Description

Technical Field

[0001] The utility model relates to the field of precise positioning of cable-stayed bridge cable conduits, and more specifically, to a precise positioning device for cable-stayed bridge cable conduits. Background Art

[0002] As the main load-bearing tension member, the cable guide positioning and installation is the key process of the cable construction, which has the characteristics of high precision requirements and great construction difficulty. However, there are many factors affecting the positioning of the cable guide, including processing errors, measurement errors, inaccurate positioning, temperature stress, etc., which will have a great impact on the positioning. The accuracy of the cable guide positioning will directly affect the installation quality of the cable. If the deviation is large, the cable will have a fold after installation, which will have a serious impact on the service life of the cable. Therefore, when manufacturing and installing the cable guide, the cable guide accuracy control must be highly valued.

[0003] Because the cable guide is installed after the rigid frame and steel bar engineering are installed, and the main tower is the main load-bearing component, the steel bars are relatively dense. In the positioning of the cable guide, there will inevitably be obstructions such as steel bars, which will block the line of sight and make it difficult to accurately measure and set up. The difficulty and high precision of the cable guide positioning of the cable-stayed bridge has become a major problem in the construction of cable-stayed bridge projects. Utility Model Content
