Description
Technical field
The utility model relates to concrete durability experiment field in civil engineering work, particularly a kind of wetting-drying circular tester.
Background technology
In some extra large work engineerings of China, Tidal zone concrete is in the time that the marine denudation suffering destroys, threaten the most serious problem of concrete works permanance to be: the villaumite in seawater is under the effect of this drying and watering cycle, can accelerate the transmission process in concrete, and the erosion of villaumite causes the removing blunt of reinforcing steel bar in concrete, thereby it is swollen to make reinforcing bar produce rust, and then accelerate the performance degradation of reinforced concrete structure.In concrete durability experiment, conventionally adopt testing laboratory's drying and watering cycle method to carry out marine environment that is virtually reality like reality, also accelerate the corrosion process of reinforcing bar simultaneously, to shorten the test period.
At present a large amount of scholars are based on this background, the corresponding research also launching, but there are a lot of problems in this test:
1, the artificial timing of general using move test block, and general concrete test is heavier.
2, also differ larger for the means of drying and watering cycle, can not well simulate the marine environment of Tidal zone.
3, finally cause that Efficiency is low, data accuracy is inadequate.
Therefore be necessary to study a kind of wetting-drying circular tester, to instruct and specification experimental study, improve test figure accuracy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of wetting-drying circular tester, can simulate the state of the chloride erosion xoncrete structure in the seawater of Tidal zone, can control different drying and watering cycle parameters, improves efficiency and the test accuracy of test.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of wetting-drying circular tester, comprise casing, in casing, be provided with test-piece stand, the top of test-piece stand is provided with shower nozzle, in casing, be provided with the space for holding test(ing) medium, this space is connected with shower nozzle by pump, and cycle timer is electrically connected with pump;
On casing, be also provided with at least one air-dry electric fan facing to test-piece stand.
Described test-piece stand has certain altitude, the space that in the casing of test-piece stand below, sky is configured for holding test(ing) medium, and the bottom of casing is communicated with pump.
Top at casing is provided with case lid, is provided with the automatic curtain for blocking air-dry electric fan in the position that air-dry electric fan is installed.
Described air-dry electric fan is multiple, and air-dry electric fan is positioned at the both sides of casing.
Described bottom half is also provided with freeing port.
Shower nozzle is by spraying bracket supports above test-piece stand.
A kind of wetting-drying circular tester that the utility model provides, by the shower nozzle of employing and the mode of pump ejection test medium, realize the endurancing of concrete sample drying and watering cycle, the cycle timer of setting can be realized automatic drying and watering cycle, to reach the requirement of test.The air-dry electric fan arranging can be simulated sea wind, also can accelerate the dry of concrete sample, improves test efficiency.The utility model device can wetting-drying test object, have simple and practical, flexible to operationly, work efficiency is high, the advantage of test findings stability.
