Abstract
PURPOSE: To increase the bearing force of the tip portion of concrete structure by a method in which concrete is placed on a flexible bag with a soft and expandible inside partition and set, a fluid is charged into one compartment of the bag to solidify the ground, and while drawing out the fluid, a grout is injected.
CONSTITUTION: A flexible bag 4 of rubber, etc., having a partition with through- pipes 2 and 3, is placed at the bottom of an excavated pit 1, an iron bar 5 is placed, and then concrete 7 is placed on the upper part of the bag 4 through a trimie tube. After the concrete 7 has set, a low-viscous fluid is charged through the through pipe 2 into one compartment 9 of the bag 4 to expand it in such a way that excavated residual soil and slime 12 are solidified by pressing. Then, while drawing out the fluid 8 through the through-pipe 2, a solidifiable fluid 11 is injected through the through-pipe 3 to expand the compartment 10 of the bag 4 in such a way as to embed a space formed by the pushing pressure of the compartment 9 of the bag 4 and to solidify it.
