Description

  TECHNICAL FIELD The present invention relates to a herbivore invasion deterrence technology that prevents medium and large herbivores that eat undergrowth from invading railways and roads.

  In recent years, among wild animals, in Japan, sika deer belonging to the deer family have rapidly increased their population, and a site having railways, roads, etc. provided so as to cross this habitat area (hereinafter referred to as "protected area"). ) Is a problem that deer frequently invade and collide with vehicles frequently.

  It is generally considered that deer have the ability to jump about 2 m, and in order to cope with this, conventional animal intrusion prevention fences with a fence height of about 2 m or more are used, deer jumping and protected areas By setting the height at which it can not invade the side, herbivores such as deer are prevented from invading the protected area.

  Further, in Patent Document 1, it is an animal intrusion prevention fence installed for an animal having excellent jumping power, and an outer fence is provided on the outside of the main fence, and a crossing place for jumping over the main fence is an outer fence It is disclosed that the animal is prevented from jumping over the fence by providing it further outside.

  However, when it invaded a protected area for reasons other than jumping, the height of the fence was high and escape of deer etc. was difficult.

  For example, it is difficult to form a completely closed environment in a protected environment such as a railway or a road, which is a straight environment, and a crossing section such as a crossing for passing a person or a thing inevitably occurs.

  Then, when deer and others intrude from such a crossing section and move to a position away from the crossing section, in a situation where the vehicle moves at high speed, the time margin for moving to the crossing section to escape is avoided to avoid this. There may be no. In addition, since the height of the fence is set high as described above, it is impossible to jump over the fence.

  As a result, deer and the like can not escape from the semi-closed environment covered with the intrusion prevention fence, and there is a problem that a collision with the vehicle occurs.

  Patent Document 2 discloses a facility for animal escape installed on an intrusion prevention fence such as a deer fence as a technology for coping with such a problem. This animal escape facility is to guide the deer deer and the like to escape reliably from the inside of the road site to the outside of the road site, and is the escape bank and the fence which guides the deer etc to the escape bank. And a fence provided with an upper tension wire.

  However, when the animal escape facility described in Patent Document 2 is used for a railway or a road, deer and the like can not escape at places other than the escape bank. In the case of a semi-closed environment in which a railway or a road is covered with a fence as described in Patent Document 2, deer and the like panic as the vehicle approaches, but even if they try to escape from the nearest fence, they jump It is not possible to jump over and a collision with the vehicle occurs.

  In addition, when deer and others escape from the semi-closed environment, they are in a state of panic with the approach of the vehicle, and will make quick and energetic leaps, but as a result of such leaps, part of the invasion prevention fence May cause damage to the intrusion prevention fence.

  When components such as wire netting, resin nets, and wires are damaged and greatly bent or dropped off due to such damage, if these enter into roads or tracks, a collision between the components and the vehicle may occur. there were.

  Therefore, in the railways and roads, medium and large herbivores that eat undergrowth, especially taking into consideration the behavior habits of animals belonging to the Sicidae and the Bovine family, while having an intrusion deterrence function, escape easily if temporarily invaded There is a need for a fence that can prevent damage from entering the protected area even if the fence is damaged at the time of escape.

  The net 13 is formed by braiding a resinous cord-like body including a stainless steel wire, and is attached to the lowermost portion of the wire 12c using a predetermined fixing means at a plurality of locations on the upper end thereof It is done.

  The length in the width direction (± Y direction in FIG. 1) of the net 13 is such that it is bridged between at least three columns 11. Further, the length of the net 13 in the longitudinal direction, ie, the part hanging down from the ± Z direction to the ± X direction in FIG. 1 is the extent to which the net 13 extends along the slope G from the wire 12c when attached to the wire 12c. The length of the

  The end of the portion extending along the slope G of the net 13 is fixed to the slope G by the peg 3 at a predetermined interval.

  Next, the installation method of the herbivore invasion deterrent fence 1 mentioned above is demonstrated.

  First, a plurality of foundation piles 112 are placed on the slope G, which is an installation place of the herbivore entry deterrence fence 1, at predetermined intervals.

