Problems solved by technology

[0003] During the use of the bridge, vibration will be generated, and the vibration is very harmful to the bridge, especially the bridge pier. When the bridge pier has an anti-seismic effect, it can greatly improve the service life of the bridge. Nowadays, shock absorbers are generally used for the earthquake resistance of bridge piers. The way to alleviate, and the shock absorber has a service life, and it will be greatly reduced if the installation is not in place, affecting the use

Abstract

The invention discloses a bridge pier with an earthquake proof effect. The bridge pier comprises a bridge pier body, wherein the middle part of the bridge pier body is provided with a thick steel bar;a plurality of fine steel bars are uniformly arranged in the bridge pier body around the thick steel bar; the bridge pier body is prepared from the following ingredients including cement, fly ash, bentonite, polymer fiber, steel-wire-like fiber, dibenzoyl peroxide, polytetrafluoroethylene, silicon dioxide and water. The bridge pier has the advantages that the structure is simple; the earthquake proof effect is good; the weather resistant performance is good.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a bridge pier with anti-seismic effect. Background technique [0002] The bridge pier is a sub-structure that supports the bridge span structure and transmits the constant section and vehicle live load to the foundation. [0003] During the use of the bridge, vibration will be generated, and the vibration is very harmful to the bridge, especially the bridge pier. When the bridge pier has an anti-seismic effect, it can greatly improve the service life of the bridge. Nowadays, shock absorbers are generally used for the earthquake resistance of bridge piers. The shock absorber has a service life, and it will be greatly reduced if the installation is not in place, which will affect the use. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a bridge pier with anti-seismic effect, which has a simple structure, good anti-seis...
