Description

조립식 보강토 옹벽 {a plantable reinforced earth wall}Prefabricated Reinforced Earth Retaining Wall {a plantable reinforced earth wall}

본 고안은 조립식 보강토 옹벽에 관한 것으로, 더욱 상세하게는 옹벽 블록이 띠형 섬유보강재에 의해 보강토체에 지지되도록 마련된 조립식 보강토 옹벽의 구조에 관한 것이다. The present invention relates to a prefabricated reinforcement earth retaining wall, and more particularly to a structure of a prefabricated reinforcement earth retaining wall provided so that the retaining wall block is supported on the reinforcement soil by the band-shaped fiber reinforcement.

일반적으로 대규모 도로공사나 단지조성용 토목용 옹벽으로 주로 사용되는 조립식 보강토 옹벽은 옹벽를 형성하는 옹벽블록을 공장에서 성형하여 옹벽 축조와 보강토 성토 작업을 동시에 수행할 수 있도록 마련된 것을 가리킨다. In general, prefabricated reinforcement retaining wall, which is mainly used for civil engineering retaining wall for large-scale road construction or complex construction, indicates that the retaining wall block forming the retaining wall is molded at the factory to perform retaining wall construction and reinforcement soil filling work at the same time.

이러한 조립식 보강토 옹벽은 상하 및 좌우방향을 따라 상호 인접하게 배열되는 복수개의 옹벽블록으로 마련되는 옹벽과, 상기 옹벽의 후방에 보강토를 다져 형성되는 보강토체를 구비한다.The prefabricated reinforcement retaining wall has a retaining wall provided with a plurality of retaining wall blocks arranged adjacent to each other in the vertical direction and the left and right directions, and a reinforcing soil formed by reinforcing soil at the rear of the retaining wall.

이러한 조립식 보강토 옹벽은 수직방향으로 작용하는 토압에 의해 보강토체가 횡방향으로 변형될 경우 옹벽이나 보강토체가 붕괴될 우려가 있다. Such a prefabricated reinforcement soil retaining wall may collapse the retaining wall or reinforcement soil when the reinforcement soil is deformed in the transverse direction by the earth pressure acting in the vertical direction.

이를 방지하기 위해 조립식 보강토 옹벽 중에는 띠형 섬유보강재를 이용하여 옹벽과 보강토체의 사이의 지지력을 증대시킴으로써 옹벽 및 보강토체 붕괴를 억제한 것이 있다. In order to prevent this, some of the prefabricated soil retaining walls have suppressed collapse of the retaining wall and the reinforced soil by increasing the bearing force between the retaining wall and the reinforced soil by using a strip-shaped fiber reinforcement.

이러한 조립식 보강토 옹벽에서 띠형 섬유보강재는 한 쪽을 통해 각 옹벽블록에 연결되며, 띠형 섬유보강재의 다른 쪽은 보강토체를 형성하기 위한 보강토의 포설과정에서 보강토체에 매설되어 고정된다. In the prefabricated reinforcement retaining wall, the strip-shaped fiber reinforcement is connected to each retaining wall block through one side, and the other side of the strip-shaped fiber reinforcement is buried in the reinforcement soil in the process of laying reinforcement soil to form the reinforcement soil.

띠형 섬유보강재의 연결을 위해 옹벽블록의 후면에는 연결고리 등이 마련된 브래킷부재가 체결부재를 통해 고정되며, 띠형 섬유보강재는 이러한 브래킷부재에 또 다른 체결부재를 이용하여 고정된다. A bracket member provided with a connecting ring is fixed to the rear of the retaining wall block for the connection of the strip-shaped fiber reinforcement through the fastening member, and the strip-shaped fiber reinforcement is fixed to the bracket member using another fastening member.

옹벽블록에 연결된 띠형 섬유보강재에서 옹벽블록 반대 쪽 단부는 상부에 보강토를 포설하는 과정에서 느슨해지지 않도록 옹벽블록 후방 쪽으로 팽팽하게 당겨진 상태에서 앵커핀 등을 통해 보광토체에 고정된다. In the strip-shaped fiber reinforcement connected to the retaining wall block, the opposite end of the retaining wall block is fixed to the light retaining body through an anchor pin while being pulled tightly toward the rear of the retaining wall block so as not to be loosened in the process of laying the reinforcing soil at the top.

따라서 이와 같이 옹벽블록과 보강토체 사이가 보강토체에 매설되는 띠형 섬유보강재를 통해 연결된 상태에서는 보강토와 띠형 섬유보강재 간의 마찰작용에 의해 보강토체의 전단강도가 증진되면서 보강토체 및 옹벽의 붕괴가 예방되는 것이다.Therefore, in the state in which the retaining wall block and the reinforcement soil are connected through the band-shaped fiber reinforcement embedded in the reinforcement soil, the shear strength of the reinforcement soil is enhanced by the friction action between the reinforcement soil and the band-shaped fiber reinforcement, thereby preventing the collapse of the reinforcement soil and the retaining wall. will be.

