Disclosed is an underground concrete structure steel corrosion nondestructive diagnosis device, which belongs to the technical field of underground structure overhaul and maintenance. It includes: mode conversion module, Cl ‑ The mass percentage detection device, pH detection device, O 2 The volume percentage detection device, the actual corrosion percentage acquisition module, the analog-to-digital converter, the data acquisition module, the standard curve drawing module, the first data fitting module, the second data fitting module, and the corrosion percentage conversion module. Among them, in the function fitting mode, the necessary condition for the standard curve drawing module to draw the standard curve is that the actual corrosion percentage, Cl ‑ The mass percentage, pH and O 2 The data combination composed of volume percentage content involves at least 5 detection points. The diagnosis process using the device is simple and the result is accurate.
Description
technical field [0001] The invention relates to the technical field of overhaul and maintenance of underground structures, in particular to a non-destructive diagnosis device for steel corrosion of underground concrete structures. Background technique [0002] The underground foundation structure is the main bearing body of the upper structure, which needs to bear the self-weight load, wind load, and other environmental loads transmitted by the upper structure. In addition, the geological environment, natural environment and other unfavorable factors such as changes, its safety performance is directly related to the upper structure. structural safety. The underground structure is a concealed project, and its integrity cannot be checked daily like the above-ground structure. It is even more difficult to obtain accurate data on the corrosion rate of steel bars inside the underground structure. For the concealed structure of the transmission tower foundation, if various factor...
