Description

Technical Field

[0001] The utility model relates to the technical field of bridge manufacturing, in particular to the technical field of bridge arch rib cable processing length measurement. Background Art

[0002] A bridge is a structure built for roads to cross natural or artificial obstacles. According to the force characteristics, bridges are divided into five basic types: beam bridges, arch bridges, steel frame bridges, suspension bridges and combined system bridges (cable-stayed bridges).

[0003] Bridge cable is a new type of bridge material and a bridge suspension device, mainly composed of steel hangers, steel cables, anchor heads, and nuts. It often exists in the form of rods or cables, and its main function is to withstand the tension of several structures in bridge engineering. When in use, one end of the bridge cable is fixed to the bridge arch or bridge tower through a nut, and the other end is also connected to the beam through a nut. Its connection with the arch bridge, bridge tower, and beam is a rigid connection.

[0004] In the related technology, laser distance measurement technology and total station measurement technology are generally used to measure the distance between the actual anchor point and the lower anchor point, and the processing length of the arch rib cable is directly determined by this. The related technical measurement must ensure that there is no visual obstruction between the upper and lower anchor points of the arch rib cable. If the anchor point is located inside the arch rib box or other situations, it is impossible to achieve distance measurement through laser distance measurement, total station and other methods.
