Immersed tube subsea tunnel semi-floating foundation bed leveling method
The invention relates to the technical field of immersed tube tunnel construction, in particular to an immersed tube subsea tunnel semi-floating foundation bed leveling method. The immersed tube subsea tunnel semi-floating foundation bed leveling method mainly comprises the following steps that (1) positioning is achieved; (2) leveling is achieved; (3) pile insertion is achieved;(4) lifting is achieved; (5) stones are paved on a foundation bed; the immersed tube subsea tunnel semi-floating foundation bed leveling method is suitable for complex geological conditions where pile insertion cannot be carried out, pile legs of a leveling ship do not need to be completely inserted into rock and only need to be inserted into the allowable stress range of the pile legs, the leveling ship is in a semi-floating state, the risk of pile insertion is greatly reduced, and a certain guarantee is provided for safety during construction of the leveling ship; and the construction height of the leveling ship is set, so that the influence of tidewater and waves on the construction precision can be avoided.
本发明涉及沉管隧道施工技术领域，尤其涉及一种沉管海底隧道半漂浮基床整平方法。主要包括如下步骤：(1)定位；(2)调平；(3)插桩；(4)抬升；(5)基床铺设石料；适用于无法进行插桩的复杂地质条件，无需将整平船的桩腿全插入岩石内，只需将桩腿插入至其受力允许范围，使整平船处于半漂浮状态，极大的降低了插桩的风险，对整平船施工时安全提供一定的保障；整平船的施工高度的设置，可以避免潮水及波浪对施工精度造成影响。
