BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solidified vegetation soil for greening panels and a method for solidifying the same.
The present invention relates to a solidifiable vegetation soil for a greening panel and a method for solidifying the vegetation soil that can be satisfactorily greened without falling off of the vegetation soil when the slope is greened.

[0002]

2. Description of the Related Art In recent years, the pollution of the natural environment has become a problem. In order to prevent environmental pollution and maintain a favorable natural environment, slopes and vertical surfaces of roads and buildings are required. Greening has begun. Specifically, put the vegetation soil in the greening panel or greening container, and fix it with holding members such as bark, peat moss, lightweight soil, water supply sheet, etc.
It is known that this is used as a vegetation base and is installed on an inclined surface or a vertical surface of a road, a building, or the like to be greened. When greening is performed by such a method, it is important to fix the cultivation soil because the cultivation soil to be filled into the greening panel is attached to an inclined surface or a vertical surface. In addition, a slope spraying method is also known. In this method, synthetic polymer resin or cement is mixed and sprayed onto peat moss or bark to solidify and cultivate the soil. Furthermore, a soil solidification method combining a hydration coagulant and cement is also known. This is a method of reacting sulphate such as aluminum sulphate, which is widely used as a coagulant, with a cement component to react with a hydrate such as ettrine guide. This is a method of making the soil to aggregate.

[0003]

However, the method of putting vegetation soil into a greening panel or a greening container and fixing it with a holding member as described above is complicated in manufacturing, has low manufacturing efficiency, and cannot be manufactured at low cost. There's a problem. Further, in the above-described slope spraying method, since a hydration coagulant is mixed with the vegetation soil, an alkali component is generated, and this alkali has a problem that plants are weakened. Furthermore, in the soil solidification method combining the hydration coagulant and the cement, the compounding amount of the hydration coagulant and the cement is large, alkali damage, vegetation cultivation of concrete is advanced, it is difficult to moderately solidify or agglomerate, There has been a problem that a low alkali product cannot be obtained at low cost.

Accordingly, the present inventors have studied various problems of the above-mentioned methods, and among them, in order to apply the method to the slope or vertical surface of a road or a building as described above, the vegetation cultivation soil has to be used. It is necessary to solve the problem of falling off.In view of this point, after continuing vegetation on vegetation cultivation soil and focusing on the vegetation method of solidifying and cultivating plants, as a result of continuing research, the greening panel as described above To use it, reduce the amount of hydrating coagulant added to the vegetation soil to prevent alkali damage by the hydration coagulant (cement) added to the vegetation soil, to prevent concrete from becoming vegetative soil and to solidify or It has been found that agglomeration can be realized at low cost under low alkali. Furthermore, in the present invention, the vegetation soil can be solidified by watering or humidification by mixing an aqueous resin that gels with an alkali while reducing the amount of the hydrated coagulant, and the solidified soil has voids in a porous shape. It has been found that the formation of the soil enables the water retention and the air permeability to be improved, and the soil between the soils to be softened allows the soil to be grown for surface greening which can grow without inhibiting the elongation of the root of the plant.

[0005] Therefore, the problem to be solved by the present invention is that the plant cultivation can be satisfactorily cultivated without falling off of the vegetation soil even on an inclined surface or a vertical surface of a road or a building, etc. To provide a solidified vegetation culture soil for greening panels that can obtain the above.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail, but the present invention is not limited to these, and is included without departing from the scope of the present invention. The invention of the solidified vegetation soil for a greening panel according to claim 1 is characterized in that the vegetation soil has a hydration coagulant of 2% by weight to 50% by weight. The vegetation soil used in the present invention may be any of various types.Specifically, organic or inorganic particles, aggregates, fibers of natural or artificially created soil or soil made of inorganic or organic matter are used. Add one or more of bark, peat moss, moss, pulp, rock wool, glass wool, water-absorbing fiber, polymer absorbent resin, etc. consisting of the body, and further add organic fertilizers, compost fertilizers using felling materials or organic fertilizers such as synthetic fertilizers It has been added. Examples of the inorganic cultivation include pearlite, vermiculite, clay ball, and red clay, and examples of the organic cultivation include charcoal. Here, as a supplementary amount, by using compost fertilizer using logging material, a component effective for vegetation and a piece of the logging material create an appropriate space in the cultivated soil to promote rooting.

