Description

本発明は、水害防止用の水止フェンスや、災害等の緊急時の貯水袋等として利用可能な水嚢袋及びその使用方法に関する。 The present invention relates to a water bag that can be used as a water stop fence for preventing flood damage, a water storage bag in an emergency such as a disaster, and a method of using the water bag.

従来、水害防止用の止水フェンスには土嚢が用いられていたが、土嚢に土や砂等を詰める作業や、撤去作業には多く労力が必要とされていた。そこで、土嚢の代わりに、これらの作業が比較的容易な水嚢を用いることが提案された。 Conventionally, sandbags have been used for water-stop fences to prevent flood damage, but much labor was required for the work of filling the sandbags with soil, sand, etc., and the work of removing them. Therefore, instead of sandbags, it was proposed to use water bags, which are relatively easy to perform these tasks.

特許文献１には、防水性布又はシートで作った袋に、吸水口、排水口を設け、ポンプ等で水を張り込み使用するものが記載されている。 Patent Document 1 describes a bag made of a waterproof cloth or a sheet, provided with a water absorption port and a drainage port, and used by filling water with a pump or the like.

特許文献２には、硬質合成樹脂製の開口された剛性箱体と、この剛性箱体の中に設置される軟質合成樹脂製の水袋から構成されたものが記載されている。 Patent Document 2 describes a rigid box made of hard synthetic resin and composed of a water bag made of soft synthetic resin installed in the rigid box.

しかしながら、特許文献１に記載された発明のように、ただ単に袋に水を張り込むものでは、袋が潰れ易いという問題がある。また、特許文献２に記載された発明のように硬質材料を用いれば袋の形状を保持することができるが、薄く折り畳むことができないため、保管スペースが大きくなるという問題がある。 However, as in the invention described in Patent Document 1, if the bag is simply filled with water, there is a problem that the bag is easily crushed. Further, although the shape of the bag can be maintained by using a hard material as in the invention described in Patent Document 2, there is a problem that the storage space becomes large because the bag cannot be folded thinly.

さらに、特許文献１に記載された発明において、吸水口等に栓や逆止弁を設ければ、水嚢袋の漏水を防ぐことができるが、コンパクトに折り畳んで保管することが難しくなるという問題もあった。 Further, in the invention described in Patent Document 1, if a stopper or a check valve is provided at the water suction port or the like, water leakage of the water bag can be prevented, but there is a problem that it is difficult to fold it compactly and store it. There was also.

上述した課題に鑑み、本発明の水嚢袋は、軟質合成樹脂製の第１の扁平筒体からなる袋本体と、前記袋本体に溶着され、この袋本体の内部に差し込まれた軟質合成樹脂製の第２の扁平筒体からなる注入体と、を備え、
前記袋本体の上方開口端及び下方開口端は、前記袋本体の一対の側部が前記袋本体の内側に折り込まれた状態でそれぞれ溶着されることにより、前記袋本体の上底及び下底を形成し、前記袋本体の折り込まれた部分の下底のコーナー部は水が入らないように溶着により塞がれており、前記袋本体の内部に注入された水の圧力により前記注入体の差し込み部分の内面が密着して漏水を防止するように構成されたことを特徴とする。 In view of the above-mentioned problems, the water bag of the present invention has a bag body made of a first flat tubular body made of a soft synthetic resin and a soft synthetic resin welded to the bag body and inserted into the bag body. With an injectable body made of a second flat tubular body made of
The upper opening end and the lower opening end of the bag body are welded together with a pair of side portions of the bag body folded inside the bag body, thereby forming an upper bottom and a lower bottom of the bag body. The corners of the lower bottom of the folded portion of the bag body are closed by welding to prevent water from entering the bag body, and the injection body is inserted by the pressure of the water injected into the bag body. It is characterized in that the inner surface of the portion is closely attached to prevent water leakage.

また、本発明の水嚢袋の使用方法は、軟質合成樹脂製の第１の扁平筒体からなる袋本体と、前記袋本体に溶着され、この袋本体の内部に差し込まれた軟質合成樹脂製の第２の扁平筒体からなる注入体と、を備え、前記袋本体の上方開口端及び下方開口端は、前記袋本体の一対の側部が前記袋本体の内側に折り込まれた状態でそれぞれ溶着されることにより、前記袋本体の上底及び下底を形成し、前記袋本体の折り込まれた部分の下底のコーナー部は水が入らないように溶着により塞がれてなる水嚢袋の使用方法であって、
前記注入体の注入口から前記袋本体の内部に水を注入し、注入された水の圧力により前記注入体の差し込み部分の内面を密着させ、前記袋本体の内部に注入された水を抜く時は、前記注入体の注入口から棒状筒体を前記袋本体の内部に挿入し、前記袋本体を押圧することにより前記棒状筒体を介して水を抜くことを特徴とする。 Further, the method of using the water bag of the present invention is to use a bag body made of a first flat tubular body made of a soft synthetic resin and a soft synthetic resin welded to the bag body and inserted into the inside of the bag body. The upper opening end and the lower opening end of the bag body are provided with an injection body made of the second flat tubular body of the bag body, respectively, in a state where a pair of side portions of the bag body are folded inside the bag body. By welding, the upper bottom and lower bottom of the bag body are formed, and the corners of the lower bottom of the folded portion of the bag body are closed by welding so that water does not enter. How to use
When water is injected into the inside of the bag body from the injection port of the injection body, the inner surface of the insertion portion of the injection body is brought into close contact with the pressure of the injected water, and the water injected into the inside of the bag body is drained. Is characterized in that a rod-shaped cylinder is inserted into the bag body from the injection port of the injection body, and water is drained through the rod-shaped cylinder by pressing the bag body.

