BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter protection cover for small animals, which prevents small animals from falling into the gutter and is protected from traffic damage caused by crossing a road.

[0002]

2. Description of the Related Art The present inventor has provided a small animal protection gutter in which an escape path is formed so that a small animal that has previously fallen into the gutter can escape from the gutter (Act No. 5-23667). It is widely used in This small groove for protecting small animals was intended to protect small animals by letting them escape to the side opposite to the road surface, which has fallen into the groove without a lid. However, in recent years, gutters with lids have been widely used also in gutters such as in mountain areas. In the case of a gutter with a lid, it is possible to prevent accidents that small animals fall into the gutter, but on the contrary, it becomes possible to freely enter the road surface, and there are many traffic brutal cases where it is run over by vehicles etc. passing the road. There is.

In particular, some small animals, due to their habits, require movement between land habitat and the sea for spawning, such as the crab, and these small animals form the sea and mountains. An accident occurred in which a car was run over while crossing the road between the two. In order to solve this problem, the present inventors previously formed a small animal entrance / exit path on the side wall of the road shoulder and a tunnel communication opening on the side wall of the road in the gutters provided on both sides of the road, Tunnel communication ports located on both sides of the road are connected by a tunnel, and in the case of a gutter with a lid, the side wall on the road shoulder side is formed higher than the road shoulder surface,
We proposed a small animal protection gutter that prevents small animals from appearing on the road surface and guides them to the tunnel communication port so that they can freely travel on both sides of the road through the tunnel (Japanese Patent Laid-Open No. 2000-734).
4 publication). However, in that case, it is necessary to improve the gutter, and if one of the large gutters has one side wall higher than one, handling such as molding, transportation, and laying becomes difficult,
There was a problem of high cost.

SUMMARY OF THE INVENTION In view of the above situation, the present invention was devised in order to prevent small animals from coming out of a road through a gutter with a lid and getting into traffic trouble. Even if it is provided, it can reliably prevent small animals from entering the road surface, does not make any changes to the U-shaped gutter, is easy to handle and can be manufactured at low cost, and has a special installation space. An object of the present invention is to provide a small animal protective lid for a gutter that can be applied to a conventional U-shaped gutter without requiring any installation work.

[0005]

As a result of further research to solve the above-mentioned problems, the present inventor has found that it can be obtained more effectively and cheaply as compared with the case of changing the shape of the gutter main body. Heading The present invention has been reached.
That is, the small animal protection lid for a gutter of the present invention that solves the above problems is a stand-up that prevents a small animal from entering the lid body surface along the roadside side edge of a flat lid body that covers the gutter opening. It is characterized by having a wall. The rising wall is
It is desirable to have an inclined portion on the road shoulder side, because it is more difficult for small animals to get over it and the pressure from the road surface is eliminated. Further, by opening the cleaning hole in the lid body, it is possible to clean the inside of the gutter without removing the lid, and to save the material and weight of the lid body, which is desirable.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the small groove animal protective cover of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a usage state of the small groove protective cover for a gutter, in a state of covering the gutter installed on a road shoulder 24 of a road. The gutter small animal protection lid 1 of the present embodiment is a rising wall that prevents small animals from entering the lid body surface along the roadside side edge 5 of the flat plate-shaped lid body 2 that covers the opening of the gutter 20. 3 is integrally molded with concrete. The rising wall 3 of the present embodiment includes a vertical portion 6 that vertically rises from the road shoulder side edge 5 and an inclined portion 7 that is inclined outward from the vertical portion. However, the rising wall 3 may have a shape that does not allow small animals to easily climb over the upper surface of the lid body from the road shoulder 24, and may have a vertical shape as a whole, but has an inclined portion that is inclined outward. Is desirable. The inclined portion may be configured such that the entire rising wall inclines from the road shoulder side edge, or the inclined portion may be provided from the road shoulder side edge, and the vertical portion may be provided subsequently. Furthermore, a combination of inclined portions having different inclination angles may be used.

Further, the lid body 2 is formed with an opening 8 for cleaning so that the inside of the side groove can be cleaned without removing the lid. In this embodiment, two cleaning holes 8 are formed in a rectangular shape, but the shape and the number thereof are arbitrary. The cleaning hole 8 is not always intended only for cleaning, and by providing the hole, it is possible to save the concrete material of the small animal protection lid for the gutter and to reduce the weight thereof, thereby reducing the cost. Can be reduced. However, the cleaning hole 8 is not always necessary and may not be formed. Alternatively, two kinds of gutter small animal protective lids having cleaning holes and gutter small animal protective lids having no cleaning holes may be prepared, and the gutters having cleaning holes at predetermined intervals may be arranged in combination. Good.

Further, in the present embodiment, notches 10 for inflowing rainwater are provided at both ends of the lid body 2 on the road surface side so that rainwater and the like can flow from the road surface 25 into the ditch, as shown in FIG. , A rainwater inflow hole is formed at the connecting portion of the adjacent gutter small animal protection lids. However, the rainwater inflow notches 10 do not necessarily have to be provided at both ends, and any number may be formed at any position as long as it is a position communicating with the road side end of the lid body and communicating with the inside of the gutter. Further, in the present embodiment, the rainwater is made to flow in from the road surface, but if necessary, a rainwater inflow notch may be formed in the road shoulder side edge portion as well. Alternatively, do not provide notches for rainwater inflow on all of the individual gutter small animal protection lids,
The rainwater inflow notch and the rainwater inflow notch may be arranged in an appropriate combination. In addition,
Side wall engaging notches 9 are formed in the longitudinal direction by the width of the side wall so as to engage with the upper surface of the side wall 21 of the side groove 20 at both side edges of the lower surface of the lid body 2.

The gutter small animal protection cover 1 formed as described above, as shown in FIG. 1, has side walls 21 and 21 of a gutter 20 laid on a shoulder 24 of a road that passes through mountainous areas or wilderness.
The side wall engaging notch 9 is simply placed on the side wall 2
The opening of the side wall 20 can be covered by engaging with 1, 21. With the above configuration, a small animal reaching the road shoulder from the habitat is disturbed by the rising wall 3 of the gutter lid 1 and cannot go out on the road, so there is no fear of being run over by a vehicle on the road surface.
Small animals can be effectively protected from traffic damage. In the present embodiment, since the rising wall formed along the side edge of the lid on the road shoulder side has an inclined portion on the outside, even if a small animal tries to climb over the rising wall, it falls at the inclined portion. Therefore, it is possible to reliably prevent the vehicle from entering the road surface.
In addition, the small animal protection cover 1 for a gutter of the present invention has a rising wall provided on the shoulder side of the gutter cover, so that it not only fulfills the small animal protection function, but also, for example, in a gutter laid on a road such as a residential land or farmland. When applied, it can act as an earth retaining member, and can function as both a gutter lid and an earth retaining wall.
