Description

Silt protector with improved anti-fouling properties

The present invention weaving a new anti-fouling film mixed with brass yarn KS standard polyester fabric (geotextile fabric) of the existing anti-fouling film membrane and to prevent fouling through the attachment of marine organisms and formatting during long-term installation in water The present invention relates to an antifouling film having improved antifouling properties such that the net function of the protection film is normal and stable for a long time.

In general, when dredging / building / reclamation works such as dredging / building / reclamation work are performed on rivers, shores or seas, soils containing soil or suspended matter are generated, and in order to prevent such soils from spreading from the construction area to surrounding waters. Antifouling film will be installed. In other words, the anti-fouling film prevents the spread of floating sands generated during the dredging / building / reclamation work such as dredging / building / reclamation work on the river, coast or sea.The membrane body is made of synthetic fiber, Is fixed.

This anti-fouling film is the last reduction plan that can prevent the spread of earth and sand in the sea works, and is mandatory at most construction sites for solving civil complaints.

However, the antifouling film has a high initial design and installation cost, and the maintenance cost is significantly lower than that of the initial design and installation cost, so that only the maintenance of the visual inspection level is usually performed, and thus many problems are generated.

In particular, antifouling membranes prevent the distribution of seawater due to the attachment and habitat of adherent marine organisms (e.g. seaweed, shellfish, etc.) when they are installed in water for a long time, and the attached marine organisms proliferate, thereby increasing their weight. As a result, the subsidence of the floating body or the tearing of the membrane occurs a lot, which is inefficient and economical. In detail, the Applicant found that the field condition during the research service for the increase of the anti-fouling effect shows that when the anti-fouling membrane is installed for a long time, the membrane body is degraded to the habitat of marine life by floating or adherent organisms, thus losing its unique function. In addition, it was confirmed that phenomena such as immersion of the floating body and opening / tearing of the membrane body occurred due to the load of the attached organism.

In addition, the technology of publishing patent documents on membranes of existing antifouling films is not practical in the field, and most construction sites comply with the standard specifications for using them as materials of KS standards. There was no case where this was applied.

As an example, Korea Registered Utility Model No. 20-0359264, "Anti-floor type antifouling film that has been devised for countermeasures against bad weather and adherent organisms," connects a plurality of contact media with a greater specific gravity than water on the surface of the membrane in a vertical line. The contact curtain is formed to stress the adherent organisms by shaking due to algae, blue or wind, and upon inundation, the membrane is folded according to the folding of the contact curtain so that it can be cleaned up. The technology is published to solve all problems simultaneously and to facilitate reuse.

In addition, Korean Patent No. 10-0811808, "Anti-contamination film that can prevent the growth of marine organisms through electric shock," is attached to the surface of the membrane, and the marine organisms that inhabit the surface of the membrane by electric shock and electrolysis. Induces migration through chemical shock caused by hypochlorous acid, which prevents its formation, thereby preventing damage to the membrane. Also, the generation of hypochlorous acid is contained in seawater, which can cause clogging of membranes. Techniques have been published that allow the indirect treatment of marine pollutants by oxidizing the pollutants.

As described above, these prior arts have not been practically applied at the construction site due to the poor practicality of the site.

ㅇ Content

-Globally, the use of copper alloys for aquaculture nets is increasing to reduce environmental pollution caused by marine aquaculture to ensure a sustainable future and to improve the productivity and profitability of aquaculture.

-Brass fishing nets can be used for 6 years or more depending on the installation environment, and 100% recycling is possible after use. This is not only economical but also contributing to the reduction of CO2 emissions as well as protecting the marine and coastal environment.

-Eco-friendly certification for copper alloy material

● 2010.09. Eco-friendly copper alloy material, green technology certification (Ministry of Environment)

● 2011.02. Registered antimicrobial solid substance (US EPA)

● 2011.03. Certification of material parts related to drinking water (NSF / ANSI 61)

In addition, Figure 9 illustrates a copper alloy cage net, Figure 10 shows the results of experiments on the prevention of aquatic organisms adhesion between brass fishing nets and other material fishing nets.

As described above, the membrane body 100 according to the present embodiment includes the membrane body 120 in which the brass yarn 121 is mixed and woven, and thus, the brass yarn 121 dissolves ions in seawater to perform antimicrobial activity. As the organism is prevented from adsorbing / formatting the membrane 100, and the damage of the membrane can be reduced through a continuous antibacterial action (approximate duration of the effect depending on the thickness of the brass sand) for about two years, In addition to maintaining the performance of the antifouling film, the brass of the antifouling film can be recycled when the antifouling film is dismantled upon completion of construction, thus reducing the initial installation cost.

In other words, the existing antifouling film and its members are mostly classified as industrial waste at the time of demolition, resulting in treatment costs. In addition, due to aquatic attachment organisms, additional waste treatment costs are incurred due to the increase in weight of adherent organisms during disposal, as well as complaints caused by odors when lifting from water to land.

In comparison, the membrane body 100 of the antifouling film according to the present embodiment can reduce costs through recycling of the antifouling membrane by lowering the degree of attachment / formation of marine attachment organisms by applying a brass material.

In addition, the membrane body 100 according to the present embodiment minimizes the risk of breakage due to increased rigidity due to the mixed weaving of the brass, and prevents the flying phenomenon of the antifouling film, as described above, about 30% of the initial weight at the initial installation. Can be recycled, thereby reducing the cost of waste disposal.

The floating body 200 provides a double buoyancy force to the membrane body 100 through the air tube 210 and the synthetic resin hollow body 220,
An upper end of the membrane body 100 mounted on the air tube 210 of the floating body 200 is formed of the soft connecting membrane 110, and the connecting membrane 110 is formed along the curved surface of the air tube 210. As it is mounted while bending freely, the weight of the membrane 100 is transmitted to the contact surface with the air tube 210 through the connecting membrane 110 is minimized, and the center of the lower center of the air tube 210 is minimized. While the weight of the membrane 100 is not transmitted, the synthetic resin hollow body 220 supports the air tube 210 about the lower portion 221 of the flat plate shape, and thus, the membrane body of the floating body 200 ( Antifouling film with improved antifouling properties, characterized in that the buoyancy for 100) is increased.
