Abstract

PURPOSE: To reduce cost, and enhance workability by sealing a drug or the like expandable through reaction in a freely expandable bag body, and allowing the bag to be lowered at a predetermined depth, and thereafter forming a plug through reaction. CONSTITUTION: A bag body 50 being made up of elastic rubber or synthetic material or the like consisting of elastic rubber and leather and expandable through inner pressure is sealed therein with a drug 51 such as, e.g. carbon dioxide or synthetic resin that creates reaction with heat, an application of water, or a lapse of time and expands or generates gases per se in a manner blending cement, sand, fiber material 52 for gravity control and reinforcement. The bag body 50 is descended at a predetermined depth via wire 53, as a result, a plug is formed through a reaction of the drug 51 and its expansion.
