本発明は、害獣侵入防止用構造体および害獣侵入防止方法に関する。詳しくは、シカ、イノシシなどの動物が農作物、山林、法面、斜面などに侵入することで生じる被害を防ぐための害獣侵入防止用構造体および害獣侵入防止方法に関する。 The present invention relates to a structure for preventing a pest infestation and a method for preventing a pest infestation. More particularly, the present invention relates to a pest invading structure and a pest invading prevention method for preventing damage caused by animals such as deer and wild boars invading crops, mountain forests, slopes, slopes and the like.
近年、田畑に植えられた作物、山林に植えられた果物、タケノコなどの食用作物が、侵入してきたシカやイノシシによって食害される問題が拡大してきている。また、高速道路や国道の両側は法面となっていたり、田畑の周囲の道や山道では、道の側面が斜面になっており、これらの法面や斜面を維持するために植物が植生されていたりするケースが多いが、植生されている植物もシカやイノシシによって食害される問題が拡大している。植物が食害されて地面が露出すると、雨などによって地盤が浸食されて法面や斜面が崩れることもある。したがって、シカやイノシシのような害獣の侵入を防止する手段が求められている。 In recent years, food crops such as crops planted in fields, fruits planted in mountain forests, bamboo shoots and the like have been encumbered by eating deer and wild boars. In addition, both sides of expressways and national roads are slopes, and in roads and mountain roads around fields, the sides of roads are slopes, and plants are planted to maintain these slopes and slopes. In many cases, the problem that plants being vegetated are damaged by deer and wild boars is expanding. When plants are eaten away and the ground is exposed, the ground may be eroded by rain and the slope and slope may collapse. Therefore, there is a need for means for preventing the infestation of pests such as deer and wild boars.
田畑、山林、法面や斜面への害獣の侵入を防止する手段としては、目的の土地の周囲に防止柵を設けることが一般的である。様々な種類の防止柵が国や地方公共団体からもマニュアルが提案されている。しかしながら、防止柵は、設置が比較的容易であるものの、害獣のうち、シカやイノシシのような大型の動物が防止柵に接触すると防止柵が変形したり、破損したりする可能性がある。また、法面や斜面のような場所では、防止柵を設けても、法面や斜面の上側から飛び越えて侵入する可能性もある。 As a means to prevent the infestation of pests on fields, forests, slopes and slopes, it is common to provide a guard fence around the target land. Manuals have been proposed for various types of fences from the government and local governments. However, although the prevention fence is relatively easy to install, there is a possibility that the prevention fence may be deformed or damaged when large animals such as deer and wild boars of the harmful animals come in contact with the prevention fence. . In addition, in places such as slopes and slopes, even if a protection fence is provided, there is a possibility of jumping and entering from the upper side of the slopes and slopes.
そこで、獣害防止効果の大きい獣害防御具として、棒状且つ円弧状に形成した複数個の枠部材と、この枠部材の両端を地面に突き刺して前記枠部材を地面に立設した上に展設するネットと、このネットの縁部を地面に固定する複数個の止め具とよりなる獣害防御具が提案されている（特許文献１）。この獣害防御具では、ネットを曲面状または斜面状に展設することにより、ネットを忌避する獣の性質を利用して獣害を防御しており、また、獣がネットを乗り越えようとした場合には、ネットが足に絡みつき乗り越えを困難にしている（特許文献１の段落［０００７］参照。）。
しかしながら、前記害獣防御具は、ネットが枠部材の表面に固定されておらず、複数の枠部材どうしもそれぞれ独立して立設されているため、枠部材間のネットに獣が強く接触すると、ネットが獣に絡みつくことで獣害防御具が破損し、この破損した箇所から別の獣が侵入して獣害が発生する可能性がある。この場合、補修は可能であるものの、獣害防御具が破損していないかを定期的に見回ることが必要となるなど、メンテナンスにも注力する必要がある。
Therefore, a plurality of frame members formed in a rod shape and a circular arc shape and the both ends of this frame member are pierced on the ground to stand the frame members on the ground as a animal damage protective tool having a large animal damage prevention effect. There has been proposed a beast harm defense device comprising a net to be set and a plurality of fasteners for fixing the edge of the net to the ground (Patent Document 1). In this beast damage defense device, by extending the net in a curved surface or slope shape, the nature of the beast repellent to the net is used to protect the beast damage, and the beast tried to get over the net. In the case, the net is entangled in the foot, making it difficult to get over (see paragraph [0007] of Patent Document 1).
