Abstract

PURPOSE: To avoid the deterioration of a natural landscape by concrete by beautifying execution having excellent quality feeling when a slope, etc., facing a mountainous road are reinforced by a method of frame construction. CONSTITUTION: Colored nets 5 are stuck on the exposed surfaces of the concrete frames 3 for reinforcement of the face of a slope 1 formed by a method of frame construction. Ivies are vegetated in the layers 4A of earth brought from another place and mixed in the soil in reinforcing frames 2, and the ivies are entwined with the colored nets 5. The colors of other trees and plants 6 vegetated in the layers 4A of earth brought from another place and mixed in the soil and the colored nets 5 or the green of the ivies naturally merge in, and a landscape on the reinforced face of the slope 1 harmonizes with peripheral environment. When the colored nets 5 are stuck continuously onto the concrete frames 3 forming straight lines among the adjacent reinforcing frames in the reinforcing frames 3 in the execution of works, the workability of the sticking is improved remarkably.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beautification method of a legal frame,
Specifically, it relates to a method of improving the landscape of the inclined surface by subjecting the exposed surface of the concrete frame formed by the frame construction method to a colored treatment with a sense of thickness and harmonizing the color with the plants and trees planted in the reinforcing frame. is there.

[0002]

2. Description of the Related Art Slope reinforcement work is often performed to prevent the collapse of the ground on the slope in order to ensure the safety of traffic when the slope is close to a road on a mountain road.
Various methods are adopted for the reinforcement, and as one of them, it is known to widely cover the inclined surface with a net for preventing the pebbles from sliding down. In some cases, vegetation mats may be placed under the net to promote greening. On the other hand, when the concrete is reinforced, the effect of reinforcing the slope is increased, but the concrete on which the wall surface or the frame surface is formed is exposed, and the surface is easily visible to passersby. In that case, gray concrete does not fit in well with the surrounding green, and the landscape is often spoiled.

[0003]

Recently, green processing is sometimes performed for the purpose of maintaining the scenery and reducing the feeling of pressure on passersby. For example, when the slope is reinforced by spraying concrete, green paint is applied to one side. Such color coating achieves simple greening, but gives a strong sense of being an artificial object, and also causes a feeling of discomfort that lacks harmony with the surrounding environment. Furthermore, over time, the paint may react with the alkali content of concrete, fade due to the influence of ultraviolet rays, or the paint may partially flow due to wind and rain, which may cause a deterioration in aesthetics.

By the way, a concrete frame is often formed by a frame construction method such as a core frame construction method to reinforce the slope. This has the advantage that the slope can be suppressed by the concrete reinforcement frame and that the vegetation for vegetation planted in a large number of frames can be stabilized. That is, the structure is such that the vertical and horizontal reinforcing frames are provided on the slope, and the soil is applied to each of the reinforcing frames, and the soil layer is planted to prevent landslides. Even in this case, the concrete will be exposed on the slope with a geometric pattern such as a lattice,
The gray concrete frame divides the planting area into several sections, which appears in a blatant manner and makes the landscape inferior. Of course, it is possible to add color to the concrete, but it goes without saying that the greening with a paint is flat and cannot recall a soft texture.

Even if vegetation is planted in the soil layer after forming the framework as described above, planting has not grown for a while after the completion of the slope construction and the landscape It takes time to settle down, and during that time it gives the impression of a barren area. At that time, if concrete is exposed or artificial color due to paint is conspicuous, it will not be in harmony with the surroundings, and it will give an impression of the destruction of the natural environment to passersby and give the driver a sense of instability. .

The present invention has been made in view of the above problems, and an object thereof is to alleviate the occurrence of discomfort and the obstruction of the landscape caused by the concrete on the slope where the reinforcing frame of concrete is formed by using the frame construction method. That is, it is possible to use a framework structure that gives a soft impression with a texture even when artificially greening, to improve the workability of greening work or beautification work on the reinforcement frame, and artificial beautification of the concrete frame. It is to provide a beautification method of a legal framework that realizes that planted plants can easily be transformed into natural beauty even after the treatment.

[0007]

The present invention is applied to a beautification method for a concrete-reinforced slope. The feature is that, with reference to FIG. 1, a colored net 5 is attached to an exposed surface of a concrete frame 3 which forms a reinforcing frame 2 of a slope 1 formed by a frame construction method.

A colored net 5 may be continuously attached to a concrete frame 3 which is a straight line between adjacent reinforcing frames of the reinforcing frame 2.

A colored net 5 is attached to an exposed surface of a concrete frame 3 which forms a reinforcing frame 2 of a slope 1 formed by a frame construction method, and further, as shown in FIG. That is, the ivy 9 was planted in the upper part of each horizontal frame 3B in 4A and in the vicinity of the vertical frame 3A.

