[0002] Bridges are an important part of transportation infrastructure, and their safe operation is of great significance. However, as bridges age and traffic volumes continue to increase, the safety and durability of bridge structures will be affected to varying degrees. Therefore, carrying out bridge inspections is of great significance to ensuring the safety and durability of bridges. When conducting bridge dynamic inspections, the existing conventional method is to place vibration-sensing sensors on the bridge pavement, which requires traffic interruption or necessary traffic control, resulting in traffic jams, seriously affecting traffic efficiency, and affecting a wide range of areas. In particular, if bridges that serve as important transportation hubs are interrupted, the economic and social impact will be significant. Summary of the Invention

The top plate is vertically connected to the side plates, and the side plates are vertically connected to the bottom plate. The top plate waist hole is located on the top plate, the side plate holes are located on the side plates, and the bottom plate holes are located on the bottom plate. There are four top plate waist holes, which serve as chemical bolt holes for connecting the bottom of the bridge main beam. The waist holes are designed to facilitate the adjustment of the bolt position to avoid the steel bars in the concrete at the bottom of the bridge main beam. The side plate holes are used to connect horizontal sensors, and the bottom plate holes are used to connect vertical sensors. The positions and numbers of the side plate holes and bottom plate holes are determined according to the corresponding specific sensors.

The distance between the top and bottom plates must be determined based on the specific sensor size, taking into account the vertical distance of the sensor signal transmission line. The material and thickness of the top, side, and bottom plates are determined by the specific sensor; 10mm thick Q235 steel is recommended.

[0008] Installation Method: 1. Based on the number, location, and size of the top plate's back holes, arrange a corresponding number of chemical bolt holes in the bridge's bottom plate concrete. The hole depth should be determined according to relevant specifications. Align the top plate back holes of the sensor mounting device with the chemical bolt holes, and use chemical bolts to connect the sensor mounting device to the concrete at the bottom of the bridge beam. 2. If the sensor being installed is a horizontal sensor, align the side bolt holes on the horizontal sensor with the side plate holes of the sensor mounting device, and connect the horizontal sensor to the sensor mounting device with self-tapping screws. 3. If the sensor being installed is a vertical sensor, align the bottom bolt holes on the vertical sensor with the bottom plate holes of the sensor mounting device, and connect the vertical sensor to the sensor mounting device with self-tapping screws.

[0009] Removal method: 1. Remove the sensor by unscrewing the self-tapping screws from the sensor; 2. Unscrew the chemical bolt cap and remove the sensor installation device; 3. Treat the rebar exposed outside the concrete with anti-corrosion treatment or cut it off.
