Description

本発明は、工場内等に設置されている鋼製配管から漏水した際の応急対策として行う簡易止水方法および簡易止水治具に関するものである。   The present invention relates to a simple water stop method and a simple water stop jig that are used as an emergency measure when water leaks from a steel pipe installed in a factory or the like.

これまで、工場内に設置されている鋼製の水配管（以下、単に配管ともいう）が腐食等のために漏水を発生させると、その配管の止水弁を閉止し、配管内の水を抜き、配管の漏水部（破孔部）を溶接し、その上にバンドを巻いて止水を行っていた（例えば、特許文献１参照）。   Until now, if a steel water pipe installed in the factory (hereinafter also referred to simply as a pipe) causes water leakage due to corrosion, the water shut-off valve of the pipe is closed and the water in the pipe is drained. The water leakage part (break hole part) of piping was welded, the band was wound on it, and the water stop was performed (for example, refer patent document 1).

特開２０００−０８８１７８号公報JP 2000-088178 A

しかし、上記の止水方法では、配管内の水抜きに長時間を要し、その間工場生産が停止していた。特に３００Ａ以上の大径配管の場合、配管内の容積が大きいため、配管内の水抜きに非常に時間が掛かってしまっていた。   However, in the above water stop method, it took a long time to drain the water in the pipe, and the factory production was stopped during that time. In particular, in the case of a large-diameter pipe of 300A or more, since the volume in the pipe is large, it takes much time to drain the water in the pipe.

本発明は、上記のような事情に鑑みてなされたものであり、工場内等に設置されている鋼製配管から漏水した際に、短時間で応急処置をすることができる簡易止水方法および簡易止水治具を提供することを目的とするものである。   The present invention has been made in view of the circumstances as described above, and a simple water stopping method capable of performing an emergency treatment in a short time when water leaks from a steel pipe installed in a factory or the like. It aims at providing a simple water stop jig | tool.

本発明の一実施形態を図面に基づいて説明する。   An embodiment of the present invention will be described with reference to the drawings.

本発明の一実施形態においては、配管内の容積が大きいため、配管内の水抜きに非常に時間が掛かってしまう３００Ａ以上の配管（鋼製配管）を対象にして、その漏水部（破孔部）にシートを貼付して簡易的に止水するようにしている。   In one embodiment of the present invention, since the volume in the pipe is large, the water leakage part (breakage hole) is targeted for a pipe (steel pipe) of 300A or more that takes a very long time to drain water in the pipe. The water is simply stopped by attaching a sheet to the part.

その際に、シートは破孔部の曲面形状に沿って覆うため、破孔部の曲面形状への馴染性と、漏水の水圧に負けて裂けないような強度とを有していることが必要である。ちなみに、漏水による負荷荷重は、水圧としては約５ｋｇ／ｃｍ２の場合、φ４０ｍｍの破孔で約６５ｋｇになる。 At that time, since the sheet covers along the curved surface shape of the pierced hole portion, it is necessary to have a conformability to the curved surface shape of the pierced hole portion and a strength that does not tear against the water pressure of the leaked water. It is. Incidentally, when the water pressure is about 5 kg / cm 2 , the load due to water leakage is about 65 kg with a φ40 mm broken hole.

そこで、破孔部を覆うシートには、厚さが３ｍｍ〜５ｍｍで、破孔部形状への馴染性に優れ、５ｋｇ／ｃｍ２の水圧に耐えうる引き裂き強度を保有したゴムシートを用いる。 Therefore, a rubber sheet having a thickness of 3 mm to 5 mm, excellent in conformity to the shape of the hole, and possessing a tear strength that can withstand a water pressure of 5 kg / cm 2 is used as the sheet covering the hole.

