Description

  The present invention invades agricultural land, eats and destroys crops that have been planted, or invades pests that dig up and destroy the ground surface where plants such as lawns are planted. Underground infestation pest prevention fences that are effective in preventing invasion of pests such as sharks that enter the intrusion prevention target area from below the bottom of the fence by digging a hole in the ground of the boundary Further, the present invention relates to a pest invasion prevention fence provided with the underground invasion pest prevention fence.

  Pests such as cormorants dig up the ground surface to invade and devour crops such as crops, lawns, flowers, and other planted plants, and prey on earthworms and other creatures that inhabit the ground. Damage the planting plant by roughening the leveling itself. Therefore, conventionally, in order to prevent the invasion of harmful pests, various intrusion prevention fences are installed at the boundary (outer peripheral area) of the target area for the prevention of harmful pests. However, there have been many cases in which harmful beasts such as sharks dig into the ground below the lower edge of the intrusion prevention fence from the outside of the intrusion prevention fence and thereby invade the intrusion prevention target area.

  Beasts disclosed in Patent Literature 1 as an intrusion prevention measure for harmful animals that invade the intrusion prevention target area by digging the ground below the lower edge of the intrusion prevention fence from the front of the intrusion prevention fence as described above There is a fence. This beast fence has a structure including struts erected on the ground at intervals, and a fence main body stretched on these struts. The fence main body has a vertical vertical portion that rises substantially vertically, It is composed of an underground vertical portion that is vertically embedded in the ground from the lower end of the vertical portion, and an underground horizontal portion that extends in the horizontal direction from the lower end of the underground vertical portion. And the installation of the fence for the beast is made by excavating a slot having an opening of a size that can accommodate the underground horizontal part of the fence at the boundary of the target area for the prevention of harmful animal invasion, and the underground horizontal part at the bottom of the slot The horizontal part of the ground is fixed with an anchor.

  As described above, the fence for animals disclosed in Patent Document 1 includes an underground horizontal portion extending in the horizontal direction from the lower end of the underground vertical portion. Even if you go digging directly under the ground from the front of the part, you will not be able to dig any further because there is a horizontal part in the middle and give up to dive under the fence.

  Hereinafter, embodiments of the present invention will be described in detail. FIG. 1 is a diagram showing a schematic configuration of a fence for preventing pest invasion according to the present invention. FIG. 1 (a) shows an upper fence body 30 and FIG. 1 (b) shows a lower fence body 10. FIG. 2A is a partially enlarged view of the upper fence body 30, and FIG. 2B is a partially enlarged view of the lower fence body 10. The fence for preventing pest invasion includes an upper fence body 30 shown in FIG. 1 (a) and a lower fence body 10 shown in FIG. 1 (b). A vertical bar 12 positioned below 14 is buried in the ground to fix the lower fence 10, and the lower part of the upper fence 30 is fixed to the upper part of the fixed lower fence 10 as will be described in detail later. It is a configuration.

  As shown in FIG. 1A, the upper fence body 30 includes a plurality of (14 in the figure) vertical bars 32 arranged in the horizontal direction (arrow X direction) at a predetermined interval P1, and the vertical direction (arrows). A plurality (eight in the figure) of horizontal bars 34 arranged at a predetermined interval P2 in the Y direction) are provided. The vertical bars 32 and the horizontal bars 34 are arranged orthogonally. As shown in FIG. 2A, at the intersection 36 between the vertical bars 32 and the horizontal bars 34, the vertical bars 32 and the horizontal bars 34 are joined together by welding or the like, and formed in a lattice shape as a whole. It is a configuration. The distance P1 between the vertical bars 32 and the vertical bars 32 and the distance P2 between the horizontal bars 34 and 34 depend on the size of the body of the pest that prevents intrusion, and is formed at the intervals P1 and P2. The size of the space where the beasts cannot pass through. Here, P1 = 150 mm and P2 = 110 mm. In addition, the vertical bars 32 and the horizontal bars 34 have an appropriate strength that is not broken or easily bent by a harmful animal to be invaded. Here, a reinforcing bar using a galvanized iron material of Φ6 mm is used. Used.

  As shown in FIG. 1B, the lower fence body 10 includes a plurality of (27 in the figure) vertical bars 12 and a plurality of vertical bars 12 arranged in the horizontal direction (arrow X direction) at a predetermined interval P3. One horizontal bar 14 is arranged at the upper end of the bar 12 and one horizontal bar 14 is arranged at a predetermined interval P4 in the downward direction (opposite direction of the arrow Y), that is, a plurality of vertical bars 12. The two horizontal bars 14, 14 are arranged in the range of the interval P4 from the upper end of the lower side as shown in FIG. 2B, and the vertical bars 12 and the horizontal bars 14 are welded to each other at the intersection 16 or the like. It is the structure combined by. The vertical bars 12 below the horizontal bars 14 are extended portions 12a that extend downward by a predetermined length. In FIG. 1B, the two horizontal bars 14 are arranged within a predetermined range from the upper ends of the plurality of vertical bars 12, but the number of the horizontal bars 14 is limited to two. If the strength and function as the lower fence body 10 are maintained even if only the upper part of the plurality of vertical bars 12 is supported by one horizontal bar 14, the vertical bars 12 are 1 It may be a book. Further, in order to increase the support strength of the plurality of vertical bars 12, at least two or more horizontal bars 14 may be disposed within a predetermined range from the upper part of the vertical bars 12. Here, the vertical bar 12 below the lower horizontal bar 14 is an extended portion 12a extended to a predetermined length L.

