The invention belongs to the technical field of submarine cable laying, and provides a laying construction method and system for a submarine cable to pass through an ultra-long shoal, and the technical scheme is as follows: starting a submarine cable laying ship, and after the submarine cable laying ship reaches a set position, carrying out floating dragging on the submarine cable by means of a winch based on a dragging platform and a buoy until the submarine cable is dragged to a directional drilling position of a landing point; after the submarine cables are dragged in place, cable buoys in the pre-excavated river channel are removed, piles are driven at the inflection points to serve as the inflection points to fix the submarine cables and cannot move, the submarine cables at the pre-excavated river channel are subjected to ditching and burying through an amphibious ditcher, the submarine cables exposed at the non-ditching position of the offshore section are subjected to post-ditching and burying, and the