다음은 본 고안의 바람직한 일 실시예에 따른 조립식 보강토 옹벽을 첨부된 도면을 참조하여 상세히 설명하도록 한다. Next will be described in detail with reference to the accompanying reinforcement retaining wall retaining wall according to an embodiment of the present invention.

도 1에 도시된 바와 같이, 본 실시예에 따른 조립식 보강토 옹벽은 상하 및 좌우방향을 따라 상호 인접하게 배열되는 복수개의 옹벽블록(10)으로 구성되는 옹벽(1)과, 옹벽(1)의 후방에 보강토를 다져 형성되는 보강토체(2)를 구비한다. 최 하부 옹벽블록(10)의 아래쪽에는 기초블록(20)이 깔릴 수 있고, 최 상부 옹벽블록(10)의 위쪽에는 마감블록(30)이 설치될 수 있다. As shown in FIG. 1, the prefabricated reinforcement retaining wall according to the present embodiment includes a retaining wall 1 composed of a plurality of retaining wall blocks 10 arranged adjacent to each other in a vertical direction and a left and right direction, and a rear of the retaining wall 1. It is provided with a reinforcement soil (2) formed by reinforcing the reinforcement soil. The base block 20 may be laid below the bottom retaining wall block 10, and the finishing block 30 may be installed above the top retaining wall block 10.

이러한 조립식 보강토 옹벽은 최 하부 쪽 옹벽 블록 열(A)을 배열한 상태에서 배열된 옹벽 블록 열(A) 후방으로 보강토를 포설하고 다져서 보강토체(2)를 형성한 후 다시 최 하부 쪽 옹벽블록 열(A) 상부에 다음 번 옹벽블록 열(B)을 쌓고, 그 후방 쪽으로 다시 보강토를 포설하고 다지는 과정을 반복하여 옹벽(1) 축조와 보강토(2) 성토 작업을 번갈아 가면서 동시에 수행하여 제작된다. The prefabricated reinforcement retaining wall is laid in the bottom retaining wall block row (A) in the state of arranging the reinforcement soil behind the retaining wall block row (A) arranged and compacted to form the reinforcement soil (2), and then the bottom retaining wall block row (A) The next retaining wall block row (B) is stacked on the upper side, and the reinforcement soil is laid and compacted again toward the rear side, and the retaining wall (1) construction and reinforcement soil (2) are carried out at the same time alternately.

수직방향으로 작용하는 토압에 의해 보강토체(2)가 횡방향으로 변형될 경우 옹벽(1)이나 보강토체(2)가 붕괴될 우려가 있으므로, 옹벽(1)과 보강토체(2) 사이의 지지력을 증대시켜 보강토의 횡방향 변형을 억제하기 위해 각각의 옹벽블록(10)은 띠형 섬유보강재(40)를 통해 보강토체(2)에 지지되도록 마련된다. Since the retaining wall 1 or the reinforcement soil 2 may collapse when the reinforcement soil 2 is deformed in the lateral direction by the earth pressure acting in the vertical direction, the bearing force between the retaining wall 1 and the reinforcement soil 2 is reduced. Each retaining wall block 10 is provided to be supported on the reinforcement soil 2 through the band-shaped fiber reinforcement 40 in order to suppress the transverse deformation of the reinforcement soil.

띠형 섬유보강재(40)는 폴리에스테르계 재질의 심재를 피복재로 감싸 마련될 수 있으며, 두께보가 폭이 넓은 띠 형상으로 마련되는데, 이러한 띠형 섬유보강재(40)는 한 쪽을 통해 개별 옹벽블록(10)에 연결되고, 띠형 섬유보강재(40)의 다른 한쪽은 보강토체(2)를 형성하기 위한 보강토의 포설과정에서 보강토체(2)에 매설되어 고정된다.  The strip-shaped fiber reinforcement 40 may be provided wrapped with a core material of the polyester-based material, the thickness of the beam is provided in a wide band shape, such a strip-shaped fiber reinforcement 40 is an individual retaining wall block 10 through one side The other side of the strip-shaped fiber reinforcement 40 is embedded in the reinforcement soil (2) in the process of laying the reinforcement soil for forming the reinforcement soil (2) is fixed.

따라서 이와 같이 옹벽(1)을 형성하는 각각의 옹벽블록(10)과 보강토체(2) 사이가 보강토체(2)에 매설되는 띠형 섬유보강재(40)를 통해 연결된 상태에서는 보강토와 띠형 섬유보강재(40) 간의 마찰작용에 의해 보강토체(2)의 전단강도가 증진되면서 보강토체(2) 및 옹벽(1)의 붕괴를 예방할 수 있게 된다.
Therefore, the reinforcing soil and the band-like fiber reinforcement in the state where the retaining wall block 10 and the reinforcement soil 2 forming the retaining wall 1 are connected through the band-like fiber reinforcement 40 embedded in the reinforcement soil 2. As the shear strength of the reinforcement soil 2 is enhanced by the friction action between 40, the collapse of the reinforcement soil 2 and the retaining wall 1 can be prevented.

