The installed beast invasion prevention equipment has a configuration in which a plurality of rods are installed on the upper surface thereof. The bar area 1s where a plurality of bars are installed is walkable and vehicle-friendly. A space portion is arranged under the installed bar material, and the space portion can be visually recognized from the gaps between the plurality of bar members.

Next, an example of the beast invasion prevention equipment according to the present invention will be described in detail.

As shown in FIG. 1, the beast invasion prevention equipment includes a groove member 10 and a plurality of bar members 20 installed on the upper surface side of the groove member 10.
In this embodiment, a groove member having a U-shaped cross section is used as the groove member.
As shown in FIG. 3, the bar member 20 extends in the direction (orthogonal direction in this embodiment) D2 (see FIG. 3) intersecting the groove extending direction D1 of the groove member 10, and the groove member 10 It is installed on the upper surface.

The groove member 10 is a so-called secondary concrete product, and as shown in FIG. 7, includes a bottom portion 10a and a pair of side portions 10b and 10b extending upward from both ends of the bottom portion 10a.
Then, a holding structure (holding member) 15 described later is formed at the upper end portion (upper end portion of the groove member) of this side portion.
Further, the groove member 10 has an upper end portion of a pair of side portions 10b having a tapered shape toward the upper end edge. In this embodiment, the groove outer surface of the side portion 10b extends in a direction orthogonal to the installation surface of the groove member 10 (upward in FIG. 7). On the other hand, the groove inner surface of the side portion 10b has an inclined surface 10c at the upper end portion of the side portion 10b, which is inclined outward from the bottom side of the side portion 10b toward the tip edge. That is, the side portion 10b of the groove member 10 has a tapered shape toward the upper end edge side in the front view (see FIG. 7), and the width of the upper end surface of the groove member 10 in the front view is the width of the side portion 10b. It is narrower than the width (thickness). The thickness of the upper end portion of the side portion 10b in the width direction D2 is preferably 100 mm or less, for example. As will be described later, in this embodiment, a plurality of groove members 10 are arranged in parallel. In this case, when the groove members 10 are adjacent to each other, the thickness of the side portion 10b of the groove member 10 is preferably 200 mm or less. In this embodiment, the upper end of the side portion 10b is tapered, and the width of the upper end portion is narrower than the width of the base portion of the side portion 10.

The beast invasion prevention equipment 1 of this embodiment includes a plurality of groove members 10.
The plurality of groove members 10 are installed in a state of being arranged in parallel. Specifically, the grooves of each groove member 10 are arranged so that the extending directions D1 of the grooves are parallel to each other.
Further, the plurality of groove members 10 are installed in a state of being adjacent to each other (contacting state), and the holding structures 15 of the adjacent groove members 10 are adjacent to each other (contacting).
Further, the plurality of groove members 10 are arranged in a state in which the positions of the recesses 11 described later in the holding structure 15 adjacent to each other are the same. Therefore, when the bar 20 is installed in the recess 11, the bar 20 can be easily installed so as to straddle the plurality of groove members 10.

As shown in FIG. 6, a recess (holding portion) 11 for holding the bar member 20 to be installed is formed on the upper portion of the side portion 10b of the groove member 10. A plurality of recesses 11 are formed.
That is, the upper end portion of each side portion 10 of the groove member 10 is provided with a holding structure (holding member) 15 in which a plurality of recesses 11 for holding the bar member 20 are formed. As will be described later, the holding structure 15 is arranged at the height position of the ground (for example, the height position of the road surface of the road) at the place where the beast entry prevention device 1 is installed, and the longitudinal direction thereof comes and goes. It is arranged in a state of extending in the direction W.

Each recess 11 is, when prevention equipment 1 is installed, is formed in the holding structure 15 of the groove member 10 such that the state which opens upward, when viewed from the side of the groove member 10, the concave shape Is formed so that it can be visually recognized (see FIG. 6).
The plurality of recesses 11 of the holding structure 15 are formed at equal intervals. Therefore, when the rods 20 are installed in each recess 11, the plurality of installed rods 20 are arranged at regular intervals (equal intervals).

