Description

VEGETATION MAT INCLUDING TWO SEED LAYERS}

The present invention relates to a vegetation mat for vegetation greening having two seed layers, and more particularly, a vegetation comprising two seed layers according to the size of seeds which can uniformly vegetate and plant various species on the slopes. It is about a vegetation mat for greening.

In general, when new roads or buildings are built, slopes are generated by cutting some of the natural parts as necessary. These slopes are the first visually recognized obstacles and are very important as visual and ecological connection with the surrounding landscape. However, because the slope is formed by artificial damage of the stable surface formed by adapting to long-term climate change such as typhoon, heavy snow, rainfall, etc., slope greening occurs due to instability such as groundwater movement change, rainfall, air erosion and collapse, and bandage. Is an essential part of structural stability of the slope and prevention of erosion.

Currently, the slope greening method that is currently used was the method of spraying grass seed, but to plant seeds or planting seedlings on large slopes unnecessarily extends the air gap during the construction of the landslide, and exhausts labor inefficiently. The construction method and construction structure of the conventional landslide construction had a problem of generating unnecessary costs for greening.

In order to solve this problem, a number of patents including 10-0294516 and the like apply an adhesive material to a sheet, and then, using a vegetation mat manufactured by laminating a composition mixed with seeds and fiber coconut, and then bonding the sheets on it. It was used for slope greening and greening of general plants, but spraying seeds on the sheets eventually spreads seeds evenly on small sheets, making it difficult to spread the seeds evenly on the sheets. A problem arises that it is difficult to make.

In order to solve this problem, it has been proposed in the slope greening method using a vegetation rope in which the soil composition containing the seed is inserted into the vegetation rope, specifically, in the Republic of Korea Patent Registration 10-0719078 as shown in Figures 1 and 2 After the seed rope 20 is manufactured and fixed using the connecting straps 11 to the support net 10, a method of using such a net for greening is provided, and in Korea Patent Registration 10-0714674, as shown in FIG. As described above, a method of twisting a separately produced seed rope is provided.

Even when such a vegetation rope is used, since the vegetation rope made after making the vegetation rope must be connected to the support net by means of a separate connection cord such as a thread, a lot of labor is required in the connection work between the rope and the support net. In the case of the made net, when the connection between the rope and the net is unstable, the connection is disconnected from the support net, causing a positional flow, which causes a problem of deteriorating the stability for the recording. In addition, when mixing 3-6 kinds of seeds in the vegetation rope, there is a difference in germination rate according to the mixed seeds, so that all the mixed seeds are not germinated. There was a problem that can not record.

The present invention is proposed to improve the above problems in the prior art, the vegetation comprising two seed layers of vegetation rope-type first seed layer and sheet-like second seed layer according to the size and germination needs of the buried seed It is a technical problem to provide a mat.

In addition, the present invention by constructing a vegetation net including the vegetation net having the vegetation rope insert and the double seed layer of the vegetation including the seed, the plant seed tailored slope recording to enable uniform restoration of various species It is a technical task to provide a method.

The present invention provides a vegetation mat comprising two seed layers, a vegetation rope type first seed layer and a sheet type second seed layer, in order to solve the above problems.

The vegetation rope type first seed layer of the vegetation mat of the present invention contains seeds having a size of 1 mm or less, and the sheet type second seed layer includes seeds having a size of 1 mm or more.

The vegetation rope type first seed layer of the vegetation mat of the present invention includes a support net having a vegetation rope insert and a vegetation rope inserted into the vegetation rope insert.

Vegetation ropes included in the vegetation rope-type first seed layer of the present invention is a mixture of vegetation members and seeds containing the nutrients for germination is made by wrapping the rope in the vegetation, or the vegetation member and seeds in the outer vegetation The mixture including the is filled.

The support net of the vegetation rope-type first seed layer of the present invention is more environmentally friendly to make a fiber made of biodegradable natural materials such as PLA (biopolymer), jute, and the like.

The support mat of the vegetation rope-type first seed layer of the present invention includes a vegetation rope insert and includes an appropriate number at appropriate intervals for the region to be constructed.

In the sheet-like second seed layer of the present invention, the vegetation member including the nutrients for germination and the mixture including the seeds are laminated on the lower vegetation, and then the upper vegetation is laminated on the upper vegetation.

According to the present invention as described above, according to the size of the seed is composed of two seed layers of vegetation rope form and sheet form to increase the germination rate of the seed and to increase the greening efficiency by uniformly recording a variety of seeds.

In addition, since the vegetation rope is inserted into the support net having a separate vegetation rope insert, the vegetation rope is prevented from flowing, so that the state of the vegetation rope can be maintained at a predetermined interval so that the whole germination is made. It does not require a separate connection process of the workability and workability at the same time when installed on the slope has the effect of preventing the slope of the slope by the vegetation rope insert.

In addition, by using the vegetation rope type first seed layer and the sheet type second seed layer together, the plants germinated from the sheet type second seed layer can be filled within the interval maintained by the vegetation rope type first seed layer, so that the overall germination can be maintained. Will be.

In particular, even seed of less than 1 mm contained in the vegetation rope is protected by the vegetation rope insertion part to prevent the loss of seeds while preventing the adverse effects of seed loss or growth during the growth of the seed germination In addition, small plant seeds of less than 1mm and plant seeds with high moisture demand are filled in the vegetation rope type first seed layer to help improve germination rate.

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

The vegetation mat including two seed layers of the present invention includes two seed layers of the vegetation rope type first seed layer and the sheet type second seed layer.

In the vegetation net including two seed layers of the present invention, the seeds inserted into the vegetation-rope type first seed layer and the sheet-type second seed layer are various kinds of plant seeds in accordance with the slope environment in which the net of the present invention is constructed. Its type can be determined, but the seed mixed with the vegetation rope of the vegetation rope-type first seed layer having the vegetation rope insert is mixed only 2 to 4 kinds of seeds having a size of 1 mm or less, and embedded in the sheet-shaped second seed layer The resulting seeds consist of seeds whose size is at least 1 mm.

In the case of a seed having a size of 1 mm or more and a seed of 1 mm or less, the seed having a size of 1 mm or less is produced in a vegetation rope by mixing with the vegetation member because the seed is likely to be lost when the sheet is made. Insert the rope into the support net having the vegetation rope insert to make the vegetation rope-type first seed layer, and for seeds of 1 mm or more in size, use a seed attachment adhesive made of a material such as natural pulp paper that can be decomposed when supplied with moisture. After attaching to the sheet to form a sheet-like second seed layer, it can be laminated on the slope with the vegetation rope-type first seed layer having the vegetation rope insert portion.

Specific examples of the seed having a size of 1 mm or less include buddha, nectar, fern, wormwood, bellflower, and the like, which mainly corresponds to a dicotyledonous plant of a genus plant. Specific examples of seeds having a size of 1 mm or more include reeds, silver grasses, silver grasses, dianthus, sheep grasses, sedges, etc., mainly monocotyledonous plants.
