  DESCRIPTION OF EMBODIMENTS Embodiments of an animal intrusion protection fence and its construction method according to the present invention will be described below with reference to the drawings based on examples.

(Example)
1 and 2 are diagrams for explaining one embodiment of an animal intrusion protection fence and its construction method according to the present invention. As shown in FIG. 1 (a), the animal intrusion protection fence 1 of this embodiment has one rectangular wall material 2 or a plurality of sheets in the lateral width direction connected to each other by a binding band 3. It is configured. The wall material 2 is composed of expanded metal (a product obtained by cutting a metal plate into a staggered pattern by a special machine and simultaneously expanding it into a rhombus or turtle-shaped mesh).

  The expanded metal material used in the present invention is preferably a steel material that is galvanized and imparted with high corrosion resistance. For example, when a material having high corrosion resistance such as Daima Zinc (registered trademark name) manufactured by Nippon Steel Corp. is used, the animal intrusion protection fence 1 having excellent durability can be obtained.

  In this specification, with respect to the animal intrusion protection fence 1, the side on which an animal to be invaded from now on is defined as the front side, and the side that prevents the invasion of animals such as a field is defined as the back side. As shown in FIG. 2 (a), the wall material 2 constituting the animal intrusion protection fence 1 has a cross-section as shown in FIG. A folded curved portion 6 is formed. The curved portion 6 is formed in a concave shape on the front side (right side in FIG. 2A) and convex on the back side (left side in FIG. 2A).

  The upper portion of the wall surface material 2 (the portion above the curved portion 6 of the wall surface material 2) is installed as a whole so as to be inclined substantially linearly toward the front side and upward.

  FIG. 2B shows a portion on the lower end side of the curved portion 6 that is folded back so as to warp the bow of the wall surface material 2 (a portion having a predetermined width in the vertical width direction from the lower end 5 of the wall surface material 2. In the specification, this portion is referred to as a “bottom surface portion”.), And the bottom surface portion 7 is in contact with the ground surface 8.

  And among the wall materials 2, the vicinity of the front end and the vicinity of the rear end of the bottom surface portion 7 in contact with the ground 8 is brought into contact with the ground by the anchor pile 9 as shown in FIGS. 1 (a) and 2 (b). It is fastened. That is, the wall surface material 2 is engaged with the hook 9 ′ (see FIG. 1A) of the head of the anchor pile 9, and is fastened to the ground 8 by being driven into the ground. .

  On the back surface of the wall surface material 2 above the curved portion 6, a horizontally arranged belly raising material 10 extending in the lateral direction is in contact. As the urging member 10, a rod such as a round bamboo or a dumb pole (agricultural pole material reinforced with glass fiber: trade name) having an outer diameter of about 2 cm is used. As shown in FIG. 1 (b), the urging member 10 is attached by fitting a substantially S-shaped hook member 11.

  This S-shaped hook material 11 is generally called “escan” (S-shaped hook material) by those skilled in the art, and has a large-diameter annular portion 12 and a small-diameter substantially annular hook. The part 13 is integrally formed. The large annular portion 12 is fitted to the bellows member 10, and the small annular portion 12 is inserted from the back side of the wall surface material 2 to the front side, and a support rope 14 is inserted therethrough. The support rope is made of polyethylene as a material, but may be a chain instead of the support rope.

  As shown in FIGS. 1B and 1C, the support rope 14 is inserted into the hook portion 13 of the S-shaped hook member 11 engaged with the belly raising member 10 and is in contact with the ground 8. 1 is inserted into the annular portion 17 of the S-shaped hook material 11 engaged with the bottom surface portion 7 of the wall surface material 2 and, as shown in FIG. It is stretched with tension. Note that the end portion of the support rope 14 is bound to the annular portion 17 of the small S-shaped hook member 15 or to the hook 9 ′ of the anchor pile 9 driven into the ground 8.

  In this manner, the urging member 10 is brought into contact with the wall surface member 2 by the tension of the support rope 14 by tightly connecting the urging member 10 and the bottom surface portion 7 of the wall surface member 2. The curved state of the curved portion 6 and the upper inclined state of the wall surface material 2 can be maintained against the elasticity caused by the bow of the curved portion 6.

  By the way, the vertical dimension of the wall surface material 2 is determined by the size of the height h of the wall surface material 2. The height h of the wall material 2 varies depending on the animal to be protected. For example, it is about 1 m in the case of a frog, about 2 m in the case of a deer, and about 3 to 4 m in the case of a monkey. In order to increase the height h of the animal intrusion protection fence 1, a vertically long wall material 2 may be used, but another wall material 2 may be added.

  The lateral dimension of the wall surface material 2 may be determined as appropriate, but about 1 m is preferable in consideration of convenience such as transportation of the material of the wall surface material 2. It is preferable that the bottom surface portion 7 has such a length that the lower end 5 of the wall surface material 2 is inserted into the ground and does not cause digging, and is stably in contact with the ground 8. For example, the bottom surface portion 7 preferably has a predetermined width of about 40 cm from the lower end 5 of the wall surface material 2 in the vertical width direction of the wall surface material 2. The inclination angle θ of the wall material 2 with respect to the ground surface 8 (horizontal plane) may be about 60 °, for example.
