Description

本発明は、猪などの害獣の田畑への侵入を防止するための電気柵を設置する場合において 田畑の周囲に張設された裸電線の下方の地表における草類の生長を抑えるために、この張設された裸電線の下方の地表に敷設する電気柵用防草シートに関する。   In order to suppress the growth of grass on the surface below the bare wire stretched around the field in the case of installing an electric fence to prevent the invasion of harmful animals such as moths into the field, the present invention The present invention relates to a weedproof sheet for an electric fence to be laid on the ground surface below the stretched bare wire.

中山間地域の農村地帯では、田畑を荒らす猪等の害獣を電気ショックで撃退するために電気柵が多く使用されている。   In rural areas in hilly and mountainous areas, electric fences are often used to repel pests and other pests that damage fields by electric shock.

この電気柵は図６に示すように、田畑の周囲に打設された電気柵用支柱２に取り付けられた碍子１ａ、碍子１ｂに裸電線３ａ、裸電線３ｂを係止して、裸電線３ａ、裸電線３ｂを田畑の周囲に張設し、その裸電線３ａ、裸電線３ｂを約５０ｍごとに裸電線からなる上下結線４で結線したものである。地表より１段目の裸電線３ｂは地表より約２０ｃｍ程度、２段目の裸電線３ａは裸電線３ｂの上方約２０ｃｍ程度の比較的低い位置に張設されている。そして、この張設された裸電線３ａ、裸電線３ｂに、電池もしくはバッテリー等を電源としている衝撃電圧発生器５より発生された衝撃電圧が印加されている。   As shown in FIG. 6, this electric fence is obtained by locking the bare wire 3a and the bare wire 3b to the insulator 1a and the insulator 1b attached to the support 2 for the electric fence placed around the field, and the bare wire 3a. The bare electric wire 3b is stretched around the field, and the bare electric wire 3a and the bare electric wire 3b are connected by the upper and lower connections 4 made of the bare electric wire every about 50 m. The bare electric wire 3b on the first stage from the ground surface is stretched at a relatively low position, about 20 cm above the ground surface, and about 20 cm above the bare electric wire 3b. An impact voltage generated from an impact voltage generator 5 using a battery or a battery as a power source is applied to the bare bare wire 3a and the bare wire 3b.

田畑に侵入しようとして、この張設された裸電線３ａもしくは裸電線３ｂに接触した猪等の害獣には図６中の矢印のように衝撃電圧発生器５の出力端子６、出力線７、裸電線３ａ、上下結線４、裸電線３ｂ、猪８、地中９、アース棒１０、アース線１１、アース端子１２の順路で衝撃電流が流れ、猪８は電気ショックにより電撃を受け、田畑へ侵入する意欲を失い、侵入をあきらめる。   As shown in the arrows in FIG. 6, an output terminal 6 of the impact voltage generator 5, an output line 7, and a harmful animal such as a moth that is in contact with the stretched bare wire 3 a or bare wire 3 b in an attempt to enter the field. An impact current flows in the route of the bare wire 3a, the vertical connection 4, the bare wire 3b, the saddle 8, the underground 9, the ground rod 10, the ground wire 11, and the ground terminal 12, and the saddle 8 is shocked by an electric shock and goes to Tabata. Losing the will to invade and giving up.

この電気柵において地表より１段目の裸電線３ｂの高さは地表より約２０ｃｍと低いため、裸電線３ｂの下の地表の草類が生長し、この草類が裸電線３ｂ及び裸電線３ａに接触すると 衝撃電流はこの接触した草類を通して地中へ漏電することになる。この漏電は裸電線３ｂまたは裸電線３ａに触れる草類の数が増えるのに略比例して多くなり、そして、漏電が多くなれば多くなるほど衝撃電圧発生器５から裸電線３ａ、裸電線３ｂにかかる衝撃電圧は減少することになる。その結果、猪等の害獣に有効な衝撃電流を与えることができなくなる。   In this electric fence, the height of the bare electric wire 3b in the first stage from the ground surface is about 20 cm lower than the ground surface, so that the grass on the surface below the bare electric wire 3b grows, and this grass is the bare electric wire 3b and the bare electric wire 3a. When it touches, the shock current will leak to the ground through this contacted grass. This leakage increases approximately in proportion to the increase in the number of grasses that touch the bare wire 3b or the bare wire 3a, and as the leakage increases, the impact voltage generator 5 changes the bare wire 3a to the bare wire 3b. Such an impact voltage will decrease. As a result, it becomes impossible to give an effective impact current to a pest or other pest.

