Abstract
Description
本発明は、鉄道、道路、鉄塔、動物防護柵等の電気施設において導電性を付与しつつ、雑草の生育を抑制する防草材及びその使用方法に関する。 The present invention relates to a herbicidal material that suppresses the growth of weeds while imparting conductivity to electrical facilities such as railways, roads, steel towers, and animal protection fences, and a method of using the same.
鉄道、道路、鉄塔、動物防護柵等の電気施設の周囲では雑草が繁茂して電線に接触すると電気が短絡してしまう課題がある。
そこで、頻繁な草刈りや除草剤散布が必要であった。特に、草の刈取りには多大の労力を必要とするため、一般的には除草剤を散布する方法が行われている。
しかしながら、除草剤の散布は、草を枯らすだけで、頻繁に散布する必要があり、抜本的な対策とはならない。また、セメントを含有する防草材を振り撒いて散水して地面を被覆する方法も提案されているが、電気抵抗が高く通電性が要求される箇所においては悪影響を与えてしまう課題があった。例えば、動物防護柵では、電線と地面と動物の間で、地面を通じて一定の通電性がなければ、動物へ電気が流れない。イノシシ等の害獣を追い払える目安として、「和歌山県農作物被害防止対策マニュアル」電気柵設置のポイント では３，５００Ｖ以上の電圧が必要であるとしている。さらに、セメントを含有する防草材は、セメントを含有することでアルカリ性が高く、さらに六価クロムを含有することから、環境影響にも課題があった。
Around electric facilities such as railways, roads, steel towers, and animal protection fences, there is a problem that weeds overgrow and short-circuit electricity when they come into contact with electric wires.
Therefore, frequent mowing and herbicide spraying were necessary. In particular, since a great deal of labor is required for cutting the grass, a method of spraying a herbicide is generally performed.
However, spraying herbicides is not a drastic measure because it needs to be sprayed frequently only by withering the grass. In addition, a method of sprinkling and spraying a herbicidal material containing cement to cover the ground has been proposed, but there is a problem that it has an adverse effect in places where electrical resistance is high and electrical conductivity is required. . For example, in an animal protection fence, electricity does not flow to an animal unless there is a certain level of electrical conductivity between the wire, the ground, and the animal through the ground. As a guideline to remove wild boars and other pests, the Wakayama Prefectural Agricultural Damage Prevention Manual states that a voltage of 3,500V or more is required at the point of electric fence installation. Furthermore, the herbicidal material containing cement has a high alkalinity by containing cement, and also contains hexavalent chromium, and thus has a problem in environmental impact.
さらに、セメントを含まない酸化マグネシウム系固化材を散布、又は土に混合し、散水して固化させて抑草する抑草材とその方法が提案されている。（特許文献１、２、３）
特許文献１は、酸化マグネシウムと高炉スラグを主成分する雑草繁殖防止材を地表面の土と混合して転圧して押し固めて、その上に散水するため、施工に労力を必要とした。また、初期強度発現性が低いため、施工後の降雨で流失し易く、繁殖期の雑草を抑草する効果が低下し易く、さらに導電性が低い課題がある。
特許文献２と３も特許文献１と同様の酸化マグネシウム系固化材であるため、繁殖期の雑草を抑草する効果が低い課題がある。
特許文献４は、土質材、セメント系固化材、団粒化剤を主成分とする防草層であるが、前述したようにセメントを含有することでアルカリ性が高く、さらに六価クロムを含有することから、環境影響にも課題があった。
特許文献５、６、７は、導電性を有する防草シートが提案されている。しかしながら、防草シートは美観に課題があり、さらに雑草を抑草する効果が低下し、定期的な交換に多大な労力を要する。
In addition, a herbicidal material and a method for suppressing it by spraying or mixing a magnesium oxide-based solidified material not containing cement into the soil and watering and solidifying it have been proposed. (Patent Documents 1, 2, and 3)
Patent Document 1 requires labor for construction because a weed reproduction preventing material mainly composed of magnesium oxide and blast furnace slag is mixed with soil on the ground surface, pressed and pressed, and sprinkled on it. Moreover, since initial strength development is low, it is easy to be washed away by rainfall after construction, the effect of suppressing weeds in the breeding season is likely to be reduced, and there is a problem that conductivity is low.
Since Patent Literatures 2 and 3 are the same magnesium oxide-based solidifying materials as Patent Literature 1, there is a problem that the effect of suppressing weeds in the breeding season is low.
Patent Document 4 is a herbicidal layer mainly composed of a soil material, a cement-based solidifying material, and an aggregating agent. However, as described above, it contains a cement and has high alkalinity and further contains hexavalent chromium. As a result, there were also problems with environmental impact.
