Description

배수 안내구조를 구비하는 옹벽 및 이의 시공방법{RETAINING WALL AND CONSTRUNCTION METHOD OF RETAINING WALL}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining wall having a drain guide structure,

본 발명은 배수 안내구조를 구비하는 옹벽 및 이의 시공방법에 관한 것으로서 좀더 상세하게 설명하면 옹벽의 배수를 보다 완벽하게 해결할 수 있는 옹벽 및 이의 시공방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining wall having a drain guide structure and a method of constructing the retaining wall. More specifically, the present invention relates to a retaining wall and a method of constructing the retaining wall.

일반적으로, 폭우나 홍수와 같은 천재지변에 의하여 산비탈이나 언덕의 경사면이 일부 훼손된 경우에는 훼손된 경사면을 일정량만큼 깎아내고 그 부분에 토사를 메워서 새로운 경사면을 조성하게 되고, 산비탈이나 언덕 부분에 도로나 철도 등을 새로이 개설한 경우에는 산비탈이나 언덕 부분을 일정량만큼 깍아내어 개셜면을 평지화시킨 다음 나머지 부분을 새로운 경사면으로 조성하게 된다. 또한, 하천의 범람방지와 수자원의 효율적 이용을 위하여 하천이나 호수 부근에 조성된 둑이나 제방 또한 토사의 성토로 인한 경사면이 조성되어 있다.In general, when the mountain slope or hill slope is partially damaged by natural disasters such as heavy rains or floods, the damaged slope is cut off by a certain amount and the slope is buried in the slope to form a new slope, When a new railway is opened, a certain amount of slope or hill portion is cut off to flatten the concrete surface, and then the remaining portion is formed as a new slope. In order to prevent flooding of rivers and to utilize water resources effectively, the banks or banks formed near the rivers and lakes are also provided with slopes due to the clayey soil.

이와 같이, 토사를 깍아내거나 메워서 새로운 지형으로 조성한 성토지역이나 절토지역의 불안정한 경사면을 나대지로 방치할 경우에는 폭우나 홍수 등과 같은 여러 가지 자연적인 원인으로 인하여 경사면의 토사가 쉽게 유실됨으로써 번번히 경사면의 복구작업을 수행하여야 할 뿐만 아니라, 심한 경우에는 나대지 상태의 경사면이 붕괴되어 막대한 인명과 재산피해를 유발시킬 위험성이 크기 때문에, 경사면상에 별도의 보강구조물을 설치하여 경사면의 표면활동에 따른 붕괴 및 낙석 등 의 위험요소를 사전에 차단시켜야 한다.In this way, when the unstable slopes of the embankment area or the cut-off area formed by the new topography are shattered or buried, there are many natural causes such as heavy rains and floods, so that the slopes of the slopes are easily lost, In addition, it is necessary to perform a restoration work. In addition, in case of severe case, there is a great risk of causing great damage to people and property due to the collapse of the inclined surface. Therefore, a separate reinforcement structure is provided on the inclined surface, The risk factors such as rockfall should be prevented in advance.

상기한 바와 같은 불안정한 경사면을 안정화시키기 위한 종래의 사면보강공법으로는, 앵커볼트를 사용하여 식생매트와 철망을 경사면상에 고정시킨 다음 철망을 통하여 점성력이 우수한 녹생토 조성물을 취부시키는 아스나 공법과, 천공기를 사용하여 경사면에 일정 깊이의 구멍을 청공시킨 다음 그 구멍에 소일네일과 모르타르를 삽입하여 그라우팅시키는 소일네일링 공법과, 아연도금 철선으로 이루어지는 철망상자 속에 잡석을 채워 경사면의 연약부분에 축조시키는 개비온 공법 및 콘크리트 구조물을 옹벽의 형성을 축조하여 경사면을 지지시키도록 한 콘크리트 옹벽 공법 등이 알려져 있다.Conventional slope reinforcement methods for stabilizing unstable slopes as described above include an asuna method in which a vegetation mat and a wire mesh are fixed on an inclined surface using an anchor bolt and then a rye soil composition having excellent viscous force is installed through a wire mesh, A soilless nailing method in which a hole having a predetermined depth is formed on an inclined surface and a soil nail and a mortar are inserted into the hole to form a grooved nail, a garniture which is filled with rubble in a wire mesh box made of galvanized iron wire, A concrete method and a concrete retaining wall method in which a reinforcing wall is formed to support the inclined surface is known.