したがって、猪等の害獣が裸電線３ｂまたは裸電線３ａに触れると害獣に電気ショックを与えるという電気柵のこの忌避効果を維持するためには、裸電線３ｂまたは裸電線３ａに接触している草類、または、接触しようとしている草類を常に取り除く作業が必要である。このため、従来の電気柵では設置コース上に除草剤を使用することも実施されている。   Therefore, in order to maintain this repelling effect of the electric fence that a harmful animal such as a shark touches the bare wire 3b or the bare wire 3a and gives an electric shock to the harmful animal, contact the bare wire 3b or the bare wire 3a. It is necessary to always remove the grass that is in contact with or that is trying to contact. For this reason, the use of a herbicide on the installation course is also carried out in the conventional electric fence.

しかしながら、近年除草剤の環境への影響や地盤が緩む等の理由で、除草剤を使用しない場合も多く見られる。除草剤を使用しない場合は、草類が生長し、電気柵の裸電線に触れようとする度に草類の刈り払い作業を頻繁に行う必要がある。   However, there are many cases where herbicides are not used in recent years due to the influence of the herbicides on the environment and loose ground. When the herbicide is not used, the grass grows and it is necessary to frequently cut the grass every time it tries to touch the bare wire of the electric fence.

そして、電気柵用支柱付近に生えた草類を刈り払い機により刈り払おうとすれば、その電気柵用支柱に誤って刈り払い機の回転している刃物を当ててしまい、電気柵用支柱を切断または破損させてしまうのが常であるために、電気柵用支柱付近に生えた草類は手作業によって草取りをする必要があり、これには、大変な手間がかかり、作業者の負担が極めて大きいという問題があった。   And, if you try to mow the grass growing near the electric fence post with a mower, you accidentally hit the rotating blade of the mower on the electric fence post, Since it is usually cut or damaged, it is necessary to manually weed the grass that grows near the pole of the electric fence, which takes a lot of labor and burdens the operator. There was a problem that it was extremely large.

この手作業で草取りをするという大変な手間をなくす為、例えば特許文献１に開示されているような、化学繊維の細帯を織って作られた防草シートが使用されている。防草シートは幅約６０ｃｍ〜９０ｃｍ程度、長さは任意である。一般的に幅６０ｃｍ、長さ１００ｍのものがロール状に巻かれたものが市販されている。この防草シートを裸電線の下方の地表に敷設すると防草シートで覆われた地面では長期間草類の成長が抑制される。   In order to eliminate the great labor of weeding by this manual work, for example, a weedproof sheet made by weaving a strip of chemical fiber as disclosed in Patent Document 1 is used. The weedproof sheet has a width of about 60 cm to 90 cm, and the length is arbitrary. Generally, a product having a width of 60 cm and a length of 100 m wound in a roll is commercially available. When this weedproof sheet is laid on the ground surface below the bare electric wire, the growth of grass is suppressed for a long time on the ground covered with the weedproof sheet.

また、本願出願人は、特願２００２−１０６１４２号において、衝撃電流をよく通すため金属線を織り込んだ防草シートを提案している。   In addition, the applicant of the present application has proposed a weedproof sheet in which a metal wire is woven in order to pass an impact current well in Japanese Patent Application No. 2002-106142.

図７は一般的な従来の防草シート３０の平面図であり、 図８は図７中の一部３１の拡大図である。   FIG. 7 is a plan view of a general conventional weedproof sheet 30, and FIG. 8 is an enlarged view of a part 31 in FIG.

