Abstract
The invention discloses a novel steel cofferdam device for eliminating and reducing steel pipe pile noise in offshore wind power building. The novel steel cofferdam device comprises a steel cofferdam, wherein a sulfur-free rubber sound absorption wedge layer formed through extrusion is attached onto the inner wall of the steel cofferdam, rubber hoses distributed in a spiral shape are arranged in the steel cofferdam, air holes are formed in the rubber hoses, compressed air enters positions between the steel pipe pile and the steel cofferdam through the rubber hoses for forming air bubbles to be used as a first sound damping device, the sulfur-free rubber sound absorption wedge layer attached on the inner wall of the steel cofferdam is used as a second sound damping device, the noise vibration generated in offshore fluid during the underground piling construction can be effectively reduced, the production cost is low, the manufacturing is easy, firmness and durability are realized, the ocean ecological system can be favorably protected, and the balance between the new energy source development and the ecological environment can be maintained.
Description
Technical field
The present invention relates to a kind of noise reduction apparatus, the noise reduction apparatus of particularly in a kind of offshore wind turbine foundation piling process, noise being subdued.
Background technology
At present, offshore wind turbine foundation adopts single pile more both at home and abroad, tripod, the base forms such as jacket, and these base forms mostly need to carry out underwater pile driving construction, the construct high-decibel noise that produces of underwater pile driving produces and has a strong impact on living in this marine site biology around, grievous injury and interference marine organisms, destroy marine ecosystems balance, how effectively controlling the caused noise of piling construction in marine wind electric field process of construction impacts, keep the balance between new energy development and ecological environment, become industry and need badly the problem of solution.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides and a kind ofly can effectively reduce the noise vibration producing in the fluid of underwater pile driving when construction coastal waters, cost of production is low, easily manufactures, and the novel offshore wind farm of firm and durable is subdued the steel cofferdam device of steel pipe pile noise.
The technical solution adopted for the present invention to solve the technical problems is:
Novel offshore wind farm is subdued a steel cofferdam device for steel pipe pile noise, comprises steel cofferdam, on described steel cofferdam inwall, be attached with one deck extrusion modling without sulphur rubber wedge absorber layer.
In described steel cofferdam, be provided with the stiffener of some longitudinal extensions.
In described steel cofferdam, be provided with some reinforcing rings.
In described steel cofferdam, be provided with the rubber hose that helical form is arranged, in described rubber hose, be provided with pore.
It is described that without sulphur rubber wedge absorber layer, without sulphur rubber sound absorption, monolithic is stacked forms by some.
The invention has the beneficial effects as follows: in steel cofferdam of the present invention, be provided with the rubber hose that helical form is arranged, in rubber hose, be provided with pore, compressed air is entered between steel pipe pile and steel cofferdam and is formed bubble by rubber hose, as first silencing apparatus, the one deck adhering on steel cofferdam inwall without sulphur rubber wedge absorber layer as second silencing means, the noise vibration producing in the fluid of coastal waters can effectively reduce underwater pile driving construction time, cost of production is low, easily manufacture, firm and durable, contribute to protect marine ecosystems, keep the balance between new energy development and ecological environment.
