1. A semi-submersible immersed tube transportation and installation integrated ship, including:
a deck structure;
two floating structures, ballast water being able to be injected therein; taking a vertical plane where a centerline of the integrated ship along a length direction is located as a reference plane, the two floating structures are symmetrical and parallel to the reference plane, and upper portions or top surfaces of the two floating structures are connected by the deck structure; and
two support mechanisms, disposed on opposite sides of the two floating structures respectively; the two support mechanisms are symmetrical to the reference plane, and each support mechanism is disposed at a lower portion or a bottom of the corresponding floating structure;
wherein, each support mechanism further includes:
at least two support assemblies; and
drive assemblies each configured to drive the support assembly to abut against or stretch out of the floating structure where the support assembly is located; and
the support assemblies are able to support a bottom surface of an immersed tube after stretching out of the floating structures; and a space above the support assemblies, below the deck structure and between the two floating structures constitutes a carrying space for accommodating the immersed tube.
