摘要: 在沉管管节沉放对接施工过程中,针对管节本体发生形变导致测量塔与管节相对几何位置发生微变,从而影响沉管安装定位精度的问题,本文在管节本体与测量塔结构上分别加装倾斜仪监测设备,与管节内安装的倾斜仪在同一坐标体系下进行标定,在沉管沉放对接过程中实时监测与修正测量塔定位倾斜误差。经贯通测量比对验证发现,该方法可以有效降低管节形变对沉管安装定位精度的影响,取得了良好的应用效果,为沉放对接施工决策提供了参考。

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.
