Abstract

In contrast to the mechanical stirring method in which the ground soil and the modifying
material are mixed and stirred by stirring blades and the improved body is formed in the ground, the high
pressure injection stirring method is a method in which the improved diameter is changed due to soil
condition and so on. There is a possibility that it can be changed with, and a method for easily confirming the
shape, particularly the improved diameter, is highly desired. In this research, the authors propose and propose
a method that can make "visualization" of this improvement situation and confirm the improved diameter in
real time. Confirmation was made by measuring water quality in multiple items. From the results, it was
confirmed that pH and the values of the other 5 items changed at the same time. And the change was due to
the arrival of the cement slurry. Therefore, it can be said that real-time measurement is possible by
visualization of improved diameter by water quality measurement conducted this time.
