Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a greening protection device for a concrete surface, which is made for disaster prevention in parks on steep slopes, mountains and hills. By installing it on a retaining wall, a wall of concrete block piles, or a surface such as a slope made of concrete or mortar spraying, the tasteless dry slope created by artificial construction will be changed by natural greening and reconstructed, and in the urban area Aims to harmonize with buildings and to improve the scenery in tourist areas without damaging the surrounding scenery.

[Conventional technology]

Slope protection work is widely known to protect fragile rocks and slopes, either artificially or by planting or sowing.

Among them, the concrete retaining wall, the wall of concrete block piles, and the artificial slope created by concrete or mortar spraying work can stabilize the slope ground over a wide range by a spraying machine in a short period of time, and it is even and strong. It is popular as a work that can be maintained.

[Problems to be solved by the device]

However, the surface of the concrete retaining wall is smooth, and the wall surface of the concrete block stack has a so-called mesh screen or grid pattern, and the artificial slope by concrete or mortar spraying is finished. The surface is formed up and down along the ground, and although there are geometric forms and a kind of structural appearance, the retaining wall of the concrete, the block wall surface or the concrete mortar spray slope is exposed as it is. Because it does not provide a natural aesthetic landscape, and there is no natural greening at all, it does not serve as an eye candy, and the urban area has a theory that it lacks harmony with the buildings and surrounding scenery in tourist areas. The landscape is extremely poor.

[Means for Solving the Problems]

Therefore, the present invention solves the drawbacks in the existing concrete retaining wall, the concrete block wall surface, or the artificial slope by concrete or mortar spraying,
And it is provided to achieve the purpose of the invention.

The present invention relates to a concrete surface greening protection device, in which at least a lower part forms a curved surface, and the curved concave arc surface faces inward, and a reinforcing bar is attached along the upper end side and the lower end side of the elongated net body, and A frame in which curved portions that match the curved surface of the net body are formed at both ends of the net body,
A basket is formed by mounting a side panel with a net stretched inside the frame, and an anchor hole is made in the rear surface of the frame on the side panel, and an anchor bolt is passed through this to form a concrete retaining wall, wall surface or slope side. Fixed to the surface of the basket, the coarse fiber mat is attached along the upper edge of the basket, and the mat is spread from the inner surface of the net to the surface. Is planted with greenery plants such as vines or low soil.

[Action]

The operation of the present invention based on the above means will be described. First, mark the planting position of the anchor bolt on the surface of the existing concrete retaining wall surface, concrete block wall surface or concrete / mortar spray slope, then make a hole and insert the base side of the anchor bolt into the hole. Then, mortar or cement milk is filled in the drilled hole and fixed.

Next, insert anchor bolts through the holes of the frame arranged on the left and right corresponding to the horizontally long position of the net body and temporarily fix it with nuts, attach the horizontally long net body to the side panel and fix it with screws, then temporarily fix The work of fixing the basket to the above-mentioned surface side by further tightening the nut on the placed anchor bolt is completed.

Next, the coarse fiber mat is attached along the upper end side of the horizontally long net body, and is laid along the inner surface of the net body so as to extend to the opposite surface side. Then, the customer bag is stored in the coarse fiber mat so as to be dropped from the opening of the basket. Then, the top surface of the housed bag is cut open to plant green plants. If necessary, pebbles and mat-shaped mulch materials are spread over the roots of the planted green plants.

The above-mentioned coarse fiber mat has a function of insulating heat from the outside, and the mulch material has a function of preventing weed seeds from adhering to the soil and preventing drying.

The reinforcing bars 2 and 3 are fixed by welding along the side and the lower end side. The size of the net body is arbitrary according to the construction site, but in the illustrated example, the length is set to about 1,800 mm and the height is set to about 450 mm.

Reference numeral 4 designates a frame 5 formed of metal strip steel having curved portions r'formed on the left and right ends of the net body 1 to match the curved surface of the net body, and the same material as the net body or punching metal in the frame 5. It is a side panel having a net 6 stretched over it. The frame 5 may be D-shaped or half-moon shaped, with its convex arcuate portion serving as the front surface and the opposing side portion serving as the rear surface that contacts the surface a.

Reference numeral 7 is an anchor hole formed on the rear surface side of the frame 5, 8 is an anchor bolt, and is an anchor for a hole 7 previously made on a surface a such as a concrete retaining wall or a concrete block wall surface or a concrete / mortar spray slope. After the base of the bolt 8 is planted, mortar or cement milk is filled and fixed.

Spread it. Subsequently, the customer bag 10 is stored in the coarse fiber mat so as to be dropped from the opening of the basket b.

Then, the upper surface of the soil bag 10 housed in the basket b is cut open to plant a greening plant w such as vines or shrubs, and pebbles or mat-shaped mulch material 12 is spread at the root thereof.

[Effect of device]

Since the present invention has the above configuration, it has the following effects. That is, by applying the greening protection device according to the present invention to an existing concrete retaining wall, a wall surface of concrete block piles, or a surface such as concrete or mortar spray slope, plants can be planted on artificially created tasteless concrete surface. Prosperous natural greening can be realized.

Further, the basket is not bulky due to the disassembled assembly structure of the horizontally long net body and the side panel, which is convenient for production or storage, and at the time of construction at the site,
It can be easily and surely attached and fixed with anchor bolts.

Furthermore, since the basket uses a wire net, it is relatively light and easy to handle, even though it is made of metal compared to a metal iron plate, and the greening protection work on a steep slope can be efficiently performed.
