Description

The present invention relates to a fence installed on a slope such as a slope and a method for installing the fence.

Conventionally, as a fence that can be used on a slope, etc., the lower end of a post is driven into the ground, a pair of upper and lower frame members are attached to the support, and the upper and lower frame members are attached to the upper and lower frame members. A flexible lattice panel comprising a pair of left and right vertical frame members rotatably pivoted, and a plurality of lattice members whose upper and lower ends are rotatably pivoted to the upper frame member and the lower frame member. (Patent Document 1).
However, when installing a fence such as a fence on a slope, it is difficult to drive the posts to the predetermined height to support the fence due to the position of the bedrock in the ground. There was a drawback that the protruding length of the wire became uneven, and it became difficult to fix the crosspieces (horizontal frames, crosspieces, etc.) and wire nets.

In addition, when installing a fence on a slope where trees have only been cut down, the roots of the trees remain in the ground, so it is not possible to drive the posts into the ground at regular intervals, and the horizontal trees do not reach the adjacent posts. I could not.

Conversely, if the distance between the struts is shorter than the predetermined distance, the ends of the crosspieces may protrude from the struts, and there is a risk that the crosspieces cannot be installed without performing work such as cutting off the protruding portions.
