Abstract

PROBLEM TO BE SOLVED: To make a sandbag which is not likely to move from an installed position by placing a tie on a side and/or a lower end of a bag. SOLUTION: A closing string 2 is provided at an upper end of a bag, while a tie 3 is provided on a side (an end of a side face) and at a lower end of the bag. The tie 3 is fixed by an arbitrary method such as sewing. After soil is put in the bag thus constituted, a mouth of the bag is closed by the closing string 2 to make a sandbag A. When a bank is to be constructed of thus formed sandbags A, the ties 3 or the ties 3 and the closing strings 2 of laterally and vertically adjacent sandbags A are tied with each other to construct the bank. Since an upper end and a lower end of the sandbag A are thus coupled with another sandbag A, the individual sandbags A, especially those on the uppermost stage are extremely unlikely to move. As a result, the bank which is not likely to break can be constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag for sandbags.

[0002]

2. Description of the Related Art A conventional bag for sandbags is provided with a closing cord 2 at an upper end portion of the bag 1 as shown in FIG. 6, and as shown in FIG. After packing, the mouth of the bag was closed with the closing cord 2 to form sandbag A.

[0003] The sandbags A thus produced are stacked as shown in Fig. 8 to construct a dike or the like.

[0004]

However, in the embankment constructed in this manner, sandbags A are merely stacked, and in particular, each sandbag A located at the uppermost stage is easy to move, so that the amount of water is small. When there are many sands, the sandbags A are sequentially washed from the sandbag A located at the uppermost level, and the embankment may be broken.

[0005] An object of the present invention is to provide a bag for sandbags, which can make a sandbag harder to move from a position where it is installed than before.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a bag for sandbags, in which a closing cord is provided at the upper end of the bag, the bag being bound to the side surface and / or the lower end of the bag. A string is provided.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 shows Embodiment 1 of the present invention.
It is a front view which shows the structure of.

In FIG. 1, a closing cord 2 is provided at the upper end of the bag 1 and a tying cord 3 is provided at the side (the end of the side in this embodiment) and the lower end of the bag 1. . In the present embodiment, the tying cord 3 is sewn and fixed to the bag 1, but the tying cord 3 may be fixed in any manner.

In the present embodiment, a biodegradable plastic is used as the material of the bag 1.

In this embodiment constructed as described above, after filling the inside of the bag 1 with the soil and closing the mouth of the bag with the closing cord 2, the sandbag is produced as in the conventional case.

When the embankment is constructed by the sandbags A thus produced, as shown in FIG. 2, the straps 3 of the sandbags A adjacent to each other or the straps 3 and the closing straps 2 are connected to each other. We build dike while linking.

In the bag for sandbags according to the present embodiment, since the binding string 3 is provided not only on the side surface but also on the lower end, not only the sandbag A adjacent in the left-right direction but also
As shown in FIG. 3, sandbags A stacked vertically adjacent to each other can be connected to each other using the tying cord 3.

As shown in FIG. 3, when the embankment is constructed using this embodiment, since the upper end and the lower end of the sandbag A are connected to other sandbags, each sandbag A, particularly The sandbag A in the upper stage becomes significantly harder to move than in the past.
Therefore, when the embankment is constructed using this embodiment, it is possible to construct the embankment which is hardly broken as compared with the related art.

Further, in this embodiment, since the material of the bag 1 is a biodegradable plastic, even if the embankment constructed at the time of the disaster is left for some reason, the bag 1 can be used after a long time. Since only the internal soil remains after being decomposed, the environment is not polluted by the bag 1.

(Embodiment 2) FIG. 4 shows Embodiment 2 of the present invention.
FIG. 2 is a front view showing the configuration of FIG. Reference numeral 4 denotes a sewing thread sewn on the front side (the front side in FIG. 4) and the back side of the bag 1.

As described above, in the present embodiment, the sewing thread 4
Thereby, the width of the central portion inside the bag 1 is smaller than the width of the upper end portion and the lower end portion.

When a sandbag is formed by filling the soil in the present embodiment configured as described above, the amount of soil clogged in the central portion is smaller than that of a conventional sandbag.

Therefore, according to this embodiment, since the central portion of the sandbag A can be easily bent, when the sandbag A is used as the weight of the barricade B as shown in FIG. The sandbag A can be easily attached to the barricade B. Furthermore, the sandbag A can be firmly fixed to the barricade B by tying the closed strap 2 at the upper end of the attached sandbag A, the strap 3 at the lower end, and the strap 3 at the side face.

In the first and second embodiments described above, the material of the bag 1 is made of a biodegradable plastic. However, the material of the bag 1 is not limited to the biodegradable plastic 1, Material may be used.

[0021]

As described above, according to the present invention, it is possible to produce a sandbag which is hard to move from the installed position as compared with the related art.
