Title:
METHOD FOR INSPECTING STATE OF STEEL BAR IN CONCRETE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/143281
Kind Code:
A1
Abstract:
A method for inspecting the state of a steel bar in a concrete structure, comprising according to capacitance value data and the area of a capacitance peak which are acquired by scanning a steel bar concrete member, establishing representation mapping between the two and a steel bar state; performing scanning inspection on concrete members of different specifications; establishing a correlation between an inspection position and a capacitance value obtained by scanning inspection, and acquiring, in conjunction with the representation mapping, the position of a steel bar, the size of the steel bar and the thickness of a protective layer of the steel bar of the concrete members. The present invention performs targeted inspection on the steel bar in concrete, and uses the representation mapping and the correlation thereof to conveniently acquire a more accurate result comprising the position of a steel bar, the size of the steel bar and the thickness of a protective layer of the steel bar, thereby improving the working efficiency of construction project acceptance and the inspection, reinforcement and identification of an existing steel bar concrete structure.
