PURPOSE:To easily manufacture netting material on site by a method in which plural ropes are arranged vertically and horizontally in a crossing manner at given intervals matching the size of a breakwater structure and the crossing points of the ropes are connected with clampers. CONSTITUTION:Horizontal ropes 1' are set at intervals on a dam, and vertical ropes 1 are crossed in parallel at intervals on the ropes 1'. The crossing points of the ropes 1 and 1' are connected by fitting the ropes 1' into the central curved portions of U-shaped bolts 9 of clips 4, laying plates 8 inserted with the bolts 9 through holes 7 on groove-like recessions of the rops 1, and then clamping nuts 10 connected to the bolts 9. |
