A suction bucket type underwater piling noise reduction device and its construction method

Abstract

The present invention proposes a suction barrel type underwater piling noise reduction device and its construction method, comprising a buoyancy ring base floating on the water surface; the buoyancy ring base surrounds the periphery of the pile body; a suction barrel device inserted into the bottom soil; the suction barrel The device surrounds the periphery of the pile body, and the suction barrel device is sealed and connected to the wall of the pile body; the first noise reduction net surrounds the periphery of the pile body; the upper end of the first noise reduction net is connected to the buoyancy ring base, and the lower end is connected to the suction barrel device ; the second noise reduction net surrounding the outside of the first noise reduction net; the upper end of the second noise reduction net is connected to the buoyancy ring base on the water surface, and the lower end is a free end; Place under the surface of the water. The present invention can achieve sufficient noise reduction effect through the first shaped noise reduction block on the first noise reduction net; the second noise reduction net is suspended under the water surface in an umbrella shape to perform secondary noise reduction and suppress sound waves from bottom to top The spread; by setting the suction bucket device, the noise at the water-soil interface during piling is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of underwater piling noise reduction for offshore wind turbines, in particular to a suction bucket type underwater piling noise reduction device and a construction method thereof. Background technique [0002] In recent years, with the rapid development of society and the increasing tension of energy, for the sustainable development of social economy and environment, people gradually turn more attention to sustainable energy. Among them, the huge wind power benefits contained in the ocean attract people's attention its development and utilization. The development and construction of offshore wind farms has increasingly become an important part of the energy landscape of various countries. But inevitably, the construction and operation of offshore projects will generate various types of noise pollution to the marine environment.

Problems solved by technology

[0004] However, the balloons in HSD are all smooth balloons, which do not achieve the optimal effect in terms of noise reduction

And in the design of the noise reduction network, the distribution of noise and the extremely large noise emitted at the water-soil interface are not considered