本発明によれば、水を注入した時に袋が潰れにくく、自立性に優れているので、効率的に水止フェンスを形成することができる。また、本発明によれば、袋本体と一体化された注入体の水圧密着効果で漏水を防止することができる。 According to the present invention, the bag is not easily crushed when water is injected and is excellent in independence, so that a water stop fence can be efficiently formed. Further, according to the present invention, water leakage can be prevented by the hydraulic contact effect of the injection body integrated with the bag body.

さらに、本発明によれば、水嚢袋を構成する袋本体及び注入体がいずれも軟質合成樹脂製であり、これらが溶着により一体化されているので、コンパクトに折り畳んで狭い設置場所であっても多数保管することが可能になり、災害時や緊急時に保管場所から迅速に取り出して運搬し、設置することができる。 Further, according to the present invention, both the bag body and the injection body constituting the water bag are made of soft synthetic resin, and these are integrated by welding, so that they can be folded compactly and placed in a narrow installation space. Can be stored in large numbers, and can be quickly taken out of the storage location, transported, and installed in the event of a disaster or emergency.

本発明の水嚢袋は、水害防止用の止水フェンスとしてだけでなく、災害等の緊急時に貯水袋等として、多目的に使用できるものである。 The water bag of the present invention can be used for multiple purposes not only as a water blocking fence for preventing flood damage but also as a water storage bag or the like in an emergency such as a disaster.

次に、本発明の実施形態における水嚢袋１００を図面に基づいて説明する。先ず、図１に示すように、軟質合成樹脂製（例えば、ポリエチレン製）の第１の扁平筒体からなる袋本体１０を準備する。この袋本体１０は上方開口端１１、下方開口端１２を有し、これを扁平に折り畳んだ状態で一対の側部１３，１３を有している。そして、一対の側部１３，１３は、上下方向の折り目線１４を折り目として袋本体１０の内側に折り込まれる。 Next, the water bag 100 according to the embodiment of the present invention will be described with reference to the drawings. First, as shown in FIG. 1, a bag body 10 made of a first flat tubular body made of a soft synthetic resin (for example, made of polyethylene) is prepared. The bag body 10 has an upper opening end 11 and a lower opening end 12, and has a pair of side portions 13 and 13 in a flatly folded state. Then, the pair of side portions 13, 13 are folded inside the bag body 10 with the crease line 14 in the vertical direction as a crease.

そして、図２及び図３に示すように、袋本体１０の上方開口端１１及び下方開口端１２は、袋本体１０の一対の側部１３，１３（１３ａ，１３ａ）が袋本体１０の内側に折り込まれた状態で、内面がそれぞれ上方溶着部１５ａと下方溶着部１５ｂで溶着（ヒートシール）されることにより、袋本体１０の上底１６及び下底１７を形成する。図２、図３において、１３ａは折り込まれた側部を示している。 Then, as shown in FIGS. 2 and 3, the upper opening end 11 and the lower opening end 12 of the bag body 10 have a pair of side portions 13, 13 (13a, 13a) of the bag body 10 inside the bag body 10. In the folded state, the inner surfaces are welded (heat-sealed) by the upper welding portion 15a and the lower welding portion 15b, respectively, to form the upper bottom 16 and the lower bottom 17 of the bag body 10. In FIGS. 2 and 3, 13a indicates a folded side portion.

また、袋本体１０の折り込まれた部分の下底の三角形状のコーナー部は水が入らないように４箇所のコーナー溶着部１８により塞がれる。コーナー溶着部１８は、折り目線１４から下方溶着部１５ｂに架かるように斜めに形成される。 Further, the triangular corner portion of the lower bottom of the folded portion of the bag body 10 is closed by four corner welding portions 18 to prevent water from entering. The corner welded portion 18 is formed obliquely so as to span the lower welded portion 15b from the crease line 14.

