본 발명은 옹벽용 콘크리트 블록, 그 옹벽용 콘크리트 블록의 제조방법, 및 그 옹벽용 콘크리트 블록의 시공방법에 관한 것으로, 좀 더 구체적으로 옹벽블록의 전면부는 골재와 콘크리트가 혼합되어 성형되고, 중간부와 후면부는 콘크리트로 성형되는 단위 옹벽블록을 형성하되, 상기 단위 옹벽블록은 전면부가 서로 붙어서 일체로 성형된 후, 1/2로 절단 연마 제작됨으로써, 전면부의 단면을 더욱 매끄럽고 고급스럽게 형성함은 물론 색상 변질을 방지하며 반영구적 사용이 가능하고, 습식 및 건식으로 제작되는 경우 옹벽블록의 변화를 극소화하여 전면부 표면에 백화 현상이 발생하지 않으며, 색채의 골재를 사용하여서 다양한 색상의 전면부를 형성할 수 있기 때문에 재해 예방은 물론 주변 환경과 잘 조화될 수 있는 옹벽용 콘크리트 블록, 그 옹벽용 콘크리트 블록의 제조방법, 및 그 옹벽용 콘크리트 블록의 시공방법에 관한 것이다.The present invention relates to a concrete block for a retaining wall, a method of manufacturing the concrete block for the retaining wall, and a construction method of the concrete block for the retaining wall, and more specifically, the front part of the retaining wall block is formed by mixing aggregate and concrete, and the middle part The unit retaining wall block and the rear part form a unit retaining wall block molded of concrete, and the unit retaining wall block is formed integrally with the front part and then cut and polished in half, thereby forming a smoother and more luxurious cross section of the front part. It prevents color deterioration and can be used semi-permanently.When it is manufactured in wet or dry type, the change of the retaining wall block is minimized so that whitening does not occur on the front surface, and the front surface of various colors can be formed by using colored aggregates. Therefore, it relates not only to disaster prevention, but also to a concrete block for a retaining wall that can be well harmonized with the surrounding environment, a method of manufacturing the concrete block for the retaining wall, and a construction method of the concrete block for the retaining wall.

일반적으로, 옹벽(擁壁, retaining wall)이란 토압력(土壓力)에 저항하여 흙이 무너지지 못하게 만든 벽체(壁體)를 말하는 것으로, 지표지반(地表地盤)의 안정된 경사를 그것보다 가파른 경사로 하였을 경우에 일어나는 지반 붕괴를 막기 위해 만든 구조물이다.In general, retaining wall refers to a wall that resists soil pressure and prevents the soil from collapsing. It is a structure made to prevent the collapse of the ground in some cases.

옹벽은 흙을 쌓아 올릴 때, 산을 깎아 낼 때, 해안을 메울 때 등에 필요한 것으로, 옹벽을 시공하는 종류는 블록 조적식 공법으로 오랜 기간 널리 쓰이는 축벽(築壁)이 이것에 속하며, 현재는 콘크리트 블록이 많이 사용된다.Retaining walls are necessary for stacking soil, cutting mountains, and filling the shore. Blocks are used a lot.

또한, 중력식(重力式) 콘크리트 옹벽은 콘크리트 자체의 중량으로 지반의 붕괴를 막아내는 구조로 구성되는데, 비교적 높이가 낮은 경우에 채택된다.In addition, the gravity-type concrete retaining wall is composed of a structure that prevents the collapse of the ground by the weight of the concrete itself, and is adopted when the height is relatively low.

아울러, 특수 철근콘크리트 옹벽은 높이가 커져서 중력식 옹벽으로는 경제적이지 않거나 벽면을 수직으로 하여 용지(用地)의 이용을 유리하게 할 필요가 있는 경우에 이용된다. 이 밖에 강판이나 목책(木柵)을 이용한 간단한 옹벽도 있다.In addition, a special reinforced concrete retaining wall is used when the height is increased and thus it is not economical as a gravity retaining wall, or when it is necessary to make the use of paper advantageous by making the wall surface vertical. In addition, there are simple retaining walls using steel plates or wooden fences.