[0010]

When the slope 1 is reinforced by the frame construction method, the colored net 5 having a natural color such as green or brown is attached to the concrete frame 3. The exposed surface of the concrete frame 3 is covered with the colored net 5, and the appearance of the reinforced slope 1 is improved.

A colored net 5 manufactured or cut into a long dimension is continuously attached to a concrete frame 3 which is straight between adjacent reinforcing frames. Vertical frame 3 with many
Construction efficiency for A etc. is improved.

When the colored net 5 having a natural color such as green or brown is attached to the concrete frame 3, the vegetation mat containing ivy seeds is used to form the lateral frames 3 in the soil layer 4A in the reinforcing frame 2.
It is installed in the upper part of B near the vertical frame 3A. Alternatively, seeds of ivy 9 are sown on the above-mentioned site after the sticking work. As it grows, the ivy 9 is entangled with the colored net 5 that covers the vertical frame 3A, and the slope 1 is covered with vegetation to maintain the natural landscape.

[0013]

EFFECTS OF THE INVENTION According to the present invention, a colored net imparts a calm and soft three-dimensional effect and texture similar to the overgrowth of vegetation to the concrete reinforcing frame formed by the frame construction method, and vegetation is carried out in the soil layer. A slope that matches the greenery of the vegetation that was created can be realized, and it is possible to suppress the maintenance of the landscape and the discomfort of passersby.

If the colored nets are continuously attached to the straight concrete frames of the adjacent reinforcing frames, the efficiency of the netting work can be improved.

When vines are planted in the soil layer, the vines crawl on the colored net, and the greening of the concrete frame can be promoted. Further, a three-dimensional effect is generated more than that of the colored net, and the natural beauty is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A beautification method for a legal frame according to the present invention will be described below in detail with reference to the drawings. FIG. 2 is a perspective view in which a large number of concrete reinforcement frames 2 are formed by the frame construction method applied to the slope 1. Then, each concrete frame 3 is subjected to beautification processing described below.

The reinforcing frame 2 is formed in a lattice shape, and each concrete frame 3 has, for example, a height and a width of 30 cm, and a pitch of 120 cm, for example. Therefore, the rectangle to which the soil 4 is applied is 90 cm square. The vertical frames 3A, 3A extending vertically vertically between the adjacent reinforcing frames of the reinforcing frames 2, 2 are
As shown by the solid lines intersecting in FIG. 1, a colored net 5A that has been subjected to pile processing such as curling a part of the net
Are continuously attached.

The material of the colored net 5 is, for example, polyethylene, and thin weft threads are piled between the warp threads. As the net color, a light green or dark green color that matches the vegetation 6 or a brown color that is similar to the natural skin is used. Pile processing can give a soft three-dimensional effect and texture. If you use pilings between the weft threads, the three-dimensional effect will increase and the appearance will improve. Of course, even a net that has not been piled can exhibit a certain degree of texture that the net itself has. In any case, one that is easy to harmonize with the surrounding landscape should be adopted.

As described above, for example, when a continuous net is attached to the vertical frame 3A, each horizontal frame 3B is provided with a net 5B intermittently for each part, that is, in the horizontal direction. It is stretched as shown by the crossed dashed lines.
If you want to increase the efficiency of sticking work, concrete frame 3
However, the colored nets 5C may be covered so as to be continuous on the horizontal frames 3B and 3B extending linearly as shown in FIG. 30 cm as above
In the vertical frame 3A or the horizontal frame 3B having a square cross section, as shown in FIG. 4, for example, a colored net 5 manufactured or cut in advance to have a width of 90 cm is used.
Is covered. In the vertical frame 3A reinforced by the reinforcing bars 7, the left and right lower parts thereof (see FIG. 4A),
It is fixed with rivets 8 and the like. On the other hand, in the horizontal frame 3B, as shown in FIG. 4B, the net 5 is fixed to the base of the upper side surface on the upper side and to the base 3K connected to the lower side surface on the lower side.

After the colored net 5 is attached, as shown in FIG. 5, a vine 9 is provided near the vertical frame 3A at the upper portion of each horizontal frame 3B in the soil layer 4A in the reinforcing frame 2. It is good to vegetate. Since the sowing is performed at the portion indicated by the arrow M in FIG. 4 (b), it does not flow down, and when it grows and the vine grows, it crawls up to cover the vertical frame 3A. The ivy 9 may be evergreen or deciduous, and may be selected according to the vegetation in the reinforcement frame 2 and the surrounding landscape. In this way, when the vine 9 is made to crawl, the colored net 5 may have a brown color similar to that of the soil layer 4A. Further, the ivy 9 can also be entangled by using a net which is not subjected to the pile processing as described above. By the way, Figure 4
As indicated by a virtual line in (b), the vegetation mat 10 may be arranged under the colored net 5 on the upper surface of the horizontal frame 3B. If vine seeds are put in the vegetation mat 10, the vine vine can be made to crawl on the vertical frame 3A, and the vegetation mat 10 will not be washed away even when the surface layer of the soil changes due to wind and rain. Can be kept.

