The invention provides a synchronous and fast construction method and a synchronous and fast construction device for a cantilever-cast continuous girder No.0 block and a lower structure. The construction comprises the following steps of: building a continuous girder No.0 block assembly platform on one side of a centre line of a bridge during pier body construction of the lower structure, and mounting a sliding channel; mounting brackets, templates, steel bars and prestressed pipe bundles for No.0 block construction on the assembly platform; mounting pier-side brackets and sliding channels after the pier body construction is finished, and connecting the sliding channels with the sliding channel of the assembly platform; mounting a No.0 block traction device; wholly sliding and placing the No.0 block templates, steel bars and the like through the traction device; and pouring No.0 block concrete. The invention has the advantages that: various processes are reasonably arranged, the time is saved, and the construc