The hydration coagulant used in the present invention is mixed with the vegetation soil and solidifies the vegetation soil with steam or moisture. The degree of solidification can be adjusted by adding an adjusting material or the like to the hydrated coagulant. Depending on the amount of the hydrating coagulant, the growth space can be expanded if the elongation pressure of the plant roots excels, and it can have a strength that cannot be penetrated by the germination root force of the seeds flying to the surface due to the solidification condition. In this way, a weed control effect can be obtained. In order to provide such a weed control effect, it is not necessary to solidify the entire soil layer, but only the surface layer. As the hydration coagulant, cements such as Portland cement, alumina cement, fly ash cement, blast furnace cement and the like are preferable, and improved cements belonging to these systems include early-strength concrete and low alkali concrete. In addition, substances such as gypsum and lime which increase the molecular weight by binding or taking in moisture can also be used. Portland cement is preferably Portland cement, and alumina cement is preferably alumina cement.
There are quick setting cement and low alkali cement.

The amount of the hydrating coagulant used in the present invention is 1% to 50% by weight based on the vegetation soil, and varies depending on the type of the vegetation soil, but is 2% to 50% by weight. Is 5 to 10%. Additives can be further added to the hydrated coagulant, and desired properties can be obtained by adding additives such as a cement polymer, a setting / setting time adjuster, a foaming agent, and a foaming agent. In the present invention, the hydration coagulant is added to the vegetation soil from the beginning and used as a uniform mixture. It is preferable to apply a high amount of cultivated soil because the solidification efficiency is good and the vegetation cultivated soil is prevented from falling off and vegetation. This method is particularly preferable when plants having low resistance to alkalis are vegetated, and this need is small when succulent plants are used.

In the present invention, the solidification is ensured by adding a hydration coagulant hardening accelerator. This hardening accelerator can be added from the beginning to the hydrated coagulant or sprinkled at the time of watering. Or spraying. In the former, solidification is promoted by applying cement water. When a curing accelerator is used, there is an increase in reaction heat and generation of a high alkali content. As the type of the curing accelerator, inorganic salts include sodium aluminate, sodium carbonate, and sodium silicate; cement minerals include calcium aluminate;
Calcium sulphoaluminate, and in organic systems,
Glycerin, triethanolamine and the like can be mentioned.

The solidified vegetation soil for greening panels according to claim 1, wherein the soil comprises from 50% to 50% by volume. Here, the amount of the soil mixed with the vegetation soil or the inorganic soil or organic soil is 10% to 80% by volume, preferably 30% to 70% by volume.
If the content is less than 10% by volume, the amount of the hydrating coagulant becomes excessive and solidifies too much, which is not preferable for vegetation as vegetation soil. A preferable range particularly suitable for vegetation and without falling of the vegetation soil is 5% by volume to 30% by volume. At least one
The compounding amount of a fertilizer such as a kind of organic fertilizer, compost fertilizer or organic synthetic fertilizer is 1% by volume to 30% by volume, preferably 2% by volume to 20% by volume. When the content is 1% by volume, the effect as a fertilizer is not sufficient, and when it exceeds 30% by volume, vegetation is not preferable. Further, the content of at least one kind of inorganic particles, organic particles, aggregates or fibrous bodies is 5% by volume to 50% by volume, preferably 10% by volume to 30% by volume. If it is less than 5% by volume, it is not preferable in terms of vegetation, and if it exceeds 50% by volume, solidification becomes insufficient. Thus, the present invention is configured as described in claim 2,
Vegetation cultivation soil does not fall off even on an inclined surface or a vertical surface such as a road or a building, and good vegetation can be obtained.

According to a third aspect of the present invention, there is provided the solidified vegetation soil for a greening panel according to the first or second aspect, wherein the vegetation soil further comprises a water retention material. Examples of the water retaining material include, but are not particularly limited to, vermiculite, phenol sponge, water-absorbing fiber, superabsorbent resin, bentonite, diatomaceous earth, bark, peat moss, water moss, pulp, rock wool, glass wool, and the like. . These water retention materials have sufficient water retention for vegetation.