この防草シート３０は図８に示すように、ポリプロピレン製の幅約２ｍｍ、厚さ約０．４ｍｍ程度の化学繊維の細帯を縦横に織り込んで形成されたものである。この細帯の色は周囲の景観を損ねないように、また、耐候性を高めるため一般的に黒色系が使用される。この防草シート３０を敷設した地面では長期間にわたって草類の成長が抑制される。   As shown in FIG. 8, this weedproof sheet 30 is formed by weaving vertically and horizontally thin strips of a chemical fiber having a width of about 2 mm and a thickness of about 0.4 mm. A black color is generally used for the color of the strip so as not to damage the surrounding scenery and to improve weather resistance. On the ground on which the grass protection sheet 30 is laid, the growth of grass is suppressed for a long time.

この防草シート３０の敷設施工では、第一工程として、猪等の害獣の侵入が予想される、田畑の周囲の電気柵の裸電線を張設する位置のあぜ道などに、止め杭等でこの防草シートを敷き詰める。第二工程として、直径２０ｍｍ、長さ１ｍ程度の電気柵用支柱を、概略４ｍ間隔でこの防草シートのほぼ中央付近に打設する。第三工程として、この打設された電気柵用支柱に碍子を取り付け、第四に、この碍子に裸電線が係止される。   In the laying construction of this weed protection sheet 30, as a first step, it is expected that an infestation of harmful beasts such as corals, etc. Spread this weedproof sheet. As a second step, electric fence posts having a diameter of about 20 mm and a length of about 1 m are placed in the vicinity of the center of the weedproof sheet at intervals of about 4 m. As a third step, an insulator is attached to the placed electric fence post, and fourth, a bare electric wire is locked to the insulator.

ここで、上記の第二工程で電気柵用支柱を打設する場合、図９に示すように防草シート３０を突き破って打ち立てねばならない。この時、図９のように先端が金属の槍のように鋭く尖った支柱５０であれは、容易に化学繊維の細帯で織られた防草シート３０を突き破ることはできる。   Here, when the electric fence post is driven in the second step, the grass protection sheet 30 must be pierced as shown in FIG. At this time, as shown in FIG. 9, even if the tip 50 is sharp and sharp like a metal ridge, it can easily break through the weedproof sheet 30 woven with a strip of chemical fiber.

しかし、通常、図６に示した電気柵に使用される電気柵用支柱２は、もともとトマト、ナス等の作物が倒れないように使用されるもので、作物に接近して打ち立てられる。そして、作物の接近の地面はよく耕され、フワフワと柔らかくなっている。従って電気柵用支柱２の先端は、槍の様に鋭く尖っている必要はなく、例えば図１０に示すように多少丸みをおびている。   However, the electric fence post 2 used for the electric fence shown in FIG. 6 is normally used so that crops such as tomatoes and eggplants do not fall down, and is set up close to the crops. And the ground on which the crop is approaching is well cultivated and fluffy and soft. Therefore, the tip of the electric fence post 2 does not need to be sharply sharp like a ridge, and is somewhat rounded as shown in FIG. 10, for example.

そしてまた、それらの電気柵用支柱２は、必要以上に鋭く尖っていると、取り扱う人に傷を付けることが予想される。必要以上に先端が尖っていて、人を傷付けたりすると 製造物責任（ＰＬ責任）が問われ問題となる。従って、電気柵用支柱２の先端は最小限度の尖り具合であって、丸みをおびているのが通常である。   And if those electric fence posts 2 are sharply sharpened more than necessary, it is expected that a person who handles them will be damaged. If the tip is pointed more than necessary and the person is injured, the product liability (PL responsibility) will be asked and will be a problem. Therefore, the tip of the electric fence post 2 is usually the minimum sharpness and rounded.

