본 발명은 하천제방의 후면부 붕괴를 방지하기 위한 구조에 관한 것으로, 더욱 상세하게는 하천의 제방으로부터 역T형옹벽에 작용하는 수평토압을 흡수하도록 하여 역T형옹벽을 보호하고, 제방내로 침투한 수분을 배수할 수 있도록 하여 제방의 붕괴를 방지할 수 있도록 한 하천제방의 후면부 붕괴를 방지하기 위한 구조에 관한 것이다.The present invention relates to a structure for preventing the collapse of the back of the river bank, and more particularly, to protect the reverse T-shaped retaining wall by absorbing the horizontal earth pressure acting on the reverse T-shaped retaining wall from the river bank. It relates to a structure for preventing the collapse of the back of the river bank to allow the water to drain to prevent the collapse of the bank.

일반적으로 하천의 따라 설치되는 제방은 하천과 접하는 법면에만 옹벽을 설치하고, 그 반대편에는 옹벽을 설치하지 않기 때문에 강우량이 많은 장마철에 제방으로 침투한 빗물에 의해 제방의 지지력이 크게 떨어질 뿐만 아니라 하천의 수위가 증가하여 수평토압이 가중되면, 제방의 후면부가 슬라이딩하여 붕괴되는 문제점이 있었다.In general, the dike installed along the stream installs the retaining wall only on the side of the river, and does not install the retaining wall on the other side. When the water level is increased and the horizontal earth pressure is increased, there is a problem that the rear part of the embankment slides and collapses.

이를 방지하기 위해 종래에는 제방의 후면부에 콘크리트 파쇄물이나 쇄석으로 채워진 망태를 설치하고, 말뚝을 박아 망태를 지지하고 있었다.In order to prevent this, in the past, a mantle filled with concrete crushed stone or crushed stone was installed at the rear side of the embankment, and piles were piled to support the mantle.

그러나, 이와 같은 종래 하천제방의 후면부 보호시설은 제방으로 침투한 수분을 배수할 수 있는 구조를 갖추고 있지 않았기 때문에 많은 양의 비가 지속적으로 내리는 경우 지지력을 잃어 붕괴 되는 문제점이 있었으며, 특히 제방으로부터 가해지는 수평토압을 흡수하는 구조가 아닌 단지 저항하는 구조로만 되어 있었기 때문에 수평토압이 장기간에 걸쳐 지속적으로 작용되는 경우 망태를 지지하는 말뚝이 쓰러지는 문제점을 갖고 있었다.However, since the rear protection facility of the conventional river embankment does not have a structure capable of draining water penetrated into the embankment, there is a problem in that it loses its bearing capacity and collapses when a large amount of rain continues to fall. Because it was not a structure that absorbs horizontal earth pressure but only a structure that resists it, there was a problem that the pile supporting the mesh collapses when horizontal earth pressure is continuously operated for a long time.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 그 목적은 하천의 제방으로 침투한 수분을 배출하여 제방의 붕괴를 방지할 수 있고, 제방으로부터 가해지는 수평토압을 흡수함으로써 제방 후면부 보호시설물을 보호할 수 있는 하천제방의 후면부 붕괴를 방지하기 위한 구조를 제공함에 있다.The present invention has been made in order to solve the above problems, the purpose is to discharge the water penetrated into the bank of the river to prevent the collapse of the bank, and to absorb the horizontal earth pressure applied from the bank of the levee rear protection facilities To provide a structure for preventing the collapse of the rear side of the river bank to protect the.

이러한 본 발명의 목적을 달성하기 위하여 하천 제방의 법면 반대편 외측면에 토압흡수용발포재를 개재한 상태에서 역T형옹벽을 설치하고, 제방을 따라 연속 연결하기 위한 턱과 장부촉을 그 역T형옹벽의 좌우측에 형성하며, 그 턱과 장부촉에 각각 체결공을 형성하여 이 체결공을 통해 제방 속으로 배수파이프를 박고, 역T형옹벽의 기초판 상면에 길이방향으로 연속 연결되는 배수로를 형성하며, 역T형옹벽의 수직벽체에는 오목한 요입부를 형성하여 식생판을 삽입하고, 그 식생판의 개구부를 메시로 덮어서 하천제방의 후면부 붕괴를 방지하기 위한 구조가 제공된다.In order to achieve the object of the present invention, the reverse T-shaped retaining wall is installed on the outer surface opposite to the legal side of the river embankment with the earth pressure absorbing foam interposed therebetween, and the jaw and dowels for continuous connection along the bank are reversed T-type It is formed on the left and right sides of the retaining wall, and fastening holes are formed in the jaw and dowel, respectively, and the drain pipe is driven into the bank through the fastening holes, and a drainage passage is connected to the upper surface of the base plate of the reverse T-shaped retaining wall in the longitudinal direction.

