Title:
FINISH SHAPE MANAGEMENT METHOD AND DEVICE OF CHEMICAL INJECTION
Document Type and Number:
Japanese Patent JP2023173989
Kind Code:
A
Abstract:
To monitor change in a ground of a chemical penetration range before the chemical is solidified in real time immediately after injection, at the time of chemical injection in ground improvement.SOLUTION: At the time of chemical injection in ground improvement, chemical containing microbubbles and nanobubbles is injected to a ground 8, and change in amplitude of elastic waves (for example, sound waves) propagating through the ground 8 including a chemical injection part is measured immediate after the chemical injection, for example, using acoustic tomography using an oscillator 22 and a receiver 32 inserted into holes (20, 30, 31 and 16) provided in the ground 8, and a chemical penetration range (improvement body A) is monitored in real time before the chemical is solidified.SELECTED DRAWING: Figure 6
