Description
인공어초는 인위적으로 수중에 여러가지 모양의 구조물을 설치하여 수산동물 특히 어류와 패조류의 먹이 생물인 플랑크톤과 해조류를 증식케하여 어류와 패조류의 보호 및 먹이와 휴식공간을 제공함으로서 자원을 배양하여 어획량을 늘리기 위한 어장시설물이다. 일반적으로 인공어초는 다른생물로 부터 은폐될수 있어야하며, 인공어초의 설치는 해류의 유동에 저항할 수 있는 강도가 이루어져야 한다. Artificial reefs artificially install various shaped structures in the water to grow planktons and algae, which are food for fish and shellfish, and to cultivate resources by protecting fish and shellfish, and providing food and rest areas. It is a fishery facility to increase catches. In general, artificial reefs should be concealed from other organisms, and the installation of artificial reefs should be strong enough to resist current flow.
그동안의 대부분 인공어초는 콘크리트 어초가 대부분이었다. 콘크리트는 재질이 시멘트와 모래를 배합한 것으로서 해수중에서는 시간의 경과에 따라 콘크리트 구조팽창으로 인한 크랙과 박리현상이 나타난다. 이로 인해 콘크리트 강도는 급격히 저하되어 해수가 그 크랙에 따라 콘크리트 구조물 내부에 침투되어 철근이 해수중에 존재하는 염소이온에 더 빨리 노출되고, 이 황산이온이 시멘트 수화물 중에 많이 존재하는 성분인 강알카리성의 독성이 매우 강한 수산화칼슘과 반응하여 석고를 생성시킴으로서 콘크리트 표면이 연화되어 침식되게 되어 콘크리트 인공어초의 수명을 급격히 단축시킨다. 이를 개선하기 위해 굴껍질을 이용한 환경인공어초를 개발(등록제0200553)한바가 있다. 등록(제0200553)의 고안은 굴껍질이나 조개껍질을 투여하여 미세한 분말가루로 분쇄하여 만들고, 분쇄된 굴껍질에 송진을 첨가하며, 굴껍질과 송진액을 혼합할때 결착력을 높히기위해 가루소금을 굴껍질의 약1/10정도의 부피비율로 가열상태에서 잘저어주는 것으로 고안하였다. 상기 혼합된 환경인공어초 제조방법에 따라 어초 성형을 위한 인공어초 형성틀에 부어 넣어 약5분 정도 상온 건조시킨다. 굳은후 환경인공어초 형성틀을 제거하고 환경인공어초를 해수중에 투여하여 환경인공어초를 더욱 견고하게한다. 상기 제조된 환경인공어초 제조방법을 이용하여 인공어초 형성틀의 형태에 따라서 피라밋형, 사각형, 원통형, 뿔형, 육각형, 반구형 등 다양하게 제작이 가능하다. Most of the artificial reefs during that time were mostly concrete reefs. Concrete is composed of cement and sand. In seawater, cracks and delamination occur due to the expansion of concrete structure over time. As a result, the strength of concrete decreases rapidly, and the seawater penetrates into the concrete structure according to the cracks, and the rebar is exposed to chlorine ions present in the seawater more quickly. By reacting with this very strong calcium hydroxide to produce gypsum, the surface of the concrete is softened and eroded, which drastically shortens the life of concrete artificial reefs. In order to improve this, environmental artificial reefs using oyster shells have been developed (Registration 0200553). The design of registration (0200553) is made by grinding oyster shell or clam shell into fine powder powder, adding rosin to crushed oyster shell, and adding powdered salt to increase binding force when mixing oyster shell and rosin solution. It is designed to stir well under heating at a volume ratio of about 1/10 of the oyster shell. According to the mixed environmental artificial reef preparation method is poured into the artificial reef forming mold for forming the fish reef and dried at room temperature for about 5 minutes. After hardening, the environmental artificial reefs are removed and the artificial artificial reefs are administered in seawater to further strengthen the environmental artificial reefs. By using the environmental artificial reef manufacturing method prepared above, it is possible to produce a variety of pyramid-shaped, rectangular, cylindrical, horn-shaped, hexagonal, hemispherical, etc. according to the shape of the artificial reef forming frame.
