Energy consumption type swing pier

Abstract

The invention relates to the technical field of bridges and particularly discloses an energy consumption type swing pier. The swing pier comprises a bridge floor, connecting seats, a first base, a bridge pier and a second base, wherein one end of the bridge pier is fixedly connected with the first base, the other end of the bridge pier is located in the second base, the connecting seats are symmetrically placed on the two sides of the upper surface of the first base, the bridge floor is located on the connecting seats, and an arc-shaped groove is formed in the second base; an arc-shaped groove is formed in the base, an arc-shaped block is arranged in the arc-shaped groove, the arc-shaped block can deflect in the arc-shaped groove, one end of the pier is fixedly connected with the middle of the arc-shaped block, at least two sets of swing mechanisms are arranged above the base, every two adjacent sets of swing mechanisms are connected in a clamped mode, and the pier penetrates through the middles of the swing mechanisms; and the pier is in sliding connection with the swinging mechanism. According to the swing pier, the anti-seismic effect of the bridge is improved, and damage of earthquakes to the bridge is reduced.

Description

technical field [0001] The invention relates to the technical field of bridges, and specifically discloses an energy-consuming swing pier. Background technique [0002] my country is located between the circum-Pacific seismic belt and the Eurasian seismic belt. Most of the country is an earthquake zone, especially the western part of my country is mostly a strong earthquake zone with frequent seismic activities. The bridge is a pivotal project of the traffic lifeline, and its construction cost is high. Once it is damaged by an earthquake, it will cause huge economic losses, and it is extremely difficult to repair after the earthquake. The number of casualties directly on the bridge was not many, but the economic losses and casualties caused by the damage and interruption of traffic lifelines were immeasurable, resulting in rescue personnel not being in place in time, and many people were exacerbated by the earthquake disaster because they did not receive timely rescue. At t...

The bridge is a pivotal project of the traffic lifeline, and its construction cost is high. Once it is damaged by an earthquake, it will cause huge economic losses, and it is extremely difficult to repair after the earthquake

The number of casualties directly on the bridge is not many, but the economic losses and casualties caused by the damage and interruption of the traffic lifeline are immeasurable, resulting in the failure of rescue personnel to arrive in time, and many people have aggravated the earthquake disaster because they did not receive timely rescue.

At the same time, it is difficult to repair the damaged large bridges, which seriously affects the production and life in the disaster area and the post-disaster reconstruction work

The current seismic design of bridges is mainly based on the ductile seismic design of the hysteretic performance of reinforced concrete piers, but it is difficult to repair the damage and destruction of the plastic hinge area of ​​bridge piers
