Saturating of capillary is although easy to use, but saturation time is long, and higher requirement is not achieved in saturation degree；Carbon dioxide is saturated soil sample
Method needs to prepare the carbon dioxide of suitable concentration in advance, and time is long, is unfavorable for the convenience used；Back pressure saturation method due to
The limitation of equipment, it is affected more complicated, but have the advantages that saturated velocity is fast, saturation degree is high.
Currently, laboratory test saturation soil sample is to carry out at normal temperatures and pressures, and disposably put the water needed for soil sample and pour
Saturation immersion is carried out in soil sample, causes soil sample saturation to be not thorough so that the physical mechanics test result of soil sample is practical with engineering
Result difference farther out.
Invention content
The technical problem to be solved by the utility model is to provide a kind of experimental rigs of saturation soil sample, in suitably pressurization shape