この丸みをおびた電気柵用支柱２を、防草シート３０を敷いた電気柵用の支柱として使用する時、防草シート３０を突き破ることは非常に困難であり、電気柵用支柱２を打ち込もうとすると、電気柵用支柱２の先端に沿って防草シート３０が地面の深い位置まで埋め込まれてしまい、防草シート３０には窪みはできるが穴はあかない。そして防草シート３０は、例えば図１１に示すようにいびつな形になったり、その結果、防草シート３０が引っ張られ 防草シート３０を地面に固定する止め杭等の位置で破れたりするという問題が生じていた。
特開平１０−４２７２０号公報 When this rounded electric fence post 2 is used as an electric fence post with a weedproof sheet 30, it is very difficult to break through the weedproof sheet 30. If it tries to insert, the weedproof sheet 30 will be embedded to the deep position of the ground along the front-end | tip of the electric fence support | pillar 2, and although the dent will be indented, there will be no hole. And the weedproof sheet 30 becomes an irregular shape as shown in FIG. 11, for example, and as a result, the weedproof sheet 30 is pulled and is torn at a position such as a retaining pile that fixes the weedproof sheet 30 to the ground. There was a problem.
JP 10-42720 A

本発明が解決しようとする課題は、猪等の害獣の田畑への侵入を防止するための電気柵に使用され、この電気柵の張設された裸電線の下方の地表に敷設する、草類の生長を抑制するための防草シートであって、敷設された防草シートに打設される先端が丸みをおびた電気柵用支柱であっても、容易に打設することのできる電気柵用防草シートを提供することにある。   The problem to be solved by the present invention is a grass used for an electric fence for preventing an infestation of a pest and other harmful beasts, and laying on a ground surface below a bare electric wire stretched over the electric fence. Electricity that can be installed easily even if it is a post for electric fences with a rounded tip that is placed on the laid grass protection sheet. The purpose is to provide a grass protection sheet for the fence.

前記課題を解決するため、本発明の電気柵用防草シートは、シートの長手方向に沿った化学繊維の細帯の一部を抜いて織り込み、これによって電気柵用支柱を打設するための支柱打設部を形成したものである。   In order to solve the above-mentioned problems, a grassproof sheet for electric fences according to the present invention is a method for pulling out a part of a thin strip of chemical fibers along the longitudinal direction of the sheet and weaving it, thereby placing an electric fence post. A strut placement portion is formed.

すなわち、本発明は、田畑の周囲に裸電線を張設し、この裸電線に衝撃電圧を印加して、害獣の田畑への侵入を防止する電気柵において、その張設された裸電線の下方の地表に敷設する、化学繊維の細帯を織って作られた電気柵用防草シートであって、シートの長手方向に沿った細帯のうちの単数本又は複数本を抜いて織り込み、電気柵用支柱を打設するための支柱打設部を形成したことを特徴とする。   That is, the present invention stretches a bare wire around the field and applies an impact voltage to the bare wire to prevent the infestation of the harmful beast into the field. A weedproof sheet for electric fences made by weaving a strip of chemical fiber to be laid on the lower surface, and weaving out one or more of the strips along the longitudinal direction of the sheet, It is characterized in that a strut placement portion for placing a strut for electric fence is formed.

本発明において、支柱打設部は、シートの幅方向中央部に形成することが好ましく、支柱打設部の両端に位置する細帯の色は、他の細帯とは異なる色とすることが好ましい。   In the present invention, the struts are preferably formed at the center in the width direction of the sheet, and the color of the strips positioned at both ends of the struts may be different from other strips. preferable.

本発明の電気柵用防草シートによれば、シートの長手方向の細帯を抜いて織り込み、その細帯を抜いた部分を電気柵用支柱を打設するための支柱打設部としたことにより、電気柵用支柱の打設が非常に容易で短い時間で電気柵の設置を行うことができる。   According to the herbicidal sheet for electric fences of the present invention, the thin strip in the longitudinal direction of the sheet is pulled out and weaved, and the portion from which the thin strip is pulled out is used as a strut placement portion for placing the electric fence strut Thus, the installation of the electric fence post is very easy and the electric fence can be installed in a short time.

