Anti-scouring reinforcing structure for underwater pier of existing railway

The utility model relates to the technical field of railway bridges, in particular to an existing railway underwater pier anti-scouring reinforcing structure which comprises steel sheet piles, the steel sheet piles are arranged on the peripheries of a pile foundation and a bearing platform in a surrounding mode, and the tops of the steel sheet piles are encapsulated through underwater concrete to form an integral structure. The underwater concrete is arranged on the periphery of the bearing platform in a surrounding mode. The anti-scouring device has the advantages that the anti-scouring problem that the bottom of a planned river channel is lower than the top of the bearing platform of the existing railway can be solved, the bearing platform and the pile foundation of the underwater pier of the existing railway are effectively protected, and the structural performance of the underwater pier of the existing railway is guaranteed; the construction is convenient, fast, safe and efficient, and the influence on th
