Description

하천 보의 유인수로를 갖춘 어도{Fish ladder having a induced fishway of rivers barrage}Fish ladder having a induced fishway of rivers barrage}

본 발명은 하천 보의 유인수로를 갖춘 어도에 관한 것으로, 하천에 설치된 보 또는 수공구조물로 인하여 어류의 이동통로가 단절되면서 나타나는 수생태계의 서식처환경이 교란되는 현상을 방지하기 위한 어도를 설치할 때, 해당 어도와 병행하여 담수구역의 물이 방류되는 유인수로를 설치하여 집어효과는 높이면서 어도내의 유량을 안정되게 함으로서, 주 흐름을 형성하는 유인수에 의해 소상하는 어류가 용이하게 어도로 진입되도록 함과 아울러 통과율을 높일 수 있는 유인수로를 갖춘 어도에 관한 것이다.The present invention relates to a fishway equipped with a manned waterway of a river weir, and when installing a fishway to prevent the phenomenon in which the habitat environment of the aquatic ecosystem is disturbed when the moving passage of fish is cut off due to a weir or a water hole installed in a river, In parallel with the fishery, a manned waterway through which water from the freshwater area is discharged is installed to increase the fishing effect and stabilize the flow rate in the fishery, so that small fish can easily enter the fishery by the manned water forming the main flow In addition, it relates to a fishery equipped with a manned waterway that can increase the passing rate.

일반적으로 어도의 효율성은 어류가 어도의 입구로 들어오는 개체수의 비율로 표시되는 유인율과 어도 입구로 진입한 어류가 어도의 출구를 통과하였을 때의 개체수 비율로 표시되는 통과율로 표시되며, 종래의 어도는 별도의 유인수로가 없어서 어도에서 배출되는 용수를 유인수로 의존할 수밖에 없는 실정이었다.In general, the efficiency of a fishery is represented by an attraction rate represented by the ratio of the population of fish entering the entrance of the fishery and a passage rate represented by the ratio of the population when fish entering the fishery entrance pass through the exit of the fishery. As there was no separate manned waterway, it was inevitable to rely on the water discharged from the fishery as manned water.

수로형식의 버티컬슬롯식 어도는 용수량이 많아 방류되는 용수가 유인수 기능을 하여 별도의 유인수로를 필요로 하지 않으나, 하상계수가 큰 국내하천의 여건에서는 관개용수에 지장을 주기 때문에 적용하기 어려운 제약이 있어, 비교적 용수량이 적은 계단식 어도가 보편적으로 이용되고 있다.The waterway type vertical slot fishery does not require a separate manned waterway as the water discharged has a large amount of water, so it functions as a manned water. Therefore, terraced fisheries with relatively low water capacity are commonly used.

상기 용수량이 적은 계단식 어도는 갈수기 때 어도 이외로 물이 흐르지 않으므로 효율성이 적지만 어도로 흐르는 물이 유인수 기능을 발휘하여 집어효과를 기대할 수 있었으나, 하천의 유량이 연중 변화하는 특성으로 인하여 어류가 이동할 수 있는 기간이 극히 짧은 제약이 있었다.The terraced fishery with a small amount of water is less efficient because water does not flow to anything other than the fishery during the dry season. There was a very limited period of time available.

갈수량을 기준으로 설계된 계단식 어도는 유량이 증가하면 평수기에 어도 이외의 보 마루로 물이 흘러넘치게 되면서 어류가 어도 입구에 모이지 않게 되므로, 집어효과가 급격히 떨어지게 됨은 물로, 어도내의 유량도 증가하여 어류의 이동이 제한되면서 통과율이 급감하는 등, 유량변화에 대하여 적응하지 못하는 문제점과 홍수시 활발한 유사이동으로 어도 자체가 파손되거나 어도의 입·출구부가 유사퇴적으로 막히는 경우가 빈번히 발생하는 문제가 있었다.In the case of a terraced fishery designed based on the amount of dry water, when the flow rate increases, water overflows to the bottom of the fishery other than the fishery during the normal season, and fish do not gather at the entrance of the fishery. There was a problem of not being able to adapt to the change in flow rate, such as a rapid decrease in the passage rate as movement was restricted, and a problem that the fishway itself was damaged due to active sedimentary movement during floods or the entrance and exit of the fishery were frequently blocked with sedimentary deposits.