한편, 본 실시예에 따른 조립식 보강토 옹벽은 보다 신속하게 시공될 수 있도록 띠형 섬유보강재(40)의 설치 구조가 간소화 된다. On the other hand, the prefabricated reinforced soil retaining wall according to the present embodiment is simplified in the installation structure of the strip-shaped fiber reinforcement 40 so that it can be constructed more quickly.

보다 상세히 설명하자면, 도 2 내지 도 5에 도시된 바와 같이, 본 실시예에 따른 조립식 보강토 옹벽에 있어서 각 옹벽블록(10)의 내부에는 띠형 섬유보강재(40)의 고정을 위한 고정홀(11)이 마련된다. 이러한 고정홀(11) 내부에는 걸림부재(50)가 걸려 지지되도록 마련되며, 띠형 섬유보강재(40)는 걸림부재(50)를 걸림방향으로 당길 수 있도록 걸림부재(50)에 감겨진 상태로 옹벽블록(10)에 연결된다. More specifically, as shown in Figures 2 to 5, in the prefabricated reinforcement retaining wall according to the present embodiment, each retaining wall block 10 in the interior of the fixing hole 11 for fixing the band-shaped fiber reinforcement 40 Is provided. The fixing hole 11 is provided in such a manner that the locking member 50 is caught and supported, and the strip-shaped fiber reinforcement 40 is retained in the retaining wall while being wound around the locking member 50 so as to pull the locking member 50 in the locking direction. Connected to block 10.

이때 띠형 섬유보강재(40)는 일단이 고정홀(11)로 집입되어 고정홀(11)에 걸려 있는 걸림부재(50)에 감긴 상태로 다시 고정홀(11) 외부로 인출되고, 고정홀(11) 외부로 인출된 띠형 섬유보강재(40)의 양단은 상호 포개어지고 옹벽블록(10) 후방 쪽으로 당겨진 상태에서 앵커핀 등의 고정부재(60)를 통해 보강토체(2)에 고정된다. At this time, the strip-shaped fiber reinforcing material 40 is one end is inserted into the fixing hole 11 and drawn out to the outside of the fixing hole 11 in the state wound around the locking member 50 hanging on the fixing hole 11, the fixing hole 11 ) Both ends of the strip-shaped fiber reinforcement 40 drawn to the outside is superimposed on each other and fixed to the reinforcement soil 2 through a fixing member 60 such as an anchor pin in a state of being pulled toward the rear of the retaining wall block 10.

따라서 이와 같은 띠형 섬유보강재(40)의 설치구조에서는 옹벽 블록(10)에 걸림부재(50)가 걸려 지지되는 고정홀(11)을 형성하고, 고정홀(11)에 걸림부재(50)를 단순히 걸려 지지되도록 위치시킨 상태에서 띠형 섬유보강재(40)를 걸림부재(50)에 감기도록 두르기만 하면 띠형 섬유보강재(40)를 옹벽블록(10)에 간단히 연결할 수 있게 되므로, 띠형 섬유보강재(40)를 옹벽 블록(10)에 연결하기 위해 옹벽 블록(10)에 연결고리가 마련된 브래킷부재와 같은 구성을 체결부재를 이용하여 고정시키거나 띠형 섬유보강재(40)를 체결부재를 이용하여 브래킷부재에 고정시키는 작업 등이 삭제되어 옹벽블록(10)과 띠형 섬유보강재(40) 간의 연결작업이 간편해지고, 이에 따라 전체 조립식 보강토 옹벽의 시공작업 시간을 단축시킬 수 있게 된다. 상기 고정홀(11)의 경우 옹벽 블록(10)을 제조하기 위한 금형의 형상에 따라 옹벽 블록(10)의 제조시 일체로 형성할 수 있다. Accordingly, in the installation structure of the strip-shaped fiber reinforcement 40, the retaining wall block 10 forms a fixing hole 11 through which the locking member 50 is held, and the locking member 50 is simply attached to the fixing hole 11. The belt-shaped fiber reinforcement 40 can be simply connected to the retaining wall block 10 by simply wrapping the belt-shaped fiber reinforcement 40 to be wound around the catching member 50 in a state where it is supported to be caught. In order to connect the retaining wall block 10 to the retaining wall block 10, a structure such as a bracket member provided with a connecting ring is fixed using a fastening member, or a band-shaped fiber reinforcement 40 is fixed to the bracket member using a fastening member. The operation of the retaining wall block 10 and the strip-shaped fiber reinforcement 40 is simplified, and thus, the construction time of the entire prefabricated soil retaining wall can be shortened. The fixing hole 11 may be integrally formed at the time of manufacturing the retaining wall block 10 according to the shape of a mold for manufacturing the retaining wall block 10.
