본 발명은 소하천의 교각기초에 관한 것으로, 더욱 상세하게는 소하천 교각기초에 하천수 저장공간을 갖는 어류보호시설을 마련하여 상기 어류보호시설내에서 물고기와 같은 수중생명체가 안전하게 서식할 수 있도록 개선된 어류보호시설이 구비된 소하천의 교각기초에 관한 것이다.The present invention relates to a pier foundation of a small river, and more particularly, to provide a fish protection facility having a river water storage space in a small river pier foundation to improve the safety of the aquatic life such as fish in the fish protection facility It relates to the foundation of bridges in small rivers with shelter.

교량(bridge; 또는 다리)은 하천, 호소(湖沼), 해협, 만(灣), 운하, 저지 또는 다른 교통로나 구축물(構築物) 위를 건너갈 수 있도록 만든 고가 구조물의 하나이다.A bridge is a type of expensive structure that allows you to cross over rivers, lakes, straits, bays, canals, lowlands, or other traffic routes or structures.

교량의 역할은 거의 같아서 다리가 받쳐주는 통로와 시설의 기능을 안전하게 유지하는 일이며, 그러기 위해서는 충분한 강도와 내구성(耐久性)을 갖추어야 한다.The role of the bridge is almost the same, and the function of the bridge and the facilities supported by the bridge is to be kept safe. To do so, it must have sufficient strength and durability.

또한, 교량은 통상적으로 상,하부구조로 나뉘어지는바, 상부구조라 함은 차량하중을 직접 지지하는 부분으로 상판 바닥틀과 주형으로 구성되어 있고, 하부구조라 함은 상부구조로부터의 하중을 지반으로 전달하는 역할을 하는 부분으로 교대, 교각 및 기초(말뚝 기초,우물통 기초 등)로 구성되어 있다.In addition, the bridge is generally divided into upper and lower structures, the upper structure is a portion that directly supports the vehicle load and consists of a top plate frame and a mold, and the lower structure transfers the load from the upper structure to the ground It is composed of shifts, piers and foundations (pile foundations, well foundations, etc.).

이와 같이 상,하부구조로 이루어진 교량 중 해상에 가설되는 교량은 그 시공이 매우 어려울 뿐만 아니라 시공 후, 유지관리하는데 있어서도 매우 어려운 문제가 있었다.As such, the bridges constructed on the sea among the bridges having upper and lower structures are not only difficult to construct, but also have very difficult problems in maintenance after construction.

그래서 종래에도 수중 구조물의 주변에 다수개의 테트라포트, 매트형의 블록 또는 돌망태 등을 설치하여 세굴 현상이 방지되도록 하고 있으나, 상기 테트라포트의 경우에는 해변의 방파제용으로는 어느 정도 적합하나 유속이 느린 하천에서는 부적합하며, 상기 매트형의 블록은 세굴 현상이 심하지 않은 곳에서는 시공비의 상승으로 비경제적이고, 상기 돌망태의 경우에는 독립형으로 되어 홍수 시에는 유실되거나 망태의 형태가 변형됨으로써 그 효과가 저하되는 등의 문제점들이 있다.Therefore, conventionally, a plurality of tetraports, mat-shaped blocks, or gabions are installed around the underwater structure to prevent scour. However, the tetraports are somewhat suitable for beach breakwater, but have a slow flow rate. It is unsuitable in rivers, and the mat-shaped block is uneconomical due to an increase in construction cost in places where scour is not severe, and in the case of the gabion, it becomes independent and is lost during flooding or the shape of the mesh is deformed, thereby degrading its effect. There are problems.

또한, 수심이 깊을수록 하천바닥의 유속이 빨라져, 하천바닥에 매입되어 시공되어진 수중구조물을 둘러싼 하천바닥의 세굴 현상이 더욱 심화되며, 이렇게 빠른 유속으로 인하여 하천에 서식하는 수생생물들이 구조물의 주위에 서식하기에는 부적당하다는 문제점이 있다.In addition, the deeper the depth, the faster the flow rate of the riverbed, the deeper the scour phenomenon of the riverbed surrounding the submerged structure is buried in the riverbed, the rapid flow rate of aquatic life in the river The problem is that it is not suitable for habitation.

