본 발명은 자연석을 이용한 취수용 취입보의 설치공법, 보다 상세하게는 하천이나 강에서 일정량의 물을 담수되게 하여 갈수기 때에 필요로 하는 관계용수를 용수로로 도입하기 위해 설치되는 취입보를 자연석을 이용하여 시공함으로써 생태환경에 친화적이면서 시설물의 내구성을 향상시킬 수 있게한 자연석을 이용한 취수용 취입보의 설치공법에 관한 것이다.The present invention provides a construction method of the intake blower using natural stone, more specifically, using a natural stone to install a blower installed in order to introduce the relevant water required in the water flow to make a certain amount of water in the river or river It is related to the installation method of the intake blower using a natural stone that can be friendly to the ecological environment and improve the durability of the facility.
일반적으로, 계절에 따라 물의 흐름량이 현저하게 변화되는 하천이나 강에는 용수를 확보하기 위한 목적으로 강폭을 가로 지르는 이른바 취입보가 시공되어 있다.In general, a so-called blown beam that crosses the river width is constructed in rivers or rivers in which water flow rate changes significantly with the season to secure water.
도 1은 종래의 철근 콘크리트 공법으로 시공된 취입보의 일예를 나타낸 단면구성도로서, 하천의 폭 방향으로 위치하여 물막이 역할을 하는 구조물(1)을 철근 콘크리트로 시공하되 물이 채워지는 구조물(1)의 상부면(2)을 수압에 대응하도록 적정두께로 형성하고, 상기 상부면(2)에서 하류측으로 이어지는 부위에는 물이 넘칠 때 경사면을 따라 낙차되면서 물의 흐름을 완화되게 하는 물받이(3)가 형성되어 있다.1 is a cross-sectional view showing an example of a blown beam constructed by a conventional reinforced concrete method, the structure (1) to be placed in the width direction of the river to act as a water barrier (1) to be reinforced with reinforced concrete structure (1) The upper surface (2) of the to form a proper thickness to correspond to the water pressure, and in the portion leading from the upper surface (2) to the downstream side is formed drip tray (3) to relax the flow of water while falling along the slope when the water overflows It is.
상기 종래의 콘크리트 구조물로 된 취입보는 레미콘의 공급에 의해 시공을 하게 됨으로써 시공성이 우수하여 거의 모든 취입보에서 채택된 바 있으며, 현재에 있어서도 가장 보편적인 시공법으로 간주되고 있다.Blowing beams made of the above-mentioned concrete structures have been adopted by almost all blown beams because they are excellent in workability by being constructed by the supply of ready-mixed concrete, and are considered to be the most common construction methods even now.
예컨데, 취입보를 시공할 때 선행되어야 할 조사항목으로 하천의 상황, 이수 및 치수에 관한 조사, 지형 및 지질조사, 환경에 관한 조사, 공사와 시공조건 및 관리에 관한 조사 등이 규정화되어 있다.For example, the survey items that should be preceded when constructing blown beams are prescribed for river conditions, surveys on completion and dimensions, terrain and geological surveys, environmental surveys, construction and construction conditions, and management.
상기 조사항목에서 볼 때 종래의 철근 콘크리트로 시공된 취입보는 주변환경과 제대로 조화를 이루지 못하면서 경관을 저해하는 요인과, 생태계에도 좋지 않은 영항을 미치게 되는 점 등이 지적되고 있으나, 관계용수를 확보하기 위한 차원에서 환경부분에 대한 항목을 도외시할 수 밖에 없는 현실적인 어려움을 감수해야만 하였다.From the above survey items, it is pointed out that the blown beams constructed of conventional reinforced concrete have factors that hinder the landscape and have a bad effect on the ecosystem without being properly harmonized with the surrounding environment. For the sake of clarity, we had to face the practical difficulties of neglecting the items on the environmental part.
한편, 콘크리트 구조물로 된 종래의 취입보는 도 2에서와 같이 구조물(1)의 상부면(2)을 넘어 경사면으로 이어진 물받이(3)의 하류로 물이 낙하될 때 그 낙수지점이 침식되는 세굴현상(D)과 물받이(3)의 기초면 보다 더욱 깊숙한 부위까지 침식되는 파이핑(P) 현상에 의해 물받의 지지력이 상실되면서 이에 균열이나 파손이 발생되는 문제점이 있었다.On the other hand, the conventional blown beam made of a concrete structure, as shown in Figure 2 when the water falls to the downstream of the drip tray (3) extending over the upper surface (2) of the structure (1) to the inclined surface scour phenomenon that the fall point is eroded There was a problem that cracks or breakage occurred due to the loss of the bearing capacity of the drip tray due to the piping (P) phenomenon eroded to a portion deeper than the base surface of the (D) and the drip tray (3).
