Aiming at the practical problems that the thickness of reinforced concrete protective layer of the component is difficult to accurately detect,a set of environmental calibration test device was developed.Study was carried out on the detection technology of the thickness of the reinforced concrete protective layer of the component.In this paper,the influence of testing instruments,steel bar types,steel bar spacing,steel bar layers and testing speed on the testing results was studied.A set of reasonable,perfect and applicable methods and calibration procedures were formed for the detection of the thickness of reinforced concrete protective layer in highway and water transportation engineering.The results showed that engineering application could effectively improve the detection accuracy of the thickness of the protective layer of the reinforced concrete,which can save the production of calibration standard test piece.
