Embodiment Construction
[0052] As described in the background art, in the prior art, due to the interference of stirrups, the scanning accuracy of reinforced concrete is not high, and the scanning efficiency is low.
[0053] In order to solve the above problems, the embodiment of this application proposes a reinforced concrete scanning method based on electromagnetic induction, which receives derivative signals through multiple sensors, and accurately determines the position of the main reinforcement in the reinforced concrete structure, the diameter of the main reinforcement, the thickness of the protective layer of the main reinforcement and the stirrup. The distribution situation avoids the stirrup interference.
[0054] Such as figure 1 As shown, the schematic flow chart of a method for scanning reinforced concrete based on electromagnetic induction proposed by the present application, which is applied to a scanner with multiple sensors, includes the following steps:
[0055] S101, sending an in...

The invention discloses a reinforced concrete scanning method based on electromagnetic induction and a scanner. The method is applied to a scanner equipped with multiple sensors, and sends out an induced magnetic field to the reinforced concrete; receives signals corresponding to the induced magnetic field. Derivative signal of the derived signal and generate a multi-level signal, wherein the multi-level signal includes a front-level signal, an intermediate-level signal and a rear-level signal; the position of the main tendon is determined according to the mean value of the front-level signal and the mean value of the intermediate-level signal, thereby real-time Accurately locate the position of the main reinforcement in the reinforced concrete structure, avoid the interference of the stirrup, and improve the scanning accuracy and efficiency.
Description
technical field [0001] The invention relates to the technical field of building detection, in particular to an electromagnetic induction-based reinforced concrete scanning method and a scanner. Background technique [0002] Since the strength of concrete has the characteristics of high compressive strength and low tensile strength, while the strength of steel bars has the characteristics of high tensile strength and low compressive strength, the reinforced concrete structure combined with the two can obtain good compressive and tensile strength. At present, it is also a kind of building structure widely used in buildings, bridges, tunnels and other buildings. [0003] The reinforcement ratio and the thickness of the reinforcement cover in the reinforced concrete structure are different, and the ability of the reinforcement to withstand the tensile stress in the specific structure is also correspondingly different. When the thickness is too large, the crack control performan...
