Description

retaining wall structure

The present invention relates to a retaining wall structure, and more specifically, to a retaining wall structure that greatly reduces the time required to construct a retaining wall and increases construction convenience by easily fixing each earth bag forming the retaining wall to the geometry.

In general, a retaining wall refers to a structure installed to prevent soil loss and ensure its solidity and stability in areas where soil collapse occurs easily due to soil pressure, such as the side of a road or the foot of a mountain. .

Currently, there are many different installation methods and types of retaining walls, and the most traditional method is to install a steel mesh on the construction point and then inject mixed concrete to solidify it. However, this method has the disadvantage that not only is the scale of construction very large, but the difficulty of construction is also high, and the time for the mixed concrete to solidify is relatively long, so the construction period is inevitably longer.

In addition, retaining wall structures made of concrete are limited in covering the soil, and are prone to being lost due to wind or water invasion, and the efficiency of environmental greening is also very low, furthermore, it is difficult to properly preserve the soil.

In order to compensate for the shortcomings of the existing retaining wall structure, the method of completing the retaining wall by stacking sacks is currently frequently used. In this method, the sacks are filled with sand/soil, etc., and then these are placed vertically. Alternatively, it is a structure that completes a retaining wall by connecting and stacking them horizontally. At this time, connecting and fixing parts are installed between adjacent bag sacks so that the bag sacks can be fixed more firmly without slipping against each other.

However, the retaining wall structure completed by connecting and fixing adjacent sacks using the above connection fixing parts does not have enough strength to withstand strong rain and wind, and the wall is easily damaged under harsh environments such as sand winds such as yellow dust. I discovered that this problem occurs.

In addition, there are many cases where retaining walls are built using items called tonang filled with sand or soil. For example, as shown in Figures 1 and 2, several tonbags (1) are arranged horizontally and placed on top of them. In many cases, retaining walls are formed by stacking soil bags.

Tonacs used conventionally are made in a form that has either a longer horizontal or vertical length and a predetermined thickness. As shown in Figures 1 and 2, the tonbags are adjacent so that the vertical sides that are longer than the horizontal sides touch each other. They are placed neatly, or placed adjacent to each other so that the roadsides touch each other, and retaining walls are built by stacking earthen bags on top of them.

The present invention can significantly reduce the cost of constructing a retaining wall by using a significantly smaller number of soil bags, and includes a fixed net installed on the wall, tying the soil bags to the fixed net, or attaching a fixing plate between the soil bags to the fixed net. We would like to propose a retaining wall structure that can increase the strength of the structure by tying it together.

The retaining wall structure of the embodiment includes a fixed net installed to surround at least a portion of the wall, and a plurality of geotextile materials disposed in front of the fixed net and surrounding soil particles and seeds of plants that can be germinated. It includes a binding plate disposed between the soil bags and the soil bags arranged above and below to bind the soil bags, and a binding string for coupling the binding plate to the fixing net, and the soil bag is made in the shape of a rectangular hexahedron, and includes an upper and lower surface having the largest area among the surfaces constituting the soil bag, a long-side side portion and a short-side side portion forming the side of the soil bag between the upper and lower surfaces, and the long-side side portion It has a larger area than the cross-section side portion and a smaller area than the upper and lower surfaces, and the soil bag is arranged so that the long side side portion faces the ground, and the soil bags are arranged so that the long side side portions are in contact with the ground in the vertical direction. It is configured to be stacked, and the soil bags are arranged so that the short side portions are in contact with the ground in the left and right directions.

The proposed retaining wall structure has the advantage of being able to construct a retaining wall structure that can be built firmly as a structure along with greening using earth bags in narrow spaces such as rivers.

The soil bag 10 of the embodiment is made of a durable geotextile material and a fabric that allows water to flow through the protective bag and the soil bag and allows seeds to germinate. Additionally, these protective sacs and soil bags may contain fine soil particles and plant seeds that can be germinated.

In the case of the earthen bag 10 shown in FIG. 3, it is formed in a rectangular shape with a horizontal side (A), a vertical side (B), and a height (C), with the length of the vertical side (B) being longer than the horizontal side (A). For example, the horizontal side (A) may be approximately 30 cm, the vertical side (B) may be approximately 70 cm, and the height (C) may be approximately 15 cm.

The earth bag 10 includes a ton bag body 20 forming a body, and the to bag body 20 has a shape having a long side upper surface portion 11 and a short side side portion 12. In this embodiment, the earth bag ( The side 12 of 10), that is, the side formed by the vertical side (B) and the height (C), is constructed so that it faces the ground.

That is, the ton bag body 20 of the ton bag 10 has an upper and lower surface portion 11 having the largest area among the surfaces constituting the to bag body, and a long side side portion 12 that forms the side of the to bag body between the upper and lower surfaces. and a short side portion 13.

The short-side side portion 13 has the smallest area among the surfaces constituting the ton bag body, and due to this configuration, the ton bag body as a whole has the shape of a rectangular parallelepiped. The long side side portion 12 has a larger area than the short side side portion 13 and a smaller area than the upper and lower side portions 11.

