Curve segment immersed tube ballast attitude control method
The invention relates to a curve segment immersed tube ballast attitude control method, which comprises the following steps of: theoretically calculating the shape of a tube joint to obtain the plane position of the centroid of the tube joint; leveling the pipe joints, wherein the gravity centers and the centroids of the pipe joints are in the same straight line; calculating the shape and position of each water tank to obtain the plane position of the centroid of each water tank, and calculating the stowage ratio of each water tank; carrying out ballasting according to the stowage ratio in the leveled state, and judging whether balance is kept or not; ballasting is carried out according to the accurate stowage ratio of each water tank, so that the gravity center position of the pipe joint and the centroid position of the pipe joint are always kept on the same straight line, and the stable posture of the pipe joint is ensured. According to the method, the shape and the position of the curve section pipe section ballast water tank are calculated, the theoretical proportion of the arc outer side to the arc inner side during curve section pipe section ballast is obtained, the water tank ballast amount is verified in the sinking drilling process, and stowage during formal installation is determined; theoretical calculation and test verification ensure that the pipe joint posture is kept when the curve section pipe joint is formally installed and ballasted.
本发明是一种曲线段沉管压载姿态控制方法，包括：通过对管节形状进行理论计算，求得管节形心的平面位置；把管节调平，管节的重心、形心处于同一直线；再通过对各个水箱的形状、位置计算得出各个水箱形心的平面位置，并计算各个水箱的配载比例；在已经调平的状态下按配载比例进行压载，看是否保持平衡；按照各个水箱准确的配载比例进行压载，使得管节重心位置始终与管节形心位置保持在同一直线上，保证管节姿态稳定。本发明通过对曲线段管节压载水箱形状位置进行计算，得出曲线段管节压载时圆弧外侧与圆弧内侧的理论比例，并在沉放演练过程验证水箱压载量，确定正式安装时配载；通过理论计算与试验验证确保曲线段管节正式安装压载时保持管节姿态。
