Description

  The present invention relates to a pest invasion prevention structure and a pest invasion prevention method. More specifically, the present invention relates to a pest invasion prevention structure and a pest invasion prevention method for preventing damage caused by an animal such as a deer or a wild boar entering a crop, a forest, a slope, a slope, or the like.

  In recent years, the problem that food crops such as crops planted in fields, fruits planted in mountain forests, bamboo shoots, etc. are damaged by invading deer and wild boars has been increasing. In addition, both sides of expressways and national roads are sloped, and roads around mountain fields and mountain roads have slopes on the sides, and plants are vegetated to maintain these slopes and slopes. In many cases, however, vegetation plants are becoming increasingly damaged by deer and wild boar. If plants are damaged by damage and the ground is exposed, the ground may be eroded by rain, etc., and the slope and slope may collapse. Therefore, there is a need for means for preventing the invasion of harmful pests such as deer and wild boar.

  As a means of preventing harmful animals from entering fields, mountain forests, slopes and slopes, it is common to provide a prevention fence around the target land. Various types of prevention fences have been proposed by the national and local governments. However, although the prevention fence is relatively easy to install, if a large animal such as a deer or a wild boar comes into contact with the prevention fence, the prevention fence may be deformed or damaged. . In places such as slopes and slopes, even if a prevention fence is provided, there is a possibility of jumping over from the upper side of the slope or slope.

Therefore, as a beast harm prevention device having a great beast harm prevention effect, a plurality of rod-shaped and arc-shaped frame members, and both ends of the frame members are pierced into the ground and the frame members are erected on the ground. There has been proposed a beast damage defense device comprising a net to be installed and a plurality of stops for fixing the edge of the net to the ground (Patent Document 1). In this beast harm defense device, the net is set up in a curved or slanted shape to protect against beast harm by utilizing the nature of the beast that avoids the net, and the beast tries to get over the net. In some cases, the net is entangled with the legs, 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 are erected independently from each other, the pest defense device has a strong contact with the net between the frame members. If the net is entangled with the beast, the beast harm defense device is damaged, and another beast may invade from the damaged portion and cause the beast harm. In this case, although repair is possible, it is necessary to focus on maintenance, such as it is necessary to periodically look at whether the beast harm defense equipment is damaged.

Further, a beast net fence 1 as shown in FIG. 3 of Patent Document 2 has also been proposed. As in Patent Document 1, this animal net fence 1 is in a state where the net knitted fabric 2 is partially lifted from the ground 4, so that the leg foot of the pest can be reliably restrained and the animal prevention function is excellent. (See paragraph [0020] of Patent Document 2).
However, although the net knitted fabric 2 is stretched on the outer surface of the support column 11 that is horizontal to the ground 4, the animal proof net fence 1 is not fixed, but the net knitted fabric 2 is stretched. Because the installed support pillars 11 are not fixed to each other, if the beast is in strong contact with the horizontal support pillar 11, the net is entangled, and the animal fence net fence is damaged, and another beast invades from this damaged part. May occur. In this case, although repair is possible, it is necessary to focus on maintenance, for example, it is necessary to periodically check whether the animal net fence 1 is damaged.

  It is known that if even one pest invades, serious damage will occur in the invaded area. On the other hand, the fields, forests, slopes, slopes, etc., originally, unlike urban houses, have a very large area that needs to be prevented from entering, and in most cases the ground is not level. Therefore, there is a problem that it is difficult to adopt a means that can reliably prevent the invasion of beasts such as a cage and a wall. Therefore, there is a need for a new means that can be installed in fields, mountain forests, slopes, slopes, and the like, and more efficiently prevent the invasion of harmful animals.

In Example 1, it is the photographic image which shows the structure 1 for prevention of harmful animal invasion installed in the slope, and its periphery. It is a photographic image which shows the structure 1 for pest invasion prevention about 2 months after installation of the slope shown in FIG. 14, and its circumference | surroundings.

  Embodiments of the present invention will be described below.

  As shown in FIG. 1, the structure 1 for preventing pest invasion according to the present invention includes a skeleton 2 and a wire mesh 3 attached to the skeleton 2 and fixed thereto. Thus, the strength of the structure 1 for preventing pest invasion can be improved by fixing the frame 2 and the wire mesh 3. In addition, in general prevention fences, for example, a resin net is used as in Patent Documents 1 and 2, but when a large pest such as a deer comes into contact with this net, the limbs of the pest are entangled with the net. If the pests rampage in that state, the prevention fence itself will be damaged. And another pest may invade from the damaged part. On the other hand, in the structure 1 for preventing pest invasion according to the present invention, the wire net 3 is fixed to the frame 2 so that a large pest such as a deer or a wild boar comes into contact with the wire net 3. However, since the pests do not get entangled with the wire mesh 3 and the strength is increased, it is possible to prevent the pest invasion prevention structure 1 from being damaged.

  As shown in FIG. 2, the frame 2 includes a plurality of support frame frames 4 (4 ′, 4 ″) and a plurality of support frame frames 4 (4) arranged in parallel on the ground G.