특히, 콘크리트 옹벽 공법은 견고함이 매우 우수할 뿐만 아니라 시공후 어느 정도의 기간까지는 별다른 누수나 붕괴의 위험이 없다는 장점은 있으나, 경사면 내부에서 고립된 우수나 지하수가 콘크리트의 내측벽을 침식하에 될 경우 침투수의 동결 및 해빙과정에 콘크리트의 옹벽의 부식과 균열이 매우 따른 속도로 진행되기 때문에 시공 후 지속적인 유지보수가 반드시 병행되어야 하는 문제점이 있었다.In particular, the concrete retaining wall construction method is very robust and has a merit that there is no risk of leakage or collapse until a certain period after the construction. However, when the inner or outer wall of the concrete is eroded, The corrosion and cracking of the retaining wall of the concrete proceed at a rate corresponding to the freezing and thawing process of the infiltration water, so that there is a problem that the continuous maintenance must be performed after the construction.

종래 옹벽(1) 배면의 배면수(背面水)를 배출시키기 위해서 도 1에 도시한 바와 같이 옹벽(1)의 배면에 잡석(2)을 배수구(3) 주변에 설치하되, 토사의 유출을 방지하고자 잡석(2) 주변을 부직포(4)로 감싸 시공토록 하고 있다.In order to discharge the back surface water of the back surface of the retaining wall 1 as shown in Fig. 1, the rubble 2 is installed around the drain port 3 on the back surface of the retaining wall 1, The nonwoven fabric 4 is wrapped around the rubble 2 so as to be constructed.

물론 대한민국 특허공개 제2003-0031084호와 같이 유공 배수관을 토압이 작용하는 범위에 바둑판 형태로 매설하여 배면 수의 배출을 유도하고, 옹벽 연결부에는 인위적으로 투입하는 이물질을 차단할 수 있도록 이물질 방지마개를 이용하여 배수구가 막히는 현상이 없도록 하여 옹벽 전체의 안정성을 배가할 수 있는 옹벽 배수시스템 및 그 시공방법이 출원된 바 있다.
As disclosed in Korean Patent Laid-Open Publication No. 2003-0031084, a drainage pipe is buried in a checkerboard shape in a region where earth pressure acts to induce drainage of the backside water, and a foreign matter prevention cap is used to block foreign substances artificially introduced into the retaining wall connection portion. Thereby preventing the clogging of the drain port, thereby doubling the stability of the entire retaining wall, and a construction method thereof.

그러나 상기와 같은 옹벽 배면에 잡석을 배수구 주변에 설치하는 종래의 방법은 잡석의 부설 범위에 따라 옹벽에 전달되는 수압의 범위가 다르고, 잡석 부위의 배수구가 인위적으로 막히게 될 경우 옹벽에 배면수의 수압이 작용하여 옹벽의 안정성이 떨어지는 단점을 갖는 것이다.However, in the conventional method of installing the rubble around the drainage port on the back surface of the retaining wall as described above, when the range of the water pressure to be transmitted to the retaining wall is different according to the range of the rubble and the drainage port of the rubble is artificially clogged, And the stability of the retaining wall deteriorates.

또한 유공 배수관을 토사에 매설하고 이를 배수관으로 연결하는 종래의 방법은 배수관으로 유도할 수 있는 우수(雨水)의 양이 적고, 토사에 배수관이 막힐 우려가 높은 단점을 갖는 것이다.
Also, the conventional method of embedding the perforated drain pipe in the gravel and connecting it to the drain pipe has a disadvantage that the amount of rainwater that can be guided to the drain pipe is small and the drain pipe is clogged with the gravel.

상기와 같은 목적을 달성하기 위하여 본 발명 배수 안내구조를 구비하는 옹벽은 콘크리트로 옹벽 내측에 옹벽과 일체로 배수유도날개를 형성하고, 상기 배수유도날개 안쪽에는 드레인보드가 옹벽 내측에 밀착되도록 설치되며, 상기 드레인보드의 일측면에 배수유도판과 쇄석층이 밀착되도록 하되 상기 배수유도판과 쇄석층은 상부에서 하부까지 일정간격 이격되도록 다층(多層)으로 형성됨을 특징으로 한다.In order to attain the above object, a retaining wall having a drain guide structure according to the present invention is formed by a drainage guiding vane integrally formed with a retaining wall inside a retaining wall by concrete, and a drain board is installed inside the retaining wall on the inside of the drain guiding vane And a drainage inducing plate and a crushed stone layer are brought into close contact with one side of the drain board, wherein the drainage inducing plate and the crushed stone layer are formed in multiple layers so as to be spaced apart from the upper part to the lower part by a predetermined distance.

