Abstract

The construction of concrete retaining wall, gebion retaining wall, block retaining wall, stonework, concrete block, and gabion has been mainly used for slope stability and dimensional stability when constructing road cut soil slopes or river embankments. Were irrelevant methods. Recently, as the importance of environmental preservation and ecosystem restoration has emerged, new eco-friendly construction methods and various materials have been requested in consideration of site characteristics.

Accordingly, the present invention is a non-woven fabric bag made of polyester filament nonwoven fabric (geotextile for civil engineering) and made of seeds by attaching seeds to the dietary habit, GABION TYPE (GABION TYPE) or quilt wire mesh (METTRESS) TYPE) to form gebion structure by embedding soil on site in this nonwoven vegetation sack, and then form the foundation or river embankment of cut soil slope by stacking the gebion structure step by step. It is formed in a structure that stabilizes the slopes of cut soils or river banks by spreading the gebion structure horizontally and continuously, and the excellent durability of wire mesh (gebion or quilt type) and excellent flexural properties and filled soil are not released to the outside. Therefore, it is structurally stable and its construction is simple by utilizing the soil generated in the field. It is attached to the seed bags are eco-friendly ecological restoration process that vegetation colonization in early without any sowing.

Description

ENVIRONMENTAL RESTORATION TECHNIQUES BY NONWOVEN GEOTEXTILE VEGETATION SOIL-BAGS}

In the meantime, we have mainly used structures such as concrete retaining wall, gebion retaining wall, block retaining wall, stonework, concrete block, and gabion for slope stability and dimensional stability when repairing road cut soil or river embankment. Were irrelevant methods. That is, there has been a problem that the ecosystem is destroyed because there is no space (HABITAT) that the vegetation can stick to. The existing gabion method and gebion retaining wall stone filling, which have been frequently used in rapid river sections where durability and flexibility are concerned, cause the destruction of aquatic ecosystems by indiscriminately collecting the stones on the riverbed and prevent the vegetation from sticking. there was. As the importance of environmental conservation is emphasized in recent years, the government is actively encouraging nature-friendly methods for environmental conservation and ecosystem restoration. The nature-friendly method is specifically intended to preserve the ecosystem by allowing vegetation to live as much as possible for the living of fish and animals. Therefore, in line with these trends, there is an urgent need for development of environment-friendly and stable construction methods and various materials.

The present invention is an environmentally-friendly restoration method to replace the existing concrete retaining wall, gebion retaining wall, block type retaining wall, stonework, concrete block, gabion, etc., which have been frequently used during road cut soil slope or river embankment maintenance work. That is, it is ecological due to structural stability characteristics and vegetation spontaneity such as durability and flexure to scour. Landscape characteristics. The technical problem is the development of a completed construction method suitable for the site, such as the characteristics of construction, which is designed to contain the earth mesh (retaining wall-type or futon-type gabion) which is a feature of the present invention and the soil therein. Achievable with seed nonwoven vegetation sacks. That is, the vegetation base is made by using the nonwoven vegetation sacks of the present invention to contain the soil (석 石) generated in the field inside the wire mesh, and the seeds are attached to the nonwoven vegetation sacks, so the vegetation is early without seeding. To make it possible to In addition, due to the excellent durability and excellent flexural properties of the wire mesh, it can be installed in any section where there is concern about scouring or severe bending and irregular foundation ground, and it is structurally stable. It is easy to construct and saves construction cost because there is no need for separate filling stones by utilizing the soils generated in the field. When the method of the present invention is applied to the river bank maintenance and road cut soil slope stabilization method secures dimensional stability and ecosystem conservation. Secure hydrophilicity. It can be said that the significance is very significant because it can perform the important function of nature-friendly landscape creation.

Environmental restoration method using the seed non-woven vegetation bag of the present invention is to replace the existing concrete retaining wall, gebion retaining wall, block type retaining wall, stonework, concrete block, gabion, etc. that have been used a lot during the road cut soil slope or river embankment maintenance work As an eco-friendly restoration method, it is constructed using a wire mesh (retaining wall or duvet type gebion) and a seed non-woven vegetation bag designed to contain earth (에 石) in its interior. To describe this in detail, the wire mesh is woven into a square or hexagonal mesh of mesh 8-15CM using galvanized iron wire, or a Gabion wire mesh (10-1) or duvet iron made of diamond type galvanized EX metal wire mesh. A mesh (10-2) is used. Container bag form inside its wire mesh (10-1, 10-2). Seed nonwoven vegetation sacks (20-1, 20-2, 20-3) of the present invention made in the form of a mattress or box, and then into the nonwoven sacks (20-1, 20-2, 20-3) Form a gebion structure by embedding soil in the field, and build the foundation or river embankment of the cut slope by stacking the gebion structure step by step, or by continuously stacking the gebion structure on the bottom of the slope horizontally. It is constructed in the form of a structure to stabilize the slopes of cut soils and river banks.

In the stacking method, various applications are possible depending on the site conditions. For example, first, as shown in FIG. 1, the width of the river is inevitably to be formed in a sudden dike slope of 1: 0.3-0.5 or road cut slope. In the case of the retaining wall-type gebion wire mesh 10-1 of Figure 4, the container-shaped seed nonwoven vegetation sacks (20-1) after filling the soil (발생한 石) generated in the field by filling the retaining wall type gebion structure It can be formed by forming a layer and the gebion structure by cascading the layered layer stacked up.

Second, as illustrated in FIG. 2, the width of the river is wide and the levee slopes of the middle and middle sections are gently formed at 1: 1.5-2.0 or in the case of the road fill slope, the interior of the duvet wire mesh 10-2 of FIG. Insert a mattress-type nonwoven vegetation sachet (20-2) or two box-shaped nonwoven vegetation sacks (20-3) and fill the nonwoven vegetation sachets with soil from the field to make the gabion mattress structure. The gebion mattress structure can be formed by spreading horizontally and horizontally on the bottom of the road slope and river bank slope.

Third, as shown in FIG. 3, a non-woven vegetation sachet 20-1 attached to the inside of the wire mesh 10-1 is filled, and then the soil is generated from the field to form a gebion structure. After stacking in steps of 1 to 2 in height, the grid block 100 of FIG. 10 is installed on the bottom surface of the upper surface of the gabion structure, and the grid is filled with soil on the cap-type nonwoven vegetation sack 30-1 of FIG. 8. It can form by inserting into the empty space in (100). Cap-type seed nonwoven vegetation sack (30-1) is used as a filling material of the empty space of the grid block 100 to promote the eating habits and prevent the loss of soil. After filling the soil in the bag-shaped nonwoven vegetation sack (30-2) of Fig. 9 by forming in a continuous manner in the transverse direction at the top end of the embankment slope and the top end slope of the road embankment bank or the soil of the road Do not lose it.

In the above stacking method, not only the above-mentioned retaining wall type gabion mesh (10-1) and duvet type mesh (10-2) but also easily changeable wooden frame, steel frame, etc. can be used, the seed of the present invention If the above-described composition method is maintained after the attached nonwoven vegetation sacks 20-1, 20-2, 20-3 are naturally within the claims.

When filling non-woven vegetation bags (20-1, 20-2, 20-3) with the surrounding soil, compact compactors, etc., should be sufficiently filled. It is possible to selectively fill the mandrel instead of soil in the high water pressure section or the constant flooding section on the rear surface in consideration of the structural stability of the site.