Each recess 11 includes a flat bottom surface 12 and a pair of side surfaces 13, 13 extending upward from the bottom surface 12.
Each of the side surfaces 13 and 13 is a surface extending from the bottom surface 12 to the upper end side, and is an inclined surface in this embodiment. That is, the width of the recess 11 (width dimension in the direction D1) is divergent from the bottom surface 12 toward the upper end side.
Each of the side surfaces 13 and 13 extends in a direction corresponding to the width direction D1 of the groove member 10, and extends in a direction corresponding to the extending direction of the bar 20 installed in the recess 11.
Further, the holding structure 15 has a convex portion 14 formed between the plurality of concave portions 11. The convex portion 14 has a tapered shape toward the upper side (upper end edge side of the side portion 10b of the groove 10) in both the side view (see FIG. 6) and the front view (see FIG. 7).

In the present embodiment, the width of the bottom surface 12 of the recess 11 (width dimension in the direction D1) is the same as the width (diameter) of the bar 20. The bar 20 is installed in contact with the bottom surface 12 of the recess 11.
As shown in FIGS. 6 and 3, each bar 20 installed in the plurality of recesses 11 is installed in the recess 11 in a state of extending in the direction D2 orthogonal to the extending direction D1.

Further, as described above, the side surfaces 13 and 13 of the recess 11 are inclined toward the upper side in a divergent manner, and as shown in FIG. 8, the width 12W of the bottom surface 12 and the diameter 20D of the bar 20 are the same. Therefore, the bar 20 is installed in the recess 11 with a gap between the rods 20 and the side surfaces 13 and 13. That is, the width dimension 11 Wm of the recess 11 at the intermediate height position (center height position) Hm where the width of the bar 20 is maximum is longer than the diameter (width dimension) 20D of the bar 20.
In this embodiment, the bar 20 has a circular cross section, and the outer peripheral surface of the bar 20 is a cylindrical surface (curved surface having an arc-shaped cross section). Therefore, the bar 20 in the recess 11 can roll and move on the bottom surface.

As a result of various studies, the diameter 20D of the bar 20 is preferably, for example, 30 mm or more, and preferably 100 mm or less. As a result of various studies, the gap size 20C (see FIG. 8) between adjacent rods is preferably, for example, 30 mm or more, preferably 80 mm or less.

Note that FIG. 6 shows a state in which a part of the bar 20 is removed, but this is a state in which it is removed for convenience in order to clarify the shape of the recess 11, and is actually in the state of being removed. In the beast invasion prevention equipment 1, rods 20 are installed in all the recesses 11.

As shown in FIG. 8, the depth (height dimension) 11h of the recess 11 is shorter than the diameter 20D of the bar 20. Therefore, the bar 20 is installed in a state where the upper end 20p of the bar 20 is located above the upper end surface (upper end) 14a of the groove member 10. In other words, the upper end 20p of the installed bar 20 is located above the upper end 14a of the recess 11.
That is, the prevention equipment 1 of the present embodiment includes a protruding portion 20u protruding above the upper end 14a of the groove member 10.
In this embodiment, the bar 20 is a member having a circular cross section as described above, and the upper side surface (outer peripheral surface) of the protruding portion 20u is composed of the outer peripheral surface of the bar 20. That is, the upper side surface of the protruding portion 20u is a cylindrical surface (curved surface having an arc-shaped cross section) that is convex upward.

The protrusion 20u has an inclined surface in the descending direction (downward) from the position of the upper end edge 20p toward both sides of the traffic direction W. The inclined surface is a curved surface.
The height 20h of the protruding portion 20u (the protruding height dimension of the bar 20 from the upper end surface 14a of the groove member) is the length dimension from the upper end surface 14a of the groove member 10 to the lower end 20b of the bar 20 (inside the recess 11). Is shorter than the height dimension of).
In other words, the upper end position 14a of the recess 11 is higher than the position where the width dimension of the horizontal cross section of the installed bar 20 is maximized (intermediate height position Hm in the vertical direction of the bar 20 in FIG. 8). The position. With such a configuration, more than half of the bar 20 is arranged in the recess 11.