  Next, the pillar main body 111 is placed vertically on the ground so that a bolt protruding from the top of the foundation pile 112 driven on the slope G is inserted into the hole 111 d formed in the bottom of the pillar main body 111. Be placed. At this time, the notch portion 111a of the column main body 111 is placed so as to face the lower side of the slope G, that is, the opposite side to the protected area side.

  Next, in this state, the foundation pile 112 and the column main body 111 are bolted. This bolt fastening is performed by fitting the washer W2 and the nut N2 from the side of the column body 111 to the bolt of the foundation pile 112 projecting from the hole 111d of the bottom of the column body 111.

  Next, as shown in FIG. 12, the wires 12 a, 12 b, and 12 c are inserted from the lower side of the slope G to the round holes 111 b from the notches 111 a of the column main bodies 111 of the plurality of columns 11. FIG. 12 is a partially enlarged perspective view showing a state in which the wire is stretched around the column main body 111. As shown in FIG.

  In the present embodiment, the wires 12a, 12b, and 12c are inserted through the three round holes 111b in the third, fourth, and fifth stages from the top of the column main body 111. Thus, the wires 12a, 12b and 12c are stretched between the plurality of continuous column bodies 111 (see FIG. 2). The distances between the wires 12a and 12b and between the wires 12b and 12c at this time are both H2.

  Next, the column cover 113 is attached to the column body 111. FIG. 13 is a partially enlarged perspective view showing a state in which the column cover 113 is in contact with the column main body 111 on which the wire is hung.

  The support of the support cover 113 is performed by bringing the support cover 113 into contact with the support main body 111 from below the inclined surface G so as to sandwich the wires 12a, 12b and 12c wound around the support main body 111 with the support main body 111.

  The abutment of the column cover 113 with the column body 111 is performed such that the wires 12a, 12b, and 12c are inserted into the cutouts 113a of the column cover 113. Thus, the wires 12a, 12b, and 12c are gripped by the round hole 111b of the column main body 111 and the notch 113a of the column cover 113.

  Further, in this state, the hole 111c of the column main body 111 and the hole 113c of the column cover 113 face each other, and the holes 111c and 113c communicate with each other.

  Next, as shown in FIG. 14, the column body 111 and the column cover 113 are bolted and fixed in this state. FIG. 14 is a partially enlarged perspective view showing a state in which fixation with a bolt B1 and a nut N1 is further performed from the state of FIG.

  The bolt B1 is inserted through the washer W1 into the hole portion 111c of the column body 111 and the hole portion 113c of the column cover 113 in communication with each other, and the nut N1 is screwed into the inserted bolt B1. And the pillar cover 113 are fixed.

  Thus, the column main body 111 and the column cover 113 are fixed, and the column 11 is completed, and a state in which the wires 12a, 12b, 12c are stretched around the column 11 is formed. The end portions of the wires 12a, 12b, 12c are fixed to the supports 11 or the ground G at both ends using predetermined means, and the slack or falling of the wires 12a, 12b, 12c is effectively prevented.

  Next, the net 13 is attached to the wire 12c at the lowermost portion of the wires 12a, 12b, 12c stretched between the columns 11. The attachment of the net 13 is performed by fixing the upper end portion of the net 13 to the wire 12 c using an arbitrary means such as a cord, a clip, or a binding band. A wire 12d is provided near the ground of the column 11, and the middle part of the net 13 and the wire 12d are fixed using an arbitrary means such as a cord, a clip, a binding band, etc. like the wires 12a, 12b, 12c. .

  Thus, in the state in which the net 13 is attached to the wire 12 c, the lower part of the net 13 is in the state of hanging on the slope G. By fixing the lower portion of the net 13 to the slope G using the pegs 3, the herbivorous animal invasion deterring fence 1 according to the present embodiment is completed.

  Here, the round hole portion 111b is a structure in which the wires 12a, 12b, and 12c can be temporarily placed without falling off in a state where the column main body 111 is inclined and installed on the inclined surface G.

  Therefore, when installing the herbivore invasion deterrence fence 1 over a long extension on the slope G, the support of the support cover 113 is not performed each time the support support 11 is installed, and a large number of support main bodies 111 are preceded. The wire 12a, 12b, 12c can be temporarily placed in the round hole portion 111b by installing on the slope G.