또한, 하상의 급격한 변화로 인한 최심선의 이동으로 갈수기 때 어도의 이용효율이 현저히 저하되는 경우도 다반사로 발생되어 유인효율 증대방안으로 “수리해석을 통한 어도의 최적의 위치선정(백경오. 2012.02.15. 학술기가, 물과 미래)에 대하여 발표한바 있으며, 최근에는 하상변화로 인한 최심선의 이동, 유량변화에 대한 부적응성 문제 및 집어효과의 문제점 등으로 이미 어도가 설치된 보에 어도확장 사업을 시행하는 추세이다.In addition, the case where the use efficiency of the fishway is noticeably lowered during the dry season due to the movement of the deepest line due to the rapid change of the river bed is a common occurrence, and as a method to increase the inducement efficiency, “optimal location selection of the fishery through hydraulic analysis (Baek Kyung-oh. 2012.02. 15. Academic period, water and future) has been presented, and recently, a project to expand a borehole with a fishway already installed has been implemented due to the movement of the deepest line due to riverbed change, the problem of inadequacy to the change in flow rate, and the problem of the fishing effect. is a trend

이러한 문제는 근원적으로 이동어류의 향류성과 주 흐름으로의 이동하는 어류의 일반적 특성을 인지하면서도 “취입보의 경우 관개용수 확보에 지장을 초래하지 않으면서 어도의 수심을 유지하며 유인수를 방류하여야 한다.”는 조건 때문에 유인수로의 개발이 지연되어 왔다.This problem is fundamentally aware of the countercurrent of migratory fish and the general characteristics of fish moving in the main flow, but “in the case of a weir, it is necessary to maintain the water depth of the fishery and release the attracting water without causing a hindrance to securing irrigation water.” The development of manned waterways has been delayed because of the conditions.

한편, 국내에서 현장시공이 어려운 아이스하버식 어도를 시공성이 높은 조립식 어도로 개발함과 아울러 표준형 어도로 선정한 바 있으며, 이에 따라 2014년 3월부터 어도 개보수사업 시행과 병행하여 모니터링을 실시하여 어류이동 효과 및 수산자원량 변화분석을 2016년 12월까지 실시하였다.On the other hand, the ice harbor type fishway, which is difficult to construct on site in Korea, was developed as a prefabricated fishery with high workability and was selected as a standard fishery. Analysis of effects and changes in fishery resources was conducted until December 2016.

“어도 개보수사업 모니터링 및 효과분석(해양수산부, 한국농어촌공사.2016) 조사연구”에서 어도 상·하류의 어류군집지수를 비교한 결과, 어도를 통한 하천 상·하류간 종적교류 증가로 군집의 안정도가 증가하여 종 다양도 및 풍부도가 증가하였고, 수산자원량 변동추이를 분석한 결과 개보수 이후 전체적으로 수산자원량이 증가한 것으로 나타났다.As a result of comparing the fish community index of the upper and lower streams of the fishery in the “Seasonal Improvement Project Monitoring and Effect Analysis (Ministry of Oceans and Fisheries, Korea Rural Community Corporation. 2016) Survey Study”, the stability of the community due to the increase in longitudinal exchange between the upper and lower streams through the fishery As a result of the increase in fishery resources, the diversity and abundance of species increased, and as a result of analyzing the change in fishery resources, it was found that the fishery resources increased overall after renovation.

