Description

  The present invention relates to a vegetation mat for river revetment and slope protection and a fixing device used therefor, and more specifically, it is provided on a slope, cut slope or slope of a river to prevent landslides and Enables vegetation to be effective, facilitates germination of seeds or promotes the matting of vegetation mats, and facilitates integration between slope and pasting structure so that greening can proceed quickly The present invention relates to a vegetation mat for river revetment and slope protection and a fixing device used therefor.

  Recently, as the use of land in the river basin has increased and urbanization has been promoted, the river environment has changed remarkably, and this kind of river environment change is aimed at flood control and water use. As the construction is carried out mainly on large-scale civil engineering works, it is further accelerated and the natural environment function of the river tends to decline.

  In addition to river water pollution, river vegetation as a component of the ecosystem and the density of fish and birds that live in the river are reduced, and the diversity of inhabiting animals is reduced. Function declined.

  In the case of urban rivers with high density of land use around rivers, the river environment has been changed by the construction of low waterways and watersides, the development of waterway lines, the construction of river dikes, etc. for flood control purposes, and the revetment of low waterways The part was made into a concrete block.

  For example, a concrete revetment block not only physically blocks river water from penetrating into the soil layer, but also dries out wet plants on the riverside of natural rivers, as the shadow provided by riverside vegetation disappears. The problem is that the temperature change becomes serious, the underwater underwater creatures, fish habitat, loses its function as a spawning ground, and even feeds around the riverside vegetation and damages the bird's habitat that hides in the vegetation cage There is.

  In addition, planting vegetation on the surface of cut slopes, such as banks and cuts, etc. that are made after civil engineering work, and slopes in embankment areas, as a way to prevent sediment from flowing out due to rainwater. Green.

  In the usual method, the tension turf construction method in which the turf is stretched directly on the slope with the turf stretched to a certain extent was mainly used. There was a difficulty in the supply and demand of turf because it was necessary to cultivate artificially. In addition, the natural environment could be damaged, and there was an uneconomic problem that required excessive labor and time during the construction process.

  As a method for solving such problems, a seed spray method has been proposed in which a seed mixed with an adhesive is sprayed on the slope so that the seeds can germinate and turn green. By closing the lid on the surface where the agent is sprayed and preventing evaporation of moisture, germination is promoted and, after germination, it can corrode and supply nutrients necessary for the growth of plants.

  However, the seed spray method simply sprays mixed seeds and plantes cut grass in a line, so it takes 4 to 6 years to fully stretch, and there is no auxiliary material to protect the slope, flooding Occasionally there is a disadvantage that the embankment collapses or is damaged by the increased water volume.

  Moreover, in order to adhere the lid to the surface of the cured adhesive, it was fixed using a fixed pile (iron plate anchor) provided with iron or plastic material, but the fixed pile was driven into the slope. After a long period of time, there was a state in which a part of the vegetation mat planted by the removal of the fixed pile was damaged while the roots of the planted herbs were not firmly rooted in the ground.

  And, as is well known, the cut slope has been constructed by constructing roads on parts of mountains, rivers, rivers, etc. in order to construct roads that will increase with the development of transportation in the 20th century. Formed on the periphery of the road.

  Such cut slopes are due to abnormal earth temperatures such as El Niño, La Niña, etc., and unpredictable storms have fallen, and 70-80% of the cut slopes are flowing, while other water is in the ground. Penetrates and penetrates into areas of weak soil quality on roads or cut slopes.

  If a large amount of water infiltrates into the ground in this way, the cut slope will collapse or break down, but of course, there will be an accident that the vehicle operating on the road will be buried or overturned due to the collapse of the slope, Vehicles will become impassable, and human property will suffer enormous property losses as well as human lives.

  The soil texture of such a cut slope is formed by excavating rocks or consisting of earth and sand, but the soil that makes up most of the earth and sand is the long-standing physicochemical and biological weathering of rocks. Generated by.

  In addition, the main components of soil generated from rocks include minerals that are weathered from rocks, organic matter formed from animal and plant debris, water generated during the decomposition of organic matter, carbon dioxide, oxygen, etc. It is included.

  Therefore, cut slopes such as mountains and rivers change to soil quality where plants can grow due to biological weathering of the soil only after about 5 to 10 years have passed since the construction of the cut slope.

  By cutting and planting ornamental plants such as turf and shrubs so that they are not damaged by rainstorms during the rainy season, torrential rain, etc., the cut slopes will not collapse or break. I am doing so.

  The greening method for the cut slope is to cover the cut slope, sow seeds of grass and shrub plants, and then cover the heat insulation such as straw and fiber net to maintain the humidity. The germinated seeds will grow and the cut slope will become green.

  However, such greening of cut slopes causes seeds to grow and seeds to grow, but it is raining and concentrating on slopes that have not yet taken root or where there are geological weak points. If heavy rain falls, the cut slope will be scoured, causing damage or collapse.

  Cut slopes are classified into ripped rocks (weathered rocks), soft rocks, hard rocks, etc., depending on the soil properties. In the case of ripped rocks and hard rocks, the cut slope is After installing a wire net or fiber net, cover with a soil composed of sewage sludge, food and drink sludge, industrial waste, sludge, sludge, etc., then set up a net or fiber net and sow seeds on it to plant green I let you.

