【 摘 要 】

Since the underwater docking construction of submerged floating tunnels is difficult because of many disturbance factors such as ocean currents and waves, an auxiliary structure system for the underwater docking installation of floating tunnels is designed in this paper. This system consists of a cylindrical steel truss, a vertical and horizontal mobile mechanism, a clamping structure, an auxiliary position monitoring device and so on, realizing the accurate underwater docking of floating tunnel tubes. In addition, this paper gives an underwater docking construction process of floating tunnel tubes. The technical solution to the underwater docking installation of submerged floating tunnels in this paper has important reference value for the research and construction of the floating tunnel structure.