본 발명은 위와 같은 종래의 철근 콘크리트 구조물로 된 물막이 보의 문제점을 감안하여 안출한 것으로, 그 목적은 자연환경에 친화적이면서 내구성을 향상시킬 수 있는 자연석을 이용한 취수용 취입보의 설치공법을 제공하는 것이다.The present invention has been made in view of the problems of the water barrier beam made of a conventional reinforced concrete structure as above, the object is to provide an installation method of the intake blower using a natural stone that can improve the durability while being friendly to the natural environment. .
이러한 목적을 달성하기 위한 본 발명은, 하천에 물을 담수되게 하는 취입보의 물막이벽을 담수량에 따른 최대 수압을 계산하여 이에 대응하는 두께로 축조하고, 상기 물막이벽의 담수면 반대측 물받이부는 월류된 물을 경사지게 흐르도록 다수의 대립형 자연석의 상부면을 하향으로 경사지게 배열하되, 상기 대립형 자연석으로 된 물받이부의 기초면에는 침투수에 의한 파이핑을 방지하게 지면의 상층에 부직포와 조립돌을 적층시공하며, 상기 물받이부의 경사하단부에는 자연석을 잔류되게 구속하는 지지턱을 설치함으로써, 취입보의 구성소재를 하천에 산재된 자연석으로 대체하여 환경 및 생태계에 친화적으로 함과 아울러 월류수의 낙수에 의한 세굴현상 및 침투수에 의한 파이핑 현상을 최소화함을 특징으로 한다.The present invention for achieving the above object is to construct a water barrier wall of the blown beam to allow fresh water in the river to calculate the maximum water pressure according to the amount of fresh water and to build a thickness corresponding thereto, and the drip tray part opposite the fresh water surface of the water barrier wall is overflowed water Arrange the upper surface of the plurality of all natural natural stones inclined downward so as to flow obliquely, and the non-woven fabric and the granulated stone is laminated on the upper layer of the ground to prevent piping by the infiltration water on the base surface of the drip tray made of the all natural natural stone In addition, by installing a support jaw restraining the natural stone remaining at the inclined lower end of the drip tray part, by replacing the constituent material of the blow beam with natural stones scattered in the river, it is friendly to the environment and ecosystem, and scour phenomenon and infiltration by the overflow of the overflow It minimizes the piping phenomenon by water.

이하, 본 발명의 자연석을 이용한 취수용 취입보의 설치공법을 첨부도면을 참조하여 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the installation method of the intake blower using a natural stone of the present invention will be described.
도 3은 본 발명의 실시예의 자연석을 이용한 취수용 취입보의 설치공법을 나타낸 단면구성도로서, 하천의 폭방향으로 설치되어 물을 담수되게 하는 취입보의 물막이벽(10)을 담수량에 따른 최대 수압을 계산하여 이에 대응하는 두께로 축조하고, 상기 물막이벽(10)의 상부를 타고 넘쳐흐르는 하류측에는 월류된 물이 경사지게 흐르면서 요철에 의해 유속이 감소되도록 다수의 대립형 자연석(21)을 하향으로 경사지게 배열한 물받이부(20)를 설치한다.Figure 3 is a cross-sectional view showing the installation method of the water intake blower using the natural stone of the embodiment of the present invention, the maximum water pressure according to the fresh water in the water barrier wall 10 of the blown water installed in the width direction of the river to the fresh water Calculate and build a corresponding thickness, and the plurality of allelic natural stones 21 are inclined downward so as to reduce the flow rate due to unevenness while the overflowed water flows obliquely on the downstream side of the water barrier wall 10. Install a drip tray 20.
상기 대립형 자연석으로 된 물받이부(20)의 기초면(F)에는 침투수에 의한 파이핑 현상을 방지하게 지면이 접촉되는 부위로부터 상부측을 향하여 부직포(22)와 조립물로 된 자갈(23)을 순차적으로 적층 시공한다.The base surface F of the drip tray part 20 made of the opposed natural stone gravel 23 made of non-woven fabric 22 and granulated material toward the upper side from the site where the ground contact is prevented to prevent the phenomenon of piping caused by the infiltration water. To be laminated sequentially.
상기 자연석(21)과 부직포(22) 및 자갈(23)을 적층하여 된 물받이부(20)의 경사하단부에는 적층된 골재의 유실을 차단하면서 잔류되게 구속하는 지지턱(30)을 설치한다.At the lower end of the inclined bottom of the drip tray 20 formed by stacking the natural stone 21, the nonwoven fabric 22, and the gravel 23, a supporting jaw 30 is provided to restrain the remaining aggregate while remaining.
