Polygonal double-layer frame airbag underwater piling noise reduction and dust prevention device

Abstract

The invention belongs to the field of marine engineering vibration and noise, and provides a polygonal double-layer frame airbag underwater piling noise reduction and dustproof device, which includes an external air compressor, an airbag, and inner and outer steel horizontal and vertical support rods. Double-layer frame, the inner and outer frames are respectively connected by horizontal and vertical struts through pipe clips, and are arranged in regular polygons in the circumferential direction of the pile foundation according to the construction arrangement. The inner and outer frames are connected by horizontal struts through tube clips. The air bag is arranged between the inner and outer frames, and the frame is connected with the frame through a prefabricated lock on the air bag, and the external air compressor is connected with the upper part of the air bag. The invention has simple structure, is stable and durable, can be flexibly combined, disassembled and assembled for many times, has designability, and has good sound absorption and noise reduction effect. Helps maintain ecosystem balance.

Description

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