Subdivision positioning structure suitable for large-diameter embedded steel pipe sinking pipe

A subdivision positioning structure suitable for large-diameter embedded steel pipe sinking comprises an embedded steel pipe, blind flanges are arranged at the two ends of the embedded steel pipe, a partition plate is arranged in the embedded steel pipe and divides the interior of the embedded steel pipe, a water injection valve is connected to the lower end of a middle cabin body, an exhaust valve is connected to the upper end of the middle cabin body, and cabin bodies at the two ends are kept vacant. According to the utility model, the interior of the pre-embedded steel pipe is divided into compartments, so that the volume of discharged water can be uniformly adjusted, and the buoyancy can be controlled; the cabins at the two ends are not injected with water, the middle cabin is uniformly injected with water, the structure is prevented from overturning under the action of interference force, the floating stability of the whole structure is not lost due to the influence of an external water area, and finally
