Problems solved by technology
[0003] However, in the prior art, when osmotic pressure loading is performed and CT continuous scanning is performed, it is found that the material of conventional pressurized osmotic equipment is usually composed of iron or steel materials, which cannot be well used by medical CT. The X-ray penetrates, and its structural design usually does not consider the influence of CT scanning, which makes the conventional pressurized infiltration device unable to meet the test conditions of CT scanning

The invention relates to a pressurized permeation device and a real-time scanning device matched with a medical CT, and belongs to the field of lossless detection of materials. The pressurized permeation device comprises a nitrogen gas cylinder, a gas-pressure meter, a reducing valve and a pressurized permeation device body. The pressurized permeation device body comprises a first pressing cover,a second pressing cover, a support pillar, a piston, a first transition joint and a second transition joint. The support pillar is of a stand column structure with a space cavity therein; one end of the support pillar is connected with the first pressing cover; the other end, far away from the first pressing cover, of the support pillar is connected with the second pressing cover; the piston is arranged in the space cavity and divides the space cavity into a first space cavity and a second space cavity; and the piston can move to any position of the space cavity. The pressurized permeation device body is made of aluminum. The pressurized permeation device is simple in structure, reasonable in design and strong in practicability. The aluminum is used as the material of the pressurized permeation device body, and thus the requirement of no generation of a relatively large influence during medical CT imaging can be met.
Description
technical field [0001] The invention relates to the field of non-destructive testing of materials, in particular to a pressurized penetration device and a real-time scanning device matched with medical CT. Background technique [0002] The seepage pressure will change the internal stress state of the rock and soil mass, and the change of the stress state will react on the rock and soil mass to cause the change of the permeability characteristics. In order to study the influence of permeable pressure on the internal structure of soil, many scholars use CT scanning technology to study the influence of osmotic pressure on the internal structure of soil, and try to study the expansion and closure of micro-cracks in rock and soil under the action of permeable pressure by means of observation. At the same time, it conducts systematic and in-depth research on the evolution law of permeability of rock and soil mass. [0003] However, in the prior art, when osmotic pressure loading ...
