Description

하천용 옹벽{RETAINING WALL FOR RIVER}River retaining wall {RETAINING WALL FOR RIVER}

본 발명은 토목기술분야에 관한 것으로서, 보다 상세하게는 하천의 호안보호를 위한 하천용 옹벽에 관한 것이다.The present invention relates to the field of civil engineering, and more particularly, to a river retaining wall for protection of a river bank.

하천은 큰 강은 물론, 호수 습지 등 육지 표면에서 대체로 일정한 유로를 가지는 유수의 모든 계통을 말한다. Rivers are all streams that have a generally constant flow path on land surfaces, such as large rivers and lake marshes.

이와 같은 하천은 자연상태 그대로 두면 유수에 의한 침식과 침수, 특히 홍수시 수위상승 등으로 인해 호안 및 제방, 도로 등이 파괴, 붕괴된다.If such a river is left in its natural state, lakes, banks, roads, etc. are destroyed or collapsed due to erosion and flooding caused by running water, especially during flooding.

따라서, 하천을 보호하기 위해, 도 1 및 도 2에 도시된 바와 같이 하천(2)의 사면 또는 경사면을 따라 인공적인 암석, 콘크리트를 타설하거나 콘크리트 블록을 이용하여 벽면 형상으로 옹벽(10)을 축조하고 있는 실정이다. Therefore, in order to protect the river, as shown in Figs. 1 and 2, artificial rock, concrete is poured along the slope or slope of the river 2, or the retaining wall 10 is constructed in a wall shape using a concrete block. I'm doing it.

그러나, 옹벽(10)을 축조하더라도 우기, 홍수시와 같이 유속이 매우 빠르거나 수위가 상승하는 경우에는 옹벽(10)을 타고 올라오는 수류(화살표 참조)를 차단하지는 못한다. 따라서, 하천(2)의 범람으로 인한 사고를 막지 못하는 문제점이 있다. 또한, 옹벽(10)을 타고 오르는 수류로 인해 옹벽에 균열이 생겨 파괴되는 것을 방지하지 못하는 문제점이 있다.However, even when the retaining wall 10 is constructed, if the flow rate is very fast or the water level rises, such as during the rainy season or the flood, the water flow up the retaining wall 10 may not be blocked (see arrow). Therefore, there is a problem that can not prevent the accident caused by the flooding of the river (2). In addition, there is a problem that can not be prevented by the cracks generated in the retaining wall due to the current flowing up the retaining wall (10).

특히 하천(2)의 구조적 특성상 하천의 만곡부분(2a)에서 상대적으로 유속이 빨라지기 때문에, 하천(2)의 만곡부분(2a)에서의 수위 상승 및 옹벽(10)의 균열 문제점이 더욱 심각하다.In particular, because of the structural characteristics of the river (2), because the flow rate is relatively faster in the curved portion (2a) of the river, the problem of water level rise in the curved portion (2a) of the river (2) and cracks of the retaining wall 10 is more serious. .

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 홍수시와 같이 유속이 매우 빠르거나 수위가 상승하더라도 수류가 옹벽을 타고 오르는 것을 차단할 수 있는 하천용 옹벽을 제공함을 그 목적으로 한다.The present invention has been made to solve the above problems, it is an object of the present invention to provide a river retaining wall that can block the flow of water flows on the retaining wall even if the flow rate is very fast or the water level is increased, such as during floods.

상기한 과제를 해결하기 위해 본 발명은 하천(2)의 측면을 보호하도록 설치되는 벽체부(110); 상기 벽체부(110)에 상하방향을 따라 복수개가 돌출 형성되며, 각각 상기 하천(2)을 따라 형성된 가로부재(120)를 포함하는 것을 특징으로 하는 하천(2)용 옹벽(100)을 제시한다. In order to solve the above problems, the present invention is a wall portion 110 is installed to protect the side of the river (2); A plurality of protrusions are formed in the wall portion 110 along the up and down direction, and the retaining wall 100 for the river 2 is characterized by including a horizontal member 120 formed along the river 2, respectively. .

상기 가로부재(120)는 수평선에 대하여 수평하게 형성될 수 있다.The horizontal member 120 may be formed horizontally with respect to the horizontal line.

상기 가로부재(120)는 수평선에 대하여 경사지게 형성될 수 있다.The horizontal member 120 may be formed to be inclined with respect to the horizontal line.

상기 가로부재(120)는 상기 하천(2)을 따라 지그재그 형상으로 형성될 수 있다.The horizontal member 120 may be formed in a zigzag shape along the river (2).

상기 가로부재(120)는 상기 하천(2)의 수충부에 위치되도록 형성될 수 있다.The horizontal member 120 may be formed to be located at the receiver of the river (2).

상기 가로부재(120)는 상기 하천(2)의 만곡부분(2a)의 수충부에 위치되도록 형성될 수 있다.The horizontal member 120 may be formed to be located at the receiver of the curved portion 2a of the river 2.

