Underwater air curtain noise reduction device used in single pile driving process
The invention discloses an underwater air curtain noise reduction device used in the single pile driving process, the underwater air curtain noise reduction device used in the single pile driving process comprises a supporting base, a pile embracing assembly and a plurality of air curtain generation assemblies, the supporting base is provided with a cabin, a vent hole and a water through hole, the vent hole and the water through hole communicate with the cabin, and the pile embracing assembly is connected with the supporting base; the air curtain generating assemblies are connected with the supporting base, the multiple air curtain generating assemblies are distributed at intervals in the vertical direction, and the diameters of air curtains generated by the air curtain generating assemblies are sequentially reduced in the direction from bottom to top, so that the air curtains surrounding the single pile have multiple layers distributed at intervals in the radial direction of the single pile. The supporting base sinks to the seabed in the mode that gas in the cabin and water in the cabin are pumped out, and therefore the installation operation of the air curtain generation assembly is efficiently completed. By arranging multiple layers of air curtains, the noise reduction effect is improved, the number of layers of air curtains close to the top of a single pile is large, the number of layers of air curtains close to the bottom of the single pile is small, and the reasonability of air curtain distribution is improved.
本发明公开了一种用于单桩打桩过程的水下气幕降噪装置，所述用于单桩打桩过程的水下气幕降噪装置包括支撑底座、抱桩组件和多个气幕发生组件，支撑底座具有舱室以及与舱室连通的通气孔和通水孔，抱桩组件与支撑底座相连，气幕发生组件与支撑底座相连，多个气幕发生组件沿竖向间隔分布，且在从下到上的方向上气幕发生组件生成的气幕的直径依次减小，以便环绕单桩的气幕具有沿单桩的径向间隔分布的多层。通过抽出舱室内的气体和抽出舱室内的水的方式，使支撑底座下沉至海底，从而高效地完成气幕发生组件的安装作业。通过设置多层气幕，提高降噪的效果，并且靠近单桩顶部气幕层数多，靠近单桩底部气幕层数少，提高气幕分布的合理性。
