Description

Technology Field

[0001] The present invention relates to a vegetation ton bag used for maintenance of cut slopes or river embankments. More specifically, a shade net woven from film yarn and monofilament yarn is placed on the outer side of a seed sheet to facilitate the rooting of plant seeds, and an outwardly extended wing is attached to the bottom so that interlocking between the vegetation ton bags and between the ton bags and the slope soil body can be achieved to stably maintain the vegetation ton bags arranged along the left and right directions and constructed in multiple layers. Background Technology

[0003] Generally, vegetation soil bags or vegetation ton bags are used when maintaining cut slopes or river embankments. Patent documents 1 to 5, etc., are disclosed as prior art related to the present invention.

[0004] Patent Document 1 describes a method for constructing a foundation for a cut and fill slope or a river embankment by installing a jute (coconut) vegetation bag with seeds attached inside a reinforcing formwork such as a gabion wire mesh, a mattress-type wire mesh, a wooden frame, a steel frame, or a concrete formwork, filling it with soil and rocks from the site to form a unit structure, and then stacking this unit structure in a stepped manner or spreading it horizontally and continuously on the bottom of the river embankment slope.

[0005] Patent Document 2 relates to an eco-friendly vegetation soil bag basket with a new structure that is easy to construct while effectively preventing the loss of soil stored inside, and a method of constructing the same. A soil bag filled with soil is placed at the front inside a metal basket, and soil is filled at the rear. Then, the end of the soil bag covers the top of the soil filled inside the metal basket, and the top surface of the metal basket is blocked using a top plate, thereby preventing the soil filled in the metal basket from leaking out.

[0006] Patent Document 3 describes a structure in which soil is filled into ton bags and stacked to prevent soil loss on slopes during various civil engineering works, thereby stabilizing the slope and inducing plant growth. The rear surface in contact with the slope and the front surface exposed to the outside are made of mesh fabric, and between the front and rear surfaces, a seed sheet with seeds attached to paper or biodegradable fabric is inserted. The remaining left and right sides and the bottom surface are made of general synthetic resin burlap fabric.

[0007] Patent Document 4 discloses a vegetation soil bag fixing device comprising: a soil bag portion filled with soil inside; an anchor portion installed on the ground located on the back surface of the soil bag portion; and a connecting portion connecting the soil bag portion and the anchor portion, so as to be able to improve the pull-out resistance of the soil bag portion without installing a separate reinforcing material such as a geogrid.

[0008] Patent Document 5 aims to provide a greening structure using a greening soil bag of a novel configuration that allows for the efficient creation of a greening structure by stacking the greening soil bags in multiple layers on various greening target structures, such as retaining walls or slopes.

[0010] Meanwhile, the vegetation soil bag or vegetation ton bag according to the aforementioned conventional technology had a problem in that the seed sheet with seeds attached was placed inside the fine mesh forming the side of the ton bag, and due to this mesh, the sprouts and roots could not properly take root after the seeds germinated.

[0011] In addition, conventional vegetation soil bags or vegetation ton bags had the problem of requiring significant work time, as well as considerable cost and labor for procuring and installing these auxiliary materials, because they required the installation of separate anchors, frames, and reinforcing materials, or the use of binding members to connect adjacent soil bags, in order to interlock adjacent bags left and right or up and down, or to secure contact and support with the soil body. Prior art literature

[0013] Korean Published Patent No. 10-2006-0108595 (Oct. 18, 2006) Korean Registered Patent No. 10-1665563 (Oct. 06, 2016) Korean Published Utility Model No. 20-2018-0001997 (July 3, 2018) Korean Published Patent No. 10-2019-0082481 (July 10, 2019) Korean Registered Patent No. 0-2542373 (June 7, 2023) The problem to be solved

[0014] The present invention was devised to solve the aforementioned problems. The objective of the present invention is to solve the problem where sprouts cannot extend outward after seed germination, and roots cannot properly take root in the soil filled inside the soil bag or ton bag. Conventional vegetation soil bags or vegetation ton bags require the construction of separate anchors, frames, and reinforcing materials, which takes a long time to work and requires significant costs and labor for the provision and construction of these auxiliary materials. Therefore, the invention aims to provide a vegetation ton bag having an improved structure that allows for the stable construction of vegetation ton bags in a continuous left-right and multi-tiered up-down manner without the use of separate auxiliary materials. means of solving the problem

