The invention relates to a floating assisting structure for reducing the immersion depth of an immersed tube section and a mounting method of the floating assisting structure. A floating assisting structure for reducing the immersion depth of an immersed tube section comprises floating boxes which are located on the two sides and symmetrically arranged, and the floating boxes on the two sides are connected through a bottom support. Under the action of buoyancy of the buoyancy boxes on the two sides, the bottom support can upwards support the immersed tube joint, and then the immersed tube joint can absorb water shallower in the floating transportation process, so that the excavation depth of a long-distance shallow narrow channel can be reduced, the engineering quantity is smaller, the construction period is short, and the cost is lower; and the influence of channel excavation on existing buildings can be reduced, and the influence on the ecological environment in the channel range is smaller. The stranding risk of passing the immersed tube section while the water is moist in the window period is smaller, and the immersed tube section does not need to pass the immersed tube section while the water is moist in the window period in some places where the water depth meets the requirement, so that the conditions of floating transportation of the immersed tube section are easier to meet.

    本发明涉及一种降低沉管管节吃水深度的助浮结构及其安装方法。一种降低沉管管节吃水深度的助浮结构,包括位于两侧且对称设置的浮箱,两侧的所述浮箱通过底托连接。其在两侧的所述浮箱的浮力作用下,底托能够向上托起沉管管节,进而使得沉管管节在浮运过程中能够吃水更浅,沉管管节吃水更浅,故能够降低长距离浅窄航道的开挖深度,工程量更小、工期小、费用更低;且能够降低开挖航道对既有建构筑物的影响,对航道范围内的生态环境的影响更小。且在窗口期趁潮通行的搁浅风险更小,而且在某些水深满足需求的地方,甚至无需在窗口期趁潮通行,使得浮运沉管管节的条件更容易满足。
