[0031] Working principle: when the whole device is moved to the position to be measured for measurement operation, first, place the installation box 100 at the initial point of measurement, rotate the two T-shaped anchor rods 5 into the soil in reverse, and use the engagement force between the T-shaped anchor rod 5 and the soil to fix the installation box 100.
