BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation base used for constructing a greening foundation board made of concrete or the like.

[0002]

2. Description of the Related Art Conventionally, when a vegetation base material is used to build a greening base on a slope using concrete or the like, a permeable material is used to spray the concrete directly onto the vegetation base material or to give the concrete the property of allowing water to permeate. The method of mixing in was commonly used.

[0003]

However, the conventional construction method as described above has the following problems.
That is, in the conventional method of spraying concrete directly on the vegetation base material, because the water is drained only by the water permeation performance of the vegetation base material, the water permeation performance decreases with the passage of time, and water accumulates in the vegetation base material. The water content was excessive, the ventilation was poor, and the roots of the plants were rotted. Since the surrounding area was covered with concrete, heat was accumulated and pathogenic bacteria were generated. In addition, with the method of giving concrete the property of permeable water, drainage is improved and there is no concern about root rot, etc.
Since a water-permeable material is compounded, it becomes expensive, and a concrete is made porous by mixing a water-permeable material, so a decrease in strength cannot be avoided. In addition, when the vegetation base material is covered with a braided vegetation base material and the drainage material and the heat insulating material are installed on the outside, the performance of the heat insulating material is deteriorated or damaged when concrete is sprayed on the heat insulating material. There was something that happened.

[0004]

In view of the above-mentioned drawbacks of the conventional method for constructing a greening foundation board, the present invention encloses the right and left sides of the vegetation base material with protective sheets, and removes the outer periphery except the upper surface. Since the vegetation base material is covered with drainage material and the outer periphery is covered with a heat insulating material, and the vegetation base material with a rough top surface and a basket with finely meshed side surfaces is used, drainage and heat retention are appropriate. Therefore, plant growth is good, and there is no risk of deterioration in strength.

[0005]

In order to achieve the above-mentioned object, the vegetation base material of the present invention has a drainage material attached around the vegetation base material so that excess water in the vegetation base material can be passed through the drainage material. In addition, since a heat insulating material is installed around the drainage material of the vegetation base material in order to prevent the generation of pathogenic bacteria due to the temperature rise of the vegetation base material, the temperature rise and temperature decrease of the vegetation base material can be prevented and the drainage can be prevented. It is possible to provide a growth environment suitable for plants by adjusting the temperature by the air permeability of the material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described below with reference to FIG.

A vegetation base material 2 in which a sandbag 1 is mixed with a greening base material such as bark or peat moss, a fertilizer and seeds and packed.
A drainage material 4 such as rock wool having a continuous void is attached to the outer circumference of the pyramid of, and further covered with a heat insulating material 5 such as styrofoam, and the outer circumference is further covered with a basket 3 having a rough upper surface and finely meshed side surfaces. It is a thing. When the drainage area of the left and right ends is smaller than the drainage area of the front, the left and right ends are covered with the protective sheet 6 without using drainage or heat insulating material, and the drainage of the vegetation base is It does not hinder the function.

[0008]

[Effects of the Invention] According to the vegetation base material of the present invention, the following effects can be obtained.

Since the drainage material is arranged on the outer periphery of the vegetation base material, the ventilation is good, and excess water can be drained quickly, so that root rot of the plant does not occur. Moreover, since the heat insulating material is installed on the outer periphery of the drainage material, the temperature can be controlled and the growth of the plant becomes good.

Since the outer circumference of the vegetation base material is covered with a heat insulating material, the vegetation base material is not affected by spraying a hardened material such as concrete, and the growth of the plant is not hindered.
In addition, since the heat insulating material is also covered with a braided basket, it is possible to reinforce the concrete during concrete spraying,
It is possible to prevent the heat insulating material from being damaged by the spraying force of concrete.

Since the drainage material and the heat insulating material may be installed inside the braided basket, the manufacturing process can be simplified and further, the manufacturing process, the transportation process and the construction process will not be damaged. The product can be provided at a reasonable price.

Since conventional mortar or concrete can be used for spraying, the strength of the vegetation base material is not reduced, and the vegetation base material is covered with a heat insulating material or a drainage material, so that freezing, etc. It has various features that can prevent cracking of concrete due to.
