Description

옹벽블럭{Retaining wall block}Retaining wall block

본 고안은 옹벽블럭에 관한 것이다.The present invention relates to a retaining wall block.

일반적으로, 비교적 가파른 경사로 이루어진 하안(河岸)이나 해안(海岸) 및 뚝 등을 보호하여 유수에 의한 물가선의 침식을 방지하기 위하여 그 비탈면에는 옹벽블럭을 이용한 옹벽을 시설하고 있으며, 특히 수직경사로 이루어진 도로변의 시공면에는 옹벽블럭을 이용한 수직옹벽이 설치된다.Generally, retaining walls using retaining wall blocks are installed on the slope to prevent erosion of shoreline by flowing water by protecting rivers, coasts, and fortifications with relatively steep slopes. In the construction surface of the vertical retaining wall using a retaining wall block is installed.

이와 같은 옹벽의 시공방법은 예로부터 널리 쓰이는 옹벽블럭을 쌓는 방식이 주류를 이루고 있으며, 근래에는 콘크리트로 된 옹벽블럭으로 옹벽을 형성하고 있다. 콘크리트로 된 옹벽은 콘크리트자체의 중량으로 지반 붕괴를 막아내는 구조의 중력식 콘크리트옹벽과, 옹벽의 높이가 높아져 중력식 옹벽으로는 경제적 가치가 없거나 벽면을 수직으로 하여 용지의 이용을 극대화하는 경우에 사용되는 철근 콘크리트옹벽이 있다.The construction method of such a retaining wall is a main method of stacking retaining wall blocks which are widely used since ancient times, and in recent years, retaining walls are formed of concrete retaining wall blocks. The retaining wall made of concrete is a gravity concrete retaining wall that prevents the ground collapse by the weight of the concrete itself. There is a reinforced concrete retaining wall.

하지만, 기존의 콘크리트로 된 옹벽블럭에 의한 옹벽은 단순히 옹벽블럭을 적층하거나 배열한 후, 인접한 옹벽블럭에 몰타르를 접합하여 옹벽을 형성함에 따라 견고성이 저하되고, 이로 인해 토압력에 의한 형태변형 및 붕괴가 쉽게 발생하는 문제점이 있다.However, the retaining wall by the retaining wall block of the existing concrete simply stacks or arranges the retaining wall block, and then joins the mortar to the adjacent retaining wall block to form the retaining wall, thereby deteriorating the rigidity. There is a problem that collapse easily occurs.

이에, 본 고안은 기존의 옹벽블럭이 갖는 제반적인 문제점을 해결하고자 창안된 것으로,Therefore, the present invention was devised to solve the general problems of the existing retaining wall block.

본 고안이 이루고자 하는 기술적 과제는 상, 하, 좌, 우의 옹벽블럭이 상호 보완기능을 수행토록 하여 옹벽의 시공시 견고성을 향상시킬 수 있는 옹벽블럭을 제공하는데 있다.The technical problem to be achieved by the present invention is to provide a retaining wall block that can improve the robustness of the construction of the retaining wall by allowing the retaining wall blocks of the upper, lower, left and right to complement each other.

본 고안이 이루고자 하는 다른 기술적 과제는 기존의 중력식 콘크리트옹벽과 철근 콘크리트옹벽을 접목시켜서, 견고한 옹벽구조를 구현함에 따라 토압력에 의한 형태변형 및 붕괴를 방지할 수 있는 옹벽블럭을 제공하는데 있다.Another technical problem of the present invention is to combine the existing gravity-type concrete retaining wall and reinforced concrete retaining wall, to provide a retaining wall block that can prevent the deformation and collapse caused by earth pressure by implementing a solid retaining wall structure.