また、本発明の電気柵用防草シートは、長手方向の細帯を抜くだけであるから低価格で製造できる。   In addition, the grass protection sheet for electric fences of the present invention can be manufactured at a low cost because it only removes the strip in the longitudinal direction.

そして、電気柵用防草シートを敷設した範囲の草類の生長が抑えられるため、草類の刈り払いに要する時間と手間が不要になるか、または大幅に削減することができる。   And since the growth of the grass of the range which installed the grass-protection sheet | seat for electric fences is suppressed, the time and effort which are needed for the mowing of grass can be made unnecessary, or it can reduce significantly.

以下、本発明の電気柵用防草シートを、猪等の害獣撃退用電気柵に適用した例によって、本発明の実施の形態を説明する。   Hereinafter, the embodiment of the present invention will be described with reference to an example in which the grass fence sheet for an electric fence according to the present invention is applied to an electric fence for repelling harmful animals such as a fence.

図１は、本発明の電気柵用防草シート２０の平面図であり、図２は図１の電気柵用防草シートの一部２１の拡大図である。   FIG. 1 is a plan view of an electric fence weedproof sheet 20 of the present invention, and FIG. 2 is an enlarged view of a part 21 of the electric fence weedproof sheet of FIG.

本発明の電気柵用防草シート２０は、図１及び図２に示すように、耐候性ポリプロピレン製の幅約２．０ｍｍ、厚さ約０．４ｍｍ程度の細帯２２を縦横に織り込んで形成されたもので、図７及び図８に示した従来の防草シート３０の中央部の長手方向に沿った細帯３２ａ〜３２ｄの４本の細帯を抜いた状態でその他の細帯を織り込んだものに相当する。この長手方向の細帯を抜いた箇所が、電気柵用支柱を打設するための支柱打設部２３となる。   As shown in FIGS. 1 and 2, the electric fence grass protection sheet 20 of the present invention is formed by weaving a strip 22 made of weather-resistant polypropylene and having a width of about 2.0 mm and a thickness of about 0.4 mm. In the state where the four strips of the strips 32a to 32d along the longitudinal direction of the central portion of the conventional weedproof sheet 30 shown in FIGS. 7 and 8 are removed, the other strips are woven. It is equivalent to. The portion from which the narrow strip in the longitudinal direction is removed serves as a strut placement portion 23 for placing the electric fence strut.

細帯２２の色は、全体的には周囲の景観を損なわないよう、また、耐候性を高めるために一般的に黒色系が使用されるが、上述した支柱打設部２３の位置がよく分かるように、支柱打設部２３の両側の細帯２２ａ，２２ｂについては、黒色でなく別の色の例えば銀色の細帯を織り込み、支柱打設部２３の位置がはっきり分かるようにしている。   The color of the narrow band 22 is generally used in black so as not to damage the surrounding landscape as a whole and to improve weather resistance, but the position of the above-mentioned strut placement portion 23 can be understood well. As described above, the narrow strips 22a and 22b on both sides of the strut placement portion 23 are woven with another color, for example, a silver strip, so that the position of the strut placement portion 23 can be clearly seen.

上記実施例では、抜いた細帯は４本であるが、４本に限定するものでなく状況により４本より多い場合もあり少ない場合もある。   In the above embodiment, the number of strips removed is four, but the number is not limited to four, and may be more or less than four depending on the situation.

さらに上記実施例では、幅方向のほぼ中央部の細帯を抜いたが、細帯を抜く位置は、中央部に限定するものでなく適宜自由な位置でよい。ただし、中央部に電気柵用支柱を打設するのが防草効果上最適であるので、中央部の細帯を抜くのが一般的である。   Furthermore, in the above-described embodiment, the narrow band at the substantially central portion in the width direction is removed, but the position at which the narrow band is removed is not limited to the central portion, and may be a free position as appropriate. However, since it is optimal for the herbicidal effect to place an electric fence post in the center, it is common to remove the narrow strip in the center.

以下、本発明の電気柵用防草シート２０を敷設し、電気柵を設置する手順を図３を参照して説明する。   Hereinafter, the procedure of laying the electric fence grass protection sheet 20 of the present invention and installing the electric fence will be described with reference to FIG.

