Abstract

PURPOSE: To prevent the flying-high of slime in case of the casting of the concrete by installing a bag body into an excavated pit while strengthening the supporting force of a nose as well as preventing the sinking of a structure by expanding and solidifying the bag body.
CONSTITUTION: A bag body 2, etc. are installed at the bottom of an excavated pit 1 excavated to the ground by fixed depth, and concretes 6 are placed. After concrete is hardened, a fluid 7 is fed into the bag body 2, and soil, which is scattered when excavation, slime, etc. are pressed together. An expanding coagulant 8 is charged into while extracting the fluid 7, and then the expanding coagulant 8 is expanded.