상기 하천(2)을 따라 복수개가 돌출 형성되며, 각각 상하방향을 따라 형성된 세로부재(130)를 더 포함할 수 있다. A plurality of protrusions are formed along the stream 2, and may further include a vertical member 130 formed along the vertical direction.

상기 세로부재(130)는 상기 하천(2)의 만곡부분(2a)의 수충부에 상기 가로부재(120)와 교차하여 형성될 수 있다.The vertical member 130 may be formed to cross the horizontal member 120 at the receiving portion of the curved portion (2a) of the river (2).

상기 세로부재(130)는 상하방향을 따라 수직하게 형성될 수 있다. The vertical member 130 may be formed vertically in the vertical direction.

상기 세로부재(130)는 상하방향을 따라 경사지게 형성될 수 있다. The vertical member 130 may be inclined along the vertical direction.

이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 이하에 도시된 바와 같이, 하천(2)용 옹벽(100)은 하천(2)의 측면을 보호하도록 설치되는 벽체부(110)와, 벽체부(110)에 상하방향을 따라 복수개가 돌출 형성되며 각각 하천(2)을 따라 형성된 가로부재(120)들을 포함할 수 있다.As shown below in FIG. 3, the retaining wall 100 for the river 2 includes a wall portion 110 installed to protect the side surface of the river 2, and a plurality of the retaining walls 100 protrude along the vertical direction. It may be formed and include horizontal members 120 formed along the river (2), respectively.

즉, 하천(2)의 측면(또는 사면, 비탈면, 경사면)이 벽체부(110)에 의해 복개됨으로써 보호될 수 있다. That is, the side surface (or slope, slope, slope) of the river 2 can be protected by being covered by the wall portion 110.

또한 복수의 가로부재(120)들에 의해 벽체부(110)를 타고 오르는 수류(화살표 A 참조)가 차단됨으로써, 다음과 같은 효과를 가질 수 있다. 첫째, 벽체부(110)를 타고 오르는 수류로 인한 수위상승, 나아가 하천(2)의 범람이 방지될 수 있다. 둘째, 벽체부(110)를 타고 오르는 수류가 벽체부(110)에 외력으로 작용하여 벽체부(110)가 균열 등 손상되는 것이 방지될 수 있다. 셋째, 와류 등의 2차류(secondary flow)에 의한 수위상승이 저감될 수 있다. 넷째, 벽체부(110)를 타고 오르는 수류가 복수의 가로부재(120)들에 의해 저항을 받기 때문에 유속이 줄어들 수 있다.In addition, the water flow (see arrow A) that rides up the wall part 110 by the plurality of horizontal members 120 is blocked, thereby having the following effects. First, the rise of the water level due to the water flow up the wall 110, and further flooding of the river (2) can be prevented. Second, the water flow up the wall 110 may act as an external force on the wall 110 to prevent the wall 110 from being damaged such as a crack. Third, the level rise due to secondary flow such as vortex can be reduced. Fourth, the flow rate of the water flow up the wall portion 110 is resisted by the plurality of horizontal members 120 can be reduced in flow rate.

가로부재(120)는 여러가지 형상으로 형성될 수 있다.The horizontal member 120 may be formed in various shapes.

즉, 가로부재(120)는 도 3 및 도 4에 도시된 바와 같이, 수평선에 대하여 수평하게 일자형으로 형성됨으로써, 구조적으로 간소하게 형성될 수 있다.That is, the horizontal member 120, as shown in Figure 3 and 4, is formed in a straight line horizontally with respect to the horizontal line, it can be formed structurally simple.

또는 가로부재(120)는 수평선에 대하여 경사지게 형성됨으로써, 벽체부(110)를 타고 오르는 수류뿐만 아니라 하천(2)의 흐름방향에 따른 수류(화살표 B 참조) 또한 가로부재(120)에 의해 차단됨으로써 우수한 유속 저감 효과도 가질 수 있다.Alternatively, the horizontal member 120 is formed to be inclined with respect to the horizontal line, so that not only the water flowing up the wall portion 110 but also the water flow according to the flow direction of the stream 2 (see arrow B) is also blocked by the horizontal member 120. It can also have an excellent flow rate reduction effect.

또는 가로부재(120)는 도 5에 도시된 바와 같이, 수평선에 대하여 수평한 형태 또는 경사진 형태로 하천(2)을 따라 지그재그 형상으로 형성됨으로써, 전술한 수평선에 대하여 경사진 가로부재(120)와 같이 유속 저감 효과가 우수할 뿐만 아니라 벽체부(110)를 따라 흐르는 수류가 가로부재(120)의 지그재그 형상 안에 갇혀서 보다 효과적으로 상쇄될 수 있다.Alternatively, as shown in FIG. 5, the horizontal member 120 is formed in a zigzag shape along the river 2 in a horizontal or inclined form with respect to the horizontal line, thereby inclined with respect to the horizontal line described above. As well as excellent flow rate reduction effect, the water flow flowing along the wall portion 110 is trapped in the zigzag shape of the horizontal member 120 can be more effectively offset.

