Pier anti-collision buffering method

A pier anti-collision buffering method solves the problem that collision force directly acts on a pier, and the pier is damaged. According to the technical method needing to be achieved, a first rubber ring, a steel ring and a second rubber ring are arranged on the outer side of the pier, and rainproof cloth wraps the first rubber ring and winds around the bottom of the first rubber ring and the bottom of the steel ring and extends out from the upper portion of the second rubber ring, and the interior is sealed. An outer baffle is arranged on the outer side of an inner baffle, an energy reducing ring is welded to the upper portion of the inner side of the outer baffle, an energy reducing sleeve is welded to the corresponding position of the outer side of the inner baffle, and a spring is fixedly arranged at the lower portion of the inner side of the outer baffle. A pre-tightening screw is arranged at the corresponding position of the outer side of the inner baffle and connected with one end of the spring. A s
