Title:
NET OF THREE-DIMENSIONAL CONSTRUCTION AND VEGETATION METHOD FOR SURFACE OF SLOPE
Document Type and Number:
WIPO Patent Application WO/1996/035021
Kind Code:
A1
Abstract:
A net of three-dimensional construction which combines the function of a three-dimensional net having a relatively large mesh with the function of a net having a smaller mesh than that of the three-dimensional net, has a good shape retention property, is lightweight and easy to handle, can be manufactured at low cost, and is preferably usable for vegetation nets and the like, and a vegetation method for a surface of slope using the net. Inside and outside net-shaped basic materials (1, 2) are connected to each other by a connecting thread (3) by warp-knitting to form a net of three-dimensional construction. String strips (11, 21) which form respective meshes (12, 22) of the basic materials (1, 2) are constituted by rows of stitches of one or more wales, the mesh (12) of one basic material (1) is made larger than the mesh (22) of the other basic material (2), the connecting thread (3) is laid over the string strips (11) of the basic material (1) and the corresponding string strips (21) of the other basic material (2) to connect them, net mesh spaces (S) are defined by connecting portions (30) formed by the connecting thread (3), and a plurality of small meshes (22) are formed inside the net mesh spaces (S) by the string strips (21) of the basic material (2) having no connecting thread (3).
