IMMERSED TUBE CAPABLE OF REDUCING WEIGHT OF REINFORCED CONCRETE

The present invention relates to an immersed tube capable of reducing weight of reinforced concrete, comprising a body. The reinforced concrete of the body is internally provided with a weight reducing component; the weight reducing component is provided with a cavity; the cavity is used for pouring concrete. The weight reducing component is arranged in the body of the immersed tube, and the weight reducing component reduces the weight of the immersed tube by means of the cavity, so that the immersed tube needs a shallower draft during floating transportation, floating transportation of the immersed tube is easier, and the safety of floating transportation of the immersed tube is improved; moreover, excavation deepening of a river below the floating transportation route of the immersed tube can be reduced, and engineering investment can be saved. Additionally, concrete can be poured into the cavity after the floating transportation of the immersed tube is completed or the immersed tube is transported to a mid