Patent Documents 5, 6, and 7 propose a weedproof sheet having conductivity. However, the herbicidal sheet has a problem in aesthetics, further reduces the effect of suppressing weeds, and requires a lot of labor for regular replacement.
本発明は、導電性を付与し、草刈の労力を軽減でき、導電性、防草効果の持続性が確保できる防草材及びその使用方法を提供する。 The present invention provides a herbicidal material that imparts electrical conductivity, can reduce the labor of mowing, and can ensure electrical conductivity and sustainability of the herbicidal effect, and a method of using the same.

The calcium aluminate used in the present invention is mainly composed of CaO and Al 2 O 3 obtained by mixing a calcia raw material and an alumina raw material and firing the kiln or melting and cooling in an electric furnace. It is a general term for substances having hydration activity, and can be used in any of crystalline and amorphous materials. It is a material having a fast curing time and high initial strength.

When it exceeds 15% by mass, it takes time to cure, and further, it does not harden at low temperatures and the herbicidal effect may be low. Typical examples of impurities include silicon oxide, other alkali metal oxides, alkaline earth metal oxides, titanium oxide, iron oxide, alkali metal halides, alkaline earth metal halides, alkali metal sulfates, and alkaline earths. There are those in which a similar metal sulfate or the like is substituted for a part of CaO or Al 2 O 3 , but it is not particularly limited.

If it is 70% or less, the initial strength development may be lowered. The vitrification rate of calcium aluminate is preferably 70% or more, more preferably 90% or more in terms of reaction activity. As for the vitrification rate, the main peak area S of the crystalline mineral was measured in advance by a powder X-ray diffraction method for the sample before heating, then heated at 1000 ° C. for 2 hours, and then slowly cooled at a cooling rate of 1 to 10 ° C./min. Then, the main peak area S 0 of the crystal mineral after heating by the powder X-ray diffraction method is obtained, and further, the vitrification rate χ is calculated by using the values of S 0 and S using the following formula. Vitrification rate χ (%) = 100 × (1−S / S 0 )

In terms of strength development, anhydrous gypsum is preferable, and hydrofluoric acid byproduct anhydrous gypsum and natural anhydrous gypsum can be used. The pH when the gypsum is immersed in water is preferably from a weak alkali having a pH of 8 or less to acidic. When the pH is high, the solubility of the gypsum component becomes high, which may inhibit the initial strength development.

Although the usage-amount of gypsum is not specifically limited, 50-250 mass parts is preferable with respect to 100 mass parts of calcium aluminates. If it is less than 50 mass parts, intensity | strength expression will fall and a herbicidal effect may be low. If it exceeds 250 parts by mass, the strength development may be reduced and the herbicidal effect may be low.
本発明では、強度を増進させる目的でカルシウムシリケートを使用できる。
カルシウムシリケートは、３ＣａＯ・ＳｉＯ２や２ＣａＯ・ＳｉＯ２があり、特に限定されるものではないが、γ−２ＣａＯ・ＳｉＯ２が大気中の二酸化炭素を吸収し組織を緻密化させ、防草効果に優れるため、最も好ましい。
γ−２ＣａＯ・ＳｉＯ２は、２ＣａＯ・ＳｉＯ２で表される化合物の中で、低温相として知られるものであり、高温相であるα−２ＣａＯ・ＳｉＯ２やβ−２ＣａＯ・ＳｉＯ２とは異なるものである。これらの化合物はいずれも２ＣａＯ・ＳｉＯ２で同じ化学組成を有するが、結晶構造は異なっている。セメントクリンカ中に存在する２ＣａＯ・ＳｉＯ２はβ−２ＣａＯ・ＳｉＯ２である。β−２ＣａＯ・ＳｉＯ２は水硬性を有するが、本発明におけるγ−２ＣａＯ・ＳｉＯ２は水硬性を持たないが、大気中の二酸化炭素を吸収して硬化する特性があることを見出した。
γ−２ＣａＯ・ＳｉＯ２の粒度は、特に制限されないが、ブレーン比表面積値で３０００ｃｍ２／ｇ以上が好ましく、４，０００〜８，０００ｃｍ２／ｇがより好ましい。ブレーン比表面積値が３，０００ｃｍ２／ｇ未満では、大気中の二酸化炭素を吸収して反応が十分でなく、ひび割れ抵抗性が充分に得られない場合がある。８，０００ｃｍ２／ｇを超えても更なる効果の増進が期待できない。
カルシウムシリケートの使用量は、特に限定されるものではないが、カルシウムアルミネートと石膏の合計１００質量部に対して、１０〜６０質量部が好ましい。１０質量部未満では、強度が低い場合がある。６０質量部を超えると更なる効果の増進が期待できない。
In the present invention, calcium silicate can be used for the purpose of increasing strength.
