| description | The utility model discloses a double-end water plugging device for observing a working face overlying strata water flowing fractured zone. A first avoiding assembly is matched with a second avoiding assembly to support a main body assembly, so that a first plugging capsule and a second plugging capsule avoid the hole wall of a drill hole in the process of extending into the drill hole; the double-end water plugging device can prevent the first plugging capsule, the second plugging capsule and the hole wall of the drill hole from being damaged due to friction. The device is characterized by comprising a main body assembly, first avoiding assemblies and second avoiding assemblies, the two first avoiding assemblies are symmetrically arranged on the main body assembly, the two second avoiding assemblies are symmetrically arranged on the main body assembly, and the center lines of the first avoiding assemblies are perpendicular to the center lines of the second avoiding assemblies; the main body assembly is compos |