다만, 최근 과학기술의 발달로 인하여 정량적 평가로 가장 많이 이용되는 PIT-tag(전자발신장치) 기법으로 어도 효율성을 실시한 결과, 유영력이 좋은 어종인 황어 및 연어는 57~100%의 통과율을 보이고, 기타 어류의 통과율은 32~40.0%로 나타났으나, 어도 입구에 진입한 어류 중 황어 및 영어는 11~25%, 기타 어류는 5.3~17.8%의 유인율을 보였다. However, as a result of conducting fishery efficiency with the PIT-tag (electronic transmitting device) technique, which is most commonly used for quantitative evaluation due to the recent development of science and technology, mince and salmon, which are fish species with good swimming ability, show a pass rate of 57 to 100%, The passing rate of other fish was 32~40.0%, but among the fish that entered the fishery entrance, yellowfish and English fish showed 11~25%, and other fish showed 5.3~17.8% of the attraction rate.

따라서 어도의 효율성을 유인율과 통과율의 곱으로 나타내면, 유영력이 좋은 어동의 경우 15% 이하이고 기타어류는 7% 미만으로써, 통과율이 높은 어도라도 유인수가 없으면 어도의 효율성을 개선할 수 없음을 확인 할 수 있었다.Therefore, when the efficiency of a fishery is expressed as the product of the attract rate and the pass rate, it is less than 15% for fish with good swimming ability and less than 7% for other fish, indicating that even a fish with a high pass rate cannot improve the efficiency of the fishery without attractants. was able to confirm

본 발명은 위와같은 종래의 어도에서 유량변화에 대한 부적응성과 집어효율의 저하로 인한 문제점을 감안하여 발명한 것으로, 그 목적은 담수구역으로부터 취수 또는 월류되는 물을 어도와 병행 설치한 유인수로를 통해 어도 입구의 하류로 방류함에 있어 관개용수의 공급에 지장을 주지 않으면서 하천 유량변화에도 어도내의 물 흐름을 안정화시켜 어류 이동을 쉽게하여 통과율을 향상하고, 어도 입구에 어류가 모이는 집어효과와 어류가 어도입구로 진입하도록 유도하여 유인율을 높임으로써 어도의 효율성을 향상시킬 수 있는 하천보의 유인수로를 갖춘 어도를 제공하는 것이다.The present invention was invented in view of the problems caused by the inadequacy of flow rate change and the decrease in fishing efficiency in the conventional fish passage as described above. In discharging to the downstream of the fish entrance, it stabilizes the water flow in the fish passage even when the flow rate of the river changes without disturbing the supply of irrigation water, thereby improving the passage rate by facilitating the movement of fish, and the effect of fish gathering at the fish entrance It is to provide a fishway equipped with a manned channel of a river weir that can improve the efficiency of the fishery by inducing entry into the fishery entrance and increasing the attracting rate.

이러한 목적을 달성하기 위하여 본 발명은, 보의 구조 및 다양한 현장여건에 따라 적어도 하나 이상 설치되는 어도에 인접하여 유인수로를 병행설치 가능하도록 발명하였다.In order to achieve this object, the present invention was invented to enable parallel installation of manned waterways adjacent to at least one fishway installed according to the structure of the beam and various field conditions.

담수구역의 유인수로 입구에 자동화시스템의 유인수문을 구비하여, 변화하는 하천유량에 따라 어도의 수심을 일정하게 유지하면서 유인수를 방류하여 어도내의 어류가 쉽게 이동할 수 있는 조건을 확보하면서 어류의 집어효과를 향상하는 것이다.An automatic system of manned water gates is provided at the entrance of the manned waterway in the freshwater area, keeping the water depth of the fishery constant according to the changing flow rate of the river and releasing the manned water to secure conditions for the fish in the fishery to move easily, and fish catch effect is to improve

가동보에서는, 상기 자동화시스템의 유인수문을 가동 보와 알고리즘이 연계된 설치로 하천의 유량변화에 따라 가동 보가 단계별 개방이 조절되고 이에 대응하여 유인수문은 어도의 수위를 유지하면서 유인수를 방류하는 방법이다.In the movable weir, the movable sluice gate of the automation system is installed in conjunction with the movable weir and the algorithm, so that the opening of the movable weir is adjusted in stages according to the change in the flow rate of the river. to be.

