Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a panel soil and a method of manufacturing the same, and more particularly, to a panel soil which prevents flooding of a certain area during floods and the like, and a method of manufacturing the same.

  In the past, in order to prevent flooding to a certain area at the time of flood etc., there are cases where soil banks are piled up to construct a waterproof dike. Since the soil bag used at this time is 16 to 20 kg per one, making the soil bag itself requires a great deal of effort, and accumulating the soil bag is also a very labor-intensive action. Therefore, some proposals have been made.

  For example, as a first proposal, one in which the content of a soil bag is a water-absorbing polymer has been proposed (see, for example, Patent Document 1). According to this, since the usual contents are relatively light as compared with sandbags, the installation of dirtbags becomes relatively easy.

  As a second proposal, a plate-like water blocking panel made of ABS (Acrylonitrile Butadiene Styrene) has also been proposed. According to this, since the storage property is good and the installation can be performed by placing the panel, the installation process can be relatively reduced.

JP 2002-266330 A

  However, the first proposed water absorbing polymer soil bag has a poor storage property due to the nature of the water absorbing polymer, and is fundamentally as a soil bag that may not be usable already when it is used in a long preservation state. There's a problem.

  The second proposal, ABS plate-like water blocking panel, is lighter than general soil, but the weight of the panel itself is relatively heavy, and the installation process can be reduced, but labor for installation It can not be said that the

  The present invention has been made in view of these points, and it is an object of the present invention to provide a panel soil bag which is excellent in storage stability and light weight and thus requires extremely little installation work.

  In the present invention, in order to solve the above problems, in a panel soil bag for preventing flooding to a certain area at the time of flood etc., a horizontal part extended in the opposite direction to the certain area and the certain part of the horizontal part And a vertical portion extending in a vertical direction from the region side end, the horizontal portion and the vertical portion being a waterproof material having a hollow portion communicating in the extending direction, the hollow portion A panel soil bag is provided which is in communication with the end in the extending direction of the horizontal portion and the end in the extending direction of the vertical portion.

  Further, according to the present invention, in the method of manufacturing a panel soil bag for preventing flooding to a certain area at the time of flood etc., a horizontal part extended in the opposite direction to the certain area and the certain area side of the horizontal part And a vertical portion extending in a vertical direction from an end, the horizontal portion and the vertical portion being a waterproof material having a hollow portion communicating with the extending direction, the hollow portion being The horizontal portion and the vertical portion are communicated with each other from the end portion in the extension direction of the horizontal portion to the end portion in the extension direction of the vertical portion. The horizontal portion and the vertical portion are formed by bending a single plate material. There is provided a method of manufacturing a panel soil bag characterized in that the bending process is performed after being cut into a V shape from the bending direction.

  According to the panel soil bag of the present invention, since the hollow portion communicates from the extending direction side end of the horizontal portion to the extending direction side end of the vertical portion, when water is flooded, the hollow portion of the horizontal portion to the vertical portion When air is released in the hollow portion direction, water enters the hollow portion in the horizontal portion and the vertical portion. Therefore, air can be accumulated in the hollow portion to generate buoyancy, and floating or positional deviation due to floating can be prevented. Furthermore, since a relatively light and durable material having a hollow portion can be used, the storage property is good and the installation weight can be remarkably reduced because of its light weight.

  Further, according to the method for manufacturing a panel soil bag of the present invention, since the horizontal portion and the vertical portion are formed by performing the bending process after cutting in a V shape from the bending direction, the horizontal portion can be extended relatively easily. It becomes possible to manufacture the panel soil bag which the hollow part connected from the installation direction side edge part to the extension direction side edge part of the perpendicular | vertical part.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a panel soil bag according to the present embodiment.
As shown in FIG. 1, the panel soil bag 100 is configured by bonding a surface material 110 and a back material 120. The panel soil bag 100 is composed of a vertical portion 101 and a horizontal portion 102.

  Based on the overlapping condition of the surface material 110 and the backing material 120, the central part 130 where the surface material 110 and the backing material 120 overlap, the back material 120 except that the surface material 110 overlaps only a part of the upper end of the vertical part 101 An overlap receiving portion 140 consisting only of the above and an overlapping portion 150 consisting only of the surface material 110 are formed.

In the central portion 130, a stainless steel plate 160 is attached to the end of the horizontal portion 102. Further, a connecting frame 171 is provided on the side of the overlap receiving portion 140 of the end portion of the horizontal portion 102. The connection frame 171 is provided to rotate.
Hereinafter, each member will be described in detail.

FIG. 2 is a front view of the panel soil bag according to the present embodiment.
As shown in FIG. 2, in the overlap receiving portion 140 of the vertical portion 101, a key portion 141 is provided at the upper portion of the surface material 110. The connection frame 172 is provided at the upper end of the central portion 130 of the vertical portion 101, and is rotatably attached so as to cover the key portion 141.

  In the overlapping portion 150 of the vertical portion 101, a key receiving portion 151 is provided at an upper portion of the surface material 110.

