DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a planting structure of a planting material.

[0002]

2. Description of the Related Art Conventionally, when a mountain surface is exposed due to construction or road maintenance, or in a revetment wall such as an embankment,
Apply soil to the slope to prevent the outflow and collapse of sediment and to prepare the landscape by the following methods, and spray seeds and fertilizer on it, or directly apply the soil to the slope with seeds and fertilizer. Spraying and plant roots are used to suppress the outflow of the soil, reinforce the slope and revegetation.

[0003] However, in this method, since the soil is easily peeled off from the slope by rainwater or the like before the plants take root, it is hardly possible to construct the steep slope. In view of the above, a conventional greening base is proposed in Japanese Patent Application Laid-Open No. Hei 6-228965, in which the gap between the conventional planting base materials is filled with soil containing an acidic water retaining material such as peat moss or fertilizer to enhance water retention. Have been.

[0004] However, even though the greening base has improved water retention, it has a process for forming a planting base material and a process for filling with a water retention material and soil, so that the production workability is poor and the production cost is high. With a tilt angle of at most 65 ° (2 /
It can be constructed only up to the slope of 1). That is, greening cannot be achieved by constructing a vertical surface such as a wall surface of a building.

[0005]

SUMMARY OF THE INVENTION In view of such circumstances, the present invention provides a planting structure of a planting base material capable of greening even a large angled inclined surface or a vertical surface. It is intended to be.

[0006]

The planting structure of the planting substrate according to the present invention includes a montmorillonite-based clay mineral and a plant-based natural organic material in order to achieve such an object.
A mixture in which these are dispersed and mixed, a plurality of plate-shaped planting base materials having a water retention property, which are solidified in a porous state by a synthetic resin binder, are arranged along an inclined planting surface. The edge of the planting base material was supported by the support member and was fixed at a predetermined position on the planting surface.

In the above structure, the montmorillonite-based clay mineral is not particularly limited as long as it has a water-retaining property. Name).

The particle size of the montmorillonite clay mineral is not particularly limited, but is preferably about 150 to 20 mesh. That is, if the particle size is larger than 20 mesh, there is a possibility that sufficient shape retention may not be ensured.
If it is less than 0 mesh, it may be too dense to deteriorate irrigation and workability.

[0009] The vegetable natural organic matter is not particularly limited, and includes, for example, peat moss (grass charcoal), sawdust, thinned wood and crushed waste wood, and peat moss is preferred. The peat moss is an unadjusted product and usually has a pH of 3.
Although the pH is about 5 to 5.5, the pH of the montmorillonite clay mineral is about 7.0 to 8.5, so that the pH is almost naturally set to 6.0 to 7.5 by mixing with the montmorillonite clay mineral. Can be

Synthetic resin binders which have film-forming properties and swelling properties, have shape retention properties even when swollen, hardly elute from cured products into water, and have no effect on plants or the natural environment Preferred are, for example, acrylic resins, vinyl acetate resins, copolymers thereof, and urethane resins having equivalent properties. Further, a biodegradable plastic may be used.

In addition to the above-mentioned montmorillonite-based clay mineral and vegetable natural organic matter, the mixture may optionally contain, for example, porous granules such as perlite, fertilizer components such as vermiculite and oil residue, and pH adjusters such as lime. Etc. can also be added. Also, seeds of a plant to be planted may be mixed.

That is, for example, the addition of vermiculite improves fertilizer retention and the like, and the addition of perlite increases the initial water absorption rate, which is effective when the frequency of irrigation is low and a large amount of irrigation is performed temporarily. By adding lime, desired functions such as neutralization of acidic components such as peat moss can be added.

The mixing ratio of the montmorillonite-based clay mineral to the plant natural organic matter and the mixing ratio of the mixture to the synthetic resin binder are adjusted depending on the place where the plant base material is laid, the type of plant to be planted, the use, and the like. However, by the way, using galeonite HK as a montmorillonite clay mineral,
When peat moss is used as a vegetable natural organic matter, the mixing ratio of galeonite HK and peat moss is preferably 30 to 90% by weight of galeonite HK, when the total amount of galeonite HK and peat moss is 100% by weight.

That is, 30% by weight of galeonite HK is contained.
If it is less than 90%, the self-shape cannot be maintained, and all post-processing may not be possible. If it exceeds 90% by weight, it may be hard like a stone, workability may be deteriorated, and water retention may be lost. . Further, plant seeds may be mixed in advance with plant seeds.

The method for producing the planting base material is not particularly limited, but is a method in which a slurry-like molding material containing a montmorillonite-based clay mineral, a vegetable natural organic substance, and a synthetic resin binder is put into a mold and pressed. Is mentioned.

