일반적으로 수중 구조물이 설치된 곳의 바닥은 물의 흐름이 빠르거나 와류현상이 발생되어 수중 구조물이 설치된 곳의 바닥이 패이는 세굴현상이 발생되는데, 이와 같은 세굴현상을 방지하기 위하여 상기 바닥에 사석을 일정 두께로 깔아 세굴을 방지하나, 사석은 일정 크기의 암석을 채취하여 구하기 때문에 자연파괴라는 문제가 따르고 홍수나 태풍 발생시 상기 사석이 유실되는 문제가 있어, 근래에는 첨부한 도면 도 1에 도시한 바와 같은 테트라포드(100)나 도 2로 도시한 콘크리트블럭(101) 또는 도 3으로 도시한 세굴방지망(102;일명 돌망태) 등을 이용하여 세굴을 방지한다.Generally, the bottom of the place where the underwater structure is installed has a rapid flow of water or a vortex occurs, so that the bottom of the place where the underwater structure is installed is scoured. To prevent scour, but because the stone is obtained by collecting rock of a certain size, there is a problem of natural destruction, and there is a problem that the stone is lost in case of flood or typhoon. In recent years, as shown in FIG. The tetrapod 100 or the concrete block 101 shown in FIG. 2 or the scour prevention net 102 (also called gabion) shown in FIG. 3 are used to prevent scour.
즉, 테트라포드(100)는 다수개를 수중 구조물의 바닥에 쌓아 시공하는 것이고, 콘크리트블럭(101)은 다수개를 수중 구조물의 바닥에 배열 설치하되, 서로 맞물림으로 결합되도록 하는 것이며, 세굴방지망(102)은 일자형 독립망태로 되어 내부에 잡석을 채우고 이를 수중 구조물의 바닥에 배열 설치하는 것이다.That is, the tetrapod 100 is to build a plurality of stacked on the bottom of the underwater structure, concrete block 101 is to install a plurality of arranged on the bottom of the underwater structure, to be coupled to each other, scour prevention net 102 ) Is a flat, self-contained mesh that fills rubble inside and arranges it on the bottom of the underwater structure.
