Abstract

PURPOSE:To raise constructive efficiency and fixability of vegetating work by a method in which soil is packed into a basket whose bottom has many spaces and planted with turf grass, and the baskets are set and fixed to the sloped ground. CONSTITUTION:In any form of a basket made of plastics or other materials, having many spaces 2 in its bottom, news paper or the like is placed and soil is placed on it for planting turf grass or flowers. The baskets 1 are set on the sloped ground by a valey or staggered stacking way and fixed by anchors. The vegetating work on site can thus be simplified at low cost, and turf grass can be grown stably to prevent the erosion and run-off of the surface soil by flowing water.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope greening method capable of preventing the weathering, erosion and collapse of a slope by vegetation.

[0002]

2. Description of the Related Art The term "slope" generally refers to an artificial slope formed by cutting or embankment, but it may also refer to a natural slope. The slope of the cut soil cuts out the natural ground that was originally stable and destroys the stability, and the slope of the embankment is not yet stable enough in the shallow days after the embankment is constructed. Changes in conditions such as heavy rain can often cause collapse.

There are various causes of slope failure, including erosion due to infiltration of rainwater and groundwater, weathering due to wind and temperature, vibration due to an earthquake, and seismic force.
In order to prevent natural disasters due to such collapse, conventionally, protection by structures such as spraying concrete mortar on the surface has been mainly performed in the past, but the maintenance and greening of the natural environment has become popular. Construction methods using vegetation such as grass have become widely used. When this vegetation method is used, slope protection by vegetation is more permanent than that by structures, construction costs are low, future expansion is not hindered, and the landscape is also excellent. Therefore, in recent years, this method has been widely adopted.

By the way, as a construction method for protecting the slope by vegetation, first, there is a glue frame construction method. Since the cut slope has no water retention property, a secondary product or in-situ casting is used to form a glue frame, and the soil is vegetated by burying the soil in it. It is hard to get used to the soil, and a sloving phenomenon occurs and often slips down. Therefore, the glue frame method is mainly applied to the slope of the embankment. Also, when the slope surface is covered with vegetation by this method, after the seeds are sprayed or artificial turf is spread, erosion partially occurs due to runoff before the roots settle after the construction and the topsoil is removed. It may flow out, and it may be difficult to obtain a good lawn because the germination and growth of the lawn grass may be disturbed. In addition, the use of bamboo skewers is indispensable when arranging turfgrass, and a large number of special workers are required for that purpose, resulting in high labor costs.

Next, there is a construction method in which lath nets are laid and vegetation is made by spraying the soil with the soil. In this case, not only a large spraying machine for spraying is required, but also several After a period of six months, the vegetation slope is exposed and the vegetation base often peels off.

[Problems to be Solved by the Invention]

Therefore, the inventor has completed the present invention by carrying out research in order to eliminate the above-mentioned drawbacks of the conventional construction method. The vegetation work can be carried out at a low cost by a relatively simple work. We have completed the invention of the slope construction method of this case that can be carried out and does not cause erosion or peeling after construction.

[0007]

In the present invention, a basket having an arbitrary shape and material is used, and a large number of vegetation-fixed turfgrass, flowers and the like are produced as one unit, and this is used as a method. A large number of them are placed and fixed on the surface, which makes it possible to eliminate the drawbacks of the conventional construction method.

EXAMPLES The construction method according to the present invention will be described below with reference to examples. FIG. 1 is a perspective view of a rectangular basket 1 used in the present invention, which is made by plastic molding and has an open top and a large number of voids 2 on the bottom and side surfaces. The height of the side wall 3 is around 8 cm. The material of the basket may be plastic, non-ferrous metal, or any other material. Further, the shape may be any shape such as square or hexagon other than the above-mentioned rectangle. The side surface and the bottom surface, especially the bottom surface, having a higher porosity are more preferable, and those having holes such as circular and rectangular shapes, or those having a net shape as a whole may be used. Further, the height of the side wall of the basket is appropriately selected depending on the construction site within the range of 5 to 10 cm.

In the basket 1, first, a paper such as newspaper, which is easily melted in water, is laid, and soil such as improved soil, mixed soil, and culture soil is put on the paper, and turfgrass and flowers are fixed there. It is desirable that the weight of the unit basket be such that the worker can carry it by himself in the completed state.

The mounting on the slope is performed as follows. That is, first, a basket in which the above-mentioned turfgrass is vegetated is placed on the slope, and as shown in FIG. 2, the basket is piled up (falling) so that the corners of the four corners of the basket are located at the sides of the other basket. .. In addition to this, they may be arranged in a staggered arrangement. After the arrangement, the corner portion of the basket is fixed by using the anchor 5 having the pin 4 inserted in the center of the fixing claw as shown in FIG. However, the fixing method is not limited to this, and any method may be used.

[0011]

As described above, according to the present invention, turfgrass and the like are vegetated in a unit basket of any material and shape, and the vegetation is greened by carrying it and fixing it. Therefore, all of the defects that the conventional method has are removed. That is, since the unit basket carries and fixes the vegetation fixed in the factory to the site, the work at the site is completed in one process, the construction process at the work site is simplified, and the labor is reduced.
As for the vegetation after construction, the topsoil is overgrown by the spread of roots of the grass and the creeping above ground, so there is no risk of erosion of the topsoil due to runoff, and the grass grows stably and is excellent in terms of maintenance. ing. Also, since the basket structurally doubles as a glue frame, it does not require a glue frame,
Of course, since the large spraying machine is not required, the construction cost can be greatly reduced.