유인수가 방류되는 유인수로에는 이동어류가 효과적으로 어도에 진입할 수 있게, 유인수로와 병행 설치하여, 유인수로의 방류구를 어도의 입구보다 길게 설치하여 하류로부터 유인수를 따라 거슬러 소상하는 어류가 주 흐름의 가장자리로 이동하는 과정에서 자연스럽게 어도로 진입하게 유도하고, 콘크리트 보의 어도 출구부에는 홍수 시 상류에서 떠내려 오는 석력이 어도 안으로 들어가는 것을 방지하고, 어도 출구에서 나와 담수구역으로 진입하여 상류로 이동하여야 하는 어류가 유인수로에 빠져 하류로 떠내려가는 것을 방지하는 석력유입방지벽을 구비하며, 가동 보에서는 어도의 출구로 나오는 어류가 유인수로에 빠져 하류로 떠내려가는 것을 방지하기 위하여 어류진입 방지벽이 구비된 구성을 특징으로 한다.The manned waterway where the attracting water is discharged is installed in parallel with the manned waterway so that the migratory fish can enter the fishery effectively, and the discharge port of the manned waterway is installed longer than the entrance of the fishery so that the fish that migrate from the downstream along the baited water can enter the fishery of the main flow. In the process of moving to the edge, it is naturally induced to enter the fishway, and at the fishway exit of the concrete beam, stone force from the upstream in case of flooding is prevented from entering the fishway, and it is necessary to move upstream after entering the freshwater area from the fishway exit. A stone power inflow prevention wall is provided to prevent fish from falling into the manned waterway and drifting downstream, and in the movable weir, a fish entry prevention wall is provided to prevent fish coming out of the fishway from falling into the manned waterway and being washed downstream. Characterized by composition.

이와 같은 본 발명의 유인수로는 담수구역에서 취수하여 방류함으로서 계단식 어도의 유량변화에 대한 부적응성을 해소하여 어도를 소상하는 어류의 통과율을 향상시키고, 방류된 유인수는 어도입구의 하류부로 확산됨에 따라 집어효과를 향상하고, 유인수로의 방류구를 어도의 입구보다 길게 설치하여 유인수를 따라 이동하는 어류가 자연스럽게 어도로 진입하는 구조로 설치되어 어류의 유인율을 향상할 수 있는 효과가 있다.As such, the attractant water of the present invention takes in water from the freshwater area and discharges it, thereby solving the inadequacy of the terraced fishery to the change in flow rate, improving the passage of fish that damage the fishery, and the discharged attractant water spreads to the downstream part of the fishery entrance There is an effect of improving the attracting rate of fish by improving the fishing effect and installing a structure in which the fish moving along the attracting water naturally enters the fishery by installing the outlet of the attracting water longer than the entrance of the fishery.

또한, 홍수 시 떠내려 오는 석력이 어도로 들어가 격벽을 훼손하거나 어도의 입구에 석력이 퇴적되는 것을 방지하는 석력유입방지벽을 설치하여 유인수로를 통하여 배출함으로써, 어도의 내구성 향상과 관리가 용이하여 유지관리비용이 저렴한 경제적인 장점과 하상의 변화로 인한 최심선이 이동하지 않는 장점이 있다.In addition, by installing a stone power inflow prevention wall to prevent stone power from entering the fishery and damaging the bulkhead or depositing stone power at the entrance of the fishery and discharging it through the manned waterway, the durability of the fishery is improved and management is easy to maintain It has the economic advantage of low management cost and the advantage that the deepest line does not move due to changes in the river bed.

