Description
本発明は、動物侵入防止シート、より詳しくは、防護柵の下方からの動物の侵入を防ぐ動物侵入防止シートに関する。 The present invention relates to an animal intrusion prevention sheet, and more particularly to an animal intrusion prevention sheet that prevents animals from entering from below a protective fence.
周知のとおり、例えば山間地の高速道路等において、道路内への立ち入りや横断等を防ぐため、金網フェンスや格子フェンス等の各種の防護柵が道路に沿って設置されている。ところが、従来、これら防護柵の下方と地面との隙間からタヌキやイノシシ等の野生動物が侵入し、道路内で衝突事故等を引き起こす問題があった。 As is well known, various types of protective fences such as wire mesh fences and lattice fences are installed along the roads, for example on expressways in mountainous areas, in order to prevent people from entering or crossing the roads. However, in the past, there has been a problem in which wild animals such as raccoon dogs and wild boars enter through the gap between the bottom of these protective fences and the ground, causing collisions on the road.
そこで、現在までに、防護柵の下方の隙間を塞いで動物の侵入を防ぐ侵入防止ネットが提案されている（例えば、下記特許文献１、２参照）。この侵入防止ネットは、弾性網状体から構成され、防護柵に装着する際に、網状体自身をほぼ直角に曲げて上方の起立部を防護柵に固定するとともに、下方のスカート部を地面に接地させるものであり、網状体の曲げ弾性を利用してスカート部の接地圧を高めて防護柵の下方からの野生動物の侵入を防ごうとするものである。 Therefore, to date, an intrusion prevention net has been proposed that closes the gap below the protective fence to prevent animals from entering (for example, see Patent Documents 1 and 2 below). This intrusion prevention net is composed of an elastic mesh body, and when attached to a protective fence, the net itself is bent almost at right angles to fix the upper standing part to the protective fence, and the lower skirt part is grounded to the ground. The purpose is to utilize the bending elasticity of the net-like body to increase the ground pressure of the skirt portion to prevent wild animals from entering from below the protective fence.
しかしながら、この従来の侵入防止ネットは、網状体から構成されていたため、防護柵への装着後、スカート部が接地する地面に雑草が繁茂することになり、其処に集まる昆虫やネズミ等の小動物や葛等の蔓性植物の根を餌とするイノシシやタヌキ等によって地面が掘り返され、その結果、スカート部と地面との間に一部隙間が生じ、野生動物の侵入を招く難点があった。 However, since this conventional intrusion prevention net is composed of a net-like material, after it is attached to the protective fence, weeds will grow on the ground where the skirt part touches the ground, and small animals such as insects and rats will gather there. The ground is dug up by wild boars, raccoon dogs, etc. that feed on the roots of vine plants such as kudzu, and as a result, a gap is created between the skirt and the ground, which poses the problem of allowing intrusion by wild animals.
本発明は、従来の侵入防止ネットに上記のような難点があったことに鑑みて為されたもので、防護柵の下方に雑草が繁茂するのを抑制して確実に防護柵の下方からの動物の侵入を防ぐことができる動物侵入防止シートを提供することを課題とする。 The present invention was developed in view of the above-mentioned difficulties with conventional intrusion prevention nets, and it suppresses the growth of weeds under the protective fence and ensures that weeds can be removed from below the protective fence. An object of the present invention is to provide an animal intrusion prevention sheet that can prevent animals from invading.
本発明は、防護柵の下方からの動物の侵入を防ぐ動物侵入防止シートであって、防護柵の下方の地面に敷設される敷設シート部と、前記敷設シート部に接合され、前記防護柵に固定される起立シート部とを備え、前記敷設シート部が防草シート材から成り、
前記敷設シート部と前記起立シート部との接合部において、前記敷設シート部の一の端縁側と前記起立シート部の一の端縁側とが同じ向きに重ねられて接合されていることを特徴としている。
The present invention is an animal intrusion prevention sheet that prevents animals from entering from below a protection fence, and includes a laying sheet part that is laid on the ground below the protection fence, and a sheet that is joined to the laying sheet part and is attached to the protection fence. and a fixed upright sheet part, the laying sheet part being made of a weed control sheet material,
At the joint between the laying sheet part and the standing sheet part, one edge side of the laying sheet part and one edge side of the standing sheet part are overlapped and joined in the same direction. There is.