In the above-mentioned production method, the synthetic resin binder is preferably used in the form of an emulsion mixed with water. Specifically, acrylic copolymer emulsions such as Movinyl 710 (trade name manufactured by Hoechst Gosei), Movinyl 718 (trade name manufactured by Hoechst Gosei), lunasol AH (trade name manufactured by Hoechst Gosei), and polysol (Trade name of Showa Kogaku Co., Ltd.), Lone Fix 2
It is preferable to use an ethylene-vinyl acetate copolymer emulsion such as 00 (trade name of Showa Polymer Co., Ltd.).

[0017] The press-formed product is not particularly limited, but is preferably heated and forcibly dried to obtain a product.
The heating temperature is not particularly limited as long as the synthetic resin or peat moss is not deteriorated, but is usually preferably about 100 ° C to 130 ° C.

The pressure at the time of pressing is 100 g / cm ² to
About 1000 g / cm ² is preferable, and 150 g / cm ² -5
About 00 g / cm ² is more preferable. That is, if the pressure is too low, there is a risk that molding may not be possible depending on the mixing ratio, and if the pressure is too high, it is not possible to secure sufficient water retention by destroying the multilayer structure of the montmorillonite clay mineral, and it becomes too dense. There is a possibility that workability may be impaired.

Although the support member is not particularly limited,
A cement-based material or a wood-based material is usually used, and is disposed so as to straddle between the edges of the adjacent planting base material as in claim 2, and the edge of the planting base material is placed between the planting surface and the planting surface. As if sandwiched between
A structure for fixing to the planting surface by the fixing means, wherein the rail-shaped support members having grooves are arranged in parallel along the planting surface at predetermined intervals so that the grooves face each other, as in claim 3. Then, it is preferable to adopt a structure in which the edge of the plant base material is supported by facing the inside of the groove of the support member.

According to a fourth aspect of the present invention, in the structure of the second or third aspect, the edge of the planting base material is cut out in a substantially stepped or tapered cross section, and at least a part of the support member is cut off. It is preferable that the support member is fitted into the notch and the surface of the support member is flush with the surface of the planting base material or enters inside the surface of the planting base material.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
The details will be described with reference to the drawings. FIG. 1 shows a first embodiment of a planting structure of a planting substrate according to the present invention.

As shown in FIG. 1, the planting base material 1 used in this planting structure has a notch 11 cut out in a tapered shape.
Are provided at both ends, have a substantially trapezoidal cross-sectional plate shape, crush the montmorillonite-based clay mineral to about 100 mesh pass, and then mix it with peat moss to obtain an acrylic copolymer resin emulsion as a synthetic resin binder. The slurry-like molding raw material obtained by further mixing is poured into a pressing mold, pressed and formed into a plate shape, and then heated and forcedly dried, and each component adjacent to each other via an acrylic copolymer resin is obtained. It is solidified in a state where it is bonded and integrated with a point or a line, and is excellent in shape retention even in a water absorbing state, and is in a porous state.

On the other hand, as shown in FIG.
A notch 11 of the planting base material 1
It has a cross-section substantially trapezoidal cross-section having substantially the same thickness as the planting base material 1 provided with the cutout portions 21 on both sides having the same taper angle as the taper angle of.

In this planting structure, as shown in FIG. 1, the notch 11 of the plant base 1 faces the front side, and the notch of the support member 2 The portion 21 faces the planting surface 3 side, and the cutouts 11 and 21 are arranged alternately along the planting surface 3 such as a wall surface of a building so that the notches 11 and 21 are in close contact with each other. It is structured to be fixed to the planting surface 3. That is, the notch 11 which is the edge of the planting base 1 is sandwiched between the notch 21 of the support member 2 and the planting surface 3, and the planting base 1 is firmly supported and fixed. Is done.

As described above, according to this planting structure, the planting base material 1 is composed of the montmorillonite clay mineral granules and the needle-like crystals of the clay mineral (the fine powder generated when the montmorillonite clay mineral is ground). , Which are considered to be crystallized during forced drying) and peat moss are dispersed and mixed together, and the components are bonded and integrated by dots or lines via an acrylic copolymer resin. Due to the bonding strength of the clay mineral itself and the adhesive strength of the acrylic resin copolymer resin, it has sufficient shape retention and is excellent in handling. Also,
Because of its porous shape, when exposed to water, water penetrates into the interior, the montmorillonite clay mineral granules and needle-shaped crystals absorb water and swell, and peat moss also contains water State. Moreover, the shape is maintained by the adhesive force of the acrylic resin copolymer resin.

Therefore, if the edge is supported by the support member 2, even the vertical planting surface 3 can be firmly supported, and the seed can be sprayed on the porous surface of the planting substrate 1. If the fixing is performed, greening can be achieved even on a vertical surface where greening could not be achieved conventionally. Further, since the planting base material 1 and the support member 2 have substantially the same thickness, the support member 2 does not jump out to the surface, and when the planted plant grows, the support member 2 is hidden by the plant and looks good. Greening can be achieved well.
