DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings. In FIGS. 1 to 3, reference numeral 1 is a simplified green side groove according to the present invention, which has an L-shaped cross section. There is. As shown in FIG. 2, the simplified green gutter 1 for greening includes a hardened porous concrete 2 and a greening vegetation base 4 made of a medium material 3 filled in a lower void 2A of the hardened porous concrete 2. , Seed 5, fertilizer 6 and medium material 3 filled in the upper void 2B of the vegetation base 4 for greening
And a mixed layer 7 made of a mixture of

The hardened porous concrete 2
As shown in FIG. 3 (a), is obtained by adhering and fixing relatively coarse aggregates 8 and 8 with an adhesive 9 and curing the same. Therefore, the aggregate 8 has almost no air permeability or water permeability, but the voids 2A and 2B are formed between the aggregates 8 and 8 and the shape is maintained by the adhesive fixing with the adhesive 9. As a whole, the porous concrete hardened body 2 is porous and has air permeability and water permeability.

Here, the aggregate 8 has a particle size of 2.5 to
Crushed stone of about 40 mm is used, and as the adhesive 9, mixed cement such as various Portland cement and blast furnace cement is used. As the medium material 3, a mixture of soil and perlite, a pulverized product of hardwood pulp, cellulose powder, crystalline cellulose, or the like is used. The porosity of the porous concrete hardened body 2 is set to 25 to 35% in consideration of the ease with which the roots of plants are stretched and the ability to absorb water due to the capillary phenomenon.

Examples of the composition of the porous concrete hardened body 2 are shown in Table 1 below.

TABLE 1 Water 48.90 (kg / m ³⁾ ordinary portland cement 259.00 (kg / m ³⁾ Aggregate [crushed stone, grain size 10~20mm] 1501.00 (kg / m ³⁾ relieving agent [Kao "mighty 150"] 5.18 (kg / m ³⁾ AE agent [Kao "mighty AE03"] 0.1295 (kg / m ³⁾

Further, a method for producing the simple greening side gutter 1 for greening, that is, a method for filling a lower space 2A of the hardened porous concrete 2 with a medium material 3 to form a greening vegetation base 4, and an upper part. Medium material 3, seeds 5 in the void 2B
The method for forming the mixed layer 7 by filling the mixture including the fertilizer 6 and the fertilizer 6 is not particularly limited, but an example thereof is as follows:
Vibration is applied to the porous concrete hardened body 2 shown in FIG. 3 (a) fixed on the vibration table, and the medium material 3 made of soil and pearlite is first introduced from the upper surface of the porous concrete hardened body 2 and its upper part. And the lower void 2
The medium material 3 is uniformly filled in each of A and 2B.

Next, the filled medium material 3 having a depth of about 8 mm is removed by suction from the upper surface of the hardened porous concrete 2 and, as shown in FIG. The medium material 3 is filled only in the voids 2A to form the vegetation base 4 for greening. Then, the upper portion void 2B of the greening vegetation base 4 from which the medium material 3 has been removed
Then, the mixture consisting of the seed 5, the fertilizer 6 and the medium material 3 is filled by the same method as described above to form a mixed layer 7 on the upper part of the vegetation base 4 for greening as shown in FIG. The simplest method is to do so.

FIG. 4 and FIG. 5 show a simple greening side groove 11 having a spoon-shaped cross section, which is different from the above-mentioned simple greening side groove 1 for greening only in other configurations. It is the same as the mold side groove 1. In the present invention, desired performance can be imparted by adjusting the type and particle size of the aggregate 8. Moreover, you may use an admixture as needed. Furthermore, the type of seed 5 is not particularly limited and may be appropriately selected depending on the purpose.

Thus, the simple greening gutter according to the present invention is excellent in water permeability, and quickly penetrates into the ground immediately below the simple greening gutter 1 (11) when it rains. Water does not collect on the upper surface as it goes. Then, when the weather and the like continue to dry, the permeated water and the like can be sucked up from the ground G immediately below the simple type gutter 1 (11) for greening due to the water suction performance of the medium material 3, and the supply of rainwater. Simple type gutter 1 (11) for greening without
Water can be supplied inside.

Therefore, the simplified type side groove 1 (11) for greening
The seeds 5 inside germinate, and plants such as flowers can grow and grow from the upper surface. And, dust collects on the upper surface of the greening type gutter 1 (11), but when the dust is hidden by the growing plants, it does not fly up to the ground due to the wind, and in terms of aesthetics, It is also effective in terms of environmental hygiene.

[0015]

As described above, the simplified green gutter for greening according to the present invention comprises a porous concrete hardened body having the shape of the simplified type gutter, and a medium material filled in the lower voids of the porous concrete hardened body. Since it is composed of a greening vegetation base formed, and a mixed layer consisting of seeds, fertilizer and medium material filled in the upper voids of the greening vegetation base,
It becomes porous, breathable and water permeable, and when it rains, it immediately penetrates into the soil directly under the simple greening gutter for greening, and rainwater can be stored in the soil. When the amount of rainfall is large, it functions as a gutter.
Also, when the weather is dry and continues to dry, it is possible to absorb water from the soil directly below the simple greening gutter due to the water absorption performance of the medium material, and even in the simple greening gutter for greening even if rainwater is not supplied. Water can be supplied to the rice, which has various effects such as an improved germination rate.
