Abstract

Abstract: In the process of sinking and docking construction of sunk pipe joint, the relative geometric position of measuring tower and pipe joint changes slightly due to the deformation of pipe joint body, thus affecting the positioning accuracy of sunk pipe installation. The inclination meter monitoring equipment is installed on the pipe joint body and the measuring tower structure respectively to calibrate the inclination meter installed in the pipe joint under the same coordinate system. In the process of sinking pipe docking, the positioning inclination error of the measuring tower is monitored and corrected in real time. Through comparison and verification, the method can effectively reduce the influence of pipe joint deformation on the positioning accuracy of sinking pipe installation, and obtain good application results, which can provide reference for the construction decision of sinking butt.

Key words: immersed tube installation, measuring tower method, steel shell immersed tube, inclination error
