The bridge support is an important member for connecting an upper structure and a lower structure of a bridge, and can reliably transmit the reaction force and the deformation of the upper structure of the bridge to the lower structure of the bridge. The bearing is also an important component in bridge detection, and the following six types of diseases of the bearing are required to be detected according to the regulation in the technical standard for urban bridge maintenance: whether a support bolt is damaged, whether a rubber support is deformed, whether a steel support is damaged, whether concrete of a support bottom plate is damaged, whether the support bottom plate is loosened and hollowed or whether the support bottom plate has the danger of beam falling or not, and whether a steel base plate is corroded. The existing support disease detection method generally comprises manual detection and instrument auxiliary detection.
In the aspect of manual detection, the inspector climbs beside the support by taking a ladder under the condition of assistance of other people and observes the disease condition of the support by naked eyes. The method is only suitable for the condition that the supports are not very high and the ladder is erected at the position under the bridge, is complicated to operate, and needs to be erected once when detecting one support, takes time for a long time and needs at least two persons. When the support is very high or under a bridge, a river and the like, manual detection cannot be realized.
In the aspect of instrument-assisted detection, two types of instruments exist at present. The first type is an ascending type camera shooting instrument, wherein a detector raises the camera shooting instrument to a horizontal plane with the same height as a support by using a lifting system from the lower part of a bridge, or lowers the camera shooting instrument to a horizontal plane with the same height as the support by using the lifting system on a bridge floor, and the disease condition of the support is observed remotely by using the camera shooting instrument. The method needs to lift or lower the camera, and the camera is heavy, so that the requirements on the rigidity and the strength of a lifting system are high, the manufacturing cost is high, the camera is expensive, the camera is easy to damage when lifted, and the camera is difficult to maintain. The second type is a periscope type observer, and CN205862003U discloses a periscope type support disease observer, which is mainly used for detecting diseases in the manufacture of small-span bridges, and solves the problem that the support disease cannot be seen by an inspector due to a small clearance height, but cannot solve the problems that the support is too high or rivers, rivers and the like are under the bridge.