  The length L of the extending portion 12a is different depending on the type of the pests, the state of the soil where the pest intrusion prevention fence is installed, etc., but here, L = 390 mm. In addition, the size of the interval P3 between the vertical bars 12 and the vertical bars 12 of the lower fence body 10 and the interval P4 between the horizontal bars 14 and 14 is such that a pest that digs in the ground cannot pass through. The length P3 is smaller than the body size of the pest, and particularly the interval P3 between the vertical bars 12 and 12 of the extending portion 12a is strong enough that the vertical bars 12 are bent by the invading pest and the interval P3 does not easily spread. It is necessary to use the reinforcing material 12. Here, P3 = P1 / 2 = 75 mm, P4 = 110 mm, and the longitudinal reinforcing member 12 and the transverse reinforcing member 14 are made of galvanized iron material having a diameter of 6 mm. The galvanized steel bar is excellent in corrosion resistance in the soil.

  As shown in FIG. 3C, the extension part 12a of the lower fence body 10 having the opening width P5 is first embedded in the ground surface 51 on the outer periphery of the area where the infestation of the harmful animals is prevented. A lower fence installation groove 52 is provided. The depth of the lower fence installation groove 52 is substantially equal to the length L of the extending portion 12a of the lower fence body 10. However, since the horizontal bar 14 is not fixed to the extending portion 12a of the lower fence body 10, the vertical bar 12 can be inserted into the soil within a range in which the horizontal bar 14 is not greatly deformed. The bottom of the groove 52 is not necessarily flat and may have some unevenness.

  Next, the extension part 12a of the lower fence body 10 is inserted into the lower fence installation groove 52, and the lower fence body 10 is temporarily installed. Thereafter, the lower fence body 10 is set in a vertical state, and the soil generated when the lower fence installation groove 52 is dug into the lower fence installation groove 52 as shown in FIG. While being fixed, the embedded soil surface 54 is formed by the soil in which the lower rail installation groove 52 is embedded. In addition, when the soil of the part which installs the fence for prevention of pest intrusion is sandy soil etc. and the vertical bar material 12 of the lower fence body 10 can be inserted easily, a lower fence body is not provided, without providing the lower fence installation groove | channel 52. The lower fence body 10 may be installed by directly inserting 10 extending portions 12a into the ground. Moreover, it is also possible to drive the extending portion 12a using a hammer or the like not in sandy soil but in normal soil.

  Next, as shown in FIG. 4 (c), the two horizontal bars 14, 14 located at the upper part of the lower fence body 10 overlap with the two horizontal bars 34, 34 at the lower part of the upper fence body 30, respectively. The vertical bars 12 of the lower fence 10, the vertical bars 32 of the upper fence 30, the horizontal bars 14 of the lower fence 10, and the horizontal bars 34 of the upper fence 30 are fastened with a fastening jig such as a fastening band ( By fastening with (not shown), the upper part of the lower fence body 10 and the lower part of the upper fence body 30 are fixed to each other.

Since the lower part of the body 30 is bound and fixed with a binding band, if the outer periphery of the target area for the prevention of pest invasion is surrounded by the fence for preventing the invasion of harmful pests, the depth of the basement of the target area for the prevention of pest invasion It will be surrounded by the extending portion 12a of the L lower fence 10. As a result, even if there is a pest that digs a hole from the outside of the fence for preventing pest intrusion, such as a spider, and enters the pest intrusion prevention fence, there is the extending portion 12a, so that the intrusion is made further. Give up. Moreover, even if a hole is dug to the lower end of the extending portion 12a, the head is moved up and down when digging in the ground. The lower end of the muscle material 12 will hit the head and body of the harmful animal, which will also cause pain to the head and body, and in some cases damage the head and body. The beast can abandon further digging in the ground and prevent further penetration of the pest into the soil.

  Further, as shown in FIG. 5 (a), the lower end of the extending portion 12a of the lower fence body 10 is sharpened sharply to further prevent the invasion of harmful animals that dig into the ground below the lower end of the extending portion 12a. Play. Further, as shown in FIG. 5 (b), the sharply sharpened portion of the extending portion 12a is bent in the direction in which the harmful animal invades, thereby further exerting an effect of preventing the harmful animal from entering.

  As described above, since the vertical bar 12 of the extending portion 12a of the lower fence body 10 is in the soil and has a function of preventing the invasion of harmful animals, the lower fence body 10 itself prevents underground invading harmful animals. Will constitute a fence. Therefore, the lower fence body 10 can be used as an underground infestation pest prevention fence as an existing pest invasion prevention fence. That is, a lower fence installation groove 52 as shown in FIG. 3C is provided on the ground where the lower edge of the pest intrusion prevention fence installed on the existing ground is located, and the lower fence body is provided in the lower fence installation groove 52. 10 for extending the existing pests by embedding the extended parts 12a or inserting the vertical bars 12 of the extended parts 12a of the lower fence 10 into the ground where the lower edge of the fence for preventing pests is located. The lower fence body 10 can be installed at the lower edge of the fence. Thereby, it is possible to reliably prevent the invasion of the harmful animals trying to enter the invasion prevention area while digging the soil below the lower edge of the harmful animal intrusion prevention fence installed on the ground.

  As described above, the lower fence body 10 has a plurality of vertical bars 12 arranged at predetermined intervals in the horizontal direction, and a predetermined range in the vertical direction within a predetermined range from the upper end of the vertical bars 12 downward.
