The present invention relates to a vegetation reinforced soil construction method and a vegetation reinforced soil construction structure constructed by the method, and more specifically, all sections are sufficiently compacted without being limited to the slope because the construction is performed with the scaffold and the formwork on the front surface. The present invention relates to a vegetation reinforced soil construction method and a vegetation reinforced soil construction structure constructed by this method to enable a more stable structure.

Retaining wall refers to a wall structure that resists earth pressure and prevents soil from falling down. It is an anti-earth pressure structure that maintains stability by using the weight of the wall itself and the frictional force of the floor surface.It is based on the earth pressure acting on the wall, the load on the soil, the support force, the support force of the ground, etc. It is designed to ensure stability against falling or slipping of the whole.

Retaining wall types are classified into gravity type, anti-gravity type and inverted type T and L type, subwall type retaining wall and special retaining wall depending on the structure.

Gravity type is mainly in the form of maintaining the stability of the retaining wall itself. It is generally stacked with concrete and is used for small retaining walls with a height of 3 to 4m or less. The antigravity type is the intermediate type between gravity type, inverse T type, and L type, and it uses reinforced concrete with very low rebar. Inverted T-type and L-type consist of vertical wall and base plate and use reinforced concrete and are usually used for medium retaining walls of about 3 ~ 7m. The subwall retaining wall is a subwall (secondary wall or support wall) formed on an L-shaped retaining wall, and is generally used for retaining walls of about 6 to 7 m or more. Stone wall or block wall retaining wall is a stack of stones or blocks, so it is easy to construct and has been widely used since ancient times. Other special types include shelf retaining walls, shelf-supported retaining walls, box retaining walls, board pile retaining walls, tettle retaining walls, and retaining walls according to reinforced earthwork.

Among these retaining walls, the rubble retaining wall, which is a slope protection method that resists earth pressure with its own weight, is piled up step by step by placing rubble on the iron wire of the faceted square, and the reinforcement soil blocks are piled on the front side, and the floor is laid by grids and soil on the back. Therefore, the reinforcement earth retaining wall which resists earth pressure, and the concrete structure are formed to form a structure which resists earth pressure.

Such conventional concrete retaining wall, reinforced earth retaining wall, stonework and the like are structurally stable as rigid. However, it is not environmentally friendly because vegetation (growing of grass or trees) is impossible on the retaining wall.

In addition, the construction period is long and the material cost is high. In addition, in the existing reinforcement method, the slope is limited because the work is carried out without placing scaffolding and formwork on the front side. In addition, since the reinforcing material is laid on the flat surface, and the non-woven fabric is installed on the front side, the anchor is pinned to install the net, and the vegetation material is administered or the vegetation soil layer is wrapped with the non-woven fabric. It shows the disadvantage. In addition, since the tensile stress is weak after the construction of the front part and sags at the end surface of the fill layer, there is a defect that the sufficient compaction is not made.

An object of the present invention, because the construction of the scaffold and formwork on the front part is not limited to the slope, all the sections can be compacted enough to show a more stable structure and construction method of the vegetation-reinforced soil and the construction by this method It is to provide the structure of vegetation reinforcement soil.

Another object of the present invention is to provide a vegetation-reinforced soil construction method and the vegetation-reinforced soil construction structure constructed by this method to be able to exert an effective tensile stress by integrally connecting the wire and the reinforcement materials to integrate the entire fill layer.

Another object of the present invention is to connect the wire and reinforcing material directly, and put the vegetation mat between the construction work, reducing the labor hassle and material consumption, and prevent earth and sand loss, environmentally friendly to harmonize with the surrounding environment It is to provide a vegetation reinforced soil construction method and a vegetation reinforced soil construction structure constructed by the method.

The above object is a first step of supporting and installing a scaffold and formwork with a scaffold fixing pin on a base plate on which a predetermined drain hole and a drain line are constructed; A second step of installing a net and vegetation mat on the back side of the supported scaffold and formwork; Forming a fill layer on the ground, and then arranging the reinforcement thereon, connecting the end of the reinforcement adjacent to the net with the net, and then slicing the fill layer evenly; A fourth step of fixing the scaffold and the formwork with the scaffold fixing pins on the front surface of the fill layer so as not to cause deformation in compaction while repeatedly performing the third step according to the height of the fill to be constructed; After completion of the fill body of the desired height, the fifth step of dismantling the scaffold and formwork; is achieved by a vegetation-reinforced soil construction method comprising a.

Here, the end of the reinforcing material adjacent to the net side is bent in a b-shape, it is preferably connected to the net by the wire.

The reinforcement used in the fourth step may be integrally connected to the net by the first reinforcement and the iron wire in the third step. However, it does not necessarily need to be integrated.

On the other hand, the above object is also achieved by the vegetation-reinforced soil construction structure constructed by the above-described construction method.

The vegetation plate may further include a vegetation member having an inclined rib extending obliquely upwardly from the plate surface of the vegetation plate to form a penetrating portion therebetween and disposed on the front portion to assist vegetation.

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

1 is a view showing a vegetation reinforcement soil construction method according to a first embodiment of the present invention, Figure 2 is a view showing the vegetation reinforcement soil construction structure constructed by the method of Figure 1, Figure 3 shows a connection state of the reinforcement and the network Figure 4 is a complete view of Figure 2 made with vegetation.

Referring to these drawings, the vegetation reinforced soil construction method according to the first embodiment of the present invention goes through the following steps.