The compounding amount of the thickener or the neutralization accelerator of the hydrated coagulated product is 0.1% by weight to 50% by weight, preferably 0.5% by weight to 5% by weight based on the hydrated coagulant. is there. Hydration coagulation accelerator, compounding amount of thickener or neutralization accelerator of hydration coagulation,
If the amount is less than 0.1% by weight, these effects are scarcely exerted. If the amount is more than 50% by weight, solidification is promoted, which is not suitable for vegetation. As described above, the present invention is configured as described in claim 4, so that the vegetation cultivation soil does not fall off even on an inclined surface or a vertical surface of a road or a building, good vegetation is obtained, and it is inexpensive and easy. Can be installed.

According to a fifth aspect of the present invention, the solidified vegetation soil for greening panels contains 5% of an aqueous resin that gels with an alkali or an aqueous resin that gels with an alkali and an adhesive to the soil.
The solidified vegetation soil for a greening panel according to any one of claims 1 to 4, wherein the vegetation soil is contained in an amount of about 300%. As the aqueous resin that gels with an alkali used in the present invention, an aqueous resin such as polyvinyl alcohol is used, and the aqueous resin that gels with an alkali can be used alone or in combination with an adhesive. Preferably, polyvinyl alcohol and an adhesive are mixed. In the present invention, by containing an aqueous resin that gels with an alkali, the cement component that is a source of alkali is reduced as much as possible, and the aqueous resin that gels with an alkali is gelled by a hydrating coagulant to form a network. It becomes a structure and solidifies the soil to reduce cement runoff. As the adhesive used in the present invention, natural rubber, polyvinyl chloride,
Synthetic rubbers such as polyvinylidene chloride, polyvinyl acetate, polyvinyl alcohol, polyacrylate, polymethacrylate, EVA (ethylene-vinyl acetate copolymer resin), and styrene-butadiene. These may be used alone or in combination of two or more. These can be used in the form of an aqueous solution, an emulsion or the like.

In the present invention, in order to prevent the outflow of cement,
A hydrophilic hydrocarbon compound liquid such as ethylene glycol may be used. The hydrophilic hydrocarbon compound liquid is not only mixed with water of several percent at the time of production, but also absorbs water vapor in the atmosphere due to its hygroscopicity, so that the water content increases. Therefore, the hydrophilic hydrocarbon compound liquid can be aggregated by dropping it under stirring into a mixture of a hydrogen resin containing water-absorbing PVA and an adhesive and a cement having hygroscopicity. . Further, in the present invention, when a water-based resin and an adhesive containing PVA are coated with cement as a core, the water-based resin and the adhesive containing PVA in contact with water gelate and spread to the surrounding soil, and then Fe, Ca, Mg, Zr, K, Ti
Is gelled by the oxide of to obtain a block-like solidified product. Therefore, the soil can be efficiently solidified with a small amount of material. There is also a method of separately fixing to the vegetation soil material by the above method.

In the present invention, the volume of the water-based resin and adhesive containing PVA is reduced by evaporation of water after drying. This creates voids and makes it easier for plant roots to penetrate. Utilizing the poor weather resistance of the water-based resin containing PVA and the adhesive, it is quickly decomposed by sunlight and alkali. From this fact, in the case of plant radicles, the soil is fixed by the power of resin and cement, and the strength of the resin decreases as the roots grow, making it easier for the roots to grow. It has excellent effects. The surfactant may be mixed with the hydrating coagulant.
Alternatively, it can be mixed with water when watering. Normally, cement is fine particles, and even if it is mixed in the vegetation soil, more than half flows out in the first watering. In particular, the surface layer has a strong outflow and almost no cement component remains. For this reason, when the cement is solely mixed, it is impossible to cultivate a greening panel for use in a vertical portion such as a wall.

Further, in the present invention, when an aqueous resin which gels with alkali and a hydration coagulant are used in combination, Fe, Ca, Mg, Zr, K, Ti
Oxide is generated and acts with the synthetic resin which solidifies the gel,
The electrolyte generated during the hydration reaction of the cement with water occurs instantaneously, but it takes several hours to start the hardening of the cement, and the solidification of the cultivated soil takes about 3 hours while being affected by the temperature conditions in ordinary cement. Takes time. Fe, Ca, Mg,
The oxides of Zr, K and Ti include Fe ₃ O ₃ , TiO ₁ ,
There are CaO, MgO, and K ₂ O, and the effect of gelling the resin is an effect of each component, when the value is 0.05% by weight or more with respect to cement.

