The invention discloses a rolling stone impact resisting device for a pier, based on transformation of worn-out containers. The rolling stone impact resisting device comprises one or more containers of which the tops are removed and fillings, wherein the containers adopt a one-row or multi-row combined structure in manners that side walls of the containers are mutually attached and arrayed, end walls of the containers are mutually attached and arrayed, and the containers are in oblique contact arraying and piling; the combined structure is arranged on one side surface facing rolling stones, ofthe pier; the combined structure and the main attacking direction of rolling stones are mutually perpendicular or obliquely crossed; and each container is filled with the fillings, so that the rolling stone impact resisting device for the pier is formed. The rolling stone impact resisting device disclosed by the invention is formed by simple transformation of the worn-out containers; the construction is simple and convenient; the construction speed is high; a new way for the resource reuse of the worn-out containers is provided; the space volume of the containers is large, after each container is filled with the fillings, the total weight is large, the total stability is good, and large impacting energy can be borne; and the fillings are rock-soil bodies dug close to the piers to be protected, and are collected on the spot, so that the fillings are simple and convenient, and have economy and practicability.
