Description

Assembly-type man-created fishing reef}

In general, artificial reefs are artificial structures that are installed on the coast or near the sea in order to secure marine resources for coastal fishing grounds, to create spawning and habitat for marine life, and to provide shelter for fry. Artificial reefs can be transformed into various forms, from sinking the first abandoned ships or dropping ground structures into the sea to create habitats, and those designed into hexahedral, cylindrical, and uneven structures to create more efficient habitats. Has been. There are various materials to make artificial reefs, and concrete, ceramic, and steel are used.

On the other hand, depending on the species of fish, the body type inhabited regardless of the artificial reefs, the swimming type inhabiting near the artificial reefs, the contact type inhabiting between or touching the artificial reefs and the artificial reefs There are many types of books, such as the benthic forms that live in the spaces formed below. Some of these species are known to spawn, inhabit and rest or sleep within certain spaces of artificial reefs.

In recent years, fishing and offshore fishing fields have been narrowed due to the establishment of exclusive fishing zones of each country, and fishing catches of fisheries have been drastically decreasing due to illegal overfishing. It is a trend.

Artificial reefs are artificially installed in a sea of about 10 to 50m, and provide a stable habitat or hiding place for marine life such as fish, and also serve as a spawning ground.

Artificial reefs are variously classified according to their structure and material, and the most representative ones are hexahedral concrete reefs. However, such a concrete reef has a problem that the specific gravity can not be properly exhibited when installed on the soft ground.

In addition, due to its material properties, not only alkaline harmful substances are generated but also have a disadvantage in that durability is relatively low.

In addition, steel reefs have a structure in which a plurality of steels are connected to each other so as to have a predetermined shape, so that large artificial reefs are easy to manufacture and have their own specific gravity. However, most of them have a structure in which only frames are formed. Due to this, there is a problem that the efficiency as a habitat or hiding place of marine life such as fish is low.

That is, the interior of the artificial reef is not only to effectively shield the ocean currents, but also there is almost no shade area to block the light, there is a limit to function as a stable habitat or hideout of marine life.

In addition, there is a disadvantage that the possibility of damage by external impact due to the structural characteristics of artificial reefs. This, in turn, results in relatively degrading the functionality and usability of artificial reefs.

In addition, these concrete or steel materials are assembled directly at the production site and brought to the sea by means of transportation, or they are manufactured and assembled in a large place that can be manufactured near the sea. Problems are caused by the cost burden and the increase in the construction period due to the cost burden, transportation costs, and the increase of logistics costs for bringing the artificial reefs to the sea.

The present invention was created to solve the above problems, to provide a prefabricated artificial reef that can not only improve the ease of assembling artificial reefs, structural stability of artificial reefs but also secure a stable habitat or hiding place of marine life. Its purpose is to.

In addition, by closing some sections of structural materials, the area of the structural members is increased and the surrounding area of the structural material is less affected by algae, thus providing a wider space for plankton clustering and algae attachment. Another purpose is to provide artificial reefs.

In order to solve the problems described above, the problem is solved through the following embodiments.
