A Bridge Structure Suitable for Uneven Settlement of Piers

Abstract

The invention provides a bridge beam structure applicable to differential settlement of piers and relates to the technical field of bridge beams. The bridge beam structure applicable to differential settlement of the piers comprises piers. Supporting columns are fixedly connected to the top ends of the piers. Bridge beams are fixedly connected to the top ends of the supporting columns. Connectingdevices are fixedly connected between the bridge beams. A soft base face is attached to the top ends of the bridge beams. A bridge face laying device is laid on the top end of the soft base face. An early warning device is fixedly connected to the front ends of the connecting portions of the bridge beams. According to the bridge beam structure applicable to differential settlement of the piers, the sinking and protruding degree of the connecting portions of the bridge beams when settlement of the bridge beams is not uniform is reduced, the comfort degree of traveling on the bridge face is improved, when the bridge beams deform to a certain degree due to uneven settlement, a warning lamp can be electrified, maintainers are reminded to carry out maintaining in time, and the phenomenon that due to severe uneven settlement of the bridge beams, collapsing occurs is avoided.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge structure suitable for uneven settlement of bridge piers. Background technique [0002] The continuous bridge superstructure is a commonly used structural form of bridges, but when the geological conditions of adjacent piers are quite different, or different foundation forms are used for some special reasons, it will cause uneven settlement of the bridge foundation. Settlement is very unfavorable to the stress on the bridge structure, and it is easy to cause the bridge deck to break. [0003] In order to meet the deformation requirements of the bridge deck, the existing bridge structure usually uses bridge expansion joints to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge building materials, but its driving comfort is poor, and the construction process is complicated. The bridge structure uses a soft base to cover th...

[0002] The continuous bridge superstructure is a commonly used structural form of bridges, but when the geological conditions of adjacent piers are quite different, or different foundation forms are used for some special reasons, it will cause uneven settlement of the bridge foundation. Settlement is very unfavorable to the force of the bridge structure, and it is easy to cause the bridge deck to break

[0003] In order to meet the deformation requirements of the bridge deck, the existing bridge structure usually uses bridge expansion joints to adjust the displacement and connection between the superstructure caused by vehicle loads and bridge building materials, but its driving comfort is poor, and the construction process is complicated. The bridge structure uses a soft base to cover the expansion joints of the bridge. Although it can improve the driving comfort to a certain extent, there will still be low-lying and raised places, and when the bridge piers settle unevenly to a certain extent, the bridge will be understressed. Therefore, it is necessary to detect the uneven settlement of the bridge in real time