また、本発明は、前記防草シート材が不織布から成ることを特徴としている。 Further, the present invention is characterized in that the weed control sheet material is made of a nonwoven fabric.
また、本発明は、前記起立シート部がネット材から成ることを特徴としている。 Further, the present invention is characterized in that the upright seat portion is made of a net material.
本発明に係る動物侵入防止シートによれば、防護柵の下方の地面に敷設する敷設シート部が防草シート材から構成されているので、防護柵への装着後、敷設シート部が敷設された地面に葛等の蔓性植物その他の雑草が繁茂するのを抑制することができ、イノシシ等の野生動物が地面を掘り返して敷設シート部と地面との間に隙間が生じるのを未然に防ぐことができ、長期間に亘って確実に動物の侵入を防止することができる。 According to the animal intrusion prevention sheet according to the present invention, since the laying sheet part to be laid on the ground below the protection fence is made of a weed control sheet material, the laying sheet part is laid down after being attached to the protection fence. It is possible to suppress the growth of vine plants such as kudzu and other weeds on the ground, and to prevent wild animals such as wild boars from digging up the ground and creating gaps between the laying sheet part and the ground. This makes it possible to reliably prevent animal intrusion over a long period of time.
図１及び図２に示すように、本実施形態の動物侵入防止シート１０は、防護柵の下方の地面に敷設される敷設シート部１と、この敷設シート部１に接合され、防護柵に固定される起立シート部２とから構成されている。 As shown in FIGS. 1 and 2, the animal intrusion prevention sheet 10 of this embodiment includes a laying sheet part 1 laid on the ground below the protective fence, and a laying sheet part 1 that is joined to the laying sheet part 1 and fixed to the protective fence. It is composed of an upright seat part 2.
敷設シート部１は、長尺帯状の防草シート材から成り、本実施形態では、防草シート材として、ポリエステル長繊維から成る幅６５ｃｍ×長さ２５ｍ×厚み約２ｍｍの柔軟な黒色の不織布を使用している。この不織布は、遮光率９９．５％以上の遮光性を有しており、主に日光等を遮光することによって雑草の成長・繁茂を抑制する。 The laying sheet part 1 is made of a long belt-shaped weed control sheet material. In this embodiment, the weed control sheet material is a flexible black nonwoven fabric made of polyester long fibers with a width of 65 cm x length of 25 m x thickness of approximately 2 mm. I am using it. This nonwoven fabric has a light-shielding property with a light-shielding rate of 99.5% or more, and suppresses the growth and flourishing of weeds mainly by blocking sunlight and the like.
起立シート部２は、長尺帯状のネット材から成り、本実施形態では、ネット材として、幅６０ｃｍ×長さ２５ｍ×厚み約０．６ｍｍの柔軟な灰色のネット材を使用している。このネット材は、ポリエステル繊維から構成され、その表面にポリ塩化ビニールが被覆されており、図３に示すように、一辺約６ｍｍの略正方形状の通孔２１が多数、縦横方向に並んで開設されている。 The upright sheet portion 2 is made of a long belt-shaped net material, and in this embodiment, a flexible gray net material with a width of 60 cm x a length of 25 m x a thickness of about 0.6 mm is used as the net material. This net material is made of polyester fibers and its surface is coated with polyvinyl chloride, and as shown in Fig. 3, a large number of approximately square-shaped holes 21 with each side of about 6 mm are lined up in the vertical and horizontal directions. has been done.