이와 같은 가로부재(120)는 벽체부(110)의 하부부터 상부까지 전 높이에 걸쳐 형성될 수 있으나, 벽체부(110)를 타고 오르는 수류 저감에 충실하면 되므로 도시된 바와 같이 상하방향을 따라 하천(2)의 수면 위 부분인 하천(2)의 수충부에 위치되도록 형성되는 것이 재료비 비용 절감 등의 측면에서 보다 유리하다. 가로부재(120)는 하천(2)을 따라 전체에 형성될 수도 있으나, 구조적 특성 상 하천(2)의 만곡부분(2a)에서 상대적으로 유속이 빨라지고 유속 저항이 커 주로 수위 상승이 발생하는 곳인 바 비용 절감 등의 측면에서 하천(2)의 만곡부분(2a)에 한정하여 형성되는 것이 바람직하다.Such horizontal member 120 may be formed over the entire height from the lower portion to the upper portion of the wall portion 110, but since it is necessary to faithfully reduce the water flow up the wall portion 110 as shown in the river It is more advantageous in that it is formed so as to be located in the waterway portion of the river 2, which is the upper portion of the water surface in (2). Horizontal member 120 may be formed throughout the river (2), but due to its structural characteristics, the flow rate is relatively fast in the curved portion (2a) of the river (2) is a place where the water level rise mainly occurs It is preferable to form only the curved part 2a of the river 2 in terms of cost reduction.

또한 본 발명의 하천(2)용 옹벽(100)은 하천(2)을 따라 복수개가 돌출 형성되며, 각각 상하방향을 따라 형성된 세로부재(130)들을 더 포함할 수 있다. 즉, 복수의 세로부재(130)들에 의해 하천(2)의 흐름방향에 따른 수류(화살표 B 참조)가 저항을 받음으로써, 유속이 현격히 줄어들 수 잇다.In addition, the retaining wall 100 for the river 2 of the present invention is formed with a plurality of protrusions along the river 2, each may further include a vertical member 130 formed in the vertical direction. That is, the water flow (see arrow B) along the flow direction of the stream 2 is received by the plurality of vertical members 130, the flow rate can be significantly reduced.

세로부재(130)는 전술한 가로부재(120)처럼 여러가지 형상으로 형성될 수 있다. 즉 세로부재(130)는 상하방향을 따라 수직 또는 경사지게 형성되거나 지그재그 형상 등으로 형성될 수 있다.The vertical member 130 may be formed in various shapes like the horizontal member 120 described above. That is, the vertical member 130 may be formed vertically or inclined along a vertical direction or may be formed in a zigzag shape.

세로부재(130) 또한 하천(2)의 수면 위 수류 저감에 충실하면 되므로, 상하방향을 따라 하천(2)의 수충부에 위치되도록 형성될 수 있다. 세로부재(130) 또한 가로부재(120)처럼 하천(2)의 만곡부분(2a)에 한정하여 형성될 수 있다.The vertical member 130 may also be formed so as to be located at the receiving portion of the river 2 along the up and down direction, since it is necessary to faithfully reduce the water flow on the surface of the river 2. The vertical member 130 may also be formed to be limited to the curved portion 2a of the river 2 like the horizontal member 120.

또한 세로부재(130)는 가로부재(120)에 의한 수류 상승 억제 효과와 세로부재(130)에 의한 유속 저감 효과가 함께 이루어질 수 있도록, 하천(2)의 만곡부분(2a)의 수충부에 가로부재(120)와 교차하여 형성될 수 있다.In addition, the vertical member 130 is transverse to the receiving portion of the curved portion (2a) of the river (2) so that the effect of increasing the flow of water by the horizontal member 120 and the effect of reducing the flow rate by the vertical member 130 together It may be formed to intersect the member 120.

이와 같은 벽체부(110) 및 가로부재(120), 나아가 세로부재(130)는 여러가지 소재 및 구조, 공법으로 형성될 수 있으며, 특히 구조적 안전성 등을 위해 콘크리트 구조물로 일체로 형성될 수 있다. Such wall portion 110 and the horizontal member 120, and furthermore the vertical member 130 may be formed by various materials, structures, methods, in particular can be integrally formed of a concrete structure for structural safety and the like.

여기서, 벽체부(110)를 타고 오르는 수류를 효과적으로 차단하기 위해 도시된 바와 같이 가로부재(120)가 세로부재(130)보다 더 많이 돌출될 수 있다.Here, the horizontal member 120 may protrude more than the vertical member 130 as shown in order to effectively block the water flow up the wall portion 110.

이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에만 한정되는 것은 아니며, 특허청구범위에 기재된 범주 내에서 적절하게 변경 가능한 것이다. Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
