Description of the Related Art Conventionally, as a method of constructing earth retaining material for preventing earth and sand from flowing out from a slope of a mountain forest, or embankment of a revetment of a river embankment, a method of directly hitting a concrete pile on a slope, a concrete secondary product. A method using a concrete block, a method of stacking stones, and the like are known. A construction method using a concrete pile or a construction method using a concrete block is an excellent method that is easy to perform and has sufficient strength, and is widely used in recent years due to a shortage of forest workers and an aging population. However, such an earth retaining method damages the natural scenery because the slope to be earthed and the entire riverbank are covered with concrete. In addition, when the concrete is hit or the concrete block is manufactured and transported, energy is wasted, and the construction cost is high in consideration of the environmental cost.
