Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a greening vegetation for greening a portion of a road, a revetment, etc., where soil stabilization is desired while preventing soil erosion. Regarding legal block.

[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 concrete method of conventional greening, when roughly classified, a legal frame block is installed on the ground, and a greening vegetation is placed in each space of the legal frame block. There is a first method and a second method in which the greening vegetation is integrally formed with the legal frame block at the manufacturing stage, and the legal frame block is installed on the ground.

[0004]

However, the first method is the work of laying the legal frame block and the work of transporting the greening vegetation separate from this to the laid legal frame block. , And the two work of inserting and installing in the space portion of the legal frame block is required, and there is a problem that the construction efficiency is poor. On the other hand, the second method is effective in improving the construction efficiency because it requires only one transfer work and one laying work, but has the following problems.

That is, when laying a legal block,
The slope or the surface of the ground to be protected is leveled with a scoop, and then the level frame block is installed on this leveled surface, but some unevenness is unavoidable. When a law frame block is laid on such an uneven surface, the lower surface of the greening vegetation integrally formed on a part of the law frame block does not adhere to the surface of the ground and a gap is formed. I will end up. This becomes more noticeable when the legal block is large. As a result, the vegetation for greening cannot absorb water from the ground and cannot germinate, or there is a problem that it dies immediately after germinating.

[0006]

[Means for Solving the Problems] The present invention has been made in order to solve the above-mentioned problems of the prior art, and improves the construction efficiency and the bottom surface of the planting for greening after construction is the ground. The purpose of the present invention is to provide a plant that adheres to the surface of the plant and has an improved germination rate. Is fixed to the space portion of the legal frame block via a water wicking sheet that wraps the lower surface and at least both side surfaces of the legal frame block.

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 a mixture of the seed 5, the fertilizer 6 and the medium material 3 filled in the upper void 2B of the greening vegetation base 4.

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 is a square-shaped legal frame block. In the space portion 11 of the legal frame block 10, the planting organism 1 for greening is fitted and fixed via a moisture wicking sheet 12 such as a sponge. There is. That is, in the greening vegetation 1, its lower surface 1A and both side surfaces 1B, 1B have a moisture wicking sheet 1
It is wrapped with 2 and is fitted in the space portion 11 of the legal frame block 10 in this state. Therefore, the greening vegetation 1
Is fixed in the space portion 11 of the legal frame block 10 via the upright portion 12A of the suction sheet 12 that wraps both side surfaces 1B, 1B thereof.

Therefore, as described above, the greening vegetation 1
Of the legal frame block 10 fixed in the space 11 as shown in FIG.
As shown in FIG. 4, when the green sheet is placed on the surface 13 having a level G such as a slope, the lower surface 1A of the greening vegetation 1 has a moisture wicking sheet 1
It is in close contact with the surface 13 of G such as the slope via 2. In addition, in the embodiment shown in the drawings, the description was made with the relatively small legal frame block 10 having one space portion 11, but there is also a large legal frame block in which a plurality of space portions 11 are formed. The method is the same as above.

As described above, the vegetation 1 for greening is laid on the sloped frame frame 10 in which the space 10 is fixed on the leveled surface 13 such as a slope G. Irregularities 13 on the surface 13 of the portion where the living organism 1 is installed
Even if there is A, as shown in FIG. 5, the moisture wicking sheet 12 elastically deforms into the same shape as the unevenness 13A on the surface, and adheres to the surface 13 such as the slope G.

Thus, the greening vegetation 1 is excellent in water permeability, and when rain or the like rains, the green vegetation 1 immediately penetrates into the soil immediately below the greening vegetation 1 through the moisture wicking sheet 12. , It is possible to store rainwater in the soil. In addition, when the weather and the like continue to dry, the moisture wicking performance of the moisture wicking sheet 12 allows moisture to be wicked from the soil immediately below the vegetation 1 for greening, and vegetation for greening can be provided even if rainwater is not supplied. Water can be supplied into the body 1.

[0017]

As described above, the method frame block with greening vegetation according to the present invention has the lower surface of the greening vegetation in which the voids of the porous concrete hardened body are filled with seeds, fertilizers, medium materials and the like. Since it is fixed to the space of the legal block through the water wicking sheet that wraps at least both sides, it only needs to be transported and laid once when constructing,
As the work efficiency improves, the lower surface of the greening vegetation surely adheres to the surface of the ground via the water absorption sheet, so that it is possible to absorb the moisture from the ground and the germination rate is significantly improved. effective.