When connecting the panel soil bag 100, the overlapping portion 150 is overlapped so as to be on the overlapping receiving portion 140. At this time, the connection is strengthened by hooking the key portion 141 and the key receiving portion 151, and the connection is further strengthened by closing the connection frame 172.
At this time, a gap is provided between the key portion 141 and the key receiving portion 151 so that they can be fitted. Thereby, it becomes possible to bend and install the joint part of panel soil 100 100 according to the curve of the place where soil bag is installed.

FIG. 3 is a top view of the panel soil bag according to the present embodiment.
As shown in FIG. 3, a stainless steel plate 160 is attached to the end of the central portion 130 in the horizontal portion 102. It is for preventing rolling.

  The overlap receiving portion 140 in the horizontal portion 102 has a portion in which the surface material 110 partially overlaps the backing material 120. A key portion 142 is formed at this overlapping portion. Further, in the overlapping portion 150 in the horizontal portion 102, a key receiving portion 152 is provided on the end side of the surface material 110.

  When the panel soil 100 is connected, the overlapping portion 150 and the overlapping receiving portion 140 are overlapped and connected, as in the case of the vertical portion 101, so that the hook portion 142 and the hook receiving portion 152 are fitted. Ru.

  When the key portion 142 and the key receiving portion 152 are fitted, the connecting frame 172 is pivoted so as to cover the fitting portion. This makes the connection strong. Also, a certain clearance is provided for the fitting between the key portion 142 and the key receiving portion 152, and it is possible to bend and install the joint portion of the panel soil 100 in accordance with the bending of the place where the soil is installed. Become.

FIG. 4 is an enlarged cross-sectional view of the junction between the vertical portion and the horizontal portion.
As shown in FIG. 4A, the space between the vertical portion 101 and the horizontal portion 102 of the panel soil 100 penetrates. The panel soil gauze according to the present embodiment is made of plastic corrugated cardboard, and the plastic corrugated cardboard material is subjected to heat bending processing when making the panel soil gauze, but when heat bending processing is performed according to the usual method, The bent portion collapses, and the space of the vertical portion 101 and the space of the horizontal portion 102 are isolated.

  Thus, when the space of the vertical part 101 and the space of the horizontal part 102 are separated, when water is pressed to the panel soil 100, the water enters the space of the horizontal part 102, but the horizontal part 101 and the horizontal The partition wall 103 between the portions 102 prevents the water from rising in the vertical direction. Water may not well enter the horizontal part 102 because there is no way for air to escape.

  As described above, when water does not enter the vertical portion 101 or the horizontal portion 102, the plastic cardboard panel soil bag 100 generates buoyancy with respect to water and significantly impairs its function as a soil bag.

  Therefore, the space of the vertical portion 101 and the space of the horizontal portion 102 are communicated by performing a special heat bending process so that the partition wall 103 is not formed between the vertical portion 101 and the horizontal portion 102. Thus, the water can easily enter the horizontal portion 102, and the water can also rise to the vertical portion 101. Since this does not generate buoyancy to water, it does not impair the function as a dirtbag.

FIG. 5 is a view showing a thermal bending process according to the present embodiment.
As shown in FIG. 5A, in the plastic cardboard material 104 before bending, processing is performed in which a notch 105 is inserted in advance in the bent portion. As shown in FIGS. 5 (B) and 5 (C), the portion of the notch 105 is subjected to the thermal bending process by placing a heated substantially perpendicular jig 200 in the same manner as the ordinary thermal bending process. As described above, by providing the notches 105 and performing thermal bending, formation of the partition 103 shown in FIG. 4B can be prevented, and the hollow portion of the vertical portion 101 can be prevented. And the hollow portion of the horizontal portion 102 communicate with each other.

  By doing this, it is possible to take advantage of the advantages of a hollow material such as plastic cardboard, that is lightweight but durable, in the panel soil. That is, the storage property is good, and since it is lightweight, the process of making the soil bag is unnecessary, the installation process can be reduced, and the installation labor can be remarkably reduced. Furthermore, there is no need for a metal mold as in the case of manufacturing panels made of ABS, and there is no problem that the cost is very high when producing products in small lots.

FIG. 6 is a rear view of the panel soil bag according to the present embodiment.
As shown in FIG. 6, a sealing material 180 is attached to the back surface of the overlapping portion 150. The seal material 180 is, for example, a foam rubber seal material. Thereby, when the overlapping part 150 is overlapped with the overlapping receiving part 140, the leak of water can be prevented.

FIG. 7 is a bottom view of the panel soil bag according to the present embodiment.
As shown in FIG. 7, a sealing material 180 is attached also to the end portion of the bottom surface extending from the center portion 130 to the overlap receiving portion 140 and the width direction side end portion of the center portion 130 and the overlap receiving portion 140. In addition, a sealing material 180 is attached to the back of the overlapping portion 150 as well.

  Further, a rubber plate 190 is attached to the central portion in the width direction from the central portion 130 to the overlap receiving portion 140. The rubber plate 190 functions as a non-slip, and can prevent misalignment when the panel soil 100 is installed.