  However, in order to fix the wire mesh and fiber mesh, it is fixed using a fixed pile (anchor pin) provided with iron or plastic material, but the fixed pile is driven into the slope for a long time. For example, there is a risk that the fixed pile will come off due to the weathering action of the ground and the multi-year temperature difference, and the fixed pile may come off. appear.

  In addition, after civil engineering work that cuts out a part of a mountain, it is required to green that part, and the greening of the cut part has many meanings in terms of preventing flood damage or landslides. have. There have been many proposals for such a greening structure, but the most prominent problem is that the greening structure cannot be supported more firmly on the slope after civil engineering work. That is, the whole or a part of the part greened by the storm is often washed away by water, and the greening business itself is not so reliable.

  The present invention has been created to solve such problems, and a vegetation mat is laminated in order to protect slopes generated during road construction and general civil engineering, that is, river revetments or slopes. After that, the reinforcement wire or the net-like member is brought into close contact with a fixing device, and the object is to provide a river revetment and a vegetation mat for slope protection, and a fixing device used therefor, which can firmly fix the vegetation mat to the slope. is there.

  Another object of the present invention is to sufficiently supply water or nutrients necessary for the growth of herbs, and after the growth of the herbs, a part or the whole of the vegetation mat is naturally decomposed. Accordingly, it is an object of the present invention to provide a river revetment and slope protection vegetation mat that can solve a fundamental problem of environmental pollution, and a fixing device used therefor.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 1, a riverbank and slope protection vegetation mat (hereinafter simply referred to as “vegetation mat”) 100 according to the present invention has a certain width and length, and is a first made of a biodegradable material. A biodegradation net 110 is provided, and a vegetation sheet 120 is provided which is laminated on the upper surface of the first biodegradation net 110 and has plant seeds attached to the surface.

  The vegetation mat 100 according to the present invention includes a burlap net 130 attached to the vegetation paper 120, made of coconut skin, and woven in a lattice shape using burlap, and on the upper surface of the burlap net 130. It has a coconut mat 140 that is laminated and densely formed by laminating coconut skins to a predetermined thickness.

  Further, the vegetation mat 100 according to the present invention is laminated on the upper surface of the coconut mat 140, and is laminated on the upper surface of the second biodegradable net 150 made of a photodegradable material and the rope shape. And a reinforcing wire 160a provided in the vertical or horizontal longitudinal direction of the slope.

  The first biodegradable net 110 made of the above biodegradable material is a biodegradable net that adds a certain amount of a natural substance such as starch to a biodegradable PE resin or PP resin so that the resin collapses. This means a woven state, and maintains the tensile strength.

  In addition, the riverbank and slope protection vegetation mat 100 according to the present invention has a structure in which the vegetation paper 120 and the burlap net 130 are organically coupled.

  Here, the vegetation paper 120 is prepared by adding fertilizer and wet material together with plant seeds mainly using papers such as Eisen paper and Korean paper in order to prevent detachment of plant seeds and increase germination rate. To make.

  Also, the burlap net 130 serves as a vegetation base material, and is provided integrally or separately on one or both sides of the vegetation paper 120 using coconut peel or burlap.

  And the said burlap net | network 130 secures the structural safety | security and durability of the coconut mat laminated | stacked on the upper surface of the said burlap net | network by woven and fixing a burlap in a grid | lattice form.

  The coconut mat 140 is densely formed by stacking coconut peels to a predetermined thickness, thereby preventing moisture from volatilizing from the ground and supplying moisture for germination of plant seeds on vegetation paper. It also provides the necessary organic fertilizer and heat retention effect for plant seeds, and provides a nutritional element or moisturizing effect for plant seeds or grown plants.

Further, the riverbank and slope protection vegetation mat 100 according to the present invention is laminated on the upper surface of the coconut mat 140 and includes a second biodegradation net 150 made of a photodegradable material. The 2 biodegradation net 150 uses a photodegradable material made of PP or PE resin containing a photocatalytic substance such as TiO ₂ .

  The riverbank and slope protection vegetation mat 100 according to the present invention is laminated on the upper surface of the second biodegradation net 150 and is provided with a reinforcing wire 160a having a rope shape. In the decomposition net 110, the layered structure of the second biodegradable net 150 is prevented from being detached after being constructed on the river revetment or slope, and the river revetment or law is prevented by a natural disaster after a long time. It becomes possible to prevent in advance that the earth and sand on the surface are separated or collapse.

  As shown in FIG. 2, instead of the reinforcing wire 160a, a net-like member 160b may be provided in which the surface of a metal material is coated with a synthetic resin and assembled in a net-like shape.

  Hereinafter, construction of the river revetment and slope protection vegetation mat 100 according to the present invention configured as described above will be described.