ここで、ゴムシートとしては、ゴムシートの例示：シリコーンゴム、クロロプレーンゴム（ＣＲ）、ウレタンゴム（Ｕ）、ニトリルブタジエンゴム（ＮＢＲ）、エチレンプロピレンゴム（ＥＰＤＭ）、アクリルゴム（ＡＣＭ）、ブチルゴム（ＩＩＲ） 等を用いることができる。   Here, examples of the rubber sheet include rubber sheets: silicone rubber, chloroprene rubber (CR), urethane rubber (U), nitrile butadiene rubber (NBR), ethylene propylene rubber (EPDM), acrylic rubber (ACM), and butyl rubber. (IIR) or the like can be used.

そして、このゴムシートを当該配管に密着固定するには、破孔部から漏水している状態で簡易に止水処置が可能なように、水中でも機能を発揮することができる永久磁石を用いる。その永久磁石には人力で着脱が容易で、かつ水圧に負けないような高磁力を確保できるネオジウム磁石（Ｎｂ−Ｆｅ−Ｂ系磁石）が好適である。   In order to tightly fix the rubber sheet to the pipe, a permanent magnet that can function even in water is used so that the water can be easily stopped in a state where water leaks from the hole. As the permanent magnet, a neodymium magnet (Nb-Fe-B magnet) that can be easily attached and detached by human power and can secure a high magnetic force that does not lose water pressure is suitable.

また、永久磁石は、作業する場所のスペース、破孔した配管の大きさ、破孔の大きさ等に応じて、個数を増減ができるとともに、扱い易いサイズにしている。例えば、１個が□５０ｍｍ×１２．７ｍｍ厚の大きさである。   In addition, the number of permanent magnets can be increased or decreased according to the space at which the work is performed, the size of the broken pipe, the size of the broken hole, and the like, and the permanent magnet has a size that is easy to handle. For example, one piece has a size of □ 50 mm × 12.7 mm.

上記のような考え方に基づき、この実施形態において用いる簡易止水シート（簡易止水治具）を図１、図２に示す。図１は平面図であり、図２は断面図である。   Based on the above concept, the simple water stop sheet | seat (simple water stop jig | tool) used in this embodiment is shown in FIG. 1, FIG. 1 is a plan view, and FIG. 2 is a cross-sectional view.

図１、図２に示すように、この実施形態において用いる簡易止水シート１０は、２枚のゴムシート１１ａ、１１ｂと、そのゴムシート１１ａとゴムシート１１ｂの間に挟み込まれて、縦方向及び横方向にそれぞれ複数個配置されたネオジウム磁石１２とで構成されている。   As shown in FIGS. 1 and 2, the simple water-stop sheet 10 used in this embodiment is sandwiched between two rubber sheets 11a and 11b and the rubber sheet 11a and the rubber sheet 11b. A plurality of neodymium magnets 12 are arranged in the lateral direction.

なお、図１では、下側のゴムシート１１ａのみを示し、上側のゴムシート１１ｂは省略している。   In FIG. 1, only the lower rubber sheet 11a is shown, and the upper rubber sheet 11b is omitted.

ここで、ゴムシート１１ａは、例えば、大きさＬ１×Ｌ２×ｔｓaが２００ｍｍ×２００ｍｍ×４ｍｍで、引き裂き強度が５ｋｇ／ｃｍ２以上である。また、ゴムシート１１ｂは、例えば、大きさＬ１×Ｌ２×ｔｓｂが２００ｍｍ×２００ｍｍ×４ｍｍで、引き裂き強度が５ｋｇ／ｃｍ２以上である。 Here, the rubber sheet 11a has, for example, a size L1 × L2 × tsa of 200 mm × 200 mm × 4 mm and a tear strength of 5 kg / cm 2 or more. The rubber sheet 11b has, for example, a size L1 × L2 × tsb of 200 mm × 200 mm × 4 mm and a tear strength of 5 kg / cm 2 or more.

また、ネオジウム磁石１２は、例えば、大きさＳ１×Ｓ２×ｔｍが５０ｍｍ×５０ｍｍ×１２．７ｍｍであり、縦方向に３個、横方向に３個の計９個が取り付けられている。   In addition, the neodymium magnet 12 has, for example, a size S1 × S2 × tm of 50 mm × 50 mm × 12.7 mm, and a total of nine pieces in the vertical direction and three in the horizontal direction are attached.

