Description

Vegetation mat assembly and construction method {STRUCTURE OF VEGETATION MAT AND EXECUTION PROCESS}

The present invention relates to a vegetation mat assembly, and more particularly, to an environment-friendly vegetation mat assembly and its construction method that can fix the vegetation mat on the ground with only an anchor without the need for a separate fastening means.

In order to prevent the loss of the slope of a river, a mountain, or a bank, conventionally, a method using a vegetation block or a vegetation mat is introduced with a seed spray.

Seed spraying is a method of preserving the vegetation base by spraying and preserving the vegetation base by spreading the roots of herbs. The seed spray method requires a large amount of alien herbaceous plants to prevent the erosion of the base, as well as the natural vegetation is difficult. In addition, large seeds are separated from the base or exposed to the outside, so the use of small seeds has a problem in the determination of seeds. In addition, because of the large amount of herbaceous vegetation, there is a problem that the native growth of the tree is not secured because the growth of woody plants is impossible. In addition, there is a risk of erosion because it is exposed to the surface of the growth base agent. In the cold and high cold regions, the growth base is weak in the East Sea, and there is a risk of erosion even during the thawing season.

In addition, the construction of the seed spray when the rain is practically impossible, there is a disadvantage that you need to use a separate soil. In addition, in order to seed spray, not only a separate large machine should be used, but also the work space should be large, and there is a problem in that scattering dust is generated due to a large amount of base material that wastewater is generated during work.

In conclusion, the loss of vegetation-based agent occurs, the germination rate is significantly different from site to site, and over time after construction, there is an aesthetic problem due to defoliation of herbaceous plants.

The vegetation block is generally used to form a small space for plants to grow in the center of the concrete block, and to grow the plants by planting the small space inside. However, this method is environmentally friendly today because the vegetation block itself is a concrete product, which has a negative effect on the plant, the number of planted plants is relatively small, and also has a certain limit on the growth of planted plants. It is not treated in a way.

On the other hand, the construction method using the vegetation mat is a light material and the installation speed is faster and simpler than other constructions.In addition, since the vegetation mat protects the existing vegetation, vegetation is possible even after several years. It has the advantage of being applicable regardless.

By the way, the construction method of the vegetation mat has the disadvantage that the vegetation mat can be stored indefinitely because the plants to be planted are included in the vegetation mat in advance, and also the plants grow arbitrarily inside the vegetation mat during storage. There are also disadvantages. In addition, the vegetation mat covering has a problem in that it is difficult to grow woody plants due to irregular component decomposition of the vegetation mat, while seed or vegetative supplements are produced by being injected into the vegetation mat by rainfall or heavy rain. The construction method of the problem is that there is a possibility of deviation of the form by wind or rainfall after construction. In the cold and high cold regions, the soil layer of the vegetation mat plays a role of a heat insulating agent, but there is a problem in that the thickness is thin and a large role cannot be expected.

On the other hand, if you look at the construction method of the slope, which is generally performed today, stop the slope, then put a vegetation mat on it, cover it again with a wire mesh, then fix it, plant it, etc. have.

This series of actions is incredibly difficult and difficult because workers must perform on slopes rather than plain ground.

In addition, the construction method of the vegetation mat has a problem in that it is not possible to construct in rainy weather, as well as to use a dedicated soil to cover the vegetation mat.

As described above, the conventional inclined surface construction method has a disadvantage in that the workers must proceed all the processes on the inclined surface having a predetermined angle.

Accordingly, an object of the present invention is to provide a method for constructing an eco-friendly eco-friendly inclined surface which can minimize the work going on the inclined surface, and can be quickly and efficiently constructed in the vicinity of a river, embankment, highway, or mountain slope. .

In addition, another object of the present invention to provide a customized vegetation mat structure suitable for the above construction method.

In order to achieve the above object, the present invention, the first vegetable fibrous layer formed by forming the bottom layer in the layer of vegetable fibers, the greening agent layer formed on the first vegetable fibrous layer and composed of seeds for ground greening, vegetable A vegetation mat comprising a second vegetable fibrous layer formed so that fibers cover the greening agent layer in layers, and a cornet layer fixedly supporting the second vegetable fibrous layer; And a longitudinal insertion anchor inserted through the vegetation mat and the ground to fix the vegetation mat to the ground, between the support extending in the vertical direction from the top of the anchor, and the other end of the end connected to the top of the anchor between the support. A vegetation mat structure comprising a fixed unit including a hook portion formed to extend a predetermined length downward and a plate-like support portion elastically coupled to the lower predetermined position of the anchor so as to be bent up and down like a wing Provide construction method.

