Immersed tunnel full-floating type foundation bed leveling method

The invention belongs to the technical field of immersed tube tunnel foundation bed leveling, and particularly relates to an immersed tube tunnel full-floating type foundation bed leveling method. The foundation bed leveling method does not comprise the pile inserting step, and the leveling ship drives the riprap pipe to conduct foundation bed laying and leveling operation by moving the walking cart and the walking trolley in the full-floating state. In the operation process, the numerical value of the clinometer of the ship body is read in real time, and the ballast water amount of each ballast tank on the leveling ship is adjusted in real time according to the numerical value, so that the leveling ship is kept horizontal all the time in the operation process. According to the immersed tube tunnel full-floating type foundation bed leveling method, the problems that under the complex geological condition, a traditional full-lifting type foundation bed leveling method is large in pile inserting risk, foundatio
