Stream securing device for hydraulic channel, has line of buoys for forming constant angle between ends of banks, where angle is provided in specific range with respect to flow direction

摘要

The device (1) has a line of buoys (4) extending between an end (4a) located near a bank (10) and another end (4b) located near another bank (20). The line of buoys forms a constant angle (alpha) between the ends, where the angle ranges between 30 degrees and 80 degrees with respect to flow direction. A support (11) comprises a cylindrical guiding mast (12) extending in a vertical sliding direction, and is partially placed in a stream (2) near the former bank.