また、注入体２０は、同じく軟質合成樹脂製の第２の扁平筒体からなるものであり、袋本体１０の上方開口端１１から内部に差し込まれる。注入体２０は上方溶着部１５ａにより、上方開口端１１と一緒に袋本体１０に溶着することができる。注入体２０は折り畳み可能な筒体であり、注入口２１と注出口２２を有している。そして、注入体２０の差し込み部分の内面は、袋本体１０の内部に注入された水の圧力により密着して漏水を防止するように構成されている。 Further, the injection body 20 is made of a second flat tubular body also made of a soft synthetic resin, and is inserted into the inside from the upper opening end 11 of the bag body 10. The injection body 20 can be welded to the bag body 10 together with the upper opening end 11 by the upper welding portion 15a. The injection body 20 is a foldable cylinder and has an injection port 21 and an injection port 22. The inner surface of the insertion portion of the injection body 20 is configured to be brought into close contact with the pressure of the water injected into the bag body 10 to prevent water leakage.

この水嚢袋１００は、水害防止用の水止フェンスや、災害等の緊急時の貯水袋等としても利用可能であるが、貯水袋として利用する場合は、注入口２１からごみ等が入るのを防ぐために、注入口２１を開閉可能にするファスナー２３（もしくはチャック）を設けるこが好ましい。 The water bag 100 can also be used as a water stop fence for preventing flood damage, a water storage bag in an emergency such as a disaster, etc., but when used as a water storage bag, dust or the like enters from the injection port 21. It is preferable to provide a fastener 23 (or a chuck) that allows the injection port 21 to be opened and closed.

図４に示すように、この水嚢袋１００に注入体２０を介して水を張ると、第１に、袋本体１０の下底１７は、コーナー溶着部１８を設けたことによって角底状に折り畳まれる。 As shown in FIG. 4, when water is filled in the water bag 100 via the injection body 20, first, the lower bottom 17 of the bag body 10 is formed into a square bottom shape by providing the corner welding portion 18. It can be folded.

また、第２に、一対の側部１３，１３（１３ａ，１３ａ）が袋本体１０の内側に折り込まれていることにより剛性が高まる。これらの構成の相乗効果として、袋本体１０は潰れにくく、自立性に優れたものになるので、少ない個数でも効率的に水止フェンスを形成することができる。 Secondly, the pair of side portions 13, 13 (13a, 13a) are folded inside the bag body 10, so that the rigidity is increased. As a synergistic effect of these configurations, the bag body 10 is not easily crushed and has excellent independence, so that a water stop fence can be efficiently formed even with a small number of bags.

また、図５に示すように、水嚢袋１００が横転したとしても、注入体２０の差し込み部分の内面は、袋本体１０の内部に注入された水２００の圧力により密着するので、漏水が防止される。 Further, as shown in FIG. 5, even if the water bag 100 rolls over, the inner surface of the insertion portion of the injection body 20 is brought into close contact with the pressure of the water 200 injected into the bag body 10 to prevent water leakage. Will be done.

また、図４に示すように、水嚢袋１００が自立しており、注入体２０が水２００に漬かってない状態であっても、一旦水を通したことにより注入体２０の差し込み部分の内面は濡れ、水の表面張力により密着状態になるので、外部の衝撃等により水２００が暴れても、注入体２０から水が漏出することない。 Further, as shown in FIG. 4, even when the water sac bag 100 is self-supporting and the injection body 20 is not immersed in the water 200, the inner surface of the insertion portion of the injection body 20 is once passed through the water. Is wet and comes into close contact with the surface tension of water, so that even if the water 200 goes wild due to an external impact or the like, the water does not leak from the injector 20.

これから分かるように、袋本体１０の内部に注入された水２００を抜くのは、押圧しただけでは困難である。そこで、図６に示すように、棒状筒体３０を注入体２０の注入口２１から袋本体１０の内部に挿入し、袋本体１０を外部から押圧することにより、この棒状筒体３０を介して、その出入口３１から水２００を簡単に抜き、再利用することができる。 As can be seen, it is difficult to remove the water 200 injected into the bag body 10 only by pressing it. Therefore, as shown in FIG. 6, the rod-shaped cylinder 30 is inserted into the bag body 10 from the injection port 21 of the injection body 20, and the bag body 10 is pressed from the outside, thereby passing through the rod-shaped cylinder 30. , Water 200 can be easily drained from the doorway 31 and reused.

また、棒状筒体３０の代わりに、弾性を有する薄板体（例えば、硬質合成樹脂製のシート）を注入体２０の注入口２１から袋本体１０の内部に丸めて挿入してもよい。これにより、薄板体は注入体２０の内面に密着して筒状に弾性変形するので、同様な効果を奏する。 Further, instead of the rod-shaped tubular body 30, an elastic thin plate body (for example, a sheet made of a hard synthetic resin) may be rolled into the inside of the bag body 10 from the injection port 21 of the injection body 20 and inserted. As a result, the thin plate body comes into close contact with the inner surface of the injection body 20 and elastically deforms into a tubular shape, so that the same effect can be obtained.

