Curve section large-curvature immersed tube installation process
The invention relates to the technical field of immersed tube installation, in particular to an installation technology of a curved section large-curvature immersed tube. Comprising an immersed tube floating transportation process and an immersed tube sinking process. The floating transportation process of the immersed tube is carried out by seven full-rotation towing wheels, and in the floating transportation process of the immersed tube, the first full-rotation towing wheel and the second full-rotation towing wheel provide power for advancing and braking of the immersed tube; the axis position of the immersed tube is adjusted by the first full-rotation side-towing towing wheel, the second full-rotation side-towing towing wheel, the third full-rotation side-towing towing wheel and the fourth full-rotation side-towing towing wheel through a bullet train, so that the immersed tube does not deviate from a floating transportation channel; after the immersed tube is conveyed in place in a floating mode, the immersed tube is immersed so that the immersed tube can be implanted; according to the installation process of the curved-section large-curvature immersed tube, the number of tugs needed for floating transportation is reduced, and the cost is reduced; the sinking position of the immersed tube is close to the tail end of the installed immersed tube, the pulling and closing distance after implantation is small, the axis offset of the tail end of the immersed tube is small, and the axis deviation of the tail end of the immersed tube can be controlled easily.
本发明涉及沉管安装技术领域，尤其涉及一种曲线段大曲率沉管的安装工艺；包括沉管浮运过程以及沉管沉放过程；所述沉管的浮运过程由七艘全回转拖轮进行，沉管浮运过程中，第一全回转吊拖拖轮、所述第二全回转吊拖拖轮提供沉管前进与制动的动力，第一全回转傍拖拖轮、第二全回转傍拖拖轮、第三全回转傍拖拖轮、第四全回转傍拖拖轮通过动车调整所述沉管轴线位置使所述沉管不偏离浮运航道；当所述沉管浮运到位后，进行沉放使得所述沉管着床；本发明的曲线段大曲率沉管的安装工艺，浮运所需拖轮数量减少，成本降低；沉管沉放位置距离已安装沉管的尾端近，着床后拉合的距离小，沉管尾端轴线偏移量小，有利于控制沉管尾端轴线偏差。
