Anti-collision device for bridge pier

Abstract

The invention belongs to the technical field of anti-collision engineering of bridges, and provides an anti-collision device of a pier. The anti-collision device of the pier is provided with an anti-collision inner ring arranged on the periphery of the pier. The anti-collision inner ring (3) is in a ring shape formed by combining a plurality of rigid hollow boxes. The position between the anti-collision inner ring (3) and the pier (1) is filled with a plurality of buffers (2). An anti-collision outer ring is arranged on the outer side of the anti-collision inner ring (3), and the anti-collision outer ring (5) is of a shuttle-shaped structure formed by combining a plurality of rigid hollow boxes. A plurality of cavities used for containing nonlinear steel wire rope buffer energy absorbers (6) are formed in the two ends of the shuttle-shaped structure of the anti-collision outer ring (5). Roller support rings (8) are arranged on the outer wall face of the anti-collision outer ring (5) and are arranged up and down in at least two layers, and steel glue composite rollers (9) are arranged between the two up-and-down adjacent layers of roller support rings (8). The anti-collision device has important significance in guaranteeing ship traffic safety and bridge operation safety.

Description

technical field [0001] The invention belongs to the technical field of anti-collision engineering of bridges, and in particular relates to an anti-collision device for bridge piers. Background technique [0002] In the past two decades, my country has built nearly a hundred cross-river and sea-crossing bridges, many of which are super projects that have attracted worldwide attention. There are still deficiencies in anti-collision design and anti-collision measures; my country's bridge anti-collision research started late, and the early attention was not enough. The anti-collision design theory and calculation methods mostly refer to foreign research results; The pier anti-collision device that buffers the impact force of the ship on the pier and can turn the ship through the yaw mechanism so that most of the kinetic energy is taken away by itself is imperative, so as to achieve "the bridge is not damaged, the ship is not damaged, and the anti-collision device not bad" design i...
