Description
Technical field
A kind of concrete permeability experimental rig of the utility model, belongs to concrete test detection field.
Background technology
The permeability of concrete is generally described using seepage-resistant grade and permeated height at present.Seepage-resistant grade refers to according to mixed
Concrete is divided into P4, P6, P8, P10, P12, is more than P12 by the maximum water pressure that solidifying soil test specimen can bear in impermeability test
Deng six grades, the corresponding hydrostatic pressure for indicating that 0.4,0.6,0.8,1.0 and 1.2MPa can be resisted and it is impermeable, in other words
One group 6 conical test specimens when being concrete impermeability test（Upper diameter 175mm, lower diameter 185mm, high 150mm）In 4
Different maximum water pressure when test specimen does not seep water.Its test result is qualitative description, cannot use infiltration coefficient quantitative description.
Permeated height be exactly under certain hydraulic pressure it is constant for 24 hours after, by conical test specimen（Ibid）It vertically rives at the diameter of face, with 10
Measuring point seeps water infiltration height of the average value as the test specimen of height, then using the average value of 6 test specimen deep water height as changing
The permeated height of group test specimen, the relatively density of concrete.The above test result is that cannot use infiltration for qualitative description
Quantifies describe the permeability of concrete.

Steel brush feather plucking is used below, is then fixed concrete sample 9 and the pressing plate of above and below 12 by fastening bolt 13, and in coagulation
Rubber washer 11 is placed between native test specimen 9 and pressing plate 12.The cavity that 7 pipeline of drainpipe is passed through into pressing plate 12 and concrete sample 9
It connects, opens the water filling into the cavity of concrete sample 9 of water injection pipe 5, until drainpipe 7 is discharged, by water injection pipe 5 and drainpipe 7
Valve close.
Concrete sample 9 is placed in pressurized tank 10, cover board 8 is fixed on pressurized tank 10 by fastener 3, in institute
State placement seal ring 4 between cover board 8 and pressurized tank 10.The valve of 1 position of opening water inlet, the water filling into pressurized tank 10, until
Exhaust pipe 6 is discharged, and closes the valve of exhaust pipe 6.7 valve of drainpipe is opened, water inlet 1 is connected into pressue device, is pressurized to
0.5MPa measures the water percolating capacity of concrete sample 9 by drainpipe 7.After water percolating capacity is stablized in certain time, start to read, so
Afterwards according to Darcy's law, the infiltration coefficient of concrete sample 9 is calculated.
