Description
本発明は、猪や鹿などの指定管理鳥獣による農地や土構造物への有害行動を防止し、指定管理鳥獣が移動する方向を誘導するための方向誘導装置に関する。 The present invention relates to a direction guidance device for preventing harmful behavior of designated controlled birds and animals such as wild boars and deer to farmland and earth structures, and for guiding the direction of movement of designated controlled birds and animals.
近年、平野の外縁部から山間地までの中山間地域において、人口の減少や生活スタイルの変化に伴い、耕作放棄地の増加や山林原野の利用放棄が広がり、環境の変化が進んでいる。このような環境が変化した中山間地域は、猪や鹿などの大型獣に餌、隠れ場所、水などを提供する生息適地となるため、大型獣の生息数および生息分布域が拡大している。大型獣の増加は、農地での食害や人への被害（噛みつき、寄生虫など）、堤防や土手、盛り土などの土構造物に対する棄損などのさまざまな問題をもたらしている。 In recent years, environmental changes are progressing in middle and mountainous areas, from the outer edges of plains to mountainous areas, as the population declines and lifestyles change, resulting in an increase in abandoned cultivated land and widespread abandonment of the use of forests and fields. Hilly and mountainous areas, where the environment has changed, have become suitable habitats for large animals such as wild boars and deer, providing food, shelter, water, etc., resulting in an expansion of the population and distribution area of large animals. . The increase in large animals is causing a variety of problems, including feeding damage to farmland, damage to humans (biting, parasites, etc.), and damage to earth structures such as embankments, embankments, and embankments.
特に、土構造物では、法面の植物の根および昆虫（幼虫）を猪が捕食するために掘り返すなどの有害行動が増加している。法尻部は、斜面安定上極めて重要な部分であり、この部分の緩みは斜面崩壊の危険度を増加させる。また、同様な理由から、猪により石垣を壊される被害も発生している。 In particular, harmful behaviors such as wild boars digging up plant roots and insects (larvae) on slopes in order to prey on earthen structures are increasing. The toe of the slope is an extremely important part for slope stability, and looseness in this part increases the risk of slope failure. For similar reasons, wild boars have also caused damage to stone walls.
このような大型獣による被害の拡大を防止するため、農林水産省および環境省では、従来の鳥獣保護法を改正した新たな鳥獣保護管理法において、猪および鹿を適正規模に捕獲可能な指定管理鳥獣として駆除を進めているが、その結果、新たな捕獲区域となった山奥に生息していた猪が都市部に活動範囲を移動させたことから、生息頭数は減少しているものの農業分野以外の被害は拡大している。 In order to prevent the spread of damage caused by such large animals, the Ministry of Agriculture, Forestry and Fisheries and the Ministry of the Environment have amended the previous Wildlife Protection Act to implement designated management methods that allow the capture of wild boars and deer in appropriate amounts. We are currently exterminating them as wild animals, but as a result, wild boars that used to live in the mountains, which have become a new hunting area, have moved to urban areas, so although the number of wild boars has decreased, they are now being exterminated outside the agricultural field. The damage is increasing.
従来、農地や土構造物などの保護領域内に対する指定管理鳥獣の侵入を防止するため、各種の侵入防止対策が施されている。例えば、従来の侵入防止対策には、金属フェンスや合成樹脂製のネットなどで保護領域内を囲んで指定管理鳥獣の侵入を防止するもの（例えば、特許文献１、２参照）や、センサーライトや蓄光機能を有する合成樹脂製のネットから放射される光、電気ショックなどを利用して指定管理鳥獣に不快感や恐怖感を与えて保護領域への侵入を防止するもの（例えば、特許文献３、４参照）、罠などで指定管理鳥獣を駆除するもの（例えば、特許文献５参照）などが知られている。 Conventionally, various intrusion prevention measures have been taken to prevent designated controlled birds and animals from entering protected areas such as farmland and earthen structures. For example, conventional intrusion prevention measures include enclosing a protected area with a metal fence or synthetic resin net to prevent the intrusion of designated controlled birds and beasts (for example, see Patent Documents 1 and 2), sensor lights, etc. A device that uses light emitted from a synthetic resin net with a luminescent function, electric shock, etc. to give a sense of discomfort or fear to designated managed birds and animals to prevent them from entering a protected area (for example, Patent Document 3, 4), and methods for exterminating designated controlled birds and beasts using traps (for example, see Patent Document 5).
従来の侵入防止技術は、農業被害防止を目的としたものが多く、農作物を目の前にした空腹の猪から設備が破壊されないだけの強固な設備としなければならないため、その設置に多額の費用や手間を必要とするだけではなく、金属フェンスやネットの破損状況の確認や、電気ショックを与えるための電気設備のメンテナンスなど、ランニングコストの負担が大きい。また、従来の侵入防止対策は、その設置コストが大きいことから、指定管理鳥獣に設備を破損された場合の被害額も大きくなってしまう。さらに、大がかりな設備は、人や車両の移動に制約がかかる、という問題もある。 Conventional intrusion prevention technology is often aimed at preventing agricultural damage, and requires a large amount of money to install because the equipment must be strong enough to prevent it from being destroyed by hungry boars in front of the crops. Not only does this require a lot of time and effort, but the running costs are high, such as checking for damage to metal fences and nets, and maintaining the electrical equipment used to deliver electric shocks. In addition, since the installation cost of conventional intrusion prevention measures is high, the amount of damage incurred when the equipment is damaged by designated controlled birds and beasts is also large. Another problem is that large-scale facilities place restrictions on the movement of people and vehicles.
また、猪の侵入防止機能を高めるための高電圧等の強い刺激は、鳥獣***となるだけではなく、人の接触による重大災害（死亡災害）となるおそれがある。 In addition, strong stimulation such as high voltage to enhance the function of preventing wild boar intrusion may not only result in cruelty to wild animals, but also lead to serious disasters (fatal accidents) due to human contact.
