Test device 100 can also cooperate with existing other modes to realize that concrete permeability detects, and the present embodiment is simultaneously not construed as limiting.
The concrete operations process of concrete permeability testing device 100 described in the present embodiment is as follows: controlling two gas first
The synchronous elongation of cylinder, gland 15 are then moved upwards with far from test barrel 12, the first inner ring 131 and the first outer ring 141 respectively including bullet
It is moved upwards under the action of spring 135 and outer spring 145, and scalable inner corrugated pipe 136 and scalable outward corrugated tube 146 are
Stretched upwards under the drive of one inner ring 131 and the first outer ring 141, when the first inner ring 131 and the first outer ring 141 move to setting away from
From when, then in limit rope 137 and outer limit rope 147 be straightened, when specific setting, when outer limit rope 147 is straightened, the work of cylinder
Stopper rod stretches out about 1/5th length upwards, and when interior limit rope 137 is straightened, then the first inner ring 131 just moves to second
Outside cavity, i.e., the first inner ring 131 just protrudes from inner cylinder 121, at this point, 141 upper surface of the first outer ring and 152 lower end of mounting ring
Spacing is formed between face and is greater than 200 height of concrete sample, specially between the first exterior seal ring 143 and inlet seal circle 153
Spacing be greater than the height of concrete sample 200, the be put into order to operator's concrete sample 200 in first inner ring 131
Guarantee that concrete sample 200 and the first inner ring 131 are coaxial as far as possible on one inner seal ring 133, when placement；Then two cylinders are driven
Synchronous, gland 15 then move downward, and after moving a fixed spacing, the inlet seal circle 153 in mounting ring 152 is connected to mixed
Solidifying 200 upper surface of soil sample simultaneously drives concrete sample 200 to move downward, and the lower surface of lid 151 is then connected to outside first
Sealing ring 143, under the active force of gland 15, inner spring 135 and outer spring 145 are all compressed, so that sealing in first
133 sealing of circle is pushed against in 200 lower end surface of concrete sample, and the sealing of the second inner seal ring 134 is pushed against in the second cavity bottom, and first
The sealing of exterior seal ring 143 is pushed against in 151 lower surface of lid, and the second exterior seal ring 144 is sealed against in the first cavity bottom, and into
Airtight seal 153 is then pushed against in 200 upper surface of concrete sample, may make scalable inner corrugated pipe 136 and concrete sample
The first annular seal space that formation one is connected to venthole 11a between 200 lower end surfaces, and lid 151 and 200 upper end of concrete sample
Second seal chamber being connected to air inlet 151a, 200 outer wall of concrete sample and scalable outward corrugated tube 146 are formed between face
Between form third seal chamber, one side is avoided after the gas that is passed through by air inlet 151a passes through concrete sample 200 and is let out
Leak, be conducive to guarantee air pressure stability, on the other hand ensure that along concrete sample 200 axially across gas can
It is discharged by gas outlet, in order to subsequent detection；Then by intake interface in the way of existing mode or above-mentioned patent disclosure
It is passed through the high pressure gas of setting air pressure, high pressure gas penetrates into first annular seal space by the second sealing ring, and passes through outlet interface
Detection is permeated and flow, the flow velocity of gas out, then the calculation permeability coefficient in the way of existing way or above-mentioned patent disclosure
?；After the completion of test, driving cylinder elongation can drive concrete sample 200 to it under the action of inner spring 135
Upper end protrudes from test barrel 12 and the first outer ring 141, and the first outer ring 141 can't limit under the action of outer limit rope 147
Concrete sample 200 processed takes out, and manually or by clamping machine by concrete sample 200 takes out, aforesaid way operation letter
It is single, convenient, be conducive to improve integrated testability efficiency.
Moreover, air pressure is higher in the second seal chamber of the present embodiment, therefore it directly passes through mounting ring 152 and cooperates inlet seal circle
153, can adapt to high pressure conditions, and first annular seal space and third seal chamber can then accommodate the gas after infiltration, in gas
It presses relatively small, therefore biggish pressure can't be generated to scalable inner corrugated pipe 136 and scalable outward corrugated tube 146；Meanwhile
The interior sealing telescopic component 13 and external seal telescopic component 14 of the present embodiment connect with inner cylinder 121 and the sliding of outer barrel 122 respectively
It connects, therefore interior sealing telescopic component 13 and external seal telescopic component 14 can be by taking out, in order to its component hair in 12 body of test barrel
Life is replaced in time with bad when.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model.
Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical
Outside novel scope of protection of the claims.
