Description

  The present invention relates to an intrusion prevention facility that eliminates wild animals such as deer and sharks that are about to enter a railway track and prevents the wild animals from colliding with a railway vehicle.

  In recent years, the number and distribution of wild deer has increased, and as a result, collisions between railway vehicles and deers have increased. If a railway vehicle collides with a deer, it will interfere with the regular operation of the train, and measures to prevent this will be required. Particularly in Hokkaido, there are frequent collisions between trains and deers, and countermeasures are particularly necessary.

  As a countermeasure, the article for preventing deer intrusion into the railway site shown in Patent Document 1 is to lay a string or granular material soaked with lion feces or an equivalent odorous substance on the railway fence. , Preventing animals from entering the route.

However, since the deer intrusion prevention article shown in the cited document 1 is arranged on a fence along the railroad track, a large amount of money is required to install the fence.
For this reason, the animal intrusion prevention footboard shown in patent document 2 is provided as a technique which excludes the animal which is going to invade into a railroad track, without installing a fence.

  The animal intrusion prevention tread shown in Patent Document 2 is a structure in which a plurality of gaps having dimensions close to the size of an animal's foot such as a heel or an antelope are formed, and the foot fits into the gap. I try to keep animals away by using my dislike habits.

However, although the animal intrusion prevention tread described in Patent Document 2 is installed on the side of the railway track, in large wild animals such as deer, the animal intrusion prevention tread jumps over the animal intrusion prevention tread that may cause the foot to get caught. , May enter the railway track.
When the wild animal is a deer, considering its jumping power, the animal intrusion prevention footboard described in Patent Document 2 needs to be installed in a wide area of 2 m or more on both sides of the track, and there is a problem that the installation cost becomes large. is there.

  The present invention has been made in view of the above-described circumstances, and prevents wild animals from entering the railroad track by jumping over a footboard that may cause a foot to be caught, and reliably securing the wildlife to the footboard. Provide animal invasion prevention equipment that can guide.

In order to solve the above problems, the present invention proposes the following means.
The present invention is a tread board having a large number of gaps that are installed on the side of a railroad track to sandwich an animal's feet, an obstruction fence that is installed above the tread board and prevents the animal from jumping over the tread board, It is characterized by comprising.

According to the present invention, an obstruction fence that prevents the animal from jumping over the tread board is provided above the tread board having a large number of gaps between which the animal's feet are sandwiched. Thus, for example, wild animals such as deer can abandon jumping over the footboard and have their heads lowered to pass through the obstruction fence.
In the state where the head is lowered, the wild animal cannot jump, and therefore, it is not possible to jump over the tread board where the foot may be caught, and it is guided onto the tread board. After that, when a wild animal steps on a stepping board that may get caught in its feet, it moves away from the railroad track because it dislikes this and acts to avoid the stepping board. It is possible to prevent a collision with a wild animal.

In addition, since the animal intrusion prevention equipment according to the present invention has a simple configuration in which an obstruction fence is simply provided above a tread having a large number of gaps between which the animal's feet are sandwiched, for example, one or more obstruction fences are provided. If it is composed of a rope of books, wild animals can be managed with a low budget without incurring a large expense for the installation of the fence.
Moreover, since the jumping of wild animals is prevented by the presence of the obstruction fence, it is not necessary to widen the width of the tread board, and this can also take measures to prevent the invasion of wild animals with a low budget.
In addition, when a prefabricated grating in which partition members forming gaps are assembled in a grid pattern is used as the step board of the present invention, the step board can be easily laid on the side of the railway track.

In addition, in the tread of the present invention, if the head of the partition member that forms the gap is formed in an inclined shape or a mountain shape, the wild animal foot that has stepped on the partition member is slid, and the gap between the partition members As a result, it is possible to efficiently pinch the foot of the wild animal in the gap.
In addition, by installing the railroad track according to the present invention on the upper part of the embankment and laying a resin sheet with a small coefficient of friction on the slope of the embankment, if a wild animal invades beyond the tread board and the obstruction fence, Wild animal feet can be slid by the resin sheet. As a result, wild animals can be reliably prevented from entering the railway track.

It is sectional drawing of the railroad track provided with the invasion prevention equipment of the animal which concerns on this invention. It is a top view of FIG. (A) is an example in which the head of the partition member is formed in an inclined shape, and (B) is an example in which the head of the partition member is formed in a mountain shape.

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a cross-sectional view of a railway track R provided with an animal intrusion prevention facility 1 according to the present invention, and FIG. 2 is a plan view of FIG.

  The railroad track R shown in these figures is a single-track track installed on the embankment 2, and the animal intrusion prevention equipment 1 is installed on the ground G on both sides located under the slope 3 of the embankment 2. Has been.

The animal intrusion prevention equipment 1 includes a footboard 10 installed on the ground G on the side of the railroad track R, and an obstruction fence that is installed above the footboard 10 and prevents the animal from jumping over the footboard 10. 20.

The gap portion 13 formed between the partition members 12 in the tread board 10 is formed to have a size enough to hold a foot of a wild animal deer (indicated by reference sign D), for example, a width of about 10 cm. The width dimension is appropriately changed according to the animal to be prevented from entering.
Moreover, the partition member 12 is formed in the width | variety of about 1 cm, and the foot board 10 whole is formed in the width | variety of about 1 m.
The wild animal D retreats from the railroad track R because he does not want his / her foot to be caught in the gap 13 formed between the partition members 12 of the tread board 10.
In addition, the partition member 12 of the tread board 10 is not limited to being formed by wire rods in a positional relationship parallel to each other, and may be configured by gratings in which the wire rods are arranged in a lattice shape.

1 and 2, the head 12A of the partition member 12 is formed flat, but the head 12A may be formed in an inclined shape as shown in FIG. The head 12A may be formed in a mountain shape as shown in FIG.
If the head 12A of the partition member 12 that forms the gap portion 13 is formed in an inclined shape or a mountain shape in the tread board 10, the foot of the wild animal D that has stepped on the partition member 12 is slid, and the partition member As a result, the foot of the wild animal D can be efficiently sandwiched in the gap 13, and the effect of retracting the animal by the tread board 10 can be further enhanced.

Next, the obstruction fence 20 installed above the tread board 10 will be described.
The obstruction fence 20 is composed of a rope 21 disposed above the step board 10 and along the railroad track R. For example, a large wild animal D such as a deer It is installed at a height where it cannot jump over the obstruction fence 20 and proceed.

That is, wild animals D such as deer abandon jumping over the tread board 10 due to the presence of the obstruction fence 20, and lower their heads to try to pass through the obstruction fence 20 (see FIG. 1).
In the state where the head is lowered, the wild animal D cannot jump, and therefore, the wild animal D cannot be jumped over the tread board 10 that may cause a foot to be caught and is guided onto the tread board 10. After that, when the wild animal D steps on the step board 10 that may get caught in the foot, the wild animal D moves away from the railroad track R because he dislikes this and acts to avoid the step board 10, and as a result As a result, it is possible to prevent the train from colliding with the wild animal D.

  In FIG. 1 and FIG. 2, the rope 21 serving as the disturbing fence 20 is configured by one, but is not limited thereto, and may be configured by a plurality of ropes 21 spaced vertically. The material of the rope 21 is not particularly limited, but is preferably made of steel if durability is taken into consideration. Moreover, it is not limited to comprising the obstruction fence 20 with the rope 21, You may comprise with a metal fence and a wooden fence, The form is not limited.