さらに、近年では、堤防や盛り土などの土構造物だけではなく、岩盤や砕石盛土、コンクリート面部などの硬い地盤を掘り返し、落石や土砂崩れを引き起こす被害も急増しており、硬い地盤への侵入防止策を求めるニーズが高まっている。同様に、傾斜面や藪地など環境が厳しい場所にも侵入防止策を施す必要がある。 Furthermore, in recent years, not only earth structures such as embankments and embankments, but also hard ground such as bedrock, crushed stone embankments, and concrete surfaces have been dug up, resulting in a rapid increase in damage caused by falling rocks and landslides. There is a growing need for Similarly, it is necessary to take measures to prevent intrusion in places with harsh environments such as slopes and bushes.
一方、授産施設においては障害者にとって実施可能な作業が限られること等から、極めて安い工賃で作業が請け負われるケースも多く、障害者だからという理由で自治体が定めた最低労働賃金さえも支払われず、障害者の保護者が将来に大きな不安を抱えている等の社会問題が発生している。 On the other hand, in vocational facilities, the work that people with disabilities can perform is limited, so there are many cases where the work is contracted out at extremely low wages, and even the minimum wage set by the local government is not paid because the person is disabled. Social problems are occurring, such as parents of people with disabilities having great anxiety about their future.
そこで本発明は、上記課題を解決するために、低コストで指定管理鳥獣の侵入を防止でき、かつ、多様な場所に設置可能な指定管理鳥獣の方向誘導装置を提供することを目的とする。 SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide a direction guidance device for designated birds and beasts that can prevent the invasion of designated birds and beasts at a low cost and can be installed in a variety of locations.
上記課題を解決するために、請求項１の発明は、指定管理鳥獣の侵入を防止するために配置されるネットで、端部が筒状に巻かれたカール部を有することで、前記カール部以外の部分が地面から所定高さだけ上方に配置される防護ネットと、伸縮変形自在な紐状で、前記防護ネットのカール部内に配設され、両端部が前記カール部の端部から突出する支持紐と、打撃することで地中に打ち込み可能なアンカーと、を備え、前記支持紐の両端部に前記アンカーを連結して、前記アンカーを地中に打ち込むことで、前記防護ネットが地面に設置される、ことを特徴とする指定管理鳥獣の方向誘導装置である。 In order to solve the above problem, the invention of claim 1 is a net arranged to prevent the intrusion of designated managed birds and beasts, and has a curled part whose end part is wound into a cylindrical shape. A protective net whose other parts are arranged above the ground by a predetermined height, and a string-like elastically deformable string disposed within a curled portion of the protective net, with both ends protruding from the end of the curled portion. The protection net is provided with a support string and an anchor that can be driven into the ground by striking, and by connecting the anchors to both ends of the support string and driving the anchors into the ground, the protective net can be driven into the ground. This is a direction guidance device for designated managed birds and animals that is installed.

請求項３の発明は、請求項１に記載の方向誘導装置において、前記支持紐が複数の前記防護ネットのカール部内に配設され、前記支持紐が各前記カール部に接続されている、ことを特徴とする。 According to a third aspect of the present invention, in the direction guiding device according to the first aspect, the support string is disposed within the curled portions of the plurality of protective nets, and the support string is connected to each of the curled portions. It is characterized by
請求項４の発明は、請求項１から３に記載の方向誘導装置において、前記支持紐の両端部に２ヵ所以上の結束により環状の連結部が形成され、前記連結部内に前記アンカーを挿入することで前記支持紐の両端部に前記アンカーが連結される、ことを特徴とする。 According to a fourth aspect of the invention, in the direction guidance device according to any one of claims 1 to 3, an annular connecting portion is formed by binding at two or more places at both ends of the support string, and the anchor is inserted into the connecting portion. Accordingly, the anchor is connected to both ends of the support string.
請求項５の発明は、請求項１から４に記載の方向誘導装置において、前記アンカーは、棒状で一端側に尖端部が設けられ地中に打ち込まれるアンカー本体と、前記アンカー本体の他端部を覆うキャップと、を備える、ことを特徴とする。 According to a fifth aspect of the present invention, in the direction guiding device according to any one of claims 1 to 4, the anchor includes an anchor body that is rod-shaped and has a pointed end at one end and is driven into the ground, and the other end of the anchor body. and a cap covering the.
請求項６の発明は、請求項１から５に記載の方向誘導装置において、前記防護ネットの網目は、前記指定管理鳥獣の足が挿入可能で、かつ、前記網目から前記指定管理鳥獣の足を抜こうとする際に前記足に引っ掛かる大きさに設定されている、ことを特徴とする。 The invention according to claim 6 is the direction guidance device according to claims 1 to 5, in which the mesh of the protection net is capable of inserting the foot of the designated bird or animal under management, and the foot of the designated bird or beast can be inserted through the mesh. It is characterized in that the size is set so that it gets caught on the foot when trying to pull it out.
指定管理鳥獣として指定されている猪や鹿などの偶蹄目は、足の先端に２本の主蹄と、そのやや上の後ろ側に２本の副蹄とを有し、これら主蹄や副蹄の間に物が挟まり、あるいは足自体が挟まる可能性があるものを嫌う習性がある。また、猪や鹿は、自分の前足は見えるが後ろ足は見えないため、後足を下ろす位置は自分では意識してコントロールすることができない。 Artiodactyls, such as wild boars and deer, which are designated as designated controlled birds and animals, have two main hooves at the tips of their feet and two secondary hooves on the rear side slightly above the main hooves. They tend to dislike things that get stuck between their hooves, or anything that might get their feet caught between them. Additionally, boars and deer can see their front legs but not their hind legs, so they cannot consciously control where they place their hind legs.
