Long-distance underwater transportation method for immersed tube
The invention discloses a long-distance underwater transportation method for an immersed tube. The long-distance underwater transportation method comprises the steps that S1, preparation work before entering water is carried out after immersed tube sections are prefabricated; s2, water is injected into the dock, the immersed tube floats under the action of buoyancy, and the immersed tube is undocked; s3, the towing barge tows the immersed tube to carry out floating transportation in the shallow sea area along the navigation channel; s4, after the towing barge tows the immersed tube into the deep sea area, the immersed tube is towed to the installation position; s5, before the immersed tube enters the mounting position, the immersed tube floats upwards, and after the immersed tube floats upwards, freeboard height adjustment and towing cable adjustment are conducted; and S6, the towing barge tows the immersed tube to float to a designated installation position along the channel, and mooring is carried out after basic positioning. By means of the mode that the immersed tube sections dive to be transported underwater, damage of deep sea extreme environment loads to the structure in the transportation process is avoided, long-distance transportation of the immersed tube crossing the deep sea area is achieved, the built immersed tube tunnel prefabrication factory can be repeatedly utilized, new project investment is saved, and the construction period of a prefabrication site is shortened.
一种沉管的长距离水下运输方法，其步骤为：S1.沉管节段预制完成后进行下水前准备工作；S2.船坞内注水，沉管受浮力作用起浮，完成沉管出坞；S3.拖航驳船拖带沉管在浅水海域沿航道进行浮运；S4.拖航驳船拖带沉管进入深海区域后，将沉管拖航至安装位置；S5.沉管在进入安装位置前，沉管进行上浮，沉管上浮后进行干舷高度调整和拖航缆绳调整；S6.拖航驳船拖带沉管沿航道浮运至指定安装位置，基本定位后进行系泊。本发明通过沉管节段下潜至水下运输的方式避免了在运输过程中深海极端环境荷载对结构的破坏，实现了沉管跨越深海区域的远距离运输，本发明实现了能够重复利用已建的沉管隧道预制工厂，节约了新项目投资和预制场建设工期。
