Description

최적상태의 진동수주 방파제가 형성된 해양 부유식 구조물{Oscillating water column breakwater based on floating objects}Oscillating water column breakwater based on floating objects

본 발명은 방파제에 사용되는 해양 부유식 구조물에 관한 것이다.The present invention relates to marine floating structures for use in breakwaters.

더욱 상세하게는 방파제로 사용되는 해양 부유식 구조물에 파랑에너지를 줄일 수 있도록 진동수주 및 오리피스가 형성된 진동수주 방파제를 설치하되, 상기 해양 부유식 구조물이 체적의 상태가 되도록 부유식 구조물과 진동수주 방파제 사이의 크기를 제공한 해양 부유식 구조물에 관한 것이다.More specifically, the vibration floating breakwater formed with a vibration order and an orifice is installed in the marine floating structure used as a breakwater to reduce the wave energy, but the floating structure and the vibration receiving breakwater are formed so that the marine floating structure becomes a volume state. It relates to a marine floating structure that provides a size between.

최근, 우리가 삶을 영위해온 육상공간은 인구증가 및 자원확보를 위하여 개발이 이루어져야 하나 더 이상 개발할 여지가 부족해지고 점차 부족해지고 있어, 최근에는 근해의 신도시나 해안을 매립해 사용하는 친수공간, 임해공단 등이 개발되고 있으나, 해안지역은 생태계보존 및 환경보존을 위해 남겨두어야 하는 상황이므로 해안공간을 효과적으로 이용하기 위한 방편이 요구되고 있다.In recent years, the land space we have lived for has to be developed for population growth and resource acquisition, but there is no room for further development, and it is gradually becoming insufficient. Although industrial complexes are being developed, the coastal areas need to be left for ecosystem preservation and environmental preservation. Therefore, methods for effectively utilizing the coastal space are required.

해안공간을 효과적으로 개발하여 사용하기 위하여 부유식 구조물이 사용되고 있으며, 이러한 해양에 설치되는 부유식 구조물은 파랑, 조류 및 바람에 의하여 힘 을 받아 움직이게 되며, 상기 파랑, 조류 및 바람으로 인한 외력이 구조물을 파손시키거나 운동을 유발시켜 작업효율을 떨어뜨리게 된다.Floating structures are used to effectively develop and use the coastal space, and the floating structures installed in the ocean are moved by the force of blue, algae, and wind. It may cause damage or cause movement, which will reduce work efficiency.

상기 파랑은 파고 및 주기에 따라 공진이나 표류운동 등을 유발하여 복원력 상실 등을 유발하여 구조물을 전복시키거나 작업위치의 이탈을 초래하고, 바람은 상부 구조물에 대해서는 동적 효과를 일으키며, 하부구조물에 대해서는 전도모멘트를 작용시키게 된다.The wave causes resonance or drift motion according to wave height and period, causing loss of restoring force, etc., causing the structure to overturn or deviation from the working position, and wind causes dynamic effects on the upper structure, and on the lower structure. The conduction moment is acted on.

이러한, 상기 외력에 의해 구조물에 미치는 영향을 최소화하기 위하여 여러 방법이 제시되고 있다.In order to minimize the influence on the structure by the external force, various methods have been proposed.

상기 외력에 의해 구조물에 미치는 영향을 최소화하기 위하여 제시되는 방법으로는, 방파제의 설치, 구조물 형상의 변화, 운동감쇠를 위한 부가물 설치가 적용된다.As a method proposed to minimize the influence on the structure by the external force, the installation of the breakwater, the change in the shape of the structure, the installation of additives for damping motion is applied.

일반적으로 방파제는 외향으로부터 입사해오는 파랑에너지를 반사시켜 부유식 구조물의 운동을 최소화시키기 위한 것으로 크게 고정식과 부유식으로 구분된다.In general, the breakwater is to minimize the movement of the floating structure by reflecting the wave energy incident from the outward, it is largely divided into fixed and floating.

고정식 방파제는, 부유식 구조물의 전면에 방파 구조가 해저면까지 시공된 형태로서 파랑의 저감 성능 즉, 파랑 제어성이 뛰어나지만, 해저면까지 시공이 이루어져야 하므로 시공에 드는 노력 및 비용이 매우 크게 소요되며, 해수의 순환을 방해함으로써 부유식 구조물의 주변해안에 환경문제를 발생시키는 문제점이 있다.Fixed breakwater is a type in which the breakwater structure is installed on the front of the floating structure to the bottom of the floating structure, and it has excellent wave reduction performance, that is, the controllability of the wave. However, since the construction must be done to the bottom of the floating structure, it requires a lot of effort and cost. In addition, there is a problem of causing environmental problems in the surrounding coast of the floating structure by disturbing the circulation of seawater.

특히, 지반이 약할 경우 침하하거나 기초부분이 세굴되는 현상이 발생할 수 있어 설치할 수 있는 장소가 제한되는 단점을 초래한다.In particular, when the ground is weak, sinking or scrubbing of the foundation may occur, which results in a disadvantage in that the installation site is limited.

부유식 방파제는, 부유식 구조물 전면에 부유체 형태로 설치된 방파제로서, 부유식이므로 고정식 방파제에 비해 시공 비용이 적고 해수 순환이 자유로워 고정식 방파제에 비하여 환경문제가 적지만, 고정식 방파제에 비해 방파 성능이 작은 단점이 있다. 또한 특정 주기영역의 파랑에 대한 소파가 그 주된 목적이므로 성능 발휘에 다소 제한이 발생되는 문제점도 있다.Floating breakwater is a breakwater installed in the form of floating body on the front of the floating structure. Since it is floating type, it has less construction cost than fixed breakwater and frees seawater circulation, so there is less environmental problem than fixed breakwater. There is a small disadvantage. In addition, there is a problem that the performance is somewhat limited because the sofa for the blue wave of a specific period region is the main purpose.

상기 문제점을 해결하고자 발명되는 해양 부유식 구조물인 본 발명은, 부유식 구조물 일측에 파랑에너지를 효과적으로 감쇄시키기 위하여 하측으로 해수가 유입되도록 개구부가 형성된 진동수주와, 상기 진동수주 상측부에 형성된 오리피스와, 상기 진동수주의 일측에 형성된 소파판으로 이루어진 부유식 방파제를 제공하는데 목적이 있다.The present invention is a marine floating structure invented to solve the above problems, the oscillation column formed with an opening so that the sea water flows to the lower side to effectively attenuate the wave energy on one side of the floating structure, and the orifice formed on the upper side of the oscillation column and It is an object to provide a floating breakwater consisting of a sofa plate formed on one side of the vibration frequency.

또한, 상기 부유식 방파제인 진동수주 방파제로 인하여 해양 부유식 구조물이 파랑에너지로부터 가해지는 힘이 줄어들어 해양 부유식 구조물이 파손되는 것을 방지할 수 있는 효과가 있다. In addition, due to the vibration-breaking breakwater that is the floating breakwater, the force applied from the wave energy of the marine floating structure is reduced, thereby preventing the marine floating structure from being damaged.

또한, 해양 부유식 구조물의 부유식 구조물과 진동수주 방파제 등의 크기를 제시함으로써 보다 안정적인 해양 부유식 구조물을 제공할 수 있다.In addition, it is possible to provide a more stable marine floating structure by suggesting the size of the floating structure of the marine floating structure and the vibration-breaking breakwater.