Calcium silicates include 3CaO · SiO 2 and 2CaO · SiO 2 , and are not particularly limited. However, γ-2CaO · SiO 2 absorbs carbon dioxide in the atmosphere and densifies the tissue, thereby improving the herbicidal effect. Most preferred because of its superiority.
γ-2CaO · SiO 2 is different among the compounds represented by 2CaO · SiO 2, is what is known as low-temperature phase, the α-2CaO · SiO 2 and β-2CaO · SiO 2 is a high temperature phase Is. All of these compounds are 2CaO · SiO 2 and have the same chemical composition, but their crystal structures are different. 2CaO · SiO 2 present in the cement clinker is β-2CaO · SiO 2 . Although β-2CaO · SiO 2 has hydraulic properties, γ-2CaO · SiO 2 in the present invention does not have hydraulic properties, but has been found to have a property of absorbing and curing carbon dioxide in the atmosphere.
The particle size of the γ-2CaO · SiO 2 is not particularly limited but is preferably 3000 cm 2 / g or more in Blaine specific surface area value, 4,000~8,000cm 2 / g is more preferable. When the Blaine specific surface area value is less than 3,000 cm 2 / g, carbon dioxide in the atmosphere is absorbed and the reaction is not sufficient, and crack resistance may not be sufficiently obtained. Even if it exceeds 8,000 cm 2 / g, further enhancement of the effect cannot be expected.
Although the usage-amount of a calcium silicate is not specifically limited, 10-60 mass parts is preferable with respect to a total of 100 mass parts of calcium aluminate and gypsum. If it is less than 10 parts by mass, the strength may be low. If it exceeds 60 parts by mass, further enhancement of the effect cannot be expected.
本発明の防草材において、カルシウムアルミネートと石膏の合計１００質量部に対して、土壌の割合は、特に限定されるものではないが、通常、１００〜１０００質量部が好ましく、２００〜８００質量部がより好ましい。土壌が１００質量部未満では強度発現性は高いが経済的に好ましくない。１０００質量部を超えると強度が低く、防草効果が得られない可能性がある。 In the herbicidal material of the present invention, the proportion of soil is not particularly limited with respect to a total of 100 parts by mass of calcium aluminate and gypsum, but is usually preferably 100 to 1000 parts by mass, and 200 to 800 parts by mass. Part is more preferred. If the soil is less than 100 parts by mass, the strength development is high, but this is not economically preferable. If it exceeds 1000 parts by mass, the strength is low and the herbicidal effect may not be obtained.
本発明で使用する土壌は、砂利、砂、礫、粘土のいずれか１種又は２種以上を含むものでは特に限定されるものではない。山砂、川砂、海砂等のサンド質土壌やシルト質土壌、クレイ質土壌、工事から発生する残土、重量骨材や軽量骨材や再生骨材や防草処理を行う箇所の土をそのまま用いることなどいずれも使用できる。一般には、天然土である真砂土や赤玉土や鹿沼土や山砂、海砂、砕砂などの乾燥砂は品質が安定しており、より好ましい。 The soil used in the present invention is not particularly limited as long as it contains any one or more of gravel, sand, gravel and clay. Sandy soil such as mountain sand, river sand, sea sand, silty soil, clayey soil, residual soil generated from construction, heavy aggregate, lightweight aggregate, reclaimed aggregate, and soil where weeding treatment is used as it is Anything can be used. In general, dry sand such as natural sand, red sand, kanuma soil, mountain sand, sea sand, and crushed sand, which are natural soils, is more preferable because of its stable quality.
水の配合量は、本発明の防草材の合計１００質量部に対して５〜１００質量部が好ましい。５質量部未満では混合が困難となる場合があり、１００質量部を超えると強度が得られない場合がある。 As for the compounding quantity of water, 5-100 mass parts is preferable with respect to a total of 100 mass parts of the herbicidal material of this invention. If it is less than 5 parts by mass, mixing may be difficult, and if it exceeds 100 parts by mass, strength may not be obtained.
本発明では、凝結調整剤を本発明の差し支えない範囲で使用することが可能である。凝結調整剤はセメントの凝結を促進、遅延するものであれば特に限定されるものではない。具体的には、オキシカルボン酸又はその塩、リン酸又はその塩、デキストリン、ショ糖、ポリアクリル酸又はその塩、減水剤、高性能減水剤などを１種又は２種以上、本発明の目的を実質的に阻害しない範囲で使用することが可能である。 In the present invention, it is possible to use a setting modifier within the scope of the present invention. The setting modifier is not particularly limited as long as it accelerates or delays the setting of the cement. Specifically, one or more of oxycarboxylic acid or a salt thereof, phosphoric acid or a salt thereof, dextrin, sucrose, polyacrylic acid or a salt thereof, a water reducing agent, a high-performance water reducing agent, etc. Can be used within a range that does not substantially inhibit.
