Description
【発明の詳細な説明】 本発明は配管の漏洩防止方法に関する。[Detailed description of the invention] The present invention relates to a method for preventing piping from leaking.
従来、土中、コンクリート等の中に埋設された配管から
、流通流体の漏洩が発生した場合には管内部に薬液を注
入固化して漏洩を防止するグラウト法が一般に用いられ
ている。しかし。BACKGROUND ART Conventionally, when a leak of circulating fluid occurs from a pipe buried in soil, concrete, etc., a grouting method is generally used in which a chemical solution is injected into the pipe and solidified to prevent the leakage. but.
グラウト法に用いられる薬液は無機系、有機系を問わず
９本質的に配管材料に比べ物性が劣り。The chemical solutions used in the grouting method, regardless of whether they are inorganic or organic9, have essentially inferior physical properties compared to piping materials.
強度、／−ル性、耐久性の面で抜本的対策とはなり得な
いという不具合があった。There was a problem in that it could not be a drastic countermeasure in terms of strength, rigidity, and durability.
本発明は上記不具合を解消するために提案されたもので
、以下１本発明を図に基づき説明する。The present invention was proposed to solve the above problems, and one of the present inventions will be explained below with reference to the drawings.

よって発生する圧力波を示す。In the figure, 2 is a pipe buried in soil or concrete, etc., 3 is a flange joint, 4 is a backing material, 5 is a highly ductile metal sleeve, 6 is gunpowder, and 7 is a pressure wave generated by the ignition of gunpowder 6. show.
しかして、埋設配管２の漏洩を防止するには。Therefore, to prevent leakage of the buried pipe 2.

止する。A metal sleeve 5 is installed at the leakage point, for example, on the inner surface of the joint 8 of the pipe 2.Next, an appropriate amount of gunpowder 6 set inside the sleeve 5 is ignited, and the generated pressure wave 7 causes the metal sleeve 5 to Leakage is prevented by expanding and deforming the pipe 2 and crimping the outer periphery of the metal sleeve 5 to the inner periphery of the joint portion 8 of the pipe 2.

とが出来るとともにその耐用年数が大巾に延長する。Therefore, in the conventional grouting method, the sealing property is obtained by solidifying the liquid substance, so the pressure resistance is at most 5 kg/cnl.
-gt, but since the method of the present invention uses a metal sleeve, the pressure resistance can be increased to 10 kg/(7 d-g or more, or several tens of kg/cal-g or more in some cases). The service life is greatly extended.

Claims (1)
、該金属性スリーブの内部で火薬を爆発させ、その圧力
波により配管の内周に金属スリーブの外周を圧着させる
ことを特徴とする配管の漏洩防止方法。The method is characterized in that a metal sleeve is installed on the inner surface of the leakage point of the pipe, and then gunpowder is exploded inside the metal sleeve, and the resulting pressure wave causes the outer periphery of the metal sleeve to be crimped to the inner periphery of the pipe. How to prevent piping from leaking.
