본 발명은 석션 버켓 타입(Suction Bucket Type) 고정식 해상 풍력발전기의 석션 버켓 기초에 관한 것으로, 특히, 석션 버켓 기초를 해저에 고정하는 과정에서 석션 버켓 기초의 좌굴을 방지하고, 석션 버켓 기초의 수직도를 보정하며, 석션 버켓 기초를 해저에 시공 후 쇄굴현상을 방지하고, 석션 버켓 기초의 수평으로의 유동을 최대한 억제하는 석션 버켓 타입 고정식 해상 풍력발전기의 석션 버켓 기초에 관한 것이다.The present invention relates to a suction bucket foundation of a suction bucket type fixed offshore wind turbine, and in particular, to prevent buckling of the suction bucket foundation in the process of fixing the suction bucket foundation to the seabed, and the vertical degree of the suction bucket foundation. And a suction bucket type of a suction bucket type fixed offshore wind turbine that prevents crushing after construction of the suction bucket foundation on the seabed and suppresses the horizontal flow of the suction bucket foundation to the maximum.

해상풍력발전의 경우 육상에 비해 동일 풍속 대비 낮은 고도에서 양질의 바람에너지를 얻을 수 있다. 이에 국제적으로 해상풍력발전의 건설이 점차 증가하고 있고 국내에서도 관련기술의 개발의 필요성이 증대되고 있다.In the case of offshore wind power generation, high-quality wind energy can be obtained at a lower altitude than the same wind speed. Accordingly, the construction of offshore wind power is increasing internationally, and the need for development of related technologies is increasing in Korea.

해상풍력 건설을 위해서는 국내여건을 고려한 '강관말뚝기초'와 관련된 기술 개발이 필수적인데, 국내의 상황은 해상풍력발전을 위한 설비개발에만 매진했고 설비를 설치하기 위한 기초구조물 및 해상환경에 대한 연구에는 상대적으로 소홀한 실정이다.For offshore wind power, it is essential to develop technologies related to steel pipe pile foundations considering domestic conditions.The domestic situation is focused on the development of facilities for offshore wind power, and the research on basic structures and offshore environment for installing facilities It is relatively neglected.

해상풍력기초로는 수심에 따라 가장 많이 시공되는 기초형식은 모노파일(Monopile)이며, 수심이 깊어질수록 트라이포드 파일(Tripod pile), 재킷 파일(Jacket pile), 석션 버켓 파일(Suction Bucket pile) 등을 적용할 수 있고, 현재 부유식 해상풍력 구조물도 개발 중에 있다.The most basic type of offshore wind power foundation is monopile. The deeper the depth, the Tripod pile, the jacket pile, and the suction bucket pile. And floating offshore wind power structures are also under development.

이 중 석션 버켓 파일(200)은 도 1 및 도 2에 도시한 바와 같이 석션 압력(Suction pressure)을 이용한 버켓(Bucket)형식 기초로서, 석션 압력을 이용하여 시공하고, 압력 작용 정도에 따라 상이한 거동 특성을 발현한다.Among these, the suction bucket pile 200 is a bucket type basis using suction pressure as shown in FIGS. 1 and 2.

이러한 석션 버켓 파일의 적용 수심은 대략 30m 이하 정도이고, 자중과 석션 압력을 이용하여 설치(직경(D):12 ~ 16m)하되, 해저에 착지 후 압력을 이용하여 설정깊이(L)로 관입하는 등 설치가 간단하여 중장비가 불필요하고, 이에 따라 설치비용이 저렴하다.The suction depth of the suction bucket pile is about 30m or less, and it is installed using its own weight and suction pressure (diameter (D): 12 to 16m), but after landing on the seabed, it intrudes into the set depth (L) by using pressure. It is simple to install, so no heavy equipment is required, and thus the installation cost is low.

