Make, move down screw rod 211, downward pressure is applied to top cover 316 by ring 4 of measuring one's own ability, so Control Assay do not occur it is swollen
It is swollen, it is not produced vertical deformation, the reading of offset table 310 is returned to initial reading, until the stable reading of measurement table 410
When, now screw rod 211 is the water swelling power of soil body sample this moment to pressure caused by sample by measuring one's own ability ring 4, measurement table
The data gathered on 410 are the expansion force value of soil body sample.
When the present apparatus measures, dial gauge control changes in 0.01kpa in 0.01m amplitudes of variation, loads change, then corresponded to swollen
Expansive force volume deformation and the loads change of consolidation compression are substantially constant, and regulating time short time effect can be ignored, symbol
Close centrifugal modeling code requirement.
In summary, the measurement table 410 and the number of offset table 310 that the utility model embodiment is received by intelligent terminal 5
According to automatically adjusting servomotor 210, and then drive screw 211 moves down and sample is further applied load, and monitors the lotus of sample in real time
Change and deformation quantity are carried, the complex steps that load is adjusted by adjusting the quantity of loading counterweight is avoided, ensure that sample perseverance body
Expansive force measurement under cumuliformis state, improves the accuracy that compression performance and expansive force measurement are consolidated to soil body sample.
