A method for protection of underwater work zone against effect of water flow includes installation of at least one means for suppression of water kinetic energy under water near the underwater work zone at minimal possible distance as to be no bar to handling of works. As means for suppression of water kinetic energy one uses water-gas, preferably water-air, bubble curtain formed round the work zone with aerator of water medium as a pipeline preferably perforated, connected to source of gas, preferably air, with increased pressure. Level of volumetric disperse gas content of curtain is set depending on velocity of flow and pressure of water, depth of underwater works, but not less than 20%. |
