Description

세굴방지용 블럭{Scour prevention block}Scour prevention block

본 발명은 세굴방지용 블럭에 관한 것으로서, 더욱 상세하게는 동일한 형상으로 구비하여 강바닥의 사방으로 인접하게 배치하여 결합하고 상하방향으로 적층하여 견고하게 결합할 수 있으므로 강바닥의 유지 및 강에 설치하는 구조물을 보호하고 강바닥의 토사의 세굴을 방지하며, 세굴방지용 블럭의 중심부에 어패류 서식홀을 형성하고, 세굴방지용 블럭의 상면에 수초 자연발아용 식생매트를 설치하여 수초가 생착할 수 있게 한 세굴방지용 블럭에 관한 것이다.The present invention relates to a block for preventing scouring, and more particularly, it is provided in the same shape, arranged adjacent to each other in all directions of the river bed, and can be firmly bonded by stacking in the vertical direction. It protects and prevents scouring of the soil of the river bed, forms a hole for fish and shellfish in the center of the scour prevention block, and installs a vegetation mat for natural germination of aquatic plants on the upper surface of the block for prevention of scouring. About.

유속이 빠른 하천의 강바닥, 구조물 주위, 하천 변의 지반이 약한 부분 등에서 물의 흐름에 의해 토양이 유실된다.Soil is lost by the flow of water in riverbeds of rivers with high flow rates, around structures, and areas with weak ground along the river side.

세굴은 수류의 국부적인 집중으로 경계면이 깍이는 현상을 의미하며, 수중에 구조물을 만들면 그에 접하는 토사가 물의 흐름에 의해 세굴되어 구조물의 내구성, 안정성 등에 영향을 미치고 환경 문제를 유발하게 된다.Scouring refers to a phenomenon in which the boundary surface is sharpened due to the local concentration of water current, and when a structure is made underwater, the soil in contact with it is scoured by the flow of water, affecting the durability and stability of the structure, and causing environmental problems.

종래의 세굴방지용 블럭은 강바닥에 평면적으로 설치되어 블럭과 블럭의 측면이 서로 결속되지 못하고 단순히 직선 면과 면이 접한 상태로 시공되어 하천의 유속이 심한 경우 단위 블럭이 유실되고 토사의 세굴을 막지 못하는 문제점이 있었다.Conventional scour-preventing blocks are installed flat on the river bed so that the sides of the block and the blocks cannot be bonded together, and they are simply constructed in a state where the straight surface and the surface are in contact.If the flow velocity of the river is severe, the unit block is lost and the scouring of the soil cannot be prevented. There was a problem.

또한, 종래의 세굴방지용 블럭은 하천의 유속을 상쇄시키는 구조가 없었고 블럭 상호간의 결합을 높여주는 구조가 없는 문제점이 있었다.In addition, there is a problem in that the conventional scour prevention block does not have a structure that cancels the flow velocity of the river and does not have a structure that increases the bonding between the blocks.

또한, 종래의 세굴방지용 블럭은 어패류의 서식공간이 마련되지 않아서 친환경적인 기능을 하지 못하는 문제점이 있었다.In addition, there is a problem in that the conventional scour prevention block does not provide an eco-friendly function because a habitat for fish and shellfish is not provided.

또한, 종래의 세굴방지용 블럭은 수초가 자라는 환경이 마련되지 않아서 블럭 사이에서 수초가 자연발아하지 못하고 자라지도 못하는 문제점이 있었다.In addition, there is a problem in that the conventional scouring prevention block does not have an environment in which the plants grow, so that the plants cannot spontaneously germinate and grow between blocks.

본 발명의 기술이 적용되는 세굴방지용 블럭은 동일한 형상으로 구비하여 강바닥의 사방으로 인접하게 배치하여 결합하고 상하방향으로도 적층할 수 있다. 그리하여, 본 발명의 세굴방지용 블럭은 강바닥의 유지 및 수중에 설치하는 구조물을 보호하고 강바닥의 토사의 세굴을 방지하는 역할을 하게 된다.The block for preventing scouring to which the technology of the present invention is applied may be provided in the same shape, arranged adjacent to each other in all directions of the river bed, combined, and stacked in the vertical direction. Thus, the scouring prevention block of the present invention serves to maintain the river bed and protect the structure installed in the water, and to prevent the scouring of the soil in the river bed.

