Study on Precision measurement technique for Cableway Tube of High Tower Column

摘要

In cableway tube of cable-stayed bridge construction, the precise location and loft cableway be installation accuracy an important part of construction. How fast, accurate the cableway tube precision positioning is the key to the construction of cable-stayed bridge tower column. In this paper, the actual project as an example, Creatively put forward based on the space linear equation and the method of measuring the elevation of Resemble-leveling method, Coordinates measured coordinates with the theoretical calculation coordinates difference. Through the cableway tube naturalization adjust, coordinate difference is zero, To determine the location of the installation of cableway tube. Thereby cableway tube positioning precision and speed of construction to improve.