그러나 해저에 착지 후 압력을 이용하여 관입시 해저의 장애물(암석 등)에 쉽게 그 형상이 일그러지고, 수직도를 맞추기가 어려운 문제점이 있었다.However, after landing on the seabed, the shape is easily distorted by obstacles (rocks, etc.) of the seabed when intruded by using pressure, and it was difficult to adjust the verticality.

또한 설치 후에도 해류 등에 의한 쇄굴 현상으로 기초 주위의 토사가 유출되어 지지력이 감소하는 문제점이 있었다.In addition, even after the installation, the earth and sand around the foundation due to the crushing phenomenon caused by the current flow, there was a problem that the bearing capacity is reduced.

도 6 및 도 7은 5실시예에 따른 석션 버켓 기초의 설치 과정을 나타낸 것으로, 설명하면 본체(100)는 자중 및 수압에 의해 해저에 관입되는데 이때 도 6과 같이 기울어져 관입되는 것이 보통이다.6 and 7 illustrate the installation process of the suction bucket foundation according to the fifth embodiment. When the main body 100 is inserted into the sea floor by its own weight and water pressure, it is usually inclined as shown in FIG. 6.

즉, 본체(100)의 수직 보정홀(20)과, 이 수직 보정홀(20)과 연결된 펌프(미도시)를 이용하여 본체(100) 내부의 공기를 빼내어 수압으로 본체(100)를 해저에 관입하는 것인데, 보통의 경우 도 6과 같이 본체(100)가 기울어진다.That is, by using the vertical correction hole 20 of the main body 100 and a pump (not shown) connected to the vertical correction hole 20, the air inside the main body 100 is drawn out to bring the main body 100 to the seabed by hydraulic pressure. Intrusive, the main body 100 is inclined as shown in FIG.

따라서, 수직도를 보정해야 하는데, 본 발명에서는 수직 보정칸막이(10)와, 수직 보정홀(20)을 통해 보정할 수 있다. 구체적으로, 수직 보정칸막이(10)의 하단과 해저가 만나면 본체(100)의 내부 공간은 독립적인 다수개의 공간이 형성되고, 본체(100)의 기울어진 정도에 따라 해당 수직 보정홀(20) 개방을 조절하면서 내부의 유체를 배출하면 해당 공간의 압력이 낮아져 해당 공간이 수압에 의해 눌려지면서 본체(100)의 수직도가 보정된다.Therefore, the vertical degree should be corrected. In the present invention, the vertical correcting partition 10 and the vertical correcting hole 20 may be corrected. Specifically, when the bottom of the vertical correction partition 10 meets the seabed, a plurality of independent spaces are formed in the internal space of the main body 100, and the corresponding vertical correction hole 20 is opened according to the inclination degree of the main body 100. When the fluid is discharged while adjusting the pressure in the space is lowered, the space is pressed by the water pressure and the verticality of the main body 100 is corrected.

보정이 이루어지면 수직 보정홀(20)을 모두 개방하여, 본체(100)를 해저에 관입한다. 또는 보정과 동시에 본체(100)를 해저에 관입할 수도 있음이다.
When the correction is made, all of the vertical correction holes 20 are opened to inject the main body 100 into the seabed. Alternatively, the body 100 may be introduced into the seabed at the same time as the correction.

이상 본 발명이 양호한 실시예와 관련하여 설명되었으나, 본 발명의 기술 분야에 속하는 자들은 본 발명의 본질적인 특성에서 벗어나지 않는 범위 내에 다양한 변경 및 수정을 용이하게 실시할 수 있을 것이다. 그러므로 개시된 실시예는 한정적인 관점이 아니라 설명적인 관점에서 고려되어야 하고, 본 발명의 진정한 범위는 전술한 설명이 아니라 특허청구범위에 나타나 있으며, 그와 동등한 범위 내에 있는 모든 차이점은 본 발명에 포함된 것으로 해석되어야 할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will readily occur to those skilled in the art without departing from the spirit and scope of the invention. Therefore, it should be understood that the disclosed embodiments are to be considered in an illustrative rather than a restrictive sense, and that the true scope of the invention is indicated by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof, .
