ABSTRACT:
A plug for a passage such as a shot hole in the ground, a pipe or a tube includes an inflatable flexible sleeve closed at each end by a rigid plug, the plugs being interconnected by a metal pipe, with a compressed air cylinder in the pipe closed by an electrical valve which can be opened by a battery power pack separate from the plug to permit air under pressure to escape into the pipe and through apertures therein into the sleeve, inflating the latter to seal the passage.
