Definitions

• the present invention relates, in general, to marine structures, which are installed under the sea, and, more particularly, to a seabed- fixed marine structure which is securely fixed to the seabed by driving it into the seabed to function as an artificial reef which is provided under the sea to produce fisheries resources, and which supports on the upper end thereof a wave power generating apparatus, a wind power generating apparatus, a solar power generating apparatus, a tidal power generating apparatus, a beacon lamp, or a combination thereof, and a method of manufacturing the seabed- fixed marine structure.
• artificial reefs are artificial structures which are installed in coast or near the shore to provide spawning areas and habitat for marine organisms and hiding places for fingerlings with the intention of securing fisheries resources in coastal fishing areas.
• abandoned ships or terrestrial structures were submerged in the sea to produce habitat for fish, and were thus used as artificial reefs.
• artificial reefs have adopted various types of structures, such as hexahedral structures, cylindrical structures, embossed structures, etc., to form habitat more efficiently.
• various materials such as concrete, ceramic, steel, etc., have been used as the material for artificial reefs.
• Such an artificial reef is stationary due to its own weight. Additionally, to more securely maintain the artificial reef at a constant position, a structure in which a separate ground fixture (an H-beam) is provided on the lower end of the artificial reef was proposed in Korean Utility Model Registration No. 338494. In Korean Utility Model Registration No. 417728, an artificial reef provided with an anchor having a reversed trigonal prism shape was proposed. As such, in the case where the ground fixture or the anchor is provided on the lower end of the artificial reef, the movement of the artificial reef by the tide is mitigated somewhat, but cannot be completely prevented. In other words, because there remains the likelihood of movement of the artificial reef by the tide, the artificial reef is not sure to remain at the initial position thereof.
• an object of the present invention is to provide a seabed-fixed marine structure which is securely fixed to the seabed by driving it into the seabed to a predetermined depth to function as an artificial reef which is provided under the sea to produce fisheries resources, so that the seabed-fixed marine structure can always remain at the initial position at which the marine structure was submerged even if a severe external force is applied thereto, thus making post maintenance easy, and a method of manufacturing the seabed-fixed marine structure.
• Another object of the present invention is to provide a seabed-fixed marine structure which is securely fixed to the seabed by driving it into the seabed to a predetermined depth and can conduct various functions, including a function as an artificial reef and a function of supporting on the upper end thereof a wave power generating apparatus, a wind power generating apparatus, a solar power generating apparatus, a tidal power generating apparatus, a beacon lamp or a combination thereof, and a method of manufacturing the seabed-fixed marine structure.
• the upper end of the support column may extend upwards relative to the sea level such that a separate apparatus is supported on the upper end of the support column.
• the separate apparatus may comprise one selected from among a wave power generating apparatus, a wind power generating apparatus, a solar power generating apparatus, a beacon lamp, a tidal power generating apparatus and a fishing deck.
• the seabed- fixed marine structure may further include a light emitting apparatus provided in the artificial reef body, the light emitting apparatus having luminous means for emitting light using external electricity.
• the support column may comprise a steel pipe having a polygonal or circular cross-section. The steel pipe may be filled with concrete.
• the present invention provides a method of manufacturing a seabed-fixed marine structure functioning as an artificial reef, comprising the steps of: striking a steel pipe such that a lower end of the steel pipe is pegged into and fixed to a seabed, thus forming a support column, and fitting an artificial reef body, which is made of a plurality of members and has therein a column insertion space for insertion of the support column, around the support column through the column insertion space of the artificial reef body, and seating a lower end of the artificial reef body onto the seabed.
• the stackable bodies may be fitted around the support column in sequence and are stacked on top of one another.
• the seabed- fixed marine structure according to the present invention is securely fixed to the seabed by driving it into the seabed to a predetermined depth to function as an artificial reef which is provided under the sea to produce fisheries resources.
• a severe external force for example, a force generated by a flood tide
• it can always remain at the initial position at which the marine structure was submerged. Therefore, there is an advantage in that post maintenance thereof is convenient.
• the seabed-fixed marine structure of the present invention which is securely fixed to the seabed by driving it into the seabed to a predetermined depth, can conduct various functions, including a function as an artificial reef and a function of supporting on the upper end thereof a wave power generating apparatus, a wind power generating apparatus, a solar power generating apparatus, a tidal power generating apparatus, a beacon lamp or a fishing deck.