本発明では、酸化マグネシウムなどの低ｐＨの固化材、ウッドチップ、もみ殻などの嵩をあげる増量材、各種ポルトランドセメント、水酸化カルシウム、塩化カルシウム、石灰石微粉末、フライアッシュ、カオリン、カーボン、アルカリ金属塩、シラス、珪藻土及びシリカフュームなどの混和材料、発泡剤、消泡剤、増粘剤、防錆剤、防凍剤、減水剤、流動化剤、ポリマー、ベントナイトなどの粘土鉱物、ハイドロタルサイトなどのアニオン交換体、着色剤などを１種又は２種以上、本発明の目的を実質的に阻害しない範囲で使用することが可能である。 In the present invention, low pH solidified material such as magnesium oxide, wood chip, bulking agent such as rice husk, various portland cement, calcium hydroxide, calcium chloride, limestone fine powder, fly ash, kaolin, carbon, alkali Admixtures such as metal salts, shirasu, diatomaceous earth and silica fume, foaming agents, antifoaming agents, thickeners, rust preventives, antifreezing agents, water reducing agents, fluidizing agents, polymers, clay minerals such as bentonite, hydrotalcite, etc. These anion exchangers, colorants and the like can be used in a range that does not substantially impair the object of the present invention.
本発明において、各材料の混合方法は、特に限定されるものではなく、それぞれの材料を施工時に混合しても良く、あらかじめ一部を、あるいは全部を混合しておいても差し支えないが、事前に混合し、現場で水を混合するほうが、品質面で好ましい。事前に混合する場合、土壌は乾燥状態であることが好ましい。 In the present invention, the mixing method of each material is not particularly limited, and each material may be mixed at the time of construction, and a part or all of them may be mixed in advance. It is preferable in terms of quality to mix in water and mix water on site. When mixing in advance, the soil is preferably dry.
混合装置としては、既存のいかなる装置も使用可能であり、例えば、傾胴ミキサ、オムニミキサ、２軸強制ミキサ、ヘンシェルミキサ、Ｖ型ミキサ、及びナウタミキサなどの使用が可能である。 As the mixing apparatus, any existing apparatus can be used. For example, a tilting cylinder mixer, an omni mixer, a two-axis forced mixer, a Henschel mixer, a V-type mixer, and a Nauta mixer can be used.
本発明では、地面の雑草を草刈機等で１ｃｍ以下程度に草刈し、刈り取った雑草を取り除いた上に防草材を敷き詰めて散水して被覆する方法。また、練混ぜた防草材を吹き付けて被覆する方法があり、草刈してその後に除草剤を散布してから被覆するとより好ましい。 In the present invention, a method of mowing the weeds on the ground to about 1 cm or less with a mower or the like, removing the cut weeds, spreading a weed proofing material and spraying the water. Moreover, there is a method of spraying and coating a kneaded herbicide, and it is more preferable to cover the grass after cutting and then spraying a herbicide.
防草材を草刈した地面に敷き詰めて、その上に散水して表面を固化させて被覆する場合は、地面に防草材を敷き詰めてならし、その上にジョウロ等で散水する方法が好ましい。敷き詰める厚さは特に限定されるものではなく、地面の凸部で１〜３ｃｍの厚さが好ましい。１ｃｍ以下であると全体に被覆することができにくくなるため、防草効果が低くなる場合があり、３ｃｍ以上では防草効果は高いが材料費が高くなり、多大な労力がかかるため好ましくない。 In the case where the herbicidal material is spread over the ground where the grass is mowed, and the surface is sprinkled to solidify the surface to cover the surface, a method of spreading the herbicidal material over the ground and sprinkling it with a watering device or the like is preferable. The thickness to spread is not particularly limited, and a thickness of 1 to 3 cm is preferable at the convex portion of the ground. If it is 1 cm or less, it becomes difficult to cover the whole, so that the herbicidal effect may be lowered. If it is 3 cm or more, the herbicidal effect is high, but the material cost becomes high, and a great deal of labor is required.
本発明の防草材または、本発明の防草材の土壌を除いたものを草刈した地面に敷設し、地面の土と混合攪拌させて被覆する場合は、バックホウやスタビライザーなどを用いて混合攪拌させることが可能である。さらに転圧をすることで硬い地盤とすることも可能である。 When laying on the ground where the herbicidal material of the present invention or the soil of the herbicidal material of the present invention is mowed and covering it by mixing and stirring with the soil on the ground, mixing and stirring using a backhoe or a stabilizer It is possible to make it. Further, it is possible to make the ground hard by rolling.
以下、本発明の実験例に基づいて説明する。 Hereinafter, description will be made based on experimental examples of the present invention.
「実験例１」
