  According to the ninth aspect of the present invention, the sandbag box drains water from the earth and sand contained in the box body to the outside of the box body on each surface constituting the box body. It is characterized by the provision of drainage means.

  According to a tenth aspect of the present invention, a sandbag box is characterized in that the drainage means is provided with a mesh material that is easy to permeate moisture and difficult to permeate earth and sand.

  According to the present invention, there is provided a sandbag box that can be reliably stacked in a state in which earth and sand are put therein.

  Moreover, according to this invention, the sandbag box which can be easily carried in the state which accommodated earth and sand is provided.

  Hereinafter, the configuration of a preferred embodiment (first embodiment) of a sandbag box according to the present invention will be described in detail with reference to the accompanying drawings.

  First, as shown in FIG. 1 as a perspective view in a closed state, in FIG. 2 as a perspective view in an open state, and in FIG. 3 as an exploded view thereof, the sandbag box 10 of this first embodiment is a substantially rectangular parallelepiped. The cloth box body 12 is made of a cloth-like body and can contain earth and sand and has an open upper surface, and is integrally connected to the upper surface of the box body 12 at one side edge 14a. 2 is provided so as to be open over substantially the entire surface, and the earth and sand are accommodated in the open state shown in FIG. 2, and the upper surface piece 14 for sealing the earth and sand inside in the closed state shown in FIG. A pair of fasteners 16 as attachment means for releasably attaching 14 to the box body 12 and a pair extending integrally outward from opposite side edges of the surface corresponding to the lower surface piece of the box body 12. With extended pieces 18a, 18b It is configured.

  Here, each surface (both side pieces 20, 22, both side pieces 24, 26, and the bottom piece 28) constituting the box body 12 described above has moisture from the earth and sand contained in the box body 12. Is provided with a mesh material 18 as a drainage means for draining the outside of the box body 12. The mesh material 18 is formed of a material that easily transmits moisture and does not easily transmit soil and sand. The drainage means does not need to be formed on all five surfaces as described above, and may be formed on at least one surface, for example, the lower surface piece 28.

  The fastener 16 described above includes three side edges 14b, 14c, 14d excluding one side edge 14a that is a connection edge of the upper surface piece 14, and three upper edges 20a, 24a, 22a is configured to be releasably connected.

  On the other hand, each of the above-described extending pieces 18a and 18b is formed in a box shape with both ends open, and is set so that a rod-like or pipe-like member can penetrate inside. Since the two extending pieces 18a and 18b are configured in this manner, as shown in FIG. 4, two human hands are used with both the extending pieces 18a and 18b penetrating the rod-like or pipe member 30 respectively. Thus, by grasping both ends of the rod-like or pipe member 30, the heavy sandbag box 10 filled with earth and sand can be reliably moved.

  Further, as shown in FIG. 5, one extension piece 18 a is passed through the rod-shaped or pipe member 30, and the two ends of the rod-shaped or pipe member 30 are respectively carried or lowered by two persons. Thus, the heavy sandbag box 10 filled with earth and sand can be surely moved. As will be described later, when the heavy sandbag box 10 filled with earth and sand is lifted and moved in this manner, the rod-like or pipe member 30 is passed through the extension pieces 18a and 18b and held. Needless to say, the two extending pieces 18a and 18b can be directly gripped by a human hand and can be lifted and moved.

  Here, each extended piece 18a, 18b is cut into two parts by cutting lines 32a, 32b at the center in the longitudinal direction. In other words, each extended piece 18a, 18b is divided into two divided divided pieces 18a1 / 18a2: 18b1 / 18b2 by corresponding cutting lines 32a, 32b. Thus, when the extended pieces 18a and 18b are gripped by a human hand, a state in which one of the extended pieces 18a and 18b is pulled by the handle on the other side and becomes difficult to grip is effectively prevented. It will be.

  On the other hand, the extension pieces 18 a and 18 b described above are set so that their sizes do not exceed the size of the lower surface piece 28 of the box body 12. Specifically, the size of each extension piece 18a, 18b is set to exceed a quarter of the size of the lower face piece 28 of the box body 12. That is, by setting the sizes of the extending pieces 18a and 18b to be sufficiently large as described above, the extending pieces 18a and 18b can be easily gripped manually. As a result, the operator can carry the pair of extending pieces 18a and 18b as both ends of the sandbag in which the sand is contained in the sandbag box 10 while grasping with both hands. The workability is significantly improved as compared with a conventional hemp box containing earth and sand.

  Further, as described above, the fastener 16 is attached along the three side edges 14b, 14c, and 14d of the upper surface piece 14 of the box body 12 described above. As shown in FIG. By opening, the surface corresponding to the upper surface piece 14 of the box body 12 is opened over substantially the entire surface, and the earth and sand can be easily removed through the surface corresponding to the opened upper surface piece 14. 12 can be accommodated.