First, the scaffold 14 and the formwork 16 are arranged on the basis of a predetermined slope required on the base plate on which the predetermined drain port 10 and the drain line 12 are constructed. At this time, formwork 16 is placed inside and scaffold 14 is placed outside.

Here, the scaffold 14 is arranged to make a slope on the required surface and to support the form 16. Formwork (16) is the same for the entire fill layer (1a, 1b, 1c ...) is to support without rolling and is used for the purpose of making the surface constant and smooth. Then, the scaffold 14 and the formwork 16 are fixed by using a separate scaffold fixing pin 18. Since the scaffold 14 and the formwork 16 are arranged in this way, there is an advantage that the construction can be easily performed without being limited to the inclination.

Subsequently, the net 20 and the vegetation mat 22 are disposed on the back of the scaffold 14 and the formwork 16. Then, the first fill layer 1a is formed from the ground, and then the reinforcing material 30a is disposed thereon. The reinforcing material (30a) may be used, such as grid, geotextile reinforcing materials such as geotextiles and corrosion-resistant wire, wire mesh, etc., even after construction is embedded in the fill layer (1a).

At this time, if the reinforcing material (30a) is separated from the net 20, when the compaction layer (1a) of the reinforcing material (30a) may be separated. To prevent this, the ends of the reinforcement 30a adjacent to the net 20 side are bent constantly. At this time, the end of the reinforcing material is bent in a nearly Hangul "b" shape, after being bent to connect the bent end and the net 20 by the iron wire 24 (see Fig. 3). At this time, the iron wire 24 is integrated with the reinforcing material (30a) in the coating or plating to prevent corrosion to achieve structural stability.

Then, the first fill layer 1a is evenly ground. Thus, after placing the reinforcing material (30a) on the first fill layer (1a) from the ground and connected to the net 20, the chopped drawing is shown in Figure 1 (a).

When the first fill layer 1a is completed, the second fill layer 1b is formed thereon, as shown in FIG. At this time, after supporting the scaffold fixing pin 18 at the corresponding position, the second reinforcement (30b) is placed and fixed to the mesh 20 using the iron wire 24, the second fill layer (1b) Will be prepared. When connecting with the wire 24, it may be integrally connected to the net 20 together with the end of the first reinforcing material (30a).

When the second fill layer 1b is completed as shown in (b) of FIG. 1, the scaffold fixing pin 18 is supported at the corresponding position as shown in FIG. ), And fixed to the net 20 using the iron wire 24, and then by the compacting to form a third fill layer (1c) as shown in Fig. 1 (c).

Forming the fill layer (1a, 1b, 1c ...) in accordance with the fill height (H) to be constructed in this way, the structure of the fill body (1) as shown in Figure 2 is completed. Then, when the scaffold 14 and the formwork 16 are dismantled, a structure as shown in FIG. 4 can be obtained. 4 is a view showing a state in which the vegetation is made to the front in the state in which the scaffold 14 and the formwork 16 are dismantled.

On the other hand, Figure 5 is an enlarged view of the main portion of the vegetation reinforced soil construction structure according to a second embodiment of the present invention, Figure 6 is a front view of the vegetation member used in FIG.

As shown in these figures, a separate vegetation member 40 for vegetation may be further disposed on the front surface of the fill body (1). The vegetation member 40 has a flat plate-like vegetation plate 41 and an inclined rib 42 extending obliquely upward from the plate surface of the vegetation plate 41 to form a through portion 40a therebetween.

Thus, as shown in FIG. 5, when the vegetation member 40 is disposed on the front surface of the fill body 1, the soils of the fill layer 1a, 1b, 1c... Are penetrated through the vegetation member 40. It may be filled to the end of the inclined rib 42 through the. Thus, as in the enlarged portion of FIG. 5, it is advantageous to have vegetation.

According to the present invention, since the scaffold 14 and the formwork 16 are mounted on the front part, all sections can be sufficiently compacted without being limited to inclination, thereby showing a more stable structure.

In addition, by connecting the wire 24 and the reinforcing materials (30a, 30b, 30c ...) integrally, it is possible to exhibit an effective tensile stress by integrating the entire fill layer (1a, 1b, 1c ...). In addition, since the wire 24 and the reinforcing materials (30a, 30b, 30c ...) are directly connected and the vegetation mat (22) is inserted between them, it is possible to reduce the trouble of work and material consumption and to prevent earth and sand loss. Afterwards, the vegetation will be possible in the future and will be able to complete eco-friendly fillets (1) that can be harmonized with the surrounding environment.

By installing reinforcing materials (30a, 30b, 30c ...) inside the earthen body (1) in civil engineering work, it restrains the tensile strain of soil according to the frictional resistance generated between the earthen body (1) and prevents shear sliding destruction. The reinforcing effect of the ground can be obtained. In addition, there is an advantage that the construction speed is fast and the material is easy to carry and low price.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

In the above-described embodiment, the description thereof is omitted, but a drainage channel may be formed at the bottom of the fill section by rubble and blind culvert, and the drainage membrane may be formed on the back of the fill body by non-woven fabric or rubble.

In addition to the above-described embodiment, instead of the vegetation mat, the seed may be sprayed like seed spray to make the vegetation soil. In this case the formwork may not be used.

Although the description is omitted in the above-described embodiment, the vegetation mat contains seeds, and one of the vegetation mats may be selectively used in the form of plate, mat, block, and bag for the purpose of preventing vegetation and soil loss. .

Although the description is omitted in the above embodiment, in order to arrange the reinforcement on the cut surface, the reinforcement may be separately supported by driving an anchor or the like into a region where the reinforcement is disposed.