まず、田畑の周囲に電気柵を施工するコースを決定し、この決定された電気柵を施工するコース上に草類が生えているなら、そのコース上の草類を１ｍ程度の幅のラインで刈り払う。電気柵を施工するコース上の草類を刈り払い終えたら、電気柵の施工コースに本発明の電気柵用防草シート２０を図３のように敷いていく。電気柵用防草シート２０は幅６０〜９０ｃｍ程度で長さが約１００ｍ程度あり、図４に示すように反物状に巻かれているので、転がすようにして本発明の電気柵用防草シート２０を敷いてゆく。   First, if you decide on a course to build an electric fence around the field, and grass grows on the course on which the decided electric fence is built, the grass on the course is a line with a width of about 1 m. Mow away. When the grass on the course for constructing the electric fence is cut off, the electric fence grass protection sheet 20 of the present invention is laid on the electric fence construction course as shown in FIG. The electric fence weed sheet 20 has a width of about 60 to 90 cm and a length of about 100 m, and is wound in the shape of a fabric as shown in FIG. 20 will be spread.

次に、図３に示すように、電気柵用防草シート２０のほぼ中央部の支柱打設部２３（この支柱打設部２３は上述のように、その両側の細帯を銀色にしているのでよく目につく。）に電気柵用支柱２を打設する。支柱打設部２３は、上述のように長手方向の細帯を抜いて形成されているので、図５に示すように電気柵用支柱２は支柱打設部２３を容易に突き抜けて打設することができ、これによって、電気柵用防草シート２０は仮固定される。   Next, as shown in FIG. 3, the strut placement part 23 (this strut placement part 23 is made of silver on both sides of the strut placement part 23 as described above). The fence 2 for the electric fence is driven in.) Since the strut placement portion 23 is formed by removing the narrow strip in the longitudinal direction as described above, the electric fence strut 2 can easily penetrate the strut placement portion 23 as shown in FIG. Thus, the electric fence grass protection sheet 20 is temporarily fixed.

電気柵用支柱２を打設していく間隔は、現場地形が平坦であれば３ｍ〜５ｍの間隔でよい。電気柵用支柱２が地中に打設される部分の深さは、電気柵用支柱２の長さが本実施例では約１ｍであるので約２５ｃｍ位が理想であるが、地面が硬く電気柵用支柱２が地中に打設される部分の深さが２５ｃｍに満たなくとも 電気柵用支柱２がぐらつかずに、ある程度固定されれば問題ない。   The interval at which the electric fence post 2 is placed may be 3 m to 5 m if the site topography is flat. The depth of the portion where the electric fence post 2 is placed in the ground is ideally about 25 cm since the length of the electric fence post 2 is about 1 m in this embodiment, but the ground is hard and the electric There is no problem as long as the electric fence post 2 does not wobble and is fixed to some extent even if the depth of the portion where the fence post 2 is placed in the ground is less than 25 cm.

全ての電気柵用支柱２を打設し、敷き終えた電気柵用防草シート２０の仮固定を終えた後は、電気柵用防草シート２０を押止し固定するために、電気柵用防草シート２０の幅方向の両端より５ｃｍ程の各位置に止め杭４０を押し込み押止していく。止め杭４０を押止していく間隔は５０ｃｍ〜２ｍと電気柵用支柱２を打設した時ほどに気を配る必要はない。   After all the electric fence posts 2 have been installed and the electric fence weed sheet 20 has been laid temporarily, the electric fence weed sheet 20 is secured and fixed to the electric fence. The stop pile 40 is pushed into each position of about 5 cm from both ends in the width direction of the weedproof sheet 20 and stopped. It is not necessary to pay attention to the interval at which the retaining pile 40 is held down as much as 50 cm to 2 m and when the electric fence post 2 is placed.

ここまでの作業で電気柵用防草シート２０を敷設し終わると、後は通常の電気柵施工方法と同じである。   When the grass fence sheet 20 for the electric fence has been laid by the work so far, the rest is the same as the normal electric fence construction method.