첨부도면 도 1 내지 도 10에서 도시한 바와 같이, 본 발명에 따른 세굴방지용 블럭(이하, '블럭'이라 함)은 본체(1), 상면(100), 하면(200), 측면(300), 코너 빗면부(400), 유속밀림 방지용 돌기(210), 수중 폭기용 돌기(110), 어패류 서식홀(500), 어패류 이동로(310), 어패류 유입통로(510), 아이볼트(410), 식생매트 삽입홈(120), 수초 자연발아용 식생매트(121)를 포함하여 이루어진다.As shown in the accompanying drawings Figures 1 to 10, the scour prevention block (hereinafter referred to as'block') according to the present invention is the main body 1, the upper surface 100, the lower surface 200, the side surface 300, Corner bevel part 400, protrusion 210 for preventing flow velocity, protrusion 110 for underwater aeration, fish and shellfish breeding hole 500, fish and shellfish movement path 310, fish and shellfish inflow passage 510, eye bolt 410, It comprises a vegetation mat insertion groove 120, a vegetation mat 121 for spontaneous germination of aquatic plants.

본체(1)는 유속이 빠른 하천의 교각 주위에 블럭을 설치할 경우, 빠른 유속에서도 견고하게 지탱하고, 강바닥으로부터 부상(浮上)을 방지하기 위해 충분한 중량을 갖도록 콘크리트 재질로 이루어지는 것이 바람직하다.When a block is installed around the pier of a river with a high flow rate, the main body 1 is preferably made of a concrete material so that it is firmly supported at a fast flow rate and has sufficient weight to prevent injury from the river bed.

본체(1)는 30 MPa(Mega Pascal) 이상의 고강도 콘크리트로 팔각형 형상으로 제작하여 충격에 의해 부서지지 않는 내구성을 가진다.The main body 1 is made of high-strength concrete of 30 MPa (Mega Pascal) or more in an octagonal shape and has durability that is not broken by impact.

본체(1)의 상면(100) 및 하면(200)은 평평하게 형성한다. 즉, 본체(1) 상면(100)은 물의 흐름을 원활하게 하기 위해 평평하게 형성한다. 본체(1)의 하면(200)도 강바닥에 놓기 위해 평평하게 형성한다.The upper surface 100 and the lower surface 200 of the main body 1 are formed flat. That is, the upper surface 100 of the main body 1 is formed flat to facilitate the flow of water. The lower surface 200 of the main body 1 is also formed flat to place it on the river bed.

본체(1)의 측면(300)은 수직면으로 형성한다.The side surface 300 of the main body 1 is formed in a vertical surface.

코너 빗면부(400)는 본체(1)의 측면(300)의 4개의 코너쪽에 모깎기를 한 것처럼 서로 인접하는 양쪽 측면(300)을 연결하는 비스듬한 수직면으로 형성한다.The corner beveled portion 400 is formed as an oblique vertical surface connecting both side surfaces 300 adjacent to each other, as if the four corners of the side surface 300 of the main body 1 were filled in.

유속밀림 방지용 돌기(210)는 본체(1)의 하면(200)의 4개의 코너쪽에 하방으로 돌출형성하여 유속에 의해 본체(1)가 밀리는 것을 방지한다. 즉, 유속밀림 방지용 돌기(210)는 본체(1)의 자중에 의해 강바닥에 충분히 박혀 강바닥으로부터 부상(浮上)되는 것을 방지한다.The protrusion 210 for preventing the flow velocity is protruded downward at the four corners of the lower surface 200 of the main body 1 to prevent the main body 1 from being pushed by the flow velocity. That is, the protrusion 210 for preventing the flow velocity is sufficiently embedded in the river bed by its own weight of the main body 1 to prevent it from being injured from the river bed.

수중 폭기용 돌기(110)는 본체(1)의 상면(100)의 4개의 코너쪽에 유속밀림 방지용 돌기(210)와 상하로 대칭되는 형상을 가지도록 돌출형성하여 유속이 여러방향으로 흩어져 느려지게 하고 기포도 발생시켜서 수생식물 및 어패류의 서식에 도움을 준다.The protrusions for underwater aeration 110 protrude to have a shape symmetrical up and down with the protrusions 210 for preventing the flow velocity in the four corners of the upper surface 100 of the main body 1, so that the flow velocity is scattered in various directions and slows down. It also generates air bubbles and helps in the habitat of aquatic plants and fish and shellfish.

어패류 서식홀(500)은 본체(1)의 중심부를 상하로 관통하도록 큰 구멍으로 형성하여 유속에 따른 외압을 상쇄시키고 블럭 상호간의 결합력을 높이며 어패류의 서식공간을 마련해준다.The fish and shellfish breeding hole 500 is formed as a large hole so as to penetrate the center of the main body 1 vertically to offset external pressure according to the flow velocity, increase the bonding force between blocks, and provide a habitat for fish and shellfish.

어패류 이동로(310)는 본체(1)의 각 측면(300)에 측면(300)을 따라 소정의 폭과 깊이를 가지는 홈으로 형성하여 어패류의 이동 및 유입을 유도하게 된다.The fish and shellfish movement path 310 is formed in a groove having a predetermined width and depth along the side surface 300 on each side surface 300 of the main body 1 to induce movement and inflow of fish and shellfish.