이때, 상기 지지턱(30)은 담벼락 형태로 일체로 연결되게 축조하는 것이 바람직하나, 말뚝과 같이 부분적으로 형성하는 것도 가능하다.At this time, the support jaw 30 is preferably constructed to be connected integrally in the form of a wall, it is also possible to form a partial, such as a pile.
따라서, 상기와 같은 본 고안은 담수하기 위한 물의 수위를 계산하여 하천의 폭방향으로 물막이벽(10)을 축조하고, 이의 하류측에 적당한 거리를 두고 지지턱(30)을 축조한 후 그 사이의 지면에 부직포(22)와 자갈(23) 및 자연석(21)을 순차적으로 적층하여 물받이부(20)를 형성함으로써, 상기 물막이벽(10)을 넘쳐흐르는 물이 물받이부(20)를 흐를 때 평편한 경사면으로 된 종래의 콘크리트 구조물에 비해 불규칙한 요철면으로 된 자연석이 의해 조도계수가 높게되어 유속을 느리게 하므로 하류측 낙수지점에 나타나는 세굴현상을 최소화하게 된다.Therefore, the present invention as described above to construct the water barrier wall 10 in the width direction of the river by calculating the water level for fresh water, and after the support jaw 30 is constructed at an appropriate distance on the downstream side therebetween By sequentially stacking the nonwoven fabric 22, the gravel 23, and the natural stone 21 on the ground to form a drip tray 20, when the water flowing over the drip wall 10 flows into the drip tray 20, Compared to the conventional concrete structure with one slope, the natural stone with irregular irregularities makes the roughness coefficient high and slows down the flow rate, thereby minimizing scour at the downstream side of the downfall.
특히, 물받이부(20)의 표면을 형성하는 대립형의 자연석(21)은 내충격 및 내마모성이 높게 되어 내구수명이 향상되고, 물받이부(20)의 기초에 부직포(22)와 자갈(23)이 시공되어 있으므로 침투수에 의한 지면의 파이핑 현상이 방지된다.In particular, the natural stone 21 of the opposite type forming the surface of the drip tray 20 has a high impact resistance and abrasion resistance, and thus improves the service life, and the nonwoven fabric 22 and the gravel 23 are formed on the base of the drip tray 20. Since it is constructed, the piping of the ground caused by the infiltration water is prevented.
또한 상기 물받이부(20)의 구성소재인 자연석(21)과 자갈(23) 등은 국내의 지리적 여건상 산간지역은 물론 대부분의 자연하천에 산재되어 있으므로, 골재의 준비 또는 조달이 비교적 용이하고 경제적이며, 물받이부(20) 자체가 많은 틈을 가지고 있으므로 콘크리트 취입보에서와 같이 별도의 어도(魚道)를 설치하지 않아도 가능하게 되어 시공또한 용이하다.In addition, since the natural stone 21 and the gravel 23, which are components of the drip tray 20, are scattered in mountainous regions as well as most natural rivers in Korea, the preparation or procurement of aggregate is relatively easy and economical. And, since the drip tray 20 itself has many gaps, it is possible to install even without installing a separate fishery (콘크리트 道) as in the concrete blown beam is also easy to construct.
한편, 본 발명의 방법으로 시공된 취입보는 물이 담수되는 물막이벽 부위의 일부분이 콘크리트로 되고 나머지부분은 자연골재를 조적하여 시공됨으로써, 보수유지가 용이하며, 철거시에도 콘크리트 폐기물의 발생이 적게 되어 환경에 친화적임은 물론 수생 생태환경에도 기여할 수 있다.On the other hand, the blow beam constructed by the method of the present invention is a part of the wall portion of the wall where the water is fresh water is made of concrete and the rest of the natural aggregates are installed, so that easy maintenance and maintenance, less generation of concrete waste during demolition They are environmentally friendly and can contribute to the aquatic ecological environment.
이와 같은 본 발명의 자연석을 이용한 취수용 취입보의 설치공법은 그 구성소재의 대부분이 자연에 방치 및 산재된 골재를 이용하여 축조함으로써, 환경 및 생태계에 친화적인 역활을 함과 아울러 월류수의 낙수에 의한 세굴현상 및 침투수에 의한 파이핑 현상을 최소화할 수 있는 효과가 있으며, 취입보의 내구수명을 연장시킴과 아울러 보수유지를 용이하게 할 수 있는 장점이 있다.The installation method of the intake blower using the natural stone of the present invention is constructed by using the aggregates of most of its constituent materials left and scattered in nature, and play a role of being friendly to the environment and ecosystem, It has the effect of minimizing the scour phenomenon and the piping phenomenon due to the infiltration water, and has the advantage of extending the service life of the blown beam and facilitating maintenance.