The present invention relates to the use of a powdered hydrophilic resin which is gelled by oxides of Fe, Ca, Mg, Zr, K and Ti generated from cement in contact with water. As a result, the resin that has been made colloid penetrates into the surrounding soil. When dried, when the resin is again formed into a resin, the resin film is formed and solidified by restraining the periphery. But,
FeCa, Mg, Zr, K, T generated from cement
In the case of using a powdered hydrophilic resin which is gelled by the oxide of i, the powdered hydrophilic resin in contact with water is converted into a colloid and penetrates the surrounding soil, but Fe, Ca, Mg generated from cement there. When the oxides of Zr, Kr, and Ti diffuse in water and cover the colloid, the colloidal resin releases moisture and gels. The gelation has a fibrous or sponge-like appearance, but has a network structure formed of resin between soils immersed in water. In this case, since the solidification time of the cement is slow, first, the soil is fixed with the resin, and then the cement is fixed. Furthermore, the amount of water in the cultivated soil increases due to the immediate effect of the solidification of the cultivated soil and the moisture released from the gelling resin, and the curing of the cement proceeds.

The state of the soil after drying is a structure in which the resin forms a mesh structure between the soils and the cement fixes the soil between the soils, and a solidified body having flexibility is formed. The network structure formed in this way does not inhibit the growth of the plant roots, can improve water retention and air permeability, and can be used without impairing the properties of the water retention material added as cultivation soil and the fiber-based cultivation. Therefore, the advantages of both solidification of the resin and solidification of the cement can be obtained synergistically, and the effect can be sufficiently exhibited with a small amount.

According to a sixth aspect of the present invention, there is provided the solidified vegetation soil for greening panels according to the fifth aspect, wherein the hydration coagulant in the greening panel vegetation soil is alumina cement.

According to a seventh aspect of the present invention, in the hydrating coagulant, the aggregating agent is used in an amount of 0.1 to the solidifying vegetation soil for greening panels.
The solidified vegetation soil for greening panels according to any one of claims 1 to 6, wherein the solidified vegetation soil is blended in an amount of 10% by weight to 10% by weight. Examples of the aggregating agent used in the present invention include alcohol, ethylene glycol, and glycerin in a hydrocarbon solution. In addition, examples of the hydrocarbon oils include vegetable oils, mineral oils, and silicone oils. The compounding amount of the aggregating agent is 0.1% by weight to 10% by weight based on the solidifying vegetation soil for greening panels. Preferably it is 0.5 to 3% by weight. In the case of silicone oil, 0.05 to solidification vegetation soil for greening panels
% By weight to 10% by weight. This aggregating agent has a function of preventing a run-off due to water sprinkling by aggregating by mixing with a hydrating coagulant. For plants, it has the effect of preventing the alkali component generated by the hydration reaction of the hydrating coagulant from affecting the plant roots. From the viewpoint of protecting this plant, it is an alkali protective agent. If the aggregating agent and alkali protective agent remain for a long period of time, vegetation will be adversely affected.
Alternatively, water is sprinkled by mixing with water sprinkling, and after completion of the solidification reaction, the surfactant is activated from the water sprinkling to decompose and flow.
As described above, according to the present invention, favorable vegetation can be obtained without falling of the vegetation soil even on an inclined surface or a vertical surface of a road, a building, or the like.

[0038] The invention of claim 8 is that the mixture of the hydration coagulant and the solidification vegetation soil with the mixing ratio of the components other than the hydration coagulant or the single product is arranged in layers or concentric circles.

A ninth aspect of the present invention is the solidifying vegetation soil for greening panels according to any one of the first to eighth aspects, wherein the vegetation soil contains an alkali protective agent. This alkali protective agent uses the same substance as the aggregating agent. As described above, from the viewpoint of protecting the plant from alkali content, a method of coating the plant may be used. For example, by coating a plant with a hydrophilic but highly hydrophobic liquid material contained in high molecular weight hydrocarbon-based water-soluble such as polyethylene glycol,
A protective effect can be obtained by repelling the alkali generated in the first water spray by the hydrophobic effect.

