Water pump (6) into the Organic glass column (3) equipped with the original state soil body confession/draw water so that in Organic glass column (3) in the original state soil body
Water level reaches initial underground water buried depth；Then soil sample depth, underground water buried depth are inputted in control software, monitor duration, is initial
Upper pressure clicks start button, and the dual-purpose water pump of supercharging/negative pressure (6) with wireless receiving/transmitting device is to equipped with the original state soil body
Confession in Organic glass column (3)/draw water, the electric controlling stepless variable speed motor (11) with wireless receiving/transmitting device drive screw rod (9) and apply
The original state soil body of the flattening bench (10) into Organic glass column (3) applies pressure, while wireless receiving and dispatching hydraulic pressure sensor (12) monitors
The variation in water pressure of original state soil body different location in Organic glass column (3), fibre optical sensor (13) monitor Organic glass column (3) Central Plains
The sedimentation of shape soil body different location changes；
Step 5, test data is obtained：After the completion of test, the processing module on computer (14) in control software utilizes storage
Test data provides the image of the sedimentation value variation of different soil during variation in water pressure and final sedimentation value, or/and provides
The image and final sedimentation value of the sedimentation value variation of different soil during the pressure that hydraulic pressure and top apply changes simultaneously.