Further, the surface of the outer peripheral surface of the bar 20 (the outer peripheral surface having a cylindrical shape in this embodiment) is a smooth surface.
In the present embodiment, a pipe made of vinyl chloride resin is used as the outer peripheral member constituting the outer peripheral surface of the bar 20. The core member inside the outer peripheral member of the bar 20 has a structure in which reinforcing bars are arranged and filled with mortar (not shown). That is, the bar 20 includes an outer peripheral member having a smooth outer surface and a core member arranged inside the outer peripheral member, and the core member is a structural material containing reinforcing bars. The beast invasion prevention equipment using the bar material having such a structure allows people to walk on it, and also allows vehicles such as light vehicles and passenger cars used for work in the mountains to pass through.

By the way, in the beast invasion prevention equipment 1 of the present embodiment, when the prevention equipment 1 installed outdoors is visually recognized, the appearance, that is, the visible state of the upper surface of the prevention equipment changes depending on the viewing angle (or the viewing position).
Here, as shown in FIG. 9, a long-distance line of sight A at a position away from the prevention equipment 1, a medium-distance line of sight B at a position slightly close to the prevention equipment 1, and a short-distance line of sight C at a position close to the prevention equipment 1 are taken as examples. It will be explained by listing in.
In FIG. 9, the auxiliary lines a, b, and c shown by the alternate long and short dash lines are auxiliary lines shown to clearly separate the angles of the long-distance line of sight, the medium-distance line of sight, and the short-distance line of sight.
Further, here, in particular, the visual state of the central area (sometimes referred to as the bar area 1s) on the upper surface of the prevention equipment 1 in which the plurality of bar members 20 are installed will be mainly described.

First, when the prevention equipment 1 (particularly the center of the prevention equipment 1) is viewed from a long-distance line of sight A, since the depression angle of the line of sight is small, only the bar 20 can be visually recognized.
Then, in the middle-distance line of sight B, in addition to the bar member 20, the upper end portion (upper surface of the holding structure 15) 14a of the groove member 10 can be visually recognized. Since the material, shape, color, etc. of the upper end surface 14a of the bar 20 and the groove member 10 are different, the appearance of the bar area 1s of the prevention equipment 1 from the long-distance line of sight A to the medium-distance line of sight B. Changes.
Further, in the short-distance line-of-sight C, the in-groove space portion 25 of the groove member 10 can be visually recognized through the gap 20C of the adjacent rod member 20. Since the space portion 25 is a space shielded by the bar member 20, the visual state of the space portion 25 is different from that of the bar member 20 and the upper end surface 14a of the groove member 10, and the medium-distance line of sight B to the short-distance line of sight B. At C, the appearance of the bar area 1s of the prevention equipment 1 changes further.

That is, the beast invasion prevention equipment 1 of the present embodiment is configured so that the appearance (recognized pattern or pattern) changes significantly when the angle of the line of sight of the person or the beast who sees the prevention equipment 1 changes ( 9 and 10). In addition, the appearance does not change gradually, but at a certain line-of-sight angle, the appearance changes suddenly (or suddenly).
Therefore, for example, when a person or a beast moves from a position of a long-distance line of sight A, which is relatively far from the prevention equipment, to a position of a medium-distance line of sight B, or when a change from a medium-distance line of sight B to a short-distance line of sight C, this implementation By recognizing the change in the appearance of the prevention equipment 1 of the embodiment, the existence of the prevention equipment 1 of the present embodiment can be easily, quickly and surely noticed.

Next, the installation of this prevention equipment will be described.
The beast invasion prevention equipment 1 of the present embodiment is used, for example, by being installed at a position in the middle of a road such as a mountain road or a forest road located (connecting) between a beast habitat such as a forest and a village (Fig.). 2).