본 고안은 환경정화와 어패류의 서식 및 번식을 위한 수산자원 조성용으로 이용되는 굴껍질을 이용한 환경인공어초에 관한 것으로서 실용신안등록(제0200553)의 개선사항이다. 인공어초의 생명은 강도가 그 중심이다. 실용신안등록(제0200553)은 강도를 높히기 위해서 가루소금을 사용하였는데 가루소금보다 강도를 높히기 위해서 황토와 짚분쇄물을 해조분말가루와 혼합하여 주면 강도가 더 높아진다. 그리고 강도를 높히기 위해서 다시마분말을 추가하도록 출원한바 있는데 (실용신안출원: 20-2008-0000202), 보다 강도를 높히기 위해서 황토와 짚분쇄물을 굴껍질 분말가루의 약 1/10 및 1/20정도의 부피비율로 추가하여 가열상태에서 잘 저어주게 되면 강도가 훨씬 높아진다. 이에 따라 굴껍질분말가루와 송진액 그리고 황토,해조분말가루 및 짚분쇄물을 섞은 혼합액을 인공어초 형성틀에 투여하여 건조시키고, 건조시킬때 표면에 해조류가 잘 부착할수 있도록 어초의 표면에 도1에서 표시하듯이 지름 약3-5cm정도 두께의 밧줄(로프)을 부착시킨다. 부착시키는 방법은 송진이 녹은후 식을때 밧줄을 부착하여 어초표면에 2-3cm정도 깊이로 들어가도록 눌러주면 단단하게 고정할수 있다. The present invention is an improvement of the utility model registration (No. 0200553), which relates to environmental artificial reefs using oyster shells used for the purification of fisheries and for the production and reproduction of fish and shellfish. The life of artificial reefs is centered on strength. Utility model registration (No. 0200553) uses powdered salt to increase the strength, but if it is mixed with seaweed powder to improve the strength than powdered salt, the strength becomes higher. In order to increase the strength, it has been filed to add kelp powder (Utility Model Application: 20-2008-0000202), and about 1/10 and 1/20 of the powder of oyster shell in ocher and straw powder to increase the strength. When added to the volume ratio of and stirred well under heating, the strength is much higher. Accordingly, a mixture of oyster shell powder, rosin and ocher, seaweed powder, and straw crushed powder is administered to an artificial reef forming mold and dried, so that algae adheres well to the surface of the fish when drying. Attach a rope about 3-5cm in diameter as indicated in. How to attach can be fixed firmly by attaching a rope when it is cooled after melting the rosin and pressing it so that 2-3 cm deep into the surface.
인공어초의 강도를 높히기위해서 소금대신 다시마분말외에 황토 및 짚분쇄물을 추가한다. 그리고 어초의 표면에 해조류가 잘 부착될수 있도록 밧줄을 투입한다. 황토는 굴껍질의 약 1/10의 양을 투입한다. 황토분말은 굴껍질과 송진이 혼합될때 물질사이의 공극을 없애주는 역할을 하게 된다. 따라서 결착력을 높혀줄수 있다. 황토벽돌을 압착기로 찍어내면 단단하게 되는 이유가 바로 미세한 황토가 물질사이의 공극을 없애주는 원리와 같은 것이다. 다시말해서 송진과 굴껍질의 혼합물의 온도를 높혀 끓여주는 것이 황토의 압착과 같은 효과가 나오는 것이다. 짚분쇄물은 혼합물을 결착시키는 효과가 있다. 어초가 어떤 충격을 받더라도 잘갈라지지 않을뿐만 아니라 부스러지지도 않는다. 짚의 결집효과는 짚의 섬유성분이 혼합물과 섞이면서 결착을 만들어낸다고 할수있다. 전체적인 비율은 굴껍질:송진:황토분말:다시마가루:짚분쇄물=1:1:0.1:0.1:0.05의 비율로 한다. To increase the strength of artificial reefs, ocher and straw grits are added to the kelp powder instead of salt. And ropes are inserted to allow seaweed to adhere well to the surface of the reefs. Ocher puts about 1/10 of the oyster shell. Ocher powder removes voids between materials when oyster shell and rosin mix. Therefore, it can increase the binding force. The reason why the ocher brick is hardened by pressing it is the same principle that fine ocher removes voids between materials. In other words, raising the temperature of the mixture of rosin and oyster shell to boil is the same as the compression of ocher. Straw crushing has the effect of binding the mixture. Whatever the impact is, it doesn't split well or crumble. Straw's aggregating effect is that the fiber content of the straw is mixed with the mixture to create a binding. The overall ratio is the ratio of oyster shell: rosin: ocher powder: shimama flour: straw crushed powder = 1: 1: 0.1: 0.1: 0.05.
