Dredging antifouling system

Abstract

The invention discloses a dredging antifouling system which comprises a plurality of bubble antifouling units, and each bubble antifouling unit comprises an air compressor unit, a surge tank and a plurality of perforated aeration pipes; an air outlet of the air compressor unit is connected with an air inlet of the surge tank through an air guide pipe, an air outlet of the surge tank is connected with air inlets of the perforated aeration pipes through a plurality of flexible connecting pipes, and a plurality of aeration holes arranged in rows are formed in the outer walls of the perforated aeration pipes in the circumferential direction; the perforated aeration pipes of the plurality of bubble antifouling units are arranged around the periphery of the dredging area, and every two adjacentperforated aeration pipes are sequentially connected in series through a buckle assembly. According to the invention, the gas supply quantity can be increased, the strength of a circulating flow fieldin a dredging area is enhanced, the pressure intensity required by bubble generation can be ensured, and the bubble generation rate is improved.

Description

technical field [0001] The invention relates to the technical field of dredging and antifouling, in particular to a dredging and antifouling system. Background technique [0002] Dredging works refer to the earth and rock works carried out to widen and deepen the water area by using dredgers or other machines and manual underwater excavation. During the process of dredging, transporting mud, and blowing and filling overflow, the disturbance and diffusion of the original polluted bottom mud material and non-polluted native soil particles will be intensified, and the suspended dredging produced will easily cause the suspended matter in the water to be released in a short period of time. Increased sharply, polluting the surrounding waters to varying degrees. [0003] At present, the measures to prevent the spread of suspended solids in the dredging process are mainly to install closed geotextile antifouling curtains around the dredging equipment or in the entire dredging area ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned antifouling curtains can control the diffusion of suspended solids to a certain extent to meet the environmental protection construction requirements of dredged waters, however, due to the need to frequently open the antifouling curtains to allow ships to enter and exit the construction area, especially for those undertaking heavy shipping functions In the dredging construction area, the operability and practicability of the anti-fouling curtain are limited, and even the navigation of the ship is hindered
