The bayonet unit of snapping, described to divide tubular body with interlayer, interlayer is connect by pipe fitting with cooling device.
1. the present invention also provides carry out one-dimensional consolidation model analysis test using above-mentioned soil body one-dimensional consolidation experimental rig
Method, comprising the following steps:
1) selection needs to do the soil body analyzed, snapping is complete and extract the soil body one-dimensional consolidation of air hole blocking and test dress
It sets in the insertion soil body；
2) air hole is closed using blocking, opens cooling device and inject coolant liquid into interlayer, makes the soil body in tube body
Cooling consolidation；
3) soil body one-dimensional consolidation experimental rig is entirely extracted again, opens bayonet unit and is separately in charge of body for freezing consolidation
The soil body takes out, then carries out dissection by the different of depth；
4) mechanical test analysis is carried out to each section of soil body.
The soil body that above-mentioned soil body one-dimensional consolidation experimental rig can obtain sampling during sampling carries out cooling solid
Knot processing, is easily deformed fragility after avoiding the sampling of the soil body, is unlikely to deform after the soil solidifying sampled, can be more true
The state for accurately reacting the soil body, is conducive to establish analysis model.