  Thereby, a large number of support | pillar covers 113 can be attached continuously after that, and the workability in a slope is favorable.

  The round hole portion 111b may extend as long as the wires 12a, 12b, 12c, and 12d can be temporarily placed without falling off in a state where the column main body 111 is erected on the inclined surface G and extends from the notch portion 111a It may be a notch.

  Next, the effects exerted by the herbivore invasion deterring fence 1 having the above-described configuration will be described.

  First, the invasion deterring effect of the herbivore 2 will be described. FIG. 15 is a view showing the length of each part of the herbivore which is a target of the herbivore invasion deterrent fence according to the present invention. FIG. 16 is a diagram showing the length of each part of the head of the herbivore of FIG. FIG. 17 is a view for explaining the penetration deterring effect of herbivores to the protected area by the herbivore deterring fence according to the embodiment and the ease of escape from the protected area.

  As shown in FIGS. 15 and 16, the herbivore 2 has a shoulder height of 2a, a head height of 2b, a head length of 2c, and a head width of 2d.

  And, as shown in FIG. 2, FIG. 3 and FIG. 17, while the height from the slope G to the wire 12a at the top is H1, the herbivore entry deterrence fence 1 has two steps with the wire 12a. The distance between the eye wire 12b and the distance between the second stage wire 12b and the third stage wire 12c is H2.

  Due to the nature of medium- and large-sized herbivore animals 2 that eat deer and other undergarments, they try to bypass or straddle the fence if there is an obstacle such as a fence in the traveling direction. Even if it is a fence height that can jump by jumping, jumping hardly occurs unless there are factors that cause jumping such as feeding on the tip of the fence or being driven off later.

  Then, when there is no trigger for jumping, and it is not possible to straddle or dive over the fence, the herbivore 2 moves back or moves along the fence.

  Therefore, in the herbivore entry deterrence fence 1 according to the present embodiment, the wire 12a is provided such that the height from the ground is H1 higher than the shoulder height 2a of the herbivore 2. Therefore, the herbivore 2 can not straddle the wire 12a.

  Thus, according to the herbivore infestation deterrence fence 1 which concerns on this embodiment, it can be effectively deterred that the herbivore 2 straddles this and it invades a protected area.

  Moreover, this intrusion deterrence effect can be further enhanced by erecting the herbivore invasion deterrence fence 1 on the slope G.

  As shown in FIG. 17, when the herbivore 2 located under the slope G, that is, outside the protected area as viewed from the herbivore invasion deterrence fence 1 jumps over the wire 12 a of the herbivore invasion deterrent fence 1, the slope slope You have to jump the height H3 which also added.

  This H3 is usually set to be higher than the height at which the herbivore 2 can jump, that is, higher than the height from the slope G to the wire 12a. Therefore, it is possible to effectively prevent the herbivore 2 from jumping from the lower side of the slope G into the protection area by jumping over the herbivore invasion deterrence fence 1.

  Thus, in the herbivore invading deterrence fence 1 according to the present embodiment, the height of the herbivore invading deterrence fence 1 can be kept lower than that of the conventional fence, and the cost of production and installation and labor at the time of operation It can be reduced.

  Furthermore, in the herbivore invading deterrence fence 1 according to the present embodiment, the net 13 hangs and spreads a sufficient length with respect to the slope G as a measure against the sinking of the herbivore 2, and the end on the slope G side is the slope G It is fixed using peg 3.

  When the herbivore 2 dives into an obstacle, etc., first lowers the neck and dives the nose tip under the obstacle, lifts the neck in that state to lift the obstacle and dive under the obstacle Form a possible space for Then, the herbivore 2 lowers its posture as it is, and dives into the obstacle by penetrating into the space from the tip of the nose to the head and then the neck.

  However, in the herbivore invading deterrence fence 1 according to the present embodiment, even if the herbivore 2 sinks into the net 13 hanging down on the ground and the nose is lifted and the neck is lifted and the end of the net 13 is flipped up, the protected area is visually recognized. It is configured to hang down on the slope G long enough to be unable to

  Specifically, the net 13 has a length which is raised when the herbivore 2 sinks its nose, that is, the sum of the height 2 b of the head of the herbivore 2 and the length 2 c of the head It is configured to hang on the slope G long enough.

