Description

TECHNICAL FIELD

[0001] The utility model belongs to concrete detection equipment technical field, concretely relates to a concrete durability detection device. BACKGROUND

[0002] As one of the most commonly used building materials in modern construction, the durability of concrete is directly related to the safety and service life of the building. However, in actual engineering, concrete structures often face problems such as water seepage, freeze-thaw, chemical corrosion, etc. Especially in high-rise buildings, the durability of concrete is more prominent. At present, the concrete durability detection technology has the following limitations:

[0003] 1. Single detection method: Traditional detection methods usually use the overall immersion method, that is, the concrete test piece is completely immersed in water for water seepage performance test. This method cannot simulate the actual situation of single-side water seepage of concrete in high-rise buildings, resulting in inconsistent detection results with actual engineering

[0004] 2. Ignoring the influence of temperature difference: Due to the height difference of high-rise buildings, the temperature difference between inside and outside is large. This temperature difference will cause stress changes in the concrete, which will further affect its water seepage performance. The traditional detection method does not consider the influence of temperature difference on the durability of concrete, resulting in inaccurate detection results.

[0005] 3. Low detection efficiency: Existing detection equipment can only test under single environmental conditions and cannot simultaneously simulate multiple complex environmental factors (such as water seepage, temperature difference, freeze-thaw, etc.), resulting in low detection efficiency.

[0006] TECHNICAL PROBLEM

[0007] In view of the above background, the following problems need to be solved in the prior art:

[0008] 1. Unable to simulate single-side water seepage environment: The traditional overall immersion method cannot accurately simulate the actual situation of single-side water seepage of concrete in high-rise buildings, resulting in inconsistent detection results with actual engineering.

[0009] 2. Not considering the influence of temperature difference: The influence of temperature difference between inside and outside of high-rise buildings on the water seepage performance of concrete is not included in the detection range, resulting in lack of scientificity and practicality of the detection results.

[0010] 3. Single detection environment: Existing detection equipment cannot simultaneously simulate multiple complex environmental factors, making it difficult to comprehensively evaluate the durability of concrete. UTILITY MODEL CONTENT