[0016] To achieve the above-mentioned purpose, the present invention relates to a vegetation ton bag comprising a bottom, a side, and an open top opening, wherein the opening is configured to be closed by a rope fitted around the upper perimeter of the side, and aggregate or soil is filled inside through the opening to be continuously arranged in the width direction or constructed in multiple stages during the maintenance of cut slopes or river embankments;

[0017] The above vegetation ton bag provides a vegetation ton bag in which a seed sheet is placed between two layers of paper or biodegradable fabric and attached so that seeds can germinate and sprouts can grow outward, and a shade net woven by knotting film yarn into monofilament is placed on the outside of the seed sheet and the outer edge is sewn.

[0018] Preferably, outwardly extending wings are attached to the bottom of the vegetation ton bag at the portion where the bottom of an adjacent ton bag is laid and at the portion in contact with the soil mass on the rear side, so that adjacent ton bags on the left and right are sequentially interlocked by the extending wings, and the extending wings are embedded in the soil mass of the cut slope or river embankment at the rear of the vegetation ton bag to support the vegetation ton bag. Effects of the invention

[0020] According to the present invention, the outer surface of the seed sheet is made of a shade net that facilitates the sprouts from germination to extend outward, thereby enabling vigorous plant establishment. Furthermore, the shade net blocks excessive sunlight and prevents moisture evaporation, thereby substantially improving the vegetation effect. Additionally, the vegetation ton bags allow adjacent ones on the left and right sides to have wings extending outward from the bottom that come into contact with the bottoms of adjacent vegetation ton bags, thereby maintaining a stable constructed state. Moreover, since the rear of the vegetation ton bags has wings extending outward from the bottom that are embedded in the soil of the slope, it can exert support even when constructed in multiple layers. Consequently, the constructed state can be maintained firmly without collapsing, without the need for separate reinforcing materials or support frames, which would otherwise require time and labor for cumbersome installation.

Specific details for implementing the invention

[0023] Hereinafter, preferred embodiments of the present invention that do not limit the invention will be described in detail with reference to the attached drawings.

[0024] FIGS. 1 to 6 illustrate a vegetation ton bag according to one embodiment of the present invention.

[0025] As can be seen from the attached drawings, the vegetation ton bag according to the present embodiment comprises a bottom (10), a side (20), and an open top opening (30), wherein the opening (30) is configured to be closed by a rope (40) fitted around the upper perimeter of the side (20), and aggregate or soil is filled inside through the opening (30) so as to be continuously arranged in the width direction or constructed in multiple stages when maintaining a cut slope or a river embankment;

[0026] The above vegetation ton bag (1) is structured such that a seed sheet (50) is placed on the outer side (20) which is made of mesh so that seeds can germinate and sprouts can grow outward, with seeds (54) placed between two layers of paper (52), and a shade net (60) woven by knotting film yarn (F) into monofilament yarn (M) is placed on the outside of the seed sheet (50) and sewn to the outer side (20).

[0028] In this embodiment, the outer surface of the seed sheet (50) is made of a shade net (60) that facilitates the growth of the plant (P) after germination, thereby providing the advantage of vigorous growth of the plant. This is because the weaving structure of the shade net (60) is woven by tying the weft film yarn (F) with the warp monofilament yarn (M) as shown in FIG. 3, so the gap between the weft film yarns (F) opens easily, allowing the leaves or sprouts of the plant (P) to grow outward through the gap. Furthermore, the film yarn (F) does not damage the sprout or stem despite friction with the sprout or stem. This solves the problem that in conventional technology such as Patent Document 3, the seed mat is located inside a dense and tough mesh, which prevents the sprout from growing outward properly or causes the sprout to be cut by the mesh, making growth impossible.

[0030] In addition, the shade net (60) placed outside the seed sheet (50) can block excessive sunlight and prevent moisture evaporation, thereby creating an environment suitable for seed germination and substantially improving the vegetation effect. Furthermore, the vegetation ton bag (1) can maintain a stable constructed state by having the extension wings (70) extending outward from the bottom (10) of adjacent vegetation ton bags (1) press against the bottom (10) of adjacent vegetation ton bags (1). Additionally, since the extension wings (80) extending outward from the bottom (10) of the vegetation ton bag (1) are embedded in the soil of the slope, the support force can be exerted even when constructed in multiple stages. Therefore, there are useful effects such as the construction state not collapsing and being maintained firmly without the need for separate reinforcing materials or support frames, or the cumbersome installation requiring time and labor.

