[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening vegetation for greening a portion of a riverbed, a slope or the like where soil stabilization is desired with a plant.

[0002]

2. Description of the Related Art Conventionally, as this kind of vegetation for greening, hardened porous concrete is mixed with seeds, fertilizers, water-retaining materials, moisture wicking materials, etc. (JP-A-3-36).
324, JP-A-5-272142, JP-A-6-113866) and a seeded concrete block (cement-bonded coarse aggregate having air permeability and water permeability) with plant seeds. Many have been developed, including mixed ones (Japanese Patent Publication No. 6-56020).

[0003]

[Problems to be Solved by the Invention] Then, on the slope, the greening vegetation is placed in the hollow portion of the existing or new slope frame block, or on flat ground, one by one is installed on the ground. However, in the former, there is a problem that the aesthetic appearance is impaired and the workability is poor because the legal block is exposed. In addition, there is also a method to install the greening vegetation directly on the slope, but when it slides down along the slope or during heavy rain, it is washed away not only on the slope but also on the flat ground,
There is a problem that a predetermined position cannot be greened.

Further, the seeds of plants are germinated from the surface of the greening vegetation, but in places where the installation conditions are severe, the seeds cannot be sucked up from the ground and the seeds do not germinate, or direct sunlight is emitted before germinating. In the summer, especially when the greening vegetation itself becomes extremely hot, the surface layer of the greening vegetation does not dry and does not germinate, or even if it germinates it is exposed to strong direct sunlight. There is a problem that it will die soon.

Further, immediately after the construction, the seeds filled in the surface layer of the greening vegetation may flow out due to wind and rain. On the other hand, in the invention of Japanese Patent Publication No. 6-56020, such a problem is thought to be solved,
There is a problem in terms of germination rate because the seeds are completely covered with cement. Since the greening vegetation has a configuration in which seeds, fertilizers, water retention materials, moisture wicking materials, etc. are mixed in the hardened porous concrete, the structural strength is weak, and the vegetation for crushing is crushed during transportation or construction, or There is also a handling problem that there is a risk of damage and that careful handling is required.

[0006]

[Means for Solving the Problems] The present invention has been made in order to solve the above-mentioned conventional problems, and improves the construction efficiency and germination rate, and the seeds runoff due to wind and rain after the construction. The purpose is to provide a vegetation base for revegetation whose upper surface is covered with seeded sardines when the medium and fertilizer are filled in the voids of the hardened porous concrete. In the greening vegetation, a large number of vegetation are mounted on the water-permeable sheet at intervals on the lower surface thereof.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in FIGS. 1 and 2. In FIG. 1, 1 is a greening vegetation according to the present invention, and this greening vegetation 1 is a hardened porous concrete. 2 and the void 2A of the hardened porous concrete 2
A vegetation base 5 for greening in which the medium material 3 and the fertilizer 4 are filled,
Cold gauze 7 with seeds 6 covering the upper surface of the vegetation base 5 for greening
And a water-permeable sheet 8 in which a large number of vegetation bases 5 for greening, which are covered with the Chinese sardine cloth with seeds 6, are mounted at intervals. The fertilizer 4 may be filled only in the surface layer of the vegetation base 5 for greening.

The green vegetation base 5, that is, the hardened porous concrete 2 which constitutes the green vegetation base 5, is 30 cm × 30 cm × 10 cm in length, width, and height in the illustrated example. As shown in FIG. 2, it has a cubic shape and is obtained by bonding and fixing relatively coarse aggregates 9 and 9 with an adhesive material 10 and curing the same. Therefore, although the aggregate 9 has almost no air permeability or water permeability, a void 2A is formed between the aggregates 9 and 9 and this shape is retained by the adhesive fixing by the adhesive material 10. The hardened concrete body 2 as a whole is porous and has air permeability and water permeability.

Here, the aggregate 9 has a particle size of about 2.5.
Crushed stone of about 40 mm is used, and various cements such as Portland cement and blast furnace cement are used as the adhesive 10. Further, as the medium material 3, a mixture of soil with 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.

Desired performance can be imparted by adjusting the type and particle size of the aggregate 9. Moreover, you may use an admixture as needed. Further, the shape of the hardened porous concrete 2 is a rectangular parallelepiped cube, a panel shape,
Any shape such as a rhombus may be used, and the shape can be changed according to the application. Further, the type of seed 6 is not particularly limited and may be appropriately selected according to the purpose.

Further, the hardened porous concrete 2
Examples of the composition of are listed in Table 1 below.

[Table 1] Water 48.90 (kg / m ³ ) Ordinary Portland cement 259.00 (kg / m ³ ) Silica fume 0 (kg / m ³ ) Aggregate (crushed stone, particle size 10 to 20 mm) 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⁾

The method for manufacturing the vegetation base 5 for greening, that is, the method for filling the voids 2A of the hardened porous concrete 2 with the medium material 3 and the fertilizer 4 is not particularly limited. Vibration is applied to the porous concrete hardened body 2 fixed on the table, and a mixture of the medium material 3 made of soil and pearlite and the fertilizer 4 is introduced from the upper surface of the porous concrete hardened body 2,
The simplest method is to uniformly fill the voids 2A with the medium material 3 and the fertilizer 4.

