Abstract:
1. A method for constructing a chemically-inflatable bag for use as an obstruction in a formed cavity, the method comprising: providing an elongated sleeve that includes one or more longitudinal seams that substantially traverse a length of the elongated sleeve, wherein the elongated sleeve having an accessible interior; folding the elongated sleeve along an axis that is substantially perpendicular to the one or more longitudinal seams to form a crease, wherein the crease creates a watertight, releasable seal that divides the interior of the elongated sleeve into a first section and a second section; inserting a first reactant into the first section via a first opened end of the elongated sleeve; forming a first chamber to enclose the first reactant by fixedly sealing the first opened end; inserting a second reactant in the second section via a second opened end of the elongated sleeve that is arranged in opposed relation to the first opened end; forming a second chamber to enclose the second reactant by fixedly sealing the second opened end; and rolling together a portion of the first chamber and a portion of the second chamber to produce a cylindrical coil, wherein the process of rolling reduces a realized volume of the first chamber and the second chamber, wherein the cylindrical coil is selectively unwound upon applying an unfurling action to the chemically-inflatable bag, and wherein the unfurling action comprises:
