The invention relates to the technical field of floating transportation, in particular to a floating transportation device and a floating transportation method for a shallow water channel large component, the floating transportation device comprises at least two side surface floating boxes which are oppositely arranged, a head floating box and a tail movable floating box are respectively connected between the adjacent side surface floating boxes, and the head floating box and the tail movable floating box are arranged at an interval; a deck is jointly connected to the upper portions of the side buoyancy tanks, the head buoyancy tank and the tail movable buoyancy tank, a sealed cabin with the bottom open is jointly defined by the deck, the head buoyancy tank, the tail movable buoyancy tank and the two adjacent side buoyancy tanks, when the immersed tube transportation device is applied to transportation of large-size immersed tubes, the immersed tubes are placed in the sealed cabin, the sealed cabin is vacuumized through an air extractor, and the immersed tubes can be transported through the sealed cabin. A vacuum area is formed in the sealed cabin, the water surface in the sealed cabin rises under the action of atmospheric pressure, and the immersed tube drifting on the water surface in the cabin is driven to rise together, so that the distance between the immersed tube and the bottom of the shallow water channel is increased, the requirement for the water depth of the shallow water channel is reduced, and the floating operation difficulty is reduced.
本发明涉及浮运技术领域,特别是用于浅水航道大型构件的浮运装置及浮运方法,浮运装置包括至少两个相对设置的侧面浮箱,相邻侧面浮箱之间分别连接有头部浮箱和尾部活动浮箱,头部浮箱和尾部活动浮箱间隔设置,侧面浮箱、头部浮箱和尾部活动浮箱的上方共同连接有甲板,甲板与头部浮箱、尾部活动浮箱和两个相邻侧面浮箱共同围成底部敞口的密封舱,应用到尺寸较大的沉管运输时,将沉管放置在密封舱内,通过抽气装置对密封舱进行抽真空,使密封舱内形成真空区域,在大气压力的作用下使密封舱内的舱内水面上升,带动漂移在舱内水面的沉管一同上升,从而增大了沉管与浅水航道底部的间距,进而减少对浅水航道水深的要求,降低了浮运作业难度。
