Resistivity detection device using ground improvement wing

摘要

The specific resistance detection device using the ground improvement wing of the present invention is a ground improvement device having a common rotation prevention wing and a stirring wing, and using a specific resistance detection electrode installed on the common rotation prevention wing, Detect and monitor the condition of the ground. The ground change monitoring device 20 outputs the measurement signal by measuring the specific resistance when the excavated soil and the excavated soil and the ground improvement material are mixed using the electrode 9 installed on the anti-rotation blade 4 of the ground improvement device Do. The measurement signal is transmitted from the receiving unit 21 connected to the electrode 9 and transmitted to the computer 24 through the wireless transmitter 22 installed in the water swivel 10. The computer 24 receives the measurement signal, determines ground change and the like from the rate of change in resistivity, and displays a determination result signal on a display. The electrode 9 is installed at the outer peripheral end 4 d or the central portion of the blade 4 a of the anti-rotation wing 4.
