Description

TECHNICAL FIELD The present invention relates to a wild animal damage-preventing net-like body that is stretched around farmlands, plantations, etc., to prevent crops, trees, etc. from being damaged by wild animals.

In recent years, the number of wild animals such as wild boars and deer that appear in human settlements has tended to increase. As a countermeasure, wire nets, iron fences, fiber nets, etc. are used to provide shields around farmlands and plantations to prevent wild animals from entering. For example, Patent Document 1 proposes to use a synthetic resin thread for one of a pair of threads and a metal wire for the other to use a net with a metal wire having a predetermined strength as a net for preventing animal damage. there is

On the other hand, in Patent Document 2, a large number of continuous filaments of a thermoplastic synthetic polymer are superimposed on a coarse wire mesh in a mesh shape forming irregular loops, and in the mesh space of the wire mesh, the continuous filaments are formed into a wire mesh. The use of a net-like body protruding from a surface for vegetation is described. In Patent Document 3, a main wire mesh, a fiber layer having a three-dimensional mesh structure in which fiber members are intertwined so as to have meshes smaller than the mesh of the main wire mesh, and the main wire mesh and the fiber layer are engaged. A wire mesh for slope protection is described that has an engaging fabric member that is aligned.
