본 발명은 지반을 성토해 가면서 구축하는 옹벽구조 및 옹벽의 시공방법에 관한 것으로, 특히 시공을 간편하게 할 수 있는 동시에, 성토지반에 매립되는 메시형 보강재의 정착력을 크게 증대할 수 있는 옹벽구조 및 옹벽의 시공방법에 관한 것이다.The present invention relates to a retaining wall structure and a method of constructing a retaining wall that are constructed while laying ground, and in particular, a retaining wall structure capable of simplifying the construction and greatly increasing the anchoring force of the mesh type reinforcement embedded in the ground It relates to the construction method of a retaining wall.

종래의 옹벽구조는, 도1a 및 도1b에서 도시한 바와 같이, 옹벽의 표면을 형성하는 표면재(10)와, 상기 표면재(10)에 연결되고 뒷부분의 성토지반에 매립되어 정착되는 편평한 플랫형 보강재(20a)로 구성된다.In the conventional retaining wall structure, as shown in FIGS. 1A and 1B, a flat flat reinforcement member is formed on the surface member 10 forming the surface of the retaining wall, and is connected to the surface member 10 and embedded in the backfill soil. It consists of 20a.

이와 같이 종래의 옹벽구조는, 성토지반에 정착되는 편평한 플랫형 보강재(20a)가 별도의 앵커부를 갖지 않으므로, 플랫형 보강재(20a)가 충분하게 정착되도록 지반 내부에 깊이 매립시켜야 한다. 따라서, 플랫형 보강재(20a)를 깊히 매립하기 위해 절토 및 성토작업이 상대적으로 확대될 수 밖에 없으며, 이로 인하여 전반적인 공사의 기간이 길어지고 공사비가 증대되는 문제가 있다.As such, the conventional retaining wall structure has to be embedded deeply in the ground so that the flat reinforcement (20a) is fixed to the fill ground does not have a separate anchor, so that the flat reinforcement (20a) is sufficiently fixed. Therefore, in order to deeply bury the flat reinforcement (20a), the cutting and filling work is inevitably expanded, and thus there is a problem that the overall construction period is long and the construction cost is increased.

본 발명의 목적은, 상기한 종래의 옹벽공사에 대한 문제점을 해결하기 위하여 옹벽공사를 간편하게 할 수 있는 동시에, 구조적으로도 견고하게 시공할 수 있는 옹벽구조 및 옹벽의 시공방법을 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a retaining wall structure and a method of constructing a retaining wall, which can simplify the retaining wall construction and can be constructed structurally, in order to solve the problems of the conventional retaining wall construction described above.

이하, 첨부도면에 도시하는 대표적인 실시예를 통하여 본 발명을 보다 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to exemplary embodiments shown in the accompanying drawings.

도2a는 본 발명에 따른 옹벽구조의 단면도이고, 도2b는 본 발명에 따른 옹벽구조로서 표면재와 보강재의 연결관계를 보여주는 사시도이다.Figure 2a is a cross-sectional view of the retaining wall structure according to the present invention, Figure 2b is a perspective view showing the connection between the surface material and the reinforcement as the retaining wall structure according to the present invention.

본 발명의 옹벽구조는, 옹벽의 표면을 형성하는 표면재(10)와, 상기 표면재(10)에 연결되고 뒷부분의 성토지반에 매립되어 정착되는 메시형의보강재(20)를 포함하여 구성되는 것에 있어서, 상기 메시형의 보강재(20)는 정착력을 증대하도록 성토지반에 매립되는 일부분을 절곡하여 앵커부(30)를 형성하는 것을 특징으로 한다.In the retaining wall structure of the present invention, the retaining wall structure includes a surface material 10 forming a surface of the retaining wall, and a mesh-shaped reinforcement material 20 connected to the surface material 10 and embedded in the backfill soil of the rear part. The reinforcing member 20 of the mesh type is characterized in that the anchor portion 30 is formed by bending a portion embedded in the ground to increase the fixing force.

여기서, 상기 표면재(10)는 블록, 석재, 통나무, 판넬 등 어떤 것을 사용하여도 무방하다. 다만, 표면재(10)에 연결홈을 형성하든가 연결핀 또는 볼트 및 너트 등으로 메시형의 보강재(20)가 견고하게 연결되는 것이 필요하다.Here, the surface material 10 may be any block, stone, log, panel or the like. However, it is necessary to form a connection groove in the surface material 10 or the mesh type reinforcement 20 is firmly connected with a connection pin or a bolt and a nut.