또한 유인수문과 그 유인수문을 갖춘 유인수로를 가동 보에 설치하여 각각 또는 상호 연계된 자동화시스템에 의해 동작을 제어함으로써, 가동보가 개방되는 초기단계에서는 유인수로에서 방류되는 유량이 많아 주 흐름을 유지할 수 있어, 집어효과와 더불어 어류가 어도를 이동할 수 있는 기간을 향상시키고, 홍수 때는 가동 보의 개방을 점진적으로 이루어지도록 하여 급류로 인한 하류지역에 발생될 수 있은 피해를 방지할 수 있다.In addition, by installing manned water gates and manned waterways equipped with the manned water gates on movable weirs and controlling their operation by each or mutually linked automation system, in the initial stage when the movable weirs are opened, the flow rate discharged from the manned waterways is large, so that the main flow can be maintained. As a result, it is possible to improve the period during which fish can move through the fish passage along with the catch effect, and to prevent damage that may occur in the downstream area due to rapid current by gradually opening the movable weir in case of flood.

이하, 본 발명의 하천 보의 유인수로를 갖춘 어도를 첨부 도면을 참조하여 설명하면 다음과 같다.Hereinafter, the fishway equipped with the manned channel of the river weir of the present invention will be described with reference to the accompanying drawings.

도 1 내지 도 3은 본 발명의 유인수로 갖춘 어도가 콘크리트 고정보 및 가동보에 설치된 자동화시스템이 적용된 유인수문의 설치상태를 나타낸 사시도로서, 본 발명은 관개용수를 확보하기 우한 하천 보(100)에 어류의 생태이동통로인 어도(120)를 설치할 때 그 어도의 입구가 위치하는 하류로 물을 방류하는 유인수로(300)를 병행 설치하여 하류로부터 거슬러 올라오는 어류를 어도 입구로 유인 및 통과되게 하면서 유량증가에 의한 변화에 적응할 수 있도록 한 것이다.1 to 3 are perspective views showing the installation state of the manned water gate to which the automation system installed on the concrete fixed weir and the movable weir is applied to the fishway equipped with the manned water of the present invention. When installing the fish passageway 120, which is an ecological passageway for fish, a manned waterway 300 that discharges water to the downstream where the entrance of the fish passage is located is installed in parallel to attract and pass the fish coming up from the downstream to the entrance of the fish passage It is designed to adapt to the changes caused by the increase in flow rate.

상기 어도(120)는 물이 흐르는 방향으로 거슬러 이동하려는 어류의 유영특성과 주 흐름을 이탈하지 않으면서 가장자리의 유속이 느린 부분을 이용하여 이동하는 생태적 습성을 이용하기 위해 하나 이상 설치하되 복수로 설치되는 어도인 경우 유인수로(300)를 중앙으로 그 양측에 각각 어도(120)를 인접되게 병행 설치하고, 단수의 어도인 경우에도 유인수로(300)에 인접되게 병행설치하는 것이 바람직하다.The fish 120 is one or more installed in order to take advantage of the swimming characteristics of fish trying to move against the flowing direction and the ecological habit of moving using the slow-flowing part of the edge without departing from the main flow, but installed in plurality In the case of a canal, it is preferable to install the canalway 300 in parallel on both sides of the canalway 300 adjacent to each other, and even in the case of a single fishery, it is preferable to install it in parallel adjacent to the canalway 300.

상기 유인수로(300)에서 빠른 유속으로 확산되는 유인수가 어도(120)의 입구를 막지 않도록 어도의 입구보다 길게 설치함으로써, 주 흐름이 형성된 유인수의 가장자리를 따라 소상하는 어류가 어도의 입구에 자연스럽게 진입되게 하여 집어를 효율적으로 하게 된 것이다.By installing the attracting water spreading at a high flow rate in the attracting water channel 300 longer than the entrance of the fishery 120 so as not to block the entrance of the fishery, small fish naturally enter the entrance of the fishery along the edge of the attracting water where the main flow is formed By doing so, it became efficient to pick up.
