Noise reduction and dustproof device for polygonal double-layer frame airbag underwater piling

Abstract

The invention belongs to the field of marine engineering vibration and noise, and provides a noise reduction and dustproof device for polygonal double-layer frame airbag underwater piling. The noise reduction and dustproof device for polygonal double-layer frame airbag underwater piling comprises an external air compressor, an air bag, and an inner and outer double-layer frame formed by connectingsteel transverse and vertical support rods, the inner and outer frames are connected by transverse and vertical support rods through pipe clamps, and regular polygonal arrangement is arranged in thecircumferential direction of a pile foundation according to construction arrangement, the inner and outer frames are connected by transverse support rods through the pipe clamps, the airbag is arranged between the inner and outer frames and is connected to the frames through prefabricated locks on the airbag, and the external air compressor is connected to the upper part of the airbag. The noise reduction and dustproof device for polygonal double-layer frame airbag underwater piling has the characteristics of being simple in structure, stable, durable, capable of being flexibly combined, disassembled and assembled multiple times, having designability, and good sound absorption and noise reduction effects, also, turbidity of the local seafloor water body near the pile foundation is effectively reduced because a cofferdam is formed, and maintenance of ecosystem balance is facilitated.

Description

Technical field [0001] The invention belongs to the field of marine engineering vibration and noise, and relates to underwater piling noise and floating dust control, in particular to a polygonal double-layer frame airbag underwater piling noise reduction and dust prevention device. Background technique [0002] Marine engineering and other activities represented by underwater piling construction will cause harm to the ocean, lake mammals, fish and other organisms, affect the sustainable development of fisheries, and disrupt the ecological balance of the environment. Underwater piling is a typical strong impact, which produces multiple pulse-like broadband waveforms of high sound source level, which can cause serious consequences such as hearing damage to mammals in oceans and lakes, and damage to fish internal organs. At the same time, piling makes local waters The turbidity of the water body increases, inhibits the growth of phytoplankton, disturbs the internal system of zoopla...