또한 본 발명 배수 안내구조를 구비하는 옹벽의 시공방법은 콘크리트로 옹벽을 시공함에 있어 옹벽의 내측에 배수유도날개를 옹벽과 일체로 형성하는 단계와, 상기 배수유도날개 안쪽에 드레인보드를 옹벽의 일측면과 밀착되도록 설치하는 단계와, 상기 드레인보드 일측에 토사를 적층하되 드레인보드를 향해 아래로 경사지게 적층하는 단계와, 상기 적층된 토사 위에 배수유도판을 얹되 상기 배수유도판의 일측단이 드레인보드에 밀착되도록 설치하는 단계와, 상기 배수유도판 위에 쇄석을 일정 높이 적층하는 단계와, 상기 쇄석 위에 다시 토사를 적층하는 단계와, 상기 적층된 토사 위에 다시 배수유도판과 쇄석을 일정 높이 적층하는 단계와, 상기 적층된 토사 위에 다시 한번 배수유도판과 쇄석을 일정 높이 적층하고 그 위에 토사로 덮어서 사면(斜面)을 마무리하는 단계로 이루어짐을 특징으로 한다.
According to another aspect of the present invention, there is provided a method of constructing a retaining wall having a drain guiding structure, comprising the steps of: forming a drain guiding wing integrally with a retaining wall on an inner side of a retaining wall when constructing a retaining wall with concrete; The drainage induction plate is placed on the laminated soil, and one end of the drainage induction plate is connected to the drain board and the drainage board, A step of laminating a stone at a certain height on the drainage induction plate, a step of laminating the soil on the crushed stone, and a step of laminating the drainage induction plate and the crushed stone at a certain height on the laminated soil A drainage induction plate and a crushed stone are once again stacked on the deposited gravel to a predetermined height, and the slurry is covered with a slurry on the slope It characterized by a step of finishing made of an 面).

본 발명은 옹벽 배면에 쇄석층과 배수유도판을 높이와 길이를 달리하여 형성하되 배수유도판이 옹벽 배면을 향해 경사지도록 배치함으로써 표층(表層)부를 타고 흐르던 우수(雨水)가 지층(地層)부로 스며들면서 상기 배수유도판에 의해 드레인보드로 유도되고, 상기 드레인보드로 유도된 우수는 다시 드레인보드와 배수유도날개에 의해 배수공으로 유도되어 빠른 배수를 유도함으로써 배수압력에 의한 옹벽붕괴의 우려를 최소화할 수 있는 것이다. In the present invention, the crushed stone layer and the drainage guide plate are formed on the back surface of the retaining wall at different heights and lengths, and the drainage induction plate is disposed so as to be inclined toward the back surface of the retaining wall, so that rainwater flowing on the surface layer portion seeps into the stratum The drain is guided to the drain board by the drainage guide plate and the drainage leading to the drain board is guided to the drain by the drain board and the drainage guide blade to induce quick drainage to minimize the risk of the drainage wall collapse due to the drainage pressure You can.

또한 본 발명은 잡석(쇄석)을 배수구 주변에 설치하는 종래의 방법에 비해 배수유도판 위에 쇄석을 배치함으로써 넓은 면적에 해당하는 우수의 배수를 유도할 수 있으며, 역시 좁은 면적에 불과한 종래의 유공 배수관에 의한 우수보다 훨씬 많은 유수의 배수가 가능하다.In addition, according to the present invention, it is possible to induce drainage of a large area corresponding to a large area by arranging crushed stones on a drainage induction plate in comparison with a conventional method in which a rubble (crushed stone) is installed around the drainage hole, Which is much higher than the storm water quality.

또 본 발명은 쇄석층과 배수유도판, 드레인보드와 배수유도날개에 의해 순차적으로 우수를 유도하고 배수공을 통해 배수되도록 함으로써 토사에 의한 배수공의 막힘 우려를 현저히 줄일 수 있는 매우 유용한 발명인 것이다.
In addition, the present invention is a very useful invention that can significantly reduce the fear of clogging the drainage hole caused by the gravel by inducing the storm successively by the crushed stone layer, the drainage guide plate, the drain board and the drainage guiding wing, and draining through the drainage hole.