そして、請求項１に記載の発明によれば、地面から所定高さに防護ネットが配置されているため、本装置に猪や鹿が侵入した場合に、前足が防護ネットの網目に挿入されて絡まり、足が曲げられバランスを崩す等の現象を高い確率で経験することになる。また、主蹄や副蹄に防護ネットが挟まることにより、猪や鹿に不快感を与えることもできる。仮に、前足が無事に侵入して着地できたとしても、死角であり意識して着地場所をコントロールできない後足は、前足より更に高い確率で防護ネットに絡まり、主蹄および副蹄の間に防護ネットが挟まることになる。従って、地面から所定高さだけ上方の位置に、防護ネットを設置するという非常に簡易な構成でありながら、保護領域内への指定管理鳥獣の侵入を効果的に防止し、その保護領域外に指定管理鳥獣の移動方向を誘導することができる。 According to the invention described in claim 1, since the protective net is arranged at a predetermined height from the ground, if a boar or deer enters the device, its front legs will be inserted into the mesh of the protective net. There is a high probability that you will experience phenomena such as getting entangled, bending your legs, and losing your balance. Furthermore, if the protective net gets caught between the main hoof and the secondary hoof, it can cause discomfort to boars and deer. Even if the front feet are able to enter and land safely, the hind feet, which are in a blind spot and cannot consciously control where they land, are more likely to get tangled in the protective net than the front feet, and are protected between the main and secondary hooves. The net will get caught. Therefore, although it has a very simple configuration of installing a protective net at a predetermined height above the ground, it can effectively prevent designated managed birds and beasts from entering the protected area, and can prevent designated birds and animals from entering the protected area. It is possible to guide the movement direction of designated managed birds and beasts.
また、防護ネットの端部を筒状に巻いたカール部だけで、その他の部分を地面から所定高さだけ上方に配置するため、構成が簡易となり、製作費や保守費などを低減することが可能となる。しかも、防護ネット自体を加工してカール部を形成するだけであり、他の部材を要しないため、部材費を削減できるとともに、容易かつ短時間で設置することが可能となる。さらに、カール部の大きさ（筒径）を変えるだけで、容易かつ適正に防護ネットを所望の高さに位置させることができる。また、防護ネットの端部を筒状に巻くだけであるため、カール部を授産作業で製作することが可能である。 In addition, since only the curled part of the end of the protective net is placed into a cylindrical shape, and the other parts are placed above the ground at a predetermined height, the configuration is simplified and production and maintenance costs can be reduced. It becomes possible. Moreover, the curled portions are simply formed by processing the protective net itself, and no other members are required, so that the cost of members can be reduced and installation can be done easily and in a short time. Furthermore, the protective net can be easily and appropriately positioned at a desired height by simply changing the size (cylinder diameter) of the curled portion. Furthermore, since the end portion of the protective net is simply rolled into a cylindrical shape, the curled portion can be manufactured by hand-crafting.
一方、伸縮変形自在な支持紐がカール部内に配設され、その両端部にアンカーを連結してアンカーを打撃して地中に打ち込むだけで、防護ネットを設置することができる。このため、岩盤や砕石盛土などの硬い地盤、あるいは、傾斜面や藪地など環境が厳しい場所など、多様な場所に容易、迅速かつ適正に防護ネットを設置することが可能となる。 On the other hand, the protective net can be installed by simply connecting an expandable and deformable support cord to the curled portion, connecting anchors to both ends of the cord, and driving the anchor into the ground. Therefore, it is possible to easily, quickly, and appropriately install the protective net in a variety of locations, such as hard ground such as bedrock or crushed stone embankment, or locations with harsh environments such as slopes and bushes.
また、支持紐が伸縮変形自在なため、防護ネットに足を絡めた指定管理鳥獣がもがいたとしても、支持紐が伸縮したり変形したりして復元するだけであり、足が防護ネットから抜けにくい。この結果、保護領域内への指定管理鳥獣の侵入をより効果的に防止することが可能になるとともに、支持紐さらには本装置の破損、損壊を防止、抑制することが可能となる。 In addition, because the support strings are elastic and deformable, even if a designated controlled bird or animal with its feet entangled in the protective net struggles, the support strings will simply expand, contract, or deform and restore its original shape, allowing its feet to be removed from the protective net. Hard to come off. As a result, it becomes possible to more effectively prevent the designated controlled birds and beasts from entering the protected area, and it also becomes possible to prevent and suppress damage to the support string and also to the present device.
請求項２に記載の発明によれば、支持紐が防護ネットのカール部に接続され、防護ネットと支持紐とが予め一体化されているため、防護ネットつまり本方向誘導装置をより容易、迅速かつ適正に設置することが可能となる。しかも、支持紐をカール部に接続するだけであるため、作業が容易で授産作業で製作することが可能である。 According to the invention described in claim 2, the support string is connected to the curled portion of the protective net, and the protective net and the support string are integrated in advance, so that the protective net, that is, the main direction guidance device can be operated more easily and quickly. And it becomes possible to install it appropriately. Moreover, since the support string is simply connected to the curled portion, the work is easy and can be manufactured by hand-picking.
請求項３に記載の発明によれば、支持紐が複数の防護ネットの各カール部に接続され、複数の防護ネットが支持紐を介して予め一体化されているため、複数の防護ネットをより容易、迅速かつ適正に設置することが可能となる。特に、傾斜面や藪地など設置環境が厳しい場所では作業が困難であるが、このような場所でも容易、迅速かつ適正に設置することが可能で、作業者の負担を軽減することが可能となる。 According to the invention described in claim 3, the support string is connected to each curl part of the plurality of protective nets, and the plurality of protective nets are integrated in advance via the support string, so that the plurality of protective nets can be connected more easily. It becomes possible to install easily, quickly and appropriately. It is particularly difficult to work in places with harsh installation environments such as slopes or bushes, but even in such places it can be installed easily, quickly and properly, reducing the burden on workers. Become.
請求項４に記載の発明によれば、伸縮変形自在な支持紐に引っ張り力が作用し支持紐の断面収縮により結束力が弱まり固定端部が解けてしまうことがなくなり、防護ネットつまり本方向誘導装置をより確実に設置することが可能となる。 According to the invention described in claim 4, a tensile force acts on the expandable and deformable support string, and the cross-sectional contraction of the support string prevents the binding force from weakening and the fixed ends from unraveling, and the protective net, that is, the main direction guidance. It becomes possible to install the device more reliably.
