で、盛土の安定性が増大する。Fig. 5 shows a cross-sectional view of the road (9) constructed by embankment. First, the earth retaining wall (5) is built on the ground (4) and then the soil is embanked to make the upper surface flat, and the first stage Lay the frame material (1), embed it in the cells of each frame material (1), flatten it by rolling and then build the second frame material (1) on the rolling surface The sloping sloping surface is constructed by offsetting the slope to match the slope of the sloping surface, repeating the desired number of steps for embankment in each cell and rolling.
Embankment while forming (7). Since the frame material (1) shown in Fig. 4 was used for this embankment, the connection base material (2b) functions as a retaining wall and the base material (2a) is laid so as to function as a tensile material. Then, since the embankment (6) has a reinforced soil structure, the stability of the embankment increases.

るという効果を奏する。According to the present invention, a frame material configured so that polygonal cells are continuously formed when a paper, a non-woven fabric or a cloth is stuck and extended is laid on a ground to be filled, and each cell of the frame material is laid. It is a embankment method that repeats the desired number of steps by embedding to fill the inside and rolling and then laying the next stage frame material on the rolling surface and embanking and rolling. Since a lightweight base material such as paper, non-woven fabric or cloth is used as the material for the frame material to be constructed, the frame material is strong even though it is lightweight, which means that it does not take time for transportation or construction on site. Of course, even if the ground material is embedded in each layer of the embankment and the ground is soft, no ground subsidence or displacement occurs, so that the stabilization of the embankment is significantly increased.
