Large immersed tube in-dock steering and turning method
The invention relates to the technical field of immersed tube tunnels, in particular to a large immersed tube in-dock steering and turning method which comprises the following steps: S1, filling water into a dry dock to float a large immersed tube, and carrying out large immersed tube mooring operation; s2, transversely moving the large immersed tube for the first time after the large immersed tube is provided with a cable, and moving the large immersed tube from a shallow dock area to a deep dock area steering position; s3, the large immersed tube is steered and moved at multiple different points in the deep dock area, cable adding, cable replacing and cable untying are carried out, and the turning-around operation of the large immersed tube is completed; and S4, the large immersed tube is transversely moved to the docking axis after turning around. Steering operation of multiple different point positions is carried out in the deep dock area, so that turning around of the large immersed tube in the deep dock area is completed under the condition that the deep dock area does not need to be excavated and enlarged, and the problem that when a conventional dry dock is constructed and designed, enough space is not reserved for the large immersed tube to steer in the dock is solved. And the steering of the large immersed tube in the dock is very difficult.
本发明涉及沉管隧道技术领域，特别涉及大型沉管坞内转向掉头方法，包括以下步骤：S1：向干坞内灌水，使大型沉管起浮，并进行大型沉管带缆作业；S2：大型沉管带缆后第一次横移，从浅坞区移动至深坞区转向位置；S3：大型沉管在深坞区内进行多个不同点位的转向和移动，并进行加缆、换缆和解缆，完成大型沉管的掉头作业；S4：大型沉管掉头后横移至出坞轴线上。通过在深坞区内进行多个不同点位的转向作业，从而实现在不需要对深坞区开挖扩大的情况下，完成大型沉管在深坞区内的掉头，解决了常规干坞在建造设计时没有预留出足够的空间供大型沉管在坞内转向，导致大型沉管在坞内转向极为困难的问题。
