Technical field
The utility model belongs to road and bridge detection field, in particular to a kind of concrete structure surface layer hollow imperfection detection dress
It sets.
Background technique
In field of civil engineering, it is often necessary to pour a large amount of concrete structure.And due to construction quality, concrete mixes and stirs
The factors such as quality influence, and concrete structure easily has dense surface but proximal from internal hollowing phenomenon.Hollowing will lead to concrete and pour
Quality decline is built, i.e. structural strength, elasticity modulus is insufficient, and then causes the qualitative problems of construction such as Lack of support, serious meeting
Jeopardize normal use safety and the people life property safety of structure, so the pouring quality detection of concrete structure seems especially
It is important.
There are mainly two types of methods for currently used concrete structure surface layer pouring quality detection method.One is indirect method,
Such as the rebound strength on concrete structure surface layer is surveyed using reisilometer, determine that surface strength is enough according to rebound value, and then push away
Export surface layer pouring quality.Pouring quality is detected using the concrete NDT instrument based on sonic detection.These methods cannot obtain
The data such as accurate surface layer hollowing location and range, and there are the disadvantages of at high cost, not easy to operate.Another kind is direct method,
Make hollowing exposure using the method that surface breakdown is taken in the hollowing region that indirect method determines, and then determine hollowing location and range,
But trivial operations and damaged structure.
Infrared thermal imaging technique be it is a kind of the infrared ray that object issues is captured using infrared thermal imaging device, and by heat distribution
Method that is field visualized, being analyzed is a kind of non-contacting lossless detection method.One important parameter of thermal imaging system is heat
The minimum distinguishable temperature of sensitivity, i.e. instrument.As long as the temperature field of body surface is uneven, and the temperature difference is more than the heat of thermal imaging system
Sensitivity can be captured and draw.Sometimes it is unobvious to be visited side object surface temperature difference, it is necessary to which actively heating is be easier to result
In differentiation.