  In addition, as shown in FIG. 1, the surface corresponding to the upper surface piece 14 of the box body 12 is hermetically sealed by closing the fastener 16 as shown in FIG. 1, and the earth and sand housed in the box body 12. Therefore, the housing state is stably maintained without leaking out. Moreover, the box main body 12 will exhibit a substantially rectangular parallelepiped shape in such a state that earth and sand are fully accommodated therein.

  As a result, as shown in FIG. 6, the sandbag box 10 in which the earth and sand are accommodated can be stacked in a pyramid shape, and can also be stacked in a rectangular parallelepiped shape although not shown. Become. This can bring about remarkable effects in three respects. That is, firstly, in the sandbag box made of a conventional hemp bag, when piled up in a pyramid shape, the piled up state became unstable and was not preferable. By using it, even if it piles up in a pyramid shape, the piled-up state becomes what repeated flat stacking, can be maintained stably, and can maintain a storage state favorably.

  Secondly, when stacking, as shown in FIG. 7, two extension pieces integrally formed so as to protrude laterally around the lower surface piece 14 of the box body 12 of one sandbag box 10X. An adjacent sandbag box 10Y is stacked on one of the protruding pieces 18a and 18b, and is sandwiched between the sandbag box 10Z (the floor or the ground in the case of the lowest level). Become. That is, one sandbag box 10X is locked in place by a sandbag box 10Y next to it and a sandbag box 10Z below the sandbag box 10Y. It will be maintained stably. In addition, the other of the two extended pieces 18a and 18b of one sandbag box 10X is flipped up so as not to interfere with the adjacent sandbag box 10 and is brought into close contact with the side piece 22 of itself. Has been made.

  That is, the two extending pieces 18a and 18b integrally attached to the sandbag box 10 of the first embodiment function as “gripping pieces” when being carried, and when being stacked, , Functioning as "locking piece".

  Thirdly, when the sandbag box 10 of the first embodiment is used, for example, when repairing a breakage point of a dike, the shape of the broken portion is indeterminate, and it can be used for any shape. However, the rectangular parallelepiped shape of the sandbag box 10 according to the first embodiment is not rigid and has considerable flexibility and exhibits adaptability to any shape. It can be done and there is no problem.

  Next, a method for forming the sandbag box 10 having the various features described above will be described below with reference to a development view shown in FIG. In FIG. 3, the broken line indicates a valley line, and the alternate long and short dash line indicates a mountain line.

  As shown in FIG. 3, the development body of the sandbag box 10 is integrally formed with one extending piece 18 a integrally connected to the right side of the lower surface piece 28 in the drawing and the left side of the lower surface piece 28 in the drawing. The other extended piece 18b connected, one horizontal piece 24 integrally connected to the lower side of the lower surface piece 28 in the figure, and the other horizontal piece 26 connected integrally to the upper side in the figure. And. Further, one side piece 20 is integrally connected to the right side of the one extending piece 18a in the drawing, and the other side piece 22 is integrally connected to the left side of the other extending piece 18b in the drawing. Has been. Furthermore, the upper surface piece 14 is integrally connected to the upper side of the other lateral surface piece 26 in the figure.

  Overlapping seams 20x / 20y: 22x / 22y: 24x / 24y: 26x / 26y are integrally connected to both end edges of each side piece 20, 22 and both end edges of each side piece 24, 26. Yes. Then, one overlap seam allowance 20x of one side edge piece 20 and the other overlap seam allowance 24y of one lateral surface piece 24 are overlapped with each other and set so as to be sewn integrally. The other overlap seam allowance 20y of one side edge piece 20 and the one overlap seam allowance 26y of the other lateral surface piece 26 are overlapped with each other and set so as to be sewn together.

  Furthermore, the other overlap seam allowance 22y of the other side edge piece 22 and the one overlap seam allowance 24x of one lateral surface piece 24 are set to overlap each other and sew together. Further, one overlap seam allowance 22X of the other side edge piece 22 and the other overlap seam allowance 24y of the other lateral surface piece 24 are overlapped with each other and set so as to be sewn together.

  In this manner, the side edge pieces 20 and 22 and the side face pieces 24 and 26 are sewn in a state where they are overlapped with each other through the overlap seam allowance, so that the sandbags shown in FIGS. 1 and 2 are used. The box main body 12 of the box 10 is formed in a very strong state, and even if it is filled with earth and sand, there is no risk of tearing.

  Here, before the above-described sewing operation, the extending piece 18a (18b) is bent along the mountain line shown in the figure to achieve a box-like form, and the lower face piece 28 and the side piece 20 (22). Thus, a state of being connected integrally with each other is achieved. In this way, each extending piece 18a, 18b can be penetrated by a rod-like or pipe member 30, and each holding piece 18a, 18b is gripped in a state where the earth and sand are fully filled in the box body 12. However, there is no fear that they will be broken.

  As described above, according to the sandbag box 10 of the first embodiment, the sandbag can be reliably stacked in a state in which the earth and sand are put therein, and can be easily carried in a state in which the earth and sand are accommodated. Will be able to.

  It goes without saying that the present invention is not limited to the configuration of the first embodiment described above, and can be variously modified without departing from the gist of the present invention.