When installing, dig down the road so that the upper surface of the beast invasion prevention equipment after installation is located on the road surface R (see FIG. 1). Then, leveling concrete 30 is struck on the bottom surface that has been dug down. The upper surface of the leveled concrete 30 is a surface on which the groove member 10 is installed, and is preferably a flat surface. When draining water using the groove inside the groove member 10, the upper surface of the leveling concrete 30 can be made an inclined flat surface in consideration of drainage.
After the leveling concrete 30 has hardened, a plurality of groove members 10 are installed on the leveling concrete 30. When installing the groove member 10, the groove member 10 is installed so that the traveling direction of the road (traffic direction W) and the extending direction D1 of the groove member 10 (extending direction of the groove) coincide with each other. Further, as shown in FIG. 4, in the present embodiment, a plurality of groove members 10 (two in the present embodiment) are continuously arranged side by side in the vertical direction.
After installing the plurality of groove members 10, a plurality of rods 20 are installed on the upper surface of the groove members 10. This completes the installation of the beast invasion prevention equipment of this embodiment.
As described above, the beast invasion prevention equipment of this embodiment is excellent in that it is easy to install and the beast invasion prevention measures can be taken promptly.

Each bar 20 is installed in a state of extending in a direction intersecting (here, an orthogonal direction) with respect to the extending direction D1 of the holding structure 15 at the upper end of the groove member 10. As a result, a bar area 1s in which a plurality of bar 20s are arranged is formed on the upper surface of the prevention equipment 1. The bar area 1s is installed at the height of the road surface where it is installed. The bar area 1s is walkable and vehicle-friendly.

In the installed beast invasion prevention equipment 1, the bar member 20 straddles the space portion 25 of the groove member 10 (that is, the space portion in the groove surrounded by the bottom portion 10a of the groove member 10 and the side portions 10b and 10b on both sides). Installed in a state.
This space portion 25 communicates with the space above the equipment through the gaps 20c of the plurality of rods 20, and is a space in which the feet of animals such as deer caught in the beast invasion prevention equipment 1 fall.

If the beast invasion prevention equipment 1 of this embodiment is installed on a road, for example, the invasion of beasts via the road can be prevented. Examples of the beast referred to here include wild deer of the family Cetartiodactyla and wild boars of the family Cetartiodactyla.
The beast invasion prevention equipment 1 of the present embodiment is more suitable for invasion prevention measures for such relatively large vermin than so-called small animals.

Note that FIG. 2 illustrates an image of the installed state, and the groove members 10 are not installed to the full width of the road. It is preferable to install it (see FIG. 10). Further, a structure capable of more reliably preventing the beast from passing through the beast invasion prevention equipment, such as providing members such as walls and fences on both sides of the road width so as to sandwich the installation area of the groove member 10, is more preferable.

Further, the prevention equipment 1 of the present embodiment may be installed not only on a road extending horizontally but also on a road inclined in the traffic direction W. In general, the road often has no slope (less) in the width direction from the viewpoint of ease of walking and vehicle travel.
However, in the installation of the prevention equipment 1 of the present embodiment, even if the road to be installed is inclined in the traffic direction W, if the road width direction is horizontal, the bar 20 is installed horizontally. That is, when installing or replacing the bar 20, the bar 20 can always be handled in a horizontal state. On the other hand, even in a device having the same purpose, in the case of a configuration in which a plate-shaped member is installed on the upper surface of the device, the plate-shaped member is tilted according to the inclination of the road in the traffic direction. Need to be installed.

By the way, if the beast habitat such as forests and the village are completely separated, the invasion of beasts can be prevented, but the road is an infrastructure necessary for the lives of the inhabitants, and it is necessary to secure the passage of the inhabitants. is there. As a method of preventing the invasion of beasts via this road, for example, it is conceivable to install a fence (see Fig. 10) in the middle of the road, open the road only during the daytime, and block the road at night. You can get it, but it takes time and cost. In particular, it is not easy to secure workers in mountainous areas such as marginal villages where depopulation has progressed.
In this respect, the beast invasion prevention equipment of this embodiment allows the passage of residents and vehicles while preventing the invasion of beasts, and does not require the above-mentioned road opening and blocking work to be managed. No hassle.

In addition, beast invasion prevention facilities are usually installed outdoors, but maintenance of prevention equipment is required to maintain the prevention effect.
The contents of maintenance include, for example, cleaning of the beast invasion prevention equipment, repair such as replacement of parts when a part of the beast invasion prevention equipment is damaged (malfunction), and the like.
In this respect, the beast invasion prevention equipment of this embodiment is easy to maintain.