However, since the net is not fixed to the surface of the frame member, and the plurality of frame members stand independently of each other, when the beast strongly contacts the net between the frame members, the pest-protecting device is Because the net is entangled in the beast, the beast harm defense equipment may be damaged, and another beast may intrude from the broken part to cause the beast harm. In this case, although repair is possible, it is necessary to focus on maintenance, as it is necessary to regularly look for damage to the animal damage protective equipment.
また、特許文献２の図３に記載のような防獣ネット柵１も提案されている。この防獣ネット柵１は、特許文献１と同様に、ネット編地２が一部において地面４より浮いた状態にあるので、害獣の脚足を確実に拘束でき、防獣機能が優れているとされている（特許文献２の段落［００２０］参照。）。
しかしながら、前記防獣ネット柵１は、地面４に対して水平な支柱１１の外面にネット編地２が張られてはいが、固定はされておらず、ネット編地２が張られている立設した支柱１１どうしも固定されていないため、水平な支柱１１に獣が強く接触すると、ネットが絡みつくことで防獣ネット柵が破損し、この破損した箇所から別の獣が侵入して獣害が発生する可能性がある。この場合、補修は可能であるものの、防獣ネット柵１が破損していないかを定期的な見回りが必要となるなど、メンテナンスにも注力する必要がある。
In addition, a beast net fence 1 as shown in FIG. 3 of Patent Document 2 is also proposed. As in the case of Patent Document 1, since the net knitted fabric 2 partially floats from the ground 4 in the same manner as in Patent Document 1, the leg protection of the harmful animal can be reliably restrained, and the animal protection function is excellent. (See paragraph [0020] of Patent Document 2).
However, although the net fabric 2 is stretched on the outer surface of the column 11 horizontal to the ground 4, the anti-beast net fence 1 is not fixed but is fixed and the net fabric 2 is stretched. Because the set pillars 11 are not fixed to each other, when the beasts come in contact with the horizontal pillars 11 strongly, the net gets entangled and the anti-beast net fence is damaged, and another beast invades from this broken part and the beast harm Can occur. In this case, although repair is possible, it is necessary to focus on maintenance, for example, it is necessary to regularly monitor whether the beast net fence 1 is damaged.
害獣は１匹でも侵入すると、侵入した地域に深刻な被害を発生させることが知られている。一方で、もともと、田畑、山林、法面、斜面などは、市街地の家屋とは異なり、侵入を防ぐ必要がある面積が極めて大きく、地盤が水平となっていないケースが大半で、コスト等の面から、塀や壁などのように獣の侵入を確実に防止できる手段を採用し難いという問題がある。したがって、田畑、山林、法面、斜面などにおいても、設置が可能で、かつ害獣の侵入をより効率的に防ぐための新たな手段が求められていた。 It is known that even one harmful animal can cause serious damage in the area where it has invaded. On the other hand, the fields, forests, slopes, slopes, etc. are originally different from houses in urban areas, and the area where it is necessary to prevent intrusion is extremely large, and in many cases the ground is not horizontal. Therefore, there is a problem that it is difficult to adopt means that can reliably prevent the invading of the beast, such as a fence or a wall. Therefore, new means have been sought which can be installed in fields, forests, slopes, slopes, etc. and to prevent the infestation of harmful animals more efficiently.
上記のような事情に鑑み、本発明の目的は、田畑、山林、法面、斜面などに設置でき、かつこれらの土地へのシカやイノシシなどの大型の害獣の侵入を長期間防止できる害獣侵入防止用構造体および前記害獣侵入防止用構造体を用いた害獣侵入防止方法を提供することにある。 In view of the circumstances as described above, the object of the present invention is to set up in fields, forests, slopes, slopes, etc., and prevent harmful substances such as deer and wild boars from entering the land for a long time It is an object of the present invention to provide a structure for preventing invading animals and a method for preventing invading animals using the structure for preventing invading pests.

