Existing automatic measurement infiltration coefficient simultaneously greatly shortens the test period.And during gas permeability measurement, on the outside of sample with
Seepage channel strong influence between the test cylinder accuracy of result, the patent take vaseline to seal this channel, seal
Effect shortcoming.
105866337 A of Chinese patent application CN discloses slurry shield excavation face mud film forming and mud under a kind of high pressure
Film test device for air tightness and method, device include pneumatic supply, the slurry penetration room, backpressure device and the collection that are placed in insulating box
Water installations；Slurry penetration room is steel die type tube structure.The main purpose of this patent is to develop a kind of grouting test device, simulation
Diffusion forms mud membrane process to mud in the earth formation, then passes through the airtightness and resistance to pressure energy of charged pressure gas detection mud film
Power cannot carry out testing permeability to the conventional reinforcing body sample that grouting test obtains, evaluate grouting consolidation effect.
101893617 B of Chinese patent CN discloses a kind of test limit row tunnel grouting circle hydraulic pressure reduction rule resistant to pressure
Experimental rig, including pressure chamber, simulation tunnel, pressurized equipment and measurement equipment are mainly used for Grouting Circle hydraulic pressure reduction rule
Test, wherein Grouting Circle is substituted using the uniform analog material of human configuration, it is difficult to be reflected under the conditions of true slip casting and be reinforced
Body state is only capable of block-water performance variation caused by reflection Grouting Circle thickness changes.