本実施例の猪用電気柵では、打設された電気柵用支柱２に地表より約２０ｃｍの高さに碍子１ｂを取り付け、その碍子１ｂの上方約２０ｃｍの位置に碍子１ａを取り付け、碍子１ａに裸電線３ａを係止し、碍子１ｂに裸電線３ｂを係止し裸電線を田畑の周囲に張設する。   In the fence electric fence of the present embodiment, the insulator 1b is attached to the placed electric fence post 2 at a height of about 20 cm from the ground surface, and the insulator 1a is attached to the position of about 20 cm above the insulator 1b. The bare electric wire 3a is engaged with the insulator 1b, the bare electric wire 3b is engaged with the insulator 1b, and the bare electric wire is stretched around the field.

上下２段の裸電線３ａと裸電線３ｂは約５０ｍごとに裸電線からなる上下結線４で結線し電気的に接続する。そして、電気柵の衝撃電圧発生器５を据え付け、衝撃電圧発生器５の出力端子６から出ている出力線７を裸電線３ａに電気的に接続し、また、衝撃電圧発生器５のアース端子１２にアース線１１を取り付け、そのアース線１１の先に接続されたアース棒１０を地中９に打ち込む。   The bare electric wire 3a and the bare electric wire 3b in the upper and lower stages are connected by an upper and lower wire connection 4 made up of bare wires every 50 m and are electrically connected. Then, the impact voltage generator 5 of the electric fence is installed, the output wire 7 coming out from the output terminal 6 of the impact voltage generator 5 is electrically connected to the bare wire 3a, and the ground terminal of the impact voltage generator 5 is connected. A ground wire 11 is attached to 12 and a ground rod 10 connected to the tip of the ground wire 11 is driven into the underground 9.

以上の作業で、本発明の電気柵用防草シート２０を用いた電気柵の施工が整い、完了する。本発明の電気柵用防草シートを使用することにより電気柵用支柱の打設が容易で短い時間で設置を完了することができる。   With the above operation, the construction of the electric fence using the electric fence grass protection sheet 20 of the present invention is completed and completed. By using the weedproof sheet for electric fences of the present invention, it is easy to place electric fence posts and the installation can be completed in a short time.

そして、電気柵の裸電線の下方の地表に敷設された電気柵用防草シート２０の下の草類の生長は抑制され、除草が不要となるか、または大幅に削減できる。また、長手方向の細帯を抜いて形成した支柱打設置部２３の下においても 長手方向の細帯と直交する細帯は残存しているので、草類の生長は十分抑制される。   And the growth of the grass under the electric fence weedproof sheet 20 laid on the ground surface below the bare electric wire of the electric fence is suppressed, and weeding becomes unnecessary or can be greatly reduced. In addition, since the strips perpendicular to the longitudinal strip remain even under the strut placement portion 23 formed by removing the strip in the longitudinal direction, the growth of the grass is sufficiently suppressed.

さらに、電気柵用防草シート２０は化学繊維の細帯で織られているので、これを敷設することによって、その部分のぬかるみを防止できる。特に、本実施例のように、化学繊維としてポリプロピレンを使用すると、電気柵用防草シート２０の耐候性・耐久性・耐薬品性が向上するとともに、その表面が滑りにくくなる。   Further, since the electric fence weedproof sheet 20 is woven with a thin strip of chemical fiber, by laying it, the portion can be prevented from becoming muddy. In particular, when polypropylene is used as the chemical fiber as in this embodiment, the weather resistance, durability, and chemical resistance of the electric fence weedproof sheet 20 are improved, and the surface thereof is difficult to slip.

本発明は、電気柵が設置される箇所の地表における草類の生長を抑えるため、地表に敷設される防草シートとして有用である   INDUSTRIAL APPLICABILITY The present invention is useful as a weedproof sheet laid on the ground surface in order to suppress the growth of grass on the ground surface where the electric fence is installed.
