Abstract

The invention relates to the technical field of concrete structure detection and identification, and discloses a steel bar scanning and concrete protection layer thickness detection method, which comprises the following steps of S1, determining a detection region: obtaining the position of a region to be detected according to the detection requirement, and cleaning the position of the region to bedetected in advance; s2, building modeling: obtaining a building drawing, performing local three-dimensional modeling according to information in the building drawing, and making and displaying a building model of a to-be-detected area through three-dimensional software; s3, determining the position of the reinforcing steel bar: preheating and zeroing the reinforcing steel bar detector, and irregularly moving a probe of the reinforcing steel bar detector on the surface of the building to be detected until the instrument displays and receives a signal. The reinforcing steel bar scanning and concrete protection layer thickness detection method can solve the problem that when the diameter of the reinforcing steel bar and the thickness of the protection layer are detected at present, the detection result error is large.

Description

technical field [0001] The invention relates to the technical field of concrete structure detection and appraisal, in particular to a steel bar scanning and concrete protective layer thickness detection method. Background technique [0002] At present, the detection technologies for concrete structures in construction projects include traditional destructive detection methods and new non-destructive detection methods. It is easy to miss bad sections, internal hidden dangers cannot be checked, and it is destructive. Therefore, the importance of non-destructive testing technology as an analysis method for quality control in engineering construction and post-disaster structural safety assessment has become increasingly apparent. Commonly used non-destructive testing techniques mainly include rebound method, ultrasonic rebound comprehensive method, infrared method, ray detection method, electromagnetic induction method, ground penetrating radar method, eddy current detection, e...