本実施形態の動物侵入防止シート１０は、これら敷設シート部１及び起立シート部２のそれぞれの片側の長辺部のみが互い接合されて構成されている。即ち、図１及び図２に示すように、敷設シート部１と起立シート部２との接合部３において、敷設シート部１の一の端縁１２側と起立シート部２の一の端縁２２側とが同じ向きになるように重ねられて接合されている。 The animal intrusion prevention sheet 10 of this embodiment is constructed by joining only the long sides of each of the laying sheet part 1 and the standing sheet part 2 to each other. That is, as shown in FIGS. 1 and 2, at the joint 3 between the laying sheet part 1 and the standing sheet part 2, one edge 12 side of the laying sheet part 1 and one edge 22 of the standing sheet part 2 They are overlapped and joined so that the sides are facing the same direction.
本実施形態では、敷設シート部１の一の端縁１２と起立シート部２の一の端縁２２とが揃えられた状態で、敷設シート部１と起立シート部２とが本縫いにより縫い合わされて接合されている。図中、符号３１で指示するものは、計二列の縫い目である。 In this embodiment, the laying sheet part 1 and the standing sheet part 2 are sewn together by lock stitching with one edge 12 of the laying sheet part 1 and one edge 22 of the standing sheet part 2 aligned. are joined together. In the figure, what is indicated by the reference numeral 31 is a total of two rows of seams.
図４に示すように、本実施形態の動物侵入防止シート１０を既設の防護柵Ｆに装着する際には、まず、必要に応じて防護柵Ｆの下方の地面Ｇの雑草等を除去して整地した後、敷設シート部１及び起立シート部２を全体に重ねた状態（図１参照）でロール巻きされた動物侵入防止シート１０を、その接合部３を防護柵Ｆ側へ向けて地面Ｇ上に置き、防護柵Ｆに沿って展開し、敷設シート部１で防護柵Ｆの下方の地面Ｇを覆う。このとき、例えば、防護柵Ｆの設置状況等に応じて、敷設シート部１をその幅方向または長さ方向に適宜、切断し、地面Ｇを隙間なく覆う。 As shown in FIG. 4, when attaching the animal intrusion prevention sheet 10 of this embodiment to an existing protection fence F, first remove weeds and the like on the ground G below the protection fence F as necessary. After leveling the ground, place the rolled animal intrusion prevention sheet 10 with the laying sheet part 1 and the standing sheet part 2 overlapped (see Figure 1) on the ground G with the joined part 3 facing the protection fence F side. It is placed on top and spread out along the protective fence F, and the ground G below the protective fence F is covered with the laid sheet part 1. At this time, for example, depending on the installation status of the protective fence F, the laying sheet portion 1 is appropriately cut in the width direction or length direction, and the ground G is covered without any gaps.
次いで、起立シート部２を防護柵Ｆの金網面等に沿って起立させ、起立シート部２を防護柵Ｆに仮止めした後、敷設シート部１の所要位置にアンカーピン４を打ち込んで敷設シート部１を地面Ｇに固定する。打ち込んだアンカーピン４の頭部には、必要に応じて遮光性のテープ４１を貼着する。 Next, the standing sheet part 2 is stood up along the wire mesh surface of the protective fence F, and after temporarily fixing the standing sheet part 2 to the protective fence F, the anchor pins 4 are driven into the required positions of the laying sheet part 1 to secure the laying sheet. Fix part 1 to the ground G. A light-shielding tape 41 is attached to the head of the driven anchor pin 4, if necessary.
そして、仮止めした起立シート部２を公知の結束バンド５を用いて防護柵Ｆの金網や支柱等に固定することによって、既設の防護柵Ｆに動物侵入防止シート１０を装着する。こうして、防護柵Ｆの下方からの野生動物の侵入を防止するのである。 Then, the animal intrusion prevention sheet 10 is attached to the existing protection fence F by fixing the temporarily fastened upright sheet portion 2 to the wire mesh, pillars, etc. of the protection fence F using a known binding band 5. In this way, wild animals are prevented from entering from below the protective fence F.
