Description

  The present invention relates to an inflatable sandbag that can be suitably used when, for example, a flood occurs.

  Inflatable sandbags are constructed by storing an inflatable body such as a water-absorbing polymer in a water-permeable bag such as a hemp bag. It is lightweight and compact before use, and is convenient to carry and store. Or by absorbing moisture, it changes into a sandbag capable of blocking water.

  An example of such an expandable sandbag is disclosed in Patent Document 1 below.

  This sandbag uses coconut shell fibers as an expansion body. When a water-absorbing polymer is used as an expanded body, it must be first dried after use and then incinerated as garbage. However, according to the invention of the above-mentioned Patent Document 1, such labor is unnecessary and it is only necessary to embed. That is, it has the advantage that disposal after use is easy.

  However, since the palm shell fiber absorbs water, it is difficult to obtain a large specific gravity even when water is absorbed as compared with the case where a water-absorbing polymer is used. For this reason, since there is a possibility of flowing into the invading water, natural stone is housed in the bag as a weight together with the coconut shell fiber.

  However, since natural stones are stored, the weight and size of the sandbag before use are heavier and larger than sandbags using a water-absorbing polymer.

  In the inflatable sandbags that have been proposed so far, in order to prevent the sandbags from being washed away during use and to reduce the trouble of arranging the sandbags one by one, a hole for connecting other sandbags adjacent to each other is made permeable. There is what was provided in the bag (refer to patent documents 2 and patent documents 3 below).

  However, since these inventions provide holes at the four corners of the water-permeable bag and connect adjacent ones to each other, there is a difficulty that the stacked sandbags cannot be connected. For this reason, there exists a possibility that a clearance gap may be made between sandbags at the time of use.

  In addition, since the hole is formed, there is a disadvantage that it is difficult to deal with in a sudden situation because it requires a relatively troublesome work of passing a string or the like through the hole during use.

  Furthermore, since eyelets (hole metal fittings) are used for forming the holes, there is a problem that the water-permeable bags are easily cut.

  Therefore, the main object of the present invention is to prevent the water from flowing when it absorbs and expands. Another object of the present invention is to make it possible to connect the expandable sandbags that are superposed vertically so as to eliminate gaps between the sandbags in use.

  Accordingly, the present invention provides an inflatable sandbag in which an inflatable body that absorbs liquid and inflates is contained in a square-shaped water-permeable bag. It is an inflatable sandbag provided with connecting means for connecting to another inflatable sandbag that is adjacent and / or superposed on an intermediate portion between two opposite sides.

  Another means is an inflatable sandbag in which an inflatable body that absorbs liquid and inflates is accommodated in a rectangular permeable bag, and has six locations between the four corners of the permeable bag and the middle position of the long side. And an inflatable sandbag provided with connecting means for connecting to another inflatable sandbag adjacent and / or superposed.

  Still another means is to connect the end portions of the four sides or the four corners of the water-permeable bag using a connecting means between adjacent water-permeable bags, and between the water-permeable bags adjacent to each other. It is an inflatable sandbag which couple | bonds a connection means and the connection means of the intermediate part of the said 2 sides in the another water-permeable bag to superpose | polymerize, or the intermediate position of the said long side.

  That is, in use, the inflatable sandbags are connected to each other using a connecting means provided in the water-permeable bag. For example, the connection is made by first connecting the adjacent inflatable sandbags using the connecting means at the ends of the four sides or the four corners of the water-permeable bag and then connecting the adjacent inflatable sandbags. And the connecting means at the intermediate portion of the two sides or the intermediate position of the long side in another inflatable sandbag to be superposed so that the gap between them is filled with each other when the inflatable sandbag expands It is good to carry out alternately.

  When an inflatable sandbag is placed at the entrance to a building or underground passage during a flood, the inflatable sandbag absorbs the invading water and swells to block the water. Moreover, since the inflatable sandbags are connected to each other by the connecting means, they are bulky and heavy, and unlike the case where the inflatable sandbags are lined up one by one, they are not flushed with water.

  In the case where some of the connecting means provided in the water permeable bag are idle, it is preferable to secure the positioning of the inflatable sandbag by tying it to an appropriate structure or the like.

  If the expanding body sucks liquids other than fresh water, for example, seawater or oil, it can be used other than water damage.

  The connecting means may be constituted by a string-like body tied to a water-permeable bag. At the time of connection, it is only necessary to connect a connecting means made of a string-like body, so that the connecting operation can be performed easily and quickly as compared with the case where the string is passed through the hole.

  Moreover, while forming the said water-permeable bag with a hemp bag, a part of the said connection means is comprised with the string-like body tied to a hemp bag, and the other connection means is the texture of the cloth which comprises the hemp bag. It may be configured. That is, at the time of connection, the connecting means made of a string-like body is appropriately connected to a texture (connecting means) at a predetermined position in another expandable sandbag that is adjacent or superposed.

  As described above, according to the present invention, the end portions of the four sides of the water-permeable bag having a rectangular shape and the middle portion of the two opposite sides of the four sides, or the four corners of the water-permeable bag having a rectangular shape, Since connecting means are provided at at least six locations in the middle of the long side, in addition to connecting adjacent inflatable sandbags, inflatable sandbags to be polymerized can also be connected.

  For this reason, since a large number of inflatable sandbags can be integrated three-dimensionally, they can be prevented from being washed away by water.

