Description
Technical field
This utility model relates to a kind of concrete permeability resistance test sealing device, belongs to concrete NDT device technique neck
Territory.
Background technology
Concrete permeability resistance is one of important indicator of concrete durability, and impermeability directly affects the anti-erosion of concrete
Performance, a large amount of ocean engineering construction, can propose higher requirement to anti-erosion of concrete especially at present.Therefore, concrete
Impermeability more should be paid attention to.And the most important link of concrete permeability resistance test is exactly the encapsulation process of test specimen, seal
The bad anti-permeability performance that just cannot accurately test concrete of effect, also cannot provide concrete mix number accurately for engineering
According to, lose directive significance.
Sealing means of the prior art is more, and such as Publication No. CN204177655U, entitled " one is for concrete
The sealing device of Standard Test Method for Permeation Resistance " utility model patent, this patent uses the mode of latex tubing knotting, by die sleeve and test specimen it
Between the most fixing, thus realize preventing the purpose that surrounding leaks, its sealing is the best, still has one between test specimen side and die sleeve
Fixed gap, result of the test is not accurate enough.
And for example, Publication No. CN105181548A, entitled " a kind of for concrete impermeability test encapsulant and examination thereof
Proved recipe method " patent of invention, this patent uses butter to add the mode of cement and seals test specimen, though the method that butter adds cement
So cheap, but inconvenient operation, inefficient, and result of the test can affect greatly by the uniformity coefficient smeared.
Utility model content
This utility model aims to solve the problem that result of the test in prior art is inaccurate and the inefficient problem of detection, carries
Go out a kind of new concrete permeability resistance test sealing device, by being sleeved on test specimen by elastic seal cartridge, it is achieved seal effect
The best, that detection efficiency is high purpose.
In order to realize foregoing invention purpose, the technical solution of the utility model is as follows:
A kind of concrete permeability resistance test sealing device, it is characterised in that: include die sleeve and for being sleeved on test specimen
Elastic seal cartridge, described elastic packing is sheathed on inside described die sleeve.
Further, described elastic seal cartridge is the one in rubber finger sleeve, silicone rubber sleeve, has good springiness, low cost
Advantage.
Described die sleeve, elastic seal cartridge be shaped as adaptive with test specimen round table-like, suitability is good, and sealing is more preferably.
The upper bottom surface a diameter of 125～155mm of described elastic seal cartridge, bottom surface a diameter of 135～165mm, height is
145～155 mm, thickness is 1.5～3.0mm.
Described die sleeve is steel die sleeve, and intensity is more preferable, it is ensured that under a certain pressure, being smoothed out of test；It addition, die sleeve
Height more than test specimen, convenient test specimen is implemented pressure, detects.
The beneficial effects of the utility model:
(1) this utility model is by arranging elastic seal cartridge between test specimen and die sleeve, is sleeved on test specimen during detection
On, it is achieved test specimen surrounding is sealed, prevents water from oozing out from surrounding, affect the purpose of accuracy, and need not test specimen outer surface
Smearing, directly the mode of suit, has simple in construction, the higher advantage of detection efficiency.
(2) a diameter of 175mm of upper bottom surface, a diameter of 185mm of bottom surface of the test specimen made by GB, height is 150mm,
The upper bottom surface a diameter of 125～155mm of elastic seal cartridge of the present utility model, bottom surface a diameter of 135～165mm, height is
145～155, thickness is 1.5～3.0mm, elastic seal cartridge be dimensioned slightly smaller than test specimen, the elastic packing in this size range
Set both can guarantee that elastic seal cartridge can be sleeved on test specimen smoothly, can guarantee that again certain consolidation degree, and laminating degree is good, it is achieved
Good anti-seepage effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-die sleeve, 2-elastic seal cartridge, 3-test specimen.