앵커부(30)는 메시형의 보강재(20)의 끝부분에 형성되는 것이 바람직하나, 일정간격마다 형성할 수도 있다. 앵커부(30)를 형성하는 방법은, 주로 메시형의 보강재의 끝부분을 둥글게 절곡함으로써 용이하게 형성시킬 수 있다. 이 때, 절곡된 끝부분이 벌어지지 않도록 철선 등으로 묶어주는 것이 바람직하다.The anchor portion 30 is preferably formed at the end of the mesh type reinforcement 20, but may be formed at regular intervals. The method of forming the anchor portion 30 can be easily formed mainly by bending the end of the mesh-shaped reinforcing material roundly. At this time, it is preferable to bundle with an iron wire so that the bent end does not open.

따라서, 본 메시형의 보강재(20)는 단면 형상이 상대적으로 큰 앵커부(30)를 형성함으로써 정착력이 크게 증대됨은 물론, 상대적으로 정착깊이를 줄일 수 있으므로 절토 및 성토작업을 축소시킬 수 있다.Therefore, the mesh reinforcement 20 is formed by the anchor portion 30 having a relatively large cross-sectional shape, the anchoring force is greatly increased, and the anchoring depth can be reduced relatively, so that cutting and filling work can be reduced. .

한편, 메시형의 보강재(20)의 구조적 강도를 증대하기 위해 수개의 보강 리브(31)를 형성하는 것이 바람직하며, 또한, 성토지반에 매립될 경우 정착력을 증대하기 위해 앵커부(30)에 바(bar), 파이프, 앵글 및 철재 등의 보강 정착재(32)를 연결하는 것이 바람직하다.On the other hand, it is preferable to form several reinforcing ribs 31 in order to increase the structural strength of the mesh-shaped reinforcing material 20, and also to the anchor portion 30 to increase the fixing force when embedded in the fill ground It is preferable to connect the reinforcing fixing members 32 such as bars, pipes, angles, and steel materials.

또한, 앵커부(30)의 형태는 상기에서 둥근 원형을 보여주고 있으나, 도3에서 도시한 바와 같이, 단면상으로 삼각형, 사각형 및 오각형 기타 다각형으로 할 수 있다.In addition, although the shape of the anchor portion 30 shows a round circle in the above, as shown in FIG.

상기한 본 발명의 옹벽 시공방법은, 도4에서 도시하는 바와 같이, 옹벽의 표면을 형성하는 표면재(10)를 설치하는 단계와, 상기 표면재(10)에 연결되고 뒷부분의 성토지반에 정착되며 앵커부(30)를 갖는 메시형의 보강재(20)를 설치하는 단계로 이루어지되,Retaining wall construction method of the present invention, as shown in Figure 4, the step of installing the surface material 10 to form the surface of the retaining wall, and is connected to the surface material 10, is fixed to the ground soil of the rear portion anchor It consists of the step of installing the reinforcement 20 of the mesh type having a portion 30,

상기 메시형의 보강재(20)를 설치하는 단계는, 상기 앵커부(30)가 들어갈 공간(40)을 확보하면서 지반을 다지는 단계와, 상기 공간(40)에 앵커부(30)를 삽입하면서 메시형의 보강재(30)를 설치하는 단계와, 상기 앵커부(30) 안에 콘크리트를 타설하는 단계로 이루어진다.The step of installing the mesh type reinforcing material 20, the ground while securing the space 40 to enter the anchor portion 30, and the mesh portion while inserting the anchor portion 30 in the space 40 It comprises a step of installing the reinforcing material of the mold 30, and the step of placing concrete in the anchor portion (30).

즉, 본 발명의 옹벽 시공밥법은 앵커부(30) 삽입 공간(40)을 형성한 지반을 임시 거푸집으로 활용하는 방법이다. 이 때, 공간(40)을 형성하기 위해서 침목을 배치하고, 지반을 다진 후 다시 침목을 빼어 내면 공간(40)을 용이하게 형성할 수 있다.That is, the retaining wall construction method of the present invention is a method of utilizing the ground on which the anchor portion 30 insertion space 40 is formed as a temporary formwork. At this time, the sleeper is disposed in order to form the space 40, the ground 40 can be easily formed by removing the sleeper again after the ground is chopped.

이상에서와 같이 본 발명의 옹벽구조 및 옹벽의 시공방법는, 성토지반에 정착되는 메시형의 보강재에 원형 또는 다각형 형태의 앵커부를 형성하는 한편, 앵커부에 바, 파이프, 앵글 및 철재 등의 보강 정착재를 연결함으로써, 정착력이 크게 증대됨은 물론, 상대적으로 보강재의 정착깊이를 줄일 수 있으므로 시공을 간편하게 할 수 있다.As described above, the retaining wall structure and the method of constructing the retaining wall according to the present invention form a circular or polygonal anchor portion in a mesh-like reinforcement to be fixed to a fill soil, while reinforcing and fixing bars, pipes, angles, and steel to the anchor portion. By connecting the ashes, the fixing force is greatly increased, and the fixing depth of the reinforcing material can be relatively reduced, thereby simplifying the construction.
