<P>PROBLEM TO BE SOLVED: To obtain a rectangular gabion that enables adjustment of a length of a front or rear net without decreasing the degree of tension of a column line forming a rhombic wire mesh. <P>SOLUTION: A front net 3 of a rectangular gabion 1A made of a rhombic wire mesh is formed by vertically disposing column lines 10 of the rhombic wire mesh, and the drawing column lines 10A and 10B in mutually different positions in the front net 3 are coupled to each other with a coupling fitting 14 by being drawn in a direction in which an interval therebetween becomes shorter. Thus, the front net 3 is formed shorter than the rear net 4 so that a shape of the rectangular gabion 1A in a plan view can be formed as a trapezoidal or fan-paper shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