  As shown in FIGS. 3 to 8, the method for constructing a vegetation mat for river revetment and slope protection according to the present invention includes a step of preparing a ground surface, that is, a slope 105, on which a vegetation mat 100 is to be installed. Further, a step of laying a laminated structure including the first biodegradable net 110, the vegetation paper 120, the burlap net 130, the coconut mat 140, and the second biodegradable net 150 on the slope 105 is performed.

  Then, the reinforcing wire 160a is provided in the vertical or horizontal longitudinal direction on the upper surface of the laminated structure, and a step of forming a laminated structure of the vegetation mat 100 is performed. Next, the linear shape on which the reinforcing wire 160a is provided is used as a reference. The step of fixing the vegetation mat 100 with the fixing device 200 is performed. In addition, the method includes a step of covering the surrounding soil with the vegetation mat 100 fixed by the fixing device 200 as described above.

  Thus, in the process of constructing the river revetment and slope protection vegetation mat 100 according to the present invention on the slope, the fixing device 200 for fixing the vegetation mat 100 to the slope is a metal as shown in FIGS. Two plate-like wings 212 which are made of a material or a biodegradable resin, and are connected upward at an acute angle with respect to the square plate 211 at both ends of the square plate 211 having a through hole 213 formed in the center. The main body 210 comprised by these. Accordingly, the main body 210 forms a “V” -shaped cross-sectional structure.

  And the iron wire 220 penetrated by the through-hole 213 formed in the said square-plate shape 211 is provided. Such an iron wire 220 is inserted through a through-hole 213 formed in a square plate shape 211, and extends long on the upper side and is formed on the slope 105 as shown in FIG. 9. The number of holes formed is longer than deep.

  Further, a striking mechanism 230 is provided in the longitudinal direction of the iron wire 220 facing upward at the upper portion of the square plate shape 211 of the main body 210, and the striking mechanism 230 is in contact with the upper surface of the square plate shape 211 of the main body 210. As described above, the metal rod has a vertical cylindrical shape that is formed so that both sides thereof are inclined and has a handle 231 formed on both sides of the upper portion.

  As shown in FIGS. 6 and 7, the fixing device 200 includes a first biodegradable net 110, a vegetation paper 120, a burlap net 130, a coconut mat 140, and a second biodegradable net 150 on a slope 105. After laying the structure, the fixing device 200 is driven into a large number of holes formed in the slope 105.

  In such a process, as shown in FIGS. 10 and 11, the handle 231 of the striking mechanism 230 is gripped and struck with a hammer (not shown), and the fixing device 200 is placed in each of the many holes formed on the slope 105. It will be easier to type.

  When the fixing device 200 is thus installed, the striking mechanism 230 is removed and removed. Therefore, the iron wire wire 220 of the fixing device 200 is present on the upper surface of the second biodegradable net 150, and the iron wire wire 220 is fixed to the reinforcing wire 160a or the mesh member 160b. Construction of the vegetation mat 100 is completed.

  Further, as shown in FIGS. 6 to 8, all the constituent elements used in the vegetation mat 100 according to the present invention are provided on the slope as much as possible, and then fixed on the ground for a long period of time, and the reinforcing wire formed on the uppermost surface. By bundling 160a or net-like member 160b and preventing the earth and sand from flowing out or collapsing, it acts as a secondary defense means and can play a role in preventing landslides caused by natural disasters. .

  Not only that, all the components used in the vegetation mat 100 are made of biodegradable materials that can be corroded after a certain period of time, and thus can be used to protect the environment. I want to clarify that it is the road.

  On the other hand, the vegetation mat 100 can be used according to the flow rate regardless of various flow rates, and the vegetation mat 100 is fixed to fix the vegetation mat 100 regardless of whether the surrounding soil is covered with the reinforcing wire 160a or the mesh member 160b. Since the device 200 is driven into the ground, it has no special effect on the germination and establishment of plant seeds.

  Therefore, the riverbank and slope protection vegetation mat 100 according to the present invention constructed as described above has a thick vegetation base in which the coconut mat 140 made of coconut long fibers has a thickness as described above. Since it is a material, it has excellent moisturizing power, can maintain a certain strength in the initial stage of construction, and exhibits excellent functions for plant seed survival and prevention of loss.

  The coconut mat 140 has an excellent moisturizing power and functions to protect plant roots from drying and erosion. Then, in order to double the reinforcing effect of the coconut mat 140, the vegetation mat 100 is increased in strength by being laminated on the upper surface and providing the photodegradable second biodegradable net 150 and the reinforcing wire 160a or the net-like member 160b. Can do. Accordingly, it is possible to prevent the bank from being lost during a flood and to maximize the durability of the vegetation mat 100 itself.

  Further, the vegetation mat 100 can be easily provided with a vegetation space by planting the vegetation mat 100 by being fixed to a river or a slope by a solid fixing device 200, and is economically and effectively designed. Is possible.

  And since the vegetation mat 100 of the present invention uses only environmentally friendly materials, the first and second biodegradable net layers 110 and 150 on the surface are photodegraded or biodegraded if exposed for a long time after construction. Even if the coconut mat layer disappears due to corrosion, the grass and wild flowers are already rooted deep on the surface of the mesh, and the greening is completed vigorously. In addition, the slope protection function can be effectively performed.