In the slope reinforcement structure having such a structure, the slope of the slope is beautified as follows. First, as shown in FIG. 2, a reinforcing frame 2 is formed on the slope 1 by the frame construction method, and anchors (not shown) are driven into the intersections of the reinforcing frame 2 at a depth of 1 m or more to press down the slope 1. To be And 5 cm to 1 inside each reinforcing frame 2.
Soil 4 is applied to about 0 cm.

After that, as shown in FIG. 1 and the like, the width is 90 cm.
The colored net 5 is covered from the top to the bottom of the vertical frame 3A.
The left and right sides of the colored net 5 are folded into the left and right side surfaces of the vertical frame 3A (see FIG. 4A), and pilot holes are made near the base of the side surfaces of the vertical frame at intervals of 30 cm in the vertical direction.
A filler such as mortar is injected, and a rivet 8 with a washer having a length that does not interfere with the reinforcing bar 7 is driven in. Reinforcement frame 2
Since the colored net 5 cannot be folded laterally at the intersection, the horizontal frames 3B located on the left and right of the intersection.
The net protruding above is cut and removed. In addition, when the mesh of the colored net 5 is large or when the side surface of the concrete frame 3 has some irregularities, it is not shown, but it is 3 cm.
A thin metal plate of about 20 cm is used as a washer and can be pressed in a wide area.

When the drilling and the rivet driving are sequentially advanced downward, one colored net 5 is evenly attached on the vertical frame 3A. When the attaching work on some of the vertical frames 3A is completed, the colored nets 5 of 90 cm × 90 cm are put on the horizontal frames 3B, folded into the upper surface and the lower surface, and riveted by the same procedure. Before the net is folded into the upper surface, a short vegetation mat 10 (see FIG. 4 (b)) with vine seeds is laid on the upper surface of the end of the lateral frame 3B, and the vegetation mat 10 is pressed by the colored net 5. Be riveted to. Since the work of stopping the net on the lower surface is not easy, the rivet 8 is driven toward the foundation 3K.
If the long colored nets 5 are continuously stretched from left to right on the horizontal frames 3B, 3B (see FIG. 3), the pasting work can be speeded up. In that case as well, the upper and lower protruding portions at the intersecting portions of the reinforcing frame 2 are cut by scissors or the like.

In this way, the concrete reinforcing frame 2 is covered with the colored net 5 such as green or brown, but the colored net 5 gives a three-dimensional effect to the flat surface of the concrete frame 3 and is more calm than paint. It has a soft, textured appearance and is easy to blend in with the surrounding environment.
As the vegetation sown in the soil layer 4A grows, the area of the reinforced slope 1 presents a natural landscape. In addition, when the vines 9 that have been planted cover most of the vertical frame 3A and part of the horizontal frame 3B,
A harmonious greenery with abundant natural beauty is achieved, and the scenery from the mountain road becomes calm and familiar with the natural environment.

In this way, if the gray or the like on the exposed surface of the concrete is covered with the colored net 5 or the vine 9, even if the surface layer of the concrete may be finely peeled off due to the passage of time, the net or the vine may It is prevented from falling off. Even when the vegetation is not growing immediately after the completion of the slope reinforcement work, the color inconsistency between the background and concrete is resolved. When brown is used as the colored net 5, the entire surface becomes a background color, and it is possible to prevent an abnormal green color from remaining in the late autumn or winter wither season.

Incidentally, the frame construction method includes a free frame construction method, a core frame construction method, a haunch frame construction method and the like, but the present invention can be applied to a reinforcing form in which a concrete frame is exposed on the slope. At that time, even if the reinforcing frame is not in the grid shape as described above, greening and beautification of the slope can be realized by attaching the colored net. Colored nets are generally made of synthetic fibers such as polyethylene, but when creeping vines, a natural fiber net of cotton or hemp or a biodegradable plastic net that is decomposed by bacteria may be used. For example, even if the net disappears when the vines are overgrown, the greening is maintained, and after that, the impression of artificial treatment is significantly reduced.

As can be seen from the above description, the beautification method of the law frame according to the present invention can be applied not only to the sloped land near the road but also to the slope ground reinforcement of the dam.
Even if the top surface of the concrete frame is large, such as 60 cm to 70 cm, and the grid pitch is 180 cm or more, the colored net may be cut in advance to fit the area to be attached. In addition, the existing reinforcement slope can be easily applied not only when the plants and grasses in the soil layer are in a dead state but also when they are in a certain amount of growth. And the natural beauty of the reinforced slope with a three-dimensional effect is brought out.
