において矢印は水の流れを示す。As shown in FIG. 2, when the clay 1 having a high water content ratio is put into the water-permeable bag 2, the clay 2 is independent when the bag 2 is independent, that is, in one case. The water inside passes through the water-permeable cloth forming the bag 2 and is discharged to the outside. However, in箇状4, elongated bag 2
In the case of stacking, since the stacked bags 2 are in close contact with each other, the water squeezed from the clay 1 is discharged to the outside through the cross section of the cloth itself forming the bag 2. FIG.
In, the arrow indicates the flow of water.

よって上段の袋が破断するおそれがあった。 However, the cloth forming the bag 2 is thin,
Since the cross-sectional area is small, when the bag 2 is long, there is a risk that the discharged water will be prevented from flowing out quickly, that is, the well resistance will be large, and the sinking due to the discharge of water will be delayed at the center of the bag 2. It was Also, when loading the bags,
The middle part of the bag is shaped between the adjacent ones of the lower bags.
Extremely digging into the space created, to this digging
Therefore, the upper bag may be broken.

The bags are arranged in a row, with the bag 2 between the upper surfaces of the bags adjacent to each other.
The water-permeable layer 3 in the space of the substantially triangular cross section formed along the
To form .

Align them with the permeable layer 3 as the center and arrange them in a line.
The second layer is used as the second stage, and the bags laminated by the above steps are of a predetermined height.
To be repeated in the summary.

未然に防止できる等大きな利益がある。Since the method of the present invention is as described above,
It said permeable layer 3 becomes a drainage layer, because the water from the bag 2 to flow through the permeable layer 3 without passing through the cross section of the fabric itself, when a uniform clay water from the bag can be discharged promptly
In both cases, the upper bag is between the adjacent lower bags.
It is extremely difficult to break into the formed space.
There are great benefits, such as prevention .