請求項５に記載の発明によれば、アンカーがアンカー本体とキャップとを備えるだけの簡易な構成なため、製作費や保守費を低減可能である。しかも、アンカー本体の他端部がキャップで覆われるため、アンカー本体の他端部で人や指定管理鳥獣が傷つくのを防止することができ安全である。 According to the invention set forth in claim 5, since the anchor has a simple configuration that only includes an anchor body and a cap, manufacturing costs and maintenance costs can be reduced. Moreover, since the other end of the anchor body is covered with a cap, it is possible to prevent the other end of the anchor body from injuring people and designated controlled animals and animals, thereby ensuring safety.
請求項６に記載の発明によれば、防護ネットの網目の大きさが適正なサイズに設定されているため、指定管理鳥獣の足を確実に引っ掛けて絡めることができる。 According to the invention set forth in claim 6, since the size of the mesh of the protection net is set to an appropriate size, it is possible to reliably catch and entangle the legs of designated managed birds and animals.
以下、この発明を図示の実施の形態に基づいて説明する。 The present invention will be described below based on the illustrated embodiments.
図１から図８は、この発明の実施の形態を示し、図１は、この実施の形態に係る指定管理鳥獣の方向誘導装置（以下、「方向誘導装置」という）１を複数設置した状態を示す斜視図である。この方向誘導装置１は、例えば、山の道路際の傾斜面１０１の下部のコンクリート面部１０２に沿うように設置されている。猪Ｍや鹿などの指定管理鳥獣は、傾斜面１０１に生息するミミズや、植生する草木などを捕食するために傾斜面１０１に出没し、傾斜面１０１を掘り返す。このため、方向誘導装置１は、指定管理鳥獣の傾斜面１０１への侵入を防止して、指定管理鳥獣の移動方向を保護領域である傾斜面１０１以外の場所へ誘導するものである。ここで、この実施の形態では、指定管理鳥獣が猪Ｍの場合について、主として以下に説明する。 1 to 8 show an embodiment of the present invention, and FIG. 1 shows a state in which a plurality of direction guidance devices (hereinafter referred to as "direction guidance devices") 1 for designated management birds and beasts according to this embodiment are installed. FIG. This direction guidance device 1 is installed, for example, along a concrete surface portion 102 at the bottom of a slope 101 near a mountain road. Designated controlled birds and animals such as wild boars M and deer appear on the slope 101 and dig up the slope 101 in order to prey on earthworms and plants growing on the slope 101. For this reason, the direction guiding device 1 prevents the designated controlled birds and beasts from entering the slope 101, and guides the designated controlled birds and beasts to a place other than the slope 101, which is a protected area. Here, in this embodiment, the case where the designated managed bird and beast is a boar M will be mainly described below.
この方向誘導装置１は、図２に示すように、主として、防護ネット２と、支持紐３と、アンカー４と、を備える。 As shown in FIG. 2, this direction guiding device 1 mainly includes a protective net 2, a support string 3, and an anchor 4.
防護ネット２は、図３に示すように、猪Ｍの侵入が防止される保護領域またはその近傍、この実施の形態では、コンクリート面部１０２に略横方向に延びて配置されるネット・網体で、端部にカール部２１を有することで、カール部２１以外の部分が地面Ｇから所定高さだけ上方に配置されるものである。すなわち、塑性変形自在な合成樹脂製の網で、略長方形に形成され、図４に示すように、中央部２２が盛り上がった緩やかなアーチ状・円弧状に形成され、その両端部にカール部２１が形成されている。つまり、略長方形の網体の対向する２つの長辺にカール部２１が形成され、カール部２１間がアーチ状に形成されている。 As shown in FIG. 3, the protective net 2 is a net or mesh body that is placed in or near a protected area where the intrusion of the wild boar M is prevented, and in this embodiment extends substantially laterally on the concrete surface 102. By having the curled portion 21 at the end, the portion other than the curled portion 21 is placed above the ground G by a predetermined height. That is, the mesh is made of plastically deformable synthetic resin and is formed into a substantially rectangular shape.As shown in FIG. is formed. That is, the curled portions 21 are formed on two opposing long sides of the substantially rectangular net body, and the space between the curled portions 21 is formed in an arch shape.
このカール部２１は、カール部２１以外の部分を地面Ｇから所定高さだけ上方に位置させるものであり、防護ネット２の端部を円筒状に巻いて形成されている。また、カール部２１の大きさ、外径は、地面Ｇからカール部２１以外の部分が少なくとも所定高さだけ上方に位置するように設定され、この結果、中央部２２の高さＨは、所定高さよりも高くなっている。ここで、所定高さは、図５に示すように、猪Ｍが防護ネット２に足Ｍ１を踏み入れた際に、より確実に猪Ｍの足Ｍ１を捉えられる高さに設定されている。 The curled portion 21 is such that the portion other than the curled portion 21 is positioned above the ground G by a predetermined height, and is formed by winding the end portion of the protective net 2 into a cylindrical shape. Further, the size and outer diameter of the curled portion 21 are set such that the portion other than the curled portion 21 is located above the ground G by at least a predetermined height, and as a result, the height H of the central portion 22 is set to a predetermined height. It is taller than the height. Here, the predetermined height is set to a height that allows the foot M1 of the boar M to be captured more reliably when the boar M steps into the protective net 2, as shown in FIG.
また、防護ネット２の網目２ａは、図６に示すように、猪Ｍの足Ｍ１が挿入可能で、かつ、網目２ａから猪Ｍの足Ｍ１を抜こうとする際に防護ネット２が足Ｍ１に引っ掛かる大きさに設定されている。詳しくは後述するが、例えば１辺が２～５ｃｍの正方形、長方形に形成されている。なお、網目２ａの形状は、正方形、長方形以外の多角形でもよいし、三角形、円形または楕円形であってもよい。 Further, as shown in FIG. 6, the mesh 2a of the protective net 2 is such that the foot M1 of the boar M can be inserted thereinto, and when the foot M1 of the boar M is to be removed from the mesh 2a, the protective net 2 is inserted into the foot M1. The size is set so that it can be caught on. The details will be described later, but for example, it is formed into a square or rectangle with each side measuring 2 to 5 cm. Note that the shape of the mesh 2a may be a polygon other than a square or a rectangle, or may be a triangle, a circle, or an ellipse.