  Therefore, even if the herbivore 2 sinks the nose tip under the net 13, it can not visually recognize the tip and can not give motivation for the dive, so it tries to further dive the head and neck. I do not.

  Furthermore, in order to prevent insertion of the nose tip itself by the herbivore 2, the end on the slope G side of the net 13 is fixed to the slope G using the peg 3 as described above. Since the end of the net 13 is fixed by the peg 3, the herbivore 2 can not get its nose tip under the net 13. In addition, since the middle part of the net 13 close to the ground is fixed to the wire 12 d, it is possible to more effectively prevent the herbivore 2 from entering.

  Thus, in the herbivore entry deterrence fence 1 in the present embodiment, it is possible to effectively prevent the herbivore 2 from entering and to prevent entry into the protected area.

  Next, the effect of promoting the escape of the herbivore 2 from the protected area will be described.

  As mentioned above, even if it is a fence of the height which can jump by leaping, herbivorous animals 2 such as deer induce a jump such as feeding on the tip of the fence or being driven off later. If there are no factors, jumping hardly occurs.

  Then, herbivorous animals such as deer that have invaded the protected area side from the cut of the herbivorous animal invasion deterring fence 1 by crossing sections etc. provided on railways, roads etc. are surprised by the approach of vehicles etc. and jumped Try to get over

  At this time, the jumpable height of the herbivore 2 is up to about 3 times the shoulder height, but the height easily exceeded is about 2 times the shoulder height. Therefore, in the herbivore entry deterrence fence 1 according to the present embodiment, the height H1 from the ground to the wire 12a at the top is set to be equal to or less than twice the shoulder height of the herbivore 2.

  Thereby, the herbivore 2 can easily jump over the herbivore animal invasion deterring fence 1 when the vehicle approaches, etc., and can escape from the protected area.

  Further, as shown in FIG. 17, the herbivore 2 in the state of having invaded the protected area above the slope G as viewed from the herbivore invasion deterrent fence 1 jumps over the wire 12 a of the herbivore invasion deterrent fence 1, The height to jump is H4.

  The height H4 is even lower than the height H1 at which the herbivore 2 can jump easily. Therefore, it is even easier for the herbivore 2 to jump over the herbivore invasion deterrence fence 1 and escape from the protected area.

  In addition, when the herbivore 2 jumps over the herbivore entry deterrence fence 1, it is important that the herbivore entry deterrence fence 1 has visibility so as to be able to look over the other side. It is known that the herbivore 2 has good visibility in the jumping direction and is easy to jump when the landing point can be visually recognized.

  If it is a human being and an animal with a certain degree of intelligence, jumping over an obstacle without seeing the other side will control the jumping as fear is accompanied.

  Therefore, in the herbivore invading deterrence fence 1 according to the present embodiment, a space with high visibility is provided in the upper part of the herbivore invading deterrence fence 1 by only having the wires 12a, 12b, 12c passed over the upper part. It secures, and the situation where herbivore 2 is easy to jump is realized.

  Note that this visibility depends on the size of the head of the herbivore 2. Specifically, the head of the herbivore 2 has a vertical length of 2b and a horizontal width of 2d in a front view shown in FIG. 16, and the herbivore 2 is based on the vertical and horizontal sizes of the head, If there is a space larger than this vertical and horizontal size, it will recognize the other side of the fence and will be aware of jumping to the other side of the fence.

  Therefore, the sum of the distance H2 between the wires 12a and 12b and the distance between the wires 12b and 12c, that is, the distance H2 is secured so as to be longer than the vertical length 2b of the head of the herbivore 2. Further, the distance between the columns 11 is also sufficiently wider than the width 2 d of the head of the herbivore 2.

  Thus, in the upper part of the herbivore entry deterrence fence 1, a space wider than the size of the head of the herbivore 2 can be secured, and the herbivore 2 can easily recognize the other side of the fence. It is possible to facilitate jumping of the herbivore invasion deterrence fence 1 when leaving the protected area.

  Specifically, when the herbivore 2 is a horned deer, both the vertical length 2b and the width 2d of the head are about 20 cm, so H2 of the herbivore invasion deterrence fence 1 is 20 cm or more, between the columns 11 If the distance of 20 cm or more, that is, if a 20 cm square space can be secured at the top of the herbivore entry deterrence fence 1, the herbivore 2 can easily jump.