어초의 표면에 밧줄을 부착시키는데, 이것은 해조류가 잘 부착할수 있도록 하기 위한 방법이다. 해조류가 부착하는 것은 어초의 표면에 부착하는데, 쉽게 부착이 잘 안되는 경우가 있다. 그러나 밧줄은 해조류의 씨가 잘 부착될수 있는 여건을 가지고 있는데 밧줄 사이사이마다 작은 홈이 있으며 해조류의 씨가 잘 부착한다. 미역이나 다시마의 양식에 있어서 겨울철 씨줄의 부착기로 밧줄을 이용해오고 있는 것도 이 때문이다. 밧줄을 부착하는 방법은 혼합물이 식을때 지름 약 3-5cm정도의 밧줄을 길이 약 10cm정도의 크기로 잘라서 약 2-3cm정도의 깊이로 들어가도록 수작업으로 부착하여 눌러주면 된다. 제작과정에서 온도가 100도씨 이상으로 올라가며 식을때는 서서히 식으므로 식을때 밧줄을 어초의 표면에 2/3정도가 들어갈수 있도록 눌러준다. 길이 10cm정도 밧줄 지름의 약 2/3정도가 송진과 굴껍질 황토 및 다시마가루 및 짚분쇄물의 혼합액에 깊이 들어가 부착할수 있도록 함으로서 해조류의 부착기질이 될수 있다. A rope is attached to the surface of the reef, which is a way to ensure that algae attach well. The algae adhere to the surface of the reefs, which can be difficult to attach. However, ropes have a condition where seaweed seeds can be attached well. There are small grooves between the ropes, and seaweed seeds are attached well. This is why ropes have been used as attachments for winter strings in seaweed and kelp production. When attaching a rope, when the mixture cools, cut a rope about 3-5cm in diameter to about 10cm in length and attach it manually by pressing it into a depth of about 2-3cm. During the manufacturing process, the temperature rises to over 100 degrees Celsius, and when it cools down, it cools down slowly. About 2/3 of the rope diameter of about 10cm in length can be attached to the mixture of rosin, oyster shell loess, kelp powder and straw grinding material, and can be attached to seaweed.
황토와 짚분쇄물을 이용함으로서 인공어초의 강도를 높힐수 있고, 내구연수가 길어지므로서 인공어초의 보수 등 교체에 따른 비용을 절감할수 있으며,By using ocher and straw grinding materials, the strength of artificial reefs can be increased, and the durability of the reefs can be increased, thus reducing the cost of replacing artificial reefs.
인공어초의 표면에 밧줄을 부착하여 해조류의 기질을 제공함으로서 부착율을 높힐수 있으며, 이를통해 먹이사슬을 만들고, 어류 유집의 효과를 증대시킬수 있게 된다. By attaching a rope to the surface of artificial reefs to provide a substrate of algae can increase the adhesion rate, through which it is possible to create a food chain, increase the effectiveness of fish collection.
도1은 굴껍질을 이용한 환경인공어초 도면으로서 동 어초를 제작하기 위해서는 거푸집을 먼저 제작해야하는데, 거푸집의 틀이 완성되면 거푸집에 굴껍질분말과 송진 그리고 해조류 분말, 황토 및 짚분쇄물을 혼합한다. 혼합하는 분말의 비율은 굴껍질분말:송진:다시마가루:황토:짚분쇄물=1:1:0.1:0.1:0.05의 비율로 서서히 혼합하여 저어준다. 이때 시간은 굴껍질과 송진혼합물이 용액이 된후 다시마분말과 황토 및 짚분쇄물을 넣고 sol상태가 된후 1분을 초과하지 말아야한다. 1분을 초과하면 송진의 휘발성물질이 공중으로 기화하여 굴껍질과 혼합되는 정도가 낮아진다. 거푸집틀에 혼합용액을 붓고 약 5-30분 정도 식힌다. 식힐때 밧줄을 부착하게된다. 길이 약10cm정도의 밧줄은 지름(3-5cm)이 약 2/3정도가 어초의 표면속에 들어가 부착될수 있도록 밀어넣고, 완전히 식은후 거푸집을 해체한다. 거푸집을 해체하게 되면 도1의 표면4에서 보듯이 밧줄의 부착기 나타나는데 이 기질에서 해조류가 쉽게 부착되며, 작은 동물성 플랑크톤이 포식자로 부터 은폐할수 있다. 1 is a drawing of an environmental artificial reef using oyster shells, in order to produce copper reefs, molds must first be prepared, and when the mold is completed, the oyster shell powder and rosin and seaweed powder, loess and straw crushed powder are mixed with the molds. . The ratio of the powder to be mixed is slowly mixed and stirred in the ratio of oyster shell powder: rosin: tashima flour: ocher: straw pulverized powder = 1: 1: 0.1: 0.1: 0.05. The time should not exceed 1 minute after the oyster shell and the rosin mixture are in solution and the kelp powder, ocher and straw crushed powder are added to the sol state. If it exceeds 1 minute, the volatile substance of rosin vaporizes into the air and the mixing degree with oyster shell becomes low. Pour the mixed solution into the formwork and let it cool for 5-30 minutes. When it cools, it attaches a rope. Rope of about 10cm in length is pushed so that about 2/3 of diameter (3-5cm) can be inserted into the surface of the reef and can be attached. When the mold is dismantled, as shown on the surface 4 of Fig. 1, a rope attaching device appears, and seaweeds are easily attached to the substrate, and small zooplankton can be concealed from predators.
도1은 본고안에 따른 굴껍질을 이용한 인공어초 구조를 도시하는 예시도이고 도면 주요부분에 대한 부호의 설명은 다음과 같다. 1 is an exemplary view showing the structure of the artificial reef using the oyster shell according to the present invention and the description of the symbols for the main parts of the figure is as follows.