支持紐３は、伸縮変形自在な紐状で、防護ネット２のカール部２１内に配設され、両端部がカール部２１の端部から突出するものであり、この実施の形態では、４つ（複数）の防護ネット２のカール部２１内に配設されている。すなわち、ゴム紐で構成され、防護ネット２に足Ｍ１を絡めた猪Ｍがもがいたとしても、破断することなく支持紐３が伸縮変形し、かつ、足Ｍ１が防護ネット２から抜けにくいように、ゴム紐の伸縮性、弾性変形性および粘性が設定されている。そして、図２に示すように、カール部２１が同軸になるように４つの防護ネット２が配設された状態で、双方の４つ並びのカール部２１を貫通して支持紐３が配設されている。 The support string 3 is in the form of a string that is expandable and deformable, and is disposed within the curled portion 21 of the protective net 2, with both ends protruding from the end of the curled portion 21. In this embodiment, there are four supporting strings. It is disposed within the curled portion 21 of (a plurality of) protective nets 2. In other words, even if the boar M, which is composed of a rubber cord and has its foot M1 entangled in the protective net 2, struggles, the support cord 3 will expand and contract without breaking, and the foot M1 will not easily come off from the protective net 2. The elasticity, elastic deformability, and viscosity of the rubber string are set. Then, as shown in FIG. 2, with the four protective nets 2 arranged so that the curled parts 21 are coaxial, the support string 3 is arranged to pass through both the four-rowed curled parts 21. has been done.
このような支持紐３が各防護ネット２のカール部２１に予め接続されている。すなわち、この実施の形態では、図７に示すように、カール部２１の網目２ａから第１の結束バンド５１の一端側がカール部２１内に挿入され、支持紐３に巻き付いてカール部２１外に引き出されて、第１の結束バンド５１が締め付けられることで、支持紐３がカール部２１に接続、固定されている。このような接続が、各防護ネット２のカール部２１に対して複数箇所で行われ、これにより、支持紐３を介して４つの防護ネット２が連結、一体化されている。つまり、この実施の形態では、４つの防護ネット２が一体の方向誘導装置１を構成している。ここで、第１の結束バンド５１による接続位置と接続数および第１の結束バンド５１の大きさ（幅、厚み）は、防護ネット２に足Ｍ１を絡めた猪Ｍがもがいたとしても、支持紐３と各防護ネット２との接続が破壊されないように設定されている。 Such a support string 3 is connected to the curl portion 21 of each protective net 2 in advance. That is, in this embodiment, as shown in FIG. 7, one end of the first binding band 51 is inserted into the curled part 21 through the mesh 2a of the curled part 21, wrapped around the support string 3, and released outside the curled part 21. By pulling out and tightening the first binding band 51, the support string 3 is connected and fixed to the curled portion 21. Such connections are made at a plurality of locations on the curled portions 21 of each protective net 2, thereby connecting and integrating the four protective nets 2 via the support strings 3. That is, in this embodiment, four protective nets 2 constitute an integrated direction guidance device 1. Here, the connection position and number of connections by the first binding band 51 and the size (width, thickness) of the first binding band 51 are such that even if the boar M struggles with his leg M1 entangled in the protective net 2, The connection between the support string 3 and each protection net 2 is set so as not to be broken.
また、支持紐３の両端部は、図２に示すように、両端に配設された防護ネット２のカール部２１の端部から突出し、２ヵ所以上の結束により環状の連結部３１が形成されている。すなわち、図８に示すように、支持紐３の端部が折り返されて、重ね合わせ部が第２の結束バンド５２と第３の結束バンド５３で固定されることで、環状の連結部３１が形成されている。ここで、連結部３１の環内の大きさ（内径）は、後述するアンカー４のアンカー本体４１を挿入可能で、アンカー４のキャップ４２から抜けないように設定されている。また、この実施の形態では、２つの結束つまり結束バンド５２、５３で連結部３１を形成しているが、３つ以上の結束バンドで形成してもよい。 Further, as shown in FIG. 2, both ends of the support string 3 protrude from the ends of the curled portions 21 of the protective net 2 disposed at both ends, and an annular connecting portion 31 is formed by binding at two or more places. ing. That is, as shown in FIG. 8, the end portion of the support string 3 is folded back and the overlapped portion is fixed with the second binding band 52 and the third binding band 53, so that the annular connecting portion 31 is It is formed. Here, the size (inner diameter) of the inside of the ring of the connecting part 31 is set so that an anchor main body 41 of the anchor 4 described later can be inserted therein, and does not come off from the cap 42 of the anchor 4. Further, in this embodiment, the connecting portion 31 is formed by two binding bands 52 and 53, but it may be formed by three or more binding bands.
アンカー４は、打撃することで地中に打ち込み可能な打ち込み杭で、図８に示すように、アンカー本体４１とキャップ４２とを備える。アンカー本体４１は、鋼鉄製の丸棒体（鉄筋状）で地中に打ち込まれ、一端側に尖端部４１ａが形成されているとともに、外周面から突出する環状のリブ４１ｂが軸方向に沿って所定間隔で複数形成されている。これにより、リブ４１ｂがコンクリート面部１０２などに食い込んでアンカー本体４１が抜けにくいようになっている。ここで、アンカー本体４１の外径、長さおよび強度、剛性は、コンクリート面部１０２や岩盤、砕石盛土などの硬い地盤にも打ち込め、防護ネット２に足Ｍ１を絡めた猪Ｍがもがいたとしても、アンカー本体４１が抜けないように設定されている。 The anchor 4 is a driven pile that can be driven into the ground by impact, and includes an anchor body 41 and a cap 42, as shown in FIG. The anchor body 41 is a round steel rod (reinforcing bar shape) that is driven into the ground, and has a pointed end 41a formed at one end, and an annular rib 41b protruding from the outer peripheral surface along the axial direction. A plurality of them are formed at predetermined intervals. This makes it difficult for the ribs 41b to bite into the concrete surface portion 102 and the anchor body 41 to come off. Here, the outer diameter, length, strength, and rigidity of the anchor body 41 are such that it can be driven into hard ground such as the concrete surface part 102, bedrock, and crushed stone embankment. Also, the anchor body 41 is set so as not to come off.
