Viaduct safety monitoring and guaranteeing device

The invention provides a viaduct safety monitoring and guaranteeing device. The viaduct safety monitoring and guaranteeing device comprises a deceleration strip, a deceleration buffer area and a visual detection area. A viaduct body is erected above viaduct piers; the deceleration buffer area is located on the viaduct body, and the deceleration strip is laid in the deceleration buffer area; the visual detection area is located behind the deceleration buffer area, and a first weight detection feedback area is located behind the visual detection area; a strain gauge pressure sensor is embedded in the road surface of the first weight detection feedback area; and a ramp is located behind the first weight detection feedback area. By improving the viaduct safety monitoring and guaranteeing device, the viaduct safety monitoring and guaranteeing device has the advantages of being reasonable in design, capable of detecting and judging whether a vehicle is overloaded or not and detecting and judging whether a driver is