According to a tenth aspect of the present invention, the root surface protective agent is added in an amount of 0.05% by weight to 5% by weight based on the solidifying vegetation soil for greening panels.
The solidified vegetation soil for a greening panel according to any one of claims 1 to 9, wherein the soil is added by weight%. As the root surface protective agent, iron salts are preferable. These iron salts become oxides such as iron oxide when supplied with water, cover the plant roots, and can protect the plant roots from alkalis and reducing substances. At the roots rooted in the optimum soil, the plant itself does not protect the surface, but in soils where anaerobic or harmful substances are present, the root surface protection is an important issue. There is no term “root surface protective agent” for plants in relation to the conventional greening medium, and in the specification of the present invention, the meaning of the root surface protective agent is as follows:
According to the literature, "This flooding occurs when plants are flooded by floods. The roots sink into the water, so aerobic conditions with sufficient oxygen to anaerobic conditions with less oxygen are available. Because aerobic respiration does not occur sufficiently, ethyl alcohol, malic acid, etc. accumulate.Ethyl alcohol is harmful, and flooding can cause the soil to be in a reduced state and produce harmful substances to plants. Rice escapes the harm of these harmful substances by forming a layer of iron oxide around the roots, so if the soil in the rice field contains less iron, the rice is more prone to root rot. " Used for The vegetation soil for greening panels is an artificial environment far away from natural conditions, and it is necessary to impart resistance to the plants themselves. In particular, for watering, a metal salt is preferable because it can cope with the aerobic / anaerobic environment of the root by humidification and drying.

In the case of iron salts, they come into iron oxide when they come into contact with water. When the iron oxide covers the root surface, the root can be protected from harmful substances generated during anaerobic treatment. In the case of copper salts, penetration of alkali can be prevented. Although the stopping power varies depending on the type of plant and environmental conditions, the same salts are preferable for protecting the roots in greening soil in an artificial environment. These metal salts are not particularly limited, but need to have a property of reacting with water at least in the range of pH 5 to 9 to become oxides and reduced products. The metal salts may be added to the solidifying vegetation soil for greening panels from the beginning, or may be added in a solid or liquid form after watering.

Further, the ionic surfactant includes a cationic surfactant, an anionic surfactant and a benign surfactant. The surfactant may be mixed with the hydrating coagulant. Alternatively, it can be mixed with water when watering. Although preferred surfactants are not particularly limited, examples of anionic surfactants include sodium alkylbenzene sulfonate, alkyl sulfate, sodium alkene sulfonate, alkyl ether sulfonate, and dialkyl sulfosuccinic acid. Examples of the nonionic surfactant include polyoxyethylene alkyl ether and polyoxyethylene alkyl allyl ether. Further, a reactive surfactant is also preferably used, and is commercially available from Daiichi Kogyo Seiyaku Co., Ltd. under the trade name of Aqualon RN20, Aqualon RN30, Aqualon HS10 and the like.

Example 2 When vegetation was applied to a greening panel, the proportion of the solidified vegetation soil was varied between the upper layer and the lower layer as described below.

By volume ratio Lower layer Upper layer Perlite 3 3 Vermiculite 3 3 Peat moss 1 Pulp 21 Sand 20 Hydrating coagulant and aggregating agent (alumina cement 7: granulated with glycerin 3) 2 Vegetable seedlings are hydrated In order to protect the plant roots from the alkali content of the coagulant, a product obtained by immersing the plant in an edible oil, which is a hydrocarbon-based oil, to remove the excess oil content was used as an alkali protection agent. Vegetable seedlings are put into the vegetation panel, and the lower layer compound soil is put in. The upper layer compound soil is put in the upper part and water is sprinkled to solidify the solidifying vegetation soil for the greening panel. After half a day, a 1% by weight aqueous solution of anionic surfactant and water were alternately applied three times to the aggregated upper layer compost, and this compost was aggregated to a cultivated state without affecting growth. Decomposing agent and alkali protecting agent could be decomposed. In addition, free alkali generated by this watering is eluted, and the alkalinity decreases. Example 3 In the case where the ground of a plant is used for the purpose of weed control, an acidic substance, for example, a chemical fertilizer (ammonium sulfate, salt and the like) is sown on the ground to reduce alkali content. On top of that, a solidified cultivation soil for vegetation with an upper layer composition is applied in a thickness of 2 to 10 cm, and water is sprinkled. The soil was solidified and the roots could pass, but the shoots could not penetrate due to residual alkalinity and drying. Such vegetation soil can be greened by sowing a plant that is resistant to alkali and drying, such as a succulent plant.