キャップ４２は、アンカー本体４１の他端部（反尖端部４１ａ）を覆うプラスチック製の蓋である。すなわち、上部が塞がった円筒状で、アンカー本体４１の他端部を圧入できるようになっている。また、上部は大径で丸みを帯びた団子状に形成され、人や指定管理鳥獣が当たっても傷つかないようになっている。 The cap 42 is a plastic lid that covers the other end (the opposite end 41a) of the anchor body 41. That is, it has a cylindrical shape with a closed top, and the other end of the anchor body 41 can be press-fitted therein. In addition, the upper part has a large diameter and is shaped like a rounded dumpling, so that it will not be damaged even if it is hit by a person or designated controlled wildlife.
そして、支持紐３の連結部３１内にアンカー本体４１を挿入することで、支持紐３の端部にアンカー４が連結される。このようにして、支持紐３の両端部にアンカー４を連結して、アンカー４つまりアンカー本体４１を尖端部４１ａ側から地中に打ち込むことで、防護ネット２が支持紐３を介して地面Ｇに設置される。その後、アンカー本体４１の他端部にキャップ４２を取り付けることで、安全性が確保される。 Then, by inserting the anchor body 41 into the connecting portion 31 of the support string 3, the anchor 4 is connected to the end of the support string 3. In this way, by connecting the anchors 4 to both ends of the support string 3 and driving the anchor 4, that is, the anchor body 41 into the ground from the tip 41a side, the protective net 2 is connected to the ground ground via the support string 3. will be installed in Thereafter, safety is ensured by attaching the cap 42 to the other end of the anchor body 41.
次に、このような構成の方向誘導装置１の作用および、方向誘導装置１による指定管理鳥獣の方向誘導方法（以下、「方向誘導方法」という）について説明する。 Next, the operation of the direction guidance device 1 having such a configuration and the direction guidance method for designated management birds and animals using the direction guidance device 1 (hereinafter referred to as "direction guidance method") will be explained.
まず、図１に示すように、コンクリート面部１０２に必要数の方向誘導装置１を設置する。すなわち、一体化された４つの防護ネット２のカール部２１を地面Ｇに当てて配置することで、地面Ｇから所定高さだけ上方の位置に、略横方向に延びるように防護ネット２を配置する。次に、各支持紐３の連結部３１内にアンカー４のアンカー本体４１の尖端部４１ａ側を挿入し、尖端部４１ａを地面Ｇに当ててアンカー本体４１の他端部・上部をハンマーなどで打撃して、アンカー本体４１を地中に打ち込み、一体化された４つの防護ネット２を地面Ｇに配設、固定する。その後、各アンカー本体４１の他端部にキャップ４２を取り付ける。このようにして必要数の方向誘導装置１を必要な個所に設置する。ここで、図１では、方向誘導装置１の幅方向（短尺方向）に３つの方向誘導装置１を並列した状態を図示しているが、幅方向に１つまたは２つ、あるいは４つ以上の方向誘導装置１を配設したり、長手方向（長尺方向）に複数の方向誘導装置１を並列したりしてもよい。 First, as shown in FIG. 1, a required number of direction guidance devices 1 are installed on the concrete surface section 102. That is, by placing the curled portions 21 of the four integrated protective nets 2 against the ground G, the protective net 2 is placed at a position above the ground G by a predetermined height so as to extend substantially laterally. do. Next, insert the pointed end 41a side of the anchor main body 41 of the anchor 4 into the connecting part 31 of each support string 3, put the pointed end 41a against the ground G, and then press the other end and upper part of the anchor main body 41 with a hammer or the like. The anchor body 41 is driven into the ground by striking, and the four integrated protection nets 2 are arranged and fixed on the ground G. Thereafter, a cap 42 is attached to the other end of each anchor body 41. In this way, the required number of direction guidance devices 1 are installed at the required locations. Here, although FIG. 1 shows a state in which three direction guidance devices 1 are arranged in parallel in the width direction (short direction) of the direction guidance device 1, one, two, or four or more direction guidance devices 1 are arranged in parallel in the width direction (short direction). The direction guidance device 1 may be arranged, or a plurality of direction guidance devices 1 may be arranged in parallel in the longitudinal direction (longitudinal direction).
このようにして方向誘導装置１を配設した状態で、猪Ｍは、傾斜面１０１に生息するミミズや、植生している草木を捕食するために傾斜面１０１やコンクリート面部１０２に出没する。そして、図５に示すように、猪Ｍがコンクリート面部１０２に足Ｍ１を踏み入れると、足Ｍ１は防護ネット２の網目２ａに挿入される。図６に示すように、猪Ｍの偶蹄目の足Ｍ１は、先端に２本の主蹄Ｍ１ａを有し、主蹄Ｍ１ａの後方上部には、軟質の膨張部Ｍ１ｂを有する。また、膨張部Ｍ１ｂの上部には、２本の副蹄Ｍ１ｃが存在する。 With the direction guidance device 1 disposed in this manner, the boar M appears on the slope 101 and the concrete surface 102 in order to prey on earthworms living on the slope 101 and plants growing on the slope 101. Then, as shown in FIG. 5, when the boar M steps foot M1 onto the concrete surface portion 102, the foot M1 is inserted into the mesh 2a of the protective net 2. As shown in FIG. 6, the artiodactyl foot M1 of the boar M has two main hooves M1a at the tip, and has a soft expanded portion M1b at the rear upper part of the main hoof M1a. Moreover, two accessory hooves M1c are present at the upper part of the expansion part M1b.
