The invention discloses a cable-stayed bridge tower cable tube positioning measurement device and a measurement method thereof, and relates to the field of cable sleeve positioning measurement. The device comprises a total station, an instrument fine tuning device, a total station stand and a transparent cylinder, wherein the total station is put on the instrument fine tuning device; the instrument fine tuning device is put on the total station stand; the transparent cylinder is put in a cable tube; concentric circle marks are arranged on the top plate and the bottom plate of the transparent cylinder; and the instrument fine tuning device is used for realizing height precision alignment on the total station by adjusting the total station. The cable tube positioning measurement device and measurement method have the characteristics of visualization, no prism and one person measurement, the deviating situation of the cable tube can be intuitively observed, constructors are prompted to quickly and precisely position the cable tube, the source of prism placement centering errors can be eliminated, and the measurement accuracy and construction efficiency can be greatly improved.
Description
technical field [0001] The invention relates to the field of cable guide positioning measurement, in particular to a cable-stayed bridge tower column cableway tube positioning measuring device and a measuring method thereof, which are suitable for the positioning process of cable-stayed bridge tower column cableway tubes for the inclination and the cableway tube Precise measurement of inclination direction is a device and technology that identifies the theoretical axis and actual axis of the measured object and quickly and accurately measures its inclination and inclination direction. Background technique [0002] Cableway tube positioning measurement is an important link related to the construction quality of the cable-stayed bridge tower column. The cableway tube positioning accuracy and positioning speed are the key to the safety and normal construction of the main tower construction structure. Among them, the cableway tube inclination is the most demanding cable-stayed br...