For example, in the prevention equipment 1 of the present embodiment, only one end of the bar 20 is installed in the corresponding recess 11 and the other end is installed in the corresponding other recess 11. The structure is such that the material 20 can be arranged and installed at an accurate position. Therefore, it is possible for one person to install and replace the bar 20 on the upper surface of the prevention equipment 1. Further, when the side surfaces 13 and 13 of the recess 11 are inclined surfaces, the rod 20 material can be easily attached and detached. In these respects, it is also excellent in maintainability.
Further, the bar member 20 is held in the upper surface portion of the groove member 10 by being installed in the recess 11. Therefore, when dead leaves or soil accumulate in the recess 11, the bar 20 can be removed once and easily cleaned and removed, and the bar 20 can be quickly installed after the cleaning is completed. Further, even if some object is caught in the gap between the adjacent bar members 20, by removing one or both of the bar members 20, it is possible to easily take measures such as removing the object.
Further, the outer surface of the bar 20 can be easily cleaned, and even if dust adheres, it can be easily wiped off. In addition, damage to the bar 20 can be easily visually recognized, and replacement is extremely easy. In addition, it is easy to repair in that the repair can be completed by replacement.

Further, as described above, the bar 20 of the prevention equipment can rotate in the state of being installed in the recess 11. The bar 20 is more likely to be damaged and malfunction as the upper surface exposed to the outdoors. On the other hand, of the bar 20, the part that mainly contributes to the prevention of beast entry is the upper outer peripheral surface, and the lower part facing the inside of the groove member is usually the beast and human feet and vehicles. There is no contact with the tires of. Therefore, if a defect is found on the outer peripheral surface of the protruding portion 20u (see FIG. 8) on the upper side of the rod 20 during the maintenance work, the rod 20 is rotated as an emergency measure to cover the outer surface without any defect. Since the portion can be turned upward, the prevention equipment can be operated while maintaining the beast invasion prevention effect until the bar 20 is replaced at a later date.

Further, in the operation of the beast invasion prevention equipment 1, when a beast is caught in the beast invasion prevention equipment, it is necessary to deal with the beast.
When a beast is caught in the beast entry prevention device 1 of this embodiment, the caught beast can be easily captured and protected by pulling it out of the ditch. Further, in the beast invasion prevention equipment 1 of the present embodiment, it is suppressed that the caught beast is injured. If a hung beast is injured, subsequent treatment and handling can be difficult. In addition, an injured beast may die while hanging.
In this respect, if the structure uses the bar 20 as in the prevention equipment 1 of the present embodiment, the injury of the hung beast can be suppressed, and the hung beast can be smoothly captured and protected, and the prevention equipment can be used. It is excellent in terms of ease of operation.

Next, the test results will be described.
The beast invasion prevention equipment 1 of the present embodiment was installed in the middle of the mountain road connecting the forest area and the village area, and a test was conducted to confirm the beast invasion prevention effect.
When the beast invasion prevention equipment installed for a certain period of time was monitored by a surveillance camera for 24 hours and the surveillance video was confirmed, the beast did not enter the remote side. As a result, it was confirmed that the beast invasion prevention effect was achieved.
Beast invasion prevention effect is achieved in relation to the ecology, habits, and characteristics of deer and wild boar, such as the characteristics of deer and wild boar's feet (especially the claws installed on the ground) and walking characteristics such as the movement of deer and wild boar's feet. It is believed that there is.

In addition, as a result of checking the surveillance video, there was a video of people involved in forests passing smoothly on foot and a video of vehicles passing smoothly, and people and vehicles were coming and going smoothly.
If the upper portion of the bar member 20 protrudes from the upper end surface of the groove member 10 (a configuration having a protruding portion 20u), a person or a vehicle may pass through any position of the beast entry prevention equipment 1. However, the unevenness of the bar area 1s can be detected through the foot or the tire in contact with the surface of the prevention equipment 1.
Further, when the mountain road on which the prevention equipment 1 of the present embodiment is installed is a road having an inclination in the traffic direction W (uphill, downhill), the prevention equipment 1 installed on such an inclined road may have a slope. Each bar 20 is installed so as to extend in a direction orthogonal to the traffic direction W, and a plurality of bar 20 having a round cross section are arranged at intervals. That is, these plurality of bar members 20 are arranged in a so-called stepped shape.

