The net 7 is led out from the flat bar 8 to the rear. The net 7 is formed by braiding a stranded wire of a synthetic resin fiber having a large tensile strength. It should be noted that the nets 7 arranged side by side in the left-right direction are connected using a connecting tool (not shown).

Next, an example of an embankment construction procedure using the embankment frame A will be described with reference to FIG. In addition, the required number of girder members 1, crosspieces 2, supporting rods 3, flat bars 8, nets 7, and the like are carried into the embankment construction site in a state where they are not assembled together. The embankment construction site is previously leveled so as to have a flat soil surface G1.

After the lowermost girder 1 is installed on the leveled soil surface G1, the lowermost connecting rod 4 and the crosspiece 2 are arranged, so that the crosspiece 2 is connected via the connecting rod 4. It is pivotably supported on the material 1. Then, the support rod 3 is arranged to determine the rising angle of the cross member 2 with respect to the girder 1, the lowermost net 7 is led out behind the girder 1 using the flat bar 8, Is piled up on the soil surface G1 on which is laid, and the net 7, the support rod 3, and the girder 1 are buried. At this time, the soil is compacted appropriately during the charging of the soil.
Then, the level of the upper surface of the piled soil is adjusted to the vicinity of the upper end of the crosspiece member 2 at the bottom.

The girder 1 and the net 7 are arranged on the soil surface of the first-stage pile thus formed in the same manner as described above, and the beam 2 is connected to the girder 1 via the connecting rod 4.
And the support rod 3 determines the rising angle of the crosspiece 2. At this time, the connecting member 5 is used to connect the lower bar member 2 and the upper bar member 2. Thereafter, the soil is piled up and the piled soil is compacted. After that,
The same operation is repeated to construct an embankment of a predetermined height.

In the embankment constructed as described above, the weight of the stacked soil of each step is added to the girder members 1... Of each step, and the soil of the stacked soil of each step forms the mesh of the net 7 of each step. The girder 1 and the net 7 are firmly integrated with the embankment by being buried, and the slope S of the embankment G is pressed down by the bar members 2 of each step, and the embankment G slides down. Against the girder members 1 and against the overhang of the slope S due to the sliding down of the embankment G, the cross members 2. You.
