Multifunctional monitoring device for corrosion damage of underground concrete structure

Abstract

The invention discloses a multifunctional monitoring device for corrosion damage of an underground concrete structure, and relates to the field of civil engineering monitoring devices. The multifunctional monitoring device for corrosion damage of the underground concrete structure is suitable for being connected with a steel bar of the underground concrete structure, and comprises a monitoring system, a wireless transmission device and a fixing mechanism. The monitoring system comprises strain sensors, a temperature sensor and PH value monitoring equipment, wherein the strain sensors, the temperature sensor and the PH value monitoring equipment are connected with the steel bar through the fixing mechanism and further connected with the wireless transmission device. Multifunctional monitoring of corrosion damage of the underground concrete structure is achieved by arranging the strain sensors, the temperature sensor and the PH value monitoring equipment, signals collected by the strain sensors, the temperature sensor and the PH value monitoring equipment are transmitted to an operation interface through the wireless transmission device, and monitoring personnel can observe the corrosion damage condition conveniently in real time. The device is small in size, and the monitoring system has few influences on the structure.

Description

technical field [0001] The invention relates to the field of civil engineering monitoring devices, in particular to a multifunctional underground concrete structure corrosion damage monitoring device. Background technique [0002] The environment of underground building structures is relatively complex, which is often affected by load, corrosion, environmental medium erosion, carbonization, steel corrosion, freeze-thaw damage, and alkali-aggregate reaction. More and more engineering examples prove that most of these factors will act together to accelerate and intensify the damage process, resulting in premature damage of underground buildings and rapid and serious deterioration of concrete quality, and the construction of projects in underground environments is difficult and emergencies Plenty, and few remedies. After the occurrence of underground structure hazards, the evaluation of the damage degree and remaining life of the structure has attracted more and more attention...

AI Technical Summary

Problems solved by technology

However, due to the limitations of sensor materials, usage methods, information transmission and other factors, and its disadvantages such as moisture, poor durability, etc., it is difficult to be used in highly corrosive underground structures, and real-time and automatic monitoring is also very difficult.