이하 본 발명에 따른 작용을 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도1 내지 도5에 도시된 바와 같이 시공하는 과정은 법면(24)이 설치된 곳에 역T형옹벽(40)을 세운 다음 역T형옹벽(40)의 내측면에 토압흡수용발포재(30)를 밀착시킨 후 제방(22)을 쌓게 되면, 역T형옹벽(40)과 제방(22) 사이에 토압흡수용발포재(30)가 개재된다.As shown in FIGS. 1 to 5, the construction process includes establishing an inverted T-shaped retaining wall 40 where the law surface 24 is installed, and then installing a pressure-absorbing foam material on the inner side of the inverted T-shaped retaining wall 40 ( When the dike 22 is stacked after the 30 is in close contact, the earth pressure absorbing foam 30 is interposed between the reverse T-shaped retaining wall 40 and the dike 22.

즉, 역T형옹벽(40)의 좌우측에 형성된 턱(41)과 장부촉(42)을 밀착시키게 되면, 턱(41)과 장부촉(42)에 형성된 체결공(41a)(42a)의 중심이 일치되는데, 이때 체결공(41a)(42a)으로 배수파이프(50)를 박아 넣게 되면, 배수파이프(50)가 제방(22) 속으로 깊게 박히게 된다.That is, when the jaws 41 and the dowels 42 formed on the left and right sides of the inverted T-shaped retaining wall 40 are brought into close contact with each other, the centers of the fastening holes 41a and 42a formed in the jaws 41 and the dowels 42 coincide with each other. In this case, when the drain pipe 50 is driven into the fastening holes 41a and 42a, the drain pipe 50 is deeply driven into the dike 22.

이때 역T형옹벽(40)은 배수파이프(50)에 의해 옆으로 연속해서 이어나갈 수 있으므로 위와 같은 작업을 반복하게 되면, 역T형옹벽(40)이 옆으로 길게 설치된다.At this time, since the reverse T-shaped retaining wall 40 can be continuously continued sideways by the drainage pipe 50, if the above operation is repeated, the reverse T-shaped retaining wall 40 is installed long.

이후 역T형옹벽(40)의 수직벽체(45)에 형성된 요입부(46)에 식생판(60)을 삽입하게 되면, 식생판(60)의 가장자리에 형성된 플랜지(66)의 관통구멍(66a)과 역T형옹벽(40)의 수직벽체(45)에 형성된 앵커구멍(48)이 서로 일치되는데, 이때 앵커볼트(49)를 관통구멍(66a)을 통해 앵커구멍(48)에 결합하게 되면, 식생판(60)이 역T형옹벽(40)에 결합된다.Then, when the vegetation plate 60 is inserted into the recess 46 formed in the vertical wall 45 of the inverted T-shaped retaining wall 40, the through hole 66a of the flange 66 formed at the edge of the vegetation plate 60 ) And the anchor hole 48 formed in the vertical wall 45 of the inverted T-shaped retaining wall 40 coincide with each other, wherein the anchor bolt 49 is coupled to the anchor hole 48 through the through hole 66a. Vegetation plate 60 is coupled to the inverted T-shaped retaining wall 40.

이후 식생판(60)에 형성된 식재부(68)에 토사를 채운 다음 메시(64)를 덮고, 식물(69)을 식재하게 되면, 역T형옹벽(40)의 수직벽체(45)가 자연친화적으로 식생 화되어 쾌적한 환경을 조성하게 된다.Then, after filling the earth and sand in the planting portion 68 formed in the vegetation plate 60, covering the mesh 64, and planting the plant 69, the vertical wall 45 of the inverted T-shaped retaining wall 40 is natural It is vegetated and creates a pleasant environment.

