Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a civil engineering landscape, and more particularly to a technique for reducing the functionality of a functional structure or the like located near a landscaped surface while maintaining a landscape effect. It does not relate to the method of forming a scenic surface.

[0002]

BACKGROUND OF THE INVENTION For example, when a slope is formed on the side of a road due to construction of a road, it is not preferable to leave the slope with an open cut in view of the scenery and safety.
Therefore, on this type of slopes, scenic works are carried out to prevent landslides by planting vegetation, but the vegetation at the bottom of the slope and the weeds that have settled here are located below the slope as they grow. This causes the functional structure to be degraded.

Specifically, when the functional structure is a road, as shown in FIG. 6 (b), the vegetation approaches a position close to the road or covers the road. In order to avoid traffic accidents, pedestrians run off the lane, and vehicles run off the oncoming lane, thereby compromising traffic safety. In addition, when the functional structure is a gutter, falling leaves, dead branches, and the like clog the inside of the groove, obstructing the water flow, and in extreme cases, rainwater, etc., which overflows on the road may threaten traffic safety. Situations occur. In addition to the slope, the same problem occurs when vegetation is applied to the median strip on the road as shown in FIG. 8B.

[0004] Therefore, in order to avoid the danger caused by the deterioration of the functioning of the functional structure as described above, it is usually necessary to periodically cut the vegetation in the area near the functional structure, and temporarily remove the plant. Due to the necessity of complicated traffic regulations, time-consuming pruning work and cleaning work after cutting, the labor and cost of management and the cost of disposing of the cut grass and weeds have become enormous. Such a problem has also occurred in places such as parks and idle land such as planned construction sites, which have a large area, and where weeds and the like are not preferable.

[0005]

The present invention has been made in view of such a background, while reducing the time and effort of the above-mentioned maintenance and management while maintaining the scenic effect of the construction base made of vegetation. Another object of the present invention was to develop a new method of forming a scenic surface without causing the functional structure to deteriorate.

[0006]

According to a first aspect of the present invention, there is provided a method of forming a scenic surface, wherein the scenic surface is exposed to a rock, a mortar construction surface, or the like. The vegetation-eliminating landscape is characterized by forming a plant-prevention layer with a composite material of plant powder and a binder. ADVANTAGE OF THE INVENTION According to this invention, in order to prevent the vegetation from fixing and growing on the anti-fixation layer, the labor and cost for maintenance can be significantly reduced.

According to a second aspect of the present invention, there is provided a method for forming a scenic surface.
In addition to the above requirements, the scenic landscape is a combination of a scavenging scrub landscape and a scrub landscape. According to the present invention, the construction base that has undergone vegetation landscape maintenance maintains a greening-like landscape effect such as adaptation to the surrounding landscape by the hue presented by the vegetation, while the construction base that has undergone vegetation elimination landscape has a vegetation removal landscape In order to prevent establishment and growth, labor and cost for maintenance can be significantly reduced.

According to a third aspect of the present invention, there is provided a method for forming a scenic surface.
In addition to the above requirements, the construction surface is a slope, and a plant exclusion landscape is applied near a boundary with a functional structure below the slope. ADVANTAGE OF THE INVENTION According to this invention, especially the slope which causes the remarkable deterioration of the function structure of the lower part by the growing plant can be made into the state which does not cause such a deterioration.

The method for forming a scenic surface according to claim 4 is characterized in that
In addition to the above requirements, the plant powders are characterized by exhibiting a hue suitable for the surrounding scenery. According to the present invention, the fixing prevention layer can be formed so that the surrounding landscape does not have a sense of incongruity, and a natural landscape effect can be maintained.

According to a fifth aspect of the present invention, in addition to the requirements of the third or fourth aspect, the slope includes a retaining stopper having a stopper plate and an anchor pin. It is characterized in that it is provided at intervals to support the seedlings, the whole slope is covered with a wire mesh, and the soil is sprayed.
According to the present invention, it is possible to prevent the soil blown onto the slope by the soil retaining stopper from falling down, and to fix the seedling to the slope.

According to a sixth aspect of the present invention, in addition to the requirements of the third, fourth or fifth aspect, the functional structure is a road or a gutter. . ADVANTAGE OF THE INVENTION According to this invention, since a plant does not cover a road, it can avoid the situation which threatens traffic safety, and can secure traffic safety. Also, since pruning work is not required near the boundary with the functional structure below the slope, traffic regulation and cleaning work associated with maintenance can be significantly reduced. The problem is solved by using the configuration of the invention described in each of the claims.
