摘要
The present invention relates to a fence capable of coping with a landform change in an area whose landform can be varied by a sand storm in the Middle East or a desert area. A boundary fence has a plurality of fence units, which are formed on a length basis and engaged with one another. The fence units comprises: a plurality of vertical members which are inserted into ground to be installed in an erect position; horizontal members which are engaged with upper and lower ends of the vertical members; support members which are installed in front and rear of the vertical members and engaged with the vertical members to rotate; and a plurality of coupling members which couple the support members with the vertical members. The module type fence units, which are formed on a predetermined length basis, are installed by inserting second vertical members into punch holes, formed in the ground, in an erect position and coupling the fence units with the second vertical members. Therefore, even a border fence of a length of a few to a few tens of kilometers can be quickly installed at reduced costs. Also, even when sand accumulates on the boundary fence by the sand storm in an area whose landform can be varied by the sand storm in the Middle East or a desert area, the disassembly is facilitated by raising the vertical members such that the support member such as a brace member can rotate around the coupling member. Furthermore, since the fence can be reinstalled by punching holes in the ground of a changed landform and installing the fence in the holes, therefore, it is possible to cope with change in a landform because disassembly and reinstallation are facilitated. And maintenance cost and time can be reduced for maintaining the boundary fence.