本発明の害獣侵入防止用構造体は、骨組体及び該骨組体に張り付けて固定された金網からなり、前記骨組体が、地盤上に並列状に立設される複数個の支柱枠杆及び該複数個の支柱枠杆間に横架される単又は複数個の横架杆を設けていることで、高さと幅のある構造体となっているため、公知の害獣防止柵と比べると、例えば、シカのように跳躍して侵入を図る害獣や、イノシシのように地面を掘り起して侵入を図る害獣に対しても、侵入を困難にしている。また、前記のような骨組体を採用していることで、法面や斜面のような傾斜地でも、長期間、強度を維持しながら設置することができる。また、前記骨組体の表面に金網を張り付けていることで、例えば、シカやイノシシなどが害獣侵入防止用構造体に接触した場合でも、構造体の形状が維持でき破損しにくくなっている。 The harmful substance intrusion preventing structure of the present invention comprises a skeleton and a wire mesh affixed to and fixed to the skeleton, and the skeleton comprises a plurality of column frameworks erected in parallel on the ground and By providing a single or a plurality of horizontal crossbars that are spanned between the plurality of support pillars, a structure having a height and a width is obtained, compared with a known pest control fence. For example, it is difficult to intrude on a pest that leaps and invades like a deer and a pest that digs up the ground and invades like a boar. Moreover, by adopting the above-mentioned skeleton, even on a slope such as a slope or slope, installation can be performed while maintaining the strength for a long time. Further, by adhering a metal mesh to the surface of the above-mentioned skeleton, for example, even when deer or wild boar etc. contact a pest invasion preventing structure, the shape of the structure can be maintained and it is difficult to be damaged.
前記骨組体は、複数個の前記支柱枠杆の上部どうしを前記横架杆で連結して構成されていることで、金網が張りやすく、支柱枠杆どうしの立設状態を安定に維持しやすい。 The framework is constructed by connecting the upper portions of a plurality of the support frame rods by the cross support rods, so that the wire mesh can be easily tightened and the standing state of the support rod rods can be stably maintained. .
前記骨組体は、複数個の前記支柱枠杆の脚部どうしを前記横架杆で連結して構成されていることで、害獣が接触し易い害獣侵入防止用構造体の側面の強度を高めることができる。 The skeleton is formed by connecting the legs of a plurality of the support frame rods by the lateral bridge rods, so that the strength of the side surface of the harmful animal invasion preventing structure which is easily accessible to harmful animals is obtained. It can be enhanced.
前記支柱枠杆の上部の少なくとも外側となる側を中央に向かって徐々に高くなる傾斜形状にすることで、害獣が害獣侵入防止用構造体を外側から見た場合に、支柱枠杆の脚部による高さに加えて、支柱枠杆の上部の傾斜形状により害獣侵入防止用構造体の高さに奥行きがあることをより強調することができるために、シカのように跳躍力に優れた害獣であっても飛び越える衝動をより強く抑える効果が期待できる。 At least the outer side of the upper part of the pillar frame is gradually inclined toward the center, so that when the harmful animal sees the harmful animal intrusion preventing structure from the outside, In addition to the height by the legs, it is possible to emphasize the presence of depth in the height of the structure for preventing entry of pests by the inclined shape of the upper part of the support frame, so that it is possible to make jumping power like deer. Even with a good pest, the effect of suppressing the jumping impulse more strongly can be expected.
前記支柱枠杆の前後の脚部どうしを連結する補強杆をさらに備えることで、支柱枠杆の立設した状態をより強く保持することができる。 By further providing a reinforcing weir connecting the front and rear legs of the support frame, it is possible to hold the erected state of the support frame stronger.
また、平面状の柵部より構成され、前記金網上に前記横架杆に対して平行に立設される柵体をさらに組み合わせることで、害獣が害獣侵入防止用構造体を跳躍して乗り越えることを防止することができる。 Further, by further combining a fence body which is formed of a flat fence portion and is erected in parallel to the horizontal bridge over the wire mesh, a harmful animal jumps over the harmful animal intrusion preventing structure. It is possible to prevent overcoming.
前記金網上または横架杆に忍び返しを設けることで、害獣が前記害獣侵入防止用構造体を飛び越える衝動をより強く抑える効果をより高めることができる。 By providing the backrest on the wire mesh or the crossbar, it is possible to further enhance the effect of more strongly suppressing the impulse of the harmful animal to jump over the harmful animal intrusion preventing structure.
本発明の害獣侵入防止用構造体は、シカまたはイノシシの大型の害獣に対して特に有効である。 The pest invasion preventing structure of the present invention is particularly effective against large deer or wild boar pests.
