Assembled bridge piers with vibration damping function

Abstract

The invention discloses an assembly type pier with a vibration reduction function. The assembly type pier comprises a plurality of assembly units which can be sequentially spliced into a whole from bottom to top; each assembly unit comprises a pier unit body and a vibration reduction ring body; the top of each pier unit body protrudes outwards to form a boss, the bottom of each pier unit sinks inwards to form a groove, the outer diameters of the bosses are equal to the inner diameters of the grooves, and the height of the bosses is larger than the depth of the grooves; the vibration reductionring bodies sleeve outside the bosses, and the height of the vibration reduction ring bodies is equal to the difference between the height of the bosses and the depth of the grooves; and each vibration reduction ring body comprises a closed annular shell, shaft sleeves, blades, hollow hemispheres, solid balls and liquid. According to the assembled type pier with the vibration damping function, thevibration amplitude and the vibration frequency of the pier can be reduced, and the wind load, the driving load and the influence of the earthquake on the pier can be reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to an assembled bridge pier with vibration damping function. Background technique [0002] Prefabricated piers are a bridge construction technology that directly assembles on the construction site after prefabricating each assembly unit in the factory. It can reduce construction costs, shorten the construction period, and reduce the impact on traffic and the environment around the construction site. Assembled bridge piers will vibrate under the influence of external factors such as wind load and driving load. If the vibration amplitude of the bridge piers is large and the frequency is high, it will affect the service life of the bridge. more serious. [0003] Therefore, in order to solve the above problems, there is a need for an assembled bridge pier with a vibration damping function, which can reduce the vibration amplitude and frequency of the bridge pier...
