Abstract
PURPOSE: To save breaking work for concrete by a method in which a protective bag is attached to a thin steel plate attached to an iron bar cage, which is closely contacted with the underground wall, the protective bag is expanded, concrete is placed and hardened, and then the protective bag is removed.
CONSTITUTION: A protective bag 2 is fixed to a thin steel plate 3 attached to the shear connector-fitting place of an iron bar cage 1. The iron bar cage 1 is erected in a pit 4 excavated underground, water, etc., is injected into the protective bag 2 by a pump 9 to expand it in such a way as to closely contact the bag 2 with the underground wall 5 and the thin steel plate 3, and then concrete is placed. A joint iron bar 6 is surrounded by the protective bag 2 and serves to prevent the creeping of placed concrete 7. After the placed concrete 7 has set, excavation is made, liquid inside the protective bag exposed is removed, the protective bag 2 is removed, and the joint iron bar 6 is exposed and joined.
