[0022] Bridge expansion joint is an important part of bridge structure, which is used to adjust the deformation gap of the bridge. Its main function is to adapt to the deformation of the bridge caused by temperature changes, concrete shrinkage and live load. Bridge expansion joint has certain flexibility, which can ensure that the bridge does not produce excessive stress during deformation, thereby ensuring the safety of the bridge structure. Expansion joint can reduce the influence of bridge deformation on vehicle driving and improve driving comfort. It can prevent damage to the internal structure of the bridge caused by dust, water vapor and other factors, and prolong the service life of the bridge. Expansion joint allows the superstructure of the bridge to change temperature and settle when affected by physical factors. Expansion joint can have certain expansion displacement, so that the bridge will not damage the attached components during deformation, ensuring the safe operation of the bridge. During the long-term use of expansion joint, it needs to be regularly inspected for its appearance, to check whether the rubber sealing strip is intact, damaged or fallen off, to check whether the profile steel is deformed or rusted, and to clean the debris such as stones and soil in the expansion joint in time. These debris may affect the expansion function of the expansion joint, and even damage the rubber sealing strip and profile steel.