  Furthermore, in the herbivore invasion deterrence fence 1 according to the present embodiment, the herbivore 2 jumped at the time of escape from the herbivore 2 collided with the herbivore invasion deterrent fence 1 and was damaged on the protected area side even when it was damaged. There is also an effect of effectively preventing entry of components.

  When the herbivore 2 jumps from the protected area side and collides with the herbivore invasion deterrence fence 1 and the herbivore invasion deterrence fence 1 bends, the direction of this bending is toward the outside of the protected area, and therefore the herbivorous The animal intrusion deterrence fence 1 is not broken and does not disturb the passage of vehicles and the like.

In addition, the herbivore invasion deterrence fence 1 may be broken due to the collision of the herbivore 2, and the component may come off. However, in the herbivore invasion deterrence fence 1 according to the present embodiment, since the falling-off direction of each component is limited to the outside (+ X direction) of the protected area, the parts dropped off to the protected area (-X direction) invade , Will not interfere with the passage of vehicles, etc.

  Specifically, since the support main body 111 of the herbivore invasion deterrence fence 1 is fixed to the slope G by the foundation pile 112, the jumping direction of the herbivore 2 collides with the outside of the protected area. That is, it curves toward the outside of the protected area and does not curve toward the protected area.

  In addition, since the column cover 113 is bolted to the column body 111, it bends with the column body 111 to the outside of the protected area, or even if the bolted part is broken and falls off, the jumping direction of the herbivore 2 It only falls off towards

  Further, as described above, the wires 12 a, 12 b, 12 c and the net 13, which are the entry inhibiting members of the herbivore 2, are straddled across the three or more columns 11.

  Thereby, since the wires 12a, 12b, 12c and the net 13 are attached to the support 11 from the outside of the protected area, three or more of these members are dropped even if the herbivore 2 jumps. The bridge 11 is straddled over the pillar 11, and the pillar 11 does not get in the way to the protected area side as an obstacle.

  In addition, since the wires 12a, 12b and 12c which are bridged between the columns 11 are bridged across three or more columns 11, even when they are bent or cut by the collision of the herbivore 2, Since the columns 11 become an obstacle, they do not bend or bend toward the protected area.

  Further, even when a part of the net 13 is broken, since the bridge 11 spans over three or more columns 11, the columns 11 become an obstacle, and the torn part does not curve toward the protected area.

  According to the herbivore animal invasion deterring fence 1 according to the embodiment described above, while having a function of deterring the herbivore 2 to invade the protected area, even if the herbivore 2 invades the protected area, emergency escape is easy And, even if the herbivore entry deterring fence 1 is damaged at the time of escape, it is possible to effectively prevent the entry of a damaged material to the protected area side.

  In the embodiment described above, the three wires 12a, 12b and 12c are bridged between the columns 11. However, the present invention is not limited thereto. It can adjust suitably according to the installation situation of the animal intrusion deterrence fence 1.

  Moreover, although the penetration suppression effect was exhibited by bridging the wire between the columns 11, the present invention is not limited to this, and it may be a material that can ensure the penetration suppression effect of the herbivore 2 and the visibility at the time of jumping. A plate member, a net, etc. can be used suitably. In addition to steel materials, resins, wood, natural fibers and the like can also be suitably used as these materials.

  In addition, the net 13 for preventing the herbivore 2 from invading can also be suitably used as long as it can exhibit the invading prevention effect, and a sheet, a plate or the like can also be used. In addition to steel materials, resins, wood, natural fibers and the like can also be suitably used as these materials.

  Further, the end of the net 13 may not reach the slope G and may not be in contact with the slope G, and when not fixed to the slope G, a member having bending rigidity such as steel is provided at the lower end of the net 13 to support Alternatively, the neck 13 may be configured such that it can not lift up and turn up the neck even if the nose tip is sunk by fixing a gap between them or by using a member having bending rigidity in place of the net 13 between pillars.

  Also, the fixing of the net 13 to the slope G may be performed by fixing means other than the peg 3 or by embedding the end portion on the slope G or the like.
