Description

  The present invention relates to a form for constructing a frame for stabilizing a slope such as a slope.

  One method of stabilizing the cut slope or natural slope is a free frame construction method. In the free frame method, for example, side frames made of wire mesh are arranged facing each other with a gap between them, and a mortar or concrete is sprayed onto a frame for building a frame that is connected by a connecting material. It is a method of making a continuous frame on sloping ground as a burying frame. According to this free frame construction method, workability is good because it uses a deformable and lightweight wire mesh, and the formwork for constructing the frame is buried, so there is no need for dismantling work. Since mortar or concrete is sprayed, the natural ground and the frame for building a frame are integrated, and a sufficient strength can be obtained.