Although the movable distance is small, the rod 20 can be referred to as a rotating rod or a rolling rod in this respect.
In addition, in other words, this configuration has a thickness in which the bar 20 having a circular bar shape with a circular cross section is in a non-contact state with the bottom surface 12 and one side surface 13 when it is brought into contact with the other side surface 13. It can be said that it is (diameter).
The bar 20 may be installed in a state where it cannot be moved in the recess 11, but the structure in which the bar 20 in the recess 11 can be moved is good for attaching and detaching the bar 20 installed in the recess 11. It can be said that it has excellent maintainability in that respect. Further, it can be said that a sound is generated when the bar 20 comes into contact with the inner surface of the recess.

The bar 20 may have various shapes, but it is preferable that the bar 20 has a smoothly curved rollable shape such as an elliptical cross section, and a bar (round bar) having a circular cross section as in this embodiment is more suitable. preferable.
As the member constituting the outer peripheral portion of the bar member 20, a member having a smooth surface is preferable. For example, a metal pipe such as stainless, which has excellent rust resistance, can be mentioned. Considering long-term use such as maintainability, for example, a pipe made of "vinyl chloride resin" or a pipe made of "polyvinyl chloride resin" can be mentioned. Among them, "hard""vinyl chloride resin" pipes and "polyvinyl chloride resin" PVC products that do not contain plasticizers can be mentioned.
Further, the rod member 20 may be a member having a uniform shape as a whole, but may have a core member inside the pipe constituting the outer peripheral portion as in the rod member of the present embodiment.
Further, each bar member 20 may be an integral single member, but may be formed by arranging a plurality of bar-shaped members in the longitudinal direction from the viewpoint of handleability. When a plurality of rod-shaped members are arranged in the longitudinal direction in this way, the connection position between the adjacent rod-shaped members is the recess of the groove member 10 in the state where the rod members are installed, from the viewpoint of strength and the like. It is preferable that the configuration matches the position.

In the above-described embodiment, the holding member (holding structure 15) arranged to face each other across the space portion is formed in an integral structure with the groove member 10 which is an integral member, but may be a separate member. However, if the opposing holding members (holding structures) 15 are integrated, it is easy to accurately arrange the positions of the opposing recesses 11 that support the same rod 20 at the opposite positions, and the rod 20 is installed. Excellent workability. Further, if the groove member 10 has both holding structures integrally formed, the installation workability of the groove member is excellent.

The side surfaces 13 and 13 of the recess 11 may be orthogonal to the bottom surface 12, but they have maintainability such as attachment / detachment of the bar 20 and can rotate and roll the bar in the recess. The angle formed by the bottom surface 12 and the side surface 13 is preferably an obtuse angle rather than a right angle.
When the side surface 13 of the recess 11 is inclined with respect to the bottom surface 12, the inclination angle of the side surface 13 (the angle formed by the bottom surface 12 and the side surface 13) α1 (see FIG. 8) is to prevent the bar 20 from falling off. From the viewpoint of attachment / detachment workability and conditions of the installation location of the prevention equipment, for example, an angle satisfying the following conditions can be considered. Here, the description will be made on the premise that the bar 20 is installed at the center position of the bottom surface 12 (see FIG. 8). That is, the extension line of the bottom surface 12 which is tangent to the outer peripheral surface of the bar at the surface position 20e of the outer peripheral surface of the bar 20 which is the same height as the height position of the upper end surface 14a of the holding member (holding structure) 15. It is preferable that the above-mentioned angle α1 is smaller than the obtuse angle α2. Specifically, when the side surface 13 is tilted, the angle α1 is preferably, for example, 105 degrees or less, and preferably an angle larger than 90 degrees.
