基于无损电阻法的灌浆套筒缺陷检测研究
Study of Grout Defects Detection Based on Non-Destructive Resistance Method
摘要
Abstract
Grout sleeve connection is widely used as a main connection form in connection nodes of prefabricated concrete structure.The quality of grouting seriously affects the construction quality and structural safety of prefabricated concrete structure.In this paper,a non-destructive resistance method is proposed to detect grouting defects based on the conductivity of grouting materials.Different grouting defect sleeve specimens were designed for a test of non-destructive resistance method detection.The resistance growth rate-time curves were obtained in the final test.The sleeve specimens were analyzed.The resistivity-time linear regression equation was fitted,and the theoretical value of the sleeve resistance was calculated for comparison with the test results.Finally,the experimental and theoretical results are compared and analyzed to judge the accuracy of applying non-destructive resistance method to detect grouting defects and the accuracy of the proposed regression equation.The results show that using the non-destructive resistance method to detect the grouting sleeve specimens has better results,and the detection accuracy of the upper defective specimens can reach 100%.In addition,the test measurement curve is within the theoretical calculation range,indicating that the regression formula is fitted with the prediction and the accuracy of the sleeve resistance value is high,which provides a theoretical basis for the grouting material resistance.关键词