以上のように本発明の害獣侵入防止用構造体を、田畑、山林、法面、斜面などの周囲、特に法面や斜面などのように平地に比べて施工に労力を必要とする場所に設置することで、害獣の侵入を効率よく防止することができ、しかも前記害獣侵入防止用構造体は従来のネット柵に比べて強度が高いため、長期間の害獣の侵入を防止でき、また、害獣が接触しても形状が維持でき破損しにくくなっているため、害獣侵入防止用構造体を設置した現場を定期的に見回る労力も顕著に軽減することができる。
また、前記害獣侵入防止用構造体の内部に害獣の侵入を防止できる忌避植物を植生することで、害獣の侵入をより防止することができる。
As described above, the structure for preventing entry of pests of the present invention can be used in areas that require labor for construction around fields, forestry, slopes, slopes, etc., particularly slopes or slopes, as compared to flat land. By installing it, it is possible to efficiently prevent the infestation of harmful animals, and since the structure for preventing invading harmful animals is higher in strength than the conventional net fence, it is possible to prevent the infestation of harmful animals for a long period of time. In addition, since the shape can be maintained and it is difficult to be damaged even when the harmful animal contacts, the labor for periodically looking around the site where the harmful animal intrusion preventing structure is installed can be significantly reduced.
Moreover, invasion of a harmful animal can be prevented more by planting the repellent plant which can prevent the intrusion of a harmful animal in the inside of the structure for preventing harmful animal invasion.
以下、本発明の実施の形態について説明する。 Hereinafter, embodiments of the present invention will be described.
本発明の害獣侵入防止用構造体１は、図１に示すように、骨組体２及び該骨組体２に張り付けて固定された金網３からなる。このように骨組体２と金網３とが固定されていることで、害獣侵入防止用構造体１の強度を向上することができる。また、一般の防止柵では、例えば、前記特許文献１、２のように樹脂製のネットが使用されているが、このネットにシカなどの大型害獣が接触するとネットに害獣の手足が絡まり、その状態で害獣が暴れると防止柵自体が破損してしまう。そして別の害獣が破損部分から侵入する場合がある。これに対して、本発明の害獣侵入防止用構造体１では、金網３が前記骨組体２に張り付けて固定されていることで、シカやイノシシなどの大型の害獣が金網３に接触しても害獣が金網３への絡みつくことがなく、また強度が高くなるため、害獣侵入防止用構造体１の破損を防止することができる。 The harmful substance intrusion preventing structure 1 of the present invention comprises, as shown in FIG. 1, a skeleton 2 and a wire mesh 3 affixed and fixed to the skeleton 2. By fixing the framework 2 and the wire mesh 3 in this manner, the strength of the harmful animal intrusion preventing structure 1 can be improved. Also, in general protection fences, for example, resin nets are used as in Patent Documents 1 and 2, but when a large pest such as deer comes in contact with the net, the limbs of the pest entangle with the net If the harmful animals go wild in that state, the fence will be damaged. And another pest may invade from the damaged part. On the other hand, in the harmful animal intrusion preventing structure 1 of the present invention, the large scale harmful animal such as deer and wild boar contacts the wire mesh 3 by the wire mesh 3 being stuck and fixed to the skeleton 2. However, the harmful animal is not entangled in the wire mesh 3 and the strength is increased, so that the damage to the harmful animal intrusion preventing structure 1 can be prevented.
前記骨組体２は、図２に示すように、地盤Ｇ上に並列状に立設される複数個の支柱枠杆４（４’、４’’）及び該複数個の支柱枠杆４（４’、４’’）間に横架される単又は複数個の横架杆５を備える。このように、支柱枠杆４に横架杆５を組み合わせることで、例えば、立設されている支柱枠杆４の転倒を防止することができる。 As shown in FIG. 2, the framework 2 includes a plurality of support frame rods 4 (4 ′, 4 ′ ′) erected in parallel on the ground G and a plurality of support rod frames 4 (4 ', 4' ') is provided with one or more crossbridges 5 which are laid across. As described above, by combining the horizontal support rods 5 with the support rod members 4, it is possible to prevent, for example, the overturn of the support rod members 4 that are erected.
前記支柱枠杆４は、図２、３に示すように、地盤Ｇ上に立設される脚部４ａおよび前記脚部４ａの上端部に接続される上部４ｂから構成されている。
このように地盤Ｇ上に立設した脚部４ａおよび上部４ｂの高さにより、害獣が害獣侵入防止用構造体１の外側から内側へ飛び越えて侵入することを防止する効果がある。なお、前記脚部４ａおよび上部４ｂとは一体の部材から構成されていてもよいし、別の部材から構成されて組立可能に接続されていてもよい。
As shown in FIGS. 2 and 3, the column frame 4 is composed of a leg 4 a erected on the ground G and an upper portion 4 b connected to the upper end of the leg 4 a.
