옹벽용 보강재의 고정방법{Structure of reinforced for retainaing wall}Fixing method of retaining material for retaining wall {Structure of reinforced for retainaing wall}

본 발명은 옹벽의 내부에서 지반 붕괴를 방지하는 옹벽용 보강재의 고정방법에 관한 것으로서, 특히 옹벽 내에 인입되어 토압력에 의해 옹벽을 지지하는 보강재 및 고정보강재를 고정판과 고정캡으로 각각 고정하여 옹벽의 설치를 용이하게 하면서도 견고한 구조를 가지는 옹벽용 보강재의 고정방법에 관한 것이다.The present invention relates to a method for fixing a retaining wall reinforcement to prevent ground collapse inside the retaining wall, and in particular, a reinforcing member and a high information steel which are introduced into the retaining wall to support the retaining wall by earth pressure, respectively, are fixed by a fixing plate and a fixing cap, respectively. The present invention relates to a method for fixing a retaining wall reinforcement having a rigid structure while facilitating installation.

일반적으로 옹벽은 토압력에 저항하여 토사의 무너짐을 방지하는 벽체로써, 지표지반의 비탈면으로부터 발생하게 되는 외력에 의한 지반 붕괴를 막기 위한 구조물이다.In general, the retaining wall is a wall that prevents soil from collapsing by resisting soil pressure, and is a structure for preventing ground collapse due to external force generated from the slope of the ground surface.

상기 옹벽의 형태는 내부에 단계별로 다수의 블록이 적층되고 상기 블록에 보강재의 일측을 안착함과 동시에 타측의 보강재를 절토면 측으로 수평방향으로 연장시켜 매립하는 형태로 이루어져 옹벽 내에 매립된 보강재는 옹벽의 내부에 지지되어 자갈 및 흙과 같은 채움재의 토압력에 의해 그 위치가 고정되므로 블록들로 축조된 옹벽을 절토면측으로 인장하게 되어 측방 토압에 의한 옹벽의 전도를 방지할 수 있도록 구성된 것이다.The retaining wall has a shape in which a plurality of blocks are stacked in stages therein, and one side of the reinforcement is seated on the block, and at the same time, the reinforcing material embedded in the retaining wall extends horizontally to the cut surface side and is embedded in the retaining wall. Since the position is fixed by the earth pressure of the filling material such as gravel and soil, the retaining wall constructed with blocks is tensioned to the cut surface side to prevent the fall of the retaining wall by lateral earth pressure.

상기 보강재는 통상 폴리에스테르 섬유를 이용하여 격자형태로 제직 또는 배열되는 형태로 구성되며 이러한 보강재는 옹벽에 인입될 때 보강재가 길이방향으로 다수 연장되어 옹벽 내부에 설치되는데 다수 연장되는 보강재는 보통 보강재의 단부를 상호 용착 또는 접착하여 연결하여 설치된다.The reinforcement is usually constructed in the form of weaving or arranging in the form of a grid using polyester fibers, such a reinforcement is installed in the retaining wall is a plurality of reinforcement is extended in the longitudinal direction when the reinforcement is drawn into the retaining wall is usually of the reinforcement The ends are welded or glued together.
