The utility model discloses a movable docking bridge loading by blowing barge platform which comprises a grab bucket boat, a pipeline device for conveying dredging soil, a support and a control device for controlling height of an energy dissipation nozzle. An anchor gear is fixed on the grab bucket and connected with an anchor through an anchor cable. A water borne floating barrel pipe, a flexible connection self-floating pipe and a platform steel pipe are sequentially connected and compose the pipeline device for conveying the dredging soil. The platform steel pipe is arranged above the grab bucket boat and a free end of the platform steel pipe stretches out of the grab bucket boat. The energy dissipation nozzle is fixed on the free end of the platform steel pipe. The support is connected on a deck of the grab bucket boat in welded mode. The platform steel pipe is supported on the support. The control device for controlling the height of the energy dissipation nozzle comprises a lifting machine, a lifting support and a steel wire cable. The movable docking bridge loading by blowing barge platform moves synchronously with a mud barge, the pipeline device and a cutter suction dredger so that production efficiency is greatly improved. As the needed pipeline is short, loading by blowing power of the cutter suction dredger is not required to be large and energy consumption and cost in construction are saved.
