Application of Measuring System based on Ship Frame Separation Equipment in Gravel Foundation of Immersed Tunnel by Pre-laying Method
In order to meet the requirements of large surface,deep water depth,high precision and high efficiency,the underwater walking leveling equipment is selected to carry out the leveling operation of the S08 Contract Section of the Shenzhen-Zhongshan Link Project through multi-comparison and selection,and the rectangular shaped ship with the moon pool is used as the working mother ship.The monitoring system of immersed tunnel foundation levelling is used to detect the quality of the levelled gravel cushion in real time.The data are stored in the computer,and the operator can grasp the levelling accuracy in time through the display screen,which realizes the high-precision guidance of the measuring system when the working mother ship is separated from the levelling frame.