足Ｍ１が挿入された防護ネット２は、網目２ａが副蹄Ｍ１ｃの上部で絡まり、主蹄Ｍ１ａの間や、足Ｍ１と副蹄Ｍ１ｃとの間などに挟まる。猪Ｍは、主蹄Ｍ１ａや副蹄Ｍ１ｃの間に物が挟まったり、足Ｍ１自体が挟まる可能性があるものを嫌う習性があるため、防護ネット２から足Ｍ１を抜こうとして足Ｍ１を上げ下ろししたりする。しかしながら、防護ネット２は、足Ｍ１の膨張部Ｍ１ｂに引っ掛かり、主蹄Ｍ１ａや副蹄Ｍ１ｃに挟まっているため、足Ｍ１は容易に防護ネット２から抜けることはない。このため、猪Ｍに対する不快な状態が維持され、猪Ｍは、傾斜面１０１などへの侵入を諦めて移動方向を変更するものである。 In the protective net 2 into which the foot M1 is inserted, the mesh 2a is entangled with the upper part of the secondary hoof M1c, and is caught between the main hoof M1a or between the foot M1 and the secondary hoof M1c. Boar M has a habit of hating things that get caught between the main hoof M1a and secondary hoof M1c, or anything that might get the leg M1 itself caught, so the boar M raises and lowers the leg M1 in an attempt to remove the leg M1 from the protective net 2. I do things. However, the foot M1 does not easily come out of the protective net 2 because the protective net 2 is caught on the expanded portion M1b of the foot M1 and is sandwiched between the main hoof M1a and the secondary hoof M1c. Therefore, the uncomfortable state for the boar M is maintained, and the boar M gives up on entering the slope 101 and changes its direction of movement.
以上のように、この方向誘導装置１および方向誘導方法によれば、地面Ｇから所定高さに防護ネット２が配置されているため、本装置１に猪Ｍが侵入した場合に、足Ｍ１が防護ネット２の網目２ａに挿入されて絡まり、足Ｍ１が曲げられバランスを崩す等の現象を高い確率で経験することになる。また、主蹄Ｍ１ａや副蹄Ｍ１ｃに防護ネット２が挟まることにより、猪Ｍに不快感を与えることもできる。仮に、前足Ｍ１が無事に侵入して着地できたとしても、死角であり意識して着地場所をコントロールできない後足Ｍ１は、前足Ｍ１より更に高い確率で防護ネット２に絡まり、主蹄Ｍ１ａおよび副蹄Ｍ１ｃの間に防護ネット２が挟まることになる。従って、地面Ｇから所定高さだけ上方の位置に、防護ネット２を設置するという非常に簡易な構成でありながら、保護領域内への指定管理鳥獣の侵入を効果的に防止し、その保護領域外に指定管理鳥獣の移動方向を誘導することができる。しかも、防護ネット２の網目２ａの大きさが適正なサイズに設定されているため、猪Ｍの足Ｍ１などを確実に引っ掛けて絡めることができる。 As described above, according to the direction guidance device 1 and the direction guidance method, since the protective net 2 is arranged at a predetermined height from the ground G, when the boar M enters the device 1, the foot M1 is There is a high probability that the user will experience phenomena such as being inserted into the mesh 2a of the protective net 2 and becoming entangled, causing the leg M1 to bend and causing loss of balance. Furthermore, the protection net 2 being caught between the main hoof M1a and the secondary hoof M1c can also make the boar M feel uncomfortable. Even if the front foot M1 were to successfully enter and land, the hind foot M1, which is in a blind spot and cannot consciously control its landing place, would have an even higher probability of getting entangled in the protective net 2 than the front foot M1, causing the main hoof M1a and secondary foot M1 to become entangled. The protective net 2 will be sandwiched between the hooves M1c. Therefore, although the protection net 2 has a very simple configuration in which the protection net 2 is installed at a predetermined height above the ground G, it is possible to effectively prevent designated managed birds and animals from entering the protected area, and to protect the protected area. It is possible to guide the movement direction of designated managed birds and beasts. Furthermore, since the size of the mesh 2a of the protective net 2 is set to an appropriate size, it is possible to reliably catch and entangle the foot M1 of the boar M.
また、防護ネット２の端部を筒状に巻いたカール部２１だけで、その他の部分を地面Ｇから所定高さだけ上方に配置するため、構成が簡易となり、製作費や保守費などを低減することが可能となる。しかも、防護ネット２自体を加工してカール部２１を形成するだけであり、他の部材を要しないため、部材費を削減できるとともに、容易かつ短時間で設置することが可能となる。さらに、カール部２１の大きさ（筒径）を変えるだけで、容易かつ適正に防護ネット２を所望の高さに位置させることができる。また、防護ネット２１の端部を筒状に巻くだけであるため、カール部２１を授産作業で製作することが可能である。 In addition, since only the curled portion 21, which is the end of the protective net 2 wound into a cylindrical shape, and the other portions are placed above the ground G by a predetermined height, the configuration is simplified and manufacturing and maintenance costs are reduced. It becomes possible to do so. Moreover, since the curled portion 21 is simply formed by processing the protective net 2 itself, and no other members are required, the cost of the members can be reduced and installation can be done easily and in a short time. Furthermore, by simply changing the size (cylinder diameter) of the curled portion 21, the protective net 2 can be easily and appropriately positioned at a desired height. Furthermore, since the end portion of the protective net 21 is simply rolled up into a cylindrical shape, the curled portion 21 can be manufactured by hand-crafting.