それと、ゴムシート１１ａ、１１ｂでネオジウム磁石１２を挟み込む際には、熱を加えて、ゴムシート１１ａとゴムシート１１ｂを融着させて貼り合わせる。   In addition, when the neodymium magnet 12 is sandwiched between the rubber sheets 11a and 11b, heat is applied so that the rubber sheet 11a and the rubber sheet 11b are fused and bonded together.

そして、図３に斜視図を示すように、配管１の破孔部２から漏水３が発生した場合には、その破孔部２に簡易止水シート１０を貼付するようにする。すなわち、破孔部２をゴムシート１１ａ、１１ｂで覆い、そのゴムシート１１をネオジウム磁石１２の磁力で配管１に密着固定する。   Then, as shown in a perspective view in FIG. 3, when water leakage 3 occurs from the broken hole portion 2 of the pipe 1, a simple water-stop sheet 10 is attached to the broken hole portion 2. That is, the hole 2 is covered with rubber sheets 11 a and 11 b, and the rubber sheet 11 is tightly fixed to the pipe 1 by the magnetic force of the neodymium magnet 12.

図４は、破孔部２に簡易止水シート１０を貼付した状態を示す斜視図であり、図５は、その断面図である。   FIG. 4 is a perspective view showing a state in which the simple water-stop sheet 10 is stuck to the broken hole portion 2, and FIG. 5 is a cross-sectional view thereof.

なお、図３、図４では、下側のゴムシート１１ａのみを示し、上側のゴムシート１１ｂは省略している。   3 and 4, only the lower rubber sheet 11a is shown, and the upper rubber sheet 11b is omitted.

このようにして、この実施形態においては、配管から漏水が発生した際に、迅速に応急的な止水を行うことができる。その結果、突発的な長時間の生産停止を回避することが可能となる。そして、恒久的な配管の復旧は後日計画的に実施することにより、生産活動に影響を及ぼさないようにすることができる。   In this way, in this embodiment, when water leaks from the pipe, it is possible to quickly and quickly stop the water. As a result, it is possible to avoid a sudden long-term production stop. Then, permanent pipe restoration can be carried out systematically at a later date so that production activities are not affected.

なお、この実施形態では、２枚のゴムシート１１ａ、１１ｂの間に複数のネオジウム磁石１２を挟み込んで製作した簡易止水シート１０を予め用意しておき、その簡易止水シート１０を破孔部２に密着固定するようにしているが、場合によっては、まず、破孔部２をゴムシート１１ａで覆い、その後に、ゴムシート１１ａの上から破孔部２の周囲に複数のネオジウム磁石１２を配置して、ゴムシート１１ａを破孔部２に密着固定するようにしてもよい。   In this embodiment, a simple water-stop sheet 10 produced by sandwiching a plurality of neodymium magnets 12 between two rubber sheets 11a and 11b is prepared in advance, and the simple water-stop sheet 10 is used as a hole portion. In some cases, the hole portion 2 is first covered with the rubber sheet 11a, and then a plurality of neodymium magnets 12 are placed around the hole portion 2 from above the rubber sheet 11a. The rubber sheet 11a may be disposed and fixed in close contact with the broken hole portion 2.

本発明の実施例として、上記の本発明の一実施形態を３００Ａ以上の工場用水送水配管に適用した。   As an example of the present invention, the above-described embodiment of the present invention was applied to a water supply pipe for factories of 300A or more.

その結果、上記の配管に漏水が発生した場合、従来は止水するまでに１０時間程度を要していたのに対して、３時間程度で止水をすることができた。   As a result, when water leakage occurred in the above-mentioned piping, it was possible to stop the water in about 3 hours, whereas conventionally it took about 10 hours to stop the water.

これによって、本発明の有効性が確認された。   This confirmed the effectiveness of the present invention.
