Deck supporting device for floating installation of shallow water area platform module

A deck supporting device for floating installation of a shallow water area platform module comprises a sliding way, a sliding shoe, a buffering assembly, a supporting assembly, an inclined strut and the like. The supporting assembly is of a split structure and is formed by connecting a supporting leg and an inserting piece in an adsorption mode through an electromagnetic chuck. The top of the buffering assembly can be in butt joint with the inserting piece. The load of the platform module is transmitted to the barge through the double-conical-surface contact surface when the supporting assembly and the buffering assembly are in butt joint, and the design can provide higher stability for the operation process. In the platform module load transferring process, the buffering assembly further provides necessary buffering, and rigid collision is avoided. In the floating support installation and retreating process, the platform module can be rapidly separated through the split structure of the supporting assembly,
