Abstract:
(EN) The present invention relates to a 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 packer comprises: a cylindrical expansion member divided into multiple parts by means of a plurality of cut lines; an elastic member surrounding the expansion member, and preventing same from coming apart as the diameter of the elastic member is varied in accordance with whether the expansion member is expanded; a pressurizing member, provided inside the expansion member, for pushing the expansion member outward by means of hydraulic pressure; and a cylindrical support member provided inside the pressurizing member, and accommodating a water pipe through which water, supplied by a water supply member for supplying water, flows, and having a plurality of holes spaced a set distance apart in lengthwise and circumferential directions so that the water is sprayed in all directions.
(FR) La présente invention concerne une garniture d'étanchéité 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 comprend : un élément d'expansion cylindrique divisé en de multiples parties au moyen d'une pluralité de lignes de coupe ; un élément élastique entourant l'élément d'expansion, et empêchant celui-ci de s'écarter lorsque le diamètre de l'élément élastique varie en fonction de l'expansion de l'élément d'expansion ; un élément de mise sous pression, disposé à l'intérieur de l'élément d'expansion, pour pousser l'élément d'expansion vers l'extérieur par pression hydraulique ; et un élément de support cylindrique disposé à l'intérieur de l'élément de mise sous pression, et accueillant un tuyau d'eau à travers lequel s'écoule de l'eau fournie par un élément d'alimentation en eau, et ayant une pluralité de trous espacés d'une distance déterminée dans les directions longitudinale et circonférentielle de telle sorte que l'eau est projetée dans toutes les directions.
(KO) 본 발명은 수압을 이용하여 암반을 절개하도록 절개부위를 밀폐하여 밀폐공간으로 형성하도록 하는 수압을 이용한 암반절개를 위한 패커에 관한 것으로, 복수의 절개선을 통해 복수개로 분할되는 원통형의 확장부재, 상기 확장부재를 감싸고, 상기 확장부재의 확장여부에 따라 지름이 가변되면서, 상기 확장부재의 이탈을 방지하는 탄성부재, 상기 확장부재의 내부에 구비되어 수압을 통해 상기 확장부재를 외측방향으로 밀어주는 가압부재, 및 상기 가압부재의 내부에 구비되어, 물을 공급하는 물공급부재에 의해 공급되는 물이 지나는 수관을 수용하고, 사방으로 분사되도록 복수개의 분기홀을 둘레 및 길이방향으로 일정간격 이격하여 형성한 원통형상의 지지부재;를 포함한다.
