筛网式消能工已在黑龙江、吉林等省的中小型水利工程中采用。近年来又逐步地在华北、西北的内蒙、青海等省区采用。筛网式消能工的应用范围也在不断发展。1978年绥化地区在“渡槽引渡式跌水”中应用筛网消能工,使工程量节省70%,在“一字闸”中采用了筛 Screen energy dissipater has been used in small and medium-sized water conservancy projects in Heilongjiang, Jilin and other provinces. In recent years, it has gradually been adopted in North China, Northwest Inner Mongolia, Qinghai and other provinces and autonomous regions. Screen-type energy dissipater applications are also growing. In 1978, Suihua applied a screen energy dissipater to the “Extradition-type Aqueduct Displacement”, saving 70% of the project volume.