また、薄板体は棒状筒体３０と比べると、丸める前は薄くなっているので、保管／収納スペースを少なくすることができる。この棒状筒体３０若しくは薄板体は、袋本体１０の内部に水２００を注入する時にも使用することができる。 Further, since the thin plate body is thinner than the rod-shaped tubular body 30 before being rolled, the storage / storage space can be reduced. The rod-shaped cylinder 30 or the thin plate can also be used when water 200 is injected into the bag body 10.

次に、水嚢袋１００の幾つかの変形例を説明する。第１の変形例は、図７に示すように、注入体２０は、袋本体１０の折り込み部の上方開口端１１から内部に差し込まれたものである。第１の変形例は図８に示すように、注入体２０は、袋本体１０の折り込まれた側部１３ａから内部に差し込まれたものである。このように、注入体２０の位置は、適宜変更することができる。 Next, some modifications of the water bag 100 will be described. In the first modification, as shown in FIG. 7, the injection body 20 is inserted into the inside from the upper opening end 11 of the folded portion of the bag body 10. As shown in FIG. 8, the first modification is the injection body 20 inserted into the bag body 10 from the folded side portion 13a. In this way, the position of the injector 20 can be changed as appropriate.

次に、水嚢袋１００の幾つかの水止めフェンス用の設置例を説明する。第１の設置例は、図９に示すように、家屋の玄関ドア４０の前に樹脂等からなるシート５０をＬ字状に敷き、このシート５０上に水嚢袋１００を並設したものである。図９（ａ）は水止めフェンスの正面図、図９（ｂ）はその右側面図である。 Next, an installation example for some water stop fences of the water bag 100 will be described. In the first installation example, as shown in FIG. 9, a sheet 50 made of resin or the like is laid in an L shape in front of the entrance door 40 of the house, and the water bag 100 is arranged side by side on the sheet 50. is there. FIG. 9A is a front view of the water stop fence, and FIG. 9B is a right side view thereof.

第２の設置例は、図１０に示すように、家屋や駅入口に設けられた門柱６０，６０の間に複数列に水嚢袋１００を並設し、水止め効果を高めたものである。この場合は、図示しないシート５０を各列の間に介設することにより、さらに水止め効果を高めることができる。 In the second installation example, as shown in FIG. 10, water bag bags 100 are arranged in a plurality of rows between the gate pillars 60 and 60 provided at the entrance of a house or a station to enhance the water stopping effect. .. In this case, the water blocking effect can be further enhanced by interposing a sheet 50 (not shown) between the rows.

次に、水嚢袋１００の第３変形例を図１１に基づいて説明する。この水嚢袋１００では、袋本体１０に取手用又は連結用の貫通穴１９が袋本体１０の上方溶着部１５ａの下に設けられている。水嚢袋１００を運搬する際には、この貫通穴１９に指を差し込むことにより、容易に持ち上げることができる。袋本体１０が破れるのを防止するために、貫通穴１９は袋本体１０の折り込み部に設けることが好ましい。貫通穴１９の個数は適宜変更することができる。 Next, a third modification of the water bag 100 will be described with reference to FIG. In the water bag 100, a through hole 19 for a handle or a connection is provided in the bag body 10 under the upper welding portion 15a of the bag body 10. When transporting the water bag 100, it can be easily lifted by inserting a finger into the through hole 19. In order to prevent the bag body 10 from being torn, it is preferable that the through hole 19 is provided in the folded portion of the bag body 10. The number of through holes 19 can be changed as appropriate.

また、このように貫通穴１９を設けた袋本体１０を補強するために、貫通穴１９の下方の袋本体１０の内面が、補強用溶着部１５ｃにより溶着されていることが好ましい。この場合、貫通穴１９は上方溶着部１５ａと補強用溶着部１５ｃの間に設けられる。 Further, in order to reinforce the bag body 10 provided with the through hole 19 in this way, it is preferable that the inner surface of the bag body 10 below the through hole 19 is welded by the reinforcing welding portion 15c. In this case, the through hole 19 is provided between the upper welding portion 15a and the reinforcing welding portion 15c.

図１２は、このような貫通孔付きの水嚢袋１００の第３設置例を示す図である。図示のように、隣接する水嚢袋１００は、それぞれの貫通穴１９を通した紐体７０により相互に連結されることにより、水止フェンスの補強がなされている。 FIG. 12 is a diagram showing a third installation example of the water bag 100 having such a through hole. As shown in the figure, the adjacent water bag 100s are connected to each other by a string body 70 through the respective through holes 19 to reinforce the water stop fence.