[0013] In addition, the cheesecloth 7 with seeds 6 covering the upper surface of the vegetation base 5 for greening is a sheet coarsely knitted with synthetic fibers twisted with the seeds 6 of the plant sandwiched between them, or coarse with synthetic fibers. The seeds 6 are fixed to a knitted sheet by an adhesive so that the coarse meshes of the seeds can sprout the plants, and the chilled gauze 7 with the seeds 6 is integrated when the porous concrete hardened body 2 is molded. Or to the surface of the vegetation base 5 for greening with an adhesive such as cement paste.

Therefore, in the case where the above-mentioned cheesecloth 7 with seeds 6 is integrally attached at the time of forming the hardened porous concrete 2, a mixture of the medium material 3 consisting of soil and perlite and the fertilizer 4 is placed on the cheesecloth 7 with seeds 6. Then, the medium material 3 and the fertilizer 4 are uniformly filled in the voids 2A of the hardened porous concrete 2 through the coarse mesh of the sardine cloth 7 with seeds 6.

The vegetation base 5 for greening, the upper surface of which thus formed is covered with the cheesecloth 7 with seeds 6, is about 2 m × 5 m.
A large number of water-permeable sheets 8 each having a size of about 8 cm are mounted on the water-permeable sheet 8 at intervals of about 8 cm.
Therefore, the medium material 3 and the fertilizer 4 in the vegetation base 5 for greening do not spill. Further, since the water in the soil is diffused over the entire bottom surface, the water can be uniformly supplied into the vegetation base 5 for greening, and the effect of preventing the soil from being sucked out from the construction ground can be added. Such a water permeable sheet 8
Examples of the non-woven fabric include a non-woven fabric, and specifically, non-woven fabric “HP-21” manufactured by Nippon Vilene Co., Ltd.

The method of mounting the greening vegetation base 5 on the water permeable sheet 8 is as follows.
Laying on it, an inner frame in the shape of a Horai girder, in which a large number of box frames of the above-mentioned size of the porous concrete hardened body 2 are formed at intervals, is placed, and in each box, concrete composed of the composition shown in Table 1 is placed. If the cast concrete is cast and then demolded after curing, the porous concrete cured body 2 integrated on the water permeable sheet 8 becomes
A large number will be mounted at desired intervals. And
The method for filling the voids 2A of the porous concrete cured body 2 with the medium material 3 and the fertilizer 4 to form the vegetation base 5 for greening is as described above.

Thus, in the method of constructing a greening vegetation according to the present invention, the greening vegetation 1 is laid on the ground of a portion to be greened such as a slope or a flat land with the water permeable sheet 8 facing down. However, if the slope of the slope is large, metal fittings or the like may be driven into the water permeable sheet 8 from above between the greening vegetation bases 5 to fix it to the ground. In addition, culture soil may be placed in the spaces between the vegetation bases 5 and 5 for greening. In this way, since each greening vegetation base 5 of the greening vegetation 1 is continuous with the water permeable sheet 8, it does not slip down or be washed away by rainfall even if it is not put in the hollow portion of the legal frame. .

The vegetation 1 for greening is excellent in water permeability, and when rain or the like falls, the vegetation 1 for greening immediately penetrates into the ground immediately below the vegetation 1 for greening, and rainwater can be stored in the ground. it can. Also, when the weather is dry and continues,
Water can be absorbed from the soil directly below the greening vegetation 1 by the medium material 3, and water can be supplied into the greening vegetation without the supply of rainwater.

Further, since the greening vegetation 1 is provided with a cheesecloth 7 with seeds 6 on the surface thereof, the plant seeds 6 after the construction.
Before the seeds germinate, the temperature of the vegetation base 5 for revegetation and the surface of the vegetation base 5 for sunlight are moderated to create an environment suitable for sprouting, and at the same time prevent the seeds 6 from scattering and flowing out due to wind and rain. be able to. In addition, during the period just before germination, strong direct sunlight in summer can be shielded to some extent to protect buds and prevent mortality, and the seedling 6 kanshisa 7 is used as a reinforcing material for the vegetation base 5 for greening. The above function is also fulfilled, and damage to the greening vegetation 1 during transportation or construction can be prevented as much as possible.

EFFECTS OF THE INVENTION The greening vegetation according to the present invention, as described above, is filled with a medium material and fertilizer in the voids of a hardened porous concrete to form a greening vegetation base whose upper surface is coated with seed-bearing ginseng. Since the lower surface thereof is mounted on the water-permeable sheet in large numbers at intervals, the construction is easy and the construction period can be shortened. And since each vegetation base for greening is continuous with a water permeable sheet, it does not slip off even if it is not put in the hollow part of the legal frame block, it is not washed away by rainfall, and the medium material etc. does not spill Because it is not damaged, it is easy to handle, and the germination rate is improved, and the moisture in the soil is diffused over the entire bottom surface,
Since the water can be supplied uniformly, it is possible to germinate evenly, and since the earth and sand are prevented from being sucked out from the construction ground, the slope can be protected. In addition, since the upper surface of each vegetation base for greening is covered with seed-cold gauze, seeds will not flow out even if exposed to wind and rain immediately after construction, and direct sunlight will be shielded to raise the vegetation base for greening. Prevents temperature and dryness, creates a favorable environment for germination, and improves the germination rate. In addition, since there is only a planting plant for greening, it can be manufactured at a low price, but there are various effects that it does not spoil the aesthetics.
