Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a greening vegetation for preventing the erosion of a portion of a portion where soil stabilization is desired, such as a slope of a road or a revetment, while vegetating the portion with a plant. Regarding

[0002]

2. Description of the Related Art Planting vegetation for greening is placed in the hollow portion of a legal frame block, and by cultivating plants that have sprouted from the vegetation for greening, while preventing erosion of soil such as road slopes and revetments, A method of greening the part with a plant has been conventionally performed.

As a conventional method, culture soil is first spread on the upper surface of the ground to be laid, a law frame block is laid on it, and then each space portion of the law frame block is laid. There is a plant that directly lays vegetation for greening.

[0004]

However, the above-mentioned conventional method has the following problems. That is, first, the culture soil is spread on the slope or the surface of the ground to be protected, and the culture soil is leveled with a scoop or the like. However, it is inevitable that the culture soil has some irregularities on its surface.
When the greening vegetation is installed on the surface of the ground having such irregularities, the lower surface of the greening vegetation does not adhere to the culture soil, and a gap is created.

As a result, the water absorbed by the culture soil from the ground cannot be supplied to the greening vegetation, and the seeds contained in the greening vegetation cannot germinate or even germinate. There is a problem that it will die soon.
In many cases, the culture soil that spreads is washed out by rain and the effect is halved.

[0006]

[Means for Solving the Problems] The present invention has been made in order to solve the above-mentioned conventional problems, and the vegetation vegetation laid is continuous with the ground and The purpose of the present invention is to provide water supply and effective use of culture soil, and the gist of the invention is to provide a bag made of a water-soluble material in the space of the legal frame block installed on the slope, etc. A greening plant characterized by placing a culture sandbag containing culture soil therein, and installing a greening vegetation in which the voids of a porous concrete hardened body are filled with seeds, fertilizers, medium materials, etc. on the culture sandbag It is in the method of laying vegetation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the embodiments shown in the drawings. In FIG. 1, reference numeral 1 is a greening vegetation, and this greening vegetation 1 is a hardened porous concrete as shown in FIG. 2 and a vegetation base 4 for greening comprising a medium material 3 filled in a lower space 2A of the hardened porous concrete 2
And a mixed layer 7 composed of the seed 5, the fertilizer 6 and the medium material 3 filled in the upper void 2B of the vegetation base 4 for greening.

The porous concrete hardened body 2 has a relatively coarse aggregate 8, 8 as shown in FIG.
Is obtained by adhering and fixing the same with an adhesive material 9 and curing it. 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 diameter 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.

The examples of the composition of the hardened porous concrete 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⁾

A method for producing the greening vegetation 1, that is, a method for filling the lower space 2A of the hardened porous concrete 2 with a medium material 3 to form a greening vegetation base 4, and an upper space. The method of forming the mixed layer 7 by filling the mixture of the medium material 3, the seed 5 and the fertilizer 6 into 2B is not particularly limited, but an example thereof is shown in FIG. Vibration is applied to the hardened porous concrete 2 shown in (a), and the medium material 3 made of soil and pearlite is first charged from the upper surface of the hardened porous concrete 2, and the voids 2A and 2B in the upper and lower parts thereof are introduced.
The medium material 3 is uniformly filled in each.

Next, the filled medium material 3 having a depth of about 8 mm is removed by suction from the upper surface of the porous concrete hardened body 2, and as shown in FIG. 3B, the lower portion of the porous concrete hardened body 2 is removed. 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.

Reference numeral 10 denotes a water-soluble bag made of a water-soluble material such as polyvinyl alcohol, vegetable fiber and starch, or carboxymethyl cellulose.
As shown in FIG.
Are packed and constitute a culture sandbag 12. In the figure, 13 is a rectangular normal frame block, and 14 is a space portion of the normal frame block 13.

Thus, in the construction method of the present invention, as shown in FIG. 5, the method frame block 13 is installed on the surface 15 of the ground G according to a conventional method. Next, in the space portion 14 of the laid method frame block 13, a culture sandbag 12 composed of a water-soluble bag 10 filled with culture soil 11 is put and laid on the surface 15 of the ground G, and the culture sandbag 12 The greening vegetation 1 is put on the top. In this case, since the culture sandbag 12 is deformable, the lower surface 12 of the culture sandbag 12 as shown in FIG.
A is freely deformed into a shape corresponding to the surface 15 of the ground G and comes into close contact with the surface 15 of the ground G.

Therefore, if the greening vegetation 1 is to be continuous with the ground G through the culture sandbag 12,
In the case where a certain amount of rain is taken up from the ground G at a later date, the water-soluble bag 10 of the culture sandbag 12 is melted, and the lower part 11A of the culture soil 11 inside the surface 15 of the ground G and the culture soil 11
The upper part 11B of the above is laid in close contact with the lower surface 1A of the greening vegetation 1 at the time of installation as shown in FIG.

Thus, the greening vegetation 1 is excellent in water permeability, and when rain or the like rains, water immediately permeates into the soil immediately below the greening vegetation 1 and passes through the sandbags 12. Rainwater can be stored in the soil. In addition, when the weather and the like continue to dry, it is possible to absorb water from the soil immediately below the greening vegetation 1 due to the water absorption performance of the sandbag 12, and even without supplying rainwater, the greening vegetation 1 Water can be supplied inside.

[0017]

As described above, the method for laying a greening vegetation according to the present invention is such that the culture soil is placed in the bag formed of the water-soluble material in the space of the legal frame block installed on the slope or the like as described above. Since the culture sandbags that have been placed are placed and the greening vegetation in which the voids of the porous concrete hardened body are filled with seeds, fertilizers, medium materials, etc. is placed on the culture sandbags, the greening vegetation is composed of sandbags. Securely adheres to the surface of the ground through. Therefore, the construction is easy and the work efficiency is improved, and when the weather is dry and the weather continues, the greening vegetation absorbs water from the soil immediately below the greening vegetation due to the water absorption performance of the culture sandbags. Water can be supplied to the greening vegetation even if rainwater is not supplied, and the germination rate will be dramatically improved. There are various effects such that the bag melts out when it is exposed, and the culture soil is kept in close contact between the greening vegetation and the ground at all times even if time elapses.