The retaining wall having the drainage guiding structure according to the present invention includes a retaining wall A water drainage guiding vane 110 is formed integrally with a retaining wall on the side of the drainage guiding vane 110 and a drainage hole 101 is positioned at a lower end of the drainage guiding vane 110, The drainage induction plate 130 formed to be inclined downward toward the drain board 120 is formed on the other side of the drainage board 120 so as to be in close contact with the inner side surface of the retaining wall 100 And the phase The upper multiple guide plate 130, is configured to form a crushed stone layer 160.

이때 상기 배수유도판(130)과 쇄석층(160)의 일단은 드레인보드(120)의 일측면에 밀착되도록 하고, 상기 배수유도판(130)과 쇄석층(160)은 상부에서 하부까지 다층(多層)구조로 형성된다. 이때 다층구조라 함은 배수유도판(130)과 쇄석층(160)이 일정 높이로 서로 이격(離隔)된 상태로 설치됨을 의미한다.At this time, one end of the drainage induction plate 130 and the crushed stone layer 160 are closely attached to one side of the drainboard 120, and the drainage induction plate 130 and the crushed stone layer 160 are connected to one side of the multi- Multilayer) structure. In this case, the multi-layer structure means that the drainage induction plate 130 and the crushed stone layer 160 are spaced apart from each other at a predetermined height.

상기 배수유도날개(110)는 옹벽(100)을 형성하기 위한 거푸집(미도시) 형성시 상기 배수유도날개(110)도 형성될 수 있도록 거푸집을 설치한다. 따라서 상기 거푸집에 콘크리트를 타설하고 양생 후 거푸집을 제거하면 옹벽(100)의 배면에 배수유도날개(110)가 일정 높이로 돌출되도록 형성되는 것이다.The drainage guiding vane 110 is provided with a mold so that the drainage guiding vane 110 can be formed when a mold (not shown) for forming the retaining wall 100 is formed. Therefore, when the concrete is poured into the mold and the mold is removed after curing, the drainage guiding vane 110 is formed to protrude at a predetermined height on the back surface of the retaining wall 100.

상기 배수유도날개(110)의 하부에는 반드시 하나 이상의 배수공(101)이 형성되어야 하며, 이는 배수유도날개(110)에 의해 유도된 우수가 상기 배수공(101)을 통해 배수되도록 하기 위해 필요한 구성이다. 물론 상기 배수공(101)은 원활한 배수를 위해 옹벽(100)에 다수 개 형성될 수도 있음은 당연하다.At least one drainage hole 101 must be formed in the lower part of the drainage guiding vane 110 to ensure that the drainage induced by the drainage guiding vane 110 is drained through the drainage hole 101. Of course, it is a matter of course that a plurality of the drain holes 101 may be formed in the retaining wall 100 for smooth drainage.

또한 본 발명에 있어 상기 배수유도날개(110)는 옹벽(100)의 배면에 밀착되어 형성되는 드레인보드(120)를 지지해주어 안정적인 배수와 드레인보드(120) 설치를 용이하게 하는 기능을 갖는다.In addition, the drainage guiding vane 110 supports the drain board 120 formed in close contact with the back surface of the retaining wall 100 to facilitate stable drainage and facilitate the installation of the drain board 120 in the present invention.

상기 드레인보드(120)는 비용과 시공상의 어려움이 있는 기존 자갈 배수 방법에 비해 진공 성형식 고밀도 폴리스틸렌과 특수성 필터(장섬유 부직포)를 접합시키고, 다수 개의 배수관(유공관) 또는 양수관(Weep Hole)을 구비하여 물의 흐름이 원활하게 하는 배수장치이다.The drain board 120 is formed by joining a vacuum type high density polystyrene and a specificity filter (long fiber nonwoven fabric) to each other and connecting a plurality of drain pipes (pipes) or a weep hole, So that the flow of water is smooth.

상기 배수유도판(130)은 "U"자형상의 홈을 다수 개 구비하는 것으로, 상기 홈에 의해 배수를 유도한다. 특히 상기 배수유도판(130)은 드레인보드(120)를 향해 아래로 기울어진 상태여서 쇄석층(160)을 통과한 우수는 배수유도판(130)에 의해 드레인보드(120) 쪽으로 유도되어 진다. 상기 쇄석층(160)은 배수유도판(130)의 홈이 토사에 의해 막히는 것을 방지하기 위한 구성이다.The drainage guide plate 130 has a plurality of U-shaped grooves, and the drainage is guided by the grooves. Particularly, the drainage induction plate 130 is inclined downward toward the drainboard 120 so that the stormwater that has passed through the crushed stone layer 160 is guided toward the drainboard 120 by the drainage induction plate 130.
