(57) [Abstract] [Purpose] By attaching drainage material around the vegetation base, drainage can be performed both inside and outside the vegetation base, and at the outer periphery of the vegetation base. It is to provide a growth environment suitable for plants by arranging a heat insulating material. [Structure] The present invention comprises a drainage substrate having the following structure. That is, (1) The vegetation base material was packed in the frame body, and at least the upper surface was removed, and the outer periphery was covered with drainage material. (2) Except at least the upper surface of the vegetation base material, the outer periphery is covered with drainage material. (3) Except at least the upper surface of the enclosure of the frame body, it is covered with drainage material, and a vegetation base material is driven in in a later step. (4) A heat insulating material was attached to the outside of the drainage material. (5) Remove the protective sheet at the top opening with a drainage substrate covered with drainage material or heat insulating material in a later step. With the above configuration, a growth environment suitable for plants can be provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage base body that prevents root rot of plants by using drainage material for draining and aeration of the vegetation base when constructing a greening foundation work with concrete using a frame or a vegetation basement.

[0002]

[Prior Art]

 Conventionally, when constructing a legal framework, that is, a greening foundation work with concrete using a vegetation base, concrete is sprayed directly on the vegetation base or a permeable material is mixed in order to give the concrete a water permeable property. The method of doing was common.

[0003]

[Problems to be solved by the device]

 However, such a conventional construction method has the following problems. That is, in the conventional method of directly spraying concrete onto the vegetation base material, the water is drained only by the water permeability of the greening base, so the water permeability deteriorates over time, water accumulates, and water becomes excessive. Due to poor ventilation, the roots of the plants were rotted, and the surrounding area was covered with concrete, resulting in the heat buildup and the generation of pathogenic bacteria. In addition, the method of making concrete permeable has good drainage and there is no concern about root rot, but it is expensive because it mixes a permeable material, and concrete is made porous by mixing a permeable material. Therefore, the decrease in strength was unavoidable.

[0004]

[Means for Solving the Problems]

 In view of the above-mentioned drawbacks of the conventional method of constructing a greenery foundation work, the present invention has drainage material arranged on the outer periphery of the vegetation base body and is further covered with a heat insulating material. It is drained by the drainage material provided on the outer periphery of the building and is also insulated by the surrounding heat insulating material.

[0005]

[Action]

 In order to achieve the above object, the drainage foundation of the present invention has a drainage material attached around the vegetation foundation, so that not only the drainage inside the vegetation foundation but also the drainage can be performed by the drainage material. It is attached around the vegetation base. In addition, since the heat insulating material is placed around the vegetation base to prevent the generation of pathogenic bacteria due to the temperature rise of the vegetation base, the temperature rise and temperature decrease are prevented, and the air permeability of the drainage works to maintain the temperature. To provide a suitable growth environment for plants.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The outer circumference of the vegetation base body 2 in which sandbags 1 are mixed with greening base materials such as bark and peat moss, fertilizers, and seeds and filled with a frame 3 such as a wire netting cage is continuously emptied A drainage material 4 having a gap is attached and further covered with a heat insulating material 5 such as polystyrene foam.

If the drainage material 4 and the heat insulating material 5 are hard and can retain their shapes, the frame 3 such as a wire netting cage may be omitted.

The sandbag 1 may be omitted as long as the vegetation base 2 can be mixed with cement, a polymer adhesive or the like to maintain its shape.

In some cases, at least the upper surface around the frame 3 is covered with the drainage material 4, and the vegetation base material is driven in in a later step.

When using the drainage substrate according to the present invention, for example, the drainage substrate according to the present invention having a wide front-back width as shown in FIG. 4 is attached to the slope 6 stepwise. If necessary, install a drainage pipe (not shown in the drawing) under each drainage base, and spray a hardened material 7 such as concrete on the periphery of each drainage base except the top surface of the drainage base. The plants are planted on the upper surface in advance or planted with plant seedlings for greening. Before spraying the hardened material 7 such as concrete, a protective sheet is placed in advance on the upper surface of each drainage base body, and after spraying the hardened material 7 such as concrete, the protective sheet is removed to ensure the planting surface. Is formed.

[0012]

[Effect of the device]

 As described above, according to 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 excess water is drained quickly, and root rooting does not occur.

Since the drainage material is arranged on the outer periphery of the vegetation base material, spraying a hardened material such as concrete does not affect the vegetation base material and does not hinder the growth.

Since the drainage material is arranged on the outer periphery of the vegetation base material, the ventilation is good, the temperature can be adjusted and oxygen can be supplied, and the growth is good.

Since the heat insulating material is arranged on the outer periphery of the vegetation base material, the temperature can be adjusted.

Since the drainage material and the heat insulating material are attached to the outer circumference, it is possible to respond to a design change.

Since conventional mortar and concrete can be used, the strength does not decrease.

Since the vegetation base material is covered with the heat insulating material and the drainage material, the concrete is not adversely affected by freezing or freezing.
