Five factors of thickness degree obtain measuring point reinforcement corrosion current potential and concrete resistivity by look-up table or interpolation calculation method to sentence
Whether disconnected reinforcing bar corrodes and rate of corrosion, but actually this method still needs to excavate and dig, and need to pick and dig out in concrete
Reinforcing bar, reinforcing bar is connected with conducting wire with detector then and is detected.It is difficult to excavate or inconvenient excavation construction for some
Operating condition be also difficult to apply to this method.A kind of online Corrosion monitoring of armored concrete is invented in addition there are Dong Zehua et al.
Instrument and method, This invention provides a kind of high-precision steel reinforced concrete erosion detection methods based on self-adaptive current constraint, lead to
The additional potential difference between increased two reference electrodes RE2, RE3 of monitoring is crossed, the feedback factor in restriction of current circuit is carried out
Adaptive adjustment makes the power line of polarization current accurately be limited in auxiliary electrode to realize the exact constraint of polarization loop current
In the region of perspective plane, solves measurement error caused by ring protectiving electrode is constrained to auxiliary electrode polarization current or underconstrained.
It is more accurate compared with ring protectiving electrode steel bar corrosion detection method.But the method does not refer to the detection to underground concrete reinforcing steel,
And the standard that only one factor of electricity consumption potential difference is corroded as evaluation, come without the factors of combined influence reinforcement corrosion
Provide conclusion.