一方、伸縮変形自在な支持紐３がカール部２１内に配設され、その両端部にアンカー４を連結してアンカー４を打撃して地中に打ち込むだけで、防護ネット２を設置することができる。このため、岩盤や砕石盛土などの硬い地盤、あるいは、傾斜面や藪地など環境が厳しい場所など、多様な場所に容易、迅速かつ適正に防護ネット２を設置することが可能となる。しかも、アンカー４は硬い地盤に打ち込み可能なため、堤防や盛り土などの土構造物だけではなく、コンクリート面部１０２や砕石盛土などの硬い地盤にも防護ネット２を設置して、猪Ｍなどの侵入を防止することが可能となる。 On the other hand, a support string 3 that is expandable and deformable is disposed within the curled portion 21, and the protective net 2 can be installed by simply connecting anchors 4 to both ends of the support string 3 and driving the anchors 4 into the ground. can. Therefore, it is possible to easily, quickly and appropriately install the protective net 2 in various places such as hard ground such as bedrock or crushed stone embankment, or places with harsh environments such as slopes and bushes. Moreover, since the anchors 4 can be driven into hard ground, the protective net 2 can be installed not only on earth structures such as embankments and embankments, but also on hard ground such as concrete surfaces 102 and crushed stone embankments, to prevent intrusion such as wild boars M. This makes it possible to prevent
また、支持紐３が伸縮変形自在なため、防護ネット２に足Ｍ１を絡めた猪Ｍがもがいたとしても、支持紐３が伸縮したり変形したりして復元するだけであり、足Ｍ１が防護ネット２から抜けにくい。この結果、傾斜面１０１内への指定管理鳥獣の侵入をより効果的に防止することが可能になるとともに、支持紐３さらには本装置１の破損、損壊を防止、抑制することが可能となる。 In addition, since the support string 3 is expandable and deformable, even if the boar M with its foot M1 entangled in the protective net 2 struggles, the support string 3 will only expand and contract or deform and recover, and the foot M1 will be restored. is difficult to escape from the protective net 2. As a result, it becomes possible to more effectively prevent the designated controlled birds and beasts from entering into the slope 101, and it also becomes possible to prevent and suppress damage to the support string 3 and further to the device 1. .
また、支持紐３が防護ネット２のカール部２１に接続され、防護ネット２と支持紐３とが予め一体化されているため、防護ネット２つまり本方向誘導装置１をより容易、迅速かつ適正に設置することが可能となる。しかも、支持紐３を第１の結束バンド５１でカール部２１に接続するだけであるため、作業が容易で授産作業で製作することが可能である。 In addition, since the support string 3 is connected to the curled portion 21 of the protective net 2 and the protective net 2 and the support string 3 are integrated in advance, the protective net 2, that is, the main direction guiding device 1 can be operated more easily, quickly and properly. It becomes possible to install it in Moreover, since the support string 3 is simply connected to the curled portion 21 with the first binding band 51, the work is easy and can be produced by hand-picking.
さらに、支持紐３が複数の防護ネット２の各カール部２１に接続され、複数の防護ネット２が支持紐３を介して予め一体化されているため、複数の防護ネット２をより容易、迅速かつ適正に設置することが可能となる。特に、傾斜面や藪地など設置環境が厳しい場所では作業が困難であるが、このような場所でも容易、迅速かつ適正に設置することが可能で、作業者の負担を軽減することが可能となる。 Furthermore, since the support string 3 is connected to each curl part 21 of the plurality of protective nets 2, and the plurality of protective nets 2 are integrated in advance via the support string 3, it is easier and faster to connect the plurality of protective nets 2. And it becomes possible to install it appropriately. It is particularly difficult to work in places with harsh installation environments such as slopes or bushes, but even in such places it can be installed easily, quickly and properly, reducing the burden on workers. Become.
また、支持紐３の両端部の連結部３１内にアンカー４つまりアンカー本体４１を挿入するだけで、支持紐３の両端部にアンカー４が連結されるため、防護ネット２つまり本方向誘導装置１をより容易、迅速かつ適正に設置することが可能となる。しかも、２ヵ所以上の結束により連結部３１が形成されているため、伸縮変形自在な支持紐３に引っ張り力が作用し支持紐３の断面収縮により結束力が弱まり固定端部が解けてしまうことがなくなり、防護ネット２つまり本方向誘導装置１をより確実に設置することが可能となる。 In addition, the anchors 4 are connected to both ends of the support string 3 by simply inserting the anchors 4, that is, the anchor bodies 41, into the connecting portions 31 at both ends of the support string 3. It becomes possible to install it more easily, quickly and properly. In addition, since the connecting portion 31 is formed by binding at two or more places, a tensile force acts on the expandable and deformable support string 3, and the cross-sectional contraction of the support string 3 weakens the binding force and causes the fixed end to come undone. Therefore, the protective net 2, that is, the main direction guidance device 1 can be installed more reliably.
さらに、アンカー４がアンカー本体４１とキャップ４２とを備えるだけの簡易な構成なため、製作費や保守費を低減可能である。しかも、アンカー本体４１の他端部がキャップ４２で覆われるため、アンカー本体４１の他端部で人や指定管理鳥獣が傷つくのを防止することができ安全である。 Furthermore, since the anchor 4 has a simple configuration that only includes the anchor body 41 and the cap 42, manufacturing costs and maintenance costs can be reduced. Moreover, since the other end of the anchor body 41 is covered with the cap 42, it is possible to prevent the other end of the anchor body 41 from injuring people or designated managed birds and animals, thereby ensuring safety.
以上、この発明の実施の形態を詳述してきたが、具体的な構成はこの実施の形態に限られるものではなく、この発明の要旨を逸脱しない範囲の設計の変更等があっても、この発明に含まれる。例えば、上記の実施の形態では、アンカー本体４１が鉄筋状の棒体で構成されているが、打ち込む地盤などに応じてその他の構成にしてもよい。また、支持紐３の両端部にアンカー４を予め連結、固定して、防護ネット２と支持紐３とアンカー４とを予め一体化してもよい。これにより、環境が厳しい場所でもより容易、迅速かつ適正に方向誘導装置１を設置することが可能となる。さらに、隣接する防護ネット２同士を結束バンドなどで連結してもよく、これにより、防護ネット２の破損、取り外れなどをより防止することが可能となる。 Although the embodiments of this invention have been described in detail above, the specific configuration is not limited to this embodiment, and even if there are changes in the design within the scope of the gist of this invention, Included in invention. For example, in the embodiment described above, the anchor body 41 is made of a reinforcing rod, but other structures may be used depending on the ground into which the anchor is to be driven. Alternatively, the protective net 2, the support string 3, and the anchors 4 may be integrated in advance by connecting and fixing the anchors 4 to both ends of the support string 3 in advance. This makes it possible to install the direction guidance device 1 more easily, quickly and appropriately even in places with harsh environments. Furthermore, adjacent protective nets 2 may be connected to each other with a binding band or the like, thereby making it possible to further prevent the protective nets 2 from being damaged or removed.
