Abstract
The invention discloses a vacuum tube noise reduction device for offshore piling. The device comprises a steel cofferdam, wherein a plurality of air tubes which are arranged in the circumferential direction are arranged on the inner wall of the steel cofferdam; vacuum tubes which are spirally and closely arranged are arranged on the outer wall of the steel cofferdam; the absolute pressure in the vacuum tube is 0 to 101.325KPa. The device has the advantages that noise reduction is realized during the piling process through double means of a plurality of layers of bubble curtains and the vacuum tubes, the structure is simple, the device is easy to realize, the cost is low, noise pollution can be effectively reduced during offshore piling construction, and the device is beneficial to protecting a marine ecosystem and keeping the balance between new energy development and ecological environment.
Description
Technical field
The present invention relates to a kind of noise reduction apparatus, particularly a kind of noise reduction apparatus of noise being subdued for marine guidance piling work progress.
Background technology
At present, the project such as offshore wind farm, bridge spanning the sea, port construction both at home and abroad mostly need to be carried out in predetermined maritime area underwater pile driving construction.The high-decibel noise that underwater pile driving construction produces has a strong impact on living in the biology generation around of this marine site, 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 the problem that industry is needed solution badly.
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 the vacuum tube silencing means of the marine guidance piling of firm and durable.
The technical solution adopted for the present invention to solve the technical problems is:
A vacuum tube silencing means for marine guidance piling, comprises steel cofferdam, and the outer wall of described steel cofferdam is provided with compact arranged in the shape of a spiral vacuum tube, and the absolute pressure in described vacuum tube can be set to 0-101.325KPa as required.
Described vacuum tube is double-layer stainless steel or pvc pipe.
The inwall of described steel cofferdam is provided with some tracheaes that are circumferentially arranged, and described tracheae is provided with the abscess that emits that produces Bubble Heavy Curtain in piling construction process, and described tracheae is connected with air compressor machine by appendix.
The invention has the beneficial effects as follows: the present invention adopts MLV curtain and the realization of vacuum tube two methods to subdue the noise in piling process; simple in structure; easily realize; cheap; can effectively reduce the noise pollution in marine guidance piling work progress; contribute to protect marine ecosystems, keep the balance between new energy development and ecological environment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is stereoscopic mechanism schematic diagram of the present invention;
Fig. 2 is sectional view of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of vacuum tube silencing means for marine guidance piling, comprise steel cofferdam 1, the outer wall of described steel cofferdam 1 is provided with compact arranged in the shape of a spiral vacuum tube 2, absolute pressure in described vacuum tube 2 can be set to 0-101.325KPa as required, this vacuum tube 2 is double-layer stainless steel or pvc pipe etc., and the mouth of pipe of vacuum tube is used the obturator sealings such as vacuum pipe ball valve or flange.The inwall of described steel cofferdam 1 is provided with some tracheaes that are circumferentially arranged 3, and described tracheae 3 is provided with and emits abscess 4, and described tracheae 3 is connected with air compressor machine 6 by appendix 5.
Carry out before marine guidance piling construction, with vacuum air pump, first vacuum tube 2 is evacuated to vacuum negative pressure condition (in pipe, absolute pressure can be set as required), then vacuum tube silencing means integral lifting of the present invention is arrived to stake position, be placed on sea bed face.In piling process; by air compressor machine 6, toward the interior inflation of tracheae 3, air forms MLV curtain by emitting abscess 4 to emerge, at the inner air isolation layer that forms of steel cofferdam; reduce noise; the vacuum tube 2 of steel cofferdam outside further plays vacuum insulating sound deadening simultaneously, simple in structure, easily realizes; cheap; can effectively reduce the noise pollution in marine guidance piling work progress, contribute to protect marine ecosystems, keep the balance between new energy development and ecological environment.
