Abstract

The invention discloses a damping device for a prefabricated pier. The damping device is used for swinging vibration reduction of the flexible high pier and comprises a curved channel formed in the pier, and the outer arc surface of the curved channel is downward. A damping component is arranged in the curved channel and has a first position and a second position; in the first position, the damping component is located at the lowermost point of the curved channel; and in the second position, the damping component leaves the lowermost point of the curved channel, and the damping component located in the second position has the tendency of moving to the lowermost point of the curved channel. The invention further discloses a damping method. By means of the damping device provided by the invention, vibration of the flexible high pier in the using stage after a bridge is constructed can be reduced.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a damping device for an assembled bridge pier, which is used for swing damping of a flexible high pier; the application also relates to a damping method. Background technique [0002] Bridges are key facilities in the construction of expressway networks and modern urban three-dimensional traffic networks. At present, bridges are designed to meet safety and durability. Generally, on-site construction will interfere with traffic and cause great damage to the environment. [0003] Later, prefabricated segmental assembly piers appeared, which adopt the process of factory prefabricated segments and on-site assembly, which can improve the quality of component production, shorten the construction period, reduce the construction area, and make later maintenance and dismantling more convenient and economical, reducing the entire life cycle. cost. Among them, ...
