<p><P>PROBLEM TO BE SOLVED: To provide an animal intrusion prevention fence capable of coping with hole digging by animals. <P>SOLUTION: In the animal intrusion prevention fence for which a fence body comprising a wire net using crimped wires is fixed between a plurality of columns, the wire net is composed by arranging vertical lines 2 and horizontal lines 3 with wavy irregular parts vertically and horizontally in parallel. The vertical line 2 is inserted to the irregular part of adjacent two or more horizontal lines 3 shifted by a half pitch and engaged at the upper and lower parts. The two or more horizontal lines 3 are turned to one set, the adjacent sets of the horizontal lines 3 are separated by 3 pitches or longer from each other, and the wire net is deformable into a parallelogram. One set of two or more side vertical lines 2 and one set of horizontal lines 3 are entangled to form a four-side frame 6, and the four-side frame 6 is formed at both side parts of the fence body. The lower end parts of the respective vertical lines are inserted to the irregular part of at least three adjacent horizontal lines 3c at the lower end parts at an interval with the shift of 1.5 or 2.5 pitches and engaged, and the at least three horizontal lines 3c at the lower end parts are buried underground together with the lower end parts of the vertical lines 2. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
