Problems solved by technology

Due to the high installation accuracy of the tower column and the base, the tower column and the base are constructed by different units, and there will be a large error in the measurement of the tower column and the base during subsequent assembly, which will make the first flange hole at the upper end of the base and the tower column The second flange hole at the lower end deviates, and often needs to be re-cut or adjusted, making assembly difficult and delaying the construction period

Abstract

The invention discloses an assembly method of a measuring tower and a positioning tool applied to the assembly method. During the assembly process of the measuring tower, the three bases are respectively positioned by the three third flanges on the positioning tool. Since the position of the third flange on the positioning tool is fixed, the three flanges on the first flange are fixed. Each first flange hole is directly opposite to each third flange hole in the third flange, and the distance between two adjacent bases fixes the size of the base assembly. In addition, the first method can also The center line of the blue hole coincides with the center line of the third flange hole, which is conducive to the direct alignment of the subsequent second flange hole and the first flange hole. The second flange is placed on the third flange correspondingly. After aligning the second flange hole with the third flange hole, directly weld the tower column to the second flange. The first flange hole and the third flange The holes of the two flanges are facing each other, so that the size of the welded tower assembly matches the size of the base assembly, and the flatness of the end face of the first flange and the end face of the second flange is guaranteed.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to an assembly method and a positioning tool of a measuring tower. Background technique [0002] When the immersed tube tunnel is launched into the water, it is necessary to use the measuring tower to measure parameters such as the attitude and plane position of the pipe joint. The measuring tower generally includes a measuring tower column and a base, the lower end of the base is set on the pipe joint panel, and the measuring tower column is installed on the upper end surface of the base. In the prior art, the tower column and the base are constructed by different construction units. The base is first welded on the pipe joint panel, and then the tower column is installed on the upper end surface of the base when in use. Due to the high installation accuracy of the tower column and the base, the tower column and the base are constructed by different units, and there wil...
