Abstract: front page image
(EN)The present invention relates to a cylindrical packer for splitting a rock by means of hydraulic pressure, the packer sealing the area around a cut, forming a sealed space, to split a rock by means of hydraulic pressure. The cylindrical packer comprises: a cylindrical pressurizing member divided into multiple parts by means of a plurality of cut lines; a cylindrical push member, provided inside the pressurizing member, for pushing the pressurizing member outward by means of hydraulic pressure; a water supply member for supplying water to the push member; and an elastic member which surrounds the pressurizing member, and the diameter of which varies in accordance with whether pressure is applied by the pressurizing member, wherein the cut lines are zig-zag shaped, and the pressurizing member and push member are made of metallic material.
(FR)La présente invention concerne une garniture d'étanchéité cylindrique pour faire éclater une roche par pression hydraulique, la garniture d'étanchéité scellant la zone autour d'une découpe, de sorte à former un espace étanche, pour faire éclater une roche par pression hydraulique. La garniture d'étanchéité cylindrique comprend : un élément cylindrique de mise sous pression divisé en de multiples parties au moyen d'une pluralité de lignes de coupe ; un élément de poussée cylindrique, disposé à l'intérieur de l'élément de mise sous pression, pour pousser l'élément de mise sous pression vers l'extérieur par pression hydraulique ; un élément d'alimentation en eau pour fournir de l'eau à l'élément de poussée ; et un élément élastique qui entoure l'élément de mise sous pression, et dont le diamètre varie selon qu'une pression est appliquée ou non par l'élément de mise sous pression, les lignes de coupe étant en forme de zigzag, et l'élément de mise sous pression et l'élément de poussée étant faits d'un matériau métallique.
(KO)본 발명은 수압을 이용하여 암반을 절개하도록 절개부위를 밀폐하여 밀폐공간으로 형성하도록 하는 수압을 이용하여 암반절개를 위한 실린더형 패커에 관한 것으로, 복수의 절개선을 통해 복수개로 분할되는 원통형의 가압부재, 상기 가압부재의 내부에 구비되어 수압을 통해 상기 가압부재를 외측방향으로 밀어주는 실린더 형태의 푸쉬부재, 상기 푸시부재에 물을 공급하는 물공급부재, 및 상기 가압부재를 감싸고, 가압부재의 가압 여부에 따라 지름이 가변되는 탄성부재를 포함하되, 상기 절개선은 지그재그로 형성하고, 상기 가압부재 및 푸쉬부재는 금속재질로 형성한다.
