A device and method for in-situ monitoring of reinforced concrete reinforcement

Abstract

The invention discloses an in-situ monitoring device and method for reinforced concrete steel bars. The device includes a standard steel bar test block, an electromagnetic eddy current detection sensor, an electrochemical corrosion detection sensor, an integrated detection instrument for electromagnetic eddy current and electrochemical corrosion, a wireless signal transmission device, and a magnetic induction sensor. Type charging power supply, electromagnetic eddy current and electrochemical corrosion remote data analysis system, the monitoring device is pre-buried in the inspected reinforced concrete, the monitoring device is in the same ecological environment as the inspected reinforced concrete, and adopts wireless signal transmission and wireless charging methods, Through the integrated monitoring method of electromagnetic eddy current and electrochemical, the remote and long-term in-situ monitoring of the corrosion and thinning degree of steel bars in reinforced concrete can be realized. The integrated monitoring of electromagnetic eddy current and electrochemical can further predict the service life of the steel bars under inspection.

Description

Technical field [0001] The invention relates to a reinforced concrete monitoring device and method, in particular to an in-situ monitoring device and method for the corrosion and thinning degree of steel bars in reinforced concrete. Background technique [0002] Reinforced concrete is a composite material formed by adding steel mesh, steel plates or fibers to concrete. It is the core material of major facilities such as buildings, bridges, and tunnels. During the use of reinforced concrete, affected by the environment and climate, the steel bars in the concrete are prone to corrosion. Under long-term corrosion, the steel bars will be thinned and fractured, and then the concrete will break and collapse. At present, for the detection of steel bar corrosion in reinforced concrete, manual periodic sampling is usually used for detection. For large-scale reinforced concrete facilities, the detection efficiency is low and missed inspections are prone to occur. Contents of the inv...

Problems solved by technology

During the use of reinforced concrete, affected by the environment and climate, the steel bars in the concrete are prone to corrosion. Under long-term corrosion, the steel bars will be thinned and fractured, and then the concrete will break and collapse.

At present, for the detection of steel bar corrosion in reinforced concrete, manual periodic sampling is usually used for detection. For large-scale reinforced concrete facilities, the detection efficiency is low and it is easy to miss detection.
