Abstract

The invention relates to a bridge pier safety detection device and a detection method thereof. The problems that an existing bridge pier perpendicularity measuring tool and method are poor in precision, large in difficulty and low in efficiency are effectively solved. According to the technical scheme, the device comprises a horizontal cantilever beam and a vertical laser range finder, the laser range finder slides along the cantilever beam, laser is vertically emitted upwards on one side of a pier through the laser range finder and irradiates the surface of the pier, and the laser, a pier bus and the cantilever beam form a right triangle. The reading of the laser range finder and the distance between the laser range finder and the surface of the bridge pier are the lengths of the two sides of the right triangle, and the inclination of the bridge pier on the side can be obtained by solving the triangle; the measurement object is the whole section of the bridge pier, the measurement precision is high, climbing is not needed, the influence of wind power is avoided, a proper position where the whole bridge pier can be observed does not need to be found, long-distance conversion detection is not needed, the measurement difficulty is greatly reduced, and the measurement efficiency is improved.

Description

technical field [0001] The invention relates to the field of bridge detection equipment, in particular to a bridge pier safety detection device and a detection method thereof. Background technique [0002] As the load-bearing part of the bridge, the verticality of the bridge pier is an extremely important indicator. The inclination of the bridge pier will change the force on the pier, and the pier will bear abnormal tangential force, and the pier will easily crack, break or even collapse. The detection of the verticality of bridge piers is very important work. [0003] At present, the inclination of the bridge pier is mainly measured by the vertical line method, the ruler method, or the total station; the length of the detection section of the vertical line method and the ruler method is limited, and it is generally limited to the lower section of the bridge pier. If you want to use the bridge pier If the full length is used as the detection object, it is necessary to climb...