[0031] Meanwhile, an eyelet (82) for inserting a fixing pack (90) is formed on the extension wing (80) attached to the rear of the above vegetation ton bag (1).

[0033] The material of the extension wings (70, 80) can be general mesh or burlap fabric, such as the side or bottom of a ton bag, and the material or size of the extension wings (70, 80) can be designed and applied with various materials and specifications to suit the application environment of the vegetation ton bag without any special restrictions.

[0035] In the drawing, symbol B is a reinforcing belt sewn at regular intervals on the bottom (10) and side to maintain the shape of the vegetation ton bag and to prevent the problem of the vegetation ton bag tearing due to the tensile force received when lifting the vegetation ton bag.

[0037] In this embodiment, the front and rear sides of the vegetation ton bag (1) are made of mesh fabric, and a seed sheet (50) and a shade net (60) are additionally sewn onto the outer side of the sides (20), while the remaining left and right sides of the vegetation ton bag are made only of mesh fabric. This is intended to allow the front and rear sides to be selectively used as outer surfaces, i.e., exposed surfaces. Of course, when constructing a wall surface using only vegetation ton bags rather than a cut slope or embankment, it is possible to use them so that plant seeds germinate and vegetation can grow on both the front and rear sides.

[0039] The process of constructing a cut slope or embankment using the vegetation ton bag of the present embodiment configured as described above is as follows.

[0040] First, using an excavator, the vegetation ton bag (1) is unfolded, and the ropes (40) exposed at the four upper corners are hooked onto the hooks. Then, the vegetation ton bag is filled with soil using the excavator bucket. After that, the rope (40) attached to the outer edge of the upper opening (30) of the vegetation ton bag (1) is pulled to close the upper opening (30), and the excavator arm is operated to move it to the cut slope or embankment side for construction.

[0041] When constructing the vegetation ton bag, as shown in FIGS. 4 and 5, one of the two sides (20) where the seed sheet (50) is located should face outward, and the other side should be in contact with the soil side of the cut slope or embankment.

[0042] The construction sequence can be carried out sequentially from one side to the other. The extension wing (80) attached to the outer side of the bottom (10) is unfolded to cover the vegetation ton bag with soil, and the extension wing (70) extended to the other side is unfolded, and the adjacent vegetation ton bag (1) is filled with soil and placed on top. By repeating this process in the left and right directions, the vegetation ton bags adjacent in the left and right directions are interlocked by the close contact between the extension wing (70) and the bottom (10), so that even if an external force is applied while they are aligned, they do not become disorganized.

[0043] Meanwhile, when constructing a cut slope or embankment in multiple stages, as shown in Fig. 6, the vegetation ton bag (1) can be constructed sequentially in stages, such as 2 and 3, with a predetermined distance of setback from the top of the lowest layer. In this case, the extension wing (80) is spread out on the rear soil body, and a fixing pack (90) is driven into the eyelet (82). Then, the rear soil body (G) is compacted on top of it, thereby allowing the vegetation ton bag (1) to be stably supported on the rear soil body. Additionally, the extension wing (70) attached to the side is spread out sequentially so that adjacent vegetation ton bags (1) are interlocked, and the vegetation ton bag (1) is placed on top of it, thereby allowing the vegetation ton bag (1) to maintain a stably aligned state.

[0045] As explained above, the vegetation ton bag according to the present invention has the advantage of being able to maintain a sturdy structure without collapse, as the outer surface of the seed sheet is covered with a shade net that facilitates the sprouts from germination to extend outward, thereby allowing for vigorous plant establishment, and the shade net prevents excessive sunlight and moisture evaporation, thereby improving the vegetation effect. Furthermore, the vegetation ton bag allows adjacent ton bags to maintain a stable structure by having wings extending outward from the bottom contact the bottoms of adjacent vegetation ton bags, and the rear of the vegetation ton bag is embedded in the soil of the slope by having wings extending outward from the bottom, so that it can exert support even when constructed in multiple stages.
