Abstract
The invention relates to a method for reducing noise generated during underwater piling, in particular to a method for reducing underwater noise by an underwater sound damper with air holes so as to protect ocean organisms when a supporting structure for ocean wind power generation is arranged underwater. The underwater sound damper is arranged around a supporting pile, in the piling process of the supporting pile for supporting ocean wind power generation equipment, the underwater sound damper generates bubbles around the supporting pile, the bubbles rise to form a bubble curtain which surrounds the supporting pile, and noise generated during piling is blocked from transmitting under water by the aid of dispersion action caused by impedance discontinuity. According to the method, the underwater sound damper with the air holes is utilized to generate the bubble curtain so as to reduce the underwater noise, so that the ocean organisms are protected, and certain benefit is realized.
Description
Technical field
The present invention relates to a kind of method of the noise produced while reducing in water piling, thus especially a kind of method of utilizing when ocean used for wind power generation support structure thing is set in water sound dampening device in the leachy water of tool to reduce water-borne noise protection marine life body.
Background technology
When ocean used for wind power generation device support stake is set at present in water, due to the piling noise, the biology in water (as the fish of whale, peripheral plant) can be subjected to disturb injury.
Summary of the invention
The present invention is intended to address the above problem; a kind of method of utilizing sound dampening device reduction water-borne noise in water is provided; thereby it utilizes sound dampening device in the leachy water of tool to form bubble to reduce water-borne noise protection marine life body, and its technical scheme adopted is as follows:
A kind of method of utilizing sound dampening device reduction water-borne noise in water, first supporting pile is set to precalculated position, around supporting pile, sound dampening device in water is set again, finally driven piles, described supporting pile is in the piling process, and in water, the sound dampening device produces bubble around supporting pile, described bubble rises and forms air curtain, described air curtain surrounds supporting pile, utilizes the discontinuous peptizaiton caused of impedance, the propagation of noise in water caused during blocking-up piling.
On the technique scheme basis, in described water, the sound dampening device comprises:
Net, described net is presented the hollow barrel of lower prolongation around supporting pile;
A plurality of bubble-shaped adults, its carry is in described online, and described bubble-shaped adult is provided with pore;
Fastening devices, it is arranged on the lower periphery of described net, for described net is fixed on to sea bottom surface.
On the technique scheme basis, the described buoyancy aid that is mounted with on the net.
On the technique scheme basis, the described resonance device that also is provided with on the net, described resonance device has the resonance frequency of 100 ~ 300Hz scope.
On the technique scheme basis, described host will be comprised of the first stratum reticulare and the second stratum reticulare, and described the second stratum reticulare is paperwrapped in the first stratum reticulare outside, on described the first stratum reticulare and the second stratum reticulare, is equipped with the bubble-shaped adult.
On the technique scheme basis, the cylinder that described supporting pile is hollow, described net also comprises the 3rd stratum reticulare, described the 3rd stratum reticulare is covered on the upper surface of the sea bottom surface that approaches supporting pile.
The present invention has following advantage: support the supporting pile of ocean used for wind power generation equipment in the piling process; in water, the sound dampening device produces bubble around supporting pile; bubble rises and forms air curtain; air curtain surrounds supporting pile; utilize the discontinuous peptizaiton caused of impedance, thus the propagation protection marine life body of the noise caused when blocking-up is driven piles in water.