このように本実施形態の動物侵入防止シート１０は、防護柵Ｆの下方の地面Ｇに敷設する敷設シート部１が防草シート材から構成されているので、防護柵Ｆへの装着後、敷設シート部１が敷設された地面Ｇに葛等の蔓性植物その他の雑草が繁茂するのを抑制することができ、例えばイノシシが大好物の葛の根を求めて地面Ｇを掘り返して敷設シート部１と地面Ｇとの間に隙間が生じるのを未然に防ぐことができ、長期間に亘って確実に動物の侵入を防止することができる。 In this way, in the animal intrusion prevention sheet 10 of the present embodiment, the laying sheet part 1 to be laid on the ground G below the protective fence F is made of a weed control sheet material. It is possible to suppress the growth of vine plants such as kudzu and other weeds on the ground G on which the sheet part 1 is laid. It is possible to prevent a gap from forming between 1 and the ground G, and it is possible to reliably prevent animals from entering for a long period of time.
しかも、本実施形態の動物侵入防止シート１０は、敷設シート部１の一の端縁１２側と起立シート部２の一の端縁２２側とが同じ向きに重ねられて接合されているので、起立シート部２を防護柵Ｆに沿って起立させたとき、この起立シート部２の起立に伴って敷設シート部１の一の端縁１２が持ち上げられて地面Ｇとの間に隙間が生じることもなく、敷設シート部１の一の端縁１２を確実に地面Ｇに接地させることができ、敷設シート部１の全面に亘って有効に雑草の繁茂を抑制することができる。 Moreover, in the animal intrusion prevention sheet 10 of the present embodiment, the one edge 12 side of the laying sheet part 1 and the one edge 22 side of the upright sheet part 2 are overlapped and joined in the same direction. When the erected sheet part 2 is erected along the protective fence F, one edge 12 of the laying sheet part 1 is lifted as the erected sheet part 2 is raised, creating a gap between it and the ground G. Therefore, one edge 12 of the laid sheet part 1 can be reliably brought into contact with the ground G, and the growth of weeds can be effectively suppressed over the entire surface of the laid sheet part 1.
また、このように敷設シート部１の一の端縁１２側と起立シート部２の一の端縁２２側とが同じ向きに重ねられて接合されているので、図１に示すように、接合部３を含め、起立シート部２を敷設シート部１上に隙間なく重ねることができ、よりコンパクトにロール巻きすることができる。したがって、動物侵入防止シート１０の防護柵Ｆへの装着作業性は勿論のこと、その搬送・保管作業性も格段に向上させることができる。 Moreover, since the one edge 12 side of the laying sheet part 1 and the one edge 22 side of the upright sheet part 2 are overlapped and joined in the same direction, as shown in FIG. The upright sheet part 2, including the part 3, can be stacked on the laid sheet part 1 without any gaps, and can be rolled up more compactly. Therefore, not only the workability of attaching the animal intrusion prevention sheet 10 to the protective fence F, but also the workability of transporting and storing it can be significantly improved.
また、本実施形態の動物侵入防止シート１０は、敷設シート部１の防草シート材が不織布から構成されているので、例えば出芽時等の雑草の突き抜けや野生動物の踏み付けにも強く、長期間に亘って雑草の繁茂を抑制することができる。 In addition, in the animal intrusion prevention sheet 10 of this embodiment, the weed prevention sheet material of the laying sheet part 1 is made of non-woven fabric, so it is resistant to penetration by weeds such as when they sprout, and trampling by wild animals, for a long period of time. It is possible to suppress the growth of weeds over a period of time.
