하천 저면의 어소블록{A FISHING PLACE BLOCK AT BOTTOM OF THE RIVER} A FISHING PLACE BLOCK AT BOTTOM OF THE RIVER}

본 발명은 하천 저면의 어소블록에 관한 것으로서, 보다 구체적으로는 수중 생물의 식생을 위해 설치가 간단하고 중량이 가벼운 한편, 수중에서도 견고히 고정될 수 있는 구조를 갖는 하천 저면의 어소블록에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assoblock on a bottom of a river, and more particularly to an assoblock on a bottom of a river having a structure that is simple to install and light in weight for the vegetation of aquatic organisms, and that can be firmly fixed in water.

일반적으로 어소블록이라 함은 하천에서 서식하는 물고기들의 산란처 및 피난처와 같은 수중 생태계를 보호하고자 하기 위한 것으로, 기존의 이러한 어소블록은 주로 콘크리트로 제작됨에 따라 수생식물이 식생하기 어렵거나 그 하중이 무거워 운반, 제거, 유지보수 등이 어려운 문제점이 있으며, 하천 유속에도 변화를 줄 수 있어 빠른 유속이 일어나는 지점에서는 어류가 서식하거나 수생식물이 자라기 위한 조건이 성립되지 않아 본연의 목적에 부합하지 않는 문제점이 있다. 또한 유속이 느린 곳에서는 침전물이 지속적으로 쌓여 하천 오염을 악화시키게 되는 문제점이 있다.In general, an assoblock is intended to protect aquatic ecosystems, such as spawning and shelter of fish inhabiting rivers. Existing sosoblocks are mainly made of concrete, making aquatic plants difficult to grow or heavy. Transport, removal, and maintenance are difficult problems, and the flow rate of the stream can be changed, so the conditions for fish inhabiting or growing aquatic plants are not established at the point where rapid flow rates occur, which does not meet the original purpose. have. In addition, there is a problem that in the place where the flow rate is slow, sediment is continuously accumulated to worsen the pollution of the river.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위해 안출된 것으로서, 하천의 자연스러운 유속을 최대한 보장하면서 수생식물과 어류의 서식처를 제공하여 수중 생태계를 보호할 수 있는 한편, 무게가 가벼우면서도 하천에 견고히 고정가능한 구조를 갖는 하천 저면의 어소블록을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, while providing a habitat for aquatic plants and fish while ensuring the natural flow rate of the river to the maximum, while protecting the aquatic ecosystem, while being light in weight and firmly in the river It is an object of the present invention to provide an assoblock at the bottom of a river having a fixed structure.

상기 목적을 달성하기 위하여, 본 발명은, 복수개의 사각막대로 이루어지고, 그 사각막대 각각에 길이방향을 따라 수직하게 복수개의 체결홀이 형성된 받침프레임과; 상기 받침프레임의 사각막대 끝단과 일측이 힌지결합되는 회동막대와, 상기 회동막대 타측과 힌지결합되고 끝단에 복수개의 핀홀이 형성된 고정패널이 설치되는 회동부로 이루어져 수중 경사면에 핀고정되는 경사고정부와; 상기 체결홀과 나선결합되어 사각막대 외측으로 돌출되고 하부 내측에 나선홀이 형성된 제1 원통부와, 상기 제1 원통부 상측으로 연장되고 상기 나선홀과 결합가능한 제2 원통부와, 상기 제1 원통부 하부로부터 수평하게 대향되어 연장되는 손잡이로 이루어져 상기 받침프레임이 입체적으로 배치되도록 하는 체결돌부와; 상기 체결돌부의 제1 원통부가 삽입가능한 복수개의 관통공이 형성되고 수평방향으로 배치되는 복수개의 상기 사각막대를 상호간에 고정시키도록 배치되는 타공판과, 상기 제1 원통부에 삽입가능한 복수개의 절취홀이 형성되고 상기 타공판에 적층되는 식생부직포로 이루어 지며, 상기 제1 원통부에 체결되는 결합너트에 의해 상기 사각막대에 고정되는 식생부;로 이루어지되, 상하로 위치되는 상기 사각막대 중 최하부에 배치되는 사각막대 양측 길이방향을 따라서는 수중저면에 상기 받침프레임을 핀고정하기 위해 복수개의 고정홀이 형성된 연장패널이 더 설치되는 것을 특징으로 한다.In order to achieve the above object, the present invention, the support frame made of a plurality of rectangular bars, the plurality of fastening holes are formed vertically along the longitudinal direction in each of the rectangular bars; An inclined fixing part pinned to an inclined surface of the support frame consists of a rotating rod hinged to one end and one side of the square bar of the supporting frame, and a rotating part installed to be hinged with the other side of the rotating rod and formed with a plurality of pinholes at the ends. Wow; A first cylindrical part spirally coupled to the fastening hole and protruding to an outer side of the rectangular bar, and having a spiral hole formed at a lower inner side thereof; a second cylindrical part extending upward from the first cylindrical part and coupled to the spiral hole; A fastening protrusion configured to include a handle extending horizontally from a lower portion of the cylindrical portion so that the support frame is three-dimensionally disposed; A perforated plate is formed to fix the plurality of rectangular bars arranged in the horizontal direction and a plurality of through holes into which the first cylindrical portion of the fastening protrusion is inserted, and a plurality of cutting holes insertable into the first cylindrical portion. A vegetation nonwoven fabric formed on the perforated plate and laminated to the perforated plate, the vegetation part being fixed to the square bar by a coupling nut fastened to the first cylindrical part; An extension panel having a plurality of fixing holes is further installed to pin the support frame to the underwater bottom along both longitudinal directions of the rectangular bar.

또한 수직방향을 따라 상하로 배치되는 상기 체결돌부 사이에는 하부 내측면이 상기 제2 원통부와 결합가능하고 상부 외측면이 상기 나선홀과 결합가능한 높이조절부가 더 설치되는 것을 특징으로 한다.In addition, between the fastening protrusions arranged vertically in the vertical direction, a lower inner surface is coupled to the second cylindrical portion and the upper outer surface is characterized in that the height adjusting portion is further coupled to the spiral hole.