옹벽은 옹벽 뒤의 지반에 빗물이 침수하여 그 지반을 묽게 하고, 내부에 토사가 유동수와 함께 유동하면서 옹벽에 엄청난 하중이 집중되어 지반을 무너뜨림에 따라 붕괴에 의한 사고가 자주 일어난다.In the retaining wall, rainwater floods the ground behind the retaining wall, thinning the ground, and as the soil flows with the flowing water inside, an enormous load is concentrated on the retaining wall and collapses the ground, causing accidents due to collapse.

일반적으로 사용되는 옹벽블록 시공방법은, 옹벽블록을 교차하도록 형성하고 물이 빠지는 배수를 형성하여 옹벽블록의 결합력을 강화하면서 배수구를 구비하여 내부 물을 외부로 배수함으로써, 견고한 옹벽을 유지하도록 한다.In general, the retaining wall block construction method is formed so as to cross the retaining wall block and formed a drainage through which water is drained, strengthening the bonding force of the retaining wall block, and draining the internal water to the outside by providing a drain hole to maintain a solid retaining wall.

또한, 콘크리트 블록 형태로 형성된 옹벽블록은 비, 바람에 침식되기 쉬운 콘크리트의 특성상 옹벽이 설치되는 외측으로 외장재를 형성하여 콘크리트의 침식을 방지하면서 외관도 미려하게 형성하는 방식을 사용하기도 하나, 본드나 모르타르를 이용하여 외장재를 부착하기 때문에 시간이 흐르면서 외장재의 접착력이 떨어지는 문제가 있고, 이로 인한 유지보수에 많은 인력과 비용이 발생하는 문제가 있다.In addition, the retaining wall block formed in the form of a concrete block uses a method of forming a beautiful exterior while preventing the erosion of concrete by forming an exterior material outside where the retaining wall is installed due to the nature of concrete that is prone to erosion by rain and wind. Since the exterior material is attached using a mortar, there is a problem that the adhesion of the exterior material decreases over time, and there is a problem that a lot of manpower and cost are generated for maintenance and repair.

또한, 종래의 옹벽블록은 형틀(거푸집)에 콘크리트를 타설하고, 그 형틀을 제거한 후 양생하여 제조한다. In addition, the conventional retaining wall block is manufactured by pouring concrete into a mold (form) and curing after removing the mold.

이와 같이 제조된 옹벽블록을 적층 하여 옹벽으로 쌓을 경우에, 옹벽블록들의 전면이 모여 옹벽의 전면을 형성한다. 하지만, 옹벽블록들의 전면은 콘크리트의 색상인 회색을 띠고 있으며, 옹벽 또한 회색을 띤다. When the retaining wall blocks manufactured as described above are stacked to form a retaining wall, the front surfaces of the retaining wall blocks are gathered to form the front surface of the retaining wall. However, the front of the retaining wall blocks is gray, which is the color of concrete, and the retaining wall is also gray.

옹벽은 재해를 예방하는 유용한 시설물이지만, 주변 환경과 조화되지 않는 회색의 옹벽은 외관적인 문제 때문에 혐오시설물로 취급되고 있는바, 이와 같은 옹벽의 문제점을 해결하기 위해서, 형틀에 다양한 문양을 형성하여 옹벽블록의 전면이 단순한 평면이 아닌 다양한 문양을 갖도록 하거나, 또는 옹벽의 전면에 페인트칠을 하거나 그림을 그려 주변 환경과 조화를 이루도록 하고 있다. Retaining walls are useful facilities to prevent disasters, but gray retaining walls that do not harmonize with the surrounding environment are treated as disgusting facilities because of their appearance.To solve the problem of retaining walls, various patterns are formed on the frame to retain walls. The front of the block is designed to have a variety of patterns rather than a simple plane, or paint or draw on the front of the retaining wall to harmonize with the surrounding environment.

하지만, 이와 같이 개선된 옹벽블록이라도 인위적 개선에 불과하여 자연 친화성이 미약하다는 단점이 있다.However, even with such an improved retaining wall block, it is merely an artificial improvement and has a disadvantage in that the nature affinity is weak.