The long side side portion has a larger area than the cross-sectional side portion and a smaller area than the upper and lower surfaces.

Among the surfaces forming the soil bag 10, the widest part is arranged to face forward or backward, so that the short side portion 12 with a smaller area is constructed to face the ground or the sky.

That is, the soil bags are arranged so that the long-side side portions face the ground, and the soil bags are stacked so that the long-side side portions are in contact with the ground in the vertical direction, and the short-side side portions are in contact with the ground in the left-right direction. The soil bags are arranged so that they are in contact with each other.

However, in some cases, it may be possible to construct the structure so that the part with the smallest area, that is, the part formed by the street (A) and the height (C), faces the ground.

As described above, the soil bag 10 is made of a shape having a long-side side portion and a short-side side portion, and in particular, the soil bag 10 is stacked so that the short-side side portion faces the ground.

The retaining wall structure of the embodiment can be built in a place such as a river where there is an existing structure such as a concrete wall, and greening is easily possible.

Referring to Figures 5 and 6, a binding plate 70 is disposed between earth bags 10 arranged with short side surfaces facing the ground to suppress the flow of these earth bags. The upper protrusion protruding from the upper surface of the binding plate 70 and the lower protrusion protruding from the lower surface penetrate the soil bag, thereby suppressing the flow of the soil bag.

As shown, in the case of greening a vertically erected structure such as a concrete wall 500, a fixing net 50 surrounding at least a portion of the outer circumference of the concrete wall 500 is arranged, and a fixing net 50 is placed adjacent to the fixing net 50. Stack the soil bags so that

And, in Figures 5 and 6, a binding string 300 is used to tie the binding plate 70 and the fixing net 50, and the binding strap 300 allows the soil bags to move in the opposite direction of the concrete wall 500. It additionally serves to prevent falling. In particular, the binding string 300 can be wrapped around the earth bag 10 and then tied to the fixing net 50 instead of the binding plate 70 during construction.

An embodiment of binding the soil bag 10 to the fixing net 50 using the binding string 300 is shown in FIG. 9 .

The binding string 300 can be used by cutting the existing geogrid used during retaining wall construction into small pieces, and in this case, there is an advantage of being able to use the geogrid remaining at the construction site. In addition, the binding string 300 of the embodiment may use various materials such as nylon string or non-woven fabric, and it may also be possible to use members left over from the construction site.

Meanwhile, when tying the binding plate 70 and the fixing net 50 using the binding string 300, one side of the binding plate 70 is attached so that the binding string 300 is firmly coupled to the binding plate 70. A string hook 73 may be formed.

Referring to Figures 7 and 8, the binding plate 70 of the embodiment is made of a rectangular shape, and an upper protrusion 71 protruding upward is formed on the upper surface, and a lower protrusion 72 protruding downward is formed on the lower surface. is formed. In addition, a strap hook 73 is formed to protrude from the upper surface of the binding plate 70 by a predetermined thickness to ensure that the binding strap 70 is firmly attached or fastened.

The string hook 73 may be shaped like a “T” or shaped like an arrow (FIG. 9). In addition, it may be implemented in various shapes, and the string hook 73 includes a vertical portion extending in a vertical direction from the upper surface of the binding plate 70, and a head extending in a horizontal direction from the end of the vertical portion. It may be made of parts, and if the head part extends horizontally, the string hook may be formed in a "T" shape, and if the head part is formed to be inclined downward, it may be formed in an arrow shape as shown in FIG. 9. The head portion may be formed to be gently bent downward.

By using the binding plate 70 on which such a string hook 73 is formed, it becomes easy to tie to the binding plate 70 using the binding string 300, and the binding string 300 is connected to the fixing net 500. If tied, a firm bond can be achieved between the binding plate and the fixing net, and further between the soil bags and the fixing net.

Referring to FIG. 9, when greening one side of the concrete wall 500 as in the previously described embodiment, a fixing net 50 covering at least a portion of the concrete wall 500 is installed, and the fixing net 50 is installed. To fix to the concrete wall (500), a fixing stake (201) and a U-shaped fixing pin (202) are used.

Then, the soil bags 10 arranged in the upper and lower layers are bound together using the binding plate 70, and the binding straps 300 are used to surround the soil bags 10 and then fix the binding straps 300. It is tied to the net (50).

That is, while stacking each soil bag 10, each soil bag is surrounded using a binding string 300, and then the binding string 300 is tied to the fixing net 50, so that the soil bag and the fixing net 50 ) to ensure that the bond between them is achieved.

A retaining wall structure can be built in the same process as a tactical bar, and construction is easily accomplished by connecting each soil bag to the fixing net, and the upper and lower soil bags are also connected by connecting plates, making it easier to build a sturdy retaining wall. You can do it.

The present invention can be implemented as a retaining wall structure to prevent soil loss and ensure its solidity and stability in areas where soil collapse occurs easily due to soil pressure, such as on the side of a road or at the foot of a mountain. There is potential for industrial use.