  Moreover, while connecting the edge part of the said 4 sides or the said four corners of the said water-permeable bag between adjacent water-permeable bags using a connection means, The connection means of this adjacent water-permeable bags, When combined with the intermediate portion of the two sides or the intermediate position of the long side in another water-permeable bag to be polymerized, the adjacent inflatable sandbags to be polymerized are alternately filled so as to fill each other. Since it can be laminated, the gap can be tightly closed and water leakage can be eliminated. In addition, if the inflatable sandbag before expansion is connected in advance, the gap is automatically closed.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a plan view of an inflatable sandbag 11 (hereinafter referred to as sandbag). As shown in this figure, the sandbag 11 is stored in the water-permeable bag having a rectangular water-permeable bag 12 having water permeability. The inflatable body 13 and the string-like bodies 14 as connecting means provided in the water-permeable bag 12 are configured.

  The water-permeable bag 12 is not particularly limited as long as it is a material that allows water to pass through the inside thereof. The hemp bag has good water permeability, and when the expandable sandbags are polymerized, a high frictional resistance acts between them and is difficult to slip.

  The expansion body 13 expands by absorbing moisture, and a known material such as a water absorption polymer is used.

  The said string-like body 14 is couple | bonded with six places of the water-permeable bag 12, and is suitably comprised by the string of a raw material. The six places are the four corners of the rectangular water-permeable bag and the middle position of the long side, and the middle portion of the string-like body 14 in the length direction is coupled to the predetermined position of the water-permeable bag 12. .

  For the connection, the folded portion side of the cord-like body 14 folded in half is passed through the weave of the water-permeable bag 12 as appropriate, and then the looped portion is referred to as the looped tip portion (folded portion) side. This can be done easily by pulling through the opposite end. Moreover, since the string-like body 14 is in a state in which the tip side is divided into two, the string-like bodies 14 can be strongly coupled with each other in a free manner.

  The string-like body 14 may be coupled by another linking method, may be coupled by another means such as sewing, or may be coupled indirectly by sewing or the like with a small piece integrated with the string-shaped body.

  The sandbag 11 configured as described above is used for preventing inundation into a building, a site, or the like, or absorbing residual water on the land or road.

  In use, it is only necessary to place it at the use position, but when it is placed, adjacent sandbags or overlapping sandbags are connected by a string-like body 14 to integrate a plurality of sandbags 11.

  For this reason, when the sandbag expands, it is more integrated and heavier than when sandbags are simply arranged alone or when adjacent sandbags are connected to each other. Can be prevented.

  Since the string-like bodies 14... As connecting means are provided at the six locations, the integration can be performed by staggering one step at a time as shown in FIG. That is, it is used to connect the sandbags 11 adjacent to each other at the same step as the four string-like bodies 14... Used to connect to the string-like body between the sandbags 11.

  For this reason, when the sandbag 11 expand | swells, the clearance gap between the sandbags 11 can be closed automatically (refer FIG. 3), and reliable effects, such as flood prevention, can be anticipated.

  Moreover, if there exists a string-like body 14 which remains even if the sandbags 11 are connected, if it connects with appropriate structures, such as a pile, the said flow prevention effect will be improved further.

  Further, since the connecting means is constituted by the string-like body 14, a fine work for inserting the string as in the case where the connecting means is constituted by a hole is unnecessary, and the connecting work can be performed easily and quickly. In other words, even in the case of drought, it can respond immediately.

  And since the string-like body 14 is directly couple | bonded through the weave of the water-permeable bag 12 which consists of a linen bag, intensity | strength is high compared with the case where a hole is formed using eyelets.

  A plurality of such sandbags 11 may be integrated in advance in preparation for an unexpected disaster. Since it is lightweight, compact and thin, it can be stored compactly, for example, by rolling it even when connected.

In correspondence between the configuration of the present invention and the configuration of the above-described one form
The connecting means of the present invention corresponds to one form of the string-like body 14 and the weave 15,
The present invention is not limited to the configuration of the above-described one form.

  For example, it is not necessary to configure all the connecting means with the string-like body 14. 4 and 5 show an example thereof. In the sandbag 11 of FIG. 4, the connecting means at the four corners are constituted by the string-like bodies 14, and the connecting means at the middle position of the long side is the water-permeable bag 12 made of hemp bags. It is composed of a texture 15 of the constituent fabric. In the sandbag 11 of FIG. 5, conversely, the connecting means at the four corners are constituted by the fabric texture 15, and the connecting means at the middle position of the long side is constituted by the string-like bodies 14, 14.

  In addition, the same code | symbol is attached | subjected about the same part as the said structure, and detailed description is abbreviate | omitted.

  Such a sandbag 11 is connected and integrated as shown in FIG. 6, for example. As shown in FIG. 6A, the sandbag 11 in FIG. 4 uses a string-like body 14 to connect adjacent sandbags 11 in the bottom sandbag 11. In the upper sandbag 11, the string-like body 14 is used for connection between adjacent sandbags 11, and is used for connection to the texture 15 at the middle position of the long side in the lowermost sandbag 11. Similarly, the necessary number of steps are stacked.

  As shown in FIG. 6 (b), the sandbag 11 in FIG. 5 is merely arranged in the lowermost sandbag 11, but the sandbag 11 arranged in the upper stage is a string-like shape at the middle position of the lowermost long side. In the body 14, the four weaves 15 are connected to each other in the adjacent direction and the overlapping direction, and are integrated. Similarly, the necessary number of steps are stacked.

  If comprised in this way, use of the string-like body 14 can be decreased and handling, such as when it is folded, is easy. This is suitable when the sandbag 11 is integrated in advance.

  In addition, the water-permeable bag 12 is not limited to a rectangular one, and may be a square or the like. The specific part such as the vicinity of the formation part may be made of another material.

  Furthermore, there may be more than six connecting means. For example, two connecting means can be provided on all four sides.

  Furthermore, the liquid absorbed by the expanding body may be other than water (fresh water). For example, if it is a material that absorbs seawater, oil, etc., the application can be broadened, and the effects of not being washed away and automatically closing the gap can be widely utilized.