Including the greening layer in the vegetation mat does not require the step of injecting the greening agent during construction, and it can shorten the air because it can be germinated in advance if necessary.

Various designs are applied to the greening layer to arrange seeds so that various designs can be applied to the slopes.

The use of natural plant materials can fundamentally block soil water pollution.

Since it can be firmly fixed by simply inserting the fixing unit, it is possible to omit a separate work, thereby simplifying construction.

The vegetation mat 100 includes a first vegetable fibrous layer 110, a greening agent layer 120, a second vegetable fibrous layer 130, and a coret layer 140.

The first vegetable fibrous layer 110 is formed by forming a bottom layer of vegetable fibers in a layered manner, and is in contact with the ground. The first vegetable fibrous layer 110 is preferably woven from fiber of a vegetable material such as rice straw, palm pulp, barley, corn stalk, hay, or a non-woven sheet. The first vegetable fibrous layer 110 may cover the ground during construction to prevent the water from being released from the ground, and may help seed germination and growth of the greening agent layer 120 formed thereon by adding a growth promoter. have. Since the first vegetable fibrous layer 110 is composed of coarse vegetable fiber, when the seeds germinate, the roots pass through the first vegetable fibrous layer 110 to extend to the ground below.

The greening agent layer 120 is formed on the first vegetable fibrous layer and consists of seeds for ground greening. The greening agent layer 120 may germinate before construction or after germination.

The second vegetable fiber layer 130 is formed so that the vegetable fibers cover the greening agent layer in layers. The second vegetable fibrous layer 130 may be composed of the same components as the first vegetable fibrous layer 110. The second vegetable fibrous layer 130 may also be added to the seed growth promoter to help seed germination and growth of the greening agent layer 120, and is composed of coarse vegetable fiber so that the shoots of the germinated seed may pass through and grow. .

The first vegetable fibrous layer 110 and the second vegetable fibrous layer 130 are composed of a vegetable material, and after a predetermined time, the first vegetable fibrous layer 110 and the second vegetable fibrous layer 130 are decomposed by microorganisms present on the ground, and thus can be used as a nutrient source of the plant.

The coret layer 140 is disposed on the second vegetable fibrous layer 130. The coret layer 140 fixedly supports the underlying layers.

Each layer constituting the vegetation mat is laminated and then coupled by a separate fastening means (not shown). It is preferable to use a hog ring (C ring). Since the vegetation mat is composed of the first and second vegetable fibrous layers 110 and 130 having flexibility as described above and the coret layer 140, the vegetation mat according to the present invention can be folded or rolled into a cylindrical shape, so storage and transportation are easy. It is easy.

Insertion anchor 510 is preferably formed in the shape of the length that can be inserted into the vegetation mat 100 to the length of more than a predetermined depth of the ground.

The support portion 550 is formed of the vegetation mat 100 stacked from the top of the insertion anchor 510 so that the support portion 550 is positioned in the ground below the vegetation mat 100 to fix the vegetation mat 100 to the ground. It is preferably located below the height. As shown in FIGS. 6 and 7, the support part 550 is preferably formed with an anchor 510 insertion hole 551 at the center of a rectangular plate of a metal or synthetic resin material having a restoring force after bending.

A pair of blocking portions 530 are installed at predetermined lower portions of the insertion anchor at predetermined intervals, and the support portion 550 is coupled between the pair of blocking portions. The stopper 530 is preferably formed of a nut and inserted into and fixed to the anchor 510. The blocking part 530 serves to block the support part 550 from being bent at a predetermined angle or more when inserted into the ground during construction.

The vegetation mat structure construction method configured as described above is as follows.

The vegetation mat is prepared in advance as described above, and the produced vegetation mat is placed on the ground for greening. The ground may be an inclined surface.

In order to fix the vegetation mat disposed on the ground, a fixing unit is inserted to pass through the vegetation mat 100 and the ground B at a predetermined position of the vegetation mat, but the support rod 520 and the hook portion 521 ) Is inserted into a position capable of fixing a part of the net of the core net layer 140. As shown in FIG. 5A, when the fixing unit 500 is pressed in the direction of arrow a, the anchor 510 is inserted through the vegetation mat 100 and the ground B. FIG.