이때 식생판(60)의 개구부(62)를 덮는 메시(64)는 식생판(60)의 식재부(68)에 채워진 토사가 무너져 내리는 것을 방지하는 작용을 하게 되며, 식물(69)의 활착을 돕는 역할을 하게 된다.At this time, the mesh 64 covering the openings 62 of the vegetation plate 60 serves to prevent the soils filled in the planting portion 68 of the vegetation plate 60 from collapsing. You will be helping.

한편, 위와 같은 상태에서 제방(22)으로 수분이 유입되어 제방(22)이 많은 양의 수분을 머금게 되면, 배수파이프(50)에 형성된 배수공(54)을 통해 배수파이프(50)의 내부로 수분이 유입되는데, 이때 배수파이프(50) 내부가 수분으로 채워지게 되면, 배수파이프(50)의 후단부를 통해 밑으로 떨어져 역T형옹벽(40)의 수직벽체(45)를 타고 흘러내리면서 역T형옹벽(40)의 기초판(43)에 형성된 배수로(44)에 모여 배출된다.On the other hand, when the water is introduced into the embankment 22 in the above state, when the embankment 22 contains a large amount of water, the water into the drain pipe 50 through the drain hole 54 formed in the drain pipe 50. When the inside of the drain pipe 50 is filled with moisture, it falls down through the rear end of the drain pipe 50 and flows down the vertical wall 45 of the inverted T-shaped retaining wall 40 while being reversed. Collected in the drainage path 44 formed in the base plate 43 of the retaining wall 40 is discharged.

이때 제방(22)의 함수량이 떨어지면서 제방(22)의 유실이나 자연붕괴를 방지하게 된다.At this time, the water content of the dike 22 is reduced to prevent the loss or natural collapse of the dike 22.

그리고, 하천(20)이 만수위가 되면서 제방(22)에 과다한 수압이 작용되면서 역T형옹벽(40)을 향해 작용하는 수평토압이 증대되는 경우 제방(22)과 역T형옹벽(40)의 사이에 개재되어 있는 토압흡수용발포재(30)가 압축되면서 토압을 흡수하게 된다.In addition, when the river 20 becomes full water level and the horizontal earth pressure acting toward the reverse T-shaped retaining wall 40 increases while excessive water pressure is applied to the embankment 22, the dike 22 and the reverse T-shaped retaining wall 40 The earth pressure absorbing foam member 30 interposed therebetween is compressed to absorb the earth pressure.

이상에서 설명한 바와 같은 본 발명은 하천의 제방으로 침투한 수분을 배수파이프에 의해 배수하는 구조로 되어 있기 때문에 수분에 의한 제방붕괴를 방지할 수 있으며, 제방 후면과 역T형옹벽의 수직벽체 사이에 개재된 토압흡수용발포재에 의해 역T형옹벽에 가해지는 수평토압을 흡수하는 구조로 되어 있기 때문에 역T형옹벽이 수평토압에 의해 붕괴되거나 균열되는 것을 방지할 수 있는 효과가 있다.As described above, the present invention has a structure in which the water penetrated into the bank of the river is drained by the drainage pipe, thereby preventing the bank from collapsing due to water, and between the back wall of the bank and the vertical wall of the inverted T-shaped retaining wall. Since the earth pressure absorbing foam interposed therebetween absorbs the horizontal earth pressure applied to the reverse T-shaped retaining wall, the reverse T-shaped retaining wall is prevented from being collapsed or cracked by the horizontal earth pressure.

더 나아가서 본 발명은 역T형옹벽에 설치되어 있는 식생판에 식물을 식재할 수 있도록 되어 있기 때문에 자연친화적인 옹벽구조물을 조성할 수 있으며, 식생판에 설치된 메시에 의해 식물을 활착에 도움을 줄 수 있는 효과가 있다.Furthermore, since the present invention is capable of planting the vegetation plate installed on the inverted T-shaped retaining wall, it is possible to create a nature-friendly retaining wall structure, and to help the plant glide by the mesh installed on the vegetation plate. It can be effective.