また、本実施形態の動物侵入防止シート１０は、起立シート部２が多数の通孔２１を有するネット材から構成されているので、これら通孔２１に結束バンド等を差し通しながら起立シート部２を防護柵Ｆに固定することができ、防護柵Ｆへの装着作業性を向上させることができる。また、これら多数の通孔２１により、起立シート部２の風圧を低減化することができ、長期間に亘って動物の侵入を防ぐことができる。 In addition, in the animal intrusion prevention sheet 10 of this embodiment, the upright sheet portion 2 is made of a net material having a large number of through holes 21, so while inserting a cable tie or the like into these through holes 21, the upright sheet portion 2 can be fixed to the protective fence F, and the workability of attaching the protective fence F to the protective fence F can be improved. Furthermore, the large number of through holes 21 can reduce the wind pressure on the upright seat portion 2, and can prevent animals from entering for a long period of time.
以上、本実施形態の動物侵入防止シートについて説明したが、本発明は他の実施形態でも実施することができる。 Although the animal intrusion prevention sheet of this embodiment has been described above, the present invention can also be implemented in other embodiments.
例えば、上記実施形態では、敷設シート部１と起立シート部２とを縫合により接合しているが、本発明はこれに限定されるものではなく、敷設シート部１と起立シート部２とを例えば接着、溶着、ピン留め等の他の手段により直接的にまたは間接的に接合するようにしてもよい。 For example, in the above embodiment, the laying sheet part 1 and the standing sheet part 2 are joined by stitching, but the present invention is not limited to this, and the laying sheet part 1 and the standing sheet part 2 are connected, for example. They may be joined directly or indirectly by other means such as gluing, welding, pinning, etc.
また、上記実施形態では、敷設シート部１の一の端縁１２と起立シート部２の一の端縁２２とを揃えて接合しているが、例えば、起立シート部２の一の端縁２２を、敷設シート部１の一の端縁１２よりも中寄りの位置に接合してもよい。この接合位置については、装着すべき防護柵の構造や防護柵の設置環境等に応じて種々の設計変更が可能である。また、敷設シート部１及び起立シート部２の形状、サイズについても、状況に応じて種々の設計変更が可能である。 Further, in the above embodiment, one edge 12 of the laying sheet section 1 and one edge 22 of the upright sheet section 2 are aligned and joined, but for example, one edge 22 of the upright sheet section 2 may be joined at a position closer to the middle than one end edge 12 of the laying sheet portion 1. Regarding this joint position, various design changes are possible depending on the structure of the protective fence to be attached, the installation environment of the protective fence, etc. Furthermore, the shapes and sizes of the laying sheet section 1 and the standing sheet section 2 can be changed in various designs depending on the situation.
また、上記実施形態では、敷設シート部１を構成する防草シート材として、高い遮光率を有する不織布を採用しているが、例えば、織布やフィルム材を採用してもよく、また、これらを複数層、積層させた複合シート材を採用してもよい。また、この敷設シート部１を構成する防草シート材は、必ずしも高い遮光率を有している必要はなく、例えば、所定の強度を有し、出芽・成長時等に上方へ伸びようとする雑草を上方から物理的に押さえることよって雑草の繁茂を抑制する防草シート材を採用してもよい。この防草シート材の材質、構造等については、雑草の種類等を含む防護柵の設置環境等に応じて種々の設計変更が可能である。 Further, in the above embodiment, a nonwoven fabric having a high light blocking rate is used as the weed control sheet material constituting the laying sheet part 1, but for example, a woven fabric or a film material may also be used. A composite sheet material made by laminating multiple layers may also be used. Further, the weed control sheet material constituting the laying sheet portion 1 does not necessarily have to have a high light blocking rate, but for example, has a predetermined strength and tends to grow upward during germination, growth, etc. A weed control sheet material that suppresses weed growth by physically suppressing weeds from above may be used. Regarding the material, structure, etc. of this weed control sheet material, various design changes can be made depending on the installation environment of the protective fence including the type of weeds, etc.