그리고 가믐으로 인해 하천수가 모두 고갈되는 경우 하천에 서식하는 물고기 와 같은 어류를 포함하여 수생식물이 생존할 수 없어 생태계 파괴시 이를 복원하는데 많은 시간과 노력이 요구되기도 하였다.In addition, when all of the river water is depleted due to poverty, aquatic plants, including fish such as fish in the river, cannot survive, requiring much time and effort to restore the ecosystem.

상기한 바와 같은 종래의 문제점을 감안 해소하고자 발명된 것으로, 본 발명의 목적은 소하천의 교각기초에 햇볕에 직접 노출되지 않는 별도의 하천수 저수공간을 구비하여 상기 저수공간에서 물고기와 같은 어류들이 안전하게 생존할 수 있는 서식환경을 제공하여 생태계 보호에 크게 기여할 수 있도록 개선된 어류보호시설이 구비된 소하천 교각기초를 제공하고자 한다.In order to solve the conventional problems as described above, the object of the present invention is to provide a separate river water reservoir that is not directly exposed to the sun in the bridge piers of small rivers, fish such as fish survive safely in the reservoir It aims to provide a small river pier foundation with improved fish protection facilities to provide a habitat environment that can make a significant contribution to ecosystem protection.

도 5에 나타낸 바와 같이 상기 고정링(65)은 고무와 같은 신축성 있는 소재로 형성되어 양쪽 끝단부에 서로 상반되는 오른나사조립부(651)와 왼나사조립 부(652)가 각각 형성되어 양쪽 나사조립부(651)(652)는 양단부에 이들과 나사 결합되는 암나사가 형성된 체결너트(66)와 나사 결합되게 조립하여 상기 체결너트(66)를 정,역방향으로 회전시키면서 양쪽 나사조립부(651)(652)를 상호 분해 조립하는 방법으로 몸체(61) 또는 날개부재(64)를 조립하거나 분리하도록 되어 있다.As shown in FIG. 5, the fixing ring 65 is formed of an elastic material such as rubber, and the right screw assembly 651 and the left screw assembly 652 which are opposite to each other at both ends are formed, respectively, and thus both screw assembly is performed. The parts 651 and 652 are assembled to be screwed together with a fastening nut 66 formed with female threads screwed to them at both ends thereof, while rotating the fastening nut 66 in a forward and reverse direction, with both screw assembly parts 651 ( It is to assemble or separate the body 61 or the wing member 64 by a method of mutually disassembling the 652.

이와 같이 구성된 본 발명은 도 1과 도 5에 나타낸 바와 같이 교량(10)이 구비된 교각기초(30)를 하천 바닥(20)에 시공함에 있어 상기 교각기초(30)의 내측에 어류보호시설 즉, 하천수를 수용 및 저장할 수 있는 공동부(32)와 유속을 저감시킬 수 있는 유속저감대(50) 및 물고기들과 같은 수중생명체가 공동부로 자유롭게 드나들 수 있는 가이드부재(60)를 병설하여 상기 공동부(32)내에서 물고기와 같은 수중생명체가 안전하게 서식할 수 있도록 유도하고 있는 것이다.1 and 5, the present invention configured as described above has a fish protection facility inside the bridge foundation 30 when constructing the bridge foundation 30 having the bridge 10 on the stream bottom 20 as shown in FIGS. In addition, the cavity 32 for accommodating and storing the river water, and the flow rate reduction zone 50 for reducing the flow rate and the guide member 60 that can freely enter the cavity portion of the underwater life, such as fish In the cavity 32 is to induce aquatic life, such as fish to inhabit safely.

