slope of the appeal. The stage is fixed to the inclined surface by the fixing device such as the fixed pile 6, and is formed to have fluidity according to the change of the water level of the appeal.The rope and the non-perforated artificial plant island are used alone or simultaneously according to the environmental conditions of the appeal. In addition, perforated artificial islands remain suspended in the water.

The rope is fixed at the top of one side of the slope of the lake, and the other side is connected to the perforated artificial plant island to provide a growing space for rooting and growing vine plants in a certain area of the slope. Ropes should be made of a stable material that is not only resistant to corrosion in water and excellent in durability, but also does not change its properties when exposed to sunlight for a long time, and polyethylene ropes, polypropylene ropes, etc. may be used, and preferably stainless Wire rope can be used.

The non-perforated artificial plant island used in the lake slope recording device of the present invention includes a foamed porous nonwoven fabric 35; A buoyant material (31) which does not form perforations of the olefin-based foam molding resin placed on the nonwoven fabric; A planting net 32 made of a natural vegetation material which is placed on the buoyancy material and is filled with natural vegetative fibers configured to slide the watered vegetation 36; A net (33) made of a synthetic resin material surrounding the buoyancy material and the planting net; It is configured to include a plurality of planting ports 34 are inserted into the mesh structure of the mesh planted plants. This is because the roots of planted plants are not exposed to the outside of the artificial plant islands, so even if the height of the artificial plant islands changes according to the fluctuation of the water level, the roots of the plants do not cause damage due to friction with the ground. It has the effect of enabling sustainable growth of plants.

Foam-molded porous nonwoven fabric has moisturizing power for a certain time due to capillary phenomena due to its weaving characteristics, so that the growth of planted plants is inhibited even when the level of appeal decreases and the non-perforated artificial island is in direct contact with the slope of the lake. It doesn't work. The olefin-based foam molding resin used as a buoyancy material is a material having excellent floating property and flexibility, and preferably, an expandable ethylene vinyl acetate copolymer (EVA) may be used.

In order to promote the growth of planted plants, the planting network that can cultivate watery plants such as reeds is made of fiber materials such as coconut fiber, coarse fiber, cotton yarn, and sulfur, which decompose naturally after 3 to 6 years. It is composed of a flat mat type filled with a mesh of natural fiber yarn such as martha, and is located on the upper part of the buoyancy material. Although the materials filled in the mesh are easily decomposable materials, the artificial plant islands according to the present invention can be used semi-permanently because the corroded soil is formed by the killing and decomposition of planted water plants. . The thickness of the planting net is preferably 5 to 10 cm so that the water plants can be supported.

Depending on the ecological characteristics and needs of the installation of the greening device of the present invention, only a rope or a non-perforated artificial island may be used, or both may be used to constitute a greening device.

The perforated artificial plant island used in the present invention includes a buoyant material 41 made of an olefin-based foam molding resin in which a plurality of perforations are formed; A planting network 42 of natural vegetation material, which is placed on the buoyancy material and is filled with natural vegetative fibers configured to slide the waterside plant 45; A net (43) of synthetic resin material surrounding and fixing the buoyancy material and the planting net; It is configured to include a plurality of planting port 44 is inserted into the mesh structure of the mesh planting the plant. The meshes used in the APR and the APR prevent the loss of vegetation and stably fix the planted waterside on buoyancy. Preferably, the net body manufactured by extruding 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 remain stable.

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