Net for protection of buried pipework e.g. electric cable, has set of meshes that is formed by connections between segments, where segments of set of chords of chain are spaced in frame direction with variable spacings over width of net

摘要

The net has a set of meshes that is formed by connections between segments (221-226) of a set of chords of chain (22) and a set of chords of a frame (24). The segments of the set of chords of the chain are spaced in a frame direction (X-X) with variable spacings over a width of the net. Each cord of the frame is formed over an entire length of the net in a chain direction (Y-Y) with a constant spacing (2) over the length of the net. The set of chords of the chain are made as single-piece, and the set of chords of the frame is interrupted.