따라서 하천의 교각기초(30)내에 설치되는 공동부(32)에서 물고기들은 안전하게 부화 및 산란도 가능한 것이다.Therefore, in the cavity 32 installed in the bridge foundation 30 of the river, the fish can safely hatch and spawn.

한편, 하천수가 모두 고갈되는 가믐시에도 교각기초(30)의 공동부(32)내에는 하천수가 남아있게 되므로 다시 하천수가 하천에 유입될 때까지 물고기들이 고사되는 일이 없이 안전하게 서식할 수 있는 것이며, 교각기초(30)의 공동부(32)에 남게되는 하천수는 햇볕으로부터 차단된 상태이므로 쉽게 고갈되지 않는다는 이점이 있다.On the other hand, even when all the river water is exhausted, since the river water remains in the cavity 32 of the bridge foundation 30, the fish can safely inhabit without being killed until the river water flows back into the river. , The river water remaining in the cavity 32 of the bridge foundation 30 has the advantage that it is not easily depleted because it is blocked from the sun.

그리고 하천의 교각기초(30) 주변을 지나는 하천수는 교각기초(30)의 배면부에 설치되는 유속저감대(50)의 곡면가이드(53)가 물의 흐름을 완만하게 유도하게 되고, 이이와 병설되는 가이드부재(60)에 조립되는 다수의 날개부재(64)도 하천수 와 접촉하면서 자유롭게 움직이면서 물의 유속을 저감시킬 수 있는 이점이 있게된다.And the stream water passing around the pier foundation 30 of the river guides the surface guide 53 of the flow rate reduction zone 50 installed in the back portion of the pier foundation 30 to gently induce the flow of water, and the parallel guide A plurality of wing members 64 assembled to the member 60 also has the advantage of reducing the flow rate of the water while moving freely in contact with the river water.

이상에서 설명한 바와 같이 본 발명에 의하면, 하천 바닥에 시공되는 교각기초(30)의 내측에 수중생명체가 안전하게 서식할 수 있는 공동부(32)를 설치하여 비교적 작은 물고기들도 안전하게 서식할 수 있어 수중생명체 보호에 크게 기여할 수 있는 이점이 있다.As described above, according to the present invention, by installing the cavity 32 which can safely inhabit underwater life inside the pier foundation 30 to be installed on the bottom of the river, relatively small fish can be safely inhabited. There is an advantage that can greatly contribute to the protection of life.

또한, 교각기초(30)의 배면부에 설치되는 유속저감대(50)와 가이드부재(60)는 하천수의 흐름을 저감시키게 되어 하천 바닥이 유실되는 세굴방지 효과도 겸할 수 있는 것이다.In addition, the flow rate reduction zone 50 and the guide member 60 installed on the rear portion of the bridge foundation 30 can reduce the flow of the river water can also serve as a scour prevention effect that the bottom of the river is lost.

그리고 홍수 또는 장마로 인해 하천의 유속이 급격하게 빨라지더라도 교각기초(30)에 시공되는 공동부(32)는 수중생명체가 안전하게 대피할 수 있는 피난처의 역활을 수행하게 되어 수중생태계를 보호하는 하는데 크게 일조하는 등의 이점이 있는 매우 유용한 발명인 것이다.And even if the flow velocity of the river rapidly increases due to flooding or rainy season, the cavity 32 installed in the foundation of the pier 30 serves as a shelter where the aquatic life can be safely evacuated, thereby greatly protecting the aquatic ecosystem. It is a very useful invention which has the advantage of being helpful.

이상에서는 본 발명을 특정의 바람직한 실시 예를 들어 도시하고 설명하였으나, 본 발명은 상기한 실시 예에 한정되지 아니하며 본 발명의 정신을 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진자에 의해 다양한 변경과 수정이 가능할 것이다.The present invention has been shown and described with reference to certain preferred embodiments, but the present invention is not limited to the above-described embodiments and has ordinary skill in the art to which the present invention pertains without departing from the spirit of the present invention. Various changes and modifications may be made by the user.
