Description
Technical field
The utility model relates to concrete NDT technical fields, and in particular to a kind of concrete impervious instrument.
Background technique
The anti-permeability performance of concrete is the important indicator and each engineering quality supervision for evaluating concrete quality quality and durability
The required Inspection Index for stringent concrete Quality Control of standing.Concrete have seepage resistance demand engineering: as water conservancy project, harbor work, road and bridge engineering,
Construction of underground structure etc..So-called anti-permeability performance refers to that material used in structures can resist water or other liquid (light oil, again
Oil) performance permeated under pressure of medium.
Tested in the prior art using impermeability of the concrete impervious instrument to concrete: testing crew is needed to one group 6
Sealing material is smeared in sample outer surface respectively, then each sample is respectively pressed into die sleeve with pressure testing machine, then will be pressed into
The die sleeve of test specimen is moved on testing stand respectively and is fixed with 6 bolts, to improve the leakproofness of die sleeve and testing stand, reduces experiment
In the process, the probability for thering is water to ooze out from the junction of die sleeve and testing stand.
Since the comparison that 6 die sleeves lean on the testboard of concrete impervious tester is close, when screwing or dismantling,
The space of used tool is very limited, causes installation, disassembly inconvenient；And each die sleeve require by 6 bolts into
Row is fixed, and 6 die sleeves just need to screw or unclamp 36 bolts, relatively time-consuming, keep testing efficiency low.
