Abstract
The present invention is directed towards an apparatus for providing a nonlabor-intensive process for sealing an opening formed in the ground with a chemically-inflatable bag. The chemically-inflatable bag contains two or more chemical reactants, one of which is a liquid reactant that is initially stored in a liquid-containing device. The liquid-containing device has a removable cap, which upon removal or breakage of the cap permits the liquid reacting agent to contact and react with another reacting agent. The chemical reaction produces carbon dioxide, which expands the chemically-inflatable bag from a collapsed condition to an inflated condition. In the inflated condition, the chemically-inflatable bag fills and protects the integrity of the formed cavity.
