Underwater bridge pier detection device and method thereof

Abstract

The invention provides an underwater bridge pier detection device and method thereof. The device is applied to a bridge pier. The device comprises an overwater frame and an underwater frame which are oppositely arranged on the periphery of the bridge pier, and a movable guide rod assembly and a lifting traction piece which are arranged between the two frames; annular driving pieces are arranged at the opposite ends of the overwater frame and the underwater frame correspondingly, the upper end and the lower end of the movable guide rod assembly are in transmission connection with the two annular driving pieces correspondingly and used for driving the movable guide rod assembly to rotate around the periphery of a pier, and the upper end and the lower end of the lifting traction piece are connected with the overwater frame and the underwater frame correspondingly for pulling the underwater frame to lift. The device also comprises a detection trolley which is arranged on the movable guide rod assembly in a sleeving mode and moves up and down, and the detection trolley is used for detecting the diseased part of the bridge pier. The device is suitable for piers in various shapes, can continuously scan the complete surface of the pier, and is high in working efficiency.

Description

technical field [0001] The invention relates to the field of bridge detection equipment, in particular to an underwater bridge pier detection device and method. Background technique [0002] In underwater terrain surveying, underwater building damage detection and underwater natural slope deformation monitoring projects, since the attenuation of sound waves propagating in water is very small, sonar surveying and mapping is usually used. Acoustic conversion and information processing, complete underwater detection, underwater detection is mainly active sonar, which emits some form of acoustic signal, and uses the echo reflected by obstacles or targets during the underwater propagation of the signal to detect. [0003] At present, underwater sonar is used to detect the appearance of pier columns in the underwater part of bridge piers, but underwater sonar detection can only be carried out by soft rope traction or manual manipulation of hard rods for underwater detection. This...
