摘要： A method of destroying a brittle body by molding around an elastic tube or an elastic tube in which is inserted a plastic wire or a heat-fusible member for defining a charging hole where the member or tube is partly exposed at the surface of the brittle body, and, after pulling out the elastic tube or fusing the heat-fusible member, an expandable splitting agent capable of expanding by hydration is charged into the charging hole and subjected to hydration-expansion to destroy the brittle body. In another form, a water-impermeable film enclosing an expandable splitting agent capable of expanding by hydration therein is previously buried in a brittle body in a relation partly exposed at the surface of the brittle body, and, after aperturing the exposed end of the water-impermeable film, the expandable splitting agent is subjected to hydration-expansion to destroy the brittle body.
摘要翻译：通过在弹性管或弹性管周围模制脆性体的方法，该弹性管或弹性管插入塑料线或热熔部件，用于限定构件或管部分在脆性体的表面露出的充电孔并且在拉出弹性管或熔化热熔部件之后，将能够通过水合膨胀的可膨胀分解剂装入充填孔中并进行水合膨胀以破坏脆性体。在另一种形式中，包含能够通过其中水合膨胀的可膨胀裂解剂的不透水薄膜预先以部分暴露在脆性体表面的关系中并且在打开水的暴露端之后埋入脆性体中可膨胀裂解剂进行水合膨胀以破坏脆性体。
